After closing five years ago due to financial troubles, the nuclear reactor at the Three Mile Island plant in central Pennsylvania could restart under a new Microsoft deal, writes Andrew Seidman for The Philadelphia Inquirer.

The owner of the plant, Baltimore-based Constellation Energy, has signed a 20-year agreement with Microsoft under which the software giant will buy power from Three Mile Island Unit 1. The reactor is located in a separate facility from Unit 2, which was taken out of commission in 1979 after experiencing a partial meltdown.

Constellation will spend $1.6 billion to bring Unit 1 back online and it does not plan to ask for grants from either the state or federal governments. Restart needs to be approved by federal regulators, though Gov. Josh Shapiro has already indicated his support for the project.

The reactor is expected to be back online by 2028.

“I think policymakers have recognized that a strategy that is dependent just on wind, solar, batteries isn’t going to fully get us there and meet the needs of the system from a reliability standpoint,” said Joe Dominguez, Constellation’s president and CEO.
