Nuclear Plant Restart Hinges on Grid Access
6 Apr
Summary
- Restart of Three Mile Island nuclear plant faces delays.
- Power line projects are causing the critical postponements.
- Plant owner seeks waivers for speedy grid connection.

Multiple delayed power line projects are threatening the planned restart of the Three Mile Island nuclear power plant in Pennsylvania. Owner Constellation Energy has indicated these infrastructure issues could postpone the facility's return to operation.
The company is working to bring a reactor at the site, renamed the Crane Clean Energy Center, back online by the end of 2027. This restart is tied to a contract to supply electricity for Microsoft's data centers.
Constellation Energy has filed with federal energy regulators, requesting waivers to speed up the nuclear facility's grid connection. The urgency stems from the critical need to resolve power line access for the planned operational start date.
