ing an analysis of installed capacity, planned capacity, and known or forecast retirements. The applicant should describe and explain the factors which affect, or are likely to affect, the current and forecast supply of electricity in the service area. The power supply section should include a description of the regulatory, statutory, and/or business drivers, which may influence current fleet and future supply decisions. The applicant should provide any known or forecast factors that could affect uncertainty, with an emphasis on their likelihood. Examples include effects from current Federal emissions regulations; pending Federal regulations on new source review and greenhouse gas emissions; and any potential transition to alternative technologies. To the extent the proposed project addresses any of these factors they should be discussed, quantified, and aligned with the stated purpose and need. The applicant should include the following information in the ER: • A comprehensive assessment of the existing supply of generating capacity in the service area or power market predicated on the description, conditions, and constraints provided in Section 8.1. The existing supply of generating capacity should be disaggregated by fuel type and by dispatch (baseload, intermediate, peaking). • All known or anticipated power purchases or sales which would serve to affect the net supply of power within the area of interest. • All potential capacity additions, retirements, uprates, and fuel switches for the entire service area. Recognizing not all planned capacity additions will be built and become operational, the applicant should only include “highly likely actions,” that is, projects currently under construction and/or having an issued certification of need from a utility oversight organization (e.g., a state utility commission) for the projected growth in capacity. DG-4026, Page 129 Table 8-2 provides a representative format for displaying the supply of power in a
