NYDIG acquires Alcoa’s idle aluminum smelting plant, firmly betting on Bitcoin mining

According to Bloomberg, U.S. aluminum company Alcoa plans to sell its idle aluminum smelting plant in Massena, New York, to Bitcoin mining company NYDIG. The plant was shut down in 2014 due to rising energy costs and overseas competition and has remained idle since.

Alcoa CEO Bill Oplinger told Bloomberg that the two companies are engaged in in-depth negotiations regarding the acquisition. The deal is expected to be completed in mid-2026, but financial terms were not disclosed.

For NYDIG, the appeal of this transaction lies not only in its location, but also in the smelting plant itself having the power infrastructure required for round-the-clock heavy operations— including substations, transmission lines, and high-load grid connections.

Data center operators and crypto mining firms typically need years to build out such infrastructure, but these facilities in the state are already in place. In addition, the site is supplied with hydroelectric power by the New York Power Authority, which both lowers operating costs and reduces its carbon footprint.

Massena is not the only idle smelting plant drawing attention from digital industries. Earlier this year, Century Aluminum sold its plant in Hawesville, Kentucky, for 200 million to TeraWulf, which plans to transform it into a high-performance computing and AI park.

Current market trends suggest that potential decommissioned heavy industrial sites—long seen as liabilities—are being snapped up by companies that urgently need electricity and space. Because these asset advantages are clear: construction approvals are already in place, power has already been connected, and infrastructure has already been built.

Although many miners have shifted toward AI and cloud services to offset declining earnings, NYDIG remains steadfast in its bet on Bitcoin. If the Massena deal is successfully completed, it will mark another key step for NYDIG in the Bitcoin space.

In summary, during the industry’s transition period, NYDIG chooses to stick to the Bitcoin mining track, gaining a cost advantage by acquiring existing infrastructure, demonstrating its differentiated strategic layout.

Looking ahead, as more decommissioned heavy industrial sites are reactivated by digital industries, this “old bottle, new wine” model may become a new trend in industry development.
