The Trump administration has moved forward with a major decision in the U S energy sector by approving a 1 billion dollar federal loan to restart the Three Mile Island nuclear reactor in Pennsylvania. Once synonymous with one of the most discussed incidents in nuclear history, the site is now being positioned as a key contributor to the future of clean and reliable energy. The loan, announced by the Department of Energy, is directed to Constellation Energy Generation and is intended to finance the restart and modernization of the 835 megawatt unit, which previously ceased operations in 2019 but was never fully decommissioned.
This initiative aligns with the administration’s stated goals of strengthening American energy independence, supporting low carbon power sources and boosting industrial growth across the country. The restarted facility, now rebranded as the Crane Clean Energy Center, is expected to provide power to hundreds of thousands of homes across the mid Atlantic region while also supporting advanced technologies and manufacturing.
Background Of The Three Mile Island Reactor
Three Mile Island is one of the most well known nuclear power sites in the United States. Located in Londonderry Township, Pennsylvania, it previously operated multiple units and became part of the national conversation on nuclear safety and regulation. Unit 1, the reactor at the center of the current decision, was shut down in 2019 due to economic pressures and market conditions, despite still being technically capable of operation.
Rather than being fully decommissioned, Unit 1 remained in a state where future reactivation was still possible. This created the opportunity for Constellation Energy Generation and the federal government to reevaluate the strategic value of the plant in the context of energy policy, climate goals and technological needs.
The 1 billion dollar federal loan represents a turning point in how legacy nuclear assets are viewed. Instead of allowing these large assets to remain idle or reach full decommissioning, the new approach focuses on using them to add reliable, carbon free power back to the grid at a time when electricity demand is expected to climb.

Details Of The 1 Billion Dollar Federal Loan
The loan was formally announced by the U S Department of Energy as part of its commitment to expanding nuclear power capacity and supporting large scale clean energy projects. The funds will be used by Constellation Energy Generation to finance key aspects of the restart, including safety upgrades, refurbishment of critical systems, regulatory compliance, infrastructure improvements and workforce expansion.
According to Constellation, the structure of the federal loan will help lower the overall cost of capital for the project. By reducing financing costs and leveraging private investment, the loan is intended to make the restart of the Three Mile Island reactor commercially viable while protecting taxpayers through established federal loan guarantee frameworks.
The plant, once fully operational, is projected to generate electricity equivalent to the needs of approximately 800,000 homes in the PJM Interconnection region, which spans 13 states in the eastern United States. This level of capacity is significant in an era of rising demand from data centers, electrification of transport and growth in advanced manufacturing.
Alignment With Trump Administration Energy Policy
The decision to provide a 1 billion dollar loan to restart Three Mile Island is consistent with the Trump administration’s broader strategy of reinforcing American energy independence and reliability. The administration has repeatedly emphasized the importance of all forms of domestic energy production, including nuclear, as a way to reduce reliance on foreign sources and stabilize long term energy prices.
Earlier executive actions from the administration have focused on accelerating the development and permitting of energy projects, including nuclear power plants and advanced reactors. Nuclear energy is seen as a critical component of a balanced energy mix because it provides large scale, low carbon baseload power that can operate continuously, regardless of weather conditions.
Energy Secretary Chris Wright highlighted that the restart of the nuclear power plant is not only about increasing electricity supply but also about supporting the growth of domestic manufacturing and maintaining a competitive edge in emerging technologies such as artificial intelligence. Reliable and affordable power is considered essential for data centers, high performance computing facilities and other energy intensive infrastructure needed to support modern industries.
Role Of Constellation Energy Generation And Microsoft
Constellation Energy Generation is at the center of the project as the owner and operator of the facility. The company has rebranded the site as the Crane Clean Energy Center to reflect its future role as a source of clean, reliable power. Constellation’s leadership has described the Department of Energy’s loan as a major step toward bringing hundreds of megawatts of nuclear generation back to the grid at a crucial time.
An important pillar supporting the restart is a 20 year power purchase agreement that Constellation signed with Microsoft. This long term contract provides a stable revenue foundation for the project by committing a major technology company to purchase a substantial portion of the plant’s output. For Microsoft, the agreement helps secure low carbon electricity for its data centers and operations, aligning with its climate and sustainability targets.
The collaboration between a nuclear operator, the federal government and a leading technology firm illustrates how energy projects are increasingly tied to digital infrastructure and the demand for clean power from large corporate customers.
Economic And Employment Impact
The restart of Three Mile Island’s Unit 1 is expected to have meaningful economic benefits for Pennsylvania and the broader region. According to Constellation, the Crane Clean Energy Center is already around 80 percent staffed, with more than 500 employees working on site. As the project advances, it will support additional jobs in construction, engineering, safety oversight, logistics and local services.
Beyond direct employment, the plant’s operation will contribute to the local tax base and support community development initiatives. The presence of a large, stable industrial employer can also encourage related investments in the surrounding area, including manufacturing, infrastructure and technology facilities that depend on reliable power.
On the national level, adding hundreds of megawatts of nuclear capacity helps stabilize grid operations, reduce reliance on imported fuels and support the objectives of energy security and affordability. This can indirectly benefit households and businesses across the mid Atlantic region by contributing to a more resilient and diversified power mix.
Safety, Regulation And Public Confidence
Any decision involving nuclear power brings questions about safety, regulation and public confidence. The restart of the Three Mile Island reactor will proceed under the close supervision of federal regulators, including the Nuclear Regulatory Commission. Before the plant can return to commercial operation, it must meet stringent safety requirements that cover reactor systems, emergency preparedness, radiation protection and environmental safeguards.
The process will involve detailed inspections, testing and verification of modernized equipment and safety protocols. Communication with local communities, state authorities and emergency management agencies is also a critical part of building trust and ensuring that all stakeholders understand the plant’s operations and contingency plans.
Supporters of the project argue that modern nuclear plants benefit from decades of improved technology, more robust regulatory frameworks and extensive operational experience. They see the restart as an opportunity to demonstrate how existing nuclear infrastructure can be safely integrated into a clean energy future.
Future Outlook For Nuclear Energy In The United States
The Three Mile Island decision could signal a broader trend in the U S nuclear sector. Instead of allowing older plants to close permanently, federal support and private partnerships may lead to more restarts, life extensions and modernization projects. At the same time, the industry is exploring advanced reactor designs and small modular reactors, which aim to provide flexible, lower cost nuclear options.
If the Crane Clean Energy Center restart proceeds successfully, it may serve as a model for how financial tools, corporate power purchase agreements and federal policy can work together to unlock low carbon energy capacity. For the Trump administration, the project supports its message that the country can grow its economy, expand manufacturing and remain competitive in critical technologies while still investing in cleaner energy sources.
