                           BOSTON EDISON SAVINGS PLAN
                         Notes to Financial Statements

A.  Plan Description
    ----------------
The Boston Edison Savings Plan (the Plan) was established effective January
1, 1986 to provide retirement benefits for participating employees of
Boston Edison Company (the Company) through a program of salary-reduction
contributions.  The Plan is subject to the rules and regulations of the
Employee Retirement Income Security Act of 1974 (ERISA).  The Plan is
qualified under section 401(a) of the Internal Revenue Code (the Code) and
utilizes the special federal tax deferral features of section 401(k) of the
Code.  The Company is the only employer participating in the Plan.  The
plan administrators are the Boston Edison Retirement Plans Committee and
the Boston Edison Pension Management Committee.

The Company matches a percentage of each participant's contribution, up to
a maximum of 6% of the participant's compensation.  The percentages matched
were 50% in 1991, 75% in 1992 and 100% in 1993.  The match is made entirely
in Company common stock.  Employees are immediately fully vested in the
match.

Employees are eligible to join the Plan at specified times at age 21 or
older with one year of service, at age 35, or after four years of service,
regardless of age.  Employees participating in the Plan elect to make
contributions of at least 2% but not more than 15% of their compensation as
defined in the Plan.  Members of the Plan are fully vested at all times.
Members are not subject to federal taxes on contributions nor the earned
income until such time as distribution or withdrawal is made.

Investments in the Plan are directed by the individual plan participants.
There are currently five investment choices offered under the Plan:  four
invested in mutual funds (Asset Manager, Magellan, Retirement Government
Money Market and U.S. Equity Index) managed by Fidelity Investments
(Fidelity) and one invested in Company common stock.  Effective January 1,
1995, four additional investment choices will be offered:  three invested
in mutual funds (Intermediate Bond Fund, International Growth and Income
Fund and Disciplined Equity Fund) managed by Fidelity, and a Self-Directed
Brokerage Account offered by Fidelity through which participants can invest
in a variety of securities.

At December 31, 1993, there were 1,627 participants in the Plan, of whom
954, 1,160, 516, 238 and 1,607 were invested in the Fidelity Asset Manager,
Magellan, Retirement Government Money Market, U.S. Equity Index and Boston
Edison Company Common Stock funds, respectively.

While it is the current intention of the Company to continue the Plan for
as long as the provisions of the Internal Revenue code permit, neither the
making of contributions nor the continuance of the Plan is assumed by the
Company as a contractual obligation.  In the event of Plan termination, the
assets will be distributed to participants to the extent of their
individual allocations, in accordance with the Plan's distribution
provisions.

B.   Summary of Significant Accounting Policies
     ------------------------------------------
     Basis of Accounting
     -------------------
     The Plan's financial statements have been prepared under the accrual
     method of accounting and in accordance with the rules and regulations
     of ERISA.

     Investments Valuation
     ---------------------
     Plan investments held by Fidelity, the trustee of the Plan, are stated
     at fair value.  Shares of registered investment companies are valued
     at quoted market prices which represent the net asset value of shares
     held by the Plan at year-end.  The Company common stock is valued at
     its quoted market price.  Participant notes receivable are valued at
     cost which approximates fair value.

     Expenses
     --------
     Fees for investment advisory and other services provided to the
     Fidelity funds are charged directly to each of the Fidelity funds.
     Participants pay a commission on the purchase and sale of Company
     stock.  All other expenses of administering the Plan are currently
     paid by the Company.  Beginning January 1, 1995, loan fees and self-
     directed brokerage fees will be paid by participants.

     Net Appreciation/(Depreciation) in the Fair Value of Investments
     ----------------------------------------------------------------
     Gains and losses are realized upon distributions (including
     withdrawals) to participants and the transfer of all or a portion of a
     participant's account between investment choices.

     The Plan presents in the statement of changes in net assets the net
     appreciation (depreciation) in the fair value of its investments which
     consists of the realized gains or losses and the unrealized
     appreciation (depreciation) on those investments.

     Payment of Benefits
     -------------------
     Benefits are recorded when paid.

     Other
     -----
     Dividend income is recorded on the ex-dividend date.

C.   Contributions
     -------------
     Salary reduction contributions made on behalf of members and Company
     matching contributions are recorded in the period payroll deductions
     are made from members.  Contributions receivable at December 31
     represents amounts withheld from participants and the corresponding
     Company matching contributions subsequently deposited to the Plan in
     the following month.

D.   Transfers Between Investment Choices and Other Savings Plans
     ------------------------------------------------------------
     Plan participants may, with certain limitations, elect to transfer
     their elective contribution account balances from any investment
     choice or choices to any of the other choices offered by the Plan.



                                       8


<PAGE>   10





     If a participant ceases to be a member in the Plan and subsequently
     participates in either the Boston Edison Negotiated Savings Plan for
     Production and Maintenance Employees or the Boston Edison Negotiated
     Savings Plan for Office, Technical & Professional Employees, the
     participant's account balance in the Plan will be transferred to the
     other plan.

E.   Participant Notes
     -----------------
     Participants in the Plan for at least 24 months may obtain a loan from
     the Plan from the balance in their elective contribution account.
     Effective July 1, 1994, loan eligibility will be reduced to 12 months
     of participation.  The loan may not be less than $1,000 nor exceed the
     lesser of $50,000, or 50% of the market value of the participant's
     elective contribution account.  Loans must be repaid to the
     participant's account over a period not to exceed five years (unless
     the loan is for the purchase of a principal residence) via payroll
     deductions.  The annual interest rate is modified from time to time to
     reflect changes in the prime rate or other market interest indicators.
     Loan transactions are treated as a transfer to (from) the investment
     funds from (to) the Participant Notes fund.

F.   Related Party Transactions
     --------------------------
     Certain Plan investments are shares of mutual funds managed by
     Fidelity.  Fidelity is the trustee as defined by the Plan and
     therefore these transactions qualify as party-in-interest.

     Boston Edison Company is a party-in-interest as that term is defined
     in section 3.14 of ERISA.

H.   Tax Status
     ----------
     The Internal Revenue Service has determined and informed the Company
     by a letter dated July 1, 1987, that the Plan is designed in
     accordance with applicable sections of the Internal Revenue Code
     (IRC).  The Plan has been amended since receiving the determination
     letter.  However, the Plan administrator and the Plan's counsel
     believe that the Plan is designed and is currently being operated in
     compliance with the applicable requirements of the IRC.

I.   Reclassification
     ----------------
     Certain prior period amounts on the financial statements were
     reclassified to conform with current presentation.

                       REPORT OF INDEPENDENT ACCOUNTANTS
                       ---------------------------------


To the Boston Edison Retirement Plans Committee:


     We have audited the accompanying statements of net assets available
for benefits including the schedules of investments of the Boston Edison
Savings Plan as of December 31, 1993 and 1992, and the related statements
of changes in net assets available for benefits for each of the three years
in the period ended December 31, 1993.  These financial statements are the
responsibility of the Plan's management.  Our responsibility is to express
an opinion on these financial statements based on our audits.

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

     In our opinion, the financial statements referred to above present
fairly, in all material respects, the net assets available for benefits of
the Boston Edison Savings Plan as of December 31, 1993 and 1992, and the
changes in net assets available for benefits for each of the three years in
the period ended December 31, 1993 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.  The supplemental schedules of
investments held at December 31, 1993 and reportable transactions for the
year ended December 31, 1993 are presented for purposes of additional
analysis and are not a required part of the basic financial statements but
are supplementary 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 Information in the statement of
changes in net assets available for benefits is presented for the purpose
of additional analysis rather than to present the 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 audit 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.

               BOSTON EDISON NEGOTIATED SAVINGS PLAN FOR OFFICE,
                       TECHNICAL & PROFESSIONAL EMPLOYEES
                         Notes to Financial Statements

A.  Plan Description
    ----------------
The Boston Edison Negotiated Savings Plan for Office, Technical &
Professional Employees (the Plan) was established effective January 1, 1991
to provide retirement benefits for participating eligible employees of
Boston Edison Company (the Company) through a program of salary-reduction
contributions.  The Plan is subject to the rules and regulations of the
Employee Retirement Income Security Act of 1974 (ERISA).  The Plan is
intended to be qualified under section 401(a) of the Internal Revenue Code
(the Code) and to utilize the special federal tax deferral features of
section 401(k) of the Code.  The Company is the only employer participating
in the Plan.  The plan administrators are the Boston Edison Retirement
Plans Committee and the Boston Edison Pension Management Committee.

The Company currently contributes a matching amount under the Plan equal to
50% of each participant's contribution, up to a maximum of 6% of the
participant's compensation.  The maximum Company match will increase to 7%
of the participant's compensation effective July 1, 1995 and to 8%
effective July 1, 1997. The match is made entirely in Company common stock.
Employees are immediately fully vested in the match.

Employees are eligible to join the Plan at specified times at age 21 or
older with one year of service, at age 35, or after four years of service,
regardless of age.  Employees participating in the Plan elect to make
contributions of at least 2% but not more than 15% of their compensation as
defined in the Plan.  Effective July 1, 1994, the maximum allowable
percentage contribution will increase to 16%.  Members of the Plan are
fully vested at all times.  Members are not subject to federal taxes on
contributions nor the earned income until such time as distribution or
withdrawal is made.

Investments in the Plan are directed by the individual plan participants.
There are currently five investment choices offered under the Plan:  four
invested in mutual funds (Asset Manager, Magellan, Retirement Government
Money Market and U.S. Equity Index) managed by Fidelity Investments
(Fidelity) and one invested in Company common stock.  Effective January 1,
1995, four additional investment choices will be offered:  three invested
in mutual funds (Intermediate Bond Fund, International Growth and Income
Fund and Disciplined Equity Fund) managed by Fidelity, and a Self-Directed
Brokerage Account offered by Fidelity through which participants can invest
in a variety of securities.

At December 31, 1993, there were 994 participants in the Plan, of whom 485,
692, 334, 128 and 982 were invested in the Fidelity Asset Manager,
Magellan, Retirement Government Money Market, U.S. Equity Index and Boston
Edison Company Common Stock funds, respectively.

While it is the current intention of the Company to continue the Plan for
as long as the provisions of the Internal Revenue Code permit, neither the
making of contributions nor the continuance of the Plan is assumed by the
Company as a contractual obligation except as provided in any relevant
collective bargaining agreements.  In the event of Plan termination, the
assets will be distributed to participants to the extent of their
individual allocations, in accordance with the Plan's distribution
provisions.

B.   Summary of Significant Accounting Policies
     ------------------------------------------
     Basis of Accounting
     -------------------
     The Plan's financial statements have been prepared under the accrual
     method of accounting and in accordance with the rules and regulations
     of ERISA.

     Investments Valuation
     ---------------------
     Plan investments held by Fidelity, the trustee of the Plan, are stated
     at fair value.  Shares of registered investment companies are valued
     at quoted market prices which represent the net asset value of shares
     held by the Plan at year-end.  The Company common stock is valued at
     its quoted market price.  Participant notes receivable are valued at
     cost which approximates fair value.

     Expenses
     --------
     Fees for investment advisory and other services provided to the
     Fidelity funds are charged directly to each of the Fidelity funds.
     Participants pay a commission on the purchase and sale of Company
     stock.  All other expenses of administering the Plan are currently
     paid by the Company.  Beginning January 1, 1995, loan fees and self-
     directed brokerage fees will be paid by participants.

     Net Appreciation/(Depreciation) in the Fair Value of Investments
     ----------------------------------------------------------------
     Gains and losses are realized upon distributions (including
     withdrawals) to participants and the transfer of all or a portion of a
     participant's account between investment choices.

     The Plan presents in the statement of changes in net assets the net
     appreciation (depreciation) in the fair value of its investments which
     consists of the realized gains or losses and the unrealized
     appreciation (depreciation) on those investments.

     Payment of Benefits
     -------------------
     Benefits are recorded when paid.

     Other
     -----
     Dividend income is recorded on the ex-dividend date.

C.   Contributions
     -------------
     Salary reduction contributions made on behalf of members and Company
     matching contributions are recorded in the period payroll deductions
     are made from members.  Contributions receivable at December 31
     represents amounts withheld from participants and the corresponding
     Company matching contributions subsequently deposited to the Plan in
     the following month.  Contributions receivable at December 31, 1993
     and 1992 were as follows:

D.   Transfers Between Investment Choices and Other Savings Plans
     ------------------------------------------------------------
     Plan participants may, with certain limitations, elect to transfer
     their elective contribution account balances from any investment
     choice or choices to any of the other choices offered by the Plan.

     If a participant ceases to be a member in the Plan and subsequently
     participates in either the Boston Edison Savings Plan or the Boston
     Edison Negotiated Savings Plan for Production and Maintenance
     Employees, the participant's account balance in the Plan will be
     transferred to the other plan.

E.   Participant Notes
     -----------------
     Participants in the Plan for at least 24 months may obtain a loan from
     the Plan from the participant's elective contribution account.
     Effective July 1, 1994, loan eligibility will be reduced to 12 months
     of participation.  The loan may not be less than $1,000 nor exceed the
     lesser of $50,000, or 50% of the market value of the participant's
     elective contribution account.  Loans must be repaid to the
     participant's account over a period not to exceed five years (unless
     the loan is for the purchase of a principal residence) via payroll
     deductions.  The annual interest rate is modified from time to time to
     reflect changes in the prime rate or other market interest indicators.
     Loan transactions are treated as a transfer to (from) the investment
     funds from (to) the Participant Notes fund.

F.   Plan Transfer
     -------------
     Prior to January 1, 1991, participants in the Plan were members of the
     Boston Edison Negotiated Savings Plan (renamed the Boston Edison
     Negotiated Savings Plan for Production and Maintenance Employees as of
     January 1, 1991).  The participants' balances were transferred to the
     Plan effective January 1, 1991, pursuant to a collective bargaining
     agreement involving certain employees of the Company.  The market
     value of the balances transferred January 1, 1991 totaled $4,532,079
     ($4,456,911 at cost).

G.   Related Party Transactions
     --------------------------
     Certain Plan investments are shares of mutual funds managed by
     Fidelity.  Fidelity is the trustee as defined by the Plan and
     therefore these transactions qualify as party-in-interest.

     Boston Edison Company is a party-in-interest as that term is defined
     in section 3.14 of ERISA.

</TABLE>


     Contributions are recorded on the Form 5500 when received.

     The adjustment in 1991 is due to the transfer of Plan assets from
     Boston Edison Negotiated Savings Plan for Production and Maintenance
     Employees.  There is an offsetting adjustment shown on that Plan's
     reconcilement to the Form 5500.

I.   Tax Status
     ----------

                       REPORT OF INDEPENDENT ACCOUNTANTS
                       ---------------------------------


To the Boston Edison Retirement Plans Committee:


     We have audited the accompanying statements of net assets available for
benefits including the schedules of investments of the Boston Edison
Negotiated Savings Plan for Office, Technical & Professional Employees as
of December 31, 1993 and 1992, and the related statements of changes in net
assets available for benefits for each of the three years in the period
ended December 31, 1993.  These financial statements are the responsibility
of the Plan's management.  Our responsibility is to express an opinion on
these financial statements based on our audits.

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

     In our opinion, the financial statements referred to above present
fairly, in all material respects, the net assets available for benefits of
the Boston Edison Negotiated Savings Plan for Office, Technical and
Professional Employees as of December 31, 1993 and 1992, and the changes in
net assets available for benefits for each of the three years in the period
ended December 31, 1993 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.  The supplemental schedules of
investments held at December 31, 1993 and reportable transactions for the
year ended December 31, 1993 are presented for purposes of additional
analysis and are not a required part of the basic financial statements but
are supplementary 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 Information in the statement of
changes in net assets available for benefits is presented for the purpose
of additional analysis rather than to present the 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 audit 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.

                   BOSTON EDISON NEGOTIATED SAVINGS PLAN FOR
                      PRODUCTION AND MAINTENANCE EMPLOYEES
                         Notes to Financial Statements

A.  Plan Description
    ----------------
The Boston Edison Negotiated Savings Plan for Production and Maintenance
Employees (the Plan) was established effective October 1, 1986 to provide
retirement benefits for participating eligible employees of Boston Edison
Company (the Company) through a program of salary-reduction contributions.
The Plan is subject to the rules and regulations of the Employee Retirement
Income Security Act of 1974 (ERISA).  The Plan is qualified under section
401(a) of the Internal Revenue Code (the Code) and utilizes the special
federal tax deferral features of section 401(k) of the Code.  The Company,
which is not currently a contributor under the Plan, is the only employer
participating in the Plan.  The plan administrators are the Boston Edison
Retirement Plans Committee and the Boston Edison Pension Management
Committee.

Effective July 1, 1994, the Company will contribute a matching amount under
the Plan equal to 50% of each participant's contribution, up to a maximum
of 6% of the participant's compensation.   The match will be made entirely
in Company common stock.  Employees will be immediately fully vested in the
match.

Employees are eligible to join the Plan at specified times at age 21 or
older with one year of service, at age 35, or after four years of service,
regardless of age.  Employees participating in the Plan elect to make
contributions of at least 2% but not more than 15% of their compensation as
defined in the Plan.  Effective July 1, 1994, the maximum allowable
percentage contribution will increase to 17%.  Members of the Plan are
fully vested at all times.  Members are not subject to federal taxes on
contributions nor the earned income until such time a distribution or
withdrawal is made.

Investments in the Plan are directed by the individual plan participants.
There are currently five investment choices offered under the Plan:  four
invested in mutual funds (Asset Manager, Magellan, Retirement Government
Money Market and U.S. Equity Index) managed by Fidelity Investments
(Fidelity) and one invested in Company common stock.  Effective January 1,
1995, four additional investment choices will be offered:  three invested
in mutual funds (Intermediate Bond Fund, International Growth and Income
Fund and Disciplined Equity Fund) managed by Fidelity, and a Self-Directed
Brokerage Account offered by Fidelity through which participants can invest
in a variety of securities.

At December 31, 1993, there were 1,425 participants in the Plan, of whom
690, 989, 369, 163 and 832 were invested in the Fidelity Asset Manager,
Magellan, Retirement Government Money Market, U.S. Equity Index and Boston
Edison Company Common Stock funds, respectively.

While it is the current intention of the Company to continue the Plan for
as long as the provisions of the Internal Revenue Code permit, neither the
making of contributions nor the continuance of the Plan is assumed by the
Company as a contractual obligation except as provided in any relevant
collective bargaining agreements.  In the event of Plan termination, the
assets will be distributed to participants to the extent of their
individual allocations, in accordance with the Plan's distribution
provisions.

B.   Summary of Significant Accounting Policies
     ------------------------------------------
     Basis of Accounting
     -------------------
     The Plan's financial statements have been prepared under the accrual
     method of accounting and in accordance with the rules and regulations
     of ERISA.

     Investments Valuation
     ---------------------
     Plan investments, held by Fidelity, the trustee of the Plan, are
     stated at fair value.  Shares of registered investment companies are
     valued at quoted market prices which represent the net asset value of
     shares held by the Plan at year-end.  The Company common stock is
     valued at its quoted market price.  Participant notes receivable are
     valued at cost which approximates fair value.

     Expenses
     --------
     Fees for investment advisory and other services provided to the
     Fidelity funds are charged directly to each of the Fidelity funds.
     Participants pay a commission on the purchase and sale of Company
     stock.  All other expenses of administering the Plan are currently
     paid by the Company.  Beginning January 1, 1995, loan fees and self-
     directed brokerage fees will be paid by participants.

     Net Appreciation/(Depreciation) in the Fair Value of Investments
     ----------------------------------------------------------------
     Gains and losses are realized upon distributions (including
     withdrawals) to participants and the transfer of all or a portion of a
     participant's account between investment choices.

     The Plan presents in the statement of changes in net assets the net
     appreciation (depreciation) in the fair value of its investments which
     consists of the realized gains or losses and the unrealized
     appreciation (depreciation) on those investments.

     Payment of Benefits
     -------------------
     Benefits are recorded when paid.

     Other
     -----
     Dividend income is recorded on the ex-dividend date.

C.   Contributions
     -------------
     Salary reduction contributions made on behalf of members are recorded
     in the period payroll deductions are made from members.  Contributions
     receivable at December 31 represents amounts withheld from
     participants subsequently deposited to the Plan in the following
     month.  Contributions receivable at December 31, 1993 and 1992 were as
     follows:

D.   Transfers Between Investment Choices and Other Savings Plans
     ------------------------------------------------------------
     Plan participants may, with certain limitations, elect to transfer
     their account balances from any investment choice or choices to any of
     the other choices offered by the Plan.

     If a participant ceases to be a member in the Plan and subsequently
     participates in either the Boston Edison Savings Plan or the Boston
     Edison Negotiated Savings Plan for Office, Technical & Professional
     Employees, the participant's account balance in the Plan will be
     transferred to the other plan.

E.   Participant Notes
     -----------------
     Participants in the Plan for at least 24 months may obtain a loan from
     the Plan from the balance in their elective contribution account.
     Effective July 1, 1994, loan eligibility will be reduced to 12 months
     of participation.  The loan may not be less than $1,000 nor exceed the
     lesser of $50,000 or 50% of the participant's account.  Loans must be
     repaid to the participant's account over a period not to exceed five
     years (unless the loan is for the purchase of a principal residence)
     via payroll deductions.  The annual interest rate is modified from
     time to time to reflect changes in the prime rate or other market
     interest indicators.  Loan transactions are treated as a transfer to
     (from) the investment funds from (to) the Participant Notes fund.

F.   Plan Transfer
     -------------
     Effective January 1, 1991, certain participant balances with a market
     value of $4,532,079 ($4,456,911 at cost) that were included in the
     Plan during 1990 were transferred to a new plan, The Boston Edison
     Negotiated Savings Plan for Office, Technical & Professional
     Employees, pursuant to a collective bargaining agreement involving
     certain employees of the Company.

G.   Related Party Transactions
     --------------------------
     Certain Plan investments are shares of mutual funds managed by
     Fidelity.  Fidelity is the trustee as defined by the Plan and
     therefore these transactions qualify as party-in-interest.

     Boston Edison Company is a party-in-interest as that term is defined
     in section 3.14 of ERISA.

     Contributions are recorded on the Form 5500 when received.

     The adjustment in 1991 is due to the transfer of Plan assets to Boston
     Edison Negotiated Savings Plan for Office, Technical & Professional
     Employees.  There is an offsetting adjustment shown on that Plan's
     reconcilement to the Form 5500.

I.   Tax Status
     ----------
     The Internal Revenue Service has determined and informed the Company
     by a letter dated September 28, 1987, that the Plan is designed in
     accordance with applicable sections of the Internal Revenue Code
     (IRC).  The Plan has been amended since receiving the determination
     letter.  However, the Plan administrator and the Plan's counsel
     believe that the Plan is designed and is currently being operated in
     compliance with the applicable requirements of the IRC.

J.   Reclassification
     ----------------
     Certain prior period amounts on the financial statements were
     reclassified to conform with current presentation.

                       REPORT OF INDEPENDENT ACCOUNTANTS
                       ---------------------------------


To the Boston Edison Retirement Plans Committee:


     We have audited the accompanying statements of net assets available
for benefits including the schedules of investments of the Boston Edison
Negotiated Savings Plan for Production and Maintenance Employees as of
December 31, 1993 and 1992, and the related statements of changes in net
assets available for benefits for each of the three years in the period
ended December 31, 1993.  These financial statements are the responsibility
of the Plan's management.  Our responsibility is to express an opinion on
these financial statements based on our audits.

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

     In our opinion, the financial statements referred to above present
fairly, in all material respects, the net assets available for benefits of
the Boston Edison Negotiated Savings Plan for Production and Maintenance
Employees as of December 31, 1993 and 1992, and the changes in net assets
available for benefits for each of the three years in the period ended
December 31, 1993 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.  The supplemental schedules of
investments held at December 31, 1993 and reportable transactions for the
year ended December 31, 1993 are presented for purposes of additional
analysis and are not a required part of the basic financial statements but
are supplementary 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 Information in the statement of
changes in net assets available for benefits is presented for the purpose
of additional analysis rather than to present the 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.
