                             EMPLOYEES SAVINGS PLAN
             OF COMMONWEALTH ENERGY SYSTEM AND SUBSIDIARY COMPANIES

                    Report of Independent Public Accountants

To the Savings Plan Board of the Employees Savings Plan of Commonwealth Energy
System and Subsidiary Companies:

    We have audited the accompanying statements of net assets available for
benefits, with fund information, of the EMPLOYEES SAVINGS PLAN OF COMMONWEALTH
ENERGY SYSTEM AND SUBSIDIARY COMPANIES as of December 31, 1998 and 1997, and
the related statements of changes in net assets available for benefits, with
fund information, for each of the three years in the period ended December 31,
1998.  These financial statements and the supplemental schedules referred to
below are the responsibility of the plan administrator.  Our responsibility is
to express an opinion on these financial statements and supplemental schedules
based on our audits.

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

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the net assets available for benefits, with fund
information, of the Employees Savings Plan of Commonwealth Energy System and
Subsidiary Companies as of December 31, 1998 and 1997, and its changes in net
assets available for benefits, with fund information, for each of the three
years in the period ended December 31, 1998, in conformity with generally
accepted accounting principles.

    Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole.  Supplemental Schedules I and II are
presented for purposes of additional analysis and are not a required part of
the basic financial statements, but are supplemental information required by
the Department of Labor's Rules and Regulations for Reporting and Disclosure
under the Employee Retirement Income Security Act of 1974.  The Fund Informa-
tion in the statement of net assets available for benefits, with fund informa-
tion, and the statement of changes in net assets available for benefits, with
fund information, is presented for purposes of additional analysis rather than
to present the net assets available for benefits and changes in net assets
available for benefits of each fund.  The supplemental schedules and Fund
Information have been subjected to the auditing procedures applied in the
audits of the basic financial statements and, in our opinion, are fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

                             EMPLOYEES SAVINGS PLAN
             OF COMMONWEALTH ENERGY SYSTEM AND SUBSIDIARY COMPANIES

                          NOTES TO FINANCIAL STATEMENTS

(1) General Information

    The Employees Savings Plan of Commonwealth Energy System and Subsidiary
Companies (the Plan) was originally created in 1962 by Commonwealth Energy
System (COM/Energy) and its subsidiary companies to assist employees in
adopting a regular savings program and to help employees by providing addi-
tional security for their retirement.  The Plan has been amended or restated
from time to time thereafter.  The latest Plan amendments became effective
January 1, 1998 and relate to changes in eligibility requirements and allow-
ance of rollovers from other qualified plans or Individual Retirement Accounts
to the Plan.

    Vanguard Fiduciary Trust Company of Valley Forge, Pennsylvania, has acted
as Trustee for the Plan (Plan Trustee) since January 1, 1989.  The Trustee
retains the Plan assets and provides records of Plan activity to a Plan Agent
designated by a three-member Savings Plan Board (the Board) that is appointed
by the Trustees of COM/Energy and by the directors of its subsidiary compa-
nies.  The Board is responsible (except for the duties specifically vested in
the Plan Trustee) for the administration of the Plan.

    The term "Participant" as used in this report shall be deemed to include
Members, Inactive Members or Former Members, all as defined in the Plan.

    The Employers participating in the Plan consist of certain, wholly-owned
subsidiary companies of COM/Energy, as follows: Cambridge Electric Light
Company, Canal Electric Company, Commonwealth Gas Company, COM/Energy Services
Company, Commonwealth Electric Company, Advanced Energy Systems, Inc. (effec-
tive December 1996), COM/Energy Marketing, Inc. (effective May 1997) and
COM/Energy Technologies, Inc. (effective September 1997) (Employers).

    The electric utility industry has continued to change in response to
legislative and regulatory mandates that are aimed at lowering prices for
energy by creating a more competitive marketplace.  These pressures have
resulted in an increasing trend in the electric industry to seek competitive
advantages and other benefits through business combinations.  On December 5,
1998, COM/Energy and BEC Energy (BEC), headquartered in Boston, Massachusetts,
entered into an Agreement and Plan of Merger (the Merger Agreement).  Pursuant
to the Merger Agreement, COM/Energy and BEC will be merged into a new holding
company to be known as NSTAR.  The regulatory approval process is expected to
be completed during the second half of 1999.  Upon completion of the merger,
each Common Share of COM/Energy held by the Plan in the Commonwealth Energy
System Common Share Fund will be converted into 1.05 shares of NSTAR or $44.10
in cash (subject to certain restrictions) based on elections to be made by
Participants.

    On December 30, 1998, COM/Energy sold substantially all of its electric
generating facilities to affiliates of Southern Energy New England, L.L.C., an
affiliate of The Southern Company of Atlanta, Georgia (Buyer).  As a result of
this sale, approximately 150 Plan Participants transferred employment to the
Buyer.  The Buyer has advised the Board that it will not accept a trustee-to-
trustee transfer (within the meaning of Section 414(1) of the Internal Revenue
Code (IRC)) of all assets from the Plan attributable to these Participants,

                             EMPLOYEES SAVINGS PLAN
             OF COMMONWEALTH ENERGY SYSTEM AND SUBSIDIARY COMPANIES

                          NOTES TO FINANCIAL STATEMENTS

and thus, COM/Energy continues to maintain the accounts of these Participants.
The Plan intends to file with the Internal Revenue Service (IRS) in 1999 for a
private letter ruling on whether the Plan may distribute to these Participants
amounts attributable to their elective contributions as a result of the sale
without adversely affecting the qualified status of the Plan's cash or
deferred arrangement under Section 401(k) of the IRC and of the Plan under
section 401(a) of the IRC.

    Each eligible employee, upon joining the Plan, shall specify in one
percent (1%) increments his or her contributions and the applicable Employer
contributions to be invested in each of twelve separate Investment Funds
(Fund(s)) that are collectively referred to as the Trust Fund (Trust Fund). 
The Trust Fund is described in Note 4.

    Participants may change their Fund allocation contribution daily by
contacting Vanguard Participant Services.  However, not more than fifty
percent (50%) of a Participant's contributions and the applicable Employer
contributions may be allocated to the Commonwealth Energy System Common Share
Fund.

    The Plan is subject to provisions of the Employee Retirement Income
Security Act of 1974 (ERISA), the Retirement Equity Act of 1984, the Tax
Reform Act of 1986, the Omnibus Budget Reconciliation Act of 1993, and the
Taxpayer Relief Act of 1997 relating to plans of this type.

(2) Significant Accounting Policies

    (a) Principles of Accounting

    The financial statements of the Plan are prepared under the accrual method
of accounting.  Shares in Funds of the Plan Trustee are valued at quoted
market prices that represent the net asset value of shares held by the Plan at
year-end.  The Commonwealth Energy System Common Share Fund is valued at its
year-end closing market price and may include uninvested cash.  Participant
loans are valued at cost which approximates fair value.  In addition, certain
prior period amounts are reclassified from time to time to conform with the
presentation used in the current year's financial statements.

    (b) Federal Income Taxes

    The Plan is subject to certain provisions of the IRC and qualifies under
Section 401(a) and 401(k) of the IRC.  The IRS has issued a favorable determi-
nation letter, applicable to Plan years beginning after January 1, 1993 and
for amendments adopted on January 15, 1993, which indicates that the Plan was
designed in accordance with applicable IRC requirements.  The Board believes
that the Plan, as amended, is currently designed and operated in accordance
with applicable IRC requirements.  As a result, the Plan has not provided for
Federal income taxes.  Generally, Participants are not subject to taxes on
contributions or the earned income until such time as distributions are made.

                          NOTES TO FINANCIAL STATEMENTS

    (c) Expenses

    Brokerage fees, commissions, stock transfer taxes and other expenses in
connection with the purchase, sale or distribution of securities for each Fund
may be charged to such Fund.  Any expense of litigation may be paid by the
Plan Trustee and charged to the Trust Fund or to the Fund or Funds to which
the litigation relates.  Expenses and charges incurred in the administration
of the Plan are generally paid by the Employers.  An administrative fee
relating to the issuance of Plan loans under the Loan Fund is paid by Plan
Participants.

    (d) Net Appreciation (Depreciation) in Fair Value of Investments

    The net appreciation (depreciation) in fair value of investments as
provided for in the accompanying Statements of Changes in Net Assets Available
For Benefits, With Fund Information consists of the following:

    Realized Gain (Loss) on Investments Sold or Distributed  Realized gain
(loss) is the difference between the selling price of a Fund investment and
the average cost of that Fund investment.  The average is based on revalued
and not historical cost.  Under this method, the cost of a security is equal
to its market value at the beginning of the Plan year or its acquisition cost
if acquired during the Plan year.

    Unrealized Appreciation (Depreciation) of Investments  The Plan provides
that the market value of each Fund shall be determined by the Plan Trustee on
the last day of each month.  Unrealized appreciation (depreciation) is the
difference between the market value of a Fund investment at the beginning of
the Plan year or its acquisition cost if acquired during the Plan year.

    A summary of realized gains (losses) on investments sold or distributed
and the change in unrealized appreciation (depreciation) for the years ended
December 31, 1998, 1997 and 1996 is set forth below:

    (e) Income Recognition

    Income of the Commonwealth Energy System Common Share Fund consists
primarily of dividends on its Common Shares.  The allocation of each Fund's
earnings to a Participant's account is based on the percentage of the Partici-
pant's units in the Funds and is allocated daily.  Purchases and sales of
investments are recorded on a trade-date basis.  Interest income is accrued
when earned.  Dividend income is recorded on the ex-dividend date.  Capital
gain distributions are included in dividend income.

(3) Participating Companies and Contributions

    Generally, the Plan permits Participants to make contributions of at least
one percent (1%) but not more than sixteen (16%) of their compensation as
defined in the Plan.  Effective January 1, 1998, the maximum amount a Partici-
pant may defer annually was increased to $10,000 from $9,500 previously.  This
amount is increased from time to time by the Secretary of the Treasury in
accordance with the cost of living adjustment factor prescribed in Section
402(g)(1) of the IRC.  Compensation is defined to be an employee's authorized
basic salary (including any "lump sum payment" under the authorized basic
compensation pay program), except that in the case of sales personnel compen-
sated in whole or in part by commissions, compensation shall be considered to
equal ninety percent (90%) of the average compensation earned by such employee
in the preceding four calendar quarters but not less than each employee's
authorized basic compensation.  Salary deferral contributions by employees are
made to the Plan by payroll deduction.  The Employer contributes an additional
amount equal to each employee's contribution, up to a maximum of four percent
(4%) of each employee's basic compensation rate, as previously defined, and up
to five percent (5%) for those employees no longer eligible for postretirement
health benefits.

    Effective January 1, 1998, any employee, except an employee who is
classified as a "temporary employee," who was not a Member of the Plan as of
December 31, 1997, is eligible to participate in the Plan on January 1, 1998. 
A regular employee who is hired after December 31, 1997 will become eligible
to participate in the Plan on the first day of the second month following his
or her initial date of employment.  The employer matching contribution will
not begin until the first day of the month that follows the employee's
completion of one full year of eligibility service (completion of one-thousand
(1,000) hours of service in a twelve-month period).  Previously, employees
were eligible to join the Plan upon completion of their eligibility service. 
A Participant is fully vested in and has a nonforfeitable right to the value
of his or her Member, Pay Deferral and Company Accounts at all times.

    Any eligible employee may change his or her contribution percentage as of
the first day of any month by contacting Vanguard Participant Services by the
fifteenth day of the preceding month.

    Effective January 1, 1998, an employee may file a written request with the
Board for approval of a rollover cash contribution from another qualified plan
or Individual Retirement Account to the Plan, as further discussed in "Invest-
ment Funds Accounts" below.

1998, 1,634 (96.5%) Participants were active and fully vested in the Plan.

(4) Investments

    (a) Description of Investment Funds

    Effective October 27, 1998, several Vanguard fund names were simplified
or clarified and were not the result of changes in fund management, in fund
policies or objectives, in the Plan, or in the investment options under the
Plan.  The following is a description of the twelve Investment Funds in which
a Participant may allocate his or her contributions and matching Employer
contributions:

    Commonwealth Energy System Common Share Fund - Consists of Common Shares
of Beneficial Interest of Commonwealth Energy System purchased on the open
market with employee and Employer contributions, dividends and interest
<PAGE>
<PAGE 36>

                             EMPLOYEES SAVINGS PLAN
             OF COMMONWEALTH ENERGY SYSTEM AND SUBSIDIARY COMPANIES

                          NOTES TO FINANCIAL STATEMENTS

income.  The Trustee, at its discretion, will determine the manner in which
such shares may be acquired.  The Fund provides the possibility of long-term
growth through increases in the market value of the Common Shares and the
reinvestment of dividends and interest.  Participants may not allocate more
than fifty percent (50%) of their contributions to this Fund.

    Vanguard Prime Money Market Fund - (formerly, "Vanguard Money Market
Reserves-Prime Portfolio")  A mutual fund that seeks the highest level of
income consistent with maintaining a stable share price of $1.  Value is added
primarily by emphasizing specific issues and sectors of the money market that
appear to be attractively priced based upon historical yield spread relation-
ships.  The fund invests in short-term, high-quality money market instruments
issued by financial institutions, nonfinancial corporations, the U.S. govern-
ment and federal agencies.  Its holdings may include certificates of deposit,
bank-guaranteed securities, corporate notes, other money market instruments,
U.S. Treasury and government agency securities and repurchase agreements on
such securities.  The average maturity of the fund's holdings will be 90 days
or less.

    Vanguard Windsor II Fund -  A mutual fund that seeks long-term growth of
capital and income from dividends.  As a secondary objective, the fund seeks a
reasonable level of current income.  The fund invests in a diversified group
of out-of-favor stocks of large capitalization companies.  The stocks that
comprise the fund sell at prices below the overall market average compared to
their dividend income and future return potential.

    Vanguard Short-Term Corporate Fund - (formerly, "Vanguard Fixed Income
Securities Fund-Short-Term Corporate Portfolio")  A mutual fund that seeks
income while maintaining a high degree of stability of principal.  The fund
invests in short-term bonds, including investment-grade corporate and U.S.
Treasury securities.  It maintains an average maturity of two to three years
to reduce the risk of share-price fluctuations in response to changing
interest rates.

    Vanguard Wellington Fund - A mutual fund that seeks income and long-term
growth of capital without undue risk to capital.  The fund's assets are
divided between common stocks and bonds, with an average of 65% of assets in
stocks and 35% in bonds.  The fund invests in dividend-paying large- and mid-
capitalization stocks of well-established companies whose prospects are
improving, but whose values have yet to be recognized in the marketplace.  The
objective is to identify these companies before their values are recognized in
the marketplace.

    Vanguard International Growth Fund - (formerly, "Vanguard Internation-
al Growth Portfolio")  A mutual fund that seeks long-term growth of capital by
investing in stocks of high-quality companies based outside the United States. 
The fund invests 60% to 70% of its assets in companies with sustainable
competitive advantages and strong prospects for long-term growth.  To supple-
ment these core holdings and boost its allocations to particularly attractive
markets, the fund also invests in large stocks in those markets that are
expected to have particularly strong near-term returns.

                          NOTES TO FINANCIAL STATEMENTS

    Vanguard Extended Market Index Fund - (formerly, "Vanguard Index Trust -
Extended Market Portfolio")  A mutual fund that seeks  long-term growth of
capital that attempts to match the performance of the Wilshire 4500 Equity
Index, an unmanaged index consisting primarily of mid- and small-capitaliza-
tion companies.  The fund invests in a large sample of stocks that matches
certain characteristics of the index such as industry weightings, market
capitalization and dividend yield.  Fund transaction costs, consisting of
bid/ask spreads, commissions and market impact, are not reflected in the
performance of market indexes.  To minimize tracking errors and to allocate
these costs equitably, the fund assesses a 0.25% transaction fee on shares
purchased.

    Vanguard Explorer Fund - A mutual fund that seeks long-term growth of
capital by investing in a diversified group of small-company stocks with
prospects for above-average growth.

    Vanguard LifeStrategy Funds - Consists of four funds that attempt to
maximize total investment return (i.e. capital growth and income), subject to
different investment guidelines and asset allocation policies.  These Funds
invest in other Vanguard mutual funds, representing different combinations of
stocks, bonds and cash reserves, and reflecting varying degrees of investment
risk and reward.  The four funds are:
    The Income Fund seeks a high level of income.
    The Conservative Growth Fund seeks a high level of income and moderate
    long-term growth of capital and income.
    The Moderate Growth Fund seeks to provide a reasonable level of income
    and long-term growth of capital and income.
    The Growth Fund seeks to provide long-term growth of capital and income.

    (b)  Investment Funds Accounts

    The Board maintains for each Participant in the Plan, under each Fund in
which all or part of his or her contributions and the applicable Employer
contributions are invested, a separate Member Account that includes a Pay
Deferral Account for current pre-tax contributions.  In addition, the Member
Account may include previous after-tax contributions.  The Board also main-
tains a separate Company Account (for each Participant) that includes Employer
contributions made on behalf of Participants.  These Accounts reflect the
portion of each Participant's interest in the Fund that is attributable to the
contributions to such Accounts.

    The Plan permits Participants to transfer amounts between Funds on a
daily basis, subject to certain limitations.

    Effective January 1, 1998, a Participant may request to rollover an
"eligible rollover distribution" as defined in Section 402(c)(4) of the IRC
from a qualified plan or a distribution from a conduit Individual Retirement
Account to the Plan.  The Board will maintain a separate Rollover Account for
each Participant and all Participants are fully vested in their Rollover
Account at all times.

                          NOTES TO FINANCIAL STATEMENTS

    The Plan Trustee may, at its discretion, temporarily invest funds desig-
nated for a particular Fund in short-term interest-bearing securities or may
retain certain amounts of cash in each Fund without interest being credited
thereon, for the purpose of more effectively timing the purchase of invest-
ments or liquidity needs for the several Funds.  All contributions are
transmitted weekly to the Plan Trustee.

    A Participant's choice of contribution allocation to eligible Funds will
continue until changed by such Participant.  Investment designations may be
changed daily by contacting a Vanguard Participant Services representative.

    All interest, dividends, and other income, as well as any cash from the
sale or exchange of securities or other property produced by each of the Funds
will be reinvested in the same Fund that produced such interest, dividends and
other income.

(5) Party in Interest

    COM/Energy is a "party in interest" as that term is defined in Section
3.14 of ERISA.

    Certain transactions involving the acquisition and distribution of
securities are made at the direction of Participants in the Plan who elect to
participate in the Commonwealth Energy System Common Share Fund as one of
their investment options.  These transactions are reflected in the accompany-
ing financial statements at market value and are net of brokerage commissions
relating to the acquisition of these securities.

    During the years ended December 31, 1998, 1997 and 1996, the Plan Trustee
purchased Common Shares of Commonwealth Energy System, made distributions of
Common Shares to Participants and sold Common Shares to accommodate cash
distributions as follows:

                       Commonwealth Energy System Common Share Fund       
                   Shares                       Shares Sold / Distributed 
                 Purchased        Cost         Shares      Aggregate Value

     1998         179,601      $6,570,462      209,450         $3,187,551
     1997         198,067       4,667,158      721,145         10,862,830
     1996         258,747       9,134,782      453,158          8,876,352

     The Plan Trustee also represents a party in interest to the Plan due to
the Plan's investments in Funds of the Plan Trustee.

(6)  Loans to Plan Participants

     Participants may request a loan from the Plan for a minimum amount of
$1,000.  The amount of the loan shall not exceed the lesser of $50,000 or
fifty percent (50%) of the balance of the Participant's total value in the
various Funds of the Plan.  The interest rate on a loan is based on the prime
rate at BankBoston, N.A. on the first day of the quarter preceding the loan
request plus one percent.  Participants may choose a repayment period of one

                          NOTES TO FINANCIAL STATEMENTS

to five years.  For the years 1998, 1997 and 1996, the interest rates ranged
from 8.75% to 9.50%.

     Eligible Participants have the option of securing a second loan from the
Plan including requests for up to a thirty (30) year loan to purchase a
primary residence.

(7)  Reportable Transactions

     Under ERISA, transactions which, individually or in the aggregate with
the same issuer, exceed five percent (5%) of the current value of Plan assets
at the beginning of the Plan year are "reportable transactions."  Details of
these reportable transactions are set forth in Schedule II of this report.

(8)  Amendment and Termination

     COM/Energy expects the Plan to be permanent, but since future conditions
affecting the Plan cannot be anticipated or foreseen, COM/Energy reserves the
right by action of the Board of Trustees of COM/Energy and Boards of Directors
of the Participating Companies to terminate or amend the Plan in whole or in
part at any time and from time to time.  In addition, by action only of the
Board's officers, each of the Participating Companies may make any modifica-
tions or amendments to the Plan that are necessary or appropriate to maintain
the Plan as a plan meeting the requirements of Section 401 of the IRC, or any
other applicable provisions of the IRC as now in effect, or hereafter amended,
or the provisions of ERISA and the regulations or rulings issued thereunder. 
Notwithstanding the foregoing, it shall be impossible for any part of the
Trust Fund, after the payment of expenses, to be used for or diverted to any
purpose other than for the exclusive benefit of the Participants or their
beneficiaries, either by amendment, operation or termination of the Plan, or
by other means.  COM/Energy does not expect to terminate the Plan.  However,
as discussed in Note 1, COM/Energy expects to merge with BEC Energy during the
second half of 1999 and this event could have an impact on the Plan.

     Upon termination of the Plan or upon permanent discontinuance of contri-
butions under the Plan, the interest of each person having an interest in the
Trust Fund shall be determined as of that date.  The interest of each such
person in the Trust Fund shall be set aside by the Plan Trustee for the
special account of such Participant or his or her beneficiary.  Thereafter,
after payments of expenses, distribution shall be made in accordance with the
provisions of the Plan.
