Microsoft-Constellation Three Mile Island restart (2024)
Microsoft signed a 20-year power purchase agreement with Constellation to restart Three Mile Island Unit 1 in Pennsylvania, renamed the Crane Clean Energy Center. The restart is expected online in 2028.
The deal established the hyperscaler-as-anchor-customer model for nuclear power.
It showed tech companies would pay a premium for firm, carbon-free power, opening the door for similar deals.
This Google deal extends the same model from restarting a shuttered plant to uprating operating reactors.
