Microsoft has entered into a 20-year agreement with Constellation Energy to revive the Three Mile Island nuclear plant in Pennsylvania. This $1.6 billion investment aims to restart the dormant reactor, which has been offline since 2019, and provide carbon-free electricity for Microsoft’s expanding data centres.
Reviving a Historic Site
The Three Mile Island plant is infamous for the 1979 accident that resulted in a partial meltdown at one of its reactors, marking it as the worst nuclear incident in U.S. history. While one reactor was permanently shut down following the accident, the second reactor was closed in 2019 due to economic challenges. Constellation plans to invest heavily in refurbishing this reactor, with hopes of bringing it back online by 2028, pending regulatory approvals.
Meeting Growing Energy Needs
Microsoft’s commitment to purchasing all the electricity generated by the reactor underscores the tech giant’s urgent need for reliable power sources to support its data centres, which are increasingly reliant on AI technologies. The deal marks a pivotal moment for both Microsoft and the nuclear industry, as it represents the first dedicated supply from a fully nuclear facility for the company.
As demand for electricity surges due to technological advancements and increased reliance on cloud computing, there is renewed interest in nuclear power as a stable source of energy. Constellation’s CEO, Joe Dominguez, emphasised that nuclear energy is crucial for meeting continuous power needs without carbon emissions.
Economic Impact and Job Creation
The revival of the Three Mile Island plant is expected to create approximately 3,400 jobs and generate over $3 billion in state and federal taxes. Constellation plans to fund the project independently without relying on state or federal aid, although it will benefit from federal tax credits under the Inflation Reduction Act for the energy produced.
The project aligns with Microsoft’s broader sustainability goals, aiming to operate all its data centres on clean energy by 2025 and achieve carbon negativity by 2030. Bobby Hollis, Microsoft’s vice president for energy, stated that this partnership is a significant step towards decarbonising the grid and ensuring reliable energy supply.
Conclusion
The partnership between Microsoft and Constellation Energy to restart the Three Mile Island nuclear plant highlights a strategic shift towards utilising nuclear power amidst rising energy demands from AI and data centres. As both companies work towards sustainable energy solutions, this initiative could serve as a model for future collaborations in addressing global energy challenges while promoting environmental responsibility.
