                        COMMONWEALTH ENERGY SYSTEM

                                  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. (Hopkinton);
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 wrote down its investment in the Freetown project and
plans to sell the property.

      Each of the operating utility subsidiaries serves retail customers
except for Canal Electric Company (Canal) which operates an electric
generating station located 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 expenses.  In October 1993, Canal reached an agreement
with Montaup and Algonquin Gas Transmission Company to build a natural gas
<PAGE>
<PAGE 4>


                        COMMONWEALTH ENERGY SYSTEM

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 308,000 year-round and 49,000 seasonal customers in 41
communities in eastern Massachusetts covering 1,112 square miles and having an
aggregate population of 645,000.  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.

      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 one
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 its largest customers.  Genzyme's
steam need for 1995 is estimated to be 83.3 million pounds, which represents
approximately 5% of steam unit sales, for heating, air conditioning and
testing processes.  In 1996, Genzyme's annual requirement is estimated to
reach approximately 175 million pounds based upon the expectation of
commercial manufacturing of a biotherapeutic product in 1995.

      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 (Harvard) and the Massachusetts Institute of Technology (MIT).

      MIT has completed construction of a 19 MW natural gas-fired cogeneration
facility which is expected to be in operation in 1995.  MIT anticipates this
cogeneration facility will meet approximately 94% of its power, heating and
cooling requirements.  Sales to MIT in 1994 accounted for approximately 1.8%
of total unit sales.  MIT and Cambridge Electric were unsuccessful in attempts
to reach agreement on the cost to provide back up and supplemental service. 
In March 1995, Cambridge Electric filed four rate schedules with the
Massachusetts Department of Public Utilities (DPU) which, in part, seek to
recover costs incurred to serve large customers such as MIT.  These rates 
<PAGE>
<PAGE 5>


                        COMMONWEALTH ENERGY SYSTEM

include costs associated with providing standby, maintenance and supplemental 
service on an ongoing basis as well as a customer transition charge to recover
other costs incurred to serve its largest customers should they discontinue
service with Cambridge Electric while remaining in Cambridge.

      In March 1994, Cambridge Electric was successful in negotiating a seven-
year service agreement with another large customer, Harvard, whose sales in
1994 accounted for approximately 1.6% of the System's total unit sales.

      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
1,046.5 MW at December 31, 1994.  Including 560 MW provided by Canal Unit 1,
of which three-quarters (420 MW) is sold to neighboring utilities under long-
term contracts, and 292.0 MW provided by Canal Unit 2. Another 145.1 MW is
provided by various smaller system units.  Of the 577.1 MW available to the
system, 77.6 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 8.9
MW.  In 1991, Canal executed a transaction with Central Vermont Public Service
Corporation (CVPS) whereby 50 MW of Canal Unit 2 was exchanged for 25 MW each
of CVPS's entitlement in the Vermont Yankee nuclear power plant and the
Merrimack 2 coal-fired unit through October 1995.  Additionally, in 1993,
Canal extended an agreement with New England Power Company (NEP) whereby 50 MW
of Canal Unit 2 (previously 20 MW) is exchanged for 50 MW of Bear Swamp Unit
Nos. 1 and 2 through April 1997.  The Bear Swamp Units are pumped storage
hydro electric generating facilities. These contracts are designed to reduce
the system's reliance on oil.

      In addition, through Canal's equity ownership in Hydro-Quebec Phase II,
the system has an entitlement of 67.9 MW.  Purchase power arrangements were
also in place with the following natural gas-fired cogenerating units in
Massachusetts: 23 MW from Lowell Cogeneration Company Limited Partnership
(Lowell), 38 MW from Pepperell Power Associates Limited Partnership
(Pepperell), 53.0 MW from Northeast Energy Associates, 59.9 MW from Masspower
and 58.9 MW from Altresco Pittsfield.  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 in May 1993); has entitlements totaling 24.4
MW through contracts with five (5) hydroelectric suppliers, including 20 MW
from Boott Hydropower, Inc., in Lowell, Massachusetts; and also receives 68.2
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 system generation, including purchasing

<PAGE 6>


                        COMMONWEALTH ENERGY SYSTEM

available capacity from neighboring utilities and/or non-utility generators. 
Effective January 1, 1995, the system negotiated a restructured power sale
agreement with Lowell and terminated the Pepperell power sale agreement
through a buy-out arrangement, effective January 27, 1995.

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

                          Connecticut     Maine   Vermont

       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.

       One of the operating nuclear units, located in Wiscasset, Maine and
operated by Maine Yankee Atomic Power Company, has been experiencing
degradation of its steam generator tubes, principally in the form of
circumferential cracking, which until early 1995 was believed to be limited to
a relatively small number of tubes.  During a refueling and maintenance outage
that began in early February 1995, Maine Yankee, through the use of new
inspection methods, detected increased degradation of the tubes well above its
expectations.  Maine Yankee is currently evaluating alternative courses of
action to remedy this situation, most of which could result in significant
capital expenditures and an extended outage period.  At this time, Cambridge
Electric cannot predict what action will be needed to rectify the situation,
the costs to be incurred or the length of the outage.  The Board of Directors
of Maine Yankee will be meeting in early April 1995 to consider various
options.

       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).  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.  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.
<PAGE>
<PAGE 7>


                        COMMONWEALTH ENERGY SYSTEM

       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 is accomplished by use of computers to monitor and
forecast load requirements.

       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
(referred to as the Hydro-Quebec Project-Phase I and Phase II) 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.  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.

       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 $13.8 million at December 31,
1994.  In addition, Canal has an equity interest in Phase II which amounted to
$3.8 million in 1994 and $3.9 million in 1993.

       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.

       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.  For additional information concerning system commitments
under long-term power contracts, refer to Note 2(d) of Notes to Consolidated
Financial Statements filed under Item 8 of this report.

       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
Cambridge Electric and Commonwealth Electric.  For additional information

                        COMMONWEALTH ENERGY SYSTEM

concerning Seabrook 1, refer to Note 2(b) of Notes to Consolidated Financial
Statements filed under Item 8 of this report.

       Electric Fuel Supply

       (a) Oil

       Imported residual oil is the fuel used in the generation of power in
system generating plants, producing approximately 24% of the system's total
energy requirement for 1994.

       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.  Through December 31, 1994, approximately
16% of Canal's total requirements have been met by lower-cost spot purchases.

       Energy Supply and Credit Corporation (ESCO) operates Canal's oil
terminal and manages 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 1994, ESCO maintained an average daily inventory of 575,000 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.

       Reference is made to Item 7, "Management's Discussion and Analysis of
Financial Condition and Results of Operations," for a discussion of the cost
of fuel oil.

       (b) Nuclear Fuel Supply and Disposal

       Approximately 25% of the system's total energy requirement for 1994 was
generated by nuclear plants.  The nuclear fuel contract and inventory informa-
tion 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.  Seabrook's requirement for nuclear 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
or a monitored retrievable storage facility.  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
<PAGE>
<PAGE 9>


                        COMMONWEALTH ENERGY SYSTEM

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 reassessment 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 accumulated through at least the
year 2010.

       Gas Supply

       In April 1992, the Federal Energy Regulatory Commission (FERC) issued
Order No. 636 (Order 636) which became effective on November 1, 1993.  The
order requires interstate pipelines to unbundle existing gas sales contracts
into separate components (gas sales, transportation and storage services) and
to provide transportation services that allow customers to receive the same
level and quality of service they had with the previous bundled contracts. 
Prior to the implementation of Order 636 Commonwealth Gas purchased the
majority of its gas supplies from either Tennessee Gas Pipeline Company
(Tennessee) or Algonquin Gas Transmission Company (Algonquin), supplemented
with third-party firm gas purchases, storage services, and firm transportation
from various pipelines.  Presently, Commonwealth Gas purchases only
transportation, storage, and balancing services from these pipelines (and
other upstream pipelines that bring gas from the supply wells to the final
transporting pipelines) and procures all of its gas supplies from third-party
vendors, utilizing firm contracts with terms ranging from less than one year
to three or more years.  The vendors vary from small independent marketers to
major gas and oil companies.  For additional information on Order 636, refer
to Note 2(g) of Notes to Financial Statements filed under Item 8 of this
report.

       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 and new agreements which are the result of Order 636
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 1994, over 98% of the gas utilized by Commonwealth Gas was
delivered by the interstate pipeline system, the remaining small quantity
(approximately 662,000 MMBTU) was delivered as liquid LNG from Distrigas of
Massachusetts.

       Commonwealth Gas entered into a multi-party agreement in 1992 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 eleven customers using this transpor-
tation service, accounting for 2,208 BBTU (4.5%) of system throughput in 1994.

                        COMMONWEALTH ENERGY SYSTEM

       Hopkinton LNG Facility

       A portion of Commonwealth Gas' 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 ex-
tending 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,
Commonwealth Gas 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
jurisdiction of the DPU, which regulates retail rates, accounting, issuance of
securities and other matters.  In addition, Canal, Cambridge Electric and
Commonwealth 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 reflect the costs
associated with postretirement benefits other than pensions which were
determined in accordance with Statement of Financial Accounting Standards No.
106, "Employers' Accounting for Postretirement Benefits Other Than Pensions,"
adopted as of January 1, 1993.  The DPU authorized full recovery of these
costs over a four-year phase-in 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.
<PAGE>
<PAGE 11>


                        COMMONWEALTH ENERGY SYSTEM

       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%.

       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 new rates went into effect
on November 1, 1991.

       In May 1994, Commonwealth Gas requested the DPU to change the backup
service charges under its firm transportation rate.  Back up charges result
when Commonwealth Gas sells gas from its system supplies to a customer whose
off-system gas supply has failed or is temporarily unavailable for causes
beyond the customer's control.  The change involved an upward indexing based
on changes in the gas supply demand costs occasioned by Order 636.  On
December 22, 1994, the DPU approved Commonwealth Gas' requested change
effective January 1, 1995.  This change, which has no effect on revenue,
results in a more equitable recovery of pipeline capacity costs between
Commonwealth Gas' total requirements and transportation customers.

       (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.

       During March of 1993, Cambridge Electric and Belmont signed a net
requirements power supply agreement, the terms and conditions of which
required Belmont to pay for all costs except transmission fees which Cambridge
Electric and Belmont attempted to negotiate.  The negotiations were not
successful and Cambridge Electric filed for approval of transmission rates
with the FERC on June 29, 1994.  The FERC accepted the rates effective January
25, 1995, subject to refund.  At the same time, an investigation was opened by
the FERC to determine the reasonableness of both the existing and the proposed
transmission rates charged to Belmont.  Cambridge Electric filed its case with
the FERC on October 25, 1994 and hearings are scheduled to begin during the
second quarter of 1995.

       (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.
<PAGE>
<PAGE 12>


                        COMMONWEALTH ENERGY SYSTEM

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, the companies 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 future consideration.  The companies have been involved in discussions
with interested parties in an effort to resolve this issue in a positive
fashion and hope to reach an agreement in the near future.

       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.

           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
<PAGE>
<PAGE 13>


                        COMMONWEALTH ENERGY SYSTEM

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 issues
are pending before the DPU.

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

       Commonwealth Gas is obligated, as part of its pipeline transportation
and supplier gas purchase contracts, to pay monthly demand charges which are
recovered 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.  There are still some small on-going amounts of take-or-pay costs
being collected by the pipeline, however, Tennessee has nearly reached the cap
of allowable collections under the settlement.

       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 to $2.5
million.  In addition, a settlement was reached with Koch Gateway Pipeline
(formerly the United Gas Pipeline) whereby Commonwealth Gas received
approximately $2 million in refunds for take-or-pay costs allocated through
Texas Eastern and Algonquin since 1985.  This amount is currently being
refunded to firm customers through the CGA.

       Commonwealth Gas is collecting all contract restructuring costs from
its customers through the CGA as permitted by the DPU.

       Competition

       This past year, the system continued to develop and implement
strategies to deal with the increasingly competitive environment in our gas
and electric businesses.  The inherently high cost of providing energy
services in the Northeast has placed the region at a competitive disadvan-
tageas more customers begin to explore alternative supply options.  Many state
and federal government agencies are considering implementing programs under
which utility and non-utility generators can sell electricity to customers of
other utilities without regard to previously closed franchise service areas. 
In 1994, the DPU began an inquiry into incentive rate-making and in February
1995 opened an investigation into electric industry restructuring.

                        COMMONWEALTH ENERGY SYSTEM

       Actions by system companies in response to the new competitive
challenges have been well received by regulators, business groups and
customers.  For a more detailed discussion of competition and the programs
currently in place within the system, refer to the "Competition" section of
Management's Discussion and Analysis of Financial Condition and Results of
Operation filed under Item 7 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 10
of Notes to Consolidated Financial Statements filed under Item 8 of this re-
port.

       Environmental Matters

       The system is subject to laws and regulations administered by federal,
state and local authorities relating to the quality of the environment. 
System compliance with these laws and regulations will require capital
expenditures of $41.8 million from 1995 through 1999 for the electric and gas
divisions.

       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 2.2% to
2,169 in 1994 from 2,217 employees at year-end 1993.  Of the current total,
1,282 (59%) are represented by various collective bargaining units.  Existing
agreements are for varying periods and expire in 1995 and thereafter. 
Employee relations have generally been satisfactory.

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
<PAGE>
<PAGE 15>


                        COMMONWEALTH ENERGY SYSTEM

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 which ceased operations in October 1992
and was abandoned in 1993.

        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 8.9 MW joint-ownership interest in Central Maine Power Company's Wyman Unit
4.  The system also has an interest in smaller generating units totaling 77.6
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.

        At December 31, 1994, the electric transmission and distribution
system consisted of 5,790 pole miles of overhead lines, 4,192 cable miles of
underground line, 355 substations and 374,055 active customer meters.

        The principal natural gas properties consist of distribution mains,
services and meters necessary to maintain reliable service to customers.  At
the end of 1994, the gas system included 2,761 miles of gas distribution
lines, 162,971 services and 239,302 customer meters together with the
necessary measuring and regulating equipment.  In addition, the system owns a
liquefaction 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.

Item 3. Legal Proceedings

        The system is subject to legal claims and matters arising from its
course of business, including its participation in power contract arbitrations
as discussed in the "Power Contract Arbitrations" section of Management's
Discussion and Analysis of Financial Condition and Results of Operations filed

                   Notice of Annual Meeting of Shareholders

                                  May 4, 1995

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 4, 1995, 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 6 of the System's Declaration of Trust, as amended, to
            revise the geographic residency requirement for Trustees.

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

      4.    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 17, 1995
are entitled to notice of, and to vote at, the meeting.

                                          By order of the Trustees, 




                                          MICHAEL P. SULLIVAN
                                          Michael P. Sullivan
                                          Vice President, Secretary 
                                          and General Counsel

March 31, 1995

                                   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
Commonwealth Energy System, P.O. Box 9150, Cambridge, Massachusetts 02142-
9150.

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 4, 1995, 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. 
Abstentions 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 purpose of determination
of a quorum or for the purpose 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
March 31, 1995.

                             FINANCIAL STATEMENTS

(1) Beneficial ownership set forth in this Proxy Statement includes, where
    applicable, shares with respect to which voting or investment power is
    attributed to an Executive Officer or Trustee because of joint or
    fiduciary ownership of the shares or relationship of the Executive Officer
    or Trustee to the record owner, such as a spouse, together with shares
    held under the Employees Savings Plan of Commonwealth Energy System and
    Subsidiary Companies.

                   MATTERS TO BE BROUGHT BEFORE THE MEETING

                            1-ELECTION OF TRUSTEES

      Three Trustees will be elected at the Annual Meeting of Shareholders to
hold office for the ensuing three years in accordance with the Declaration of
Trust, which provides for staggered terms of Trustees of three years each. 
The three Trustees elected at this meeting will hold office for a three-year
term and until the election and qualification of their respective successors. 
Under the terms of the Declaration of Trust, Trustees are required to be
elected by a plurality vote of the Shareholders.

      The Shares represented by the enclosed form of proxy will be voted, and
the persons named in such form of proxy will, unless otherwise directed in the
proxy, vote shares represented by proxies received for the election of the
following nominees:

                              Sheldon A. Buckler
                               Betty L. Francis
                             Michael C. Ruettgers

      Of the three nominees, Dr. Buckler and Ms. Francis are presently
Trustees. Mr. Ruettgers was nominated by the Board on February 23, 1995 to
fill a vacancy which will be occasioned by the retirement of Mr. Sinclair
Weeks, who is retiring from the Board at the conclusion of his term effective
May 4, 1995.

      Although it is not contemplated that any of the three (3) nominees will
be unable to serve, in the event a vacancy in the list of the System's
nominees is occasioned by death or other unexpected occurrence, your proxy
will be voted for the election of a nominee acceptable to the remaining
Trustees.

--------------------

(1)   The amounts in this column represent the aggregate total of cash
      compensation received and compensation deferred by the above-named
      individuals.  Compensation is deferred pursuant to the provisions of the
      Employees Savings Plan and the Executive Salary Continuation and Excess
      Benefit Plan of Commonwealth Energy System and Subsidiary Companies.

(2)   The dollar value of perquisites and other personal benefits, securities
      or property totalling either $50,000 or 10% of total annual salary and
      bonus, together with various other earnings, amounts reimbursed for the
      payment of taxes, and the dollar value of any stock discounts not
      generally available are required to be disclosed in this column.  In
      1994, there were no such perquisites, earnings, reimbursements or
      discounts paid or made.

(3)   In 1994, the System did not provide to its employees, including
      Executive Officers, any payments or awards in the 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 1994 on behalf of the
      above-named individuals to the Employees Savings Plan and 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.  Of the amounts set forth in the "All Other
      Compensation" column, $6,162, $8,400, $4,622, $2,311 and $2,887
      represent the contributions made on behalf of Messrs. Poist, Wright,
<PAGE>
<PAGE 8>


      Margossian, Rappoli and Devanna, respectively, by the Employees Savings
      Plan.  Contributions made on behalf of Messrs. Poist, Wright,
      Margossian, Rappoli and Devanna by the Executive Salary Continuation and
      Excess Benefit Plan in 1994 equalled $6,642, $0, $2,518, $3,569 and
      $4,139, respectively.

(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 1994, the
      maximum annual compensation limit under the Pension Plan for Employees
      of Commonwealth Energy System and Subsidiary Companies was $150,000, and
      the maximum annual benefit under that Plan was $118,800.
</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, Rappoli and Devanna have 30,
27, 25, 20 and 13 credited years of service respectively. For the purposes of
calculating the annual retirement benefits of Messrs. Poist, Wright,
Margossian, Rappoli and Devanna pursuant to the Plan, only the amounts set
forth in the summary compensation table as "Salary" are utilized to determine
each executive's three highest consecutive January 1 base salaries during the
ten year period preceding the executive's retirement or termination.

      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
<PAGE>
<PAGE 10>


thirty-five percent of final base salary per year for life, or for a period of
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 1994:

      The Chief Executive Officer's base salary compensation is determined by
review of comparable utility salary data and evaluation of certain reference
criteria.  The Executive Compensation Committee (the "Committee") reviews
compensation comparisons prepared by an independent consultant for roles
comparable in scope to the Chief Executive Officer's and other executives.  In
addition, the Committee reviews market compensation data provided by the
System's human resources department, selected utility proxy material, and
utility industry references such as those provided by the Edison Electric
Institute.  Among the reference criteria reviewed by the Committee in
developing external market pay norms are business type (investor-owned
utilities), scope (utilities with revenues of approximately $500 million to $2
billion) and location (utilities headquartered in the northeast region of the
U.S.).  This market reference group of companies represents a subset of Value
Line's utility sample.

      The Chief Executive Officer's base salary target (i.e., control point)
is designed to match the market median for the utility reference group.  The
Committee adjusts the Chief Executive Officer's salary in relation to the
salary range target on a subjective basis through evaluation of the same
objective criteria used to determine the Chief Executive Officer's annual
incentive award and individual goals as set forth below.

      The Chief Executive Officer's award for 1994 pursuant to the System's
Annual Incentive 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 1994, the System
criteria forming the goals and objectives applicable to the Annual Incentive
Plan were: 1) meeting pre-established targets comparing System actual net
income to budgeted net income for 1994; 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 utility 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
actual net income was to meet or exceed the approved budgeted amounts.  The
System's 1994 net income of $48.97 million exceeded targeted net income of
$41.20 million by 18.9%, resulting in a maximum award.  The goal established
for cost control was for operating and maintenance expenses in 1994 to be
below the approved budgeted amounts.  This goal was achieved by the System
having reduced actual operation and maintenance expenses to 5.3% 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, as the System was rated the seventh most
effective of the 19 companies in controlling operation and maintenance
expenses.  In the aggregate, the goals and objectives applicable to the System
component of the Annual Incentive Plan were rated as 95.8% achieved.
<PAGE>
<PAGE 11>


      The individual goals of the Chief Executive Officer for 1994 under the
Annual Incentive Plan included:  developing a System business development
plan, overseeing the formation of a key performance factor metering system,
and improving electric operations' overall customer favorability as measured
by customer surveys.  The Chief Executive Officer's performance relative to
achieving individual goals was rated as 90% achieved, resulting in an
aggregate performance rating of 94% achievement.

      The System's Long Term Incentive Plan, approved by shareholders in 1994,
measures performance and provides the potential for awards of Common Shares
over a three-year Plan Period.  The first year of the initial Plan Period
established under that Plan was 1994, and as a result no award was made under
the Plan for 1994. 

      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.  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 Annual Incentive Plan to receive annual variable incentive
compensation of up to a maximum of 30% of annual base salary. In 1994, 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 Annual Incentive 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 management of outside
legal services, the stabilization of electric customers' costs of purchased
power, 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 1994. 
The Board has an Audit Committee, an Executive Compensation Committee, a
Nominating Committee, a Benefit Review Committee and a Strategic Planning
Committee.

      The Audit Committee is composed of Betty L. Francis, Chairperson, Peter
H. Cressy and William J. O'Brien.  The Committee held four meetings in 1994. 
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 1994 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
two meetings in 1994.  The functions of the Committee are:  to coordinate
suggestions or searches for potential nominees for the position of Trustee;
<PAGE>
<PAGE 14>


to review and evaluate qualifications of potential nominees; and to recommend
to 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 1994 the Committee
held one meeting.  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.

      The Strategic Planning Committee is composed of Gerald L. Wilson,
Chairperson and Sheldon A. Buckler.  The Committee held seven meetings during
1994.  The functions of this Committee are:  attendance at strategic planning
sessions, support and insight to management and coordination and communication
of management planning activities with the Board of Trustees.

      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 $850 for
each Trustee and Committee meeting attended.  The Chairpersons of the Audit,
Executive Compensation, Benefit Review and Strategic Planning Committees each
receive an additional $1,000 during the year.  In addition, the Chairman of
the Board receives a retainer of $10,000 per year 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 is payable to Trustees for a period equal to the greater of
ten years or the number of years of service as a Trustee.


                        2-AMENDMENT TO SECTION 6 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 6 of the System's Declaration
of Trust, which section contains the requirement that at least two-thirds of
the Trustees be at all times residents of Massachusetts and that each of the
remaining Trustees be a resident of one of the New England states.  The
purpose of the amendment is to remove the restriction which requires that each
of the Trustees who are not Massachusetts residents be a resident of one of
the New England states.  The text of the proposed amendment to section 6 is
set forth as follows:

      Section 6 of the System's Declaration of Trust would be amended by
deleting from the second and third lines of the first paragraph of Section 6
the words "and each of the remaining Trustees shall at all times be a resident
of one of the New England states" so that the first sentence of section 6
reads as follows:

      "At least two-thirds of the Trustees hereunder shall at all times be
residents of Massachusetts".
<PAGE>
<PAGE 15>


      The Trustees believe that this amendment would be in the best interests
of Shareholders, as it will enable the System to attract and retain qualified
candidates for the position of Trustee throughout the System's geographic
shareholder base, which includes all of the United States.  At the same time,
retention of the Massachusetts residency requirement for two-thirds of the
Board reflects the fact that the System is predominantly an intra-state
Massachusetts gas and electric utility company.  The proposed amendment will
also allow for the continued service on the Board by Ms. Francis, who has
taken a position in the Jacksonville, Florida office of BancBoston Mortgage
Corporation.

      The Board of Trustees believes that the restrictions relative to
residency which were inserted into the Declaration of Trust over forty years
ago no longer reflect the System's shareholder demographics, and that such
restrictions both limit the selection and retention of Trustees and fail to
provide for the mobility of today's workforce.  At the same time, the
provisions set forth in section 6 requiring two-thirds of the Trustees to be
residents of Massachusetts will continue to ensure that the Board has a
majority of members who are aware of the business climate within which the
System operates so as to be able to provide valuable insight and advice in the
management of the System's affairs.  Upon the consent of the holders of the
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 4,
1995 vote to amend the Declaration of Trust and will file the amended
Declaration of Trust, 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-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 1995 Annual
Meeting:

      RESOLVED: It is the judgment of the Shareholders of Commonwealth Energy
System ("CES") that it is advisable to amend the CES Declaration of Trust,
dated December 31, 1926, as amended, and that the Board of Trustees present to
Shareholders at the next Annual Meeting of Shareholders an appropriate
amendment to said Declaration of Trust to accomplish the following:

Trustees elected at the annual meeting of Shareholders commencing with the
1997 Annual Meeting of Shareholders shall be elected to hold office until the
next annual meeting and until their successors are elected and qualified.

      SUPPORTING STATEMENT:  This is a reasonable proposal.  It has been
considered Annually at CES Shareholder Annual Meetings starting with 1991.

It provides for the appropriate modification to the Declaration of Trust in
1996, the election of ALL Trustees ANNUALLY commencing in 1997, in a carefully
thought out manner.  This proposal at the May 05, 1994 Annual Meeting of
Shareholders received as follows:
1,483,947 Common Shares or 14% were voted "For" the Proposal
5,917,813 Common Shares or 57% were voted "Against" the Proposal, and
3% "Abstained" from the Proposal.
System Vice President, General Counsel, and Secretary, Mr. Michael P.
Sullivan, Esquire, has advised Proponent that based on this vote and the
applicable regulations Proponent may bring forth the Proposal again.
A proposal to abolish the Classified Board of Directors of Tri-Continental
Corporation, presented by this proponent May 19, 1994 at Chemical Bank, New
York City, received the following votes as reported to Proponent:
<PAGE>
<PAGE 16>


48,067,020 shareholders representing 59.8% of the shares outstanding &
eligible to vote balloted in person or by proxy ballot.
20.0% of the shares outstanding and 33.5% of the votes cast voted "For"
Proponent's proposal.
35.9% of the shares outstanding and entitled to vote and 60.9% of the
shareholder votes cast voted "Against" proponent's proposal.
And, 3.9% of the shares outstanding and entitled to vote and 6.5% of votes
cast votes "Abstained."
Objections of TY were that a classified board:  provides continuity,
stability, and experience in leadership and in direction strategy...; ensures
Board Members will be fully accountable to Stockholders because each year a
portion of the Board must stand before Stockholders for election...; improves
the ability of Board Members to more effectively represent the interests of
all Stockholders.
The reactions of CES Shareholders and other Shareholders points out the
necessity for CES Shareholders to vote again on Board declassification.

      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
1996 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 ensure
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.

      The Board continues to believe 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 1996 Annual Meeting of
Shareholders) requires the affirmative vote or written consent of three-
quarters of the shares entitled to vote, in accordance with the terms of the
System's Declaration of Trust.
<PAGE>
<PAGE 17>


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

                               4-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 LLP.  It is expected that
representatives of Arthur Andersen LLP 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 $5,500 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 1996 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, 1995.

      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.

        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.

      1994 versus 1993

      In 1994, earnings improved by 7.2% to the highest year-end level in the
history of the System.  Return on average common equity for 1994 was 13.7%,
equaling the return for 1993, which was the highest since 1985.  Significant
factors that contributed to the improved earnings were: 1) cost savings of
$2.7 million in direct payroll and the absence in 1994 of $3.7 million in
severance pay attributable to a work force reduction implemented at our
electric division and services company during the second quarter of 1993;    
2) reduced undercollection of certain purchased power capacity costs that
resulted in a positive earnings change of $2.9 million; 3) a full year of new
base rates for Cambridge Electric Light Company that became effective in June
1993; 4) an increase of 1.4% in retail electric unit sales; and 5) lower
short-term interest costs of $2.3 million reflecting a 38% decrease in the
debt level to $44.9 million (the lowest year-end amount since 1986 and only
5.2% of total capitalization).

      The higher earnings in 1994 were achieved despite the decline in
earnings from gas operations that reflected milder weather conditions in the
fourth quarter when degree days were 14% below both normal and the fourth
quarter of the prior year.  For the year, firm gas sales decreased 1.7% but
several record daily send-outs were achieved, including a new peak on January
19, 1994 of 364,799 MMBTU.

      1993 versus 1992

      Earnings improved in 1993 by 15.5% due, in part, to a significant
reduction in other operation expense ($16.6 million or 7.4%) that reflected
the system's cost containment efforts which included the shutdown of the
Cannon Street generating station in late 1992 ($1.5 million) and the work
force reduction that provided a net payroll savings of $1.6 million.  The
provision for bad debt expense declined by $2.7 million and resulted from
improved collection experience.  Other factors which contributed to the
earnings increase were: 1) higher retail electric unit sales and firm gas
sales during the heating season; 2) new base rates for Cambridge Electric;     
3) the recognition of electric conservation and load management (C&LM) related
lost base revenues ($2.4 million); and 4) the reversal of a reserve ($3.8
million) following the resolution of uncertainties related to the system's
Seabrook investment.

      In 1994, electric operating revenues increased $15.1 million (2.4%) due
primarily to higher fuel and purchased power costs of $11 million (3.2%), the
new base rates for Cambridge Electric that became effective June 1, 1993 and
higher total unit sales of 2.2%.  Another factor contributing to the increased
level of revenues was a greater recovery of lost base revenues of approximate-
ly $920,000.  Partially offsetting these increases was a $1.5 million reduc-
tion in C&LM program costs for electric operations which are being recovered
through revenues.  To the extent that costs associated with these programs
increase or decrease from period to period, a corresponding change will occur
in revenues.  The recovery of lost base revenues is allowed by the Massachu-
setts Department of Public Utilities (DPU) to encourage effective implementa-
tion of C&LM programs.  The rise in wholesale revenues of $2.7 million (2.6%)
was due to a $9.3 million (12.8%) increase in sales to other utilities offset,
in part, by a $5.9 million (21.7%) decline in sales to the New England Power
Pool.  Fluctuations in the level of wholesale electric sales have little, if
any, impact on earnings.

      For 1994, retail electric unit sales gained 1.4% as a result of
increased heating demand caused by the extremely cold weather conditions
during the first quarter and greater usage, particularly air conditioning
load, during the summer months.  Unit sales reflect continued moderate growth
of approximately 5,000 customers, mainly in the residential and commercial
sectors, resulting from more housing units and an improved economy that
produces added heating and air conditioning loads.  Growth in unit sales is
reduced somewhat by the system's conservation programs.  The system expects
that its retail unit sales growth will average 1% - 2% over the next five
years.

      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, a 1.9%
increase in retail unit sales and the recovery of approximately $2.4 million
in C&LM lost base revenues.  Partially offsetting these increases was a lower
level ($9 million) of C&LM program costs.  The decline in wholesale revenues
of $2.8 million (2.5%) was due to a 5.9% drop in unit sales to non-associated
utilities.

      Retail electric unit sales for 1993 increased by 1.9%, as each customer
segment improved, offset somewhat by the impact of conservation programs.  In
particular, unit sales reflected a moderate increase in customers, primarily
<PAGE>

residential and commercial, a greater demand for power from seasonal custom-
ers, reflecting an improved economy and to a lesser extent, more extreme
weather conditions.

      Fuel and Purchased Power

      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 entitlements pursuant to 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.

      The cost of fuel used for electric generation and purchased power per
KWH sold was $.043, $.042 and $.037 for 1994, 1993 and 1992, respectively. 
These costs constitute 56% in both 1994 and 1993 and 52% in 1992 of electric
operating revenues for the respective years and reflect the impact of the
system's contractual obligations to purchase higher-cost power.  These
contracts, negotiated in the 1980s when the system's customer base grew
dramatically and forecasts predicted continued growth, persisted to drive
costs up as additional "must run" capacity came on line displacing lower cost
units as the economy slowed.  In 1994, the system took aggressive action to
deal with the escalating energy costs by concluding the negotiation of a
restructured power sales agreement, effective January 1, 1995, with an
independent power producer (IPP) that defers purchases for a maximum of six
years and requires the facility to provide power on a dispatchable basis at
the discretion of Commonwealth Electric.  Another purchased power contract was
terminated through a buy-out arrangement effective January 27, 1995, pending
final Federal Energy Regulatory Commission (FERC) approval.  For further
details, refer to the "Power Contract Negotiations" discussion that follows.

      In 1994, the average cost reflects the moderating impact of the deferral
of $16 million of costs associated with Commonwealth Electric's rate
stabilization mechanism that was implemented on April 1, 1994 and is further
discussed in the "Rate Stabilization Plan" section to follow.  The cost per
KWH would have been $.045 in 1994 were this mechanism not in effect.

      For 1994 and 1993, fuel and purchased power costs increased $11 million
(3.2%) and $35.8 million (11.4%), respectively, due to higher unit sales in
both years and the contractual obligations discussed above prior to the
restructuring of one contract and the termination of a second.  In both years,
there were additional power purchases from certain natural gas-fired IPP
facilities and reduced generation from Canal Electric Company's units (for
sales to non-associate utilities).

      Fuel and purchased power in 1994 and 1993 includes the increased cost of
using cleaner burning but more expensive fuel oil (1% sulphur) at Canal
Electric.  In addition, 1993 expense includes $5.6 million for capacity-
related costs associated with certain purchased power contracts that were not
recovered in revenues due to the recovery mechanism established by the DPU. 
In 1994, this underrecovery was reduced to $800,000.  This underrecovery
reduced net income by $485,000 and $3.4 million in 1994 and 1993, respective-
ly.  (Refer to the "Cost Recovery" section of this discussion for more
information.)

      Energy Mix

      The system's energy mix, including purchased power, is shown below:

                                                 Actual            
                                     1994         1993        1992

      Natural gas.................    38%          29%         21%
      Nuclear.....................    25           26          27
      Oil.........................    24           31          41
      Waste-to-energy.............     9            8           7
      Hydro.......................     2            3           2
      Coal........................     2            3           2
        Total.....................   100%         100%        100%

      The system's energy mix has shifted during the last several years from
oil to natural gas and other fuels due to the requirement to purchase capacity
from IPP facilities and, to a lesser extent, continued efforts to reduce its
reliance on oil.  There were no new sources of system generation or purchased
power in 1994.  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 April 1997 to exchange 50 MW of Canal Electric's oil-
fired generation with 50 MW of pumped storage energy capacity from non-
affiliate New England Power Company's Bear Swamp Units (an initial, smaller
exchange of 25 MW began in 1992).  In 1991, Canal Electric arranged for a
long-term exchange of power with Central Vermont Public Service Company (CVPS)
whereby 50 MW from Canal Electric'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
and the purchaser.  The Canal Electric/Bear Swamp transaction alone will save
the system's customers $2.7 million over a four-year period that began in June
1993.  In 1995, it is expected that these exchanges, combined with a reduction
in the capacity from purchased power contracts with natural gas-fired IPPs,
will necessitate increased purchases from the oil-fired Canal Electric units.

      In October 1993, the system reached an agreement (subject to regulatory
approvals) 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.  Unit 2 will be modified to burn
gas as well as oil.  (Refer to "Environmental Matters" section for more
information.)

      Oil-fired generation has been significantly reduced from pre-1993 levels
but still accounts for 24% of the system's total sources, with higher levels
anticipated for 1995 and beyond.  Average oil prices in 1994 at Canal Elec-
tric's generating plant, a major supplier of electricity for the system, were
$14.33 per barrel as compared to $14.02 and $12.95 per barrel in 1993 and
1992, respectively.  In conformance with tighter restrictions on stack
emissions, the Massachusetts Department of Environmental Protection (DEP)
mandated a reduction in sulphur dioxide emissions requiring the periodic use
of lower-sulphur (1%) content oil.  In 1994, 1% oil averaged $14.92 per
barrel, a 1.6% and 12.1% decrease from the $15.16 and $17.25 per barrel cost
in 1993 and 1992, respectively.  However, in 1994 and 1993 lower-sulphur oil
displaced 70.4% and 57.5% of the higher-sulphur (2.2%) content oil as compared
to 24% in 1992.

      In addition to power purchases, the system is actively pursuing the
marketing of certain capacity at competitive terms and rates to utilities in
and outside the New England region at a higher price (thus saving the system's
customers the difference) than if it were to sell to the New England Power
Pool.  This situation is a result of several utilities in New England (the
<PAGE>
<PAGE 24>


system included) having excess capacity and lowered prospects for sales
growth.  This competitive business developed for the system in the early 1990s
when it began to formally request proposals to supply short-term energy and
associated capacity to other utilities on the open market to fulfill their
power requirements.  Increased emphasis on the marketing of this capacity
yielded approximate savings of $1,039,000, $429,000 and $451,000 in 1994, 1993
and 1992, respectively.

      For 1994, gas operating revenues increased $20.9 million (6.9%) due
primarily to an increase in the cost of gas sold of $20.4 million (13%),
higher C&LM costs ($2.6 million) that are recovered through a Conservation
Charge (CC) recovery mechanism which is part of the existing Cost of Gas
Adjustment Clause (CGAC), an increase in transportation revenues ($997,000)
and higher interruptible sales.  To the extent that costs associated with C&LM
programs increase or decrease from period to period, a corresponding change
will occur in revenues.  Included in other revenues for the first time were
new off-system sales.  The margin on these sales will be shared with one-half
used to reduce the cost of gas to firm customers and the remainder deferred
pending DPU approval of Commonwealth Gas Company's margin sharing proposal
that is expected to be filed in 1995.  Although the per unit cost of gas sold
decreased slightly, the increase in the total cost of gas sold reflects a 15%
increase in the volume of gas purchased due primarily to the off-system sales
noted above (there were no sales of this type in 1993) and sales from a new
"quasi-firm" service available to certain customers.  Quasi-firm sales service
is designed for larger customers and provides a combination of firm and
interruptible service.  In exchange for prices lower than full firm service,
quasi-firm customers will receive interruptible service in peak demand months
and firm service in off-peak months.

      Gas operating revenues for 1993 rose $7.8 million (2.6%) due primarily
to increases in C&LM costs ($4.8 million), the cost of gas sold ($2.4 million)
and an increase in transportation revenues ($479,000).  Offsetting these
increases were slightly lower unit sales.

      Firm sales gains from extreme cold weather experienced during the first
quarter of 1994 (5.6%) were substantially offset by the decline in fourth
quarter sales (15%) due to mild weather.  During January 1994, on four
different occasions, the system established all-time highs for daily send-out,
setting a new peak on January 19 of 364,799 MMBTU.  The previous all-time peak
was 336,998 MMBTU set in January 1988.  In 1993, firm gas sales declined by
1.5%, including a 7.2% decline in sales to industrial and other 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 no impact on net income since all of the margin
from these sales are flowed back to firm customers through the CGAC.  The
variations from year to year in weather conditions, particularly during the
heating season, cause gas usage to fluctuate.  The system expects that its
firm unit sales growth will average 1% - 2% over the next five years.

      The total number of customers remained stable in 1994 but increased at a
rate of 1.8% in 1993 due to new home construction and conversion activity. 
The fluctuation in interruptible sales during the three-year period reflects
the competitive market conditions for energy resources and the conversion in
1994 of interruptible sales to quasi-firm.

      The cost of gas sold per MMBTU averaged $3.74, $3.81 and $3.65 in the
years 1994, 1993 and 1992, respectively.  The average per unit cost in 1994
and 1993 reflects the amortization of FERC Order No. 636 (Order 636)
transition costs of $3.6 million and $396,000, respectively.  Pursuant to a
DPU order issued on October 29, 1993, transition charges related to Order 636
costs are reflected as a regulatory asset which Commonwealth Gas will recover,
with carrying charges, over a four-year period that began in November 1993, as
further discussed in the "Cost Recovery" section that follows.

      Other Operation and Maintenance

      In 1994, other operation was virtually unchanged due to the savings
resulting from the second quarter 1993 work force reduction ($2.7 million),
the absence of severance pay incurred in 1993 ($3.7 million) and a decline in
the provision for bad debt expense due to improved collection experience
($600,000).  The impact of these factors was offset by higher levels of
insurance and employee benefit costs ($2.4 million), a $1 million increase in
C&LM costs and the impact of inflation on the cost of labor, materials and
other services.

      Other operation in 1993 decreased $16.6 million (7.4%) due to lower C&LM
costs ($4.2 million), the absence in 1993 of costs associated with Common-
wealth 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 debt expense which
declined $2.7 million (22.8%) due to improved collection experience, lower
liability insurance costs of $1.7 million due to lower claims, lower Seabrook
operating costs of $1.1 million and a decline in employee medical and life
insurance costs of $800,000.  Offsetting these decreases, in part, was an
increase in pension costs of $1.5 million.

      Cambridge Electric, Commonwealth Electric and Commonwealth Gas have
received approval from the DPU to recover certain costs associated with C&LM
programs through the operation of a CC decimal.  For the years ended December
31, 1994, 1993 and 1992, C&LM costs (including amortization of prior period
<PAGE>

amounts), which are included in other operation expense in the accompanying
consolidated statements of income, were as follows:

                                        1994         1993         1992  
                                             (Dollars in Thousands)

      Cambridge Electric............   $ 1,227      $ 2,905      $ 4,246
      Commonwealth Electric.........     4,302        4,165       11,826
      Commonwealth Gas..............     7,685        5,094          286
         Total......................   $13,214      $12,164      $16,358

      Maintenance in 1994 declined $4.1 million (10%) due primarily to the
timing of scheduled maintenance at the Canal Units.  Maintenance in 1993
increased by $700,000 (1.9%) due primarily to a scheduled major inspection and
overhaul of the Canal Unit 2 boiler, turbine and generator.

      The total number of full-time employees declined 13.6% to 2,169 in 1994
from 2,510 employees at year-end 1991.  Management believes the work force
level is adequate to service its customers.

      Depreciation, Amortization and Taxes

      Depreciation expense in 1994 increased $1.7 million (4%) due to slightly
higher rates and higher levels of plant in service and the absence of an
adjustment made in 1993 which lowered that year's expense by approximately
$700,000 (1.6%) due to an adjustment to the accrual rate used by Canal
Electric to reflect an extension of the depreciable life of Unit 1 from 1996
to 2002.  The abandonment of the Cannon Street generating station also
contributed to the decrease in 1993.

      Amortization increased by less than 2% in 1994, while the decline in
this expense for 1993 of $1.7 million (21.9%) was due to the absence of
amortization costs related to Commonwealth Gas' automated mapping system.

      Income tax expense increased $900,000 (3.2%) in 1994 due to a higher
level of pretax income.  In 1993, income tax expense rose $7.7 million (37.5%)
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.

      Local property taxes increased $1.1 million (6.8%) in 1994 reflecting
higher tax rates and assessments.  The 2.7% increase in local property taxes
in 1993 primarily reflects higher tax rates and assessments offset, in part,
by an adjustment to the 1993 property tax accrual associated with revisions
made to the nuclear station property tax assessed by the state of New
Hampshire to the joint-owners of Seabrook 1.  Payroll and other taxes in 1994
declined nearly $600,000 (6.8%) reflecting the lower number of employees in
the current period.  The 3.8% increase in payroll and other taxes in 1993 was
due to an increase in unemployment tax rates.

      Other Income

      The substantial decrease in other income during 1994 was primarily due
to the absence of a 1993 second quarter reversal of a reserve ($3.8 million
pretax) related to Canal Electric's Seabrook 1 investment.  The decision to
eliminate this reserve was prompted by the inclusion of Seabrook 1 costs in
base rates at the state level for Cambridge Electric.  Another factor
contributing to the decrease was a $2 million (pretax) charge related to a
settlement negotiated with an outside party for certain costs associated with
Commonwealth Electric's energy conservation program.  The decline for 1994 was
offset, somewhat, by accrued interest on Commonwealth Electric's fuel charge
stabilization deferral ($674,000) and the equity component of allowance for
funds used during construction (AFUDC) of $341,000.  There was no equity AFUDC
in 1993.
<PAGE>
<PAGE 27>


      The substantial increase in other income during 1993 reflects the
reversal of the aforementioned reserve, offset, in part, by the absence in
1993 of equity AFUDC.

      Interest Charges

      For 1994, long-term interest charges increased $2 million (5.4%) due to
a higher level of long-term debt reflecting a full year of new debt issued at
various times in 1993 by Commonwealth Electric, Commonwealth Gas and Hopkinton
LNG Corp. ($134 million).  Interest on short-term borrowings declined by $2.3
million (33.5%) despite higher average interest rates (4.4% versus 3.5%) due
to the significantly lower average level of borrowings ($23.9 million versus
$103.1 million) resulting from a higher level of internally generated funds
and the 1993 financing activity.

      Interest charges increased in 1993 by $2.5 million (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 debt in the first quarter of 1993.  Somewhat
offsetting these increases was a $300,000 decline in other interest charges
due to lower rates (3.5% versus 4%) and a lower average level of short-term
borrowings ($103.1 million versus $126.3 million).

Liquidity and Capital Resources

      Overview

      The System is the largest combination public utility holding company in
New England with annual revenues approaching $1 billion and assets of approxi-
mately $1.3 billion.  Capital resources of the System and its subsidiaries are
derived principally from retained earnings and equity funds provided through
the System's Dividend Reinvestment and Common Share Purchase Plan (DRP). 
During 1994, nearly 34% of the System's shareholders participated in DRP. 
Supplemental 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 subsidi-
aries have over the years, maintained adequate financial resources and access
to the capital markets and further, do not anticipate a change in 1995 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.  These combined resources provide the funds required for the
subsidiary companies' construction programs, current operations, debt service
and other capital requirements.  In March 1994, the System's Board of Trustees
voted to increase the quarterly dividend per common share from 73 cents to 75
cents (2.7%) based on the System's improving financial condition and to
provide shareholders a fair and reasonable return.  Through February 1995, the
System has paid dividends without interruption or reduction since 1947 (191
consecutive quarters).

      Financial Condition

      For 1994, cash flows from operating activities amounted to approximately
$126.6 million including net income of nearly $49 million and non-cash items
such as depreciation ($44.2 million), amortization ($9.5 million) and deferred
income taxes of $14.8 million.  The change in working capital since December
31, 1993, exclusive of the changes in cash ($1.7 million) and interim
financing ($27.1 million), amounted to $52.7 million and had a significant
positive effect on cash flows from operating activities.  The working capital
change reflects lower levels of unbilled revenues ($10.1 million) and accounts
receivable ($1.5 million) coupled with higher levels of accounts payable
($27.9 million), accrued taxes ($8.9 million) and other miscellaneous current
assets and liabilities ($4.3 million).  The change in other operating items of
$41.8 million includes $16 million related to Commonwealth Electric's rate
stabilization deferral, $8.5 million related to uncollected postretirement
benefit costs, $2.6 million in uncollected Order 636 transition costs and
$14.7 million in other deferred costs.

      Capital Requirements

      Construction expenditures for 1994 were $58.6 million, including AFUDC
and nuclear fuel while sinking fund requirements and redemptions of long-term
debt amounted to $16.4 million for a total capital requirement of $75 million,
a decrease of $23.6 million from the 1993 level.  These requirements for 1994
were funded entirely with internally generated funds.  In addition, short-term
borrowings were reduced by $27.1 million to $44.9 million, which for the most
part, was funded with internal cash generated from higher retail electric unit
sales and continued cost containment efforts.

      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.  As conditions warrant, the system
will refinance certain of its outstanding securities based on acceptable
market conditions resulting in a lower cost of debt.  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 1995 through 1999 are as follows:

                                         1995  1996  1997  1998  1999  Total

       term debt and preferred shares.      6     9     9     8     8    40
         Total........................   $119  $119  $ 85  $ 93  $ 92  $508

      Sources of Capital

      It is anticipated that approximately $371 million or 73% of the
projected capital requirements shown 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 the sale of Common Shares through DRP, periodic
short-term borrowings from banks, rental income and dividends from
investments.

      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     1998     1999    Total
                                                (Dollars in Millions)

      Long-term debt......................  $ 62     $ 48     $ 41     $151
      Common stock........................    20       28       17       65
         Total............................  $ 82     $ 76     $ 58     $216

      The System could also raise 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 prim-
ary source of funds.  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.  In 1994, the subsidiaries of the system provided
$49.7 million to the Parent, and proceeds from DRP provided $9.4 million.  In
1993, these amounts were $64.3 million and $7.1 million, respectively.

      System companies also maintain lines of credit with banks.  At December
31, 1994, short-term notes payable to banks were $44.9 million, representing
the lowest year-end level since 1986 and a decrease of $27.1 million (38%)
<PAGE>
<PAGE 29>


from last year.  Bank borrowings are used to temporarily fund construction
projects and to repay the long-term debt of the System and its subsidiary
companies ($10 million in 1994).  Arrangements for bank lines of credit
totaled $90 million in committed lines and $90 million in uncommitted lines at
December 31, 1994, at which time approximately $135 million was available to
the system.  At December 31, 1999, the system's level of bank borrowings is
projected to be approximately $1.8 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
short-term debt.  The system's capitalization structure, including short-term
debt, is presented below:
                                                                  Estimate

      Total capitalization $883,418 100.0%   $865,814 100.0%   $955,214 100.0%

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.

      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 were as follows:

                                                            Return on

      Cost Recovery

         Fuel and Purchased Power

      Commonwealth Electric and Cambridge Electric file Fuel Charge (FC) rate
schedules, subject to DPU regulation, under which they are allowed current
recovery from retail customers of costs of fuel used in electric generation
and a substantial portion of purchased power, demand and transmission costs.
<PAGE>
<PAGE 30>


      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 dollar-for-dollar through the FC.  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, the companies were encouraged by the
DPU's acknowledgement that the issues presented warranted further considera-
tion.  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 future consideration.  The companies
have been involved in discussions with interested parties in an effort to
resolve this issue in a positive fashion and hope to reach an agreement in the
near future.

         Cost of Gas Sold

      Commonwealth Gas has a standard seasonal Cost of Gas Adjustment Clause
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 and other non-firm
sales.  Actual gas costs are reconciled annually as of October 31, and any
difference is included as an adjustment in the following year.

         C&LM Programs

      The system has implemented a variety of cost-effective C&LM programs for
its gas and electric customers 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 employed by the DPU to encourage effective implementa-
tion 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.  Commonwealth Electric and Cambridge Electric recovered
approximately $3.6 million based on estimated KWH savings for the eighteen-
month period that began January 1, 1993.  Customer collections began July 1,
1993 over a twelve-month period.  On June 30, 1994, the DPU issued an order
that further allows the companies to recover approximately $3.8 million in
additional lost base revenues for a one-year period that commenced July 1,
1994.  Through December 31, 1994, the combined recovery was approximately $5.7
million, $2.4 million of which was collected in 1993.

      Commonwealth Gas offers conservation measures and energy savings to its
residential and multi-family customers through programs approved by the DPU in
June 1992 and is recovering costs via separately stated CC decimals approved
in that year.  On November 23, 1994, the DPU approved a settlement agreement
extending Commonwealth Gas' existing demand-side management (DSM) programs
until October 31, 1995 and allowing the recovery of "lost margins" from its
customers that commenced in January 1995.  Specifically, the settlement allows
Commonwealth Gas to recover through the CC decimal the portion of the lost
margins related solely to savings resulting from installations during the
twelve-month period which began in November 1994.  In addition, the lost
margins related to savings occurring from prior period installations will be
held in an interest-bearing account pending the completion of a DSM impact
evaluation proceeding currently before the DPU.

         FERC Order No. 636

      In April 1992, the FERC issued Order No. 636 (Order 636), which became
effective on November 1, 1993.  The order requires interstate pipelines to
unbundle existing gas sales contracts into separate components (gas sales,
transportation and storage services).  Order 636 requires pipelines to provide
transportation services that allow customers to receive the same level and
quality of service they had with the previous bundled contracts.  Prior to the
implementation of Order 636, Commonwealth Gas purchased the majority of its
gas supplies from either Tennessee Gas Pipeline Company or Algonquin Gas
Transmission Company, supplemented with third-party firm gas purchases,
storage services, and firm transportation from various pipelines.  Presently,
Commonwealth Gas purchases only transportation, storage and balancing services
from these pipelines (and other upstream pipelines that bring gas from the
supply wells to the final transporting pipelines) and  purchases all of its
gas supplies from third-party vendors, utilizing firm contracts with terms
ranging from less than one year to three or more years.  The vendors vary from
small independent marketers to major gas and oil companies.  (Refer to Note
2(g) of the accompanying Notes to Consolidated Financial Statements for more
information.)

         Potential Impact of Regulatory Restructuring

      Based on the current regulatory framework in which it operates, the
system accounts for the economic effects of regulation in accordance with the
provisions of Statement of Financial Accounting Standards (SFAS) No. 71,
"Accounting for the Effects of Certain Types of Regulation."  Under SFAS No.
71, a utility is allowed to defer costs that would otherwise be expensed in
recognition of the ability to recover them in future rates.  As a result, the
system has accumulated $111.7 million of regulatory assets (approximately 8%
of total assets) as of December 31, 1994.  Management believes that the
current regulatory framework provides for the continued recovery of these
assets.

      In the event that recovery of specific costs through rates becomes
uncertain or unlikely in the future either as a result of the expanding
effects of competition or specific regulatory actions, the system could be
required to move away from cost-of-service ratemaking and, therefore, SFAS
No.71 would no longer apply.  Discontinuation of SFAS No. 71 could lead to the
write-off of various regulatory assets, which would have an adverse impact on
the system's financial position and results of operations.  At this time,
management believes that it is unlikely that regulatory action would lead to
the discontinuation of SFAS No. 71 in the near future.

Competition

      This past year, the system continued to develop and implement strategies
to deal with the increasingly competitive environment in our gas and electric
businesses.  The inherently high cost of providing energy services in the
Northeast has placed the region at a competitive disadvantage as more
customers begin to explore alternative supply options.  Many state and federal
government agencies are considering implementing programs under which utility
and non-utility generators can sell electricity to customers of other
utilities without regard to previously closed franchise service areas.  In
1994, the DPU began an inquiry into incentive ratemaking and in February 1995
opened an investigation into electric industry restructuring.

      System company actions in response to the new competitive challenges
have been well received by regulators, business groups and customers. 
Commonwealth Gas and Commonwealth Electric have developed and continue to
develop innovative pricing mechanisms designed to retain existing customers,
add new retail and wholesale customers and expand beyond current markets.

      Commonwealth Electric recently revised its Economic Development Rate
which will benefit a number of high-use industrial customers and contribute to
<PAGE>

economic development in the area.  Another new rate will provide incentive for
business to expand into previously vacant space and its Rate Stabilization
Plan, approved in 1994, continues to hold the line on costs passed on to
customers while aggressively pursuing other cost reduction measures.  Recently
completed contract negotiations are expected to save customers approximately
$42 million through 1999 as we continue to explore opportunities to reduce
purchased power costs.  Commonwealth Electric recently signed an agreement
with another New England utility to purchase peaking-unit capacity at rates
lower than that available from the New England Power Pool or other regional
utilities.

       FERC Order 636 (November 1993) marked the beginning of the deregulation
and restructuring of the natural gas industry.  In addition to opening up
customer markets to competition, the regulations shifted many supply-related
responsibilities to local distribution companies including direct gas
purchases from suppliers, pipelines and producers, transportation services and
storage services.  Commonwealth Gas has developed a gas control and informa-
tion system that is one of the most sophisticated purchasing and tracking
systems in the industry.  This ability, coupled with aggressive planning and
procurement strategies will help to secure Commonwealth Gas' existing market
and permit the expansion of core and non-core supply capabilities.

       Commonwealth Gas' substantial LNG and storage capabilities provide it
with the reliability needed during the coldest winter days and the flexibility
to sell capacity when supply and pricing conditions are favorable.  Twenty
percent of the gas purchased during 1994 was sold outside Commonwealth Gas'
franchise area.  These off-system sales reduced average gas costs by four
cents per MMBTU or a total of $1.7 million.  These developments are pushing
the gas business beyond traditional markets and Commonwealth Gas  will begin
to profit from these actions, pending DPU approval, by sharing in the margins
produced in the new competitive arena.

      System companies continue to be aggressive in their cost containment
efforts.  For example, through work force reductions and attrition the system
has reduced its work force approximately 16.3% since 1989.  Also, the intro-
duction of advanced technologies in the workplace continues to improve
customer service and our competitive position in our businesses.  The system
has yet to be significantly impacted by the increase in competition, and
absent a major shift in regulation at the state level, believes its current
strategy will have a positive impact in the near-term.

      Some of the more specific details of the innovative measures taken in
response to competition include the following:

      Rate Stabilization Plan

      Commonwealth Electric implemented a FC rate settlement on April 1, 1994
that stabilizes its quarterly FC rate during the years 1994 through 1996 at
6.5 cents per KWH and no greater than 6.7 cents per KWH during 1997.  The
settlement results in billings at a lower rate than would have otherwise been
in effect and could save customers between 1.75% and 5% on their annual elec-
tric bills through 1997.  This rate stabilization is achieved through the use
of a cost deferral mechanism that was sponsored jointly by Commonwealth
Electric and the Massachusetts Attorney General and approved by the DPU.  The
deferred costs are reflected as a regulatory asset to be recovered, with
carrying charges, over the subsequent six-year period beginning in 1998
pursuant to a recovery schedule yet to be determined and subject to DPU
approval.  The deferred amount, excluding carrying charges, is restricted to a
maximum of $40 million during the settlement period (1994 through 1997) and is
further limited to an annual amount of $16 million.  Commonwealth Electric
deferred $15,964,000 in 1994.  In view of recent contract renegotiations, the
system does not expect deferred amounts to exceed $20 million through 1997.

      The rate stabilization mechanism is part of a long-term plan to control
Commonwealth Electric's retail rates.  This plan will help eliminate the
<PAGE>
<PAGE 33>


disincentive for economic development resulting from a volatile and unpredict-
able FC rate.  The stabilized FC rate will enable current and prospective
customers to better plan their business and personal finances in a more
efficient and effective manner.  In addition to the Massachusetts Attorney
General, this proposal has been widely supported by various business and
customer groups and other political interests.

      Power Contract Negotiations

      Commonwealth Electric concluded the negotiation of a restructured Power
Sale Agreement (PSA), effective January 1, 1995, with Lowell Cogeneration
Company Limited Partnership (23 MW).  The restructured PSA will allow the
system to defer the purchase of capacity and energy for a maximum of six years
and allows the purchase of power from the plant, when called back into
service, to be dispatched only when needed at the discretion of Commonwealth
Electric.  In addition, Commonwealth Electric terminated a PSA with Pepperell
Power Associates Limited Partnership (38 MW), effective January 27, 1995,
through a buy-out arrangement that is subject to final FERC approval.  In
1994, the power purchased from these units cost the system 6 cents per
kilowatthour as compared to costs at the system's Canal Electric units of 3.5
cents.  It is expected that the resolution of these contracts will enhance
Commonwealth Electric's competitiveness by lowering costs and saving customers
approximately $42 million through 1999.

      Economic Development

      Realizing a healthy regional economy benefits not only businesses but
all area residents, Commonwealth Electric actively encourages economic growth
by working in partnership with communities and businesses, providing resources
and incentives to drive the region's economy.  One initiative involves funding
the development of an action plan to guide the work of the Massachusetts
Textile and Apparel Council, a trade group organized to improve competitive-
ness and job creation throughout the industry.  Commonwealth Electric also
funded the development of a business plan that focuses on improving
infrastructure, regulation, access to capital, marketing and promotion,
cooperation and leadership on Cape Cod.

      In an effort to foster industrial development in its service area,
Commonwealth Electric began offering an Economic Development Rate (EDR) in
October 1991 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, 1994, twenty-three commercial and industrial
customers were 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.  Revenues were lower by $1.7 million, $1.5 million and $1.3 million
in 1994, 1993 and 1992, respectively.  These amounts represent the difference
between what certain commercial and industrial customers would have paid prior
to the availability of this rate.  Commonwealth Electric also received
approval for a Vacant Space Rate that is available to qualifying small
commercial and industrial customers who establish loads in previously
unoccupied building space.

      Quasi-firm and Off-system Gas Sales Services

      In late August 1994, Commonwealth Gas received regulatory approval for a
new quasi-firm sales service that is designed for larger customers and
provides a combination of firm and interruptible service.  In exchange for
prices lower than full firm service, quasi-firm customers will receive
interruptible service in peak demand months and firm service in off-peak
months.  These arrangements will give Commonwealth Gas and its customers more
flexibility in a constantly changing environment.
<PAGE>
<PAGE 34>


      During 1994, Commonwealth Gas was able to maximize the use of its gas
supply resources through off-system sales.  These efforts primarily help to
reduce the cost of gas to Commonwealth Gas' firm customers thereby serving to
make Commonwealth Gas more competitive in its traditional markets.

Environmental Matters

      Commonwealth Gas is participating in the assessment of a number of
former manufactured gas plant (MGP) sites and alleged MGP waste disposal
locations to determine if and to what extent such sites have been contaminated
and whether Commonwealth Gas may be responsible for remedial actions.

      The costs associated with the assessment and clean-up of these sites are
recoverable in rates through the cost of gas adjustment clause over a seven-
year amortization period without carrying costs pursuant to a 1990 DPU order. 
Commonwealth Gas has recorded an estimated $2.3 million liability that
reflects its best estimate (based on current information) of the costs to be
incurred in connection with the assessment and remediation activities
identified to this point.  Commonwealth Gas has also recorded a regulatory
asset in anticipation of recovery of these costs.  Commonwealth Gas is unable
to predict the total cost to ultimately resolve these matters, due to
significant uncertainty as to the actual site conditions and the extent of any
associated remediation activities and the assignment of responsibility. 
However, it is expected that all such costs will continue to be recovered in
rates as described above.

      Commonwealth Gas and certain other system subsidiaries are also involved
in other known or potentially contaminated sites where the associated costs
may not be recoverable in rates and have recorded an estimated liability (and
a charge to operations) of $760,000 to cover the expected costs associated
with assessment and remediation activities.  These estimates are reviewed and
adjusted periodically as further investigation and assignment of responsibil-
ity occurs.  The system is unable to estimate its ultimate liability for
future environmental remediation costs.  However, in view of the system's
current assessment of its environmental responsibilities, existing legal
requirements and regulatory policies, management does not believe that these
matters will have a material adverse effect on the system's results of
operations or financial position.

      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 DEP 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.  

Power Contract Arbitrations

      On May 2, 1994, Commonwealth Electric and Cambridge Electric gave notice
of termination of power purchase agreements with Eastern Energy Corporation,
the developer of a proposed 300 MW coal-fired plant, based upon the
developer's failure to meet its contractual obligations.  In June 1989,
Commonwealth Electric and Cambridge Electric agreed to buy 27% (50 MW and 33
MW, respectively) of the power to be produced by the proposed plant, original-
ly scheduled to begin operation in January 1992.  The developer did not meet
the permitting, construction or operation milestones established by the
contracts, and has not yet obtained the required permits, commenced construc-
tion or sold any additional power from the proposed plant.  Efforts to reshape
the power purchase agreements to provide a satisfactory arrangement were
unsuccessful.  In a letter dated June 30, 1994, the developer objected to the
notices of termination and invoked arbitration, which is pending.  A decision
by the arbitrators on the legality of Commonwealth Electric's and Cambridge
Electric's termination is expected in 1995.
<PAGE>
<PAGE 35>


      Commonwealth Electric has initiated an arbitration proceeding with
Dartmouth Power Associates, an IPP, seeking approximately $5 million for
recovery of excess fuel charges billed to Commonwealth Electric for power
purchases in 1992.  A decision is expected from the arbitrators in 1995.

                   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, 1994 and
1993, and the related consolidated statements of income, cash flows, changes
in common shareholders' investment and changes in redeemable preferred shares
for each of the three years in the period ended December 31, 1994.  These
financial statements are the responsibility of the System and subsidiary
companies' management.  Our responsibility is to express an opinion on these
consolidated 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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of the System
and subsidiary companies as of December 31, 1994 and 1993, and the results of
their operations and their cash flows for each of the three years in the
period ended December 31, 1994, 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.  Similarly, certain regula-
tory liabilities established by the system are required to be refunded to
customers over time.  The principal regulatory assets included in deferred
charges at December 31, 1994 and 1993 were as follows:

                                                         1994        1993
                                                      (Dollars in Thousands)

      Postretirement benefit costs including
        pensions                                      $ 20,129     $ 11,593

      Regulatory assets as a percent of total assets       8.3%         7.0%

      The principal regulatory liabilities, reflected in deferred credits-
other and relating to income taxes, were $17.3 million and $17.9 million at
December 31, 1994 and 1993, respectively.

      (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.

                          COMMONWEALTH ENERGY SYSTEM

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

      (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 and
environmental 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 $306,000 in 1994 and $5,565,000 in 1993, is
recorded as unbilled revenues.  Commonwealth Electric also has implemented a
Fuel Charge (FC) rate settlement that stabilizes its quarterly FC rate for the
years 1994 through 1997 by utilizing a cost deferral mechanism approved by the
DPU.  The deferral, which will ultimately be recovered in revenues beginning
in 1998, is limited to $16 million annually (excluding carrying charges) and
is further restricted to a maximum of $40 million during the settlement
period.

      (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: 

                                     1994    1993    1992

      Electric                       3.30%   3.28%   3.49%
      Gas                            2.98    2.95    2.90
      Steam                          3.94    3.61    3.50
      LNG                            3.12    3.07    3.00

      (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
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 9.1% in 1994,
3.9% in 1993 and 4.5% in 1992.

(2) Commitments and Contingencies

      (a)  Construction

      The system is engaged in a continuous construction program presently
estimated at $357.4 million for the five-year period 1995 through 1999.  Of
that amount, $87.7 million is estimated for 1995.  The program is subject to
periodic review and revision.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

      (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:

      Canal and the other joint owners have established a Seabrook Nuclear
Decommissioning Financing Fund to cover post operation decommissioning costs. 
For the years 1994, 1993 and 1992, Canal paid $271,000, $259,000 and $235,000,
respectively, as its share of the cost of this fund.  The estimated cost to
decommission the plant is $382 million in 1994 dollars, through December 31,
1994.  Canal's share of this liability (approximately $13.4 million) less its
share of the market value of the decommissioning trust ($1 million) is
approximately $12.4 million.

      (c) Price-Anderson Act

      Under the Price-Anderson Act (the Act), owners of nuclear power plants
have the benefit of approximately $9 billion of public liability coverage
which would compensate the public for valid bodily injury and property loss on
a no fault basis in the event of an accident at a commercial nuclear power
plant.  Under the provisions of the Act, each nuclear reactor with an
operating license can be assessed up to $79.2 million per nuclear incident
with a maximum assessment of $10 million per incident within one calendar
year.  Nuclear plant owners have initiated insurance programs designed to help
cover liability claims relating to property damage, decontamination,
replacement power and business interruption costs for participating utilities
arising from a nuclear incident.

      The system has an equity ownership interest in four nuclear generating
facilities as well as a 3.52% joint-ownership interest in Seabrook 1.  The
operators of these units maintain nuclear insurance coverage (on behalf of the
owners of the facilities) with Nuclear Electric Insurance Limited (NEIL II and
NEIL III) and the combined American Nuclear Insurers/Mutual Atomic Energy
Liability Underwriters (ANI).  NEIL II provides $1.4 billion of property,
<PAGE>
<PAGE 46>


                          COMMONWEALTH ENERGY SYSTEM

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

boiler, machinery and decontamination insurance coverage, including $250
million of accidental premature decommissioning losses both in excess of the
$500 million required by the Act.  NEIL III provides $850 million of
additional insurance coverage.  All companies insured with NEIL are subject to
retroactive assessments if losses exceed the accumulated funds available.  ANI
provides $500 million of "all risk" property damage, boiler, machinery and
decontamination insurance.  An additional $200 million of primary financial
protection coverage is provided for off-site bodily injury or property damage
caused by a nuclear incident.  ANI also provides secondary financial
protection liability insurance which currently provides $8.7 billion of
retrospective insurance premium benefits in accordance with the provisions of
the Act.  Additional coverage provided by ANI includes tort liability
protection arising out of radiation injury claims by nuclear workers and
injury or property damage caused by the transportation or shipment of nuclear
materials or waste.

      Based on its various ownership interests in the five nuclear generating
facilities, the system's retrospective premium could be as high as $1.9
million yearly or a cumulative total of $15.1 million, exclusive of the effect
of inflation indexing (at five-year intervals) and a 5% surcharge ($4 million)
in the event that total public liability claims from a nuclear incident exceed
the funds available to pay such claims.

      (d)  Power Contracts

      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 in which the system has an equity ownership (Yankee
Nuclear Units) is as follows:

      Commonwealth Electric successfully negotiated a restructured Power Sale
Agreement (PSA), effective January 1, 1995, with an independent power producer
(IPP) that defers purchases for a maximum of six years and requires the
facility to provide power on a dispatchable basis at the discretion of
Commonwealth Electric.  In addition, Commonwealth Electric terminated a PSA
with another IPP, effective January 27, 1995, through a buy-out arrangement,
the cost of which will be recorded as a regulatory asset in 1995 pending final
FERC approval.

      (e)  Yankee Atomic Nuclear Power Plant

      In February 1992, the Board of Directors of Yankee Atomic Electric
Company (Yankee Atomic) agreed to permanently discontinue power operation and
decommission the Yankee Nuclear Power Station (the plant).  At December 31,
1994, Cambridge and Commonwealth Electric's respective 2% and 2.5% investment
in Yankee Atomic was approximately $1.2 million.  The companies' estimated
decommissioning costs include its unrecovered share of all costs associated
with the shutdown of the plant, recovery of its plant investment, and
decommissioning and closing the plant.  The most recent cost estimate to
permanently shut down the plant is approximately $408.2 million.  The
companies' share of this liability is $18.4 million and is currently reflected
in the accompanying consolidated balance sheets as a liability and
corresponding regulatory asset.  The market value of the companies' share of
assets in the plant's decommissioning fund at December 31, 1994 is
approximately $4.9 million.

      (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 on the System's operations in the past and will
continue to have an impact on 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

      As a result of implementing FERC Order No. 636 (Order 636), each
interstate pipeline company is allowed to collect certain transition costs
from its customers that resulted from the pipelines' need to buy out gas
supply contracts entered into prior to the issuance of Order 636. 
Commonwealth Gas has been billed a total of approximately $21.7 million from
Tennessee Gas Pipeline Company (Tennessee), Algonquin Gas Transmission Company
and Texas Eastern Transmission Company (Texas Eastern) through December 31,
1994.

      As of October 29, 1993, Commonwealth Gas received preliminary DPU
authorization to recover these costs, with carrying charges, through the cost
of gas adjustment (CGA) over a four-year period that began in November 1993. 
As a result, a regulatory asset totaling $19.2 million is reflected in
deferred charges as of December 31, 1994.  In addition, a related liability of
$7.8 million is reflected in deferred credits.  Final DPU approval for
recovery was received in March 1995.

      After extensive negotiations between Texas Eastern, Tennessee and their
customers (including Commonwealth Gas), settlements were reached regarding a
number of transition obligation issues.  The settlement with Texas Eastern,
which was approved by FERC, calls for the pipeline to absorb approximately 20%
of all transition costs incurred from June 1993 forward.  This agreement also
provides for an extended billing period and annual caps on the collection of
future costs.  Commonwealth Gas believes that the absorption requirement will
give the pipeline incentive to minimize future costs.  This settlement
resulted in a refund of $2.7 million to Commonwealth Gas which will be
refunded to firm customers beginning in 1995.

      The settlement with Tennessee, which received preliminary approval from
the FERC on November 15, 1994, pending rehearings, will lower one element of
Commonwealth Gas' transition obligation by approximately $1 million.  Further
negotiations are underway with Tennessee to craft a total settlement similar
to that achieved with Texas Eastern.

      Commonwealth Gas is continuing to negotiate with the pipelines on
several other issues.  As a result, Commonwealth Gas is unable to predict its
final transition obligation at this time; however, based on these and
subsequent settlement activities, Commonwealth Gas will adjust its regulatory
asset and liability accounts accordingly.

(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.

      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
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 1994 and
1993:

      The total income tax provision set forth on the previous page represents
37% in 1994, 38% in 1993 and 23% in 1992 of income before such taxes.  The
following table reconciles the statutory federal income tax rate to these
percentages:

      On April 22, 1992, the DPU approved a settlement agreement between
Commonwealth Electric, the Attorney General of Massachusetts and a consumer
group, which 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.

      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
ratemaking, 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:

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

      (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
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.

      In 1993, the system began making contributions to various voluntary
employees' beneficiary association (VEBA) trusts that were established
pursuant to section 501(c)9 of the Internal Revenue Code (the Code).  The
system also makes 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 $14.5 million and
$12.6 million to these trusts during 1994 and 1993, respectively.

      The net periodic postretirement benefit cost for the years ended
December 31, 1994 and 1993 include the following components and related

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

      The funded status of the system's postretirement benefit plan using a
measurement date of December 31, 1994 and 1993 is as follows:

                                                        1994        1993

      The following actuarial assumptions were used in determining the plan's
year-end funded status:

                                                        1994        1993

      Discount rate                                     8.50%       7.25%
      Rate of increase in future compensation           5.00        4.50

      In determining its estimated APBO and the funded status of the plan for
1994 and 1993, the system assumed estimated health care trend rates as
follows:

                                                        1994        1993

      Medicare part B premiums                         12.30%      14.90%
      Medical care                                      8.50        9.00
      Dental care                                       5.00        5.00

      The above rates, with the exception of the dental rate which remains
constant, decrease to five percent in the year 2007 and remain at that level
thereafter.  A one percent change in the medical trend rate would have a $1.6
million impact on the system's annual expense (interest component - $1.1
million; service cost - $500,000) and would change the transition obligation
by approximately $13.9 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
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
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 expense as a regulatory asset.  At December 31, 1994 and 1993,
this deferral amounted to approximately $15.7 million and $8.9 million,
respectively.

      (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 health benefits.  The total system contribution was $4,302,000
in 1994, $4,245,000 in 1993 and $4,134,000 in 1992. 

(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, 1994, system companies had $90 million
of committed lines of credit that will expire at varying intervals in 1995. 
These lines are normally renewed upon expiration and require annual fees of up
to .1875% of the individual line.  At December 31, 1994, the uncommitted lines
of credit totaled $90 million.  Interest rates on the outstanding borrowings
generally are at an adjusted money market rate and averaged 4.4% and 3.5% in
1994 and 1993, respectively.  Notes payable to banks totaled $44,850,000 and
$71,975,000 at December 31, 1994 and 1993, 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,
1994 are as follows:

                    Sinking Funds    Maturing Debt Issues

      1999               7,653        10,000     10,000       27,653

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

                                   Sinking Funds          Optional
                  Dividend           1995-1999           Redemption

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

      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)   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, 1994 and 1993 are
as follows:


                                  1994                  1993

    Long-term Debt         $449,280  $449,292     $464,866  $526,405
    Preferred Stock          15,480    14,687       16,300    15,759

      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
on 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.

      The following is a breakdown, by major class, of property under capital
lease at December 31, 1994 and 1993:

                                                     1994        1993

$13,149,000 in 1992.  There were no contingent rentals and no sublease rentals
for the years 1994, 1993 and 1992.

(9)   Dividend Restriction

      At December 31, 1994, approximately $114,876,000 of consolidated
retained earnings was restricted against the payment of cash dividends by
terms of indentures and note agreements securing long-term debt.

(10)  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.
