staff analysis, calculate peakload responsibility based on forecasted growth rates for peakload demand. (a) Determine these by contrasting the applicant’s projected range of growth rates for system peakload with the range of growth rates developed or adopted by the staff for the system peak. The same rules for comparison apply as for annual kWh sales: (a) Peakload responsibility is defined as system load plus firm sales and less firm purchases. NUREG-1555 8.4-6 October 1999 Reserve Margin  Accredited Generating Capacity  Peakload Responsibility Peakload Responsibility ` If the range of reasonable forecasts developed or adopted by the staff includes the applicant’s forecast, the reviewer should perform the analysis using the developed or adopted forecast. ` If the range of forecasts falls totally below the applicant’s forecast, the reviewer should use the staff forecasts. (8) For each estimate of peakload responsibility(a) and for each year under consideration, calculate reserve margin as Based on the reserve margins and the projections for baseload demand, determine the timespan representing the probable dates when plant capacity will initially be needed. (9) Prepare an analysis of the costs and benefits of not having sufficient and timely capacity additions and also the costs and benefits of adding capacity too soon. (a) For these purposes, assume the applicant’s proposed date of commercial operation of all proposed units and consider the effects of the load materializing 3 years earlier than this date and 3 years later than this date. (b) The 6-year timespan may be shifted if conditions specific to the service area suggest this to be appropriate. Treatment of this subject should include, at a minimum, participation by the socioeconomic and benefit-cost reviewers. (10) If a need-for-power analysis conducted by or for one or more relevant regions affected by the proposed plant concludes there is a need for new generating capacity, that finding should be
