ce area’s future need for power. However, while a discussion of need for power is required, the Commission is not looking for burdensome attempts by the applicant to precisely identify future market conditions and energy demand, or to develop detailed analyses of system generating assets, costs of production, capital replacement ratios, and the like in order to establish with certainty that the construction and operation of a nuclear power plant is the most economical alternative for generation of power. The applicant should specify whether it intends to operate the proposed plant as a baseload generator, and, if so, include a discussion of the need for new baseload capacity. The applicant should explicitly state a feasible future date for commencement of full commercial operation of the proposed project. The need for power analysis in the ER should include annual hourly peak (summer or winter, whichever is greater) and baseload demand, and total and baseload supply. The analysis should provide information over sufficient historic and projected periods to permit the staff to complete an independent assessment of the need for the power to be provided by the proposed project. The historic data should include sufficient years to identify any trends or anomalous factors that could affect the future demand for electricity. The projected period should include information out to three years beyond the planned commencement of full commercial operation of the project (referred to herein as “the analytical year”). The following sections describe the need for power analysis process in greater detail, including information needed to adequately describe the power system, power demand, power supply, and the process for assessing the need for power of the proposed project. The applicant should identify all sources of data used in the need for power analysis in the ER and demonstrate how the data upon which the analysis relies was used. For the U.S. Nuclear Regulatory
