AUSTIN, Texas—The state that spent years inviting the world’s data centers to plug in has told the next ones to wait.
Texas has become the first state to freeze new grid connections for data centers, with Gov. Greg Abbott ordering the operator of the state’s main power grid to stop approving requests and audit the projects already waiting in line, according to a letter the governor sent and to Reuters, which reported the move Tuesday. The order targets a queue that has ballooned beyond anything the grid could physically serve.
The numbers are startling even for an industry accustomed to scale. More than 1,400 data-center projects are waiting for grid connections, and together they have requested 474 gigawatts of power—nearly as much electricity as every household in the United States uses, and several times the peak demand the Texas grid has ever been asked to meet. Mr. Abbott warned in his letter that projects of that scale could endanger the reliability and stability of the grid.
The freeze makes Texas an early test of a question spreading across the country: how much of the AI boom’s demand for electricity is real, and how much is speculation dressed up as a data center? The governor asked ERCOT, the Electric Reliability Council of Texas, to determine which projects reflect genuine computing needs and which are claims on capacity made by developers who may never build.
The state’s electricity market made this moment possible. Texas deregulated its grid decades ago, and ERCOT was designed to connect large users quickly, with fewer of the studies and approvals that slow hookups elsewhere. Cheap land, abundant wind and solar, and the absence of a state income tax drew data centers first, then cryptocurrency miners, then the cloud giants and AI labs that now lease power in gigawatt blocks.
The queue became a speculative asset along the way. Developers announced projects, reserved capacity, and sometimes sold the sites or the place in line before breaking ground. Utilities and grid operators began to suspect that a large share of the requests were paper placeholders, options on power rather than plans to consume it. The audit Mr. Abbott ordered is meant to separate the two, and it could lead ERCOT to require deposits, proof of financing, or evidence of real progress before projects keep their place in line.
The reliability fears behind the freeze are not new to Texas. The grid failed catastrophically during the 2021 winter storm, when power outages left millions in the dark, and the state has spent years hardening the system and adding generation since. ERCOT has repeatedly warned that demand growth is outpacing the construction of new power plants and transmission lines, and data-center requests have made the warning acute: a single large facility can draw as much power as a small city.
The mismatch is also a problem of time. Building a power plant or a transmission line takes years, while an AI cluster wants electricity within months of breaking ground. The projects queued in Texas would require a build-out of generation larger than anything the state has ever constructed, on a timeline the industry has not demonstrated it can meet.
The freeze will sort winners and losers. Developers who have real customers, financing, and construction plans can wait out the audit and are likely to keep their projects, though possibly under stricter rules. Speculators who reserved capacity without the means to build will find their place in line less valuable, and some projects may relocate to states where connections are still available. The hyperscalers with the deepest pockets are best positioned to survive the pause.
Politics made the decision notable. Mr. Abbott is one of the most business-friendly governors in the country and has championed Texas as the natural home for the AI economy; a freeze on new connections is a concession that even the state most eager for growth cannot ignore the physics of its grid. He has also pressed for new gas-fired generation and faster transmission construction, measures meant to expand the grid’s capacity while the audit proceeds.
Texas is not alone in wrestling with the problem. Virginia, the largest data-center market in the country, has debated how much new demand its utilities can absorb, and grid operators from the Midwest to California have watched their interconnection queues swell with requests from AI projects. What sets Texas apart is that it acted first, converting a growing worry into a formal stop on new hookups.
For the AI industry, the order is the first hard constraint imposed from outside. Chip orders, model releases, and capital commitments have defined the pace of the boom so far; now a state regulator has said the queue is full. The projects that survive will be the ones that can prove they are real, and the build-out of AI will proceed at the speed of transformers and transmission lines rather than the speed of silicon. Texas has decided to find out which projects deserve the power—and which were never going to draw it.
