| Description: | This Other Binding Document Revision Request (OBDRR) aligns the language in the Procedure for Calculating Responsive Reserve (RRS) Limits for Individual Resources with the Protocols following Phase 1 implementation of Nodal Protocol Revision Request (NPRR) 863, Creation of ERCOT Contingency Reserve Service and Revisions to Responsive Reserve, and corrects inadvertent errors in the formulae for calculating droop performance to determine Responsive Reserve (RRS) limits. The Performance, Disturbance, Compliance Working Group (PDCWG) reviewed these updates at their April 15, 2020 WebEx-only meeting. Listed below is a summary of the modifications that are being proposed by this OBDRR: a) Recognize that any Generation Resource capable of operating in synchronous condenser fast-response mode can provide RRS; b) Clarify RRS limits applicable to Resources providing RRS as Fast Frequency Response (FFR); and c) Correct inadvertent errors in the formulae for calculating droop performance to determine RRS limits. |
