Item 1. Business general l Commonwealth Energy System, a Massachusetts trust, is an unin-corporated business organization with -ransferable shares. It is organized under a Declaration vi Trust dated December 31, 1976, as amended, pursuant to the laws of Massachusetts. It is an exempt public utility holding company under the provisions of the Public l Utility Holding Company Act of 1935, holding all of the stock of four operating public utility companies. Commonwealth Energy System, the parent company, is referred to in this report as the " System" and i together with its subsidiaries is sometimes collectively referred to as "the system." l l The operating utility subsidiaries of the Syctem are engaged in l the generation, transmission and distribution of electricity and the i distribution of natural gas, all within Massachusetts. These subsid-l laries are: Eectric gas a Cambridge 41octric Light Company Commonwealth Gas Company l Canal Eleutric Company Commonwealth Electric Company In addition to the utility companies, the System also owns all of the stock of a steam distribution company (COM/ Energy Steam Company), i five real estate trusts and a liquefied natural cas (LNG) and vapor- 1 ization facility (Hopkinton LNG Corp.). Subsidiaries of the System have common executive and financial management and receive technical l assistance as well as financial, data processing, accounting, legal and other services from a wholly-owned services company subsidiary (COM/ Energy Services Company). The five real estate subsidiaries are: Darvel Realty Trust, l which.is a joint-owner of the Riverfront Office Park complex in Cam-bridge; COM/ Energy Acushnet Rcalty, which leases land to Hopkinton LNG Corp.; COM/ Energy Research Park Realty, which was organized to develop

a research building in Cambridge; COM/ Energy Cambridge Realty, which was organized to hold various properties; and COM/ Energy Freetown

' Realty (Freetown), which was organized in 1986 to purchase and develop 596 acres of land in Freetown, Massachusetts. Freetown's preliminary plans called for the development of an energy park, the first phase of which included the construction of a 440 megawatt (MW) generating unit, through the joint efforts of Freetown and Texaco Syngas, Inc. ar" 3 subsidiary of General Electric Company (the co-developers), l Effective November 30, 1991, the co-developers notified Freetown of their intent not to continue with the project due to poor economic conditions and significant declines in regional load forecasts which COMMONWEALTH EMERGY SYSTEM , FORM 10-K DECEMBER 31, 1991 Item JLt Business (Continued) General (Continued) pushed the need far power out to the late 1990s. Subsequent efforts by the System to generate interest in alternative uses of the site were hampered by continuing difficulties in the regional economy, particularly in the real estate market. On January 23, 1992, the System announced its decision to write-dcwn its investment in the Freetown project. This action resulted in the recognition of a one-time (net of tax) charge of $14.8 million. For additional informa-tion, refer to Note 11(a) of the Notes to Consolidated Financial Statements filed under Item 8 of this report. Each of the operating utility subcidiaries previously listed ~ serves retail customers except for Canal Electric Company (Canal) which operates an electric generating station located at the eastern and of the Cape Cod Canal in Sandwich, Massachusetts. The station consists of two oil-fired steam electric generating units: Canal Unit 1, with a rated capacity of 569 MW, wholly-owned by Canal; and Canal Unit 2, with a rated capacity of 580 MW, jointly-owned by Canal and Montaup Electric Company (Montaup) Canal Unit 2 is operated under an agreemen(an unaffiliated t with Montaup company). which provides for the equal sharing of output, fixed charges and operating expenses. Electric service is furnished by Cambridge Electric Light Company (Cambridge Electric) and Commonwealth Electric Company (Commonwealth Electric)ont retail to approximately 304,000 year-round customers in 41 communities in eastern Massachusetts covering 1,112 square miles and having an aggregate population of 645,000. The system also serves approximately 49,000 seasonal retail customers. The territory served includes the communities of Cambridge, New Bedford and Plymouth and the geographic area comprising Cape Cod and Martha's vinoyard. Cam-bridge Electric also sells power at wholesale to the Town of Belmont, Massachusetts, Natural gas is distributed by Commonwealth Gas to approximately 228,000 customers in 49 communities in central and eastern-Massachu-setts covering 1,067 square miles and having an aggregate population of 1,128,000. Twelve of these communities are also served by system companies with electricity. Some of the larger communities served by Commonwealth Gas include Cambridge, Somerville, New Bedford, Plymouth, Worcester, Framingham, Dedham and the Hyde Park area of Boston. The population in the system's electric service area increased by 15.2% while the population in the gas service area increased by 12% since the last federal census was taken in 1980. Steam, which is produced by Cambridge Electric in connection with the generation of electricity, is purchased by COM/ Energy Steam and, together with its own production, is distributed to 19 customers in Cambridge and 1 customer (Massachusetts General Hocpital) in Boston. Steam is used for space heating and other purposes. A major new customer, New England Confectionary Company (Necco), is scheduled to

COMMONWEALTH ENERGY SYSTEM FORM 10-K- DECEKBER 31. 1991 Item 1. Business (Continued) General (Continued) begin receiving steam service in June 1992. Necco will become the fourth largest customer of COM/ Energy Steam. Industry in the territories served is highly diversified. The larger industrial customers include high-technology firms and manu-facturers of such products as photographic equipment and supplies, rubber products, textiles, wire and other lastening devices, abrasives and grinding wheels, candy, copper and alloys, and chemicals. Among customers served are several major educational institutions, including Harvard University and the Massachusetts Institute of Technology. Electric Power Supply System companies own generating facilities with a capability totaling 1,078.4 MW. Included in this amount is 572 MW provided by Canal Unit 1, of which three-quarters (429 MW) is sold to neighboring utilities under long-term contracts, and 292 MW provided by Canal Unit

2. In 1991, Canal executed an exchange transaction with Central Vermont Public Service Corporation (CVPS) whereby 50 MW of Canal Unit 2 was exchanged for 25 1N each of CVPS's entitlement in the Vennont Yankee nuclear power plant and the Merrimack 2 coal-fired unit through October 1995 in order to reduce the system's reliance on oil. Another 214.4 MW is provided by various smaller system units. Of the 649.4 MW available to the system, 66.4 MW is used principally for peaking purposes. Seabrook 1 provides 40.5 MW of capability to the system and Central Maine Power Company's Wyman Unit 4, an oil-fired facility in which the system has a 1.4% joint-ownership interest, provides 8.9 MW.

In addition, i.te system has available 77.7 MW from four (4) " nuclear units in which the distribution companies have ownership interests.

COMMONWEALTH ENERGY SYSTEM . FORM 10-K DECEMBER 31, 1991 Item 1. Business (Continued) Electric Power Supolv (Continued) On February 26, 1992, the Board of Directors of the Yankee Atomic unit decided to permanently close the plant and, in time, decommission the facility. For additional information, refer to Note 4(f) of the Notes report. to Consolidated Financial Statements filed under Item 8 of this To satisfy demand requirements and provide required reserve capacity, the system supplements its generating capacity by purchasing power on a long and short-term basis through capacity entitlements under power contracts with other New England and Canadian utilities and with Qualifying Facilities through a competitive bidding process ' which is regulated by the Mr.ssachusetts Department of Public Utilities and also with other non-utility generators. Long-term purchase arrangements include a 73.7 MW entitlement from a nuclear unit in Plymouth, Massachusetts (Pilgrim) under a life-of-the-unit contract with Boston Edison Company. In addition, through Canal's equity ownership in Hydro-Quebec Phase II, the system has an entitlement of 67.9 MW. Long-term purchase arrangements are in place with the following natural gas-fired cogenerating units in Massachu-setts: 26.8 MW from the Consolidated Powcr Company, 37.2 MW from Pep-perell Power Associates and 53 MW from Northeast Energy Associates. Additionally, the system receives 46.2 MW from the SEMASS waste-to-energy plant in Rochester, Massachusetts, and has entitlements totaling 24.7 MW through contracts with five (5) hydroelectric sup-pliers, including 20 MW from Boott Hydropower, Inc., in Lowell, Massachusetts. The system anticipates providing for future peak load plus reserve requirements through existing and planned system generation, including purchasing excess capacity from neighboring utilities and/or non-utility generators. L Cambridge Electric, Canal and Commonwealth Electric, together with other electric utility companies in the New England area, are members of the New England Power Pool (NEPOOL), which was formed in 1971 to provide for the joint planning and operation of electric systems throughout New England. NEPOOL operates a centralized dispatching facility to ensure reliability of service and to dispatch the most economically available generating units of the member companies to fulfill the region's energy requirement. This concept is accomplished by use of computers to monitor and forecast load requirements and provide for the economic dispatching of generation. NEPOOL, on behalf of its members entered into an Interconnection Agreement with Hydro-Quebec, a Canadian utility operating in the Province of Quebec. The agreement provided for construction of an interconnection (Phase I) between the electrical systems of New England and Quebec. These parties have also entered into an Energy

Contract and an Energy Banking Agreament; the former obligates Hydro-Quebec to offer NEPOOL participants up to 33 million MWH of surplus energy during an eleven-year term commencing September 1, 1986 and the latter provides for energy transfers between the two systems. The Phase I Interconnection began operation in October 1986. NEPOOL has also entered into Phase II agreements for an additional purchase from Hydro-Quebec of 7 million MWH per year for a twenty-five year period which began in late 1990. The System's electric subsidiaries are also members of the horth-east Power Coordinating Council (NPCC), an advisory organization which includes the major power systems in New England and New York plus the provinces of Ontario and New Brunswick in Canada. NPCC establishes criteria and standards for reliability and serves as a vehicle for co-ordinction in the planning and operation of these systems in enhancing reliability. The reserve requirements used by the NEPOOL participants in plan-ning future additions are determined by NEPOOL to meet the reliability criteria recommended by NPCC. The system estimates that, during the next ten years, reserve requirements so determined will be in the range of 23% to 29% of peak load. Power Supply Commitments and Support Acreements Cambridge Electric and Commonwealth Electric, through Canal, secure cost savings for their respective customers by planning for bulk power supply on a single system basis. The system's 3.52% interest in the Seabrook nuclear power plant is owned by Canal to provide for a portion of the capacity and energy needs of Cambridge Electric and Commonwealth Electric. Seabrook was originally designed to have two pressurized water reactors, each with a rated capacity of 1,150 MW. Seabrook I has been completed since mid-1986. The second reactor, however, was abandoned in 1984. Upon the plant's commercial operation in 1990, Canal began recovering 100% of its Seabrook 1 investment through power contracts with Cambridge Electric and Commonwealth Electric, subject to refund pending a full review of Canal's investment in the unit by the FERC. For additional information concerning Eeabrook 1, refer to Note 4(b) of Notes to Consolidated Financial Statements filed under Item 8 of this report. In response to solicitations made to NEPOOL members by Northeast Utilities (NU) Canal, on behalf of Commonwealth Electric and Cambridge Electric, agreed to purchase entitlements through short and long-term contracts in various selected generating units. The length of these separate agreements range up to a five-year period. COMMONWEALTH ENERGY SYSTEM FORM 10-K DECEMBER 31, 1991 Item 1. Business (Continued) " Power Supply Commitments and Suopost Acreements (Continued) The terms of the five-year agreement stipulate the purchase of 50 MW, on average, from NU annually from November 1989 through October 1994. Commonwealth Electric and Cambridge Electric are each appropriated a portion of the power received from NU based on need. These and other bulk electric power purchases are necessary in order to fulfill the system's NEPOOL obligation and to meet Commonwealth Electric and Cambridge Electric capacity requirements. Canal participated with other electric utilities in the construc-tion and operation of Hydro-Quebec Phase I transmission facilities in northeastern Vermont, which were completed in 1986 at a cost of - approximately $140 million. Upon commercial operation of Phase II and per the Phase I Support Agreements, Canal's share of Phase I was reduced to 3.7% to allow for greater participating interest of two other utilities. Canal has also entered into a support agreement for 3.8% of Hydro-Quebec Phase II facilities which were completed in November 1990 at a cost of $487 million. For additional information relating to Canal's interest in Hydro-Quebec Phases I and II, refer to Note 4(e) of Notes to Consolidated Financial Statements filed under Item 8 of this report. Price-Andercon Act The Price-Anderson Act (the Act) is a federal statute that in-cludes among its provisions a requirement for licensees of nuclear electric generating units to maintain financial protection to cover public liability claims resulting from a nuclear incident or precau-tionarr evacuation and a restriction on the maximum liability exposure resulting from any single nuclear incident. In 1988, Congress enacted a fifteen-year extension of the Act and increased the available insur- . ance and the maximum liability. The higher coverage is provided by existing private insurance and retrospective assessments for costs in excess of that covered by insurance, up to $66.2 million for each nuclear reactor which is licensed to operate with a maximum assessment of $10 million per incident within one calendar year. Based on the system's equity ownership in the corporations owning four nuclear generating facilities and its 3.52% ownership interest in Seabrook 1, the system's retrospective premium could be as high as $1.9 million yearly or a cumulative total of $12.6 million, exclusive of the effect of inflation indexing (at five-year intervals) and a 5% surcharge ($3.3 million) in the event that total public liability claims from a nuclear incident exceed the funds available to pay such claims.

FORM 10-K DECEMBER 31, 1991 Item 1. Business (Continued) l Electric Fuel Sucolv i l (a) Q M 1 Imported residual oil is the primary fuel used in the generation of power in system generating plants. Approximately 42% of the system's current energy requirements for retail sales are from oil 3 producing plants. ' Effective July 1, 1991, Canal executed a two-year contract with Coastal Oil New England, Inc. (Coasta.) for the purchase of reLidual fuel oil. .The contract provides for the delivery of a set percentage of Canal's fuel requirement, the balance to be met by spot purchases or by Coastal at the discretion of Canal. 1 L Energy Supply and Credit Corporation (ESCO) operates Canal's oil i terminal for the purchase, receipt and payment of oil under assignment t of Canal's supply contracts to ESCO (Massachusetts), Inc. Oil in the terminal's tanks is held in inventory by ESCO and delivered upon demand to Canal's tanks. Fuel oil storage facilities at the Canal site have a capacity of 1,199,000 barrels, representing 34 days of normal operation of the two units. During 1991, ESCO maintained an average daily inventory of 623,000 barrels of fuel oil which represents 18 days of normal oper-ation of the two units. This supply is maintained by tanker deliv-l eries approximately every ten to fifteen days. ! Reference is made to Item 7, " Management's Discussion and Analysis of Financial Condition and Results of Operations," for a discus.' ion of the cost of fuel oil. (b) Nuclear Fuel Sucolv and Disposal l Approximately 31% of the system's 1991 energy requirements for retail sales was generated by nuclear plants. The supply of fuel for nuclear generating plants generally involves the acquisition of uran-ium concentrate, its conversion to uranium hexafluoride, enrichment, fabrication of the nuclear fuel assemblies and disposition through reprocessing or storage of spent fuel. The contract and inventory information which follows for Seabrook 1 has been furnished to Canal by New Hampshire Yankee (NHY), the plant ) manager responsible for operation of the unit. With respect to uran-ium and converted uranium requirements, there is existing inventory for the second reload and 100% coverage for the third reload. Uranium requirements are 65% covered through 1996 and converted uranium re-quirements are up to 100% covered through 1999. The contract for l fabrication services is fully covered through 1998. With respect to enrichment services, Seabrook 1 has 100% coverage COMMONWEALTH ENERGY SYSTEM ' FORM 10-K PLCEMBER 31, 1991 Item 1. Business (Continued) (b) Nuclear Fuel Supoly and Disposal (Continued) for the second reload and 70% coverage for the third reload. During the 1995-2014 period, there is full coverage. There are no spent fuel reprocessing fa;ilities currently oper-ating in the United States. Instead, United States operating nuclear generating un ts are required to retain high level wastes and spent fuel on-site or make long-term arrangements for their storage. As required by the Nuclear Waste Policy Act of 1982 (the Act), as amen-ded, the joint-owners entered into a contract wJth the Department of i Energy for the transport and disposal of spent fuel and high level  ! radioactive waste at a national nuclear waste repository. Owners or generators of spent nuclear fuel ar its associated wastes are required to bear all of the costs for such transportation and disy.Ja1 through payment of a fee of approximately 1 mill /KWH based on net electric generation to the Nuclear Waste Fund. Under the Act, a temporary national repository for nuclear waste was anticipated to be in operation by 1998; however, a reassessment of the project's schedule I requires extending the completion date of the permanent f acility until at least 2010. Seabrook 1 is currently licensed for enough on-site storage to accommodate all spent fuel expected to be accumulated through the year 2010. Furthermore, NHY will be evaluating options for extending on-site spent fuel storage capacity beyond this time. , Gas sucolv General The system obtains its natural gas supplies under long-term con-acts with two pipeline companies, Tennessee Gas Pipeline Company (tennessee), a division of Tenneco, Inc., and Algonquin Gas Transmis-sion Company (Algonquin), a wholly-owned subsidiary of Texas Eastern Transmission Corporation. The principal Algonquin contra- , extend through 1996 and the Tennessee contract through the year i a0. These contracts provide for specified quantities of natural gas, which con-stitute the system's principal sources of supply to meet its require-ments for firm gas (i.e., gas sales which are not contractually su',- jact to interruption). The system also purchases gas on the spot market. In addition, LNG facilities, described below, are used to iquefy and store pi the heating season. peline Duringgas during 1991, allthe warmer of the months system's firmforgas use during requireGents were supplied by pipeline gas. Approximately 57% of these supplies were purchased on the spot market. In 1990, the system exercised its right to convert a portion of its firm sales contract with Algonquin to firm transportation. Effec-tive November 1, 1990, the system converted 17,285 MMBTU/ day out of its 87,207 MMBTU/ day contract. The gas will be purchased under long-term firm contracts (five to six years) from four separate suppliers and transportation will be provided by Texas Eastern and Algonquin on

Approxi-mately 87% of this gas is covered by three contracts that were approved by the CPU on January 11, 1991. These contracts allow for increased reliability and the ability to purchase gas at a cost lower than the prior firm sales arrangements with Algonquin. The remaining contract has been signed and submitted to the DPU for its review and approval. In 1991, the system converted a portion of its existing firm gas supply contract with Tennessee Gas Pipeline to firm transportation. The conversion became effective in September 1,1991 with a maximum daily quantity (MDQ) of 10,000 MKBTU representing approntmately 10% of the then existing sales MDQ of 56,826 MMBTU. The purchase contract associated with the conversion has been submitted to the DPU for its review and approval Commenwealth Gas began transporting gas in 1990 for end-users on its system. There are currently only three customers using this transportation service. Total end-user transportation accounted for only 299,760 MMBTU of throughput in 1991 which represented approxi-mately 0.7% of system throughput. Hookinton LNG eacility A portion of the system's gas requirements during the heating season are provided by Hopkinton LNG Corp. (Hopkinton), a wholly-owned subsidiary of the System. The facility consists of a liquefaction and vaporization plant and three above-ground cryogenic storage tanks having an aggregate capacity of 3 million MCF of natural gas. In addition, Hopkinton owns a satellite vaporization plant and two above-ground cryogenic storage tanks located in Acushnet, Massa-chusetts. These storage tanks have an aggregate capacity of 500,000 MCF of natural gas and are filled with LNG trucked from the tanks in Hopkinton. Commonwealth Gas Company has a contract for LNG service with Hopkinton extending through 1996, thereafter renewable year to year with notice of termination due five years in advance. Contract payments include a demand charge sufficient to cevar Hopkinton's fixed , charges and an operating charge which covers. liquefaction and vaporization expenses. Commonwealth Gas furnishes pipeline gas during the period April 15 to November 15 each year for liquefaction and storage. As the need arises, LNG is vaporized and placed in the distribution system of Commonwealth Gas.

Business (Continued) Hookinton LNG Facility (Continued) Based upot.- information presently available regarding projected growth in demano and estimates of availability of future supplies of pipeline gas, the System believes that its present sources of gas supply are adequate to meet existing load and allow for future growth in sales. { i Rates. Reculation and Locislation  ! Certain of the System's utility subsidiaries operate under the  ! jurisdiction of the DPU, which regulates retail rates, accounting,  ! issuance of securities and other matters. In addition, Cant. Electric and Cambridge Electric file their respective wholesale rates with the i Federal Energy Regulatory Commission (FERC) . (a) Wholesale Rate Proceedinos Cambridge Electric needs PERC approval to increase its wholesale rates to the Town of 40.mont, Massachusetts (Belmont), a " partial requirements

  • customer of Cambridge Electric since 1986. These rates include a fuel adjustment clause which reflects changes in costs of .

fuels and purchased power used to supply Belmont. On March 23, 1990, Cambridge Electric filed a request with the FERC to increase its wholesale rates to Belmont by $2,252,000 annually. The request was largely due to increased purchased power costs and major additions to plant-in-service since the last filing in 1985. cambridge Electric proposed rates, subsequently accepted by the FERw, which went into effect, subject to refund, on August 1, 1990. On September 19, 1990, Cambridge Electric and Belmont filed an uncontested Offer of Settle-ment which the FERC approved on December 6, 1990. This settlement resolved all issues with the exception of Seabrook 1 costs which are subject to change based upon the results of the FERC's final review of Canal's investment in-the unit. This settlement required Cambridge Electric te edjust its Belmont rate to reflect the final allocation of power purchased by Canal on behalf of Cambridge Electric and Common-wealth Electric. Osmbridge Electric made a refund to Belmont in August 1991 and filed the requisite compliance report with the FERC on September 16, 1991. A settlement agreement between Canal and Belmont addressing all Seabrook cost-of-service issues (except rate of return on common equity) was filed with the PERC on April 16, 1991 and subsequently approved by the FERC on November 13, 1991. This settlemont resulted in refunds to Cambridge Electric and Commonwealth Electric by Canal and further resulted in changes to Belmont's rate. In addition, this settlement changed the ef fective date of the Belmont Service Agreement f rom August 1, 1990 to June 30, 1990. The charges and refunds resulting from this mottlement were applied to Belmont's bill in January 1992. [ COMMONWEALTH ENERGY SYSTEM FORM 10-K DECEMDER 31, 1991 l Item 1.

To the extent that collections under the rate schedule do not match actual costs for that period, an appropriate adjustment is reflected in t:w calculation of l the decimal for the next subsequent calendar quarter. Amounts l recoverable under thest clauses are subject to review and approval by the DPU. Cambridge Electric collect: the capacity-related portion of its purchased power costs associated with certain long-term power arrangements through its base rates. The DPU ordered Commonwealth Electric, effective July 1, 1991, to collect its capacity-related costs associated with certain long-term power arrangements through its base rates. Prior to July 1, Commonwealth Electrin was recovering the entire capacity-related portion of purchased power through its Fuel Charge. This was the same method of recovery used by Commonwealth

        . Electric prior to its January 1989 retail rate increase.

On July 30, 1990, Cambridge Electric and Commonwealth Electric received DPU approvsl to recover conservation and load management (C&LM) costs through their respective Fuel C 'rge. The C&LM programs were developed in 1988 in collaboration with ocher Massachusetts electric utilities as well as the Conservation Law Foundation of New England, Inc., the Massachusetts Attorney General and other public interest groups and offer opportunities to all customers to save energy by investing in C&LM measures. The overall benefit of the programs vill be to reduce capacity and energy requirements which thereby reduce the cost of providing service. For further information, refer to Note 8 of the Notes to Consolidated Financial Statements filed under Item 8 of this report. Upon the declaration of commercial operation in 1990, Canal began l recovering 100% of its Seabrook 1 investment through power contracts with Commonwealth Electric and Cambridge Electric, subject to refund pending a full FERC review of Cansl's investment in the unit by the l FERC. On December 6, 1991, a FERC Administrative Law Judge (ALJ) l issued an initial ruling affirming the prudence of Canal's oversight of emergency response planning for Seabrook. The ALJ further agreed with Canal that all costa were prudently incurred and therefore just and reasonable. Although a final FERC order has not been received, it is expected that the FERC will uphold the ALJ's ruling. Commonwealth L

Rates. Reaulation and Lealslation (Continued) (b) Automatic Adiustment Clauses (Continued) Electric and Cambridge Electric have been billing, subject to refund, Seabrook 1 charges to their retail customers since August 1, 1990 through Fuel Charge decimals approved by the DPU. Prior to commercial operation, Cambridge Electric and commonwealth Electric collected, subject to refund, approximately 50% of pre-commercial financing costs related to seabrook 1. Cambridge Electric and Commonwealth Electric are collecting, through their respective Fuel Charge, amounts being billed to them by Canal Electric for costs associated with Seabrook 2 (over a ten-year . period) pursuant to a Capacity Acquisition Agreement and both FERC and DPU approval. ftA1 Commonwealth Gas has a standard seasonal cost of gas adjustment rate schedule which provides for the recovery, from firm customers, of purchased gas costs not collected through base rates. These adjust-ment charges,- which require DPU approval, are estimated semi-annually and include credits for gas pipeline refunds and profit margins applicable to interruptible sales. Actual gas costs are reconciled annually as of October 31 and any difference is included as an adjustment in the calculation of the decimals for the two subsequent six-month periods. Periodically, Commonwealth Gas is required to file a long-range forecast of the needs and requirements of its market area and annual supplements thereto with the Massachusetts Energy Facilities Siting Council (the Council). To approve a long-range forecast, the Council must find, among other things, that Commonwealth Gas's plans for con-struction of new gas manufacturing or storage facilities and certain high-pressure gas pipelines are consistent with current health, envi-ronmental protection and resource use and development policies as adopted by the Commonwealth of Massachusetts. Commonwealth Gas filed a long-range forecast with the Council on July 20, 1990 and updated aspects of the filing in March 1991. This forecast remains pending before the Council. (c) Gas Demand and Tako-or-Pav Costs Commonwealth Gas is obligated to pay demand charges pursuant to long-term firm contracts with its principal suppliers which are recovered from customers through a cost of gas adjustment clause (CGA).

The settle-ment was partly in response to recent court cases which rejected the FERC's approval of the purchase deficiency basis for allocating pipeline take-or-pay costs. The settlement, if approved by the FERC, would modify the manner in which the Tennessee taXe-or-pay costs are allocated to customers, increasing Commonwealth Gas Company's cost compared to the purchase deficiency basis rejected by the courts. The settlement would also create a mechanism for recovering prospective take-or-pay costs. Algonquin Gas Transmission Company (Algonquin) has made a series of filings with the FERC to recover from its customers take-or-pay charges imposed on it from its upstream suppliers. As a result, Com-monwealth Gas has been allocated a share of these costs. Algonquin is currently billing Commonwealth Gas for gas supply inventory charges from Texas Eastern Transmission. Company (Texas Eastern) through the Algonquin commodity rate. Both the Texas Eastern and Algonquin contracts are being restructured which will likely result in additional costs to commonwealth Gas. Commonwealth Gas is collecting take-or-pay and other contract restructuring costs imposed by Algonquin and Tennessee from its customers through the CGA as permitted by the DPU. (d) Most Recent Rate Case Proceedinos On April 16, 1991, Commonwealth Gas requested a $27.7 million (11.3%) revenue incrons3 in a filing with the DPU using a test year ended December 31, 1990. This was the first rate increase request since May 1987. On September 16, 1991, the DPU approved a settlement of the revenue requirements portion of the Commonwealth Gas filing. The

       $22.8 million increase in annual revenues represented approximately 82% of the original request and included a return on equity, for accounting purposes, of 13%. The DPU later ruled on the rate design portion of the request and the new rate 3 went into effect on November 1, 1991. The incroace was necessitated by the rising costs of pro-viding service to customers and substantial expenditures to upgrade, improve and maintain the Commonwealth Gas distribution system.

COMMONWEALTH EERGY SYSTEM . FORM 10-K DECEMBER 31, 1991 Item 1. Business (Continued) l 1 Rates, Renulation and Lecislation (Continued) l l (d) Most Recent Rate Case Proceedincs (Continued) On December 31, 1987, Commonwealth Gas received authorization from the DPU to increase base revenues by $12.5 million or 5.6% of total test-year revenues and approximately 80% of the $15.6 million originally requested. The overall rate of return was set at 11.2%, including an allowed return on common equity of 13.25%. This was the first increase for Commonwealth Gas since 1982. In the order, the DPU endorsed Commonwealth Gas's proposal to offer cost-based firm trans-portation services to its industrial customers. On May 17, 1989, Cambridge Electric. filed for an increase in its base rates using a 1988 test year. On August 31, 1989, the DPU approved an Offer of Settlement between the parties which resolved all issues involving revenue requirement. Cambridge Electric was allowed to increase annual revenues by $4,438,000 or 5.5% of total test-year revenue, approximately 73% of the $6,111,000 originally requested. The new rates became effective on December 18, 1989 and represent the first increase in Cambridge Electric's rates since 1982. On May 31, 1988, Cambridge Electric received authorization from the DPU to implement the final stage in its move to equalization of rates of return across rate classes. The revised' rates reflect a settlement agreement which reduced base revenue by $300,000, effective March 1, 1988. In January 1989, Commonwealth Electric received authorization from the DPU to increase base revenues by $18 million or 6.6% of total

   , test-year revenues. This increase represented approximately 77% of its original $23.3 million request and included an overall rate of         -

return of 10.89% and return on common equity of 13% and represented the first increase in Commonwealth Electric's base rates since 1982. As part of this proceeding, the DPU ordered a restructuring of Commonwealth Electric's rates which resulted in significant increases to certain customer rate classes. Subsequently, as a result of c,usto-mer pressure, the Massachusetts state legislature passed, and the Gov-ernor signed, precedent-setting legislation which required that the increase to any ratepayer or class of ratepayers not exceed 7% per year. This legislation became effective February 1, 1990 and speci-fled that in allowed the revision that would January 1989not reduce the amount of annual revenues order. On July 1, 1991, the DPU issued an order increasing Commonwealth Electric's retail electric revenuea by $10.9 million, or 3.1%. The requested incrwase was $17.3 million. The order, based on a June 30, 1990 test year, provides an overall return of 10.49%, including a return on equity of 12%. The DPU also ordered the restructuring of the Company's rates to more closely reflect the actual cost of

Further, the DPU ordered Commonwealth Electric to undertake an independent management audit in 1992 to address, among other areas, its management, planning and control practices. On February 14, 1992, Ernst & Young was selected by the DPU from three qualified management consulting firms submitted by Commonwealth Electric to perform the audit. The audit began on March 6, 1992. (e) Economic Development Rate In an effort to foster industrial development in its service area, Commonwealth Electric filed a new Economic Development Rate with the DPU in mid-September. The rate,'bich was approved by the DPU, became effective on October 1, 1991 (t is being offered to new or existing industrial customers who have an electric demand of 500 kilowatts or more and meet specific financial critoria. Eligible customers must also be one of the 20 largest industrial employers in the city or town or recognized as a major employer in the smaller towns. The rate is available for a six-year term. Nineteen indus-trial customers are presently benefiting from this special rate. (f) Other As a result of the Tax Reform Act of 1986, the DPU issued an order on June 1, 1987 requiring essentially all utilities under its jurisdiction to file new rates, effective July 1, 1987, to reflect the lower revenue requirement caused by the tax rate reduction. As a result, Cambridge Electric, Commonwealth Gas and Commonwealth Electric filed revised rates that reduce annual revenues by $787,000,

     $3,201,000 and $4,006,000, respectively. Subsequently, as discussed above, all three companies completed base rate proceedings affecting their total costs of providing service, including income taxes.

Replacement Power Costs In connection with its ongoing review of the fuel and purchased power costs of certain Massachusetts electric companies, the DPU reviews the operating performance of all plants from which power is obtained.
