Background

Status: Approved
Date Posted: Aug 30, 2022
Sponsor: ERCOT
Urgent: No
Sections: 4.4.7.2.1, 6.5.7.3.1, and 6.5.7.6.2.4
Description: This NPRR addresses Protocol gaps found during the creation of the ECRS system change requirements. Specific changes include: Language was added to Section 4.4.7.2.1 to align NPRR863, Creation of ERCOT Contingency Reserve Service and Revisions to Responsive Reserve, implementation to a pre-Real-Time Co-Optimization (RTC) system design. Clarification was added about simultaneous awarding and Real-Time provision of Responsive Reserve (RRS), ECRS, and Non-Spinning Reserve (Non-Spin) by Load Resources that are not Controllable Load Resources; Language was added to paragraph (1) of Section 6.5.7.6.2.4 to clarify that ECRS will also be deployed to provide energy upon detection of insufficient available capacity for net load ramps. (Such use is in addition to the uses already included in the Protocols: use for frequency restoration, energy during an Energy Emergency Alert (EEA), or as a backup to Regulation Up Service (Reg-Up)); and Language was added to paragraph (2)(e) of Section 6.5.7.3.1 to clarify that ECRS deployments from Load Resources that are not Controllable Load Resources will be considered at a ten-minute linear ramp for the calculation of the Real-Time On-Line Reliability Deployment Price Adder. This is similar to the approach taken with RRS deployments from Load Resources that are not Controllable Load Resources.
Reason: Market efficiencies or enhancements
