Summary

This Nodal Protocol Revision Request (NPRR) changes the current requirement that any required SSR studies be complete and mitigation be in place prior to Initial Synchronization of a new Generation Resource, Energy Storage Resource (ESR), or Settlement Only Generator (SOG). Based on recognition that SSFR can be a risk upon energization, this NPRR requires that these steps now be completed prior to Initial Energization to ensure that SSFR risk has been evaluated and mitigated.
