Pumped storage projects, like all other projects, are analyzed by comparing the total system costs for a system including the pumped storage project and for a system including an alternative. All possible alternatives must be considered. The alternatives must provide capacity such that the level of risk of failure to meet load demands is the same as that of the system including the proposed project. All other factors must be consistent for the proposal and its alternative. The timing of a pumped storage project requires examination, because the percentage of peaking capacity in a given system has a marked effect on the required reservoir size and on the energy penalties associated with pumped storage. Problems of timing are inter-related with changes in the size of the system within which the pumped storage facility will be used, but such changes require recognition of transmission costs and of the competition of other peaking facilities.
