NOTICE DATE: August 1, 2024

NOTICE TYPE: M-B080124-01 Operations

SHORT DESCRIPTION: 4-CP Peak Determination 

INTENDED AUDIENCE: All Market Participants

DAYS AFFECTED: August 1, 2024

LONG DESCRIPTION: As discussed at the ERCOT TAC meeting on July 31, 2024, under agenda item 14, 4-CP Update, Market Participants should recognize that the Real-Time operational Load includes Wholesale Storage Load (WSL) while it is excluded from the Settlement 4-CP peak determination calculation pursuant to Protocol Section 9.17.1.  ERCOT uses the four 4-CP peak intervals to determine DSP level average 4-CP load ratio shares which are used by the PUCT in the allocation of Transmission Cost of Service for the ERCOT Region.

Market Participants wanting to monitor potential 4-CP peak dates/times in near Real-Time may want to incorporate the ESR Charging Component of the Energy Storage Resource dashboard (which is equivalent to WSL) into their current monitoring process to align their data more closely with the Settlement 4-CP peak determination calculation.
