NPRR807  Day-Ahead Market Price Correction

This Nodal Protocol Revision Request (NPRR) clarifies that price corrections will only be performed for the Day-Ahead Market (DAM) in the case where awards are not affected by the error (e.g., a correction at a logical combined cycle resource node where the generator did not participate in DAM). When both prices and awards are affected by an error, a price correction would cause price/dispatch inconsistency, and there is no mechanism under the Protocols to make Market Participants whole to their DAM bids and offers. In these situations, ERCOT proposes that published prices and awards be final to provide market certainty, as Market Participants begin making Real-Time decisions based on DAM results prior to the opportunity for price correction to occur.
