Item 1. Business General Commonwealth Energy System, a Massachusetts trust, is an unincorporated business organization with transferable shares. It is organized under a Declaration of Trust dated December 31, 1926, as amended, pursuant to the laws of Massachusetts. It is an exempt public utility holding company under the provisions of the Public 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, together with its subsidiaries, is collectively referred to as "the system." The operating utility subsidiaries of the System are engaged in the generation, transmission and distribution of electricity and the distribution of natural gas, all within Massachusetts. These subsidiaries are: Electric Gas Cambridge Electric Light Company Commonwealth Gas Company Canal Electric 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), five real estate trusts and a liquefied natural gas (LNG) and vaporization facility (Hopkinton LNG Corp.). Subsidiaries of the System have common executive and financial management and receive technical 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, which is a joint-owner of the Riverfront Office Park complex in Cambridge; COM/Energy Acushnet Realty, which leases land to Hopkinton LNG Corp. (Hopkinton); 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. As a result of unsuccessful efforts to develop an energy park on this site, the System wrote down its investment in the Freetown project and plans to sell the property. Each of the operating utility subsidiaries serves retail customers except for Canal Electric Company (Canal) which operates an electric generating station located 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) (an unaffiliated company). Canal Unit 2 is operated under an agreement with Montaup which provides for the equal sharing of output, fixed charges and operating expenses. In October 1993, Canal reached an agreement with Montaup and Algonquin Gas Transmission Company to build a natural gas <PAGE 4> COMMONWEALTH ENERGY SYSTEM pipeline that will serve Unit 2, subject to regulatory approvals. The project will improve air quality on Cape Cod, enable the plant to exceed the stringent 1995 air quality standards established by the Massachusetts Department of Environmental Protection and strengthen Canal's bargaining position as it seeks to secure the lowest-cost fuel for its customers. Plant conversion and pipeline construction are expected to be completed in 1996. Electric service is furnished by Cambridge Electric Light Company (Cam- bridge Electric) and Commonwealth Electric Company (Commonwealth Electric) at retail to approximately 308,000 year-round and 49,000 seasonal customers in 41 communities in eastern Massachusetts covering 1,112 square miles and having an aggregate population of 645,000. The territory served includes the communities of Cambridge, New Bedford and Plymouth and the geographic area comprising Cape Cod and Martha's Vineyard. Cambridge Electric also sells power at wholesale to the Town of Belmont, Massachusetts. Natural gas is distributed by Commonwealth Gas Company (Commonwealth Gas) to approximately 232,000 customers in 49 communities in central and eastern Massachusetts 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. 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 20 customers in Cambridge and one customer (Massachusetts General Hospital) in Boston. Steam is used for space heating and other purposes. On August 17, 1993 COM/Energy Steam began providing steam service to Genzyme Corporation (Genzyme), a biotechnology company that is expected to become one of its largest customers. Genzyme's steam need for 1995 is estimated to be 83.3 million pounds, which represents approximately 5% of steam unit sales, for heating, air conditioning and testing processes. In 1996, Genzyme's annual requirement is estimated to reach approximately 175 million pounds based upon the expectation of commercial manufacturing of a biotherapeutic product in 1995. Industry in the territories served by system companies is highly diversified. The larger industrial customers include high-technology firms and manufacturers of such products as photographic equipment and supplies, rubber products, textiles, wire and other fastening devices, abrasives and grinding wheels, candy, copper and alloys, and chemicals. Among customers served are several major educational institutions, including Harvard University (Harvard) and the Massachusetts Institute of Technology (MIT). MIT has completed construction of a 19 MW natural gas-fired cogeneration facility which is expected to be in operation in 1995. MIT anticipates this cogeneration facility will meet approximately 94% of its power, heating and cooling requirements. Sales to MIT in 1994 accounted for approximately 1.8% of total unit sales. MIT and Cambridge Electric were unsuccessful in attempts to reach agreement on the cost to provide back up and supplemental service. In March 1995, Cambridge Electric filed four rate schedules with the Massachusetts Department of Public Utilities (DPU) which, in part, seek to recover costs incurred to serve large customers such as MIT. These rates <PAGE 5> COMMONWEALTH ENERGY SYSTEM include costs associated with providing standby, maintenance and supplemental service on an ongoing basis as well as a customer transition charge to recover other costs incurred to serve its largest customers should they discontinue service with Cambridge Electric while remaining in Cambridge. In March 1994, Cambridge Electric was successful in negotiating a seven- year service agreement with another large customer, Harvard, whose sales in 1994 accounted for approximately 1.6% of the System's total unit sales. Electric Power Supply 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 and other non-utility generators through a competitive bidding process that is regulated by the DPU. System companies own generating facilities with a capability totaling 1,046.5 MW at December 31, 1994. Including 560 MW provided by Canal Unit 1, of which three-quarters (420 MW) is sold to neighboring utilities under long- term contracts, and 292.0 MW provided by Canal Unit 2. Another 145.1 MW is provided by various smaller system units. Of the 577.1 MW available to the system, 77.6 MW are used principally for peaking purposes. A 3.52% ownership interest in the Seabrook 1 nuclear power plant 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 1991, Canal executed a transaction with Central Vermont Public Service Corporation (CVPS) whereby 50 MW of Canal Unit 2 was exchanged for 25 MW each of CVPS's entitlement in the Vermont Yankee nuclear power plant and the Merrimack 2 coal-fired unit through October 1995. Additionally, in 1993, Canal extended an agreement with New England Power Company (NEP) whereby 50 MW of Canal Unit 2 (previously 20 MW) is exchanged for 50 MW of Bear Swamp Unit Nos. 1 and 2 through April 1997. The Bear Swamp Units are pumped storage hydro electric generating facilities. These contracts are designed to reduce the system's reliance on oil. In addition, through Canal's equity ownership in Hydro-Quebec Phase II, the system has an entitlement of 67.9 MW. Purchase power arrangements were also in place with the following natural gas-fired cogenerating units in Massachusetts: 23 MW from Lowell Cogeneration Company Limited Partnership (Lowell), 38 MW from Pepperell Power Associates Limited Partnership (Pepperell), 53.0 MW from Northeast Energy Associates, 59.9 MW from Masspower and 58.9 MW from Altresco Pittsfield. Additionally, the system receives 67.0 MW from the SEMASS waste-to-energy plant (which includes 20.8 MW from the expansion unit which went on-line in May 1993); has entitlements totaling 24.4 MW through contracts with five (5) hydroelectric suppliers, including 20 MW from Boott Hydropower, Inc., in Lowell, Massachusetts; and also receives 68.2 MW from a natural gas-fired independent power producer, Dartmouth Power Associates. The system anticipates providing for future peak load plus reserve requirements through existing system generation, including purchasing <PAGE 6> COMMONWEALTH ENERGY SYSTEM available capacity from neighboring utilities and/or non-utility generators. Effective January 1, 1995, the system negotiated a restructured power sale agreement with Lowell and terminated the Pepperell power sale agreement through a buy-out arrangement, effective January 27, 1995. In addition, the system has available 140.7 MW from four nuclear units in which system distribution companies have life-of-the-unit contracts for power. Information with respect to these units is as follows: Connecticut Maine Vermont Yankee Yankee Yankee Pilgrim Year of Initial Operation 1968 1972 1972 1972 Contract Expiration Date 1998 2008 2012 2012 Equity Ownership (%) 4.50 4.00 2.50 - Plant Entitlement (%) 4.50 3.59 2.25 11 Plant Capability (MW) 560.0 870.0 496.0 664.7 System Entitlement (MW) 25.2 31.2 11.2 73.1 On February 26, 1992, the Yankee Atomic Electric Company (Yankee) board of directors agreed to permanently cease power operation of the Yankee nuclear power plant in Rowe, Massachusetts. For additional information, refer to Note 2(e) of the Notes to Consolidated Financial Statements filed under Item 8 of this report. One of the operating nuclear units, located in Wiscasset, Maine and operated by Maine Yankee Atomic Power Company, has been experiencing degradation of its steam generator tubes, principally in the form of circumferential cracking, which until early 1995 was believed to be limited to a relatively small number of tubes. During a refueling and maintenance outage that began in early February 1995, Maine Yankee, through the use of new inspection methods, detected increased degradation of the tubes well above its expectations. Maine Yankee is currently evaluating alternative courses of action to remedy this situation, most of which could result in significant capital expenditures and an extended outage period. At this time, Cambridge Electric cannot predict what action will be needed to rectify the situation, the costs to be incurred or the length of the outage. The Board of Directors of Maine Yankee will be meeting in early April 1995 to consider various options. On October 1, 1992, Commonwealth Electric ceased power generation at its 60 MW Cannon Street generating station located in New Bedford, Massachusetts. During the past few years, the plant had been used primarily to meet peak electric demand and as a backup unit for Commonwealth Electric and the New England Power Pool (NEPOOL). A sharp decline in electric demand brought about by the present economic slowdown was the key factor in management's decision to close the plant. This decision was viewed as the most cost-effective among several alternatives and leaves Commonwealth Electric with the most flexibility for future capacity planning. Cambridge Electric, Canal and Commonwealth Electric, together with other electric utility companies in the New England area, are members of NEPOOL, which was formed in 1971 to provide for the joint planning and operation of electric systems throughout New England. <PAGE 7> COMMONWEALTH ENERGY SYSTEM 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. NEPOOL, on behalf of its members entered into an Interconnection Agree- ment with Hydro-Quebec, a Canadian utility operating in the Province of Quebec. The agreement provided for construction of an interconnection (referred to as the Hydro-Quebec Project-Phase I and Phase II) between the electrical systems of New England and Quebec. The parties have also entered into an Energy Contract and an Energy Banking Agreement; the former obligates Hydro-Quebec to offer NEPOOL participants up to 33 million MWH of surplus energy during an eleven-year term that began September 1, 1986 and the latter provides for energy transfers between the two systems. 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. Canal is obligated to pay its share of operating and capital costs for Phase II over a 25 year period ending in 2015. Future minimum lease payments for Phase II have an estimated present value of $13.8 million at December 31, 1994. In addition, Canal has an equity interest in Phase II which amounted to $3.8 million in 1994 and $3.9 million in 1993. The System's electric subsidiaries are also members of the Northeast Power Coordinating Council (NPCC), an advisory organization that 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 coordination in the planning and operation of these systems. The reserve requirements used by the NEPOOL participants in planning 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 Agreements 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. Additionally, Cambridge Electric and Commonwealth Electric have long-term contracts for the purchase of electricity from various sources. Generally, these contracts are for fixed periods and require payment of a demand charge for the capacity entitlement and an energy charge to cover the cost of fuel. For additional information concerning system commitments under long-term power contracts, refer to Note 2(d) of Notes to Consolidated Financial Statements filed under Item 8 of this report. 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. For additional information <PAGE 8> COMMONWEALTH ENERGY SYSTEM concerning Seabrook 1, refer to Note 2(b) of Notes to Consolidated Financial Statements filed under Item 8 of this report. Electric Fuel Supply (a) Oil Imported residual oil is the fuel used in the generation of power in system generating plants, producing approximately 24% of the system's total energy requirement for 1994. Effective July 1, 1993, Canal executed a twenty-two month contract with Coastal Oil of New England, Inc. (Coastal) for the purchase of residual fuel oil. The contract provides for delivery of a set percentage of Canal's fuel requirement, the balance (a maximum of 20%) to be met by spot purchases or by Coastal at the discretion of Canal. Through December 31, 1994, approximately 16% of Canal's total requirements have been met by lower-cost spot purchases. Energy Supply and Credit Corporation (ESCO) operates Canal's oil terminal and manages the purchase, receipt and payment of oil under assignment 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 60 days of normal operation of the two units. During 1994, ESCO maintained an average daily inventory of 575,000 barrels of fuel oil which represents 30 days of normal operation of the two units. This supply is maintained by tanker deliveries 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 discussion of the cost of fuel oil. (b) Nuclear Fuel Supply and Disposal Approximately 25% of the system's total energy requirement for 1994 was generated by nuclear plants. The nuclear fuel contract and inventory informa- tion for Seabrook 1 has been furnished to the system by North Atlantic Energy Services Corporation (NAESCO), the plant manager responsible for operation of the unit. Seabrook's requirement for nuclear fuel components are 100% covered through 1999 by existing contracts. There are no spent fuel reprocessing or disposal facilities currently operating in the United States. Instead, commercial nuclear electric generating units operating in the United States are required to retain high level wastes and spent fuel on-site. As required by the Nuclear Waste Policy Act of 1982 (the Act), as amended, the joint-owners entered into a contract with the Department of Energy for the transportation and disposal of spent fuel and high level radioactive waste at a national nuclear waste repository or a monitored retrievable storage facility. Owners or generators of spent nuclear fuel or its associated wastes are required to bear all of the costs for such transportation and disposal through payment of a fee of approximately <PAGE 9> COMMONWEALTH ENERGY SYSTEM 1 mill/KWH based on net electric generation to the Nuclear Waste Fund. Under the Act, a temporary storage facility for nuclear waste was anticipated to be in operation by 1998; however, a reassessment of the project's schedule requires extending the completion date of the permanent facility until at least 2010. Seabrook 1 is currently licensed for enough on-site storage to accommodate all spent fuel expected to be accumulated through at least the year 2010. Gas Supply In April 1992, the Federal Energy Regulatory Commission (FERC) issued Order No. 636 (Order 636) which became effective on November 1, 1993. The order requires interstate pipelines to unbundle existing gas sales contracts into separate components (gas sales, transportation and storage services) and to provide transportation services that allow customers to receive the same level and quality of service they had with the previous bundled contracts. Prior to the implementation of Order 636 Commonwealth Gas purchased the majority of its gas supplies from either Tennessee Gas Pipeline Company (Tennessee) or Algonquin Gas Transmission Company (Algonquin), supplemented with third-party firm gas purchases, storage services, and firm transportation from various pipelines. Presently, Commonwealth Gas purchases only transportation, storage, and balancing services from these pipelines (and other upstream pipelines that bring gas from the supply wells to the final transporting pipelines) and procures all of its gas supplies from third-party vendors, utilizing firm contracts with terms ranging from less than one year to three or more years. The vendors vary from small independent marketers to major gas and oil companies. For additional information on Order 636, refer to Note 2(g) of Notes to Financial Statements filed under Item 8 of this report. In addition to firm transportation and gas supplies mentioned above, Commonwealth Gas utilizes contracts for underground storage and LNG facilities to meet its winter peaking demands. The underground storage contracts are a combination of existing and new agreements which are the result of Order 636 service unbundling. The LNG facilities, described below, are used to liquefy and store pipeline gas during the warmer months for use during the heating season. During 1994, over 98% of the gas utilized by Commonwealth Gas was delivered by the interstate pipeline system, the remaining small quantity (approximately 662,000 MMBTU) was delivered as liquid LNG from Distrigas of Massachusetts. Commonwealth Gas entered into a multi-party agreement in 1992 to assume a portion of Boston Gas Company's contracts to purchase Canadian gas supplies from Alberta Northeast (ANE), and have the volumes delivered by the Iroquois Gas Transmission System and Tennessee pipelines. The ANE gas supply contract was filed with the DPU and hearings were completed in April 1993. Commonwealth Gas is currently awaiting an order from the DPU. Commonwealth Gas began transporting gas on its distribution system in 1990 for end-users. There are currently eleven customers using this transpor- tation service, accounting for 2,208 BBTU (4.5%) of system throughput in 1994. <PAGE 10> COMMONWEALTH ENERGY SYSTEM Hopkinton LNG Facility A portion of Commonwealth Gas' gas supply during the heating season is 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, Massachusetts with an aggregate capacity of 500,000 MCF of natural gas and are filled with LNG trucked from Hopkinton. Commonwealth Gas has a contract for LNG service with Hopkinton ex- tending through 1996, thereafter renewable year to year with notice of termination due five years in advance. Contract payments include a demand charge sufficient to cover 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. Based upon information presently available regarding projected growth in demand and estimates of availability of future supplies of pipeline gas, Commonwealth Gas believes that its present sources of gas supply are adequate to meet existing load and allow for future growth in sales. Rates, Regulation and Legislation 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, Canal, Cambridge Electric and Commonwealth Electric file their respective wholesale rates with the FERC. (a) Most Recent Rate Case Proceedings Electric On May 28, 1993, the DPU issued an order increasing Cambridge Electric's retail revenues by approximately $7.2 million, or 6.4%. The rates, based on a June 30, 1992 test-year and effective June 1, 1993, provide an overall return of 9.95%, including an equity return of 11% and represented approximately 70% of the amount requested. The new rates reflect the costs associated with postretirement benefits other than pensions which were determined in accordance with Statement of Financial Accounting Standards No. 106, "Employers' Accounting for Postretirement Benefits Other Than Pensions," adopted as of January 1, 1993. The DPU authorized full recovery of these costs over a four-year phase-in period with carrying costs on the deferred portion. The new base rates also reflect the roll-in of costs associated with the Seabrook nuclear power plant which are billed to Cambridge Electric by Canal. Previously these costs were recovered through Cambridge Electric's Fuel Charge decimal. <PAGE 11> COMMONWEALTH ENERGY SYSTEM On July 1, 1991, the DPU issued an order increasing Commonwealth Elec- tric's retail electric revenues by $10.9 million, or 3.1%. The requested increase was $17.3 million. The order, based on a June 30, 1990 test-year, provided an overall return of 10.49%, including a return on equity of 12%. Gas On April 16, 1991, Commonwealth Gas requested a $27.7 million (11.3%) revenue increase in a filing with the DPU using a test-year ended December 31, 1990. On September 16, 1991, the DPU approved a settlement of the revenue requirements portion of the filing authorizing a $22.8 million increase in annual revenues, approximately 82% of the original request. The agreement included a return on equity, for accounting purposes, of 13%. The DPU later ruled on the rate design portion of the request and new rates went into effect on November 1, 1991. In May 1994, Commonwealth Gas requested the DPU to change the backup service charges under its firm transportation rate. Back up charges result when Commonwealth Gas sells gas from its system supplies to a customer whose off-system gas supply has failed or is temporarily unavailable for causes beyond the customer's control. The change involved an upward indexing based on changes in the gas supply demand costs occasioned by Order 636. On December 22, 1994, the DPU approved Commonwealth Gas' requested change effective January 1, 1995. This change, which has no effect on revenue, results in a more equitable recovery of pipeline capacity costs between Commonwealth Gas' total requirements and transportation customers. (b) Wholesale Rate Proceedings Cambridge Electric requires FERC approval to increase its wholesale rates to the Town of Belmont, Massachusetts (Belmont), a "partial requirements" customer since 1986. These rates include a fuel adjustment clause which reflects changes in costs of fuels and purchased power used to supply Belmont. During March of 1993, Cambridge Electric and Belmont signed a net requirements power supply agreement, the terms and conditions of which required Belmont to pay for all costs except transmission fees which Cambridge Electric and Belmont attempted to negotiate. The negotiations were not successful and Cambridge Electric filed for approval of transmission rates with the FERC on June 29, 1994. The FERC accepted the rates effective January 25, 1995, subject to refund. At the same time, an investigation was opened by the FERC to determine the reasonableness of both the existing and the proposed transmission rates charged to Belmont. Cambridge Electric filed its case with the FERC on October 25, 1994 and hearings are scheduled to begin during the second quarter of 1995. (c) Automatic Adjustment Clauses Electric Both Commonwealth Electric and Cambridge Electric have Fuel Charge rate schedules which generally allow for current recovery, from retail customers, of fuel used in electric production, purchased power and transmission costs. <PAGE 12> COMMONWEALTH ENERGY SYSTEM These schedules require a quarterly computation and DPU approval of a Fuel Charge decimal based upon forecasts of fuel, purchased power, transmission costs and billed unit sales for each period. To the extent that collections under the rate schedules do not match actual costs for that period, an appropriate adjustment is reflected in the calculation of the next subsequent calendar quarter decimal. Cambridge Electric and Commonwealth Electric collect a portion of the capacity-related purchased power costs associated with certain long-term power arrangements through base rates. The recovery mechanism for these costs uses a per kilowatthour (KWH) factor that 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 Electric and Commonwealth Electric experience a revenue excess or shortfall which can have a significant impact on net income. All other capacity and energy-related purchased power costs are recovered through the Fuel Charge. Cambridge Electric and Commonwealth Electric made a filing in late 1992 with the DPU seeking an alternative method of recovery. This request was denied in a letter order issued on October 6, 1993. However, the companies were encouraged by the DPU's acknowledgement that the issues presented warrant further consideration. The DPU encouraged each company to continue to work with other interested parties, including the Attorney General of Massachusetts, to reach a consensus solution on the issue for future consideration. The companies have been involved in discussions with interested parties in an effort to resolve this issue in a positive fashion and hope to reach an agreement in the near future. Both Commonwealth Electric and Cambridge Electric have separately stated Conservation Charge rate schedules which allow for current recovery, from retail customers, of Conservation and Load Management program costs. For further information, refer to Management's Discussion and Analysis of Financial Condition and Results of Operations filed under Item 7 of this report. Gas Commonwealth Gas has a Standard Seasonal Cost of Gas Adjustment rate schedule (CGA) which provides for the recovery, from firm customers, of purchased gas costs not collected through base rates. These schedules, 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. The DPU and the Massachusetts Energy Facilities Siting Council (the Council) were merged in 1992. The Council is now a division of the DPU. Periodically, Commonwealth Gas is required to file a long-range forecast of the energy needs and requirements of its market area and annual supplements thereto with the Council. To approve a long-range forecast, the Council must find, among other things, that Commonwealth Gas plans for construction of new gas manufacturing or storage facilities and certain high-pressure gas pipelines are consistent with current health, environmental protection, and resource use and development policies as adopted by the Commonwealth of <PAGE 13> COMMONWEALTH ENERGY SYSTEM 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 was combined with the DPU review of the ANE contract. Both issues are pending before the DPU. (d) Gas Demand, Take-or-Pay Costs and Transition Costs Commonwealth Gas is obligated, as part of its pipeline transportation and supplier gas purchase contracts, to pay monthly demand charges which are recovered through the CGA. In June 1991, Tennessee filed a settlement with the FERC dealing with a variety of contract restructuring issues, including the allocation of take-or- pay costs to Tennessee's customers including Commonwealth Gas. This comprehensive settlement was approved and implemented on July 1, 1992. As part of the settlement, the allocation of take-or-pay costs was changed from a deficiency basis to a contract demand basis which increased Commonwealth Gas' allocation. There are still some small on-going amounts of take-or-pay costs being collected by the pipeline, however, Tennessee has nearly reached the cap of allowable collections under the settlement. Algonquin made a series of filings with the FERC to recover from its customers take-or-pay charges imposed on it by its upstream suppliers. Algonquin billed Commonwealth Gas for gas supply inventory charges from Texas Eastern and others through the Algonquin commodity rate. With the implementation of Order 636, Algonquin allocated the remaining costs utilizing a formula based on actual purchases for the twelve months prior to May 1, 1993. Commonwealth Gas' allocation was in excess of $5 million. Commonwealth Gas successfully appealed Algonquin's allocation method to the FERC. The change in allocation, combined with issues being settled in Algonquin's current rate case will reduce Commonwealth Gas' allocated share to $2.5 million. In addition, a settlement was reached with Koch Gateway Pipeline (formerly the United Gas Pipeline) whereby Commonwealth Gas received approximately $2 million in refunds for take-or-pay costs allocated through Texas Eastern and Algonquin since 1985. This amount is currently being refunded to firm customers through the CGA. Commonwealth Gas is collecting all contract restructuring costs from its customers through the CGA as permitted by the DPU. Competition This past year, the system continued to develop and implement strategies to deal with the increasingly competitive environment in our gas and electric businesses. The inherently high cost of providing energy services in the Northeast has placed the region at a competitive disadvan- tageas more customers begin to explore alternative supply options. Many state and federal government agencies are considering implementing programs under which utility and non-utility generators can sell electricity to customers of other utilities without regard to previously closed franchise service areas. In 1994, the DPU began an inquiry into incentive rate-making and in February 1995 opened an investigation into electric industry restructuring. <PAGE 14> COMMONWEALTH ENERGY SYSTEM Actions by system companies in response to the new competitive challenges have been well received by regulators, business groups and customers. For a more detailed discussion of competition and the programs currently in place within the system, refer to the "Competition" section of Management's Discussion and Analysis of Financial Condition and Results of Operation filed under Item 7 of this report. Segment Information System companies provide electric, gas and steam services to retail customers in service territories located in central and eastern Massachusetts and, in addition, sell electricity at wholesale to Massachusetts customers. Other operations of the system include the development and management of new real estate ventures and operation of rental properties and other investment activities which do not presently contribute significantly to either revenues or operating income. Reference is made to additional industry segment information in Note 10 of Notes to Consolidated Financial Statements filed under Item 8 of this re- port. Environmental Matters The system is subject to laws and regulations administered by federal, state and local authorities relating to the quality of the environment. System compliance with these laws and regulations will require capital expenditures of $41.8 million from 1995 through 1999 for the electric and gas divisions. For additional information concerning environmental issues including those relating to former gas manufacturing sites, refer to the "Environmental Matters" section of "Management's Discussion and Analysis of Financial Condi- tion and Results of Operations" filed under Item 7 of this report. Construction and Financing For information concerning the system's financing and construction programs refer to Management's Discussion and Analysis of Financial Condition and Results of Operations filed under Item 7 and Note 2(a) of the Notes to Consolidated Financial Statements filed under Item 8 of this report. Employees The total number of full-time employees for the system declined 2.2% to 2,169 in 1994 from 2,217 employees at year-end 1993. Of the current total, 1,282 (59%) are represented by various collective bargaining units. Existing agreements are for varying periods and expire in 1995 and thereafter. Employee relations have generally been satisfactory. Item 2. Properties The system's principal electric properties consist of Canal Unit 1, a 569 MW oil-fired steam electric generating unit, and its one-half ownership in Canal Unit 2, a 580 MW oil-fired steam electric generating unit, both located <PAGE 15> COMMONWEALTH ENERGY SYSTEM at Canal Electric's facility in Sandwich, Massachusetts. Other electric properties include an integrated system of distribution lines and substations together with Commonwealth Electric's 60 MW steam electric generating station located in New Bedford, Massachusetts which ceased operations in October 1992 and was abandoned in 1993. Cambridge Electric has two steam electric generating stations with a net capability of 76.5 MW located in Cambridge, Massachusetts. In addition, the system has a 3.52% interest (40.5 MW of capacity) in Seabrook 1 and a 1.4% or 8.9 MW joint-ownership interest in Central Maine Power Company's Wyman Unit 4. The system also has an interest in smaller generating units totaling 77.6 MW used primarily for peaking and emergency purposes. In addition, the system's other principal properties consist of an electric division office building in Wareham, Massachusetts and other structures such as garages and service buildings. At December 31, 1994, the electric transmission and distribution system consisted of 5,790 pole miles of overhead lines, 4,192 cable miles of underground line, 355 substations and 374,055 active customer meters. The principal natural gas properties consist of distribution mains, services and meters necessary to maintain reliable service to customers. At the end of 1994, the gas system included 2,761 miles of gas distribution lines, 162,971 services and 239,302 customer meters together with the necessary measuring and regulating equipment. In addition, the system owns a liquefaction and vaporization plant, a satellite vaporization plant and above- ground cryogenic storage tanks having an aggregate storage capacity equivalent to 3.5 million MCF of natural gas. The system's gas division owns a central headquarters and service building in Southborough, Massachusetts, five district office buildings and several natural gas receiving and take stations. Item 3. Legal Proceedings The system is subject to legal claims and matters arising from its course of business, including its participation in power contract arbitrations as discussed in the "Power Contract Arbitrations" section of Management's Discussion and Analysis of Financial Condition and Results of Operations filed under Item 7 of this report.
