U.S. Secretary of Energy Chris Wright announced on November 18 that the Department of Energy’s Loan Programs Office has finalized a $1 billion loan to help lower energy costs and restart a Pennsylvania nuclear power plant. The funding will support Constellation Energy Generation, LLC in financing the Crane Clean Energy Center, an 835 MW facility located on the Susquehanna River in Londonderry Township, Pennsylvania. This loan marks a major step toward restoring reliable, carbon-free power to the region.
Energy Secretary Wright highlighted further,
“Thanks to President Trump’s bold leadership and the Working Families Tax Cut, the United States is taking unprecedented steps to lower energy costs and bring about the next American nuclear renaissance. Constellation’s restart of a nuclear power plant in Pennsylvania will provide affordable, reliable, and secure energy to Americans across the Mid-Atlantic region. It will also help ensure America has the energy it needs to grow its domestic manufacturing base and win the AI race.”
Constellation (Nasdaq: CEG) is the first company to receive a simultaneous conditional loan commitment and financial close from the DOE Loan Programs Office. Its strong finances and credit rating allowed the process to move quickly. The loan, provided through the Energy Dominance Financing Program, will lower financing costs and attract private investment to restart the plant. In addition, DOE noted the project will help the U.S. stay competitive in the global AI and digital economy, which is driving higher electricity demand.
Crane Clean Energy Center: Returning 835 MW of Carbon-Free Power
The Crane Clean Energy Center is an 835-megawatt nuclear plant on the Susquehanna River. Previously known as Three Mile Island Unit 1, it has a long and historic legacy. In March 1979, Three Mile Island Unit 2 suffered a partial meltdown and has remained in monitored storage ever since. Unit 1, however, continued operating safely for four decades before being shut down in September 2019 due to market conditions rather than safety concerns.
In September 2024, Constellation signed a 20-year power purchase agreement with Microsoft, which allows the tech giant to buy the carbon-free electricity generated by the restarted plant. Following the agreement, Constellation rebranded the facility as the Crane Clean Energy Center. As said before, once operational, the plant will provide 835 MW of nuclear energy.
DOE Loan Accelerates the Restart
Constellation (Nasdaq: CEG) is the first company to receive a simultaneous conditional loan commitment and financial close from the DOE Loan Programs Office. Its strong finances and credit rating allowed the process to move quickly. The loan, provided through the Energy Dominance Financing Program, will lower financing costs and attract private investment to restart the plant. In addition, DOE noted the project will help the U.S. stay competitive in the global AI and digital economy, which is driving higher electricity demand.
DOE stated that the Crane loan aligns with President Trump’s Executive Order on Reinvigorating the Nuclear Industrial Base. The project is the first under this administration to receive a simultaneous conditional commitment and financial close.
Because the reactor was never fully decommissioned, restarting it is faster and more cost-effective than building a new plant. The loan will fund equipment inspections, system upgrades, workforce training, and regulatory compliance. Once approved by the Nuclear Regulatory Commission, the plant will supply enough electricity to power about 800,000 homes across the PJM Interconnection region. It will help lower electricity costs, strengthen grid reliability, and create hundreds of jobs.

Pennsylvania Leads in Clean Energy and AI Power
Senator Dave McCormick praised the DOE loan, saying Pennsylvania is leading the nation in energy independence and AI innovation. He highlighted that the restart will deliver more than 800 MW of carbon-free electricity and create 3,400 direct and indirect jobs.
McCormick also noted Constellation’s ongoing investments across the state, including commitments announced at the Pennsylvania Energy and Innovation Summit. The restart comes amid unprecedented electricity demand from AI, cloud computing, and expanding data centers.
A Goldman Sachs report predicts that AI could increase data-center power demand by 160 percent. AI queries, like those used by tools such as ChatGPT, require nearly ten times more electricity than a standard Google search. Nuclear power is vital to meet this growing demand reliably.
Extending Nuclear Plant Life: Constellation’s Strategy for Reliable Power
Constellation has invested in local communities by committing over $1 million in charitable contributions over five years. In 2025 alone, the company donated $200,000 to support nonprofits, workforce programs, and local initiatives.
Significantly, restarting Crane is part of Constellation’s larger multi-billion-dollar plan to extend the life of America’s nuclear fleet, increase output, and ensure reliable power for decades.
The Crane Clean Energy Center is expected to deliver significant economic benefits to Pennsylvania. An analysis by the Pennsylvania Building and Construction Trades Council projected that the restart would create thousands of direct and indirect jobs. It could add more than $16 billion to the state’s GDP and generate over $3 billion in state and federal tax revenue.
The plant is already more than 80 percent staffed, with over 500 employees, including engineers, mechanics, technicians, and licensed operators. Regulatory reviews and technical inspections remain on schedule.
Joe Dominguez, president and CEO of Constellation, said:
“DOE’s quick action and leadership is another huge step towards bringing hundreds of megawatts of reliable nuclear power onto the grid at this critical moment. Under the Trump administration, the FERC and DOE have made it possible for us to vastly expedite this restart without compromising quality or safety. It’s a great example of how America first energy policies create jobs, growth and opportunities and make the grid more reliable. Utilities and grid operators are moving too slowly and need to make regulatory changes that will allow our nation to unlock its abundant energy potential. Constellation and nuclear energy are helping to lead the way and we are thankful to President Trump and Secretary Wright for putting the ‘energy’ back into DOE.”
Nuclear Power for America’s Clean Energy Future
The surge in AI, electrification, and cloud computing has made nuclear energy more critical than ever. Small modular reactors and advanced technologies are gaining interest from utilities and data-center developers.
The U.S. produces about 30 percent of the world’s nuclear electricity. Ninety-four reactors supply steady, clean power to millions of homes and industries nationwide. According to the World Nuclear Association, U.S. reactors generated 779 terawatt-hours in 2023, accounting for 19 percent of the nation’s total electricity output.
The administration aims to quadruple U.S. nuclear capacity to 400 gigawatts by 2050. The International Energy Agency projects 35 GW of new capacity by 2035 and 200 GW by 2050, nearly triple current levels. Restarting Crane contributes to this goal while providing reliable baseload power, supporting AI and digital growth, and boosting the economy.
