Planning Reserve Margin definition

Planning Reserve Margin or “PRM” means a specified percentage of available capacity above peak demand as may be stipulated by Authority or Commission for the purpose of generation resource planning.

Planning Reserve Margin means the minimum percentage that a Load-Serving Entity’s aggregate Capacity must be above the Load-Serving Entity’s peak kW load, which percentage is defined in the SPP Tariff and as of the Effective Date is twelve percent (12%). For example, if an Load-Serving Entity’s peak kW load were one hundred (100) kW, then the Load-Serving Entity’s aggregate Capacity would need to be at least one hundred and twelve (112) kW so that SPP’s Planning Reserve Margin requirement of at least twelve percent (12%) would be met by the Load- Serving Entity.

Planning Reserve Margin means the difference between the public utility’s expected annual peak existing capacity plus any planned additional capacity and the public utility’s expected annual peak demand, expressed as a percentage of the annual peak demand. In this subsection, “public utility’s expected annual peak demand” includes the expected peak demand of its native custom- ers, less any interruptible sales to native customers, plus any firm power sales under contract.
