ERCOT Pauses Data Center Interconnection as 474 GW Queue Piles Up

Texas Governor Greg Abbott ordered an audit on August 3 of data centers in the interconnection queue of the Electric Reliability Council of Texas (ERCOT), the state's grid operator, amid 474 GW in requests, more than five times its record peak demand. ERCOT responded by pausing the "Batch Zero" study, the first batch under its new interconnection process for large loads, according to Latitude Media.

Abbott called for any project that fails the audit to be rejected. The review will examine whether data centers are self-sufficient or depend on the grid, their water consumption and sources, and whether they receive state or local financial assistance. According to Utility Dive, the governor warned that the scale of development threatens grid reliability, with requests for new capacity totaling 474 GW, 90% of them from data centers. ERCOT had previously warned that its May forecast, projecting a quadrupling of demand by 2032, rested partly on speculative requests.

The pause is not a moratorium on construction, but on grid connection, notes Latitude Media's analysis. The industry read is that the measure will push developers toward private off-grid schemes: campuses with their own gas turbines, faster to build but without backup in the event of a failure and with no clear path to cleaner supply. The Data Center Coalition called on regulators to quickly distinguish speculative projects from committed ones. In the corridor between the U.S. Gulf and Latin America, ERCOT is the electrical node on the U.S. side of the bridge, and this slowdown modulates the pace of AI demand competing for capital and turbines with projects in Mexico and the region.

ERCOT plans to request on August 20 a good-cause exemption from the Public Utility Commission of Texas (PUCT) to resume the study. The outcome will determine whether the queue is cleared or the pause extended, and how much isolated generation is installed in the interim. That figure will be the signal for the rest of the corridor.
