NPRRs Referred by WMS NPRR585, Clarification of Administrative Pricing Requirements for Self-Committed Combined Cycle Combustion Turbines on a Resource Committed by RUC – ERCOT clarified that when a CC configuration is RUC’d another GT could be started and the revenue from the new configuration contributes to the RUC guarantee.

NPRRs Referred by WMS NPRR576, Changing Non-Spin Service to an Off-Line Service Discussed the reliability value of Non-Spin. ERCOT needs the reserves.
