Day-Ahead Operations Process. The Market-Based Operating Entities will execute a day-ahead unit commitment for all of the generators throughout the market footprint. The Market Based Operating Entities will supplement the day-ahead unit commitment with a security constrained economic dispatch tool which uses a network analysis model that mirrors the real-time model found within their state estimators. As such, the day-ahead unit commitment and its associated security constrained economic dispatch respects facility limits and forecasted system constraints. Facility limits of Coordinated Flowgates under the functional control of Market Based Operating Entities and the allocations of all Reciprocal Coordinated Flowgates will be honored. The day-ahead unit commitment and its associated security constrained economic dispatch will be used to establish the Firm Flow Limit of all Coordinated Flowgates.
Day-Ahead Operations Process. Any Market-Based Operating Entity that has a day-ahead market will execute a day- ahead unit commitment for all of the generators throughout the market footprint. MISO’s day-ahead unit commitment uses a network analysis model that mirrors the real-time model found within their state estimators. As such, the day-ahead commitment respects facility limits and forecasted system constraints. SPP’s design of a day-ahead market is uncertain at this time.
Day-Ahead Operations Process. The Market-Based Operating Entities will use a day-ahead operations process to establish the Firm Flow Limit on Coordinated Flowgates. If the Market-Based Operating Entities utilize a day-ahead unit commitment, they will supplement the day-ahead unit commitment with a security constrained economic dispatch tool, which uses a network analysis model that mirrors the real-time model found within their state estimators. As such, the day-ahead unit commitment and its associated Security Constrained Economic Dispatch respects facility limits and forecasted system constraints. Facility limits of Coordinated Flowgates under the functional control of Market-Based Operating Entities and the allocations of all Reciprocal Coordinated Flowgates will be honored. For Coordinated Flowgates, a Market-Based Operating Entity can only use one of the following two methods to establish Firm Flow Limit. A Market-Based Operating Entity must use either the day-ahead unit commitment and its associated Security Constrained Economic Dispatch, or a Market-Based Operating Entity's GTL and unused Firm Transmission Service impacts, up to the Flowgate Limit, on the Coordinated Flowgate. At any given time, a Market Based Operating Entity must use only one method for all Coordinated Flowgates and must give ninety days notice to all other Reciprocal Entities, if it decides to switch from one method to the other method. On a case by case basis, with agreement by all Reciprocal Entities the ninety-day notice period may be waived.
