ERCOT targets December completion of data center interconnection audit
Utility Dive Surfaced Read the original
ERCOT is working to complete a governor-mandated audit of data center interconnection requests by December, an effort tied to a current pause on new data center interconnections in Texas. Officials said Thursday that the audit could affect ERCOT's upcoming long-term load forecast and reliability assessment, both of which feed directly into transmission and generation adequacy planning. The audit's scope and findings have not yet been finalized, and its outcome will determine how large-load data center demand is treated in future ERCOT planning cycles.

「Background」 ERCOT has been fielding an unprecedented pipeline of data center interconnection requests as Texas load growth forecasts have surged, prompting concern about speculative or duplicate projects clogging the queue and distorting reliability planning. On August 3, 2026, Governor Greg Abbott directed the Public Utility Commission of Texas and ERCOT to conduct a comprehensive verification and audit of data center projects moving through the interconnection process, and ERCOT paused new data center interconnections in response, with reporting indicating up to 300 projects, mostly data center proposals, are subject to review.
「What this means for grid operators」 ERCOT's transmission planning and resource adequacy teams should treat current data center load projections as provisional until the audit concludes, since the results may revise the queue of interconnection requests used in the long-term forecast. Generation developers and large-load customers seeking interconnection in ERCOT territory should expect continued uncertainty on timelines while the pause remains in effect, and should build contingency into project schedules that assumed near-term approval. Utilities and co-located industrial load owners planning around ERCOT capacity should hold off on finalizing capital commitments tied to specific interconnection dates until the audit's findings and any resulting queue changes are published.
「What stands in the way」 The audit outcome depends on data still being compiled from interconnection applicants, and any resulting changes to interconnection procedures would likely require Public Utility Commission of Texas approval before taking effect.
