Constellation Energy
firmAI & Compute
A tech giant is restarting a shut-down nuclear plant just to feed its AI computers.
Who they are
The largest nuclear power operator in the United States.
What they do
The engine flags it as a pressure point where energy supply and the AI boom collide.
How it works
In September 2024 it signed a 20-year deal with Microsoft to restart Three Mile Island Unit 1 (renamed Crane Clean Energy Center), and a June 2026 federal waiver locked that steady power supply to serve massive AI data centers.
Why it matters
It shows that AI's growth now depends on grabbing dedicated power sources, making electricity itself a chokepoint in the tech race.
