Alcoa Sells 1,300-Acre Massena East Smelter to NYDIG for Bitcoin Mining Hub

Alcoa has confirmed the sale of its idle 1,300-acre Massena East smelter in New York to NYDIG, transforming the 435MW hydropower site—already hosting 54,000 Bitcoin miners at 166MW—into a major mining facility, with closure targeted for mid-2026 pending approvals. Reports began April 18 with advanced talks on the deal, progressed through April 19-20 with details on NYDIG's operations via Coinmint and its prior 270MW Crusoe acquisition, and culminated April 21 in the sale announcement amid Alcoa's pitch of 10 U.S. sites to crypto firms. The transaction bolsters U.S. mining infrastructure near $75,000/BTC, supporting miner economics and Bitcoin's ecosystem.
