This Nodal Operating Guide Revision Request (NOGRR) provides a clearer explanation of the review and analysis performed by a Qualified Scheduling Entity (QSE) related to turbine speed Governor Performance during periods of ERCOT System frequency deviations.  It also changes the term frequency deviations to frequency disturbance events consistent with the scope of the Performance Disturbance Compliance Working Group (PDCWG). [Luminant IA Review, Also review Calpine comments.
·         070NOGRR Synchronization with NPRR356, EEA Changes Related to Dispatch Instructions and BLTs.  This Nodal Operating Guide Revision Request (NOGRR) synchronizes the Nodal Operating Guides with Nodal Protocol Revision Request (NPRR) 356 EEA Changes Related to Dispatch Instructions and BLTs, which changes the need to issue Dispatch Instructions to suspend any ongoing ERCOT-required generating unit or Resource performance testing and moves the requirement to inquire about the availability of Block Load Transfers (BLTs) from Energy Emergency Alert (EEA) Level 2A to EEA Level 2B. [ERCOT] IA Review.
·         071NOGRR Synchronization with NPRR362, Changes to PRC Calculation.  This Nodal Operating Guide Revision Request (NOGRR) synchronizes the Nodal Operating Guides with Nodal Protocol Revision Request (NPRR) 362, Changes to PRC Calculation, which proposes to properly reflect the current Responsive Reserve (RRS) which is supplied from Load Resources into the PRC calculation.  NPRR362 also deletes the method for calculating the PRC from Energy Emergency Alert (EEA) Levels 1 and 2.  [ERCOT] IA Review; Needs to follow NPRR.
·         073NOGRR Entity Responsible for Load Shed During EEA Level 3.  This Nodal Operating Guide Revision Request (NOGRR) clarifies who is responsible to shed Load during an Energy Emergency Alert (EEA) Level 3 event.  This NOGRR also clarifies that ERCOT is responsible for directing Load shedding.

[BSWG] Language Review
·         077NOGRR Synchronization with NPRR379, EILS Dispatch Sequence and Performance Criteria Upgrades. This Nodal Operating Guide Revision Request (NOGRR) synchronizes the Nodal Operating Guides with Nodal Protocol Revision Request (NPRR) 379, EILS Dispatch Sequence and Performance Criteria Upgrades, which provides ERCOT Operators with enhanced flexibility for managing grid conditions during an Energy Emergency Alert (EEA) by requiring dispatch of EILS prior to or in conjunction with dispatch of Load Resources providing Responsive Reserve (RRS) in EEA Level 2.
