Description: This Nodal Protocol Revision Request (NPRR) clarifies the effective Fuel Index Price (FIP) used in market activities executed prior to the publication of the index for the Operating Day. FIP is used by multiple applications, and the current FIP definition does not address the timing around receiving the data and when it can feasibly be used by market applications. Any source for this index that ERCOT selects publicly publishes a methodology regarding effective dates for weekends and holidays and ERCOT will follow that methodology. Therefore, ERCOT removes specific language related to weekends and holidays and defers to the methodology indicated by the source. Additionally, this NPRR incorporates the OBD “System-Wide Offer Cap and Scarcity Pricing Mechanism Methodology” into Protocols.
