Description: This Nodal Protocol Revision Request (NPRR) revises the Real-Time Liability Extrapolated (RTLE) and Day-Ahead Liability Extrapolated (DALE) factors used in the Counter-Party Estimated Aggregate Liability (EAL) and Minimum Current Exposure (MCE) calculations to use electricity futures mark-to-market prices for estimating forward risk. Forward adjustment factors for Real-Time Market (RTM) exposure and Day-Ahead Market (DAM) exposure are calculated using a ratio of futures average price to historic average price of a reference hub. Limits can be set so that forward adjustment factors would fall in a specified range by using a set of parameters. The parameters could be updated through stakeholder review and approval process.
Reason: Market efficiencies or enhancements; Administrative
