Aluminum Giant Alcoa To Sell Dormant Smelter To Bitcoin-Miner NYDIG: Report

US aluminium giant Alcoa is reportedly nearing a deal to offload its long-idle Massena East smelter in upstate New York to Bitcoin mining firm New York Digital Investment Group (NYDIG).

The company is in advanced discussions and expects the transaction to close “in the middle part of this year,” CEO Bill Oplinger told Bloomberg on Friday. The site, located along the St. Lawrence River, has been inactive since 2014 after Alcoa shut it down amid rising energy costs and global competition.

Built for 24/7 heavy industrial operations, aluminum smelters come with pre-existing substations, transmission lines and high-capacity grid connections. That makes them attractive targets for Bitcoin miners and data center operators, who often spend years securing similar infrastructure approvals from scratch.

Massena East also benefits from hydropower supplied by the New York Power Authority, a key draw for energy-intensive computing firms seeking low-cost and lower-carbon power sources.

US smelters reborn as crypto, AI data centers

The potential sale comes amid a broader trend across the US, where retired industrial sites are being repurposed for digital infrastructure. Earlier this year, Century Aluminum sold its Hawesville smelter in Kentucky to TeraWulf for $200 million, with plans to convert it into a high-performance computing and AI facility rather than traditional industrial use.

Meanwhile, NYDIG has been growing its footprint in Bitcoin mining infrastructure. The firm, owned by Stone Ridge, already holds a stake in Coinmint, which operates mining hardware at the same campus under a long-term lease.

Last year, Crusoe Energy also agreed to sell its Bitcoin mining business, including its digital flare mitigation operations, to NYDIG.

Bitcoin miners pivot to AI

NYDIG’s renewed push into Bitcoin mining comes as other miners are increasingly pivoting toward AI and cloud computing as shrinking margins in mining push them to diversify revenue streams.

Earleir this year, MARA Holdings acquired a 64% stake in French infrastructure company Exaion, giving the company a foothold in AI services. Other miners, including Hive, Hut 8, TeraWulf and Iren, are also repurposing mining facilities into data centers, while some, such as CoreWeave, have fully transitioned into AI-focused infrastructure.
