The supply needs that determine the resource requirements of the Operating Companies are driven by six basic resource supply objectives: Provide adequate resources to meet customer peak demands with adequate reliability. Provide low cost base load resources to serve base load requirements (the firm load level that is expected to be exceeded for at least 85% of all hours per year). Reliability Provide efficient, dispatchable load following resources to serve the time varying load shape levels that are above the base load requirement load levels. Provide a generation portfolio that is more efficient and avoids an over-reliance on aging resources. Mitigate the exposure to price volatility associated with uncertainties in fuel and purchased power costs.

MIX TYPE 2. – Total resource requirements for 2006 exceed long-term controlled resources by over 2000 MWs. Needs are increasing with load growth. – To solely address peak period reliability, resource needs could be met by annual or seasonal purchases of peaking/reserve capacity. Determine portfolio mix of generation resources that is consistent with planning objectives and practical constraints. Determine the amount of capacity needed by the System to meet peak period reliability. – CCGT or solid fuel resources needed to address base load supply requirements. – Additional CCGT and CT resources are needed to serve load-following requirements. – Power Purchase Strategy guides amount of power purchase and mix of power purchase products – Long-term LOU resource decisions (timing, fuel type, location, OPCO participation) AMOUNT 3. 1.

Part 1 – Planning Framework Process Overall Guiding Principles Participation in Purchased Power in Annual Supply Plan Participation in Power for System Needs Acquired During Operating Year Long-term Resource Participation Decisions  Each operating company should support a sufficient amount of generation for each supply role used to serve its load shape.  Resource participation decisions for new resources should consider whether each operating company is supporting capability that can be expected to be available for coordinated economic dispatch sufficient to meet its peak load plus provide a reserve of at least 10% (capability does not include MSS-1 reserves). – Resource participation decisions are made at time of the commitment to the resource. – Preliminary (for planning purposes and subject to change) projected resource participation for future resources that are included in the SSRP are made at the time the resource plan is approved. – The Operating Committee determines participation in new resources considering each Operating Company’s need for the new resource’s expected supply role. – Resource participation decisions are made at the time of the commitment to the resource. – The Operating Committee can specifically assign resources to address the specific needs of the operating companies. – After specific resource participation decisions are made, additional resources are allocated based on factors established by the Operating Committee.

The statements contained in this Appendix are made subject to the Reservation of Rights set forth in the RFP and subject to the terms and acknowledgements set forth in the Proposal Submission Agreement. 2006 LONG-TERM RFP - April 17, 2006 8 Factors in Operating Company Participation Part 1 – Planning Framework Supply Risks Relative Total Production Cost Peak Load +10% Reserve Capacity Deficit Baseload Capacity Deficit Load-Following Resource Capacity Deficit Responsibility Ratio Resource participation also will consider supply resource diversity, seeking to reduce the reliability and price risks resulting from and Operating Company’s exposure to single contingency generation outages or from its exposure to generation supplied by one fuel type. Long-term total production cost trends for each Operating Company considering both the overall production costs and the component production costs for each major supply role. Each Operating Company’s resource capability position with regard to a standard seeking to assure that each Operating Company supports its proportionate share of the resources that are expected to be used in the coordinated dispatch in the System’s annual operating plan. The standard seeks to determine participation in new resources by considering those companies who have a “Peak Load +10% Reserve Capacity Deficit,” based upon the Operating Company’s aggregate existing resources (excluding MSS-1 purchases) that are less than its peak load plus a minimum reserve level of 10%. In determining the participation in new base load resources, each Operating Company’s resource position with regard to having a sufficient base load generation resources to serve its base load requirements. Participation in new base load resources would consider the “Baseload Capacity Deficit” defined as the shortfall in base load generation required to serve the firm load level that is expected for greater than 85% of annual hours. In determining the participation in new load-following resources, each Operating Company’s resource position with regard to having sufficient load-following resources to serve its load requirements. Participation in new load-following resources would consider the amount of each Operating Company’s CCGT equivalent load-following resources or other load-following resources that are expected to be regularly utilized in the system’s coordinated dispatch to serve the System’s load following requirements. After each Operating Company has attained its proportionate share of the System’s total resources and its appropriate share of each type of generation resource required for the various supply roles, participation in any additional resources acquired for System purposes will be allocated on responsibility ratio. Operating company participation decisions consider the following factors.

Depending on the particular year in the SSRP, the System expects to acquire approximately 800 to 1600 megawatts (MW) of resources from short-term power purchases consisting of a variety of products. Each year the System expects to purchase several hundred MW of dispatchable load-following generation unit capacity from combined cycle gas turbine (“CCGT”) or combustion turbine (“CT”) generators, pursuant to multi- year unit capacity purchase agreements (“MUCPAs” or “MUCCOs”) with terms of one to three years. In addition to multi-year unit capacity purchases, the System expects to make seasonal and annual power purchases utilizing products such as call options, firm block-energy or liquidated damages products, or other purchased power resources through the use of multiple procurement processes including formal Requests for Proposals (“RFPs”). Part 2 – Strategic Overview Purchase Power Products Include Long-term (life-of-unit) resources including PPAs and acquisitions Limited-term products (one to three years) Seasonal products Monthly RFP purchases Weekly RFP purchases Daily purchases

The decision whether to retire an existing unit is an economic one that requires comparison of the forward cost of the existing unit with the forward cost of alternatives. Many of the System’s older gas and oil-fired units run at low capacity factors. At the same time these units require relatively low forward spending to keep available. Consequently, these units serve the peaking / reserve role in an economic manner. They provide economic sources of capacity. Part 5 – Retirement Strategy
