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 or “PRM” means a percentage of the capacity over and above the peak demand as may be prescribed by Authority or approved by the Commission from time to time for the purpose of generation resource planning.

More Definitions of Planning Reserve Margin

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.

Planning Reserve Margin means an increment of supply needed to meet conditions of high demand in excess of the applicable peak load forecast and other conditions such as higher resource outages, or lower availability of resources, expressed as a percentage of the applicable peak load forecast.

Planning Reserve Margin or “PRM” means a specified percentage of peak load forecast of the system as may be stipulated by the Authority for the purpose of generation resource planning to address the demand and supply variation ensuring adequacy of generation resources in the system.
