Summary
This Nodal Protocol Revision Request (NPRR) corrects an error in the calculation of Real-Time Reliability Deployment Price Adders for Ancillary Services when ERCOT is directing firm Load shed during Energy Emergency Alert (EEA) Level 3 under the RTC+B Protocol language. These proposed changes replace the “maximum value on the ASDC for the Ancillary Service” in paragraph (2)(t) of Section 6.5.7.3.1 with the effective Value of Lost Load (VOLL) for determining the price adders for Ancillary Services, ensuring that final Ancillary Service prices cannot exceed $5,000 per MWh.
