This Nodal Protocol Revision Request (NPRR) defines the term "fuel adder" as reported by Resource Entities when filing Reliability Must-Run (RMR) contracts. The NPRR also clarifies that the fuel adder will be true-up to reflect actual fuel costs incurred.
Reason:
This NPRR is submitted to ensure accurate fuel prices are used when calculating Three-Part Supply Offers for the Day-Ahead Market (DAM). When a Resource Entity files an RMR contract, it must provide to ERCOT the estimated fuel adder as part of its Eligible Costs submission. This fuel adder is added to the appropriate index price to establish the Three-Part Supply Offers. If the fuel adder is not accurate, it can skew the Three-Part Supply Offers and impact DAM results. After the DAM has cleared, Resource Entities have the option of filing with ERCOT their actual fuel costs prior to the Final or True-up Settlements.
