Constellation to Launch Crane Clean Energy Center, Restoring Jobs and Carbon-Free Power to the Grid

Constellation signs its largest-ever power purchase agreement, with Microsoft, a deal that will restore Three Mile Island (TMI) Unit 1 to service and keep it online for decades; named for Chris Crane, CEO of Constellation’s former parent company and a true titan of the nuclear industry.

What a Restart Means for the Community

 

This new center, expected to go online in 2028, will: 

  • Restore 835 megawatts of reliable, clean, carbon-free energy to the grid
  • Create 3,400 direct and indirect jobs
  • Deliver $3.6 billion in state and federal tax revenue and add $16 billion to the state’s GDP
  • Reduce 61 million tons of CO2 emissions over 20 years
  • Read more about CCEC’s environmental and economic impacts here.

 


Community outreach, engagement and dialogue are cornerstones of our restart plan. 

To ensure that the local community fully participates in the economic benefits of restarting the facility, Constellation has committed an additional $1 million in philanthropic giving to the region over the next five years to support workforce development and other community needs.

This site was designed to engage and inform the local community. It will be updated as new information and resources are available. Be sure to check this page for updates and information about community events.

 
  • Restarting a nuclear reactor requires Nuclear Regulatory Commission approval following a comprehensive safety and environmental review, as well as permits from state and local agencies.
  • Constellation will pursue a license to extend operations to at least 2054 and expects the plant to be ready for service by 2028, after making a significant investment to fully restore the facility’s robust safety and operations systems.
  • There will be opportunities for the public to learn more about this application as part of the NRC’s review process.

 

 
  • Safety is Constellation’s first and most critical obligation. Nuclear power plants are among the best-protected private sector facilities in America, with monitoring and inspections by plant owners, local officials, and the federal government.
  • The Unit 1 reactor is located adjacent to TMI Unit 2, which shut down in 1979 and is in the process of being decommissioned by its owner, Energy Solutions. TMI Unit 1 is a fully independent facility, and its long-term operation was not impacted by the Unit 2 accident.  TMI Unit 1 was retired for economic reasons in 2019.
