Texas has imposed a moratorium on new data center connections that threatens roughly 20% of the entire U.S. development pipeline, and BloombergNEF analysts warn the longer the pause persists the harder it will be to restart because interconnection queues continue advancing while projects sit idle.
The Electric Reliability Council of Texas (ERCOT) moved to slow approvals after a surge of large-load interconnection requests — many tied to artificial intelligence and cryptocurrency operations — raised concerns about grid stability and cost allocation. Texas has attracted an outsized share of national data center investment thanks to its deregulated market, abundant wind and solar generation, and historically low industrial power prices. That same openness now creates a bottleneck: the grid operator cannot easily distinguish speculative requests from financed projects, and the sheer volume risks overwhelming transmission planning processes.
Interconnection queues operate on a first-come, first-served basis across most U.S. markets. When a moratorium freezes new applications, projects already in the queue keep moving through studies and upgrades, but new entrants lose their place in line. For developers, that can mean years of additional waiting once the pause lifts, because they must re-enter a queue that has grown longer in the meantime. BNEF notes that Texas currently holds more than 30 gigawatts of data center capacity in various stages of interconnection review — a figure that dwarfs the near-term buildout in any other state.
The stakes extend beyond Texas. Data centers are now the single largest driver of U.S. electricity demand growth, with national load forecasts revised upward by 20 to 40 gigawatts over the next five years. Delays in the Texas pipeline ripple into national supply chains for servers, cooling equipment, and long-lead-time electrical gear. They also complicate resource adequacy planning for utilities and grid operators nationwide, who must account for the timing and location of new large loads when scheduling generation retirements and transmission upgrades.
Regulators face a delicate balance: ensuring that the grid can absorb rapid, concentrated demand without shifting costs to residential ratepayers, while avoiding a de facto moratorium that chills investment in digital infrastructure the broader economy depends on. ERCOT has signaled it will refine its screening process rather than maintain a blanket pause, but the episode underscores a structural mismatch — interconnection processes designed for incremental generation additions are ill-suited to the speed and scale of hyperscale computing demand.
