NYDIG is reportedly close to acquiring Alcoa’s idled Massena East aluminum smelter site in upstate New York, a move that would deepen the firm’s control over one of the more significant hydropower-linked bitcoin mining campuses in North America. According to Bloomberg, Alcoa is in advanced negotiations to sell the property, with the transaction expected to close around mid-2026 if completed.
The site has already been operating as a bitcoin mining campus for years, making this less a speculative greenfield project than a strategic transfer of ownership over an existing industrial-scale digital infrastructure asset. For NYDIG, the deal would fit into a broader pattern of expanding its direct mining footprint across North America.
A Large Existing Campus With Hydropower Access
The Massena East property sits along the St. Lawrence River and is connected to power supplied through the New York Power Authority system, drawing from the Moses-Saunders hydroelectric dam. The campus has approved capacity of roughly 435 MW, although reports indicate it is currently using about 166 MW of that total. The facility is said to house around 54,000 bitcoin mining machines spread across six former aluminum smelting lines.
That industrial legacy is central to the site’s appeal. Former smelters were built to support continuous, high-voltage loads, which means they often retain transmission lines, substations, and other heavy electrical infrastructure that would be difficult and time-consuming to replicate from scratch. For bitcoin miners and data center developers, that can translate into a major advantage in both deployment speed and grid access.
The Massena East property spans approximately 1,300 acres. Alcoa originally idled the facility in 2014, citing high energy costs and global competitive pressures in aluminum production. In the years since, the site has been repurposed for digital infrastructure rather than traditional manufacturing.
NYDIG Already Has a Foothold at the Site
Massena East has functioned as a bitcoin mining campus since 2018, when Alcoa signed a 10-year lease with Coinmint. Coinmint later rebranded its local operating arm as North Country Colocation Services. NYDIG strengthened its position at the site in October 2024 by taking a stake in Coinmint, a move that gave it the ability to deploy its own mining rigs there.
If the reported acquisition goes through, NYDIG would move from being a strategic participant to the direct owner of the property. That distinction matters. Ownership would give the company greater control over site planning, long-term infrastructure decisions, tenant strategy, and the possibility of broader digital infrastructure development beyond hosted mining alone.
Some third-party clients that were once associated with the campus, including Cleanspark, Gryphon, and Bit Digital, have reportedly exited the site. That could leave room for a more centralized operating strategy under NYDIG should the company complete the purchase.
Part of a Broader Mining Expansion Strategy
The reported Massena transaction also fits NYDIG’s wider expansion efforts in physical bitcoin mining infrastructure. In March 2025, the firm reached an agreement to acquire Crusoe Energy’s bitcoin mining business, adding more than 270 MW of operating capacity. Combined with other mining assets acquired in 2024, a purchase of Massena East would further consolidate NYDIG’s position in the North American mining market.
Rather than simply financing mining operations or holding indirect exposure through investments, NYDIG appears to be increasing its ownership of real-world infrastructure. That can be strategically important in a market where energy access, interconnection timelines, and regulatory certainty often matter as much as hardware efficiency.
The Massena site offers exactly the kind of industrial platform that has become increasingly attractive: a large footprint, existing electrical systems, a proven operating history, and access to low-carbon hydropower. Those characteristics are difficult to replicate with new construction, especially in regions where transmission constraints or permitting delays can slow projects for years.
Why Former Smelters Are Becoming Digital Infrastructure Hubs
One of the clearest themes in this deal is the growing repurposing of legacy industrial facilities for bitcoin mining and data center use. Aluminum smelters in particular were built for energy-intensive continuous operations, making them uniquely compatible with large-scale computing loads. Instead of building a new site from the ground up, operators can reuse power infrastructure that was already designed for utility-scale demand.
This reduces development complexity and may also improve the economics of deployment. The article notes that reusing existing hydropower-linked infrastructure avoids the need for new power plant construction. That has drawn interest from operators focused on lower-carbon digital infrastructure, especially as environmental scrutiny around mining energy sources remains a key industry issue.
The Massena East deal follows a similar industrial repurposing trend elsewhere in the United States. Century Aluminum, for example, previously sold its Hawesville, Kentucky smelter to Terawulf for roughly $200 million in cash and equity for digital infrastructure use. These transactions suggest that dormant heavy-industrial properties are increasingly being revalued as strategic power-connected sites for computing rather than manufacturing.
Alcoa’s Divestment Plan and Local Impact
For Alcoa, the potential sale is part of a broader effort to divest dormant U.S. smelter properties. CEO Bill Oplinger said the company has been offering roughly 10 inactive sites to data center developers and crypto miners seeking large, pre-wired industrial locations with utility-scale power access. The company has not disclosed financial terms for the Massena East transaction.
Oplinger reportedly confirmed in an April 17, 2026 interview that Alcoa was in advanced-stage discussions and expected the transaction to close around the middle of the year. During the company’s first-quarter 2026 earnings call on April 16, he described the prospective buyer as a prior partner at the site working on a data center project, a description consistent with Bloomberg’s identification of NYDIG.
The existing mining operation at Massena employs about 85 full-time workers across Massena and Plattsburgh. Expansion under NYDIG ownership is expected to increase that workforce. Local authorities have already adjusted regulations to accommodate cryptocurrency and data mining operations, suggesting the town is preparing for continued digital infrastructure development rather than treating it as a temporary use case.
What the Deal Could Mean
If completed, the acquisition would give NYDIG direct ownership of a hydropower-connected mining campus where it already has an established operational presence. It would also reinforce a broader market shift in which bitcoin mining companies and digital asset firms are moving beyond short-term hosting arrangements toward deeper control of power-rich industrial real estate.
While the price of the transaction remains undisclosed, the strategic logic is relatively clear. In a sector where reliable electricity, existing interconnection, and large-scale industrial zoning are scarce advantages, Massena East is more than a former smelter. It is a ready-made platform for long-duration bitcoin mining and potentially wider data center development. For NYDIG, that could make the site an important cornerstone in its next phase of infrastructure growth.
