NPRR377 Alternate Inputs to Base Point Deviation Charge

Approved sponsor ERCOT posted 2011-06-07 ercot.com

Summary

This Nodal Protocol Revision Request (NPRR) will align the Adjusted Aggregated Base Points (AABP) formula with the inputs to the Generation Resource Energy Deployment Performance (GREDP) measure. The current formula for AABP inaccurately assesses Base Point Deviation charges for under and over generation when shortened Security-Constrained Economic Dispatch (SCED) intervals occur. Additionally, this NPRR includes bill determinants to track the over and under generated volumes and correct language for bill determinants P1 and P2.
