LONDONDERRY TOWNSHIP, Pa. (WHTM) — The Constellation Energy Corporation announced its plan to restart the Unit 1 nuclear reactor at Three Mile Island as part of a purchase agreement with Microsoft.
Five years ago today, TMI shut down Unit 1, located near Harrisburg on the Susquehanna River, for economic reasons. The Unit 1 reactor is located adjacent to TMI Unit 2, which shut down in 1979 after a historic partial meltdown caused by a combination of human and mechanical errors.

Constellation said this 20-year power purchase agreement will not only restart the unit 1 nuclear reactor but will also pave the way for the launch of the Crane Clean Energy Center (CCEC).
Microsoft has agreed to purchase energy from the plant to match the power its data centers use with carbon-free energy.

“Powering industries critical to our nation’s global economic and technological competitiveness, including data centers, requires an abundance of energy that is carbon-free and reliable every hour of every day, and nuclear plants are the only energy sources that can consistently deliver on that promise,” said Joe Dominguez, president and CEO, Constellation.
“Before it was prematurely shuttered due to poor economics, this plant was among the safest and most reliable nuclear plants on the grid, and we look forward to bringing it back with a new name and a renewed mission to serve as an economic engine for Pennsylvania. We are especially honored to name this new plant after our former CEO Chris Crane, who was a fierce advocate for our business, devoting his entire career to the safe, reliable operation of our nation’s nuclear fleet, and we will continue that legacy at the Crane Clean Energy Center,” he added.

Multiple steps must be taken to restart a nuclear reactor in the U.S., and this starts with a significant investment to properly restore the plant. Constellation said that restarting a nuclear power plant requires U.S. Nuclear Regulatory Commission approval, a detailed safety and environmental review, and permits from state and local agencies.
Additionally, Constellation said it will pursue a separate license renewal that will extend the plant’s operations to 2054 as soon as possible.
They said that they plan to have the CCEC online in 2028.
