LONG DESCRIPTION:  On March 17, 2021, ERCOT informed Market Participants that RTM prices for OD February 15, 2021 were impacted by a software error affecting the calculation of Real-Time On-Line Reliability Deployment Price Adders (RTORDPAs).  ERCOT also notified Market Participants that ERCOT would be seeking ERCOT Board of Directors (Board) review of RTM prices for that OD.  See Market Notice M-C031721-01.
