                                  PART I.

Item 1.    Business

      General

      Commonwealth Energy System, a Massachusetts trust, is an unincorporated
business organization with transferable shares.  It is organized under a
Declaration of Trust dated December 31, 1926, as amended, pursuant to the laws
of Massachusetts.  It is an exempt public utility holding company under the
provisions of the Public Utility Holding Company Act of 1935, holding all of
the stock of four operating public utility companies.  Commonwealth Energy
System, the parent company, is referred to in this report as the "System" and,
together with its subsidiaries, is collectively referred to as "the system."

      The operating utility subsidiaries of the System are engaged in the
generation, transmission and distribution of electricity and the distribution
of natural gas, all within Massachusetts.  These subsidiaries are:

              Electric                                  Gas

     Cambridge Electric Light Company        Commonwealth Gas Company
     Canal Electric Company
     Commonwealth Electric Company

      In addition to the utility companies, the System also owns all of the
stock of a steam distribution company (COM/Energy Steam Company), five real
estate trusts and a liquefied natural gas (LNG) and vaporization facility
(Hopkinton LNG Corp.).  Subsidiaries of the System have common executive and
financial management and receive technical assistance as well as financial,
data processing, accounting, legal and other services from a wholly-owned
services company subsidiary (COM/Energy Services Company).

      The five real estate subsidiaries are:  Darvel Realty Trust, which is a
joint-owner of the Riverfront Office Park complex in Cambridge; COM/Energy
Acushnet Realty, which leases land to Hopkinton LNG Corp.; COM/Energy Research
Park Realty, which was organized to develop a research building in Cambridge;
COM/Energy Cambridge Realty, which was organized to hold various properties;
and COM/Energy Freetown Realty (Freetown), which was organized in 1986 to
purchase and develop 596 acres of land in Freetown, Massachusetts.  As a
result of unsuccessful efforts to develop an energy park on this site, the
System announced on January 23, 1992 its decision to write down its investment
in the Freetown project.  This action resulted in the recognition of a charge
(net of tax) of $14.8 million in 1991.

      Each of the operating utility subsidiaries previously listed serves
retail customers except for Canal Electric Company (Canal) which operates an
electric generating station located at the eastern end of the Cape Cod Canal
in Sandwich, Massachusetts.  The station consists of two oil-fired steam
electric generating units: Canal Unit 1, with a rated capacity of 569 MW,
wholly-owned by Canal; and Canal Unit 2, with a rated capacity of 580 MW,
jointly-owned by Canal and Montaup Electric Company (Montaup) (an unaffiliated
company).  Canal Unit 2 is operated under an agreement with Montaup which
provides for the equal sharing of output, fixed charges and operating expen-
ses.  In October 1993, Canal reached an agreement with Montaup and Algonquin
                                  PAGE 4

                        COMMONWEALTH ENERGY SYSTEM

Gas Transmission Company to build a natural gas pipeline that will serve Unit
2, subject to regulatory approvals.  The project will improve air quality on
Cape Cod, enable the plant to exceed the stringent 1995 air quality standards
established by the Massachusetts Department of Environmental Protection and
strengthen Canal's bargaining position as it seeks to secure the lowest-cost
fuel for its customers.  Plant conversion and pipeline construction are
expected to be completed in 1996.

      Electric service is furnished by Cambridge Electric Light Company (Cam-
bridge Electric) and Commonwealth Electric Company (Commonwealth Electric) at
retail to approximately 304,000 year-round customers in 41 communities in
eastern Massachusetts covering 1,112 square miles and having an aggregate
population of 645,000.  The system also serves approximately 48,000 seasonal
retail customers.  The territory served includes the communities of Cambridge,
New Bedford and Plymouth and the geographic area comprising Cape Cod and
Martha's Vineyard.  Cambridge Electric also sells power at wholesale to the
Town of Belmont, Massachusetts.

      Natural gas is distributed by Commonwealth Gas Company (Commonwealth
Gas) to approximately 232,000 customers in 49 communities in central and
eastern Massachusetts covering 1,067 square miles and having an aggregate
population of 1,128,000.  Twelve of these communities are also served by
system companies with electricity.  Some of the larger communities served by
Commonwealth Gas include Cambridge, Somerville, New Bedford, Plymouth,
Worcester, Framingham, Dedham and the Hyde Park area of Boston.

      The results of the 1990 federal census taken in the system's electric
and gas service areas indicated an increase in population of 15.2% and 12%,
respectively, since 1980.

      Steam, which is produced by Cambridge Electric in connection with the
generation of electricity, is purchased by COM/Energy Steam and, together with
its own production, is distributed to 20 customers in Cambridge and 1 customer
(Massachusetts General Hospital) in Boston. Steam is used for space heating
and other purposes.  On August 17, 1993 COM/Energy Steam began providing steam
service to Genzyme Corporation (Genzyme), a biotechnology company that is
expected to become one of the largest customers of COM/Energy Steam. 
Genzyme's steam need for 1994 is estimated to be 160 million pounds, which
represents approximately 10% of steam unit sales, for heating, air
conditioning and testing processes.  After 1994, Genzyme's annual requirement
is estimated to reach approximately 230 million pounds upon commercial
manufacturing of a biotherapeutic product in 1995.  New England Confectionery
Company (Necco), began receiving steam service in October 1992 and is the
fourth largest customer of COM/Energy Steam.

      Industry in the territories served by system companies is highly
diversified.  The larger industrial customers include high-technology firms
and manufacturers of such products as photographic equipment and supplies,
rubber products, textiles, wire and other fastening devices, abrasives and
grinding wheels, candy, copper and alloys, and chemicals.  Among customers
served are several major educational institutions, including Harvard
University and the Massachusetts Institute of Technology (MIT).

      Presently, MIT is constructing a 19 MW natural gas-fired cogeneration
facility which is expected to be completed in January 1995.  MIT expects that
this cogeneration facility will meet approximately 94% of its power, heating
and cooling requirements.  Sales to MIT in 1993 accounted for approximately
1.9% of consolidated unit sales.  MIT and Cambridge Electric are presently
negotiating a buy and sell arrangement which will require the approval of the
Massachusetts Department of Public Utilities (DPU).

      Electric Power Supply

      To satisfy demand requirements and provide required reserve capacity,
the system supplements its generating capacity by purchasing power on a long
and short-term basis through capacity entitlements under power contracts with
other New England and Canadian utilities and with Qualifying Facilities and
other non-utility generators through a competitive bidding process that is
regulated by the DPU.

      System companies own generating facilities with a capability totaling
967.1 MW.  Included in this amount is 569 MW provided by Canal Unit 1, of
which three-quarters (427 MW) is sold to neighboring utilities under long-term
contracts, and 220.5 MW provided by Canal Unit 2.  In 1991, Canal executed an
exchange transaction with Central Vermont Public Service Corporation (CVPS)
whereby 50 MW of Canal Unit 2 was exchanged for 25 MW each of CVPS's entitle-
ment in the Vermont Yankee nuclear power plant and the Merrimack 2 coal-fired
unit through October 1995.  These contracts are designed to reduce the
system's reliance on oil.  Additionally, in 1993, Canal executed an exchange
transaction with New England Power Company (NEP) whereby 20 MW of Canal Unit 2
was exchanged for 20 MW of Bear Swamp Unit Nos. 1 and 2 through October 1993. 
As of November 1, 1993, the exchange was increased to 50 MW through April
1997.  The Bear Swamp Units are pumped storage hydro electric generating
facilities.  Another 128.3 MW is provided by various smaller system units.  Of
the 540.3 MW available to the system, 65.3 MW are used principally for peaking
purposes.  A 3.52% ownership interest in the Seabrook 1 nuclear power plant
provides 40.5 MW of capability to the system and Central Maine Power Company's
Wyman Unit 4, an oil-fired facility in which the system has a 1.4% joint-
ownership interest, provides 8.8 MW.

      In addition, through Canal's equity ownership in Hydro-Quebec Phase II,
the system has an entitlement of 67.9 MW.  Long-term purchase arrangements are
also in place with the following natural gas-fired cogenerating units in
Massachusetts: 23.8 MW from the Consolidated Power Company, 31.4 MW from Pep-
perell Power Associates and 43.9 MW from Northeast Energy Associates and
effective July 31 and September 1, 1993, 51 MW and 55 MW from Masspower and
Altresco Pittsfield, respectively.  Additionally, the system receives 67.0 MW
from the SEMASS waste-to-energy plant (which includes 20.8 MW from the
expansion unit which went on-line May 17, 1993); has entitlements totaling
41.6 MW through contracts with five (5) hydroelectric suppliers, including
29.1 MW of pumped storage capacity from New England Power's Bear Swamp Units 1
and 2 and 10 MW from Boott Hydropower, Inc., in Lowell, Massachusetts; and
also receives 61.8 MW from a natural gas-fired independent power producer,
Dartmouth Power Associates.  The system anticipates providing for future peak
load plus reserve requirements through existing and planned system generation,
including purchasing available capacity from neighboring utilities and/or non-
utility generators.

      In addition, the system has available 140.7 MW from four (4) nuclear
units in which system distribution companies have life-of-the-unit contracts
for power.  Information with respect to these units is as follows:

      On February 26, 1992, the Yankee Atomic Electric Company (Yankee) board
of directors agreed to permanently cease power operation of the Yankee nuclear
power plant in Rowe, Massachusetts.  For additional information, refer to Note
2(e) of the Notes to Consolidated Financial Statements filed under Item 8 of
this report.

      On October 1, 1992, Commonwealth Electric ceased power generation at its
60 MW Cannon Street generating station located in New Bedford, Massachusetts. 
During the past few years, the plant had been used primarily to meet peak
electric demand and as a backup unit for Commonwealth Electric and the New
England Power Pool (NEPOOL) when other area units were taken off line.  A
sharp decline in electric demand brought about by the present economic
slowdown was the key factor in management's decision to close the plant. 
Additionally, forecasts for electric demand indicated an excess regional
supply in the near term and no need for increased generating capacity until
the late-1990s or beyond.  Commonwealth Electric made the decision during the
second quarter of 1993 to abandon the plant and transfer its net book value to
a regulatory asset subsequent to FERC approval.  This decision was viewed as
the most cost effective among several alternatives and leaves Commonwealth
Electric with the most flexibility for future capacity planning.

      Cambridge Electric, Canal and Commonwealth Electric, together with other
electric utility companies in the New England area, are members of NEPOOL,
which was formed in 1971 to provide for the joint planning and operation of
electric systems throughout New England.

      NEPOOL operates a centralized dispatching facility to ensure reliability
of service and to dispatch the most economically available generating units of
the member companies to fulfill the region's energy requirement.  This concept
                                  PAGE 7

                        COMMONWEALTH ENERGY SYSTEM

is accomplished by use of computers to monitor and forecast load requirements
and provide for the economic dispatching of generation.

      NEPOOL, on behalf of its members entered into an Interconnection Agree-
ment with Hydro-Quebec, a Canadian utility operating in the Province of
Quebec.  The agreement provided for construction of an interconnection (Phase
I) between the electrical systems of New England and Quebec.  The parties have
also entered into an Energy Contract and an Energy Banking Agreement; the
former obligates Hydro-Quebec to offer NEPOOL participants up to 33 million
MWH of surplus energy during an eleven-year term that began September 1, 1986
and the latter provides for energy transfers between the two systems.  The
Phase I Interconnection began operation in October 1986.  NEPOOL has also
entered into Phase II agreements for an additional purchase from Hydro-Quebec
of 7 million MWH per year for a twenty-five year period which began in late
1990.

      The System's electric subsidiaries are also members of the Northeast
Power Coordinating Council (NPCC), an advisory organization that includes the
major power systems in New England and New York plus the Provinces of Ontario
and New Brunswick in Canada.  NPCC establishes criteria and standards for
reliability and serves as a vehicle for coordination in the planning and
operation of these systems in enhancing reliability.

      The reserve requirements used by the NEPOOL participants in planning
future additions are determined by NEPOOL to meet the reliability criteria
recommended by NPCC.  The system estimates that, during the next ten years,
reserve requirements so determined will be in the range of 23% to 29% of peak
load.

      Power Supply Commitments and Support Agreements

      Cambridge Electric and Commonwealth Electric, through Canal, secure cost
savings for their respective customers by planning for bulk power supply on a
single system basis.  Additionally, Cambridge Electric and Commonwealth
Electric have long-term contracts for the purchase of electricity from various
sources.  Generally, these contracts are for fixed periods and require payment
of a demand charge for the capacity entitlement and an energy charge to cover
the cost of fuel.

      The system's 3.52% interest in the Seabrook nuclear power plant is owned
by Canal to provide for a portion of the capacity and energy needs of Cam-
bridge Electric and Commonwealth Electric.  Canal began recovering 100% of its
Seabrook investment through a power contract with Cambridge Electric and
Commonwealth Electric in June 1990, subject to refund pending a full review of
Canal's investment in the unit by the Federal Energy Regulatory Commission
(FERC).  In November 1991, the FERC approved a settlement agreement which
resolved all Seabrook cost-of-service issues (except rate of return).  In
December 1991, a FERC Administrative Law Judge (ALJ) affirmed the prudence of
Canal's investment in Seabrook and on January 29, 1992, the FERC approved a
settlement proposal that allows a return on equity of 11.72%.  The ALJ's
decision was approved by the full commission in a final order issued on
                                  PAGE 8

                        COMMONWEALTH ENERGY SYSTEM

August 4, 1992.  For additional information concerning Seabrook 1, refer to
Note 2(b) of Notes to Consolidated Financial Statements filed under Item 8 of
this report.

      In response to solicitations made to NEPOOL member companies by
Northeast Utilities (NU), Canal, on behalf of Commonwealth Electric and
Cambridge Electric, agreed to purchase entitlements through various contracts
ranging up to five years in length.  The terms of the five-year agreement
stipulate the purchase of 50 MW, on average, from NU annually from November
1989 through October 1994.  Commonwealth Electric and Cambridge Electric are
each appropriated a portion of the power received from NU based on need. 
These and other bulk electric power purchases are necessary in order to
fulfill the system's NEPOOL obligation and to meet Commonwealth Electric and
Cambridge Electric capacity requirements.

      Canal has entered into support agreements for Phase I and Phase II of
the Hydro-Quebec Project.  Canal is obligated to pay its share of operating
and capital costs for Phase II over a 25 year period ending in 2015.  Future
minimum lease payments for Phase II have an estimated present value of $14.2
million at December 31, 1993.  In addition, Canal has an equity interest in
Phase II which amounted to $3.9 million in 1993 and $4.2 million in 1992.

      Electric Fuel Supply

      (a) Oil

      Imported residual oil is the fuel used in the generation of power in
system generating plants, producing approximately 31% of the system's total
energy requirement for 1993.

      Effective July 1, 1993, Canal executed a twenty-two month contract with
Coastal Oil of New England, Inc. (Coastal) for the purchase of residual fuel
oil.  The contract provides for delivery of a set percentage of Canal's fuel
requirement, the balance (a maximum of 20%) to be met by spot purchases or by
Coastal at the discretion of Canal.

      Energy Supply and Credit Corporation (ESCO) operates Canal's oil
terminal for the purchase, receipt and payment of oil under assignment of
Canal's supply contracts to ESCO (Massachusetts), Inc.  Oil in the terminal's
tanks is held in inventory by ESCO and delivered upon demand to Canal's tanks.

      Fuel oil storage facilities at the Canal site have a capacity of
1,199,000 barrels, representing 60 days of normal operation of the two units. 
During 1993, ESCO maintained an average daily inventory of 583,000 barrels of
fuel oil which represents 30 days of normal operation of the two units.  This
supply is maintained by tanker deliveries approximately every ten to fifteen
days.

Financial Condition and Results of Operations," for a discussion of the cost
of fuel oil.

                        COMMONWEALTH ENERGY SYSTEM

      (b) Nuclear Fuel Supply and Disposal

      Approximately 26% of the system's total energy requirement for 1993 was
generated by nuclear plants.  The nuclear fuel contract and inventory
information for Seabrook 1 has been furnished to the system by North Atlantic
Energy Services Corporation (NAESCO), the plant manager responsible for
operation of the unit.

      The supply of fuel for nuclear generating plants generally involves the
acquisition of uranium concentrate, its conversion to uranium hexafluoride,
enrichment, fabrication of the nuclear fuel assemblies and disposition through
reprocessing or storage of spent fuel.  Seabrook's requirements for each of
these fuel components are 100% covered through 1999 by existing contracts.

      There are no spent fuel reprocessing or disposal facilities currently
operating in the United States.  Instead, commercial nuclear electric
generating units operating in the United States are required to retain high
level wastes and spent fuel on-site.  As required by the Nuclear Waste Policy
Act of 1982 (the Act), as amended, the joint-owners entered into a contract
with the Department of Energy for the transportation and disposal of spent
fuel and high level radioactive waste at a national nuclear waste repository. 
Owners or generators of spent nuclear fuel or its associated wastes are
required to bear all of the costs for such transportation and disposal through
payment of a fee of approximately 1 mill/KWH based on net electric generation
to the Nuclear Waste Fund.  Under the Act, a temporary storage facility for
nuclear waste was anticipated to be in operation by 1998; however, a reassess-
ment of the project's schedule requires extending the completion date of the
permanent facility until at least 2010.  Seabrook 1 is currently licensed for
enough on-site storage to accommodate all spent fuel expected to be accumulat-
ed through the year 2010.

      Gas Supply

      In April 1992, the FERC issued Order 636 which became effective on
November 1, 1993 and requires interstate pipelines to unbundle existing gas
sales contracts into separate components (gas sales, transportation and
storage services).  Order 636 provides mechanisms which will allow customers
such as Commonwealth Gas to reduce the level of firm services from the
pipelines and "broker" excess capacity on a temporary or permanent basis. 
Order 636 also requires pipelines to provide transportation services that
allow customers to receive the same level of service they had with the bundled
contracts.  In the past, Commonwealth Gas purchased the majority of its gas
supplies from either Tennessee Gas Pipeline Company (Tennessee) or Algonquin
Gas Transmission Company (Algonquin), a wholly-owned subsidiary of Texas
Eastern Transmission Company (Texas Eastern), supplemented with third-party
firm gas purchases and firm transportation from the various pipelines. 
Presently, Commonwealth Gas has only transportation, storage, and balancing
contracts with these pipelines (and other upstream pipelines that bring gas
from the supply wells to the final transporting pipelines), and contracts with
a variety of independent vendors for firm gas supply.  Twelve new firm gas
supply contracts have been negotiated with suppliers and filed with the DPU. 
During the interim, Commonwealth Gas is operating under short-term firm
agreements with these same vendors to provide firm supplies under similar
terms and conditions as the long-term agreements, which are presently under
review.  Approvals are expected during the first half of 1994.
                                  PAGE 10

                        COMMONWEALTH ENERGY SYSTEM

      In addition to firm transportation and gas supplies mentioned above,
Commonwealth Gas utilizes contracts for underground storage and LNG facilities
to meet its winter peaking demands.  The underground storage contracts are a
combination of existing agreements, that have been in existence for many
years, and new agreements which are the result of Order 636 requirements for
total service unbundling.  The LNG facilities, described below, are used to
liquefy and store pipeline gas during the warmer months for use during the
heating season.  During 1993, over 99% of the gas utilized by Commonwealth Gas
was delivered by the interstate pipeline system, the remaining small quantity
(approximately 360,000 MMBTU) was delivered as liquid LNG from Distrigas of
Massachusetts.

      Commonwealth Gas entered into a multi-party agreement to assume a
portion of Boston Gas Company's contracts to purchase Canadian gas supplies
from Alberta Northeast (ANE), and have the volumes delivered by the Iroquois
Gas Transmission System and Tennessee pipelines.  The ANE gas supply contract
was filed with the DPU and hearings were completed in April 1993. 
Commonwealth Gas is currently awaiting an order from the DPU.

      Commonwealth Gas began transporting gas on its distribution system in
1990 for end-users.  There are currently only eleven customers using this
transportation service, accounting for only 1,623 BBTU of throughput in 1993
which represented approximately 3.5% of system throughput.

      Hopkinton LNG Facility

      A portion of the system's gas supply during the heating season is
provided by Hopkinton LNG Corp. (Hopkinton), a wholly-owned subsidiary of the 
System.  The facility consists of a liquefaction and vaporization plant and
three above-ground cryogenic storage tanks having an aggregate capacity of
3 million MCF of natural gas.

      In addition, Hopkinton owns a satellite vaporization plant and two
above-ground cryogenic storage tanks located in Acushnet, Massachusetts with
an aggregate capacity of 500,000 MCF of natural gas and are filled with LNG
trucked from Hopkinton.

      Commonwealth Gas has a contract for LNG service with Hopkinton extending
through 1996, thereafter renewable year to year with notice of termination due
five years in advance.  Contract payments include a demand charge sufficient
to cover Hopkinton's fixed charges and an operating charge which covers
liquefaction and vaporization expenses.  Commonwealth Gas furnishes pipeline
gas during the period April 15 to November 15 each year for liquefaction and
storage.  As the need arises, LNG is vaporized and placed in the distribution
system of Commonwealth Gas.

      Based upon information presently available regarding projected growth in
demand and estimates of availability of future supplies of pipeline gas, the
System believes that its present sources of gas supply are adequate to meet
existing load and allow for future growth in sales.

      Rates, Regulation and Legislation

      Certain of the System's utility subsidiaries operate under the jurisdic-
tion of the DPU, which regulates retail rates, accounting, issuance of secur-
ities and other matters.  In addition, Canal and Cambridge Electric file their
respective wholesale rates with the FERC.

      (a) Most Recent Rate Case Proceedings

      Electric

      On May 28, 1993, the DPU issued an order increasing Cambridge Electric's
retail revenues by approximately $7.2 million, or 6.4%.  The rates, based on a
June 30, 1992 test-year and effective June 1, 1993, provide an overall return
of 9.95%, including an equity return of 11% and represented approximately 70%
of the amount requested.  The new rates will have a positive impact on net
income for the balance of 1993 and beyond.  More than 80% of the increase
related to: 1) plant additions since Cambridge Electric's last retail rate
proceeding in 1989; 2) capacity costs associated with certain purchased power
contracts; and 3) costs of postretirement benefits other than pensions.  The
costs associated with these postretirement benefits were determined in
accordance with Statement of Financial Accounting Standards No. 106,
"Employers' Accounting for Postretirement Benefits Other Than Pensions,"
issued in 1990 and adopted as of January 1, 1993.  The DPU authorized recovery
of these costs over a four-year period with carrying costs on the deferred
portion.  The new base rates also reflect the roll-in of costs associated with
the Seabrook nuclear power plant which are billed to Cambridge Electric by
Canal.  Previously these costs were recovered through Cambridge Electric's
Fuel Charge decimal.

      On May 17, 1989, Cambridge Electric filed for an increase in its base
rates using a 1988 test-year.  On August 31, 1989, the DPU approved an Offer
of Settlement between the parties which resolved all revenue requirements
issues.  Cambridge Electric was allowed to increase annual revenues by
$4,438,000 or 5.5% of total test-year revenue, approximately 73% of the
$6,111,000 originally requested.  The new rates became effective on December
18, 1989 and represented the first increase in Cambridge Electric's rates
since 1982.

      On July 1, 1991, the DPU issued an order increasing Commonwealth Elec-
tric's retail electric revenues by $10.9 million, or 3.1%.  The requested
increase was $17.3 million.  The order, based on a June 30, 1990 test-year,
provided an overall return of 10.49%, including a return on equity of 12%. 
The DPU ordered the restructuring of the Company's rates to more closely
reflect the actual cost of providing service to each customer class.  The DPU  
also ordered Commonwealth Electric to undertake an independent management
audit to address, among other areas, its management, planning and control
practices.  In February 1992, Ernst & Young was selected by the DPU from three
management consulting firms submitted by Commonwealth Electric to perform the
audit which began on March 6, 1992.  On October 9, 1992, the DPU released the
results of the audit which evaluated existing activities and processes and
identified opportunities for improved operations in the areas of strategic
planning, budget development, control of capital and operations costs,
management of outside services, employment policies and customer services.

                                  PAGE 12

                        COMMONWEALTH ENERGY SYSTEM

Throughout 1993, follow-up discussions were held between Commonwealth Electric
and the DPU regarding the status of each audit recommendation with both
parties expressing overall satisfaction with their progress.  Changes in the
implementation plan were discussed, with the plan expected to be completed in
1994.

      In January 1989, Commonwealth Electric received authorization from the
DPU to increase base revenues by $18 million or 6.6% of total test-year
revenues.  This increase, representing approximately 77% of its original $23.3
million request, included an overall rate of return of 10.89% and a return on
common equity of 13%.  It represented the first increase in Commonwealth Elec-
tric's base rates since 1982.

      Gas

      On April 16, 1991, Commonwealth Gas requested a $27.7 million (11.3%)
revenue increase in a filing with the DPU using a test-year ended December 31,
1990.  On September 16, 1991, the DPU approved a settlement of the revenue
requirements portion of the filing authorizing a $22.8 million increase in
annual revenues, approximately 82% of the original request.  The agreement
included a return on equity, for accounting purposes, of 13%.  The DPU later
ruled on the rate design portion of the request and the new rates went into
effect on November 1, 1991.  The increase was necessitated by the rising costs
of providing service to customers and substantial expenditures to upgrade,
improve and maintain the Commonwealth Gas distribution system.

      (b) Wholesale Rate Proceedings

      Cambridge Electric requires FERC approval to increase its wholesale
rates to the Town of Belmont, Massachusetts (Belmont), a "partial
requirements" customer since 1986.  These rates include a fuel adjustment
clause which reflects changes in costs of fuels and purchased power used to
supply Belmont.

      On March 23, 1990, Cambridge Electric filed a request with the FERC to
increase its wholesale rates to Belmont by $2,252,000 annually.  The request
was largely due to increased purchased power costs and major additions to
plant-in-service.  The proposed rates were accepted by the FERC, subject to
refund, on August 1, 1990.  On September 19, 1990, Cambridge Electric and
Belmont filed an uncontested Offer of Settlement which the FERC approved on
December 6, 1990 resolving all issues with the exception of Seabrook 1 costs
which were subject to change based upon the results of the FERC's final review
of Canal's investment in the unit.  This settlement required Cambridge
Electric to adjust its Belmont rate to reflect the final allocation of power
purchased by Canal on behalf of Cambridge Electric and Commonwealth Electric. 
Cambridge Electric made a refund to Belmont in August 1991 and filed the
requisite compliance report with the FERC on September 16, 1991.

      A settlement agreement between Canal and Belmont addressing all Seabrook
cost-of-service issues (except rate of return on common equity) was filed with
the FERC on April 16, 1991 and subsequently approved by the FERC on November
13, 1991.  In addition, this settlement changed the effective date of the
Belmont Service Agreement from August 1, 1990 to June 30, 1990.  The charges
and refunds resulting from this settlement were applied to Belmont's bill in
January 1992.
                                  PAGE 13

                        COMMONWEALTH ENERGY SYSTEM

      On November 12, 1991 a settlement agreement between Canal and Belmont
addressing the rate of return on common equity in the Seabrook Power Contract
was filed with the FERC.  The return on equity settlement, which was approved
by the FERC on January 29, 1992, allowed a return on equity of 11.72% and
required Canal to refund certain sums to Cambridge Electric and Commonwealth
Electric and to make a compliance report to the FERC.  On March 12, 1992,
Canal made its compliance filing with the FERC indicating that all refunds
were made to Cambridge Electric and Commonwealth Electric on February 27,
1992.

      As a result of the return on equity settlement, Cambridge Electric was
required to refund certain sums to Belmont.  On April 2, 1992 Cambridge made
its requisite compliance filing with the FERC indicating that refunds were
made to Belmont in the March 1992 billings.

      (c) Automatic Adjustment Clauses

          Electric

      Both Commonwealth Electric and Cambridge Electric have Fuel Charge rate
schedules which generally allow for current recovery, from retail customers,
of fuel used in electric production, purchased power and transmission costs.
These schedules require a quarterly computation and DPU approval of a Fuel
Charge decimal based upon forecasts of fuel, purchased power, transmission
costs and billed unit sales for each period.  To the extent that collections
under the rate schedules do not match actual costs for that period, an
appropriate adjustment is reflected in the calculation of the next subsequent
calendar quarter decimal.

      Cambridge Electric and Commonwealth Electric collect a portion of the
capacity-related purchased power costs associated with certain long-term power
arrangements through base rates.  The recovery mechanism for these costs uses
a per kilowatthour (KWH) factor that is calculated using historical (test-
period) capacity costs and unit sales.  This factor is then applied to current
monthly KWH sales.  When current period capacity costs and/or unit sales vary
from test-period levels, Cambridge Electric and Commonwealth Electric
experience a revenue excess or shortfall which can have a significant impact
on net income.  All other capacity and energy-related purchased power costs
are recovered through the Fuel Charge.  Cambridge Electric and Commonwealth
Electric made a filing in late 1992 with the DPU seeking an alternative method
of recovery.  This request was denied in a letter order issued on October 6,
1993.  However, Cambridge Electric and Commonwealth Electric were encouraged
by the DPU's acknowledgement that the issues presented warrant further
consideration.  The DPU encouraged each company to continue to work with other
interested parties, including the Attorney General of Massachusetts, to reach
a consensus solution on the issue for consideration in each company's next
base rate proceeding.

      Both Commonwealth Electric and Cambridge Electric have separately stated
Conservation Charge rate schedules which allow for current recovery, from
retail customers, of Conservation and Load Management program costs.  For
further information, refer to Management's Discussion and Analysis of
Financial Condition and Results of Operations filed under Item 7 of this
report.
                                  PAGE 14

                        COMMONWEALTH ENERGY SYSTEM

          Gas

      Commonwealth Gas has a Standard Seasonal Cost of Gas Adjustment rate
schedule (CGA) which provides for the recovery, from firm customers, of
purchased gas costs not collected through base rates.  These schedules, which
require DPU approval, are estimated semi-annually and include credits for gas
pipeline refunds and profit margins applicable to interruptible sales.  Actual
gas costs are reconciled annually as of October 31 and any difference is
included as an adjustment in the calculation of the decimals for the two
subsequent six-month periods.

      The DPU and the Massachusetts Energy Facilities Siting Council (the
Council) were merged in 1992.  The Council is now a division of the DPU.
Periodically, Commonwealth Gas is required to file a long-range forecast of
the energy needs and requirements of its market area and annual supplements
thereto with the Council.  To approve a long-range forecast, the Council must
find, among other things, that Commonwealth Gas plans for construction of new
gas manufacturing or storage facilities and certain high-pressure gas
pipelines are consistent with current health, environmental protection, and
resource use and development policies as adopted by the Commonwealth of
Massachusetts.  Commonwealth Gas filed a long-range forecast with the Council
on July 20, 1990 and updated aspects of the filing in March 1991.  This
forecast was combined with the DPU review of the ANE contract.  Both dockets
remain pending before the DPU.

      (d) Gas Demand, Take-or-Pay Costs and Transition Costs

      Commonwealth Gas is obligated, as part of its pipeline transportation
contracts and supplier gas purchase contracts, to pay monthly demand charges
which are recovered from customers through the CGA.

      In June 1991, Tennessee filed a settlement with the FERC dealing with a
variety of contract restructuring issues, including the allocation of take-or-
pay costs to Tennessee's customers including Commonwealth Gas.  This
comprehensive settlement was approved and implemented on July 1, 1992.  As
part of the settlement, the allocation of take-or-pay costs was changed from a
deficiency basis to a contract demand basis which increased Commonwealth Gas'
allocation.  Future take-or-pay costs will be included in Tennessee's
Temporary Gas Inventory Charge and transition costs under Tennessee's
restructuring pursuant to Order 636.

      Algonquin made a series of filings with the FERC to recover from its
customers take-or-pay charges imposed on it by its upstream suppliers. 
Algonquin billed Commonwealth Gas for gas supply inventory charges from Texas
Eastern and others through the Algonquin commodity rate.  With the
implementation of Order 636, Algonquin allocated the remaining costs utilizing
a formula based on actual purchases for the twelve months prior to May 1,
1993.  Commonwealth Gas' allocation was in excess of $5 million.  Commonwealth
Gas successfully appealed Algonquin's allocation method to the FERC.  The
change in allocation, combined with issues being settled in Algonquin's
current rate case will reduce Commonwealth Gas' allocated share by $1.5
million to $2.5 million.

      As a direct result of implementation of Order 636, most pipeline
companies are incurring transition costs which include the cost of
                                  PAGE 15

                        COMMONWEALTH ENERGY SYSTEM

restructuring gas supply contracts, the value of facilities that were
supporting the gas sales function and are no longer used and useful for
transportation only services, the cost of contracts with upstream pipeline
companies and various miscellaneous costs.  For additional information on
these transition costs refer to Note 2(g) of Notes to Financial Statements
filed under Item 8 of this report.

      Commonwealth Gas is collecting take-or-pay and other contract
restructuring costs from its customers through the CGA as permitted by the
DPU.  The remaining take-or-pay costs to be billed to Commonwealth Gas from
both Algonquin and Tennessee are estimated at approximately $431,000 as of
December 31, 1993, subject to change upon FERC approval.

      (e) Economic Development Rate

      Commonwealth Electric implemented an Economic Development Rate (EDR) on
October 1, 1991. The rate is available to new or existing industrial customers
who have an electric demand of 500 kilowatts or more and meet specific
financial criteria.  For additional information concerning the EDR, refer to
the "Economic Development Rate" section of "Management's Discussion and
Analysis of Financial Condition and Results of Operations" filed under Item 7
of this report.

      (f) Other

      Storm Damage Costs

      In August 1991, Commonwealth Electric's service territory was partic-
ularly hard hit by Hurricane Bob.  Its transmission and distribution system
suffered such extensive damage that its entire service territory (with minor
exceptions) was without power at one point.  Commonwealth Electric's franchise
is located entirely within four of the ten Massachusetts counties which were
declared federal disaster zones.

      In April 1992, the DPU approved an offer of settlement between
Commonwealth Electric, the Attorney General of Massachusetts and a Cape Cod
consumer group relating to certain costs associated with this storm.  For
further information on this settlement, refer to Note 3 of Notes to
Consolidated Financial Statements filed under Item 8 of this report.

      Segment Information

      System companies provide electric, gas and steam services to retail
customers in service territories located in central and eastern Massachusetts
and, in addition, sell electricity at wholesale to Massachusetts customers. 
Other operations of the system include the development and management of new
real estate ventures and operation of rental properties and other investment
activities which do not presently contribute significantly to either revenues
or operating income.

      Reference is made to additional industry segment information in Note 11
of Notes to Consolidated Financial Statements filed under Item 8 of this re-
port.

                        COMMONWEALTH ENERGY SYSTEM

      Environmental Matters

      The system is subject to laws and regulations administered by federal,
state and local authorities relating to the quality of the environment. 
Compliance with these laws and regulations has required capital expenditures
by the system for the period 1968 through 1993 of approximately $51.8 million,
$29.7 million of which was for facilities and studies at Seabrook.  Additional
capital expenditures through 1998 will require an estimated $25.1 million.

      For additional information concerning environmental issues including
those relating to former gas manufacturing sites, refer to the "Environmental
Matters" section of "Management's Discussion and Analysis of Financial Condi-
tion and Results of Operations" filed under Item 7 of this report.

      Construction and Financing

      For information concerning the system's financing and construction
programs refer to Management's Discussion and Analysis of Financial Condition
and Results of Operations filed under Item 7 and Note 2(a) of the Notes to
Consolidated Financial Statements filed under Item 8 of this report.

      Employees

      The total number of full-time employees for the system declined 8.2% to
2,217 in 1993 from 2,414 employees at year-end 1992 due to a second quarter
work force reduction.  Of the current total, 1,338 (60%) are represented by
various collective bargaining units.  Existing agreements are for varying
periods and expire in 1994 and thereafter.  Employee relations have generally
been satisfactory and management views the current work force level to be
appropriate to service the system's customers.

Item 2.  Properties

      The system's principal electric properties consist of Canal Unit 1, a
569 MW oil-fired steam electric generating unit, and its one-half ownership in
Canal Unit 2, a 580 MW oil-fired steam electric generating unit, both located
at Canal Electric's facility in Sandwich, Massachusetts.  Other electric
properties include an integrated system of distribution lines and substations
together with Commonwealth Electric's 60 MW steam electric generating station
located in New Bedford, Massachusetts.  This unit, which ceased operations in
October 1992, was abandoned in 1993.  As a result, the net book value of the
plant of approximately $4 million was reclassified from property, plant and
equipment to a regulatory asset in anticipation of future recovery.

      Cambridge Electric has two steam electric generating stations with a net
capability of 76.5 MW located in Cambridge, Massachusetts.  In addition, the
system has a 3.52% interest (40.5 MW of capacity) in Seabrook 1 and a 1.4% or
8.8 MW joint-ownership interest in Central Maine Power Company's Wyman Unit 4. 
The system also owns smaller generating units totaling 65.3 MW used primarily
for peaking and emergency purposes.  In addition, the system's other principal
properties consist of an electric division office building in Wareham,
Massachusetts and other structures such as garages and service buildings.
                                  PAGE 17

                        COMMONWEALTH ENERGY SYSTEM

      At December 31, 1993, the electric transmission and distribution system
consisted of 5,784 pole miles of overhead lines, 4,095 cable miles of under-
ground line, 359 substations and 371,594 active customer meters.

      The principal natural gas properties consist of distribution mains, ser-
vices and meters necessary to maintain reliable service to customers.  At the
end of 1993, the gas system included 2,739 miles of gas distribution lines,
151,192 services and 237,318 customer meters together with the necessary
measuring and regulating equipment.  In addition, the system owns a lique-
faction and vaporization plant, a satellite vaporization plant and above-
ground cryogenic storage tanks having an aggregate storage capacity equivalent
to 3.5 million MCF of natural gas.  The system's gas division owns a central
headquarters and service building in Southborough, Massachusetts, five
district office buildings and several natural gas receiving and take stations.

To Commonwealth Energy System:


    We have audited in accordance with generally accepted auditing standards,
the consolidated financial statements of Commonwealth Energy System appearing
in Exhibit A to the proxy statement for the 1994 annual meeting of
shareholders incorporated by reference in this Form 10-K, and have issued our
report thereon dated February 17, 1994.  Our audits were made for the purpose
of forming an opinion on those statements taken as a whole.  The schedules
listed in Part IV, Item 14 of this Form 10-K are presented for purposes of

auditing procedures applied in the audits of the basic financial statements
and, in our opinion, fairly state in all material respects the financial data
required to be set forth therein in relation to the basic financial statements
taken as a whole.

                                  May 5, 1994

To the Shareholders of
COMMONWEALTH ENERGY SYSTEM

      Notice is hereby given that the Annual Meeting of Shareholders of
Commonwealth Energy System will be held at the office of the System, One Main
Street, P.O. Box 9150, Cambridge, Massachusetts 02142-9150, on Thursday,
May 5, 1994, at 10:30 o'clock A.M., Eastern Daylight Time, for the following
purposes:

      1.    To elect three Trustees to hold office for a three-year term and
            until the election and qualification of their respective
            successors.

      2.    To take action on a proposal by the Board of Trustees to amend
            Section 22 of the System's Declaration of Trust, as amended,
            to revise the conditions under which presently authorized
            but unissued Common Shares of the System might be issued.

      3.    To approve the Long-Term Incentive Compensation Plan of
            Commonwealth Energy System and Subsidiary Companies.

      4.    To consider and vote upon a shareholder proposal, if presented at
            the meeting, as described herein.

      5.    To transact such other business as may properly come before the
            meeting or any adjournment or adjournments thereof.

      Common Shareholders of record at the close of business on March 18, 1994
are entitled to notice of, and to vote at, the meeting.

                                                By order of the Trustees,

                                                and General Counsel

April 1, 1994

                                   IMPORTANT

      We cordially invite you to attend the Annual Meeting of Shareholders,
but IF YOU DO NOT EXPECT TO BE PRESENT, PLEASE MAIL YOUR PROXY IN ORDER THAT
THE PRESENCE OF A QUORUM MAY BE ASSURED.  Because our shares are widely
distributed over a large number of holders, it is both necessary and desirable
that all Shareholders send in their proxies.  Failure to secure a quorum on
the date set would necessitate an adjournment, which would cause the System
considerable and needless expense.  To avoid this, please SIGN AND DATE the
accompanying proxy and mail it promptly in the enclosed envelope to Common-
wealth Energy System, P.O. Box 9150, Cambridge, Massachusetts 02142-9150.

                                PROXY STATEMENT

      This statement is furnished in connection with the solicitation of
proxies by the Board of Trustees of Commonwealth Energy System (hereinafter
called the "System") to be used at the Annual Meeting of Shareholders of the
System, to be held on Thursday, May 5, 1994, at the principal executive office
of the System, One Main Street, P.O. Box 9150, Cambridge, Massachusetts 02142-
9150, of which due notice has been given in accordance with the System's
Declaration of Trust dated December 31, 1926, as amended.  If the enclosed
form of proxy is executed and returned, it may nevertheless be revoked at any
time insofar as it has not been exercised.  A properly executed and returned
proxy will be voted in accordance with the directions contained thereon. 
Abstensions shall be voted neither "for" nor "against," but shall be counted
in the determination of a quorum.  Broker non-votes will not be counted either
in calculating the number of shares present for the purposes of determination
of a quorum or for the purposes of determining whether a matter has received
the required number of votes.  The giving of a later-dated proxy revokes all
proxies previously given.  The approximate date on which this Proxy Statement
and the accompanying proxy card will first be mailed to Shareholders is
April 1, 1994.

                             FINANCIAL STATEMENTS

      The audited financial statements of Commonwealth Energy System and
Subsidiary Companies, which include comparative Balance Sheets as of December

Accountants, are included in Exhibit A of this Proxy Statement.

      generally available are required to be disclosed in this column.  In
      1993, there were no such perquisites, earnings, reimbursements or
      discounts paid or made.

(3)   In 1993, the System did not provide to its employees, including
      Executive Officers, any form of restricted stock, stock options, stock
      appreciation rights, long-term incentive plan payouts or other forms of
      long-term compensation.

(4)   The amounts in this column represent the aggregate contributions by the
      System and certain subsidiary companies during 1993 on behalf of the
      above-named individuals to the Employees Savings Plan and/or the
      Executive Salary Continuation and Excess Benefit Plan of Commonwealth
      Energy System and Subsidiary Companies.  The Employees Savings Plan of
      Commonwealth Energy System and Subsidiary Companies is a defined
      contribution plan.  The Plan incorporates salary deferral provisions
      pursuant to Section 401(k) of the Internal Revenue Code for all
      employees who have elected to participate on that basis.  The Executive
      Salary Continuation and Excess Benefit Plan of Commonwealth Energy
      System and Subsidiary Companies is a defined contribution/defined
      benefit plan.  Unlike the Employees Savings Plan, this Plan is not a
      qualified plan under Section 401(a) of the Internal Revenue Code of
      1986.  The Plan was established to provide an additional benefit to any
      participant in the Employees Savings Plan whose benefit under the plan
      would be curtailed by limits in effect under the Internal Revenue Code
      for qualified plans.

(1)   Federal law places certain limits on the amount of benefits which can be paid
      from qualified pension plans.  Payments made by the System in excess of the
      applicable limitations are made pursuant to the terms of the Executive Salary
      Continuation and Excess Benefit Plan of Commonwealth Energy System and
      Subsidiary Companies.  For 1993, the maximum annual compensation limit under the
      Pension Plan for Employees of Commonwealth Energy System and Subsidiary
      Companies was $235,840, and the maximum annual benefit under that Plan was
      $115,641.
</TABLE>
      The Pension Plan for Employees of Commonwealth Energy System and
Subsidiary Companies is a non-contributory defined benefit plan.  The Plan is
a final average earnings type plan under which benefits reflect the employee's
years of credited service.  The employee receives the higher of either an
integrated or non-integrated Plan formula to realize the maximum retirement
benefit applicable to his or her employment history.  Both of the Plan
formulae are based on the average of the three highest consecutive January 1
base salaries during the ten-year period preceding the employee's retirement
or termination.  Retirement benefits are available to employees on or after
age fifty-five provided the sum of their age and years of service is at least
seventy-five.  Messrs. Poist, Wright, Margossian, Devanna and Sullivan have
29, 26, 24, 12 and 18 credited years of service respectively. 

      Each Executive Officer of the System has elected certain pre-retirement
death benefits and supplemental retirement benefits in exchange for waiving
certain standard life insurance benefits (in excess of $50,000), and the
survivor income benefits generally available to all eligible employees.  The
alternative program for Executive Officers provides a pre-retirement death
benefit of either:  (i)  a lump-sum payment of three times salary; or (ii) 
fifty percent of monthly base salary for one hundred and eighty months.  The
supplemental retirement benefit provides that an Executive Officer may retire
after the attainment of age fifty-five and completion of ten years of service. 
Normal retirement at age sixty-five provides an annual payment equal to
thirty-five percent of final base salary per year for life, or for a period of
                                    PAGE 9


one hundred and eighty months, whichever is longer.  Benefits are reduced for
retirement prior to age sixty-five.  The supplemental retirement benefits are
in addition to the amounts shown in the table above and are not subject to
limitation. If the employment of the Executive Officer shall terminate for any
reason other than death and before completion of ten years of service and
attainment of age fifty-five, there are no benefits payable under this
alternative program for Executive Officers.

            COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

      The Executive Compensation Committee of the Board of Trustees has
furnished the following report on executive compensation for 1993:

      Compensation for the Chief Executive Officer, as well as for the named
Executive Officers, consists of base salary plus annual variable incentive
compensation of up to 30% of base salary, which is awarded if certain
designated performance criteria are achieved.  The Executive Compensation
Committee has developed this compensation package in order to motivate
executive performance, enhance the profitability of the System and maximize
shareholder value.

      The Chief Executive Officer's base compensation is determined by review
of comparative salary data and by evaluation of certain performance criteria.
The Executive Compensation Committee performs periodic comparisons of
executive compensation at other similarly sized utility companies. 
Comparative data has been provided by external consulting services, the
System's human resource department and by reference to information provided by
industry sources such as the Edison Electric Institute.  Base salary has been
continually reviewed and is adjusted to reflect the competitive market and the
performance of the Chief Executive Officer, as judged by the Executive
Compensation Committee on a subjective basis through the evaluation of
objective criteria.

      The Chief Executive Officer's award for 1993 pursuant to the System's
Annual Incentive Plan (the "Plan"), as hereinafter described, was determined
on a weighted basis, with two-thirds of the award potential attributable to
the attainment of System goals and objectives, and one-third of the award
potential attributable to individual goals and objectives.  For 1993, the
System criteria forming the goals and objectives applicable to the Plan were:
1) total shareholder return as measured by stock appreciation plus dividend
rate and as compared to a representative peer group of investor-owned public
utilities as provided by Duff & Phelps Investment Research Co.; 2) success in
implementing budgetary constraints in the interest of controlling costs; and
3) meeting certain pre-established benchmark measures of operation and
maintenance expenses per customer, as compared to a peer group of 19 companies
chosen by the System's compensation consultant.  Each of the three System
goals and objectives are equally weighted, and awards are made based on
meeting, exceeding or reaching maximum attainment of targets.  The goal
established for total shareholder return was to meet or exceed the average
return for the peer group.  The System realized a return of 15.25% in 1993,
compared to an industry peer group average of 9.46%, which resulted in the
maximum award as a result of exceeding the maximum target of 10% over the
industry peer group average.  The goal established for cost control was for
operating and maintenance expenses in 1993 to be below the approved budgeted
amounts.  This goal was achieved by the System having reduced actual operation
and maintenance expenses to 7.1% below established budgets, resulting in a
maximum award for having exceeded the 5% below budget maximum target.  The
goal of maintaining operating and maintenance expenses per customer within the
top 50% of the 19 company industry peer group was exceeded.  The System was
rated eighth out of nineteen companies in the peer group.  In the aggregate,
the goals and objectives applicable to the System component of the Plan were
rated as 92% achieved.
                                    PAGE 10


      The individual goals of the Chief Executive Officer for 1993 included: 
organizational change relating to subsidiary operations, System strategic
planning documentation, improved regulatory relations, and the development of
an incentive award plan to align shareholder and management interests.  The
Chief Executive Officer's performance relative to achieving individual goals
was rated as 85% achieved, resulting in an aggregate performance rating of
89.7% achievement.

      With respect to other Executive Officers, the Chief Executive Officer,
in conjunction with the System's human resources staff, established salary
ranges for each Executive Officer.  The salary ranges were based in part upon
salaries provided to executive officers in the System's industry peer group, 
as reported by the Edison Electric Institute and from regional salary surveys
so as to establish salary ranges generally in the median of the peer group. 
Specific salary levels were then established through an evaluation of the
Executive Officer's performance of goals and duties, including goals relating
to earnings levels and return on equity.  The base salary levels, as
recommended by the Chief Executive Officer, were also reviewed and approved by
the Executive Compensation Committee.

      In addition to base salary, the named Executive Officers are also
eligible under the Plan to receive annual variable incentive compensation of
up to a maximum of 30% of annual base salary.  In 1993, the System goals and
objectives constituting the annual performance criteria and the corresponding
weightings which determined eligibility for awards to the named Executive
Officers under the Plan were the same as those applicable to the Chief
Executive Officer.  The individual goals and objectives of the other Executive
Officer Plan participants included various financial and operating performance
standards, such as the successful completion of debt and equity financings of
certain of the System's subsidiaries, and the maintenance of individual
department total annual expenses at amounts not exceeding approved budgets.

               MEETINGS OF THE BOARD OF TRUSTEES AND COMMITTEES

      The System's Board of Trustees held thirteen meetings throughout 1993. 
The Board has an Audit Committee, an Executive Compensation Committee, a
Nominating Committee and a Benefit Review Committee.

      The Audit Committee is composed of Betty L. Francis, Chairperson, and
Sinclair Weeks, Jr.  The Committee held four meetings in 1993.  The
Committee's functions are:  to recommend the selection of an independent
public accountant; to review the scope of and approach to audit work; to 
review non-audit services provided by the independent public accountants; and
to review accounting principles and practices and the adequacy of internal
controls.

      The Executive Compensation Committee is composed of Henry Dormitzer,
Chairperson, Sheldon A. Buckler and Gerald L. Wilson.  During 1993 the
Committee held four meetings.  The Committee was formed for the purpose of
reviewing and recommending compensation and promotional adjustments for
certain of the System's personnel.

      The Nominating Committee is composed of Sinclair Weeks, Jr.,
Chairperson, Franklin M. Hundley and Sheldon A. Buckler.  The Committee held
four meetings in 1993.  The functions of the Committee are:  to coordinate 
                                    PAGE 13

the Board of Trustees nominees for vacancies occurring from time to time on
the Board of Trustees.  The Committee will consider nominees recommended by
Shareholders upon the timely submission of the names of such nominees with
their qualifications and biographical information forwarded to the Nominating
Committee of the Board of Trustees.

      The Benefit Review Committee is composed of Franklin M. Hundley,
Chairperson, Henry Dormitzer and Gerald L. Wilson.  During 1993 the Committee
held two meetings.  The Committee was organized to consider and recommend to
the Board of Trustees matters associated with the System's major funded
benefit plans.  Functions of the Committee include:  recommending the
composition of benefit plan boards and reviewing investment policy,
objectives, performance or proposed changes related to the plans.

      Each Trustee who was not an employee of the System is compensated for
his or her services as Trustee at the rate of $10,000 per annum, plus $750 for
each Trustee and Committee meeting attended.  The Chairpersons of the Audit,
Executive Compensation and Benefit Review Committees each receive an
additional $1,000 during the year.  In addition, the Chairman of the Board
receives a retainer of $10,000 per annum for his services as Chairman of the
Board and of the Nominating Committee.

      The Retirement Plan for Trustees of Commonwealth Energy System was
adopted to provide retirement benefits to non-management members of the Board
of Trustees in recognition of their services to the System.  Members of the
Board of Trustees who have served as Trustees for at least five years are
eligible to participate in the Plan.  Each eligible Trustee qualifies for an
annual retirement benefit payment equal to fifty percent of the annual
retainer fee in effect at retirement (excluding retainers for chairing
committees), plus 10% of the annual retainer fee for each year in addition to
five years served, up to 100% of such fee.  The annual retirement benefit
payment is adjusted to reflect the first subsequent increase, if any, in the
annual retainer fee for service on the Board following the Trustee's
retirement.  The annual retirement benefit payment becomes vested at the time
of eligibility and will be payable to Trustees for a period of ten years.

             2-AMENDMENT TO SECTION 22 OF THE DECLARATION OF TRUST

      There will be presented to Shareholders by the Board of Trustees a
proposal to consent to an amendment to Section 22 of the System's Declaration
of Trust, which Section sets forth the conditions under which presently
authorized but unissued Common Shares of the System may be issued by the 
Trustees without the vote or written consent of a majority of the Common
Shares outstanding at the time.  The purposes of the amendment are to expand
the conditions under which such presently authorized but unissued Common
Shares may be issued without the vote or written consent of a majority of the
Common Shares outstanding at the time, and to also delete some of the existing
conditions under which such authorized but unissued shares may be issued, due
to the fact that certain events which have occurred in the last ten years make
such provisions no longer applicable.  The text of the proposed amendment to
Section 22 is annexed as Appendix A to this Proxy Statement.
                                    PAGE 14


      The proposed amendment to Section 22 would allow for the issuance of
Common Shares to fund long-term compensation plans which might be adopted by
the Board of Trustees from time to time. The Trustees believe that such
amendment would be in the interests of Shareholders, as it will enable the
System to attract and retain qualified employees and will provide to such
employees further incentive to maximize shareholder value for the benefit of
Shareholders.  Under the terms of the Commonwealth Energy System and
Subsidiary Companies Long-Term Incentive Compensation Plan, which Shareholders
are being requested to approve pursuant to Item 3 of this Proxy Statement, no
issuance of Common Shares will be made to employees until certain benchmarks,
set to require that Shareholders' interests have first been protected, have
been met.  The Board of Trustees believes that the Long-Term Incentive
Compensation Plan will provide key employees with greater incentive and that
it will enable the System to attract and retain highly qualified executives
and other key employees in the future, and will advance the operational and
financial interest of the System by better aligning the interests of key
employees with the interests of Shareholders.

      The required approval by Shareholders to the proposed amendment and the
subsequent enactment of the Long-Term Incentive Compensation Plan will allow
the System to continue to employ and to keep in employment valuable employees
who will continue to advance the interests of Shareholders.

      With respect to the proposed amendment which eliminates the references
to Algonquin Energy, Inc. in subparagraphs 3 and 4 of the third paragraph of
Section 22 of the Declaration of Trust, such elimination simply reflects the
sale by the System of its interest in Algonquin Energy, Inc. in 1986.

      Upon the consent of the holders of a majority of the outstanding Common
Shares present at the meeting and entitled to vote on the proposed amendment,
the Trustees of the System will on May 5, 1994 vote to amend the Declaration
of Trust and will file said Declaration of Trust, as amended, as required by
the terms of the Declaration of Trust and the laws of the Commonwealth of
Massachusetts.

      THE TRUSTEES RECOMMEND A VOTE "FOR" THE APPROVAL OF THE AMENDMENT.

                    3-LONG-TERM INCENTIVE COMPENSATION PLAN

      On February 16, 1994, the Board of Trustees approved and adopted the
Commonwealth Energy System and Subsidiary Companies Long-Term Incentive
Compensation Plan ("Incentive Plan") for key employees of the System and its
subsidiaries.  Since the Incentive Plan awards are to be paid in the form of
System Common Shares, the Board of Trustees is seeking Shareholder approval of
the Incentive Plan and has conditioned adoption of the Incentive Plan on
Shareholder approval.

      The following is a summary of the principal features of the Incentive
Plan.  The summary is qualified in its entirety by reference to the complete
text of the Incentive Plan, which is attached to this Proxy Statement as
Appendix B.

      The Incentive Plan is intended to compensate the System's key employees
based upon performance standards and objectives and to reward performance with
Share ownership in the System so that key employees have a greater proprietary
interest in the System.  The Incentive Plan will provide for competitive,
market-based total compensation for key employees comprised of base salary 
                                    PAGE 15


plus incentive salary, including Common Shares issued to such key employees
under the Incentive Plan that is at risk.  The Board of Trustees believes that
the Incentive Plan will provide key employees with greater incentive and that
it will enable the System to attract and retain highly qualified executives
and other key employees in the future, and will advance the operational and
financial interest of the System by better aligning the interests of key
employees with the interests of Shareholders.

      An Incentive Plan Period shall have a three year term, with the first
Plan Period commencing on January 1, 1994.  The Incentive Plan will be
administered by members of the Executive Compensation Committee of the Board
of Trustees, none of whom may participate in the Plan.  The Executive
Compensation Committee will have full authority to interpret and administer
the Incentive Plan, including the authority to determine the key employees who
will participate in the Incentive Plan and the performance standards that will
be used to determine the amounts of Incentive Awards that can be earned under
the Incentive Plan.  No Incentive Award shall be made by the Executive
Compensation Committee without the prior approval of a majority of the members
of the Board of Trustees of the System who at the time are ineligible to
participate in the Plan.  Awards under the Plan may be made until February 16,
2003.

      The Incentive Plan provides that key employees designated by the
Executive Compensation Committee can earn a portion of their compensation
("Incentive Awards") based upon total Shareholder return criteria as set from
time to time by the Executive Compensation Committee.  No Incentive Awards are
earned under the Incentive Plan unless certain Shareholder success criteria
are met with respect to total Shareholder return.  In addition, no Incentive
Awards will be earned if the System's average return on equity for any Plan
Period does not achieve at least 80 percent of the target return over the
performance period.

      The System's Chief Executive Officer, the presidents of the System's
operating companies, all vice presidents of the System's subsidiary companies
and certain other senior management employees designated by the Executive
Compensation Committee are eligible to participate in the Incentive Plan.

      Incentive Awards are established for each Plan Period for Incentive Plan
participants and are calculated as a percentage of the employee's annual base
salary as of January 1 at the beginning of the Plan Period.  For the initial
Plan Period, the Incentive Awards range up to 50% of salary for Messrs. Poist,
Wright and Margossian and up to 40% of salary for the 11 vice president
participants, including Messrs. Devanna and Sullivan.  The initial shareholder
category Incentive Award standards, which use the same Peer Group Index used
to compare total shareholder return of the System's Common Shares as described
on page 7 in this Proxy Statement, and the Incentive Award Potentials for the
initial Plan Period are as follows:

                      Shareholder Total Return Standards

            Threshold              Plan Target               Maximum

      95% of Index Average      Index Average       120% above Index Average


                          Incentive Award Potentials

                                              Plan
      Participant             Threshold      Target      Maximum

      CEO and Operating
        Company Presidents      16.5%         33.5%        50.0%

      Vice Presidents           13.0          27.0         40.0
                                    PAGE 16


      Incentive Awards shall be awarded in the form of the System's Common
Shares ("Grant Shares").  The number of Common Shares awarded will be based on
the average market price of the System's Common Shares during the first five
trading days of the February following the close of the Plan Period.  Provided
that the amendment to the System's Declaration of Trust hereinbefore described
is approved, the Common Shares which are awarded may be directly issued to the
Incentive Plan participants.  The maximum number of Common Shares in respect
for which Grant Shares may be cumulatively granted under the Incentive Plan,
subject to adjustment as provided in Paragraph 11 of the Incentive Plan,
during the term in which the Incentive Plan is effective, shall be one percent
(1%) of the total issued and outstanding Common Shares of the System.

      Shares awarded will be subject to forfeiture to the System and cannot be
transferred for a period of three years from the date of each Incentive Award. 
Such forfeiture will generally occur on termination of employment within the
three-year period.  The three-year forfeiture and non-transferability period
will terminate automatically in the event of death, disability, or a change in
control as defined in the Incentive Plan, or, at the Executive Compensation
Committee's discretion upon normal retirement.  During such three-year period,
Incentive Plan participants will own the Shares awarded and will have the
right to vote such Shares and receive dividends and other distributions. 
Participants will generally be subject to federal income taxation on receipt
of Shares awarded in the year in which the three-year forfeiture and non-
transferability periods lapse, based upon the market value at the date of
lapse.

      Reference is made to "Executive Compensation," pages 4 through 7 above,
for information regarding various other employee benefit plans and agreements
of the System.  None of the prospective Executive Officer participants in the
Incentive Plan received any payments or distributions during the last three
fiscal years, other than salary and cash compensation pursuant to the employee
benefit plans and agreements described on pages 4 and 5 in this Proxy
Statement, and annual incentive compensation earned and awarded to the persons
and in the amounts set forth on page 4 of this Proxy Statement.

      The adoption of the Incentive Plan will require the affirmative votes of
the holders of a majority of the Shares present at the meeting and entitled to
vote.  If approved by the Shareholders, the Incentive Plan will be effective
for the System's 1994 fiscal year.

      THE TRUSTEES RECOMMEND A VOTE "FOR" THE ADOPTION OF THE LONG-TERM
INCENTIVE COMPENSATION PLAN.

                            4-SHAREHOLDER PROPOSAL

      The System has been advised that Mr. John Jennings Crapo, Porter Square
Branch, P.O. Box 151, Cambridge, Massachusetts, 02140-0002, holder of 225
Common Shares, proposes to submit the following proposal at the 1994 Annual
Meeting:

      RESOLVED: That the Shareholders of Commonwealth Energy System assembled
in Annual Meeting of Shareholders balloting in person and by Proxy hereby
request that the Board of Trustees present to shareholders at the next Annual
Meeting of Shareholders an appropriate amendment to the DECLARATION OF TRUST,
dated December 31, 1926, as amended, to provide that at any elections
following the adoption of the said amendment, Trustees whose terms have
expired be elected annually and not by classes as is now provided.
                                    PAGE 17


      SUPPORTING STATEMENT:  The Proposal received enough votes at the May 06,
1993 Annual Meeting of Shareholders to be considered again, so ruled System
Chief Executive Officer, the Honorable President William G. Poist.  The vote
was announced at the meeting and in compliance with my request at said
meeting, System Vice President, General Attorney, and Secretary, Mr. Michael
P. Sullivan, Esquire, sent me by mail a written report of the vote concerning
the Proposal.

The vote was this way:

1,689,952 Common Shares or 16.9% were voted "For" the Proposal
5,726,876 Common Shares or 56.2% were voted "Against" the Proposal
288,974 Common Shares or 2.8% "Abstained" from the Proposal.
Mr. Vice President added 'As a result and in accordance with the applicable
regulations you are entitled to bring forth your proposal at the 1994 Annual
Meeting of Shareholders.'

The Board of Trustees have continued to offer very persuasive arguments in
behalf of retaining the staggered system of electing Trustees, to such an
extent I had begun to think maybe I had the wrong idea on the matter.  I
offered a Proposal to a New England utility to institute at it classified
elections of Trustees.  Due to slow mail the Proposal didn't arrive in time to
be considered timely but an official of that utility assured me January 21,
1993, in his letter, that the directors at that company 'keep informed of 
developments that could have an adverse impact on our shareholders' best 
interest.'  I was alarmed that mutual funds could take the utility over and he
said the company is regulated under the Public Utility Act of 1935 and under
that Act a person or company must obtain the approval of the SEC to acquire 5%
or more of the voting stock of a public utility holding company.  In addition,
if a person or company owns more than 10% of the voting stock, it becomes
subject to regulation as a public utility holding company.  Few companies,
other than utilities, would want to subject themselves to such rigorous
regulation.'

We're all stockholders, not just the Trustees, so I feel we all have a right
to decide this and our System Trustees should offer us additional arguments as
to why we shouldn't reinstitute annual elections to all Trustees.

      BOARD OF TRUSTEES RECOMMENDATION:

      The Board of Trustees recommends a vote AGAINST this proposal for the
      following reasons:

      This proposal has been submitted at each Annual Meeting since 1991.  It
requests that the Board of Trustees submit a proposal to Shareholders at the
1995 Annual Meeting, calling for the repeal of the classified Board, so that
all Trustees would be elected on an annual basis.  The classified board was
adopted at the 1987 Annual Meeting, when Shareholders voted to amend the
System's Declaration of Trust to create three classes of Trustees, with an
equal number of Trustees in each class, and to provide that the Trustees would
serve three year staggered terms, such that three Trustees are eligible for
election each year.  The classified Board is intended to help to assure
continued familiarity of Board members with the business, management and
policies of the System, since a majority of the Trustees at any given time
would have prior experience as Board members.  These amendments are also
designed to encourage persons seeking to acquire control of the System to
initiate an acquisition through arms-length negotiations with the System's
management and Board of Trustees, by making it more difficult to change the
composition of the Board.  Also, the amendments may allow the System's
management to obtain more time and information for evaluating a takeover
proposal, in order to fully protect the interests of the System and its
Shareholders.
                                    PAGE 18


      The Board believes that each Trustee is fully accountable to
Shareholders throughout each term of office, whether that term is three years
or one year.  The Board further notes that the classified Board system was
determined to be of sufficient merit such that the Massachusetts legislature
has codified that system, in its 1990 amendments to the laws pertaining to
Massachusetts business corporations (however, the System, as a Massachusetts
Trust, is not affected by this legislation).

      Repeal of the classified Board (which, if the present proposal is
adopted, would actually be pursuant to the acceptance of a proposed Amendment
to the Declaration of Trust to be offered at the 1995 Annual Meeting of
Shareholders) requires the affirmative vote or written consent of three-
quarters of the shares entitled to vote (by the terms of the System's
Declaration of Trust).

          ACCORDINGLY, A VOTE "AGAINST" THE PROPOSAL IS RECOMMENDED.

                               5-OTHER BUSINESS

      The Board of Trustees of the System knows of no matters other than those
set forth in the Notice of the Annual Meeting which are likely to be brought
before the meeting.  However, if any other matters of which the Board of
Trustees is not aware are appropriately presented for action, it is the
intention of the persons named in the proxy to vote in accordance with their
judgment on such matters.

                                 MISCELLANEOUS

      The independent public accounting firm selected by the Trustees as
Auditor of the System is Arthur Andersen & Co.  It is expected that
representatives of Arthur Andersen & Co. will be present at the Annual Meeting
with the opportunity to make a statement if they desire to do so and to
respond to appropriate questions.

      The cost of soliciting proxies will be borne by the System.  A limited
number of regular employees may solicit proxies by telephone or in person
subsequent to the initial solicitation by mail.  In addition, the System has
retained the firm of D. F. King to aid in such solicitation of proxies.  The 
System expects to pay such firm a fee of $5,000 plus expenses.  The System
will reimburse banks, brokerage firms and other custodians, nominees and
fiduciaries for reasonable expenses incurred in sending proxy material to
security owners.

      The proxy card for a participant in the System's Dividend Reinvestment
and Common Share Purchase Plan includes the number of shares which are
registered in the participant's name and the number of shares beneficially
owned by the participant that are held in the name of the nominee of the
System for the Plan.  A participant's vote with respect to the shares
registered in the participant's name is also an instruction by the participant
to the nominee to vote the shares credited to the participant's account under
the Plan.

      In order for Shareholder proposals for the 1995 Annual Meeting of
Shareholders to be eligible for inclusion in the System's Proxy Statement,
they must be received by the System at its principal office in Cambridge,
Massachusetts, prior to December 2, 1994.
                                    PAGE 19


      It is important that proxies be returned promptly to avoid unnecessary
expense.  Therefore, Shareholders are urged, regardless of the number of
shares owned, to SIGN, DATE and RETURN the enclosed proxy promptly.

                             PROPOSED AMENDMENT TO
                    SECTION 22 OF THE DECLARATION OF TRUST



      Section 22 of the System's Declaration of Trust would be amended (1) by
deleting subparagraph (A)(3), which contains the words "to acquire additional
stock of Algonquin Energy, Inc.;" (2) by deleting in the second line of the
existing subparagraph (A)(4) the words "of Algonquin Energy, Inc., or" and (3)
by adding the following new subparagraph (C) "To provide Common Shares to fund
long-term incentive compensation plans that may be adopted from time to time",

      so that the third paragraph of Section 22 reads in its entirety, as
follows:

      (A)   To provide the System with Funds
            (1) To acquire additional stock of any subsidiary of the 
      System which is authorized for its proper corporate purposes;
            (2) To acquire common stock of any Massachusetts gas or
      electric company if as a result of such transaction the System
      will own 51% or more of such stock;
            (3) To acquire debt securities maturing more than one year
      from the date of issue thereof of any subsidiary of the System;
            (4) To retire temporary indebtedness of the System incurred
      by it for the purchase of such stock or debt securities; or
            (5) To make temporary advances to any subsidiary of the
      System; or

      (B)   In Exchange
            (1) For publicly held stock of any subsidiary of the System;
      or
            (2) For stock of any Massachusetts gas or electric company
      if as a result of such exchange the System will own 51% or more
      of such stock; or

      (C)   To provide Common Shares to fund long-term incentive compensation
      plans that may be adopted from time to time.

                                                            APPENDIX B


                          COMMONWEALTH ENERGY SYSTEM
                           AND SUBSIDIARY COMPANIES

                     Long-Term Incentive Compensation Plan


 1.   Purpose.  The purpose of this Plan is to advance the interests 
      of Commonwealth Energy System (the "System") by providing
      long-term financial incentives to selected key employees of
      the System and its subsidiaries for achieving specified
      objectives.  The Plan is designed to recognize and reward
      success relative to Plan objectives and permit participants
      to acquire Common Shares of the System ("Shares").  By 
      encouraging such share ownership, the System seeks to 
      attract, retain and motivate employees of experience, 
      ability and quality and to strengthen the mutuality of
      interests between such key employees and the System's
      common shareholders.

 2.   Plan Term.  The Plan became effective on February 16, 1994,
      (the "Effective Date"), the date it was adopted by the Board
      of Trustees of the System, provided the Plan is approved by
      common shareholders at the next annual meeting of shareholders
      of the System following the Effective Date.  If such approval
      is not granted, the Plan shall become null and void.  Awards
      under the Plan may be granted through February 16, 2003.

 3.   Administration.
      (a)   The Plan shall be administered by the Executive
            Compensation Committee of the Board of Trustees of
            the System (the "Committee").  The members of the
            Committee shall not be eligible to participate in
            the Plan and shall be disinterested persons as
            defined in Rule 16(b)-3(c) under the Securities
            Exchange Act of 1934 (the "Exchange Act").  
            Subject to the provisions of the Plan, the 
            Committee shall have full power to construe and 
            interpret the Plan and to establish, amend and 
            rescind rules and regulations for its administration.  
            The interpretation and construction by the 
            Committee of any provision of the Plan or an 
            award ("Incentive Award") granted pursuant to the 
            Plan and any determination by the Committee 
            pursuant to any provision of the Plan or any 
            such Incentive Award shall be final and conclusive, 
            and binding on both the Participant (as defined in 
            paragraph 4) and the System.  All Incentive Awards
            shall be made in the form of Shares ("Grant Shares").
            Notwithstanding the foregoing or any other
            provision of the Plan, no Incentive Award shall be
            made by the Committee without the prior approval of
            a majority of the members of the Board of
            Trustees of the System who at the time are ineligible
            to participate in the Plan and who are disinterested
            persons as defined in Rule 16(b)-3(c) under the
            Exchange Act.
                                    PAGE 22


      (b)   The Committee shall hold meetings at such times and
            places as it may determine.  A majority of members
            of the Committee shall constitute a quorum and
            actions approved by a majority of the members of
            the Committee at a meeting at which there is a
            quorum, or actions approved in writing by a
            majority of the members of the Committee, shall
            be valid actions of the Committee.

 4.   Eligible Employees.  Participants in the Plan shall comprise
      such key employees of the System or of any of its subsidiaries
      (including members of the Board of Trustees who are also
      employees of the System or any of its subsidiaries) as
      are selected by the Committee from time to time (any such
      selected employee being referred to as a "Participant").
      To be eligible for a Grant Share award, the designated 
      employee must be an officer or other senior employee who 
      holds a position of significant responsibility.  Grant 
      Shares shall consist of restricted Shares of the System 
      and shall be subject to the provisions of this Plan.

 5.   Shares Subject to the Plan.  The maximum number of Grant 
      Shares which may be cumulatively granted under the Plan, 
      subject to adjustment as provided in Paragraph 11 of the 
      Plan, during the term in which the Plan is effective, 
      shall be one percent (1%) of the total issued and 
      outstanding Shares.  Any Grant Shares which are forfeited 
      pursuant to paragraph 9 (g)(i) shall again be eligible 
      for issuance.

 6.   Incentive Awards.
      (a)   Incentive Award Potential.  A Plan Period shall 
            be three years, commencing on January 1 and 
            terminating on the December 31 occurring two 
            years after the year in which the period commenced.
            The first Plan Period shall commence on January 1, 
            1994 and conclude on December 31, 1996.  No Plan
            Period shall commence in 1995.  The second Plan 
            Period shall commence on January 1, 1996, and 
            conclude on December 31, 1998.  The Committee, in its 
            sole discretion, may amend or modify the commencement 
            and duration of Plan Periods.

            As soon as practicable during each Plan Period, the 
            Committee shall (i) designate those individuals who 
            are to be Participants hereunder in the Plan for such 
            Plan Period, (ii) assign each such Participant a 
            level of participation in the Plan for such Plan Period 
            and (iii) establish for each level of participation 
            the threshold, target and maximum Incentive Award 
            Potential, expressed in each case as a percentage of 
            the Participant's annual base salary as of January 1 
            at the beginning of the Plan Period.  The Incentive 
            Award Potentials for the Participants in the Plan 
            for the Plan Period terminating December 31, 1996, 
            (Plan Period 1994), are set forth in Table 1 below.

            Incentive Award potentials applicable to levels of
            participation in the Plan for Plan Periods subsequent 
            to 1994 shall be established by the Committee from 
            time to time as provided above.

                        1994 Incentive Award Potentials
                     (Plan Period 1-1-94 through 12-31-96)

      Vice Presidents          2       13.0       27.0       40.0

            The amount of each Participant's actual Incentive 
            Award (if any) hereunder will depend upon the System's 
            achievement of specified performance criteria set 
            forth in subparagraph (b) below and subject to the
            satisfaction of the provisions of paragraph 8.

      (b)   Performance Evaluation.  The Committee shall evaluate 
            the System's performance relative to a specified 
            shareholder success criterion for the three years 
            comprising a Plan Period.  For the 1994 Plan Period, 
            the shareholder success criterion shall be the System's 
            three-year average shareholder total return results 
            (share appreciation and dividends) compared to the 
            Peer Group Index of utility companies published by 
            Value Line, Inc.

            The Committee shall establish performance standards 
            for each Plan Period in such a manner as to promote
            achievement of meaningful total return results.  Three
            levels of performance standards shall apply and be set 
            by the Committee.  Except in the 1994 Plan Period, the 
            three levels of performance standards shall be set 
            prior to the onset of a Plan Period.  For the 1994 Plan 
            Period, the shareholder total return standards are set 
            forth in Table 2.

                                    TABLE 2
                               1994 Plan Period

                                    PAGE 24


            If the System's performance for any Plan Period 
            results in its achieving the Threshold, Plan Target 
            or Maximum performance standard, the earned Incentive 
            Award shall be determined by the levels set forth in 
            Table 1.  If achieved results fall between the 
            Threshold, Plan or Maximum performance standards, the 
            Incentive Award shall be determined by interpolation.  
            If performance falls below the Threshold, there will 
            be no Incentive Award.

 7.   Discretionary Incentive Awards.  In addition to Incentive Awards
      pursuant to paragraph 6 hereof, the Committee may, in its sole
      discretion, make an Incentive Award with respect to a Plan
      Period to an employee of the System who, upon recommendation
      by the System's Management Committee, is deemed to be an
      exceptional performer.  The maximum discretionary Grant Share
      Award hereunder for a Plan Period to any Participant who is not
      an officer may not exceed 10% of such Participant's annual base
      salary as of January 1 at the beginning of the Plan Period.
      All such Incentive Awards shall also be subject to the provisions 
      of paragraph 8.

 8.   Shareholder Protection.  No grant of an Incentive Award
      shall be made for any Plan Period in which the System's 
      average return on equity does not achieve at least 80 
      percent of the target return over the performance period 
      as established by the Committee.

 9.   Terms and Conditions of Grant Shares.  Grant Shares may
      be issued pursuant to the Plan and shall be subject to
      the following terms and conditions:

      (a)   Price.  Grant Shares shall be issued in consideration
            of services rendered by the Participant.

      (b)   Number of Shares.  The number of Grant Shares
            issued to each Participant, if any, shall be
            determined by dividing the amount of a Participant's
            Incentive Award or the Committee's discretionary 
            award of Grant Shares by the average closing price
            for the Shares on the principal national securities 
            exchange on which the Shares are listed or admitted 
            to trading on the first five (5) trading days of 
            the February following the close of the Plan Period.
            Fractional Shares shall be rounded up or down to 
            whole Shares.

      (c)   Match Shares.  The Committee shall award any
            Participant who accumulates a Grant Share balance
            equal in value to 100 percent of the Participant's
            base salary an additional award of Grant Shares
            in an amount equal to 10 percent of the Participant's
            base salary in effect on January 1 during the year 
            during which the 100 percent value is realized.  Grant
            Share balance shall mean the cumulative total of 
            all Grant Shares issued and retained exclusive of 
                                    PAGE 25


            the present award.  The number of Grant Shares 
            awarded shall be found by dividing the award value 
            of 10 percent of the Participant's base salary by 
            the average closing price of the Shares on the 
            principal national securities exchange on which 
            the Shares are listed or admitted to trading on 
            the first five (5) days of the February following 
            the close of the Plan Period.  Each succeeding 
            25 percent of base salary held as Grant Shares 
            in addition to the 100 percent value shall be 
            similarly matched by an additional award of Grant 
            Shares at the rate of five (5) percent 
            of base salary.

      (d)   Forfeiture of Grant Shares.  Grant Shares issued
            under this Plan shall be subject to forfeiture as
            specified in paragraph 9 (g)(i).

      (e)   Non-Transferability.  To the extent that any Grant
            Shares remain subject to the forfeiture provisions
            of paragraph 9 (g)(i), they shall be non-transferable
            by the Participant and may not be pledged,
            hypothecated or otherwise encumbered.  

      (f)   Withholding Taxes.  At the time that the interest of
            a Participant in Grant Shares vests and as a condition
            of the System's obligation to deliver a certificate
            for such Grant Shares to the Participant, the
            Participant shall pay to the System an amount equal
            to all taxes required to be withheld by the System
            for the account of the Participant as a result
            of such issuance; or, in lieu of such payment, the
            System may, at its sole option, accept the written
            authorization of the Participant to withhold such
            taxes from compensation thereafter becoming
            payable to the Participant by the System.  If the
            Participant shall elect under Section 83 of the
            Internal Revenue Code of 1986, as amended, to
            accelerate the recognition of income attributable
            to the receipt of Grant Shares, the Participant
            shall furnish the System with a copy of such election
            concurrently with its filing with the Internal
            Revenue Service and shall pay the System the amount
            of taxes required to be withheld for the account
            of the Participant by reason of such election.

      (g)   Vesting.
            (i)   The interest of a Participant in Grant Shares
                  shall vest on the date three (3) years from
                  the date such Grant Shares were issued to
                  the Participant, except as provided in
                  subparagraph (ii), below, provided that the
                  Participant shall have remained employed by
                  the System one of its subsidiaries during the 
                  three-year period immediately following the 
                  date the Grant Shares were issued to the 
                  Participant.  If the Participant fails to 
                  complete such three-year employment requirement 
                                    PAGE 26


                  and his or her interest in the Grant Shares is 
                  not otherwise vested under subparagraph (ii), 
                  below, the Participant shall forfeit to the 
                  System all unvested Grant Shares theretofore 
                  issued to such Participant and the Participant 
                  shall thereafter have no further rights with
                  respect to such Grant Shares.

            (ii)  Notwithstanding the foregoing, a Participant's
                  interest in Grant Shares may become vested
                  at a date earlier than three years from the
                  date of issue for such reasons as may be
                  specified by the Committee, in its sole discretion
                  at the time of or subsequent to an award of
                  Grant Shares and shall become immediately
                  vested upon any one of the following occurrences:

                  (A)   The Participant's employment by the System
                        or any of its subsidiaries terminates by
                        reason of such Participant's death or
                        disability (as defined in Section 72(m)(7)
                        of the Internal Revenue Code of 1986, as
                        amended); or

                  (B)   There is a "change in control" of the
                        System.  For the purposes of this Plan, a
                        "change in control" shall mean the occurrence
                        of any of the following:
                        (1)   The System receives a report on
                              Schedule 13D filed with the Securities
                              and Exchange Commission disclosing that 
                              any person (as such term is defined in 
                              Section 13(d) of the Exchange Act), group, 
                              partnership, association, corporation or 
                              other entity is the beneficial owner, 
                              directly or indirectly, of 20% or more 
                              of the outstanding voting Common Shares of
                              the System (other than: 1) a registered
                              investment company which has expressly
                              stated that it has no intention to
                              acquire control of the System or which
                              the Committee has determined that such
                              registered investment company has no
                              intention to acquire control of the
                              System and 2) the Employees Savings
                              Plan of Commonwealth Energy System and
                              Subsidiaries); provided that if the
                              Committee subsequently determines that
                              such registered investment company does
                              intend to acquire control of the System
                                    PAGE 27


                              or the registered investment company
                              expresses this intent, the beneficial
                              ownership of 20% or more of the outstanding
                              voting Common Shares of the System shall
                              be considered to be a "change in
                              control" event described in this
                              clause (1);

                        (2)   Any person (as such term is defined in
                              in Section 13(d) of the Act), group,
                              partnership, association, corporation 
                              or other entity other than the System
                              or a wholly-owned subsidiary of the
                              System, purchases Shares pursuant to
                              a tender offer or exchange offer to
                              acquire voting Shares (or securities
                              convertible into shares) for cash,
                              securities or any other consideration,
                              provided that after consummation of the
                              offer, the person, group, partnership,
                              association, corporation or other
                              entity in question is the beneficial
                              owner (as defined in Rule 13(d)-3 under
                              the Act) directly or indirectly, of
                              20% or more of the then outstanding
                              voting Common Shares of the System
                              (calculated as directed in paragraph (d)
                              of Rule 13(d)-3 under the Act in the
                              case of rights to acquire Common Shares);

                        (3)   The Trustees of the System approve (a)
                              any consolidation or merger of the System
                              in which the System is not the continuing
                              or surviving entity or pursuant to
                              which Common Shares of the System would
                              be converted into cash, securities or
                              other property; or (b) any transaction
                              or series of related transactions the
                              result of which all or substantially all
                              the assets of the System are sold;

                        (4)   The System ceases to be a reporting
                              company pursuant to Section 13(a) of the
                              Securities Exchange Act of 1934 or any
                              similar successor provision; or

                        (5)   During any period of two consecutive
                              years (24-month period), individuals
                              who at the beginning of such period
                              constituted the Board of Trustees of the
                              System cease for any reason (other than
                              retirements or resignations in the
                              normal course of business) to constitute
                              a majority thereof; provided, however,
                              that any Trustee who is not in office
                                    PAGE 28


                              at the beginning of such 24-month period,
                              but whose election by the Board of Trustees
                              or whose nomination for election by the
                              System's Common Shareholders was to fill
                              a vacancy caused by death or retirement
                              and was approved by a vote of at least
                              two-thirds of the Trustees then still in        
                              office and who either were Trustees at the
                              beginning of such period or whose election
                              or nomination for election was previously
                              so approved, shall be deemed to have 
                              been in office at the beginning of such
                              period for purposes of this definition.

            (iii) If a Participant's employment by the System or one
                  of its subsidiaries terminates during the three-
                  year employment period described in paragraph 9(g)(i)
                  by reason of his or her retirement, as determined
                  by the Committee, the Committee may, in its
                  discretion, specify that the interest of the
                  Participant in any Grant Shares then subject to
                  forfeiture shall become vested at that time, at
                  a future date, or upon the completion of such 
                  other conditions as the Committee may provide.

10.   Rights as Shareholder.  Except as otherwise provided in
      paragraphs 9 and 13, a Participant shall have all of the rights
      of a shareholder of the System with respect to the Grant Shares
      registered in his or her name, including the right to vote such
      Grant Shares and receive dividends and other distributions
      paid or made with respect to such Grant Shares.  A Participant
      shall have the right to purchase Shares from such dividends
      and/or to reinvest dividends through the System's Dividend
      Reinvestment and Common Share Purchase Plan, and any such
      Shares purchased shall be immediately vested and not subject
      to forfeiture.

11.   Share Dividends; Share Splits; Share Combinations; Recapitalization.
      The Board of Trustees of the System may make appropriate
      adjustments in the maximum number of Shares subject to the Plan
      to give effect to any share dividends, Share splits, Share
      combinations, recapitalizations and other similar changes in
      the capital structure of the System.  The provisions contained
      in the Plan shall apply to any other capital shares of the
      System, and any other securities which may be acquired by
      the Participant as a result of a Share dividend, Share split,
      Share combination, or exchange for other securities resulting
      from any recapitalization, reorganization or any other
      transaction affecting the Grant Shares.

12.   No Employment Commitment; Tax Treatment.  Nothing herein
      contained shall be deemed to be or constitute an agreement
      or commitment by the System to continue the Participant
      in its employ.  The System makes no representation about
      the tax treatment to the Participant with respect to
      receiving, holding or disposing of the Grant Shares,
      including the possible application of Section 83 of the Code.
                                    PAGE 29


13.   Legends.  Unless and until Grant Shares are fully vested,
      certificates evidencing ownership of Grant Shares shall
      be kept under the possession and control of the System
      and shall contain appropriate statements setting forth
      the conditions and restrictions applicable to such
      Grant Shares as are set forth herein.  At the time
      restrictions have lapsed, the System will, upon satisfaction
      by the Participant of all withholding and other tax
      obligations, issue a new certificate without restrictions.

14.   Termination or Amendment of Plan.
      (a)   Except as provided in paragraph 14(b), the Board of
            Trustees may at any time suspend, reinstate, or 
            terminate the Plan or make such changes in or additions
            to the Plan as it deems advisable without further
            action on the part of the shareholders of the System,
            provided:

            (i)   that no such termination or amendment shall
                  adversely affect or impair any then issued and
                  outstanding Grant Shares without the consent
                  of the Participant holding such Grant Shares; and

            (ii)  that no such amendment which (a) materially
                  increases the maximum number of Grant Shares
                  subject to this Plan; (b) materially increases
                  the benefits accruing to Participants under
                  the Plan; or (c) materially modifies the
                  requirement as to eligibility for participation
                  in the Plan may be made without first obtaining
                  shareholder approval if independent legal 
                  counsel advises that such approval is necessary.

      (b)   In the event of a change in control (as defined in
            Section 9 (g)(ii)), the System may neither terminate
            the Plan nor reduce benefits under the Plan with
            respect to those individuals who are Participants as
            of the date of the change in control.

15.   Indemnification of Committee.  In addition to such other rights of
      indemnification as they may have as Trustees or as members of the
      Committee, each member of the Committee shall be indemnified by 
      the System against the reasonable expenses, including attorneys' 
      fees, actually and necessarily incurred in connection with the 
      defense of any action, suit or proceeding, or in connection with 
      any appeal therein, to which he/she may be a party by reason of 
      any action taken or any failure to act under or in connection with
      the Plan, or any Incentive Award granted thereunder, and against 
      all amounts paid by him/her in settlement thereof, provided such
      settlement is approved by independent legal counsel selected
      by the System, or paid by him/her in satisfaction of a judgment
      in any such action, suit or proceeding that such Committee
      member is liable for misconduct in his or her duties;
                                    PAGE 30


      provided that within 60 days after the institution of such
      action, suit or proceeding, the Committee member shall in
      writing offer the System the opportunity, at its own expense,
      to handle and defend the same.

16.   Governing Law.  This Plan shall be subject to and construed
      in accordance with the laws of the Commonwealth of Massachusetts.

               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Results of Operations

      Earnings

      Earnings and earnings per common share by organizational element for the
three-year period are summarized in the table below:

                                1993              1992              1991

                            44,604   4.37     38,606   3.83     32,925   3.31
      Freetown write-down      -       -         -       -     (14,805) (1.49)
        Total              $44,604  $4.37    $38,606  $3.83    $18,120  $1.82

      Parent company earnings and dividends on preferred shares were allocated
      among the electric, gas and other operations of the system based on the
      Parent's equity investment in each segment.

      1993 versus 1992

      In 1993, earnings improved by 15.5% due, in part, to a significant
reduction in other operation expense ($12.6 million or 6.1%) that reflects the
system's continued cost containment efforts.  These efforts included the
shutdown of the Cannon Street generating station in late 1992 which had a $1.5
million impact on other operation expense and a second quarter work force
reduction that provided a net payroll savings of $1.6 million.  A $2.7 million
decline in the provision for bad debt expense that resulted from improved
collection experience also contributed to the reduction in other operation. 
Other factors contributing to the improved earnings were: 1) higher retail
electric unit sales as well as an increase in firm gas sales during the
heating season; 2) new base rates for Cambridge Electric Light Company,
effective June 1, 1993 ($7.2 million on an annual basis); 3) the recognition
of "lost base revenues" ($2.4 million) relating to electric conservation and
load management (C&LM) programs; and 4) the reversal of a reserve ($3.8
million) following the resolution of uncertainties related to the system's
Seabrook investment which was included in retail base rates by the
Massachusetts Department of Public Utilities (DPU) in Cambridge Electric's
June 1993 rate order.

      1992 versus 1991

      Contributing to the overall increase in 1992 operating results were:  
1) significantly improved gas operations due to a 9.4% increase in firm unit
sales and a full year of higher base rates ($22.8 million) authorized in
November 1991; 2) the absence in 1992 of the Freetown Energy Park write-down
in late 1991; 3) lower short-term interest rates ($2.7 million); 4) a return
to more seasonable winter temperatures during the heating season; and 5) cost
control measures designed to eliminate or delay expenditures.  Earnings from
electric operations declined due, in part, to: 1) the need for higher base
rates for Cambridge Electric; 2) the undercollection of $3 million, due to the
existing cost recovery mechanism, of certain long-term purchased power
capacity costs; and 3) a decreased return on equity due to declining net plant
investment bases.

      Electric Revenues and Unit Sales

      Electric operating revenues for the years 1993, 1992 and 1991 consisted
of:

                                           1993         1992         1991

      Unit sales (in Megawatthours or MWH) for the years 1993, 1992 and 1991
consisted of:

                            1993                1992                 1991

      Customers served      352,000   1.1      348,000     -        348,000

      In 1993, electric operating revenues increased $26.8 million (4.5%) due
primarily to the net increase in fuel and purchased power costs of $35.8
million (11.4%), the base rate increase for Cambridge Electric ($7.2 million
on an annualized basis), a 1.9% increase in retail unit sales and the recovery
of approximately $2.4 million in lost base revenues related to electric C&LM
programs.  Partially offsetting these increases was a lower level ($9 million)
of C&LM program costs.  The decline in wholesale revenues of $2.8 million or
2.5% was due to a 5.9% drop in unit sales to non-associate utilities. 
Fluctuations in the level of wholesale electric sales have little, if any,
impact on earnings.

      For 1993, retail electric unit sales increased 1.9%, as each customer
segment continued to show improvement, offset somewhat by the impact of
conservation programs.  In particular, unit sales reflect a moderate increase
in customers, primarily residential, a greater demand for power from
commercial and seasonal customers, reflecting an improving economy and to a
lesser extent, more extreme weather conditions resulting in additional use to
meet heating or air conditioning requirements.

      1992 operating revenues decreased $10.1 million, or 1.7%, despite a net
increase in fuel and purchased power costs of $30.3 million or 10.7%, a 1.4%
increase in retail unit sales and a full year of higher base rates for
Commonwealth Electric Company.  This reduction was due primarily to a $26.3
million or 62% decrease in C&LM costs at Commonwealth Electric and Cambridge
Electric and a $6.9 million revenue decline associated with the operation of
Seabrook 1.  Wholesale revenues in 1992 declined 3.6% due to a 3.2% drop in
unit sales to non-associate utilities and the New England Power Pool.

      Revenues during a portion of 1991 and through 1993 also reflect the
impact of Commonwealth Electric's Economic Development Rate which became
effective on October 1, 1991.  Revenues were lower by $1.5 million, $1.3
million and $552,000 in 1993, 1992 and 1991, respectively.  These amounts
represent the difference between what certain commercial and industrial
customers would have paid prior to the availability of this rate.  For
additional information on this special rate, refer to the "Rates and
Regulatory Matters" section of this discussion.
                                    PAGE 35


      Retail electric unit sales increased by 1.4% in 1992 primarily due to
increases in the residential sector caused by a return to more normal (colder)
temperatures in the first and fourth quarters of the year, offset somewhat by
a cooler than average summer, C&LM programs and the prolonged negative impact
of the state's depressed economic condition.

      Fuel and Purchased Power

      The cost of fuel used for electric generation and purchased power per
KWH sold was $.042, $.037 and $.034 for 1993, 1992 and 1991, respectively. 
These costs constitute 56%, 52% and 47% of electric operating revenues for the
respective years.  The upward trend since 1991 reflects the impact of the
system's contractual obligations to take higher-cost power contracted for in
the 1980s when the system's customer base grew dramatically and forecasts
predicted continued growth.  These contracts, which are typically long-term,
will continue to drive costs up as additional capacity comes on line.  The
system is currently involved in negotiations to restructure or buy out certain
of these long-term contracts.

      For 1993 and 1992, fuel and purchased power costs increased $35.8
million or 11.4% and $30.3 million or 10.7%, respectively, due to higher unit
sales in both years and the contractual obligations discussed above including
additional power purchases from certain gas-fired independent power producing
(IPP) facilities.  Both 1993 and 1992 reflect reduced generation from Canal
Electric Company's units (for sales to non-associate utilities) and other oil-
fired units.  The increased costs for power from the IPPs and other sources
were offset somewhat by lower Seabrook 1 costs in both years.

      Reflected in the 1993 and 1992 cost is the increased use of a cleaner
burning but more expensive (1% sulphur) fuel oil at Canal Electric.  In
addition, fuel and purchased power expense for 1993, 1992 and 1991 includes
$5.6 million, $3.9 million and $872,000, respectively, of capacity-related
costs associated with certain purchased power contracts that were not
recovered in revenues due to the mechanism established by the DPU.  The impact
of this underrecovery reduced net income by $3.4 million, $2.5 million and
$538,000 in 1993, 1992 and 1991, respectively.  (Refer to the "Rates and
Regulatory Matters" section of this discussion for more information.)

      The system's energy mix, including purchased power, was as follows:

                                     1993         1992        1991

      Oil                             31%          41%         42%
      Nuclear                         26           27          31
      Natural gas                     29           21          15
      Waste-to-energy                  8            7           7
      Hydro                            3            2           3
      Coal                             3            2           2
        Total                        100%         100%        100%

      The system's energy mix has shifted during the last several years from
oil to natural gas and other types of generation due to the availability of
capacity from IPP facilities and, to a lesser extent, an effort to reduce its
reliance on oil.  In 1993, Commonwealth Electric began receiving power from:
1) an 11.1% entitlement in a 240 megawatt (MW) gas-fired cogeneration
facility, 2) a 17.2% entitlement in a 160 MW gas-fired cogeneration facility,
3) additional energy from the expansion of a waste-to-energy plant and 4) an
extended commitment to exchange 50 MW (25 MW in 1992) of Canal's oil-fired
generation with 50 MW of pumped storage capacity from non-affiliate New
England Power Company's Bear Swamp Units.  In 1991, Canal arranged for a long-
term exchange of power with Central Vermont Public Service Company (CVPS)
whereby 50 MW from Canal's oil-fired Unit 2 was exchanged for 25 MW from
CVPS's Vermont Yankee nuclear unit and 25 MW from its Merrimack Unit 2 coal-
fired facility.  This agreement expires in October 1995.  In certain
circumstances, it is possible to exchange capacity with another utility so
that the mix of power improves the pricing for dispatch for both the seller
                                    PAGE 36


and the purchaser.  The Canal/Bear Swamp transaction alone will save the
system's customers $2.7 million over a four-year period that began in June
1993.  These exchanges and other future capacity purchased power contracts
with natural gas-fired IPPs will continue to shift the system's energy mix
from oil to other energy sources.  In addition to power purchases, the system
is actively pursuing sales of certain available capacity to utilities in and
outside the New England region.

      Oil-fired generation, although reduced from prior years' levels, still
accounts for a major percentage of the system's total sources, including
purchased power.  Average oil prices in 1993 at Canal's generating plant, a
major supplier of electricity for the system, were $14.02 per barrel as
compared to $12.95 and $12.53 per barrel in 1992 and 1991, respectively.  In
conformance with tighter restrictions on stack emissions, the Commonwealth of
Massachusetts mandated a reduction in sulphur dioxide emissions requiring the
periodic use of lower-sulphur (1%) content oil.  In 1993, 1% oil averaged
$15.16 per barrel, a 12.1% decrease from the $17.25 cost in 1992.  However,
lower-sulphur oil displaced 57.5% of the higher-sulphur (2.2%) content oil as
compared to 24% in 1992.  This higher cost oil is reflected in the total
average cost per barrel for 1993 and 1992 but was not used at Canal in 1991. 
The price of oil is expected to average approximately $15.62 per barrel in
1994.

      Gas Revenues, Unit Sales and Cost of Gas

      Gas operating revenues for the years 1993, 1992 and 1991 consisted of:

      Unit sales (in billions of British thermal units or BBTU) for the years
1993, 1992 and 1991 consisted of:

      For 1993, gas operating revenues rose $7.8 million (2.6%) due primarily
to increases in C&LM costs ($4.8 million) which are being recovered through a
Conservation Charge (CC) decimal effective in late 1992 and the cost of gas
sold ($2.4 million).  Also contributing to the increase in revenues were
transition costs ($1.4 million) associated with the implementation of the
Federal Energy Regulatory Commission's (FERC) Order No. 636 (refer to the
"Cost Recovery" section of this discussion) and an increase in firm
transportation revenues ($474,000).  Offsetting these increases somewhat were
lower unit sales.

      Operating revenues for 1992 increased $42.6 million or 16.9% due to a
$15.1 increase in the cost of gas sold, new base rates approved for
Commonwealth Gas effective November 1, 1991, a 9.4% increase in firm unit
sales and a nearly $600,000 increase in firm transportation revenues.
                                    PAGE 37


      Firm gas sales declined by 1.5% in 1993, including a 10.9% decline in
sales to industrial customers; however, firm sales during the heating season
when seasonal rates are in effect increased by nearly 3%.  Although
interruptible sales decreased 23% during 1993, these sales have little, if
any, impact on net income.  In 1992, firm unit sales increased 9.4% due to
significantly higher residential and commercial customer use caused by colder
temperatures in the first and fourth quarters.  The variations from year to
year in weather conditions, particularly during the heating seasons, cause gas
usage to fluctuate.  1992 weather patterns were more normal than 1991.

      Customers increased at a rate of 2.2% in 1993 due to new home construc-
tion and conversion activity.  The fluctuation in interruptible sales during
the three-year period reflects the competitive market conditions for energy
resources.  However, interruptible sales have little impact on earnings.

      The cost of gas sold per MMBTU averaged $3.81, $3.65 and $3.54 in the
years 1993, 1992 and 1991, respectively.  In 1994, the cost of gas is expected
to cost approximately $4.40 per MMBTU due to the impact of FERC Order No. 636
and rising transportation costs.

      Other Operation and Maintenance

      In 1993, other operation decreased $12.6 million or 6.1% due to the
absence in the current year of costs associated with Commonwealth Electric's
Cannon Street generating station ($1.5 million) which ceased operations in
October 1992 and the net savings of $1.6 million ($5.3 million in payroll
savings less $3.7 million in severance costs) associated with the second
quarter work force reduction.  Also contributing to the decrease in costs in
1993 was the provision for bad debts expense which declined $2.7 million or
22.8% due to improved payment experience, lower liability insurance costs of
$1.7 million due to lower claims, lower Seabrook operating costs of $1.7
million and a decline in employee medical and life insurance costs of
$800,000.  Offsetting these decreases somewhat was an increase in pension
costs of $1.2 million.

      In 1992, other operation increased 6.1% due to higher costs for medical
and other types of insurance and consulting fees incurred primarily as a
result of an independent management audit which was conducted for Commonwealth
Electric during the year by order of the DPU.  Also, the provision for bad
debts increased by $900,000 reflecting the difficult economic conditions in
the system's service territory and a decline in fuel assistance programs. 
Offsetting these increases in 1992 was a $2.2 million reduction in net pension
expense as a result of asset valuation changes and Commonwealth Electric's
deferral of $1.4 million of accrued pension costs pursuant to rate-making
treatment.  Additionally in 1992, there were positive results from the
system's cost containment efforts, including reduced overtime, work force
reductions through attrition, early retirements and the elimination of forty
positions and associated costs with the closing of Commonwealth Electric's
Cannon Street generating station in the fourth quarter.

      The total number of full-time employees declined 11.7% to 2,217 in 1993
from 2,510 employees at year-end 1991.  Management views the current work
force level to be adequate for service to its customers.

      On October 1, 1992, Commonwealth Electric ceased power generation at its
59 MW Cannon Street station located in New Bedford, Massachusetts.  Fuel costs
for this facility were $544,000 and $2.1 million in 1992 and 1991, respective-
ly, and operations and maintenance costs were $2.2 million and $2.4 million in
1992 and 1991, respectively.  After reviewing several alternatives for the
facility including re-powering, management decided to abandon the plant in
1993.  The sharp decline in electric demand brought about by an economic
slowdown was a key factor in the decision to close the plant.  Additionally,
forecasts for electric demand indicated an excess regional supply in the near
term and no need for increased generating capacity until the late-1990s or
beyond.  In 1993, a regulatory asset was established for the net book value of
the plant of approximately $4 million in anticipation of recovery.
                                    PAGE 38


      Maintenance in 1993 increased by $700,000 or 1.9% due primarily to a
scheduled major inspection and overhaul of the Canal 2 boiler, turbine and
generator.  In 1992, maintenance decreased $4.5 million or 10.1% due to
reduced transmission and distribution related costs and the absence of major
repairs to Canal Unit 1 that were experienced in 1991.

      Depreciation, Amortization and Taxes

      Despite the higher level of depreciable plant, depreciation expense
declined by approximately $700,000 or 1.6% during 1993 due to an adjustment
made to the accrual rate used by Canal Electric to reflect an extension of the
depreciable life of Unit 1 from 1996 to 2002.  This change reduced
depreciation expense for the year 1993 by approximately $3.5 million but had
no impact on net income because the new estimate is reflected in bills to
customers.  The abandonment of the Cannon Street generating station also
contributed to the decrease in 1993.  In 1992, depreciation increased by 2.9%
due to a higher level of depreciable plant-in-service.

      The decline in amortization for 1993 of $1.7 million or 21.9% was due to
the absence in the current period of amortization costs related to
Commonwealth Gas' automated mapping system.  In 1992, the $5 million rise in
amortization costs was due to a change made in 1991 in the recovery period of
Seabrook 1 non-construction costs from one year to ten years pursuant to a
settlement with the FERC.  Amortization of these costs began with commercial
operation of the unit in 1990.

      Income tax expense increased $7.7 million or 37.5% in 1993 due to the
significantly higher level of pretax income, and to a lesser extent, an
increase in the federal income tax rate to 35%, retroactive to January 1,
1993.  In 1992, income tax expense increased $1.6 million or 8.7% as a result
of higher pretax income from the system's primary businesses.

      The 2.7% change in local property taxes in 1993 primarily reflects
higher property tax rates.  Local property taxes increased in 1992 by $3.9
million or 32% reflecting higher tax rates and/or assessments in the majority
of the communities the system serves and also reflected a $435,000 increase in
the nuclear station property tax assessed by the State of New Hampshire on the
joint owners of Seabrook.  The 3.8% increase in payroll and other taxes for
1993 was due to an increase in unemployment tax rates.

      Conservation and Load Management (C&LM)

      Cambridge Electric, Commonwealth Electric and Commonwealth Gas have
received approval from the DPU to recover in revenues costs associated with
C&LM programs through the operation of a Conservation Charge (CC) decimal on a
dollar-for-dollar-basis.  For the years ended December 31, 1993, 1992 and
1991, C&LM costs (including amortization of prior period amounts) were as
follows:

                                     1993        1992          1991
                                         (Dollars in Thousands)

      Cambridge Electric            $ 2,905     $ 4,246       $ 8,135
      Commonwealth Electric           4,165      11,826        34,199
      Commonwealth Gas                5,094         286           -  
                                    $12,164     $16,358       $42,334

      Other Income

      The substantial increase in other income during 1993 reflects the
reversal of a reserve ($3.8 million pretax) related to the system's Seabrook 1
investment.  The decision to eliminate the reserve was prompted by the
allowance of Seabrook 1 costs in base rates at the state level for Cambridge
Electric.  Offsetting this, in part, was the absence in the current year of an
equity component of allowance for funds used during construction (AFUDC).  The
$1.8 million in equity AFUDC for 1992 resulted from an adjustment to reflect a
                                    PAGE 39


final FERC settlement which provided for the full recovery of the system's
Seabrook investment.

      Other income increased by 110% in 1992 due to the absence of the $14.8
million after-tax write-down which resulted from cancellation of the Freetown
Energy Park project and the $1.8 million equity component of AFUDC which
relates to the aforementioned FERC settlement.  Also included in 1992 was
Commonwealth Electric's Hurricane Bob (August 1991) expenses of $9.2 million
($5.7 million after-tax) which had been deferred in 1991 pending regulatory
action.  The impact of this write-off was neutralized by receipt of DPU and
Internal Revenue Service authorization to retain certain tax reserves which
would normally be returned to customers.

      Interest Charges

      For 1993, interest charges increased $2.5 million or 6.1% due to a
lower level of AFUDC debt resulting from the Seabrook settlement noted
previously and an increase in interest on long-term debt of $700,000 primarily
due to the issuance of $65 million in new long-term notes in the first quarter
of 1993.  Somewhat offsetting these increases was a $300,000 decline in other
interest charges that was due to lower interest rates and a lower average
level of short-term borrowings ($103 million versus $126 million).  Interest
rates on short-term bank borrowings averaged 3.5% in 1993 as compared to 4%
for 1992.  Total interest charges decreased 11% in 1992 due primarily to a
$1.5 million increase in the debt component of AFUDC relating to the Seabrook
investment and a $2.7 million or 27.5% reduction in short-term interest
charges.  Despite a higher average level of bank borrowings created, in part,
by the retirement of several long-term debt issues during 1992, short-term
interest declined due to lower interest rates on bank borrowings (4% versus
6.3% for 1991).

      New Accounting Standards

      Effective January 1, 1993, the system adopted the provisions of
Statement of Financial Accounting Standards No. 106, "Employers' Accounting
for Postretirement Benefits Other Than Pensions."  This statement establishes
new accounting and reporting standards for postretirement benefits other than
pensions.  For further information, refer to Note 4(b) of the Notes to
Consolidated Financial Statements.

      In 1992, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 112, "Employers' Accounting for
Postemployment Benefits" (SFAS 112).  The system is required to adopt this
statement effective January 1, 1994.  SFAS 112 requires employers to recognize
the obligation to provide benefits to former or inactive employees after
employment but before retirement (postemployment).  Those benefits include
salary continuation, supplemental employment benefits, severance benefits,
disability-related benefits and continuation of benefits such as health care
and life insurance coverage if each of the following conditions are met: 1)
the obligation is attributable to employee services already rendered, 2)
employees' rights to those benefits accumulate or vest, 3) payment of the
benefits is probable and 4) the cost of the benefits can be reasonably
estimated.  The system believes that the adoption of the provisions of SFAS
112 will not have a material impact on its financial position or results of
operations.

Rates and Regulatory Matters

      Certain System utility subsidiaries operate under the jurisdiction of
the DPU, which regulates retail rates, accounting, issuance of securities and
other matters.  The DPU requires historic test-year information to support
changes in rates.  In addition, Canal Electric, Cambridge Electric and
Commonwealth Electric file their respective wholesale rates with the FERC.
                                    PAGE 40


      Retail Rate Proceedings

      The most recent general rate proceedings approved by, or settled with,
the DPU for the System's retail electric and gas subsidiaries are as follows:

                                                             Return on

* Returns are for accounting purposes only.

      On May 28, 1993, the DPU issued an order, based on a June 30, 1992 test
year, increasing Cambridge Electric's retail revenues by approximately $7.2
million, or 6.4%.  More than 80% of the increase related to: 1) plant
additions since Cambridge Electric's last retail rate proceeding in 1989; 2)
capacity costs associated with certain long-term purchased power contracts;
and 3) costs of postretirement benefits other than pensions.  The costs
associated with postretirement benefits other than pensions were determined in
accordance with SFAS No. 106.  The DPU authorized recovery of these costs over
a four-year period with carrying costs on the deferred portion.  The new base
rates also reflect costs associated with power from the Seabrook nuclear power
plant which are billed to Cambridge Electric by Canal Electric.  Previously
these costs were recovered through Cambridge Electric's Fuel Charge decimal.

      The Commonwealth Gas settlement provided an 11.3% increase in revenues
(9% of 1990 revenues) and was the company's first rate increase request since
May 1987.  The increase was necessitated by the rising costs of providing
service to customers and substantial expenditures to upgrade, improve and
maintain the Commonwealth Gas distribution system.

      The Commonwealth Electric rate order provided a 3.1% increase in
revenues over the test year ended June 30, 1990.  The DPU also ordered the
Company to undertake an independent management audit in 1992.  In October
1992, the DPU released the results of the audit which evaluated existing
activities and processes and identified opportunities for improved operations
in the areas of strategic planning, budget development, control of capital and
operational costs, management of outside services, employment policies and
customer services.  Throughout 1993, follow-up discussions were held between
Commonwealth Electric and the DPU regarding the status of each audit
recommendation with both parties expressing overall satisfaction with their
progress.  Changes in the implementation plan were discussed, with the plan
expected to be complete in 1994.

      Economic Development Rate

      In an effort to foster industrial development in its service area,
Commonwealth Electric began offering an Economic Development Rate (EDR) on
October 1, 1991.  The rate is offered to new or existing industrial customers
who have an electric demand of 500 kilowatts or more and meet specific
financial and other criteria.  As of December 31, 1993, twenty-two industrial
customers are benefitting from this special rate.  The rate is available for a
six-year term.  In 1993, the DPU conducted a generic investigation into EDRs
and rendered a decision on September 1, 1993 that established rate design
guidelines and minimum customer eligibility requirements.  Commonwealth
Electric refiled its EDRs to comply with the ruling.  The new EDR is available
to both commercial and industrial customers with loads greater than 500
kilowatts.  Commonwealth Electric also received approval for a Vacant Space
Rate which it filed in conformance with the new EDR guidelines that is
available to qualifying small commercial and industrial customers who
establish loads in previously unoccupied building space.

      Cost Recovery

         Fuel and Purchased Power and Purchased Gas

      Commonwealth Electric and Cambridge Electric file Fuel Charge rate
schedules, subject to DPU regulation, under which they are allowed current
recovery, from retail customers, of fuel used in electric generation and a
substantial portion of purchased power, demand and transmission costs.

      Cambridge Electric and Commonwealth Electric collect a portion of their
capacity-related purchased power costs associated with certain long-term power
arrangements through base rates.  The recovery mechanism for these costs uses
a per kilowatthour (KWH) factor that is calculated using historical (test-
period) capacity costs and unit sales.  This factor is then applied to current
monthly KWH sales.  When current period capacity costs and/or unit sales vary
from test-period levels, Cambridge Electric and Commonwealth Electric
experience a revenue excess or shortfall which can have a significant impact
on net income.  All other capacity and energy-related purchased power costs
are recovered through the Fuel Charge.  Cambridge Electric and Commonwealth
Electric made a filing in late 1992 with the DPU seeking an alternative method
of recovery.  This request was denied in a letter order issued on October 6,
1993.  However, Cambridge Electric and Commonwealth Electric were encouraged
by the DPU's acknowledgement that the issues presented warrant further
consideration.  The DPU encouraged each company to continue to work with other
interested parties, including the Attorney General of Massachusetts, to reach
a consensus solution on the issue for consideration in each company's next
base rate proceeding.

      Commonwealth Gas has a standard seasonal Cost of Gas Adjustment rate
schedule which provides for the recovery, from firm customers, of purchased
gas costs not recovered through base rates.  These adjustment charges, which
require DPU approval, are estimated semi-annually and include credits for gas
pipeline refunds and profit margins applicable to interruptible sales.  Actual
gas costs are reconciled annually as of October 31, and any difference is
included as an adjustment in the calculation of the decimals for the two
subsequent six-month periods.

      On April 8, 1992, the FERC issued Order No. 636 (Order 636), requiring
interstate pipelines to unbundle (separate) existing gas sales contracts into
separate components (gas sales, transportation and storage services).  Order
636 provides mechanisms which will allow customers to reduce the level of firm
services from pipelines and permits the "brokering" of excess capacity on a
temporary or permanent basis.  Order 636 also requires pipelines to provide
transportation services which allow customers to receive the quality of
service they had with bundled contracts.  Refer to Note 2(g) of the Notes to
Consolidated Financial Statements for more information.

         C&LM Programs

      The system has implemented cost-effective C&LM programs for its gas and
electric ratepayers which are designed to reduce future energy use.  On June
30, 1993, the DPU issued an order in Phase I of a C&LM cost recovery filing
made by Cambridge Electric and Commonwealth Electric which allows the recovery
of "lost base revenues" from electric customers.  The recovery of lost base
revenues is allowed by the DPU to encourage effective implementation of C&LM
programs.  The KWH savings that are realized as a result of the successful
implementation of C&LM programs serve as the basis for determining lost base
revenues.  The amount to be recovered is approximately $3.6 million for
Commonwealth Electric and Cambridge Electric combined and is based on
anticipated KWH savings for the eighteen-month period beginning January 1,
1993.  The revenue will be recovered from customers over a twelve-month period
which began July 1, 1993.  Through December 31, 1993, the combined recovery
was approximately $2.4 million.

      On October 25, 1993, the DPU issued an order in Phase II of the C&LM
proceeding.  In that order, the DPU disallowed approximately $195,000 in
expenditures that it determined exceeded benefits to customers.  In addition,
                                    PAGE 42

the DPU ruled that approximately $1.6 million in C&LM Task Force related
expenditures are not recoverable by Commonwealth Electric and Cambridge
Electric "at this time" because certain programs have yet to be implemented
and thus ratepayers are receiving no current benefits.  The Companies have
removed these costs from the current CC decimal.  Commonwealth Electric and
Cambridge Electric are continuing with the development of the programs and
plan to seek recovery of these costs in a subsequent filing with the DPU. 
Based on the language in the order and subsequent discussions with the parties
involved in the proceeding, management believes that the ultimate recovery of
a substantial portion of these costs is likely.

      Commonwealth Gas offers conservation measures to its residential,
commercial and industrial customers through formal programs approved by the
DPU in June 1992.  On November 1, 1992, Commonwealth Gas implemented
separately stated CC decimals pursuant to its cost-recovery mechanism.

Environmental Matters

      Commonwealth Gas is a potentially responsible party (PRP) in the
Sullivan's Ledge Superfund site in New Bedford, Massachusetts.  In 1990,
Commonwealth Gas agreed to a settlement regarding this site and its share of
clean-up costs is presently estimated to be $1.8 million and is reflected on
the Consolidated Balance Sheets.  Sampling work at the site indicates that a
more extensive clean-up than originally contemplated may be required, although
the financial impact of these findings is not presently known.  The settling
parties for the site are now pursuing claims against a number of non-settling
PRPs, and any amounts recovered through those claims will be applied to offset
the settling parties' liabilities.

      Commonwealth Gas is evaluating a former gas manufacturing plant site in
Worcester, Massachusetts, and a proposal for a comprehensive assessment of
this site has been prepared, and it is possible that this site may require
substantial remediation work due to the suspected presence of hazardous
substances.  However, the cost of remediation cannot be estimated at this
time.

      Commonwealth Gas anticipates recovery of costs associated with the
clean-up of such sites from its customers through a procedure established in a
generic order issued by the DPU, wherein such costs are recovered through an
element of the existing Cost of Gas Adjustment Clause (CGA).

      COM/Energy Research Park Realty (RPR), another system subsidiary, owns a
parcel of land on Third Street in Cambridge, Massachusetts, which was also
formerly the site of a gas manufacturing facility.  While the Massachusetts
Department of Environmental Protection has not designated this site as being
contaminated by hazardous substances, it is expected that RPR, in conjunction
with any future development of this site, will conduct a site assessment to
determine if clean-up activities are necessary.  RPR, a non-regulated entity,
would be responsible for the costs associated with any such activities.

      In October 1993, the system reached an agreement with Montaup Electric
Company (the 50% owner of Canal Unit 2) and Algonquin Gas Transmission Company
to build a natural gas pipeline that will serve the Canal Unit 2 generating
station, subject to regulatory approvals.  Unit 2 will be modified to burn gas
in addition to oil.  The project will improve air quality on Cape Cod, enable
the plant to exceed the stringent 1995 air quality standards established by
the Massachusetts Department of Environmental Protection and strengthen the
system's bargaining position as it seeks to secure the lowest-cost fuel for
its customers.  Plant conversion and pipeline construction are expected to be
completed in 1996.

Liquidity and Capital Resources

      Overview

      Capital resources of the System and its subsidiaries are derived
principally from retained earnings and equity funds provided through the
                                    PAGE 43

System's Dividend Reinvestment and Common Share Purchase Plan (DRP).  Supple-
mental interim funds are borrowed on a short-term basis and, when necessary,
replaced with new equity and/or debt issues through permanent financing
secured on an individual company basis.  The System and its subsidiaries have
over the years, maintained adequate financial resources and availability to
the capital markets and further, do not anticipate a change in 1994 or beyond. 
The System purchases 100% of all subsidiary common stock issues and provides,
to the extent possible, a portion of the subsidiaries' short-term financing
needs.  In 1993, the System purchased $53 million in subsidiary stock which
provides funds for subsidiary companies' construction programs, current
operations, debt service and other capital requirements.

      Capital Requirements

      Construction expenditures for 1993 were $54.6 million, including AFUDC. 
Sinking fund requirements and redemptions of long-term debt amounted to $44
million for a total capital requirement of $98.6 million, a decrease of $11.9
million from the 1992 level.  Of this amount, $51.1 million, or 52%, was
provided from internally generated funds.  The system anticipates that future
capital requirements, as shown below, will be met primarily through internally
generated funds, supplemented by a combination of debt and equity financings. 
The timing and amount of future debt and equity financings will be dictated by
economic and financial market conditions and the needs of system subsidiaries.

      Capital requirements estimated for 1994 through 1998 are as follows:

                                    1994   1995  1996  1997  1998  Total
                                           (Dollars in Millions)

      Sources of Capital

      On March 31, 1993, Commonwealth Electric Company issued long-term notes
totaling $65 million and 437,500 shares of Common Stock ($25 par value) for
$35 million.  The notes, which were sold through a private placement with
institutional investors, consisted of the following:

         10 Year, 7.43% Notes, Due 2003                  $15,000,000
         15 Year, 7.70% Notes, Due 2008                   10,000,000
         20 Year, 7.98% Notes, Due 2013                   25,000,000
         30 Year, 8.47% Notes, Due 2023                   15,000,000
                                                         $65,000,000

      The proceeds from the notes, together with the proceeds from
Commonwealth Electric's sale of common stock to the System, were used to repay
outstanding short-term debt incurred to temporarily finance additions to
property, plant and equipment, and the early retirement on March 1, 1993 of
three series of long-term debt, as follows:

         Series E, 8.125% Notes, Due 1995                $ 4,860,000
         Series B, 6.125% Notes, Due 1997                  4,440,000
         Series F, 8.375% Notes, Due 1998                 12,000,000
                                                         $21,300,000

      Commonwealth Electric paid a premium totaling $337,000 on the early
retirement of the debt and is amortizing this amount to expense over the
remaining original life of the retired issues.

      On December 1, 1993, Canal Electric redeemed its Series D, 11.125% Bonds
due December 1, 2007 totaling $9.3 million with short-term borrowings.  Canal
paid a premium of $279,000 on this early redemption and will amortize this
amount to expense over the remaining original life of the retired issue.
                                    PAGE 44


      In late December 1993, Commonwealth Gas issued $35 million in First
Mortgage Bonds, Series K, 7.11%, due December 30, 2033.  The proceeds from
this forty-year issue, together with an $18 million common stock issue
purchased by the Parent, were used to repay a portion of short-term debt that
had been incurred to temporarily finance construction expenditures and for
other working capital needs.  Additionally, Hopkinton LNG Corp. issued a $9
million Note with a variable rate, due in 1998.  The proceeds were used
primarily to refinance a $7 million Note, 7.11%, that matured during the
fourth quarter of 1993.  The balance was used to satisfy other working capital
requirements.

      It is anticipated that approximately $337 million or nearly 68% of the
projected capital requirements shown in the "Capital Requirements" section
above will be provided from internal sources, a portion of which is the
collection of accounts receivable generated from the sale of electricity, gas
and steam to retail and wholesale customers.  Other cash sources include
rental income, dividends from investments, the sale of Common Shares through
DRP and periodic short-term borrowings from banks.

      Capital financings during the five-year forecast period are projected to
be issued by subsidiary companies, including common stock issued exclusively
to the System as follows:

                                    1996    1997   1998   Total
                                      (Dollars in Millions)

        Long-term debt              $ 72    $ 38   $  9   $119
        Common stock                  32      29      -     61
           Total                    $104    $ 67   $  9   $180

      In addition, the System could raise further capital through the issuance
of additional series of preferred shares or additional Common Shares; however,
there are no projected financings of this type anticipated at this time.

      Cash provided by subsidiary company operations continues to be the
primary source of funds in addition to proceeds from DRP.  The proceeds from
these sources were used to provide for the payment of dividends and meet
capital requirements.  The System believes its capital resources and liquidity
are sufficient to meet its current and projected requirements.

      System companies also maintain lines of credit with banks.  At December
31, 1993, short-term notes payable to banks were $72 million, a decrease of
$93.6 million from last year's level of $165.6 million.  Bank borrowings are
used to temporarily fund construction projects and to repay the long-term debt
of the System and its subsidiary companies ($37.6 million in 1993). 
Arrangements for bank lines of credit totaled $115 million in committed lines
and $70 million in uncommitted lines at December 31, 1993, at which time $113
million was available to the system.  At December 31, 1998, the system's level
of bank borrowings is projected to be approximately $82 million.

      Subsidiary companies also participate in the COM/Energy Money Pool (the
Pool).  This is an arrangement whereby subsidiary companies' short-term cash
surpluses are used to help meet the short-term borrowing needs of the utility
subsidiaries.  In general, lenders to the Pool receive a higher rate of return
than they otherwise would on such investments, while borrowers pay a lower
interest rate than those available from banks.

      Capital Structure

      The system's objective is to maintain a capital structure that preserves
an appropriate balance between debt and equity.  All long-term debt, preferred
shares and common equity issued by the system is ultimately used to repay
                                    PAGE 45


short-term debt.  The system's capitalization structure, including maturing
long-term debt, is presented below:

                           1992              1993                 1998      
                                    (Dollars in Thousands)

operating controls, compliance with system policies and procedures and the
safeguarding of system assets.

      The responsibility of our independent auditors' examination is limited
to the expression of an opinion as to the fairness of the financial statements
presented.  The independent auditors are selected by the Board of Trustees and
report their findings thereto through the Audit Committee, which is comprised

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



      To the Board of Trustees of Commonwealth Energy System:

      We have audited the accompanying consolidated balance sheets and
consolidated statements of capitalization of COMMONWEALTH ENERGY SYSTEM (a
Massachusetts trust) and subsidiary companies as of December 31, 1993 and
1992, and the related consolidated statements of income, changes in common
shareholders' investment, changes in redeemable preferred shares and cash
flows for each of the three years in the period ended December 31, 1993. 
These financial statements are the responsibility of the System and subsidiary
companies' management.  Our responsibility is to express an opinion on these
financial statements based on our audits.

      We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

      In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of the System and
subsidiary companies as of December 31, 1993 and 1992, and the results of
their operations and their cash flows for each of the three years in the
period ended December 31, 1993, in conformity with generally accepted
accounting principles.

      As discussed in Note 4 to the consolidated financial statements,
effective January 1, 1993, the System and subsidiary companies changed their
method of accounting for costs associated with postretirement benefits other
than pensions.

                          COMMONWEALTH ENERGY SYSTEM

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1)   Significant Accounting Policies

      (a)  General and Regulatory

      Commonwealth Energy System, the parent company, is referred to in this
report as the "System" and, together with its subsidiaries, is collectively
referred to as "the system."  The operating companies are regulated as to
rates, accounting and other matters by various authorities including the
Federal Energy Regulatory Commission (FERC) and the Massachusetts Department
of Public Utilities (DPU).

      Regulated subsidiaries of the System have established various regulatory
assets in cases where the DPU and/or the FERC have permitted, or are expected
to permit, recovery of specific costs over time.  At December 31, 1993,
principal regulatory assets included in deferred charges were $21.9 million
for transition costs associated with FERC Order 636, $15.5 million for
unrecovered plant and decommissioning costs for the Yankee Atomic nuclear
plant, $15.5 million for abandonment and nonconstruction costs related to the
Seabrook project, $8.9 million for postretirement benefits costs, $7.4 million
in litigation costs associated with a settlement agreement with Boston Edison
Company relative to the Pilgrim nuclear plant and $7.3 million related to
deferred income taxes.  The more significant regulatory liabilities, reflected
in deferred credits, include $17.9 million related to income taxes and $15.5
million related to the Yankee Atomic nuclear plant.

      (b)  Principles of Consolidation

      The consolidated financial statements include the accounts of the System
and all of its subsidiary companies.  All significant intercompany accounts
and transactions have been eliminated in consolidation.

      (c)  Reclassifications

      Certain prior year amounts are reclassified from time to time to conform
with the presentation used in the current year's financial statements.

      (d)  Equity Method of Accounting

      The system uses the equity method of accounting for investments in
corporate joint ventures due, in part, to its ability to exercise significant
influence over operating and financial policies of these entities.  Under this
method, it records as income the proportionate share of the net earnings of
the joint ventures with a corresponding increase in the carrying value of the
investment.  The investment is reduced as cash dividends are received.  The
system conducts business with the corporate joint ventures in which it has
investments, principally four nuclear generating facilities located in New
England and a 3.8% interest in Hydro-Quebec Phase II.

      (e)  Operating Revenues 

      Customers are billed for their use of electricity and gas on a cycle
basis throughout the month.  To reflect revenues in the proper period, the
estimated amount of unbilled sales revenue is recorded each month.

      System utility companies are generally permitted to bill customers
currently for fuel used in electric production, purchased power and
transmission costs, total gas costs and conservation and load management costs
through adjustment clauses.  Amounts recoverable under these clauses are
subject to review and adjustment by the DPU.  Cambridge Electric Light Company
(Cambridge) and Commonwealth Electric Company (Commonwealth Electric) collect
a portion of capacity-related purchased power costs associated with certain
long-term power arrangements through base rates.  The amount of such fuel and
energy costs incurred but not yet reflected in customers' bills, which totaled
$5,565,000 in 1993 and $8,315,000 in 1992, is recorded as unbilled revenues.

                          COMMONWEALTH ENERGY SYSTEM

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

      (f)  Depreciation

      Depreciation is provided using the straight-line method at rates
intended to amortize the original cost and the estimated cost of removal less
salvage of properties over their estimated economic lives. The average
composite depreciation rates were as follows: 

                                     1993    1992    1991

      Electric                       3.28%   3.49%   3.49%
      Gas                            2.95    2.90    2.94
      Steam                          3.61    3.50    3.50
      LNG                            3.07    3.00    2.89

      (g)  Allowance for Funds Used During Construction

      Under applicable rate-making practices, system companies are permitted
to include an allowance for funds used during construction (AFUDC) as an
element of their depreciable property costs.  This allowance is based on the
amount of construction work in progress that is not included in the rate base
on which utility companies earn a return.  An amount equal to the AFUDC so
capitalized in the current period is reflected in the accompanying
Consolidated Statements of Income.

      While AFUDC does not provide funds currently, these amounts are
recoverable in revenues over the service life of the constructed property. 
The amount of AFUDC recorded was at a weighted average rate of 3.9% in 1993,
4.5% in 1992 and 6.7% in 1991.

(2) Commitments and Contingencies

      (a)  Construction

      The system is engaged in a continuous construction program presently
estimated at $358.3 million for the five-year period 1994 through 1998.  Of
that amount, $71.9 million is estimated for 1994.  The program is subject to
periodic review and revision.

      (b)  Seabrook Nuclear Power Plant

      The system's 3.52% interest in the Seabrook nuclear power plant is owned
by Canal Electric Company (Canal), a wholesale electric generating subsidiary,
to provide for a portion of the capacity and energy needs of affiliates
Cambridge and Commonwealth Electric.  Canal is recovering 100% of its Seabrook
1 investment through a power contract with Cambridge and Commonwealth Electric
pursuant to FERC and DPU approval.

      Pertinent information with respect to Canal's joint-ownership interest
in Seabrook 1 and information relating to operating expenses which are
included in the accompanying financial statements are as follows:

                              $17,167   $18,911   $19,058

      Canal and the other joint owners have established a Seabrook Nuclear
Decommissioning Financing Fund to cover post operational decommissioning
costs.  For the years 1993, 1992 and 1991, Canal paid $259,000, $235,000 and
$181,000, respectively, as its share of the cost of this fund.  The estimated
cost to decommission the plant is $366 million.  Canal's share, less its share
of the market value of the decommissioning trust, would amount to
approximately $11.6 million.

      (c) Price-Anderson Act

      The Price-Anderson Act (the Act) is a federal statute that includes
among its provisions a requirement that licensees of nuclear electric
generating units maintain financial protection to cover public liability
claims resulting from a nuclear incident or precautionary evacuation.  In
1988, Congress enacted a 15 year extension of the Act and increased the
available insurance and the maximum liability.  The higher liability is
provided by existing private insurance and retrospective assessments for costs
in excess of that covered by insurance, up to $66.15 million for each nuclear
reactor which is licensed to operate with a maximum assessment of $10 million
per incident within one calendar year.  Based on the system's equity ownership
interest in four nuclear generating facilities and its 3.52% joint-ownership
interest in Seabrook 1, the system's retrospective premium could be as high as
$1.9 million yearly or a cumulative total of $12.6 million, exclusive of the
effect of inflation indexing (at five-year intervals) and a 5% surcharge ($3.3
million) in the event that total public liability claims from a nuclear
incident exceed the funds available to pay such claims.

      (d)  Power Contracts and Support Agreements

      Cambridge and Commonwealth Electric have long-term contracts for the
purchase of electricity from various sources.  Generally, these contracts are
for fixed periods and require payment of a demand charge for the capacity
entitlement and an energy charge to cover the cost of fuel. Pertinent
information with respect to life-of-the-unit contracts for power from
operating nuclear units is as follows:

                           Connecticut    Maine       Vermont

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

      The system has also contracted to purchase power and transmission
capacity from various other generating and transmission facilities as follows:

                                                                Estimated

      Costs under these and other contracts are included in electricity
purchased for resale in the accompanying Consolidated Statements of Income and
are recoverable in revenues through either the Fuel Charge or in base rates.

      (e)  Yankee Atomic Nuclear Power Plant

      On February 26, 1992, the Board of Directors of Yankee Atomic Electric
Company agreed to permanently discontinue power operation of its plant and, in
time, decommission that facility.  This plant provided less than 1% of system
capacity.  Cambridge's and Commonwealth Electric's respective 2% and 2.5%
investment in Yankee Atomic is approximately $1 million.  Presently, purchased
power costs, which include a provision for ultimate decommissioning of the
unit, are billed to Cambridge and Commonwealth Electric and collected from
customers.

      Cambridge and Commonwealth Electric have estimated their unrecovered
share of all costs associated with the shutdown of the facility, recovery of
their respective plant investment and decommissioning and closing the plant to
be approximately $15.5 million.  This amount is reflected in the accompanying
Consolidated Balance Sheets as a liability and a corresponding regulatory
asset at December 31, 1993.

      (f) Environmental Matters

      The system is subject to laws and regulations administered by federal,
state and local authorities relating to the quality of the environment.  These
laws and regulations affect, among other things, the siting and operation of
electric generating and transmission facilities and can require the
installation of expensive air and water pollution control equipment.  These
regulations have had an impact upon the System's operations in the past and
will continue to have an impact upon future operations, capital costs and
construction schedules of major facilities.  For additional information, see
"Environmental Matters" in Management's Discussion and Analysis of Financial
Condition and Results of Operations.

      (g)  FERC Order No. 636

      On April 8, 1992, the FERC issued Order No. 636 (Order 636), requiring
interstate pipelines to unbundle (separate) existing gas sales contracts into
separate components (gas sales, transportation and storage services).  Order
636 provides mechanisms that will allow customers such as Commonwealth Gas to
reduce the level of firm services from pipelines and permits the "brokering"
of excess capacity on a temporary or permanent basis.  Order 636 also requires
pipelines to provide transportation services which allow customers to receive
the same level of service they had with bundled contracts.  Pipelines were
required to be operating under Order 636 by November 1, 1993.
                                    PAGE 58

                          COMMONWEALTH ENERGY SYSTEM

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

      As a result of implementing Order 636, each pipeline company is allowed
to collect certain "transition costs" from their customers. Commonwealth Gas
has been billed a total of approximately $16.9 million from  Tennessee Gas
Pipeline Company, Algonquin Gas Transmission Company and Texas Eastern
Transmission Company through December 31, 1993.  It is anticipated that as
much as $45 million in transition costs could be sought by these suppliers
through a series of FERC filings over the 12 to 24 month period that began on
June 1, 1993.  The largest element of the aforementioned transition costs
results from the pipelines' need to buy out gas supply contracts entered into
prior to Order 636.  The total amount of such costs ultimately billed to
Commonwealth Gas will vary depending on the success of the pipelines in
negotiating settlements with their former suppliers, and final review by the
FERC.  Commonwealth Gas is actively reviewing the prudency of transition costs
billed in order to minimize costs to its customers.  Commonwealth Gas has
recorded its estimated liability based on amounts incurred by the respective
pipelines as of December 31, 1993.

      On October 29, 1993, Commonwealth Gas received preliminary DPU
authorization to recover these costs, with carrying charges, through the CGA
over a four-year period that began in November 1993.  As a result, a
regulatory asset totaling $21.9 million, net of $400,000 recovered during the
fourth quarter, was recorded as of December 31, 1993 and reflected in deferred
charges.  In addition, a related liability of $13.1 million was reflected in
deferred credits.  Also, approximately $7.9 million of the amount paid to the
pipeline companies relates to gas inventory costs being allocated new storage
services under Order 636.  Commonwealth Gas will recover these inventory costs
through the CGA.

(3)   Income Taxes

      The system files a consolidated federal income tax return.  For
financial reporting purposes, the System and its subsidiaries provide taxes on
a separate return basis.

      The following is a summary of the consolidated provisions for income
taxes for the years ended December 31, 1993, 1992 and 1991.

      Effective January 1, 1992, the system adopted the provisions of
Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes" (SFAS No. 109).  SFAS No. 109 requires recognition of deferred tax
liabilities and assets for the expected future tax consequences of events that
have been included in the financial statements or tax returns.  Under this
method, deferred tax liabilities and assets are determined based on the
                                    PAGE 59

difference between the financial statement and tax basis of assets and
liabilities using enacted tax rates in effect in the year in which the
differences are expected to reverse.

      Accumulated deferred income taxes consisted of the following in 1993 and
1992:

deferred tax asset of $207,000 in 1993 and $8,062,000 in 1992 which was
included in prepaid income taxes in the accompanying Consolidated Balance
Sheets.

      The following table, detailing the significant timing differences for
1991, which resulted in deferred income taxes, is required to be disclosed
pursuant to accounting standards for income taxes in effect prior to adoption
of SFAS No. 109:

      The total income tax provision set forth on the previous page represents
38% in 1993, 23% in 1992 and 36% in 1991 of income before such taxes.  The
following table reconciles the statutory federal income tax rate to these
percentages:

      On April 22, 1992, Commonwealth Electric reached a settlement agreement
with the Attorney General of Massachusetts and a consumer group, which was ap-
proved by the DPU.  The settlement resulted in the issuance of an accounting
order authorizing its retention of $5.7 million in excess deferred taxes
subject to obtaining a favorable ruling from the Internal Revenue Service
which was received on November 30, 1992.

      In accordance with the above settlement agreement, Commonwealth Electric
wrote off in 1992 storm damage costs of $9.2 million ($5.7 million net of
tax).  The balance of the excess reserves that would have been returned to
customers was removed from the deferred tax reserve account and, after
adjustment to its pretax amount as required by SFAS 109, was credited to a
liability account.  The excess reserves/regulatory liability which Common-
wealth Electric would retain pursuant to the settlement agreement was also
removed from this liability account and credited to other income together with
the related income taxes.  These amounts were classified as income tax expense
and were used in the reconciliation of the income tax rate.

      As a result of the Revenue Reconciliation Act of 1993, the System's con-
solidated federal income tax rate increased to 35% effective January 1, 1993.

(4)  Employee Benefit Plans

      (a) Pension

      The system has a noncontributory pension plan covering substantially all
regular employees who have attained the age of 21 and have completed a year of
service. Pension benefits are based on an employee's years of service and
compensation. The system makes monthly contributions to the plan consistent
with the funding requirements of the Employee Retirement Income Security Act
of 1974.

      Components of pension expense and related economic assumptions were as
follows:
                                            1993        1992        1991

      Interest cost                         20,410      18,653      16,794

        compensation                        4.50        5.50        8.50

      Pension expense reflects the use of the projected unit credit method
which is also the actuarial cost method used in determining future funding of
the plan.  Commonwealth Electric and Cambridge, in accordance with current
rate-making, are deferring the difference between pension contribution, which
is allowed currently in base rates, and pension expense, recognized pursuant
to Statement of Financial Accounting Standards No. 87, "Employers' Accounting
for Pensions."  The funded status of the system's pension plan (using a
measurement date of December 31) is as follows:

                                                 1993          1992

                                               $(238,150)    $(177,675)

      Projected benefit obligation             $(288,309)    $(228,194)
      Plan assets at fair market value           268,672       239,849
      Projected benefit obligation less
        (greater) than plan assets               (19,637)       11,655
      Unamortized transition obligation           12,857        14,464
      Unrecognized prior service cost             14,524         9,442
      Unrecognized gain                          (20,905)      (46,136)
      Accrued pension liability                $ (13,161)    $ (10,575)

      Plan assets consist primarily of fixed income and equity securities.
Fluctuations in the fair market value of plan assets will affect pension
expense in future years.  The increase in the accumulated benefit obligation
and the projected benefit obligation from December 31, 1992 to December 31,
1993 was primarily due to a reduction of the discount rate in light of current
interest rates.

      (b)  Other Postretirement Benefits

      Through December 31, 1992, the system provided postretirement health
care and life insurance benefits to eligible retired employees.  Employees
became eligible for these benefits if their age plus years of service at
retirement equaled 75 or more provided, however, that such service was
performed for a subsidiary of the System.  As of January 1, 1993, the system
eliminated postretirement health care benefits for those non-bargaining
employees who were less than 40 years of age or had less than 12 years of
service at that date.  Under certain circumstances, eligible employees are now
required to make contributions for postretirement benefits.  Certain
bargaining employees are also participating under these new eligibility
requirements.

      Effective January 1, 1993, the system adopted the provisions of
Statement of Financial Accounting Standards No. 106, "Employers' Accounting
for Postretirement Benefits Other Than Pensions" (SFAS No. 106).  This new
standard requires the accrual of the expected cost of such benefits during the
employees' years of service and the recognition of an actuarially determined
postretirement benefit obligation earned by existing retirees.  The
assumptions and calculations involved in determining the accrual and the
accumulated postretirement benefit obligation (APBO) closely parallel pension
accounting requirements.  The cumulative effect of implementation of SFAS No.
106 as of January 1, 1993 was approximately $106.7 million which is being 
                                    PAGE 62

                          COMMONWEALTH ENERGY SYSTEM

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

amortized over 20 years.  Prior to 1993, the cost of postretirement benefits
was recognized as the benefits were paid.  The cost of retiree medical care
and life insurance benefits under the traditional pay-as-you-go method totaled
$4,738,000 during 1992 and $4,258,000 in 1991.

      In 1993, the system began making contributions to various voluntary
employee beneficiary association (VEBA) trusts that were established pursuant
to section 501(c)9 of the Internal Revenue Code (the Code).  The system also
made contributions to a subaccount of its pension plan pursuant to section 401
(h) of the Code to satisfy a portion of its postretirement benefit obligation. 
The system contributed approximately $12,600,000 to these trusts during 1993.

      The net periodic postretirement benefit cost for the year ended
December 31, 1993 included the following components:

                                                              1993
                                                    (Dollars in Thousands)
      Service cost                                          $ 2,100
      Interest cost                                           9,017
      Return on plan assets                                    (661)
      Amortization of transition obligation over 20 years     5,336
      Net amortization and deferral                              30

         Net postretirement benefit cost                    $ 4,990

      The funded status of the system's postretirement benefit plan using a
measurement date of December 31, 1993 is as follows:

                                                              1993

      In determining its estimated APBO and the funded status of the plan, the
system assumed a discount rate of 7.25%, an expected long-term rate of return
on plan assets of 8.5%, and a medical care cost trend rate of 9%, which
gradually decreases to 5% in the year 2007 and remains at that level
thereafter.  The estimate also reflects a trend rate of 14.9% for
reimbursement of Medicare Part B premiums which decreases to 5% by 2007 and a
dental care trend rate of 5% in all years.  A one percent change in the
medical trend rate would have a $1.7 million impact on the system's annual
expense (interest component - $1.2 million; service cost - $500,000) and would
change the transition obligation by approximately $14.5 million.

      Plan assets consist primarily of fixed income and equity securities.
Fluctuations in the fair market value of plan assets will affect
postretirement benefit expense in future years.

      The DPU's policy on postretirement benefits is to allow in rates the
maximum tax deductible contributions made to trusts that have been established
specifically to pay postretirement benefits.  Effective with its June 1, 1993
rate order from the DPU, Cambridge was allowed to recover its SFAS No. 106
expense in base rates over a four-year phase-in period with carrying costs on
the deferred balance.  The other System companies intend to seek recovery in
                                    PAGE 63


                          COMMONWEALTH ENERGY SYSTEM

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

their next rate proceeding.  While the system is unable to predict the outcome
of these rate proceedings, it believes the DPU will authorize similar rate
treatment as provided to Cambridge and other Massachusetts electric and gas
companies for the recovery of the cost of these benefits.  Further, based on
recent DPU action and discussions with regulators, the system believes that it
is appropriate to record the difference between the amount included in rates
and SFAS No. 106 costs as a regulatory asset.  At December 31, 1993, this
deferral amounted to approximately $8.9 million.

      (c) Savings Plan

      The system has an Employees Savings Plan that provides for system
contributions equal to contributions by eligible employees of up to four
percent of each employee's compensation rate.  Effective January 1, 1993, the
rate was increased to five percent for those employees no longer eligible for
postretirement benefits other than pensions.  The total system contribution
was $4,245,000 in 1993, $4,134,000 in 1992 and $3,903,000 in 1991. 

(5)  Interim Financing and Long-Term Debt

      (a)  Notes Payable to Banks

      System companies maintain both committed and uncommitted lines of credit
for the short-term financing of their construction programs and other
corporate purposes.  As of December 31, 1993, system companies had $115
million of committed lines of credit that will expire at varying intervals in
1994.  These lines are normally renewed upon expiration and require annual
fees of up to .1875% of the individual line.  At December 31, 1993, the
uncommitted lines of credit totaled $70 million.  Interest rates on the
outstanding borrowings generally are at an adjusted money market rate.  Notes
payable to banks totaled $71,975,000 and $165,600,000 at December 31, 1993 and
1992, respectively.

      (b)  Long-Term Debt Maturities and Retirements

      Under terms of various indentures and loan agreements, the System and
certain subsidiary companies are required to make periodic sinking fund
payments for retirement of outstanding long-term debt.  These payments and
balances of maturing debt issues for the five years subsequent to December 31,
1993 are as follows:

                    Sinking Funds    Maturing Debt Issues

      1998               7,653        10,000      9,000       26,653

(6)   Redeemable Preferred Shares

      Each series of the System's preferred shares was issued at par value,
$100 per share, and is subject to periodic, mandatory sinking fund payments.
The System can make additional voluntary redemptions, not exceeding the
required redemption, at par, on a non-cumulative basis, on each sinking fund
date.

      Preferred shares may also be called for redemption, in whole or in
part, in excess of the required and voluntary sinking fund redemptions.  The
obligation to make mandatory redemptions is cumulative and the System is not
allowed to pay dividends to common shareholders or make optional sinking fund
                                    PAGE 64


                          COMMONWEALTH ENERGY SYSTEM

payments if mandatory redemptions are in arrears.  Details of redemptions for
each series are contained in the following table:

                                   Sinking Funds          Optional
                  Dividend           1994-1998           Redemption

      Series A     4.80%        $120          $120          $102
      Series B     8.10          160           160           101
      Series C     7.75          540           540           101

      Preferred shareholders have no voting rights except in the event that
six full quarterly dividends have not been paid.  In this circumstance, the
preferred shareholders are entitled, voting as a class, to elect two of the
nine Trustees of the System.

      The preference of these shares in involuntary liquidation is equal to
par value.  The shares are of equal rank and are entitled to cumulative
dividends at the annual rate established for each series.  No dividend can be
declared on any series unless proportionate dividends are concurrently
declared on the other outstanding series and in the event that dividend
payments are in arrears, the System may not redeem any shares unless all
shares of all preferred series are redeemed.

(7)   Disclosure About Fair Value of Financial Instruments

      As required by Statement of Financial Accounting Standards No. 107,
"Disclosures about Fair Value of Financial Instruments," the fair value of
certain financial instruments included in the accompanying Consolidated
Balance Sheets as of December 31, 1993 and 1992 are as follows:


                                  1993                  1992   
                                     (Dollars in Thousands)

                           Carrying    Fair       Carrying    Fair  
                             Value    Value         Value    Value  

    Long-Term Debt         $464,866  $526,405     $373,485  $411,241
    Preferred Stock          16,300    15,759       17,120    16,026

      The carrying amount of cash and notes payable to banks approximates the
fair value because of the short maturity of these financial instruments.

      The estimated fair value of long-term debt and preferred stock are based
upon quoted market prices of the same or similar issues or on the current
rates offered for debt or preferred shares with the same remaining maturity. 
The fair values shown above do not purport to represent the amounts at which
those obligations would be settled.

(8)   Lease Obligations

      System companies lease property, transmission facilities and equipment
under agreements, some of which are capital leases. Several subsidiaries
renegotiate certain lease agreements annually.  These new agreements are for a
term of one year and are renewable monthly thereafter.  COM/Energy Services
Company has agreements in effect for office furniture, computer,
transportation and other equipment.  Generally, these agreements require the
lessee to pay related taxes, maintenance and other costs of operation. Leases
currently in effect contain no provisions which prohibit system companies from
entering into future lease agreements or obligations.

retained earnings was restricted against the payment of cash dividends by
terms of indentures and note agreements securing long-term debt.

(10)  Energy Park Development

      As a result of unsuccessful efforts to develop an energy park, the
System announced on January 23, 1992 its decision to write down its investment
in the Freetown Energy Park project.  This action resulted in the recognition
of a charge (net of tax) in 1991 of $14.8 million recorded by COM/Energy
Freetown Realty, a wholly-owned subsidiary of the System.

(11)  Segment Information

      System companies provide electric, gas and steam services to retail
customers in communities located in central and eastern Massachusetts and, in
addition, sell electricity at wholesale to Massachusetts customers.  Other
operations of the system include the development and operation of rental
properties and other activities which do not presently contribute
significantly to either revenues or operating income.

      Operating income of the various industry segments includes income from
transactions with affiliates and is exclusive of interest expense, income
taxes and equity in earnings of unconsolidated corporate joint ventures.
