NPRR #434 · Revision Request
NPRR434 Increase the Capacity Limitation of a Generation Resource Providing RRS
ReasonThis revision is required due to the changes in the ERCOT Methodologies for Determining Ancillary Services Requirements of moving 500 MW of Non-Spinning Reserve (Non-Spin) Service to RRS. That change could require additional Generation Resources to provide the service and to be On-Line in Real-Time. This could raise the Market Clearing Price for Capacity (MCPC) of RRS and suppress Real-Time Locational Marginal Prices (LMPs).
