Texas Data Center Pause Puts 49.8 GW in Limbo as BNEF Flags 20% of U.S. Pipeline at Risk
Bloomberg NEF warns Abbott's interconnection freeze threatens $8 billion in potential data center revenue losses across a stalled 49.8 GW project queue.
Bloomberg NEF said on Wednesday (2026-08-05) that Texas Governor Greg Abbott's pause on data center grid interconnections puts approximately 49.8 GW of projects on hold and threatens around 20% of the total U.S. data center pipeline with delay — the firm's sharpest quantification yet of how a single state-level decision has rippled across the national buildout.7
Abbott ordered the halt on Monday (2026-08-03), triggering an audit of all data centers in ERCOT's interconnection queue. That queue had already swelled to roughly 474 GW of pending requests, a backlog that dwarfs the grid's existing installed capacity. ERCOT subsequently delayed its review of the first batch of projects attempting to navigate the state's new large-load interconnection process.6,7
The revenue exposure BNEF attached to the freeze is stark. The firm estimates AI computing capacity can earn around $1.76 billion per gigawatt per month, and puts potential data center revenue losses at $8 billion by the end of the delay period. BNEF had been forecasting roughly 1.2 GW of total ERCOT data center additions between the second quarter of 2026 and the first quarter of 2027, and around 8.25 GW of additional capacity through 2030, which would have brought cumulative ERCOT data center load above 17 GW. Both figures now carry material delay risk.7
Abbott's order landed on top of a process that was already moving slowly. ERCOT's board had approved two sets of landmark rules on Tuesday (2026-06-02) to govern how large electricity users connect to the grid, reviewing them in batches rather than individually, and introducing curtailment obligations under Texas Senate Bill 6 for loads above 75 MW connecting after the end of 2025. Those rules were designed to impose order. The audit added a harder stop before they could take effect.3,4
The queue numbers themselves had already forced a reality check from ERCOT's own leadership. Chief executive Pablo Vegas said on Tuesday (2026-06-02) that the grid operator's earlier projection — that as much as 228 GW of queued capacity could come online by 2032 — was "too high of a figure based on realistic expectations." Jeff Billo, ERCOT's vice president of interconnection and grid analysis, said at the same session that he expected roughly 100 GW worth of projects to meet criteria for Batch Zero, the first cohort under the new rules.3
Even setting the queue aside, the demand trajectory was already testing ERCOT's operational limits. Dan Woodfin, ERCOT's vice president of system operations, warned that demand could rise above 92 GW during periods of hotter-than-normal weather, driven by crypto-mining and data center load growth. The grid's previous peak was 85.5 GW, set in August 2023. Some individual data center campuses under development, according to E&E News, could consume more than 4,000 MW — enough to power roughly one million homes.3,2
The curtailment rules that accompanied the batch-review framework had already drawn resistance from industry. The Texas Blockchain Council and the Texas Industrial Energy Consumers warned that compliance could cost billions and take years of facility redesign, making grid connection potentially unworkable for some operators. Abbott's freeze arrived before that argument had been resolved.2
Texas is not operating in isolation. New York Governor Kathy Hochul signed an executive order imposing a statewide moratorium on new large-scale data centers — the first such state-level freeze in the country — blocking permitting for facilities requiring power above a certain threshold for up to one year.5 The North American Electric Reliability Corporation issued its highest-level warning, a Level 3 alert, during the week of 2026-05-04, citing specific incidents it observed in 2024 as evidence of systemic risks from rapid data center growth.1
The immediate sequence that determines the outcome for the 49.8 GW of paused projects is straightforward to describe and hard to time: Abbott's audit must conclude, ERCOT must restart its Batch Zero review, and developers must decide whether the curtailment framework under Senate Bill 6 is workable enough to justify re-entering the queue. Until that sequence runs its course, the revenue clock BNEF identified at $1.76 billion per gigawatt per month keeps accumulating against projects that have not yet been energized.7
