Alcoa in Talks to Sell Idle New York Smelter to Bitcoin Mining Firm NYDIG

Alcoa, the largest aluminum producer in the United States, is reportedly close to offloading its dormant Massena East smelter in upstate New York to bitcoin mining company New York Digital Investment Group (NYDIG). CEO Bill Oplinger confirmed the company is in advanced negotiations and anticipates the transaction will be finalized sometime in mid-2025.

The Massena East facility has remained inactive since 2014, when Alcoa shuttered operations due to rising costs and mounting pressure from global competition. While the site no longer produces aluminum, its industrial infrastructure tells a different story — one that is increasingly attractive to the digital economy.

What makes the property valuable is not its legacy as a metals plant but the energy infrastructure left behind. Industrial smelters consume massive amounts of electricity and are engineered with heavy-duty substations and dedicated power transmission systems capable of running continuously. When these facilities close, that grid-ready infrastructure stays in place, making them prime candidates for energy-intensive operations like cryptocurrency mining and artificial intelligence data centers.

Massena East adds another layer of appeal through its access to clean, low-cost hydropower supplied by the New York Power Authority — a critical advantage for bitcoin miners and tech firms under growing pressure to demonstrate sustainable energy use.

The deal also signals an accelerating trend of repurposing shuttered heavy industry sites for digital infrastructure. Earlier this year, Century Aluminum completed a similar transaction, selling a former Kentucky smelter to bitcoin miner TeraWulf, which plans to develop a high-performance computing and AI campus on the grounds.

As demand for grid capacity intensifies across the data center and crypto mining sectors, legacy industrial sites with existing power access are emerging as some of the most sought-after real estate in the digital age.
