Texas Halts 474 GW of Data Center Power Applications, Review Covers Financial and Environmental Impacts
Texas Governor Greg Abbott directed the Texas Public Utility Commission (PUCT) and the Electric Reliability Council of Texas (ERCOT) on August 4 to conduct comprehensive reviews and audits of all data centers applying to connect to the ERCOT grid. Pending the completion of these reviews, the 474 GW of new power demand applications—approximately 90% of which come from AI data centers—will not proceed. This figure exceeds Texas’ historical peak power demand by more than five times, raising concerns about grid stability.
Under Abbott’s directive, PUCT and ERCOT will require each data center project to submit detailed information, including whether the project relies on state tax incentives, subsidies, or public funds, and whether developers will bear construction costs. Applicants must also provide estimates of annual and peak power demand, plans for on-site power generation, the methods of power generation, and specific measures to reduce reliance on the ERCOT grid. The review will further assess annual and peak water demand, water supply sources, cooling technologies, noise and light pollution impacts, traffic effects, emergency response plans, and disclosure of project ownership structures.
The Texas state government emphasized that the review aims to ensure grid reliability and the stability of residential power supply. Abbott stated, "Protecting the safety and quality of life of Texas residents is the government’s top priority." Currently, data centers account for 90% of the 474 GW of new power demand applications being processed by ERCOT, far exceeding the grid’s historical load capacity. If all applications were approved, they could pose significant risks to grid stability.
