Description: This Nodal Protocol Revision Request (NPRR) implements several improvements to Firm Fuel Supply Service (FFSS). Specific changes include: amending the definition of an Availability Plan to include a requirement that, in cases where a Resource is required to have a submitted Availability Plan and has a change in availability, the Availability Plan must be updated within 60 minutes of that change in availability; adding more detailed direction to incorporate the concept of having an alternate Generation Resource that may be designated to become the FFSS Resource (FFSSR) in providing FFSS; adding a requirement for ERCOT to post a disclosure report of FFSS offers after each procurement period, in alignment with the expiration of confidentiality captured in the first FFSS Request for Proposal (RFP); clarifying language regarding procedures for communication between ERCOT and Qualified Scheduling Entities (QSEs) regarding restocking of fuel post deployment of FFSS; changing the directive for ERCOT to report to the Technical Advisory Committee (TAC) at the end of the obligation period (March 15) if deployment(s) occurred instead of within 45 days of each deployment; incorporating requirements for FFSS that were previously only captured in the FFSS RFP; enhancing language and processes around the qualification process, including moving the obligation to test prospective FFSSRs (both primary or alternate Generation Resources) to be prior to the FFSS procurement process. Results from this test will then be used to limit the MW quantity that the QSE can offer for that Resource into the FFSS procurement process; and introducing language and processes for disqualification and decertification of a generator in being an FFSSR, including a process for remediation and recertification.
Reason: Addresses current operational issues
