Description: This NPRR would remove the ability to bid for CRRs in the CRR auction or bid for PTP Obligations in the DAM that exist entirely within a station. For the DAM, the implementation would be in two phases: (1) Initial implementation phase where ERCOT manually posts the disallowed Electrically Similar Settlement Points, and programmatically removes those transactions before running the DAM; and (2) Phase after system implementation for automated posting of Electrically Similar Settlement Points built from the 0600 DAM study (supporting Power System Simulator for Engineering (PSS/E) file postings in NPRR290, ERCOT Publication of DAM PSS/E Files) -- the DAM solution engine would not award those transactions inclusive of any outages received by 1000 -- and automated post-DAM disclosure of the final list of Electrically Similar Settlement Points applicable to the DAM solution. As such, the DAM language contains grey-boxed language to clarify how this would be handled in the two different phases. For CRRs, the implementation for disallowing PTP Obligation bids for Electrically Similar Settlement Points would be in two phases: (1) Initial implementation phase where ERCOT manually identifies and removes each Electrically Similar Settlement Point PTP Obligation bid submitted to the CRR Auction prior to the market optimizations; and (2) Final implementation phase where the CRR application detects and prevents Electrically Similar Settlement Point PTP Obligation bids when the CRR Auction bid portfolio is entered by the Market Participant.In both implementation phases, ERCOT shall post the Electrically Similar Settlement Points with the CRR Auction Market Notice.
Reason: Certain types of bids and offers have shown to be difficult to value in the CRR Auction and DAM.
