The generation mix is diversified and includes coal,nuclear, gas, oil, hydro and purchased power. Our strategy forour electric generation operations focuses on serving customers(Partnership) .; , _ Natural Gas Underground Storage PoolsElectric Transmission Lines(Bulk delivery)A Cove Point LNG Facility .. ‘ ..in the energy intensive Northeast, Mid-Atlantic and Midwestregions of the United States.-Our generation facilities are located in Virginia,’ West Virginia,North Carolina, Connecticut, Illinois, Indiana, Pennsylvania, Ohio,Massachusetts, Rhode Island and Wisconsin. Dominion Gen-eration also includes energy marketing and risk managementactivities associated with the optimization of generation assets.CompetitionRetail choice has been available f6r Dominion GenerEtion’sVirginia jurisdictional electric utility customers since January 1,2003; however, to date, competition in Virginia has not devel-oped to the extent originally anticipated. See Reguiatton-StateRegulations: Currently, North Carolina does not offer retail choiceto electric customers.Dominion Generation’s merchant generation fleet owns andoperates several large facilities in the Midwest. The output fromthese generating plants is sold under long-term contracts and istherefore largely unaffected by competition.The majority of Dominion Generation’s remaining merchantassets operate within functioning RTOs. Competitors includeother generating assets bidding to operate within the RTOs.These RTOs have clearly identified market rules that ensure thecompetitive wholesale market is functioning properly. DominionGeneration’s merchant units have a variety of short arid medium-term contracts, and also compete in the spot market with othergenerators to sell a variety of products including energy, capacity3

and operating reserves. It is difficult to compare various types ofgeneration given the wide range of fuels, fuel procurement strat-egies, efficiencies and operating characteristics of the fleetwithin any given RTO. However, management believes that wehave the expertise in operations, dispatch and risk managementto maximize the degree to which our merchant fleet is com-petitive compared to like assets within the region.RegulationIn Virginia and North Carolina, our electric utility generation facili-ties, along with power purchases, are used to serve our utilityservice area obligations. Due to amendments to the VirginiaRestructuring Act and the fuel factor statute in 2004, revenuesfor serving Virginia jurisdictional retail load are based on cappedbase rates through 2010 and the related fuel costs for thegenerating fleet, including power purchases, are subject to fixedrate recovery provisions until July 1, 2007, when a one-timeadjustment will be made effective through December, 2010.Such adjustment will be prospective and will not take intoaccount any over-recovery or under-recovery of prior fuel costs.Subject to market conditions, any generation remaining aftermeeting utility system needs is sold into PJM.PropertiesFor a listing of Dominion Generation’s generation facilities, seeItem 2. Properties.Sources of Fuel Supply -Dominion Generation uses a variety of fuels to power its electricgeneration, as described below.Nuclear Fuel-Dominion Generation primarily utilizes long-term contracts to support its nuclear fuel requirements. World-wide market conditions are continuously evaluated to ensure arange of supply options at reasonable prices. Current agree-ments, inventories and spot market availability are expected tosupport current and planned fuel supply needs. Additional fuel ispurchased as required to ensure optimal cost and inventorylevels.Fossil Fuel-Dominion Generation primarily utilizes coal, oiland natural gas in its fossil fuel plants. Dominion Generation’scoal supply is obtained through long-term contracts and spotpurchases. Additional utility requirements are purchased mainlyunder short-term spot agreements.Dominion Generation’s natural gas and oil supply is obtainedfrom various sources including: purchases from major andindependent producers in the Mid-continent and Gulf Coastregions; purchases from local producers in the Appalachian area;purchases from gas marketers; and withdrawals from under-ground storage fields owned by us or third parties.-We have a portfolio of firm natural gas transportation con-‘tracts (capacity) that allow flexible natural gas deliveries to ourgas turbine fleet, while minimizing costs.Seasonalitya, y , .Dominion Generation’s sales of electricity typically vary season-ally based on demand for electricity by residential and commer-cial customers for cooling and heating use based on changes intemperature.Nuclear DecommissioningDominion Generation has a total of seven licensed, operatingnuclear reactors, at its Surry and North Anna plants in Virginia, itsMillstone plant in Connecticut and its Kewaunee plant inWisconsin.Surry and North Anria serve customers of our regulated elec-tric utility operations. Millstone Is a nonregulated merchant plantwith two operating units. A third Millstone unit ceased operationsbefore we acquired the plant. In July 2005, we completed theacquisition of the 556-megawatt Kewaunee nuclear power sta-tion in eastern Wisconsin.Decommissioning represents the decontamination and removalof radioactive contaminants from a nuclear power plant once oper-ations have ceased, in accordance with standards established bythe Nuclear Regulatory Commission (NRC). Amounts collected fromratepayers and placed in trusts have been invested to fund futurecosts of decommissioning the Surry and North Anna units. As partof our acquisition of both Millstone and Kewaunee, we acquired thedecommissioning funds for the related units. Currently, we believethat the amounts available in our decommissioning trusts and theirexpected earnings will be sufficient to cover expected decom-missioning costs for the Millstone and Kewaunee units, without anyadditional contributions to those trusts.The total estimated cost to decommission our eight nuclearunits is $3.5 billion and is primarily based upon sitespecificstudies completed in 2002. We will perform new cost studies in2006. For all units except Millstone Unit 1 and Unit 2, the cur-rent cost estimates assumie decommissioning activities willbegin shortly after cessation of operations, which will occur whenthe operating licenses expire. Millstone’ Unit 1 is not in serviceand selected nilnor decommissioning activities are being per-formed. This unit will continue to be monitored until decom-missioning activities begin for the remaining Millstone units. Thecurrent operating licenses expire in the years detailed in thefollowing table. During 2005, the NRC approved Dominion’sapplication for a 20-year life extension for Millstone Units 2 and-3. We expect to decommission the Surry and North Anna unitsduring the period 2032 to 2045.: We expect to start minordecommissioning activities at Millstone Unit 2 in 2034, with fulldecommissioning to take place at Millstone Units 2 and 3 duringthe period 2045 to 2057. We plan to file an application for a 20-year life extension for our Kewaunee unit. If the NRC approvesthe application, we currently expect to decommission Kewauneeduring the period 2032 to 2042., ;,t..; !, IsI .-.I- 1t .!..: I.-.II I4

These operations are located inseveral major producing basins in the lower 48 states, inclutding’the outer continental shelf and deepwater areas of the Gulf ofMexico, and WVestern Canada.CompetitionDominion E&P”s competitors range from major, international oilcompanies to smaller, independent producers. Dominion E&Pfaces significant competition in the bidding for federal offshoreleases and in obtaining leases and drilling rights for onshoreproperties. As the operator of a number of properties, DominionE&P also faces competition in securing drilling equipment andsupplies for exploration and development.In terms a its production activities, Dominion E&P sells mostof its delivera )le natural gas and oil into short and intermediate-term markets. Dominion E&P faces challenges related to themarketing of its natural gas and oil production due to the con-traction of participants in the energy marketing industry. How-ever, Dominion E&P owns a large and diverse natural gas and oilportfolio and maintains an active gas and oil marketing presencein its primary production regions, which strengthens its knowl-edge of the marketplace and delivery options.Regulation ., AOur exploration and production operations are subject to regu-lation by numerous federal and state authorities. The pipelinetransportation of our natural gas production is regulated by FERCand pipelines operating on or across the Outer Continental Shelfare subject to the Outer Continental Shelf Lands Act whichrequires open-access, non-discriminatory pipeline facilities. Ourproduction operations in the Gulf of Mexico and most of ouroperations in the western United States are located on federaloil and gas leases administered by the Minerals ManagementService (MMS) or the Bureau of Land Management. Theseleases are issued through a competitive bidding process and’require us to comply with stringent regulations. Offsl-ore pro-duction facilities must comply with MMS regulations relating toengineering, construction and operational specifications and theplugging and abandonment of wells. Our production operationsare also subject to numerous environmental regulations includingregulations relating to oil spills into navigable waters of theUnited States. See Regulation-Federal Regulations and Regu-lation-Environmental Regulation for additional information.PropertiesDominion E&P owns 6.3 trillion cubic feet of proved e quivalent ofnatural gas and oil reserves and produces approximately 1.1billion cubic feet equivalent of natural gas per day from itsleasehold acreage and facility investments. We, either alone orwith partners, hold interests in natural gas and oil lease acreage,wellbores, well facilities, production platforms and gatheringsystems. We also own or hold rights to seismic data and othertools used in exploration and development drilling activities. Ourshare of developed leasehold totals 3.1 million acres, withanother 2.4 million acres held for future exploration Enddevelopment drilling opportunities. See also Item 2.
