SCED Competitive Constraint Test (CCT) Update Review of (8/1/2013 to 10/8/2013) Market Analysis ERCOT
Background of NPRR 520 (SCED CCT) • Why Change? • SCED over-mitigation issues • What Changed? • No Monthly and Daily Constraint Competitiveness Test (CCT) • SCED CCT runs every 5 minutes (or whenever SCED is executed) • Less set of Resources get mitigated • Minimizing unnecessary Base Point oscillations/QSGR dispatch CMWG
