What it is
Constellation is the largest US operator of nuclear plants and became the face of the AI-nuclear boom by signing a 20-year PPA with Microsoft to restart Three Mile Island Unit 1 (rebranded the Crane Clean Energy Center), targeting ~2027-2028. It is also acquiring Calpine to expand its generation fleet. Constellation's existing ~22 GW nuclear fleet makes it the go-to counterparty for hyperscalers seeking firm carbon-free power without waiting for new-build reactors.
