                    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 1994 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.  Similarly, the
  regulatory liabilities established by the system are required to be refunded
  to customers over time.  In March 1995, the Financial Accounting Standards
  Board issued Statement of Financial Accounting Standards No. 121, "Account-
  ing for the Impairment of Long-Lived Assets and for Long-Lived Assets to be
  Disposed Of" (SFAS 121).  SFAS 121 imposes stricter criteria for regulatory
  assets by requiring that such assets be probable of future recovery at each
  balance sheet date.  Based on the current regulatory framework, the system
  accounts for the economic effects of regulation in accordance with the
  provisions of SFAS No. 71, "Accounting for the Effects of Certain Types of
  Regulation" and does not expect that the adoption of SFAS 121, which the
  system will adopt on January 1, 1996, will have a material impact on its
  financial position or results of operations.  However, this conclusion may
  change in the future as changes are made in the current regulatory framework
  or as competitive factors influence wholesale and retail pricing in this
  industry.  The principal regulatory assets included in deferred charges at
  September 30, 1995 and December 31, 1994 were as follows:

                                                         1995         1994

              COMMONWEALTH ENERGY SYSTEM AND SUBSIDIARY COMPANIES

      The regulatory liabilities, reflected in the accompanying balance sheets
  and principally related to deferred income taxes, were $24.4 million and
  $17.3 million at September 30, 1995 and December 31, 1994, respectively.

      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 September 30,
  1995 and 1994, 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 conform
  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 $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.

      (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 decommissioning fund to cover post opera-
  tional decommissioning costs.  The estimated cost to decommission the plant
  is $394 million.  Canal's share of this liability (approximately $13.6
  million), less its share of the market value of the decommissioning trust
  (approximately $1.4 million), is approximately $12.5 million.

          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 September
  30, 1995, Cambridge Electric Light Company's (Cambridge Electric) and
  Commonwealth Electric Company's (Commonwealth Electric) respective 2% and
  2.5% investment in Yankee Atomic was approximately $1.1 million.  The most
  recent cost estimate to permanently shut down the plant is approximately
  $350 million.  The companies' share of this liability is $15.8 million and
  is currently reflected in the accompanying consolidated balance sheets as a
  liability and corresponding regulatory asset.
<PAGE 8>

              COMMONWEALTH ENERGY SYSTEM AND SUBSIDIARY COMPANIES

          Other Nuclear Plants

      Cambridge Electric also has equity ownership interests ranging from 2.5%
  to 4.5% in three operating nuclear generating facilities located in New
  England with contract expiration dates ranging from 2007 to 2012.  Cambridge
  Electric 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 plants at the end of their estimated service
  lives.  Cambridge Electric's estimated total decommissioning cost and
  associated market value share of decommissioning trust assets for these
  units is approximately $36 million and $13.3 million, respectively.

      (c) FERC Order No. 636

      In May 1995, the DPU allowed Commonwealth Gas to accelerate recovery of
  its FERC Order No. 636 transition costs that were incurred to date.  These
  costs had been deferred and accumulated as a regulatory asset and were being
  recovered through the cost of gas adjustment (CGA) over a four-year period
  that began in November 1993.  The costs are now being recovered through the
  CGA over a one-year period that began May 1, 1995.  The accelerated recovery
  period was permitted by the DPU due to the minimal impact on customers'
  bills.  At September 30, 1995, a regulatory asset totaling $6.6 million was
  reflected in deferred charges.  In addition, a related liability of $6.6
  million was included in deferred credits.  Any further transition costs will
  be recovered by Commonwealth Gas through the CGA as incurred.

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.  Arrangements for bank
  lines of credit totaled $90 million in committed lines and $75 million in
  uncommitted lines at September 30, 1995, at which time approximately    
  $142 million was available to the system.  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 current nine-month period, cash flows from operating activities
  amounted to approximately $105.2 million and reflect net income of $34.5
  million and noncash items such as depreciation ($35.8 million) and amort-
  ization ($9.5 million).  The change in working capital since December 31,
  1994, exclusive of changes in cash ($4.1 million) and interim financing
  ($22.2 million), amounted to $41.1 million and had a significant positive
  impact on cash flows from operating activities, reflecting lower levels of
  unbilled revenues ($21.8 million), accounts receivable ($22.2 million) and
  inventories ($3 million) and a higher level of accrued taxes ($9.5 million)
  offset, in part, by an increase in prepaid taxes and other assets ($5.8
  million) and a decline in accounts payable ($10.8 million).  In addition,
  the current nine-month period reflects $25.5 million relating to
  Commonwealth Electric's power contract buy-out with an independent power
  producer (IPP).  This amount was paid in April 1995 and is being recovered
  with carrying charges over a seven-year period that began in April 1995.

      Construction expenditures for the current nine-month period were
  approximately $57 million, including an allowance for funds used during
  construction and nuclear fuel.  Construction expenditures, preferred and
  common dividend requirements of the System ($24.8 million), the payment of
  short-term borrowings ($22.2 million) and the refunding of long-term debt
  ($10 million) were funded almost entirely with internally generated funds.

  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 Operating Revenues, Fuel and Purchased Power Costs

      For the current quarter and nine-month period, electric operating
  revenues decreased approximately $11.5 million (6.6%) and $41.6 million
  (8.4%), respectively, as compared to the same periods in 1994 due mainly to
  lower unit sales, primarily wholesale sales.  However, fluctuations in the
  level of wholesale sales have little, if any, impact on net income.  In
  addition, during the current nine-month period retail unit sales to
  residential customers declined 2.9% reflecting the extremely mild weather
  conditions during the first quarter of 1995 compared to the record cold
  experienced during the same period in 1994.  Somewhat offsetting the decline
  in residential sales in the nine-month period were higher unit sales to
  commercial customers (1.6%).  Retail unit sales during the current quarter
  were virtually unchanged compared to the same period in 1994.

      The lower level of fuel and purchased power costs ($9.7 million and
  $29.7 million) during the current three and nine-month periods was due
  primarily to lower fuel oil costs at Canal Unit 1 reflecting a combination
  of scheduled maintenance and other repairs to the Unit 1 turbine which kept
  the unit out of service until August 1995.  Also contributing to this
  decrease was the reduced availability of Canal Unit 2 and the successful
  renegotiation of a contract with an IPP completed earlier this year that
  defers purchases for a six-year period.  Also, in January 1995, Commonwealth
  Electric terminated a long-term power contract with another IPP through a
  buy-out arrangement which has reduced power costs and will provide greater
  savings in the future.  Slightly offsetting these reductions was greater

  generation from Seabrook and an increase in power purchases from several
  smaller power producers.

      Commonwealth Electric and Cambridge Electric have received approval from
  the DPU to recover in revenues certain current costs associated with
  conservation and load management (C&LM) programs through the operation of a
  Conservation Charge decimal on a dollar-for-dollar basis.  To the extent
  that these expenses increase or decrease from period to period based on
  customer participation, a corresponding change will occur in revenues.  For
  the current nine-month period, this item declined $1.8 million and $755,000
  for Commonwealth Electric and Cambridge Electric, respectively.

      Historically, revenues collected through base rates have been designed
  to reimburse Commonwealth Electric and Cambridge Electric for all costs of
  operation other than fuel, the energy portion of purchased power, trans-
  mission and C&LM costs, and provide a fair return on capital invested in the
  business.  However, as a result of a DPU-mandated recovery mechanism for
  capacity-related costs associated with certain long-term purchased power
  contracts, Commonwealth Electric and Cambridge Electric experience a revenue
  excess or shortfall when unit sales and/or the costs recoverable in base
  rates vary from test-period levels.  This issue, which has had a significant
  impact on net income, was addressed in settlement agreements approved by the
  DPU in May 1995.  (Refer to the "Rate Settlement Agreements" section for
  additional details.)  During the current three and nine-month periods,
  approximately $2.2 million and $569,000 of revenues in excess of associated
  capacity-related costs were deferred pursuant to the settlement agreements. 
  The current nine-month period also includes $969,000 of capacity-related
  costs not recovered in revenues that were incurred prior to the implemen-
  tation of the settlements.  For the same periods in 1994, revenues included
  approximately $1.9 million and $1.1 million in excess of associated
  capacity-related costs due to the recovery mechanism.  As a result of this
  issue, net income was approximately $1.2 million lower in the current
  quarter and $1.3 million lower in the current nine-month period.

  Gas Operating Revenues and Cost of Gas Sold

      Gas operating revenues decreased $28.1 million or 11.5% for the current
  nine-month period due mainly to a $22.6 million reduction in the cost of gas
  sold that reflected a lower level of firm unit sales.  This decrease was
  also attributed to lower interruptible unit sales offset, in part, by higher
  transportation volume and off-system and quasi-firm sales that began in
  1994.  During the current quarter, gas operating revenues decreased by $4.9
  million or 10.5% due to a $5.3 million decrease in the cost of gas sold and
  lower interruptible unit sales partially offset by higher transportation
  volume, off-system and quasi-firm sales and an increase in firm unit sales.

      Firm unit sales decreased 8.4% during the current nine-month period as
  sales to all customer classes declined due to mild weather experienced
  throughout the region during the first quarter compared to a colder than
  normal first quarter last year.  Heating degree days for the current nine
  months totaled 4,055 compared to 4,449 for the same period in 1994, a
  decrease of 8.9%.  Firm unit sales were 5.6% higher during the current
  quarter as heating degree days were 249 compared to 207 for the same period
  in 1994.  Although interruptible sales decreased significantly during both

              COMMONWEALTH ENERGY SYSTEM AND SUBSIDIARY COMPANIES

  current periods, fluctuations in these sales have little, if any, impact on
  net income.  The contribution of off-system and quasi-firm sales to total
  sales had no impact on net income.  One-half of the margin realized on these
  sales was used to reduce the cost of gas to firm customers.  The remaining
  half is being deferred pending DPU approval of margin sharing proposals that
  are expected to be filed later this year for quasi-firm sales and early next
  year for off-system sales.

  Other Operating Expenses

      Other operation and maintenance decreased by approximately 4% and 3%
  during the current quarter and first nine months of 1995, respectively, due
  primarily to lower C&LM costs ($1.5 million and $2.8 million) and a decline
  in the provision for bad debts reflecting improved collection experience
  ($207,000 and $762,000) offset, in part, by higher labor costs ($630,000 and 
  $2.7 million) and employee benefit costs ($511,000 and $1.7 million).  The
  decrease during the current nine-month period was also offset by higher
  maintenance costs ($1.2 million) reflecting scheduled maintenance and other
  repairs to the Canal Unit 1 turbine.  The higher level of benefit costs
  reflects the full recognition of expenses relating to postretirement
  benefits other than pensions and the amortization of previously deferred
  postretirement benefits costs.  (Refer to the "Rate Settlement Agreements"
  section for additional details.)

      Depreciation expense increased 11.1% and 8.6% in the current three and
  nine-month periods due mainly to a higher level of depreciable property,
  plant and equipment.  The increase in the nine-month period also reflects an
  adjustment to depreciation rates related to Canal Unit 1 during the second
  quarter.  Local property and other taxes increased 2.4% during the current
  nine-month period due mainly to higher rates and assessments offset, in
  part, by a $201,000 adjustment to the 1995 property tax estimate made by
  Commonwealth Electric.  The decrease in local property and other taxes
  during the current three-month period reflects the aforementioned estimate
  adjustment offset, in part, by higher rates and assessments.  Federal and
  state income taxes decreased $10.3 million or 44.5% during the current nine-
  month period due to a significantly lower level of pretax income and a tax
  adjustment in conjunction with the aforementioned settlement agreements with
  the DPU.  The increase in federal and state income taxes during the current
  quarter reflects the level of pretax income.

  Other Income and Interest Charges

      The increase in other income for the current nine-month period was due
  primarily to the partial reversal of a reserve related to certain costs
  associated with Commonwealth Electric's energy conservation program, the
  recovery of which was subsequently approved by the DPU.  The increase in the
  current quarter was due to the absence of the reserve recorded in the same
  quarter in 1994.

      Total interest charges for the current nine-month period increased 3.2%
  due to an increase in interest on deferred gas costs ($1.6 million) and
  higher interest rates on a greater level of short-term borrowings offset, in
  part, by an increase in the debt component of allowance for funds used
  during construction ($622,000).

  Regulatory Matters

      Electric Industry Restructuring

      On August 16, 1995, the DPU issued an order calling for the restruc-
  turing of the electric utility industry in Massachusetts.  The stated
  purpose of the restructuring effort is to allow customers more flexibility
  in choosing their electric service provider and to develop an efficient
  industry structure and regulatory framework that minimizes long-term costs
  to consumers while maintaining the safety and reliability of electric
  services with minimum impact on the environment.  The electric utility
  industry will ultimately be functionally separated into three segments to
  help meet this objective: generation, distribution and transmission.  A
  coalition of state agencies, businesses, environmental groups and utility
  companies, including Commonwealth Electric and Cambridge Electric, worked
  together sharing ideas and opinions and proposed eighteen principles for a
  restructured electric utility industry. The DPU agreed with several of the
  coalition's suggestions and, in its order, identified the following seven
  principles:

      (1)  provide the broadest possible customer choice;

      (2)  provide all customers with an opportunity to share in the benefits
           of increased competition;

      (3)  ensure full and fair competition in power generation markets;

      (4)  functionally separate generation, transmission and distribution
           services;

      (5)  ensure electric service to all customers, including low-income
           customers;

      (6)  support and further the goals of environmental regulation; and

      (7)  provide incentives for better utility performance.

      Also, five principles to guide the transition from a regulated to a
  competitive industry structure were established in the order. These
  principles are:

      (1)  honor existing commitments;

      (2)  separate component costs of electricity on customer bills;

      (3)  seek to provide near-term rate relief;

      (4)  maintain conservation programs; and

      (5)  ensure that the transition is orderly and expeditious while
           minimizing customer confusion.

              COMMONWEALTH ENERGY SYSTEM AND SUBSIDIARY COMPANIES

      In addition, the order cites that utilities should have a reasonable
  opportunity to recover stranded costs associated with commitments previously
  incurred to provide reliable electric service.

      All utilities are required to submit proposals detailing how they plan
  to move into a competitive market structure.  Commonwealth Electric's and
  Cambridge Electric's proposal is due by August 16, 1996.

      Stranded Investment Charge Approved

      On September 29, 1995, the DPU issued a ruling largely approving four
  rate tariffs, including a Customer Transition Charge (CTC), that were filed
  by Cambridge Electric on March 15, 1995.  The CTC will protect remaining
  customers from paying certain costs, often referred to as stranded
  investment costs, that were incurred to provide electric service to large
  customers that meet certain usage requirements and remain within Cambridge
  Electric's service area but decide to purchase their power from another
  source or generate their own power.  These costs include long-term power
  contracts entered into to meet projected energy requirements, investments in
  substations, underground and overhead lines and current and future
  decommissioning costs associated with nuclear plants.  This ruling is
  believed to be the first retail stranded cost charge approved nationally and
  follows the aforementioned restructuring order which endorsed, in principle,
  the recovery of stranded investment costs.

      Through the CTC, Cambridge Electric will initially recover 75% of net
  stranded investment costs as calculated by Cambridge Electric in its
  proposal.  Cambridge Electric's other rates include the Supplemental Service
  Rate, the Standby Service Rate and the Maintenance Service Rate each of
  which were approved with only minor changes.  Cambridge Electric is
  encouraged by the DPU's position on recovery of stranded investment costs
  and expects to address recovery of the remaining 25% in its restructuring
  filing.

      Rate Settlement Agreements

      In May 1995, the DPU approved settlement proposals sponsored jointly by
  Commonwealth Electric, Cambridge Electric and the Attorney General of
  Massachusetts which resolved issues related to cost of service, rates,
  accounting matters and generating unit performance reviews. Commonwealth
  Electric's agreement:

      (1)  implements a $2.7 million annual retail base rate decrease
           effective May 1, 1995 including its share of excess deferred tax
           reserves related to Seabrook Unit No. 1 refunded in May 1995 to
           Commonwealth Electric by Canal.  Further, the settlement imposes a
           moratorium on retail rate filings until October 1998;

      (2)  limits Commonwealth Electric's return on equity as defined in the
           settlement, for the period through December 31, 1997;

      (3)  terminates several 1987-1994 generating unit performance review
           proceedings pending before the DPU;
<PAGE 16>

              COMMONWEALTH ENERGY SYSTEM AND SUBSIDIARY COMPANIES

      (4)  amends Commonwealth Electric's current fuel charge stabilization
           mechanism to include deferral (without carrying charges) of certain
           long-term purchased power and transmission capacity costs within
           the original limits established for the fuel charge stabilization
           deferral ($16 million in any given calendar year and $40 million
           over the life of the mechanism);

      (5)  requires Commonwealth Electric to fully expense costs relating to
           postretirement benefits other than pensions in accordance with
           Statement of Financial Accounting Standards No. 106 and amortize
           the deferred balance of $8.6 million over a ten-year period;

      (6)  provides eligible Economic Development Rate customers with a
           discount of up to 30% but also requires these customers to provide
           Commonwealth Electric with a five-year notice if they intend to
           self-generate or acquire electricity from another provider; and

      (7)  prohibits Commonwealth Electric from seeking recovery of the costs
           incurred in realizing cost savings through a 1993 work force
           reduction and restructuring, totaling approximately $3 million.

  Cambridge Electric's agreement:

      (1)  implements a $1.5 million refund to Cambridge Electric's customers
           through the Fuel Charge during the third and fourth quarters of
           1995 including its share of excess deferred tax reserves related to
           Seabrook Unit 1 refunded in May 1995 to Cambridge Electric by
           Canal;

      (2)  allows Cambridge Electric to defer certain long-term purchased
           power and transmission capacity costs in excess of the amount of
           such capacity costs currently included in Cambridge Electric's base
           rates up to an annual amount of $2 million for recovery in its next
           general retail base rate case;

      (3)  prohibits Cambridge Electric from seeking recovery of costs it
           incurred in obtaining cost savings through a work force reduction
           and restructuring, totaling approximately $400,000; and

      (4)  includes the DPU's withdrawal of all related requests, appeals,
           motions or other issues raised by parties regarding certain
           generating unit performance reviews.

      The system's management is encouraged by the support provided through
  the Office of the Attorney General and believes that these settlements will
  eliminate the need for potentially costly litigation and regulatory
  proceedings and, by moderating rate impacts and enabling the system to
  remain competitive in a changing environment, the settlements are in the
  best interest of the system and its customers.

  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.  Commonwealth Gas and other system subsidiaries are also involved
  in certain other known or potentially contaminated sites where the
  associated costs may not be recoverable in rates.  There were no significant
  new developments that occurred during the current nine-month period.  For
  further information on these matters, refer to the System's 1994 Annual
  Report on Form 10-K.
