The Electric Reliability Council of Texas intends to complete an audit of hundreds of data center proposals by Dec. 10, grid officials said, a step required before its Batch Zero study process can resume and large load interconnections can move forward.
Texas Governor Greg Abbott called for the audit of all data centers in the ERCOT interconnection queue, which prompted the grid operator to delay the Batch Zero review. Interconnection requests in the queue total roughly 474 gigawatts, a figure ERCOT notes is more than five times the record peak electricity demand the grid has ever served.
The scale of that gap is what drove the review. Queue totals include speculative and duplicate applications, and separating projects with financing, land and equipment commitments from placeholder submissions determines how much load the grid actually needs to plan around.
The pause carries consequences beyond Texas. BloombergNEF analysis found the interconnection halt puts about 20% of the total US data center pipeline at risk of delay, reflecting how much of national capacity growth had been routed toward the ERCOT footprint.
Other states have taken different approaches to the same demand pressure. Pennsylvania will grant data center projects preferential permitting treatment if they commit to specified power supply, environmental and cost responsibility conditions, requiring projects to source electricity from new supply including firm clean generation to qualify for faster review.
Utilities across the country continue to promote their data center pipelines while contending with equipment backlogs and public opposition, which has led analysts to question execution and cost recovery.
