ERCOT: Data centers cause Texas' large load queue to balloon

The Electric Reliability Council of Texas (ERCOT) has seen a dramatic increase in large load interconnection requests, with the queue ballooning by nearly 150 gigawatts to 410 gigawatts in just two weeks. Approximately 87% of these requests come from data centers, reflecting Texas's emergence as a major hub for the high-tech industry. ERCOT officials, including President and CEO Pablo Vegas, discussed this massive uptick at their third annual Innovation Summit at Kalahari Resorts' convention center in Round Rock. Vegas noted the rapid evolution of the Texas grid and energy market, stating that the grid today is vastly different from even five years ago. ERCOT's all-time peak demand was 85 GW in August 2023, while projected peak demand could reach 145 GW by 2030. Vegas attributed the recent "significant jump in projects" to a backlog of requests from Oncor that entered the queue simultaneously. The agency is also shifting to a Batch Study framework for large load interconnection, requiring hyperscalers and other large energy users to be included in stability and reliability assessments before energizing. This move comes as data centers increasingly adopt a "bring your own generation" approach, though the uncertainty of regional build-out means some projects may not materialize.
