The US Department of Energy’s Loan Programs Office (LPO) closed a $1 billion loan to restart Three Mile Island Unit 1, a nuclear reactor at Three Mile Island in Londonderry Township, Pennsylvania.
The money is being loaned to Constellation Energy Generation, which is renaming the 835 megawatt (MW) Three Mile Island Unit 1 the Crane Clean Energy Center. Constellation said in September 2024 that it would restart the reactor under a power purchase agreement with Microsoft, which needs more clean power to feed its growing data-center demand.
The project is estimated to cost around $1.6 billion, and the DOE says the project will create around 600 jobs. The reactor is expected to start generating power again in 2027.
Three Mile Island Unit 1 (in the foreground in the photo above) went offline in 2019 because it could no longer compete with cheaper natural gas, but it wasn’t decommissioned. It’s capable of powering the equivalent of approximately 800,000 homes. It’s on the same site as the Unit 2 reactor (in the background in the photo above) that went into partial nuclear meltdown in 1979, and is known as the worst commercial nuclear accident in US history.
When asked about the loan’s timing, Greg Beard, senior adviser to the Loan Programs Office, told reporters on a call that it would “lower the cost of capital and make power cheaper for those PJM [Pennsylvania-New Jersey-Maryland] ratepayers.” Data centers are driving up electricity costs for consumers.
