Texas Puts Data Centers on Notice as Grid Queue Swells
Texas built its reputation as a welcoming home for data centers on cheap power and light-touch regulation. Now, as proposed projects pile into the grid queue, the state is putting a checkpoint in front of the industry’s next expansion.

On Monday, Gov. Greg Abbott directed the Public Utility Commission of Texas and ERCOT, the state’s main grid operator, to verify and audit new data-center proposals before they connect. His stated aim is to “keep the grid stable and reliable.”

The order follows a sharp acceleration in ERCOT’s interconnection backlog. The queue stood at 233 gigawatts in January; within less than six months it had risen to 474 gigawatts, more than five times the system’s record peak demand. ERCOT says data centers account for roughly 90% of those requests, although many remain early-stage paper proposals that may never be built.

The new reviews demand more than a power estimate. Developers must disclose expected on- and off-site electricity use, water consumption and sourcing, tax incentives, ownership details, and plans to limit noise and light while tracking effects on nearby communities. The governor had first sought such information through a voluntary survey; most companies did not respond, prompting the mandatory approach.

The state’s calculation is not simply anti-growth. Texas has added major wind and solar capacity while retaining the natural-gas resources that helped lure Google, Microsoft and other operators. But rising electricity prices, pressure from data centers and crypto mining, and the sheer size of the queue have turned what was once a development advantage into a reliability test.

The audit’s duration—and its practical bite—remain unclear. Some facilities can generate their own power, while areas including El Paso sit outside ERCOT. Still, with at least 335 data centers already operating in Texas and 248 more planned, the order signals that the state’s data-center boom will no longer get an automatic pass.
