Background

Status: Approved
Date Posted: Dec 27, 2011
Sponsor: Robert Helton on behalf of the Reliability Deployment Task Force
Urgent: Yes
Sections: 3.16 and 3.18
Description: This Nodal Protocol Revision Request (NPRR) increases the amount of Responsive Reserve (RRS) that can be supplied by a Generation Resource to 24%.
Reason: This 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).
