Available to All Users
On September 20, 2019, the Three Mile Island Unit 1 generating station shutdown for economic reasons, despite being one of the best performing plants on the grid. Exactly five years later, Constellation Energy Generation (CEG) announced the unit would re-start as the Crane Clean Energy Center (CCEC), including a 20-year power purchase agreement with Microsoft to power Microsoft’s growing artificial intelligence (AI) and data center portfolio.
During an ANS Chicago-Great Lakes Local Section hybrid event, Trevor Orth, Plant Manager of Crane Clean Energy Center, and Darani Reddick, Director, Nuclear Regulatory Strategy & Policy, Constellation Energy Generation, LLC, discussed the technical aspects of the restart including the material condition and improvements, and touch on the still-evolving relicensing and regulatory environment.
