Description: This Nodal Protocol Revision Request (NPRR) clarifies that a Generation Resource or Energy Storage Resource (ESR) may serve Customer Load in any circumstance in which the Customer and the Resource are both disconnected from the ERCOT System due to an Outage of the transmission or distribution system. It is limited to configurations where the Resource and Customer Load are using privately owned transmission and distribution infrastructure during the Private Microgrid Island (PMI) operation. This is not a Private Use Network and the Load and Resource do not net during normal circumstances. For PMIs with an ESR, after the initial Settlement of an Operating Day in which the private microgrid operated as a PMI, this NPRR proposes an adjustment to ensure that consumption by the ESR prior to the PMI operation period and subsequently used to serve the Customer during private microgrid operation is no longer treated as Wholesale Storage Load (WSL). This adjustment will recharacterize the Load from WSL to Non-WSL on an Operating Day basis for as many Operating Days as necessary to ensure that ESR Load not eligible for WSL treatment is not provided WSL treatment.
Reason: Market efficiencies or enhancements
