From Aluminum To Bitcoin: Alcoa To Sell Dormant Plant To NYDIG

Bitcoin mining firm NYDIG already has skin in the game at the Massena, New York site — it holds a stake in Coinmint, which runs mining hardware there under a long-term lease. Now the company wants the land itself.

A Deal Years In The Making

Alcoa’s Massena East smelter went dark in 2014 after energy costs climbed and overseas competition cut into margins. The sprawling facility along the St. Lawrence River has sat idle ever since.

Based on reports, Alcoa CEO Bill Oplinger told Bloomberg the two companies are deep in talks and expects a deal to close sometime in the middle of 2026. Financial terms were not disclosed.

For NYDIG, the appeal goes beyond location. Industrial smelters are wired for round-the-clock heavy operations — they come with substations, transmission lines, and grid connections that can handle enormous power loads.

Data center operators and crypto miners often wait years to build that kind of infrastructure from scratch. At Massena, it already exists. The site also draws power from the New York Power Authority’s hydroelectric supply, which cuts costs and reduces the carbon footprint of whatever runs there next.

Old Industry, New Tenants

Massena is not the only shuttered smelter drawing interest from the digital sector. Earlier this year, Century Aluminum sold its Hawesville, Kentucky facility to TeraWulf for $200 million.

TeraWulf plans to turn the site into a high-performance computing and AI campus. Since that deal closed, TeraWulf shares have climbed 80% year-to-date, according to Yahoo Finance data.

The pattern is clear: retired heavy industry sites, long considered liabilities, are being snapped up by firms that need power and space fast. These properties offer something new construction cannot — infrastructure that is already approved, already connected, and already built.

While many miners are shifting toward AI and cloud services to offset shrinking returns, NYDIG is doubling down on Bitcoin.

Last year, the firm — owned by Stone Ridge — acquired Crusoe Energy’s Bitcoin mining operations, including its natural gas flare mitigation business.

The Massena deal, if it closes, would mark another significant step in that direction.

Other players in the space are taking a different road. MARA Holdings picked up a 64% stake in French infrastructure company Exaion to break into AI services. Hive, Hut 8, TeraWulf, and Iren are all converting mining facilities into data centers.

NYDIG, for now, is charting its own course.
