NYDIG is reportedly in the final stages of negotiations to acquire Alcoa’s idled Massena East aluminum smelter site in northern New York, a move that would significantly deepen the company’s direct exposure to large-scale bitcoin mining infrastructure. According to Bloomberg, the transaction could close around mid-2026, although financial terms have not been disclosed.
The potential acquisition would give NYDIG full ownership of a site that has already been repurposed into a substantial bitcoin mining campus. The facility carries an approved power capacity of about 435 megawatts and is tied to hydroelectric supply in the St. Lawrence River corridor, making it one of the more strategically positioned legacy industrial sites for high-load digital infrastructure in the region.
A Former Smelter Turned Mining Campus
Massena East has not operated as an aluminum smelter for years. Alcoa shut the facility in 2014, citing high energy costs and global competitive pressures. But the site’s industrial legacy is precisely what makes it valuable today. Built for energy-intensive aluminum production, the property retained the substations, transmission links, and heavy-duty electrical infrastructure needed to serve continuous, high-voltage loads.
That existing grid setup has helped transform the campus into a bitcoin mining operation. Since 2018, the property has functioned as a mining complex under a long-term lease with Coinmint, which later rebranded its local operating presence as North Country Colocation Services. NYDIG strengthened its position at the site in October 2024 by investing in Coinmint, a step that enabled it to deploy its own mining machines there.
Bloomberg’s report indicates the campus currently uses around 166 MW of its approved 435 MW capacity and houses roughly 54,000 bitcoin miners spread across six former aluminum production lines. Several third-party customers, including Cleanspark, Gryphon, and Bit Digital, have reportedly exited the site, potentially making it easier for NYDIG to consolidate operations under its own ownership and strategy.
Why Legacy Industrial Sites Matter for Bitcoin Mining
The Massena East case reflects a broader trend across North America: bitcoin miners and data center developers are increasingly targeting retired industrial assets rather than starting from scratch. Old smelters and similar heavy-industry sites were originally designed for uninterrupted power consumption at industrial scale. That leaves behind electrical systems that would be expensive, slow, and often difficult to recreate today.
For digital infrastructure operators, the advantage is not just raw power availability but time. New grid interconnection projects can face multi-year delays. A legacy site with existing substations and transmission access can shorten that timeline dramatically. In an environment where power access has become one of the most important constraints on mining expansion, those characteristics can make a former industrial property more attractive than undeveloped land.
Massena East appears to fit that pattern closely. The property spans roughly 1,300 acres and draws electricity through the New York Power Authority system, linked to the Moses-Saunders hydroelectric dam on the St. Lawrence River. The hydro connection adds another layer of appeal, especially for operators focused on lower-carbon energy sourcing and ESG-sensitive infrastructure narratives.
NYDIG’s Broader Mining Expansion Strategy
The reported Massena deal would not be an isolated move. NYDIG has been steadily increasing its physical bitcoin mining footprint in North America. In March 2025, the company reached an agreement to acquire Crusoe Energy’s bitcoin mining business, adding more than 270 MW of operating capacity. Combined with other mining-related assets acquired in 2024, the Massena purchase would further shift NYDIG toward direct ownership of large-scale mining infrastructure.
That matters strategically. Owning the real estate and power-linked industrial base of a mining campus provides a different degree of control than simply colocating machines or holding a financial stake in an operating partner. It can give a company more influence over deployment schedules, operational design, customer mix, and long-term power planning. In Massena’s case, NYDIG would be moving from a strategic investor and on-site participant to the outright owner of a facility it has already been involved with for more than a year.
The site also includes an operating workforce. Current mining activities in Massena reportedly employ about 85 full-time staff across Massena and Plattsburgh. The report suggests that expansion under NYDIG ownership could increase headcount, with local authorities in the Town of Massena having already updated regulations to better accommodate cryptocurrency mining and data operations.
Alcoa’s Asset Divestment and the New Market for Old Smelters
For Alcoa, the proposed sale fits into a broader effort to divest inactive U.S. smelter properties. CEO Bill Oplinger said the company has been marketing roughly 10 idle smelter sites to data center developers and cryptocurrency miners looking for large industrial parcels with pre-installed electrical systems and grid-scale connectivity. In that context, Massena East is not simply a one-off transaction but part of a larger industrial transition underway in the United States.
Oplinger confirmed in an interview on April 17, 2026 that negotiations over the site were in the final stage. He had also described the prospective buyer during Alcoa’s first-quarter 2026 earnings call as a previous partner at the site involved in a data center-related project, a description consistent with Bloomberg’s identification of NYDIG as the likely acquirer.
Alcoa did not release pricing details. Still, the sale discussion surfaced alongside strong quarterly financial results. The company reported $425 million in net income and $595 million in adjusted EBITDA for the first quarter of 2026, with aluminum prices helping drive performance.
A Wider Shift Toward Digital Infrastructure Reuse
The possible NYDIG-Alcoa transaction also follows another notable industrial conversion in the sector. Century Aluminum previously sold its Hawesville, Kentucky smelter to Terawulf in a transaction valued at roughly $200 million in cash and stock for digital infrastructure use. Together, such deals highlight a developing pattern: retired metallurgical and industrial properties are increasingly being repositioned as bitcoin mining campuses or data center hubs.
Supporters of this model argue that it makes practical use of existing high-load energy infrastructure without requiring entirely new power plants to be built. In Massena’s case, the use of existing hydroelectric-linked capacity may strengthen the site’s appeal to operators seeking to scale digital infrastructure while emphasizing lower-emission power sources.
If the transaction closes as expected, NYDIG would gain direct control over one of the better-known repurposed industrial mining sites in New York. More broadly, the deal would underscore how access to power-ready real estate is becoming one of the defining competitive factors in the bitcoin mining industry. As grid access tightens and project timelines stretch, former heavy-industry properties like Massena East are increasingly becoming prime real estate for the next phase of digital asset infrastructure growth.
