Peak electricity consumption in Texas could more than quadruple by 2032, according to a new report from the state’s primary grid operator.
The new report, which the Electric Reliability Council of Texas released on April 15, shows peak energy demand in 2032 reaching 367,790 megawatts — an amount far exceeding the Texas grid’s current record of 85,508 megawatts registered in 2023.
But ERCOT officials caution that the new projections almost certainly have missed the mark, and that the demand that eventually shows up likely will be far less. Uncertainty surrounding the future of data center growth from the ongoing artificial intelligence boom is largely driving the grid operator’s planning difficulties.
“Texas is experiencing exceptional growth and development, which is reshaping how large load demand is identified, verified, and incorporated into long-term planning,” ERCOT President and CEO Pablo Vegas said in a written statement, as reported by The Texas Tribune, an online news outlet. “As a result of a changing landscape, we believe this forecast to be higher than expected future load growth.”
ERCOT officials say they continue refining their demand tracking methods, and they plan to file revised projections in the future. But in recent comments to the PUC, ERCOT officials provided no real guidance on possible alternatives, and instead requested to consult with the regulatory agency’s staff on how to proceed.
“I think it’s clear we need to engage in the process to find ways to refine this number into something that’s more usable,” PUCT Chair Thomas Gleeson said during the grid operator’s recent presentation.
Long-Term Load Forecast Details
- In the past, the long-term load forecast fell under the exclusive purview of ERCOT. That changed with Senate Bill 6, which directed the PUC to draft rules overseeing the inclusion into the forecast of large loads. The Commission’s rule adopted at PUC Subst. R. §25.370 requires ERCOT to incorporate large load interconnection requests from Transmission Service Providers where the large load has met a set of financial commitments.
- ERCOT’s long-term load forecast is a key input to various planning tools employed by the grid operator, including the Regional Transmission Plan, and the PUC’s coming assessment of its new Reliability Standard, ERCOT’s Capacity Demand and Reserves report.
- ERCOT eventually trimmed the large-load interconnection projections it released last year by approximately 75 percent. The gird operator made the changes based on its observations of the historical pace of interconnections.
- The influx of expected large-load demand — whether its 367,790 MW or something less — has led ERCOT to pursue the development of a new process whereby it considers multiple interconnection requests gathered in annual batches. That development process remains ongoing. See separate story here.
