              COMMONWEALTH ENERGY SYSTEM AND SUBSIDIARY COMPANIES
                    NOTES TO CONDENSED FINANCIAL STATEMENTS

(1)      Accounting Policies

         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 system's significant accounting policies are described in Note 1
   of Notes to Consolidated Financial Statements included in its 1993 Annual
   Report on Form 10-K filed with the Securities and Exchange Commission. 
   For interim reporting purposes, the system follows these same basic
   accounting policies but considers each interim period as an integral part
   of an annual period and makes allocations of certain expenses to interim
   periods based upon estimates of such expenses for the year.

         Regulated subsidiaries of the System have established various
   regulatory assets in cases where the Massachusetts Department of Public
   Utilities (DPU) and/or the Federal Energy Regulatory Commission (FERC)
   have permitted, or are expected to permit, recovery of specific costs over
   time.  At March 31, 1994, principal regulatory assets included in deferred
   charges were $21.4 million for transition costs associated with FERC Order
   636, $14.9 million for unrecovered plant and decommissioning costs for the
   Yankee Atomic nuclear plant, $14.7 million for abandonment and noncon-
   struction costs related to the Seabrook project, $14.2 million for post-
   retirement benefits costs including pensions, $7.3 million in litigation
   costs associated with a settlement agreement with Boston Edison Company
   relative to the Pilgrim nuclear plant and $7.3 million related to deferred
   income taxes.  The more significant regulatory liabilities, reflected in
   deferred credits, include $17.8 million related to income taxes.

         Generally, expenses which relate to more than one interim period are
   allocated to other periods to more appropriately match revenues and
   expenses.  Principal items of expense which are allocated other than on
   the basis of passage of time are depreciation and property taxes of the
   gas subsidiary, Commonwealth Gas Company (Commonwealth Gas).  These
   expenses are recorded for interim reporting purposes based upon projected
   gas revenue.  Income tax expense is recorded using the statutory rates in
   effect applied to book income subject to tax for each interim period.

         The unaudited financial statements for the periods ended March 31,
   1994 and 1993, reflect, in the opinion of the System, all adjustments
   necessary to summarize fairly the results for such periods.  In addition,
   certain prior period amounts are reclassified from time to time to con-
   form with the presentation used in the current period's financial
   statements.

         The results for interim periods are not necessarily indicative of
   results for the entire year because of seasonal variations in the
   consumption of energy and Commonwealth Gas' seasonal rate structure.

(2)      Commitments and Contingencies

         (a) Construction

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

         (b)   Decommissioning of Nuclear Power Plants

         The system, through Canal Electric Company (Canal), has a 3.52%
   joint-ownership interest in the Seabrook nuclear power plant.  Canal and
   the other joint owners have established a Seabrook Nuclear Decommissioning
   Financing Fund to cover post operational decommissioning costs.  The
   estimated cost to decommission the plant is $370 million, in 1994 dollars,
   through March 31, 1994.  Canal's share, less its share of the market value
   of the decommissioning trust, would amount to approximately $12.1 million.

         The system also has ownership interests in four nuclear generating
   facilities in New England and is obligated to pay its proportionate share
   of the capacity and energy costs associated with these units, which
   include depreciation, operations and maintenance, a return on invested
   capital and the estimated cost of decommissioning the nuclear plants at
   the end of their estimated service lives.  Pertinent information with
   respect to projected decommissioning costs, in 1993 dollars, resulting
   from life-of-the-unit contracts from these units is as follows:

    *    On February 26, 1992, the Board of Directors of Yankee Atomic
         Electric Company agreed to permanently discontinue power operation of
         its plant and decommission the facility.  Cambridge Electric Light
         Company's (Cambridge) and Commonwealth Electric Company's (Common-
         wealth Electric) respective 2% and 2.5% investment in Yankee Atomic
         is approximately $1 million.  The companies' estimated decommission-
         ing costs include their unrecovered share of all costs associated
         with the shutdown of the facility, recovery of its plant investment,
         and decommissioning and closing the plant.  This amount is reflected
         in the accompanying Balance Sheets as a liability and a corresponding
         regulatory asset.

         (c) Environmental

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

         (d) FERC Order No. 636

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

         As a result of implementing Order 636, each pipeline company is 
    allowed to collect certain "transition costs" from their customers. 
    Commonwealth Gas has been billed a total of approximately $18.2 million
    from Tennessee Gas Pipeline Company, Algonquin Gas Transmission Company
    and Texas Eastern Transmission Company through March 31, 1994.  It is
    anticipated that as much as $45 million in transition costs could be
    sought by these suppliers through a series of FERC filings over the 12 to
    24 month period that began on June 1, 1993.  The largest element of the
    aforementioned transition costs results from the pipelines' need to buy
    out gas supply contracts entered into prior to Order 636.  The total
    amount of such costs ultimately billed to Commonwealth Gas will vary
    depending on the success of the pipelines in negotiating settlements with
    their former suppliers, and final review by the FERC.  Commonwealth Gas is
    actively reviewing the prudency of transition costs billed in order to
    minimize costs to its customers.  Commonwealth Gas has recorded its
    estimated liability based on amounts incurred by the respective pipelines
    as of March 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 $21.4 million is
    reflected in deferred charges as of March 31, 1994.  In addition, a
    related liability of $11.8 million is reflected in deferred credits. 
    Also, approximately $7.9 million of the amount paid to the pipeline
    companies relates to gas inventory costs being allocated new storage      
    services under Order 636.  Commonwealth Gas will recover these inventory
    costs through the CGA.

Item 2.  Management's Discussion and Analysis of Financial Condition
         and Results of Operations

         Financial Condition

         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). 
    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 purchases
    100% of all subsidiary common stock issues and provides, to the extent
    possible, a portion of the subsidiaries' short-term financing needs. 
    These capital resources provide the funds required for the subsidiary
    companies' construction programs, current operations, debt service and
    other capital requirements.

         For the first three months of 1994, cash flows from operating
    activities amounted to approximately $67.7 million and reflect net income
    of $28 million and non-cash items such as depreciation ($13.2 million),
    amortization ($3.5 million) and deferred income taxes (net of investment
    tax credits) which amounted to $478,000.  The change in working capital
    since December 31, 1993, exclusive of cash and interim financing, amounted
    to $24.5 million and had a significant positive effect on cash flows from
    operating activities, reflecting lower levels of inventory ($15.2
    million), unbilled revenues ($7.6 million), prepaid taxes ($4.9 million),
    miscellaneous current assets ($1.5 million) coupled with higher levels of
    accounts payable and accrued income taxes of $20.7 million and $13.3
    million, respectively  These were offset, in part, by a higher level of
    accounts receivable ($37.6 million).

         Construction expenditures for the first three months of 1994 were
    approximately $8.7 million, including an allowance for funds used during
    construction (AFUDC) and nuclear fuel.  Construction expenditures for the
    period, together with the preferred and common dividend requirements of
    the System ($8.1 million), were funded entirely with internally generated
    funds.  In addition to satisfying these capital requirements, the
    reduction in short-term borrowings of $52.5 million was accomplished with
    internal funds generated from higher unit sales (due to the extreme cold
    weather) experienced by both the electric and gas divisions during the
    first quarter of this year.

         Results of Operations

         The following is a discussion of certain significant factors which
    have affected operating revenues, expenses and net income during the
    periods included in the accompanying condensed statements of income.  This
    discussion should be read in conjunction with the Notes to Condensed
    Financial Statements appearing elsewhere in this report.

         Electric Revenues, Fuel and Purchased Power Costs

         For the first three months of 1994, electric operating revenues
  increased approximately $20.2 million or 13.4% due primarily to higher fuel
  and purchased power costs, new retail rates for Cambridge which became
  effective June 1, 1993 and a 2.1% increase in retail electric unit sales.

         Fuel and purchased power costs rose $19 million or 22.9% and
  reflects the increase in retail unit sales and the higher cost of fuel oil
  at Canal's generating facility, which is the major supplier of electricity
  to the system.  The cost of oil at Canal for the three-month period ended
  March 31, 1994 averaged 2.7 cents per KWH compared to 2.3 cents per KWH for
  the same period in 1993.  Fuel and purchased power costs averaged 4.3 cents
  per KWH compared to 3.8 cents per KWH for the same period in 1993 and
  reflect the impact of Commonwealth Electric's contractual obligations to
  purchase higher-cost power contracted for in the 1980s when its customer
  base grew dramatically and forecasts predicted continued growth.  The
  contracts, which are typically long-term power purchases from certain gas-
  fired independent power producing facilities, will continue to drive costs
  up as additional capacity comes on line.  Commonwealth Electric is
  currently involved in the renegotiation of several existing contracts which
  include price restructuring, contract buy-outs and/or generating unit
  shutdowns that could also reduce its cost of power.

         The 2.1% increase in retail electric unit sales was due primarily to
  higher unit sales in the residential and commercial sectors and reflects
  the colder than normal weather conditions experienced in our service
  territory during the first quarter.  The 18.3% increase in wholesale sales
  had little, if any, impact on net income.

         Gas Revenues and Cost of Gas Sold

         For the first three months of 1994, gas operating revenues increased
  $14.7 million or 12.2% due primarily to an increase in the cost of gas
  sold, higher firm unit sales and a higher level of conservation and load
  management costs ($974,000).  During the current three-month period, the
  average cost of gas increased to $3.72 per MMBTU from $3.31 per MMBTU for
  the same period of 1993 due, in part, to the billing of transition costs
  associated with the implementation of FERC Order No. 636.  During the
  current three-month reporting period, firm gas unit sales increased 5.6% as
  each customer segment showed improvement due to the colder than normal
  winter.

         Other Operating Expenses

         For the first three months of 1994, other operation and maintenance
  decreased $1.6 million or 2.5% due primarily to cost savings of
  approximately $2 million that resulted from a second quarter 1993 work
  force reduction offset, in part, by a higher level of current and amortized
  conservation and load management costs incurred primarily at Commonwealth
  Gas ($1.1 million).  Other factors contributing to the overall decline
  include a decrease in insurance and employee benefit costs ($485,000) and a
  lower provision for bad debts due to improved collections ($115,000).
  Despite a higher level of depreciable plant for the current three-month
  period, depreciation expense decreased 2% due to an adjustment in the
  second quarter of 1993 to Canal's accrual rate to reflect an extension of
  the depreciation recovery period for Unit 1 from 1996 to 2002.  Local
  property and other taxes increased 2.2% due primarily to higher tax rates
  and assessments.  A higher level of pretax income and, to a lesser extent,
  an increase in the federal tax rate to 35% contributed to the $3.3 million
  or 22.6% increase in federal and state income taxes.

         Other Income and Interest Charges

         For the first quarter of 1994, other income increased 35.3% due
  primarily to interest income related to a Massachusetts sales tax abatement
  ($159,000) and the absence in 1994 of a loss (recorded in January 1993) in
  connection with the system's equity investment in Yankee Atomic Electric
  Company ($74,000).  The impact of these items was offset, in part, by
  decreases in non-operating rents ($88,000) and accretion relating to the
  abandonment of Seabrook Unit 2 ($37,000).

         Total interest charges for the current quarter increased 5.2% due
  primarily to a higher level of long-term debt reflecting the new debt
  issued by Commonwealth Electric, Commonwealth Gas and Hopkinton LNG Corp.
  during 1993 and the interest to be refunded to the system's retail
  customers in connection with the aforementioned sales tax abatement.  The
  impact of these items was offset, somewhat, by the decline in short-term
  interest costs reflecting a lower average level of short-term borrowings.

  Environmental Matters

         Commonwealth Gas is participating in the assessment of a number of
  former manufactured gas plant sites to determine if and to what extent such
                                    PAGE 13

              COMMONWEALTH ENERGY SYSTEM AND SUBSIDIARY COMPANIES

  sites have been contaminated and whether Commonwealth Gas may be
  responsible for remedial actions.

         The costs associated with the clean-up of these sites are
  recoverable in rates through the cost of gas adjustment clause pursuant to
  a 1990 DPU order that provides for recovery of these expenditures over a
  seven-year amortization period without carrying costs.  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 various activities to be undertaken at these sites. 
  Commonwealth Gas has also recorded a regulatory asset in anticipation of
  recovery of these costs in rates.  Commonwealth Gas is unable to predict
  the total cost to ultimately resolve these matters due to significant
  uncertainty as to the actual site condition 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 with costs which
  may not be recoverable in rates and have recorded an estimated liability
  (and a charge to operations) of $560,000 in total to cover the costs
  associated with assessment and remediation activities.  These estimates
  will be adjusted as further investigation and assignment of responsibility
  occurs.  As noted above, the system is unable to predict at this time the
  ultimate cost to resolve these matters due to the uncertainties inherent in
  the site investigation and remediation process.

  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 that Cambridge and Commonwealth Electric
  pay a demand charge for their capacity entitlement in each unit and an
  energy charge to cover the cost of fuel.  Cambridge and Commonwealth
  Electric collect a portion of their capacity-related purchased power costs
  associated with certain long-term power arrangements through their base
  rates.  The recovery mechanism for these costs uses a per KWH factor which
  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 and Commonwealth Electric experience a revenue excess or short-
  fall.  This recovery mechanism had a positive impact on net income of
  $417,000 for the current quarter compared to a net loss of $581,000 for the
  first quarter of 1993.  All other capacity and energy-related purchased
  power costs are recovered through their respective Fuel Charge.

  Power Agreement Cancelled

         On May 2, 1994, Cambridge and Commonwealth Electric gave notice of
  termination of power purchase agreements with Eastern Energy Corp.
  (Eastern), the developer of a proposed 300 MW coal-fired plant in New
  Bedford, Massachusetts.  In June 1989, in order to meet rising energy
                                    PAGE 14

              COMMONWEALTH ENERGY SYSTEM AND SUBSIDIARY COMPANIES

  requirements, Cambridge and Commonwealth Electric agreed to buy 27% (33 MW
  and 50 MW, respectively) of the power to be produced by the proposed plant,
  originally scheduled to begin operation in January 1992.  That date and
  later revised scheduled operating dates have not been achieved, and the
  proposed plant has still not received the necessary permits.  Efforts to
  reshape the Eastern power purchase agreements to provide a satisfactory
  arrangement were unsuccessful.  The companies' actions are based on
  Eastern's failure to meet its contractual obligations.  Cambridge and
  Commonwealth Electric are unable to predict whether or not Eastern will
  contest their termination of these agreements.

  Rate Stabilization Plan

         Commonwealth Electric implemented a Fuel Charge (FC) rate settlement
  on April 1, 1994 that will stabilize its quarterly FC rate during the years
  1994 through 1996 at 6.5 cents per KWH and between 6.5 cents and 6.7 cents
  per KWH during 1997.  This rate stabilization results from 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
  stabilized FC rate could save customers between 1.75% and 5% on their
  annual electric bills from 1994 through 1997.  Deferred costs will be set
  up as a regulatory asset to be recovered, with carrying charges, over the
  subsequent six-year period beginning in 1998 under a recovery schedule to
  be approved by the DPU.  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 cost deferral of
  $16 million which is the amount Commonwealth Electric anticipates will be
  deferred in 1994.

         The rate stabilization mechanism is part of a long-term plan to con-
  trol Commonwealth Electric retail rates.  This plan will help to eliminate
  the disincentive for economic development resulting from a volatile and
  unpredictable FC rate.  The stabilized FC rate will enable current and
  prospective customers to 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.

         The settlement results in Commonwealth Electric billing its
  customers a significantly lower rate than would have been in effect on
  April 1, 1994 had the DPU not approved the proposal.  Commonwealth
  Electric's customers would have been billed for increased costs that
  resulted from certain higher-priced, long-term contract obligations. 
  Commonwealth Electric is currently involved in contract renegotiations, as
  mentioned previously in this discussion.
