Description: This Nodal Protocol Revision Request (NPRR) seeks to improve management of congestion during an Energy Emergency Alert (EEA) by proposing: 1. Language that provides a mechanism for ERCOT Operations to manage constraints in EEA 2 or 3 to higher Facility ratings when applicable for those constraints identified as limiting generation output; and 2. Language that reconsiders use of double-circuit contingencies during emergency operations based on ERCOT Transmission Grid conditions.
Reason: Addresses current operational issues
