The Planning Reserve Margin Requirement (PRMR) is the number of Zonal Resource Credits (ZRCs) required to meet an LSE’s Resource Adequacy Requirements (RAR). The RAR is established to ensure that LSEs have enough Planning Resources to reliably serve load.  


LSEs that have a PRMR will be obligated to procure capacity equal to their PRMR pursuant to the relevant Auction Clearing Price (ACP) for the Local Resource Zone (LRZ) where they have PRMR unless, and to the extent that, the LSE meets its PRMR via a Fixed Resource Adequacy Plan (FRAP).
