Alcoa to Sell Idled Aluminum Smelter to NYDIG for Bitcoin Mining Infrastructure

According to Cointelegraph, Alcoa Inc. is set to strike a deal with Bitcoin mining firm NYDIG to sell its idle Massena East aluminum smelter in New York State, with the transaction expected to close by mid-year. The facility has been offline since 2014 and features an on-site substation, transmission lines, and high-capacity grid connectivity—plus access to hydropower supplied by the New York Power Authority—making it attractive to Bitcoin miners and data center operators. The report notes that some decommissioned industrial sites across the U.S. are being repurposed as Bitcoin mining, artificial intelligence, and high-performance computing facilities.
