Background

Status: Approved
Date Posted: Jul 26, 2017
Sponsor: ERCOT
Urgent: No
Sections: 3.2.3 and 3.2.5
Description: This Nodal Protocol Revision Request (NPRR) addresses four separate reporting items in Section 3, Management Activities for the ERCOT System, of the Nodal Protocols. 1. This NPRR makes changes to the logic for the Short-Term System Adequacy Reports for more consistent treatment of Resource Statuses in reporting available capacity. Also, more specific language is added to provide clarity to end users of the reports. 2. This NPRR creates a new report which will show the portion of Ancillary Service Offers at or above 50 times the Fuel Index Price (FIP) when the Market Clearing Price for Capacity (MCPC) of that Ancillary Service exceeds 50 times FIP. This posting will occur seven days after the Operating Day, as required by P.U.C. SUBST. R. 25.505, Resource Adequacy in the Electric Reliability Council of Texas Power Region. 3. Additional elements are added to the “48-Hour Highest Price AS Offer Selected” report to also include the highest-priced Ancillary Service Offer selected in a Supplemental Ancillary Services Market (SASM). 4. A 60-day SASM disclosure report is created to provide transparency into Ancillary Service Offers and awards for any SASMs that may have been executed for a period within an Operating Day.
Reason: Meets Strategic goals; Regulatory requirements
