od sufficient to illustrate any current trends or anomalies that affect future projections of electricity demand; • current (as close to the application year as practicable) peak demand and baseload demand for all sectors; and • future projections of peak demand and baseload demand, extending to the analytical year. Demand Side Management (DSM) and Energy Efficiency (EE) programs affect demand primarily through reductions of peak and intermediate load. Any future DSM or EE should be included in the applicant’s demand forecast as a reduction from annual hourly peak demand. For the purposes of a need for power analysis, the NRC staff considers reserve requirements to be a component of electricity demand; therefore, these should be included and quantified by the applicant as part of demand. DG-4026, Page 128 Table 8-1 provides a representative format for displaying the changes in baseload and annual peak hourly electricity demand components over the temporal scope of the analysis, noting that the analysis is not necessarily bound or limited to only these data points. Table 8-1. Demand Forecast Summary (MW(e)) 20WW(a) … 20WW 20XX(b) 20YY(c) … 20YY 20ZZ(d) Total Baseload Demand Peak Hourly System Demand MINUS: DSM(e) and EE(f) Total Peak Demand PLUS: Reserve Margin Total System Demand – 20WW denotes data years before submittal of the application – 20XX denotes the year of submittal of the application – 20YY represents the intervening years in some useful increment – 20ZZ indicates the year three years after commencement of full commercial operations – DSM is Demand Side Management – EE is Energy Efficiency 8.3 Power Supply The intent of the power-supply section is to fully disclose current and forecast supply of electricity (i.e., capacity), including 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
