At last week’s Regulatory Information Conference, Jamie Pelton cochaired a panel on Palisades nuclear power plant’s restart—a “historic restart,” as she put it.

Her choice of words was perhaps an understatement. After all, no U.S. nuclear plant has yet restarted after being slated for decommissioning.

Nuclear powerhouse Constellation announced today the signing of a 20-year power purchase agreement with Microsoft that will pave the way for the restart of Three Mile Island Unit 1—under a new name to honor Chris Crane, former chief executive of Exelon when Constellation was part of the larger company.
