Alcoa is currently in negotiations to sell its Massena East aluminum smelter, located in upstate New York, to NYDIG, a firm specializing in bitcoin financial services. This discussion was revealed by Alcoa’s CEO, Bill Oplinger, during an interview with Bloomberg. The Massena East site has been idle since 2014, a closure attributed to the mounting pressures of high energy costs and intensified global competition, which have adversely affected domestic aluminum production.
Spanning approximately 1,300 acres along the St. Lawrence River, the facility boasts significant electrical infrastructure originally designed for continuous industrial use. The potential sale is part of a broader strategy by Alcoa to divest from several underperforming smelting assets in the United States. The company has pinpointed ten unused sites for sale as it pivots towards higher-margin operations and seeks to diminish its reliance on costly legacy facilities. With the Massena East property positioned as one of its most advanced divestiture cases, Alcoa is poised to shift its focus effectively.
NYDIG has been steadily expanding its footprint in industrial-scale bitcoin mining over the past two years through a series of partnerships and acquisitions, previously collaborating with Coinmint at the Massena campus under a long-term lease tied to the site’s available power capacity. The smelter’s electrical connection to the New York Power Authority’s hydropower system provides a stable supply of electricity, which is crucial for digital asset mining operations. Given that aluminum smelting requires substantial and consistent energy input, the existing grid connections often remain intact post-closure, facilitating their repurposing into data centers or mining facilities.
NYDIG holds a strategic interest in Coinmint, which operates bitcoin mining equipment at the larger Massena facility, benefiting from earlier agreements linked to Alcoa’s property and power setup. The planned transaction would formally transfer control of the smelter site to NYDIG, enhancing its operational capabilities in the region. Both parties are currently discussing the terms of a transfer structure that would encompass ownership of the land, electrical systems, and any remaining industrial assets. The goal is to finalize the transaction by mid-year, pending necessary agreements and regulatory approvals.
This proposed sale aligns with a growing trend in North America where retired aluminum smelters and other heavy industrial sites are transitioning towards digital infrastructure uses. These locations offer extensive power connections, transmission access, and industrial zoning, making them ideally suited for bitcoin mining and high-performance computing applications. A similar transaction was recently executed by Century Aluminum, which sold its Hawesville, Kentucky smelter to TeraWulf for redevelopment into a data center and computing campus, reflecting a notable demand for sites with reliable energy capacity.
As NYDIG continues to bolster its position in the bitcoin mining sphere through acquisitions in various states—including North Dakota, South Dakota, Pennsylvania, and Missouri—the completion of the Alcoa-NYDIG deal would result in one of the largest former aluminum production sites being repurposed for bitcoin mining, thereby extending the legacy industrial power infrastructure into new digital asset operations.
