Texas Freezes a 474-Gigawatt Grid Connection Queue That Is Almost Entirely Data Centers

The Electric Reliability Council of Texas (ERCOT) is holding more than 474 gigawatts of interconnection requests, about 90 percent of them from data centers. Utility Dive reports that figure is more than five times the grid's record peak demand. On August 3, Governor Greg Abbott ordered an audit of every data center in the queue, and the Public Utility Commission of Texas and ERCOT must complete it before any project can move forward.

The audit asks four questions that show what the state is actually worried about: whether a project brings its own power generation or depends on the grid, how much water it uses, and which developers are claiming state or federal tax incentives, grants or abatements. That is a filter aimed at speculative queue positions. Developers have an incentive to file interconnection requests at many sites and decide later, which inflates the queue and makes planning harder for everyone behind them.

BloombergNEF estimates the pause puts about 20 percent of the total United States data center pipeline at risk of delay. Law firms advising developers note that the order disrupts projects already under construction and contracts written on the assumption that interconnection would proceed, which creates real uncertainty over those parties' contractual obligations. Texas is not acting alone. New York halted new data center approvals in July for up to a year while it writes development rules.

Texas has been the default choice for new United States AI capacity because of fast permitting, cheap land and abundant natural gas. That advantage now carries a queue-position risk that did not exist a month ago. The Telegram channel AI Post described the figure as a ban on more than 1,800 data centers, which overstates the actual legal mechanism. The state has not cancelled any projects. It has paused new approvals until the audit determines what the queue actually contains.
