ermination by evaluating the need for power and the potential benefits of the proposed action and the alternatives. III. REVIEW PROCEDURES If an independent review of need for power is to be conducted by NRC staff in lieu of using a review prepared by affected States and/or regions, the procedures discussed below should be followed. These procedures also may be used by the reviewer as an aid in evaluating forecasts prepared by others. The procedures assume a traditional utility. Industry best practice may evolve in response to deregulation. The reviewer should be aware of, and use, industry best practice where possible. (1) Calculate baseload demand as that portion of forecasted kilowatt-hour (kWh) sales occurring at loads equal to or less than average load. (a) Forecasted growth in the relevant region(s) as a range: ` The forecasted growth rates of kWh sales in this analysis should include at least the applicant’s mid-range, high, low, 75th percentile, and 25th percentile forecasts, and the forecast ranges developed by the affected State and/or region or NRC staff (ESRP 8.2.1). ` If the range of reasonable forecasts developed or adopted by the staff (the 25th percentile to 75th percentile range) includes the applicant’s forecasts of the 25th to 75th percentile range, perform the analysis using the NRC range. ` If the range of relevant regional forecasts developed or adopted by the NRC staff is included in the applicant’s 25th percentile to 75th percentile range, perform the analysis using the applicant’s range. ` If the two ranges partially overlap or one is lower, use the lower of the two ranges. (b) In any case, analyze (a) Reserves are defined in this ESRP as the difference between accredited net generating capacity and peakload responsibility; the reserve margin is this difference divided by the peakload responsibility. (b) For each growth rate used, calculate system peakload for the relevant years and adjust for firm purchases and sales and
