[FLASH] Constellation signs 20-year Amazon PPA at Calvert Cliffs; uprates add ~190 MW, shares fall 4% on the day
Constellation and Amazon announced a 20-year power purchase agreement tied to the Calvert Cliffs nuclear plant in Maryland, with Constellation to fund uprates adding about 190 MW of capacity and local coverage citing roughly 690 MW under contract and an investment of around $3 billion (Constellation release; Baltimore Sun; Maryland Matters; WTOP). It is the latest dated hyperscaler-nuclear offtake after the Meta-Vistra and Microsoft-Crane deals and extends the 'AI data centers as grid event' theme. CEG nonetheless closed down about 4% at $254.02 before rebounding after hours, so the market's pricing of the contract is unresolved; watch the Oct 1 session and any FERC or Maryland PSC filing.
