Description: This Nodal Protocol Revision Request (NPRR) introduces a Fuel Index Price for Resource (FIPRr). Resources may designate an FIPRr based on the Gas Daily’s Waha index price, or the weighted price of the Gas Daily Houston Ship Channel index price and the Gas Daily Waha index price. The default FIPRr shall be the Fuel Index Price (FIP). Resources that designate an FIPRr based on Waha index price or the weighted price must submit documentation to ERCOT indicating such designation and provide proof of physical delivery from such areas, as described in the Verifiable Cost Manual. In addition, a Real-Time Make-Whole Payment provision is included to address exceptional fuel cost events that are not resolved by the change to an FIPRr.
Reason: Addresses current operational issues Market efficiencies or enhancements Other: Provides for an FIPRr that more accurately reflects a Resource’s actual fuel cost; and allows recovery whenever Resources are mitigated below their actual cost due to exceptional fuel costs.
