About 35% of Planned U.S. Data-Center Capacity May Be Built

Only about 35% of announced U.S. data-center capacity is likely to be built, suggesting the pipeline includes far more proposed capacity than projects likely to materialize.

The estimate draws on thousands of planned facilities. It comes as electricity shortages delay projects and developers face practical hurdles to turning announcements into construction, including securing power, permits and customers.

Some of the largest proposals have been called “bragawatts.” The term describes big projects announced by companies that often have little experience building data centers. Some proposals have not secured electricity, construction permits or customers.

A separate source of inflated project counts comes from developers seeking power connections at several locations at once. They submit requests while searching for a site that can work, hoping one of the locations will prove viable. In Texas, those requests amount to more than five times the state’s existing electricity supply.

The requests include competing site options, so the volume does not represent an equivalent amount of confirmed construction. It can make the grid pipeline appear larger than the set of projects likely to move ahead.

The gap between proposed capacity and likely construction does not mean the data-center expansion is fictitious. Electricity shortages are delaying real projects, and the buildout still faces power-market constraints. The estimate instead points to a mix of genuine infrastructure challenges and speculative plans in the announced project pipeline.
