Background

Status: Pending
Date Posted: Apr 29, 2025
Sponsor: ERCOT
Urgent: Pending
Sections: 2.2, 5.5.2, 8.1.1.2.1.1, 8.1.1.2.1.2, 8.1.1.2.1.3, 8.1.1.3.1, 8.1.1.3.2, and 8.1.1.3.4
Description: This Nodal Protocol Revision Request (NPRR) makes changes to the duration requirements for the following Ancillary Services in preparation for Real-Time Co-optimization plus Batteries (RTC+B): Updates duration requirements for Regulation Service and Responsive Reserve (RRS) to thirty minutes; and updates duration requirement for ERCOT Contingency Reserve Service (ECRS) to one hour. This NPRR also updates the requirement for Reliability Unit Commitment (RUC) studies to use a one-hour duration for all Ancillary Service types, excluding Fast Frequency Response (FFR). The changes proposed in this NPRR have no system impacts because these Ancillary Service durations are being incorporated as parameters in the current RTC+B business requirements.
Reason: General system and/or process improvement(s)
