The limit isn’t money anymore. It’s electricity. The data center construction boom that’s filling contractor backlogs is running headlong into a power grid that can’t grow fast enough to feed it.
The numbers are stark. More than 700 data centers are under construction across 38 states, and announced projects now total roughly 780 gigawatts of demand. For scale, the entire U.S. peak load is about 759 gigawatts. The pipeline of announced computing load is bigger than everything the country draws at once today.
The data center construction math doesn’t add up
Most of that 780 gigawatts will never get built, and everyone in the room knows it. Developers announce sites to lock up land and power options, then quietly let the weakest ones lapse. The hard constraint is the interconnection queue: the years-long wait to tie a new load into the grid. PJM, the largest U.S. grid operator, already projects it will fall six gigawatts short of its reliability targets in 2027.
That gap is showing up on power bills. Utilities asked regulators for $9.4 billion in rate increases in just the first quarter of 2026, and households near big data center clusters have seen the steepest jumps.
Interconnection is the new critical path
For builders, the choke point has moved. A few years ago the question was financing. Now it’s whether a project can actually get power, and when. That’s pushing developers toward sites with existing substations, behind-the-meter generation, and even on-site gas, and it’s turning utility coordination into a make-or-break part of the schedule.
The projects that pencil out are the ones with power already lined up, like Meta’s Hyperion campus and its Lebanon, Indiana build. The ones that don’t will stay press releases. Expect the announced-versus-built gap to widen, and expect “do you have power?” to become the first question on every data center bid.
