Texas Grid Operator Sets New Unofficial Peak Demand Record, Issues Weather Watch

The Electric Reliability Council of Texas on July 14 reported that it set a new unofficial July and all-time peak demand record of 81,406 megawatts on July 13, 2023. 

ERCOT’s 6-day Supply and Demand dashboard is showing the possibility of a new all-time peak demand record the week of July 17, it said. The dashboards will update in real-time as the week progresses.

“There is currently enough capacity to meet forecasted demand. Last year, ERCOT set 11 new peak demand records, surpassing 80 GW for the first time ever,” ERCOT said.

ERCOT on July 14 also issued a Weather Watch for July 16–18 due to forecasted higher temperatures, higher electrical demand and the potential for lower reserves.

An ERCOT Weather Watch is an advance notification of forecasted significant weather with high demand. Grid conditions are expected to be normal, but due to forecasted conditions, operating reserves may be lower.

ERCOT said it continues to monitor conditions closely “and will deploy all available tools to manage the grid and will continue our reliability-first approach to operations.”
