The context: The plant, now known as Crane Clean Energy Center, is set to power Microsoft data centers. This would become the country’s first fully revived nuclear power plant.
But first, PJM needs to get some transmission upgrades out of the way, Constellation announced at CERAWeek. This will push the project’s interconnection timeline back to 2031—four years behind schedule. Now, Constellation is negotiating with transmission owners to speed things up.
By the way: Constellation also wants to run the country’s oldest operating nuclear plant—the nearly 60-year-old, 630-MW Nine Mile Point Unit 1—for two more decades. Amid looming power shortfalls, New York’s four nuclear reactors are seen as key to ensuring grid reliability.
