On Monday Dec 1st, ERCOT published the 2025 Official Four Coincident Peak (4CP) Intervals and ERCOT wide Peak Demands. These are the intervals that will be used to determine each meter’s individual 4CP demand for the 2026 Transmission Cost Recovery Charges from your Transmission & Distribution Service Provider. Each meter’s instantaneous demand during each of the four intervals below will be averaged together and the resulting number will be the 4CP Demand in KW that will be used by the TDSP to invoice the 2026 Transmission Cost Recovery Charge on the TDSP portion of your invoice.
