Texas Governor Greg Abbott has ordered an audit of every data center project sitting in ERCOT’s interconnection queue, prompting the grid operator to halt its Batch Zero review process while it assesses nearly 474 gigawatts of pending connection requests — a volume roughly equivalent to 40 percent of the entire U.S. generating fleet. The pause signals growing alarm over whether the state’s isolated grid can absorb the explosive demand from AI and cloud computing facilities without compromising reliability or raising costs for residential and industrial customers.
ERCOT’s interconnection queue has ballooned faster than any other in the nation, driven by a combination of generous tax incentives, abundant land, and a deregulated market that allows large loads to connect with minimal upfront transmission commitments. The 474 GW figure dwarfs the grid’s current peak demand of roughly 85 GW, and even after accounting for historical withdrawal rates, the remaining viable projects would require a doubling of generation and transmission infrastructure within a decade. Because Texas operates largely outside federal jurisdiction, the burden of planning and cost allocation falls almost entirely on state policymakers and ERCOT stakeholders.
The Batch Zero process was designed to bring order to the chaos by clustering projects into study groups and assigning network upgrade costs more transparently. Halting it now injects uncertainty for developers, utilities, and investors who had begun pricing projects around the new timeline. Meanwhile, other states — particularly in PJM and MISO territories — are watching closely as they confront their own data-center-driven queue backlogs, and the Texas episode may accelerate calls for federal queue reform or minimum interconnection standards.
For Texas ratepayers, the stakes are concrete: every gigawatt of new load that connects without adequate firm generation or transmission reinforcement raises the risk of scarcity pricing events like those seen during Winter Storm Uri. The audit ordered by Abbott could lead to stricter entry requirements, such as mandatory on-site generation or firm capacity commitments, reshaping the economics of data center siting in the state. How ERCOT balances the revenue lure of hyperscale loads against its reliability mandate will set a precedent for every grid operator facing the AI-driven demand surge.
