Texas data centers are hitting grid capacity constraints as AI infrastructure demand outpaces available power supply, forcing industry reassessment of site selection strategy.

Texas is aggressively pursuing the construction of AI data centers, but a critical infrastructure problem is threatening to derail the plans: the state's power grid lacks the capacity to support them.

Governor Greg Abbott announced a moratorium on new data center approvals on Monday. Rather than responding to mounting bipartisan opposition, Abbott's stated goal was to give regulators time to audit how new data centers could connect to the Texas grid without overwhelming it. "Our top priority is to protect Texans' safety and quality of life," Abbott said in a statement.

The scale of the proposed buildout is staggering. The Electric Reliability Council of Texas (ERCOT) has a queue of over 1,800 projects seeking more than 474 gigawatts of electricity—over five times the grid's record peak demand.

The announcement underscores the collision between Texas's ambitions and the practical constraints facing the state. Even before the AI boom, the grid has struggled during unusually cold winters and has been stressed by major cryptocurrency mining operations. New York has already responded by imposing the country's first statewide data center ban.

The lack of transparency has compounded the challenge. The public and state officials have little visibility into which companies are applying to build data centers or how many approvals are pending. News reports estimate at least 335 existing data centers in Texas and at least 248 planned ones, with hundreds more in earlier development stages awaiting grid connection approval.

Many existing facilities bypass the grid entirely by using on-site diesel generators and other power generation methods. Opposition to further buildouts continues to mount, driven by concerns over spiking electricity prices, water depletion, noise pollution, and emissions. Abbott's audit was spurred in part by reports that some data centers failed to comply with a regulator survey on water and power usage. According to Texas state representative Brad Buckley, only 28 of 377 companies surveyed by the Public Utility Commission of Texas responded—a response he characterized as "pretty pathetic."
