Overview
Updated 1 hour agoFor years, plugging a big new customer into the Texas power grid ran on a first-come, first-served basis. On August 20, state regulators told the grid operator to screen those customers first.
The trigger is scale. Requests to connect now total about 474 gigawatts, more than five times the grid's record demand, and roughly 90% come from data centers built for artificial-intelligence computing. Most of that power does not exist yet.
Why it matters
Texas closed the open door to its power grid; data centers powering the AI boom must now pass an audit before they can plug in.

Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
Winter Storm Uri and the ERCOT collapse (2021)
A deep freeze knocked out much of Texas power generation. ERCOT ordered rolling blackouts that left millions without heat for days, and hundreds died. The grid came minutes from a much longer, uncontrolled collapse.
The PUCT's chair and ERCOT's CEO resigned, and the legislature passed a package of grid reforms.
Reliability became the dominant test for any grid decision in Texas, giving regulators political cover to act aggressively.
Uri is why Texas officials now treat huge new loads as a reliability question first. The audit reflects a grid still wary of promising power it may not have.
Dominion pauses Virginia data-center hookups (2022)
In Loudoun County, home to the world's densest cluster of data centers, utility Dominion Energy warned it could not connect some new projects because transmission in the area was constrained. The pause rattled the industry.
Dominion accelerated transmission upgrades and connections resumed within months.
It was an early signal that data-center growth could outrun grid capacity, forcing utilities to ration access.
Virginia showed the same collision now hitting Texas, but on a smaller scale. Texas is confronting it before wires are strung, not after.
FERC overhauls the interconnection queue (2023)
Federal regulators issued Order 2023 to fix clogged national queues where speculative projects tied up study resources for years. The rules added deposits and readiness tests to force out projects that would never get built.
Grid operators began restudying queues and imposing stricter entry requirements.
It set a template: use verification and financial commitment to separate real projects from placeholders.
Texas is applying that same logic to demand. The 474 GW figure looks like a queue padded with speculative requests, and the audit is the filter.
