NYDIG is reportedly in advanced talks to acquire Alcoa Corp.’s idle Massena East aluminum smelter site in northern New York, a move that would deepen the firm’s control over a major bitcoin mining and digital infrastructure campus. According to a Bloomberg-cited report, the transaction could close around mid-2026, although financial terms have not been disclosed.
If completed, the acquisition would give NYDIG full ownership of a site where it already has a strategic presence. The development fits into a broader industry pattern in which former heavy-industrial properties, particularly old smelters with substantial power infrastructure, are being repurposed for bitcoin mining and data center use.
A Large Hydro-Connected Mining Campus
The Massena East property is one of the more notable industrial-to-digital conversions in the U.S. The campus sits along the St. Lawrence River and draws electricity through the New York Power Authority, with power linked to the Moses-Saunders hydroelectric dam. The site has an approved electrical capacity of roughly 435 megawatts, making it highly attractive for power-intensive digital operations.
According to the report, the facility is currently consuming about 166 megawatts and houses around 54,000 bitcoin mining machines. Those machines are spread across six former aluminum potlines, underscoring how legacy industrial buildings can be adapted for modern computing infrastructure. The ability to access existing substations, transmission lines, and utility-scale interconnection has become one of the main reasons former smelter properties are drawing interest from miners and data center operators.
For developers, that existing infrastructure can provide a major time advantage. Rather than waiting years for a new grid connection, buyers can reuse electrical systems originally built for continuous, high-load industrial production. In a market where power availability often determines whether a mining or compute project is viable, that infrastructure can be more important than the buildings themselves.
NYDIG’s Existing Footprint at Massena
The Massena East campus has been operating as a bitcoin mining site since 2018, when Alcoa signed a 10-year lease with Coinmint. Coinmint later rebranded its local operations under the name North Country Colocation Services. NYDIG expanded its involvement in October 2024 by taking a stake in Coinmint, a step that gave it the ability to deploy its own mining rigs at the site.
That prior investment makes the current reported acquisition especially significant. Rather than remaining an investor or strategic participant, NYDIG would move to direct ownership of the campus. Such a transition would likely give the company greater control over operating strategy, power allocation, tenant relationships, and future development plans tied to mining or broader data infrastructure.
The report also noted that several third-party clients had previously used the site, including Cleanspark, Gryphon, and Bit Digital, though some of those customers have since departed. A full acquisition by NYDIG could simplify the site’s long-term operating structure and allow it to align the campus more directly with its own infrastructure priorities.
Part of a Wider Expansion Strategy
The potential Massena transaction follows another major NYDIG expansion step. In March 2025, the company reached an agreement to acquire the bitcoin mining business of Crusoe Energy, adding more than 270 megawatts of operational capacity. Combined with other mining assets acquired across North America in 2024, the Massena East deal would strengthen NYDIG’s position as an owner and operator of physical mining infrastructure rather than only a financial or service-layer participant in the digital asset ecosystem.
This strategy suggests that NYDIG sees long-term value in controlling hard assets tied to power, land, and interconnection rights. In the mining business, access to low-cost and reliable electricity remains a central competitive factor. Owning sites with prebuilt utility infrastructure can offer strategic flexibility that is difficult to replicate through leasing arrangements alone.
Why Former Smelters Are in Demand
Massena East highlights a broader structural shift now underway in parts of the U.S. industrial economy. Aluminum smelters were historically among the most electricity-intensive manufacturing facilities in operation. As some plants shut down due to higher energy costs and global competition, their grid-ready footprints became attractive to new users that also require large, steady power loads.
Alcoa originally idled the Massena East facility in 2014, citing high energy costs and competitive pressure. The property spans about 1,300 acres and still contains the electrical infrastructure built for large-scale aluminum production. That makes it a rare asset in a market where utility-scale power access is constrained and increasingly sought after by sectors ranging from bitcoin mining to AI and traditional data center development.
Alcoa executives have indicated that the company is pursuing monetization of roughly 10 idle U.S. smelter sites. Management has framed these properties as appealing to data center developers and crypto miners looking for large industrial parcels that are already wired and connected to the grid at scale. The reported Massena deal appears to be one of the clearest examples of that strategy moving toward completion.
Local Employment and ESG Angle
The existing mining operation in Massena currently supports about 85 full-time employees across Massena and Plattsburgh, according to the report. Expansion under NYDIG ownership could increase that workforce, particularly if the company broadens the site’s role beyond its current deployment levels. The town of Massena has already updated local rules to better accommodate cryptocurrency and data mining activity, signaling a degree of institutional adaptation to the site’s new industrial identity.
The hydro-linked power supply also gives the campus a distinct profile in ESG-related discussions. Because the site is using existing hydroelectric capacity rather than relying on a newly built fossil-fuel power source, it may appeal to operators seeking lower-carbon digital infrastructure. That does not end debate around bitcoin mining and energy usage, but it does help explain why hydro-connected industrial campuses are attracting sustained interest.
A parallel example came from Century Aluminum, which sold its Hawesville smelter in Kentucky to Terawulf for about $200 million in cash and equity for digital infrastructure use. Taken together, these transactions suggest that idled industrial energy assets are being revalued as strategic platforms for high-density computing.
Alcoa’s Financial Backdrop
The reported sale discussions emerged alongside strong quarterly results from Alcoa. The company posted $425 million in net income and $595 million in adjusted EBITDA for the first quarter of 2026, supported by aluminum prices. While the company did not disclose pricing for the Massena East transaction, the timing suggests Alcoa is pursuing asset monetization from a position of operational strength rather than distress.
For NYDIG, the possible purchase would represent another step in building out a power-centered digital infrastructure portfolio. For Alcoa, it would be part of a broader effort to unlock value from dormant industrial properties. And for the bitcoin mining industry more broadly, it would reinforce a trend that may shape the next phase of capacity growth: converting legacy heavy-industrial sites into energy-rich computing campuses.
