This Nodal Protocol Revision Request (NPRR) adds a requirement for ERCOT to post on the Market Information System (MIS): (a) the ERCOT Short-Term Load Forecast (STLF) for the current Security-Constrained Economic Dispatch (SCED); (b) the STLF for the next or prompt five-minute SCED interval; and (c) the STLF effective within 15 minutes. This NPRR also clarifies SCED up/down reserves and adds capacity for the aggregate sum of the High Dispatch Limits (HDLs) and Low Dispatch Limits (LDLs) for the On-Line Generation Resources in each five-minute SCED interval.
This NPRR will provide Market Participants the same data sets (subject to confidentiality provisions) that ERCOT uses within its Real-Time Market (RTM) systems for their use in making commercial and operational decisions and would support any long-term project ERCOT is currently evaluating an RTM upgrade project styled as Real-Time Market for Co-Optimizing Energy & Ancillary Services Combined with Demand Response. In the short term, to facilitate Market Participants’ decision making processes, this NPRR expands the Real-Time posting requirements on the MIS.
