NPRR952  Use of Katy Hub for the Fuel Index Price

This Nodal Protocol Revision Request (NPRR) proposes fully replacing Houston Ship Channel with Katy Hub as the reference for the Fuel Index Price (FIP) for natural gas in ERCOT’s systems. This change is consistent with recent amendments to P.U.C. SUBST. R. 25.505, Resource Adequacy in the Electric Reliability Council of Texas Power Region, adopted by the Public Utility Commission of Texas (PUCT) in Project No. 48721, which give ERCOT flexibility to select an appropriate natural gas price index for the purposes of calculating the Peaker Net Margin (PNM) threshold and the Low System-Wide Offer CAP (LCAP).
