Coinmint (Massena East / former Alcoa Smelter)

Opposition and litigation at this site

Nothing on record as of September 10, 2026. No lawsuit, organized opposition, or contested hearing over Coinmint (Massena East / former Alcoa Smelter) in Massena, St. Lawrence County, New York appears in the sources this registry tracks. That is an absence in our sources rather than a finding that none exists, and local opposition often predates any coverage a national dataset would pick up.

If you live near this site and something is happening that this page does not show, that is worth telling us. Send us the document and it goes in the record with the source attached. For sites where opposition is already established, see every contested site we track.

Power and water

NYPA trustees approved a conditional 15,000 kilowatt (15 MW) power allocation to the data center per a Jan. 30, 2018 NYPA memorandum -- this is an allocation approval, not a confirmed on-site generation figure, and predates the facility's later expansion to ~435 MW capacity reported elsewhere.

Notes on the record

Former Alcoa East aluminum smelter, ~1,300 acres, adjacent to the Moses-Saunders Power Dam on the St. Lawrence River, no confirmed street address exists in public sourcing, so coordinates here are Massena, NY's town center, not the facility's actual footprint (approximate, per location.precision). Substation approved for 435 MW; operational draw was last publicly reported at 166 MW as of late 2024 (~38% utilization), treat as a last-known figure, not current, since ~110 MW of third-party colocation (CleanSpark, Gryphon, Bit Digital) was reported vacating around early 2025 and actual current draw is likely lower. Ownership is in transition: NYDIG holds a strategic stake from an Oct 2024 investment, and Alcoa's CEO confirmed (Apr 17, 2026) advanced negotiations to sell the site outright to NYDIG, expected to close around Q3 2026 pending regulatory approval, operator recorded here as Coinmint since the sale has not closed. energy DELIBERATELY NOT FILLED. It is tempting to record energy.source='hydro' for a St. Lawrence-adjacent site at a former aluminium smelter, but the only source I could fetch states explicitly that a hydro PPA is UNCONFIRMED. Recording 'hydro' here would be inference, not evidence. The resolving document would be an NYPA trustee resolution naming North Country Data Center Corporation and a megawatt allocation; I was not able to fetch NYPA's trustee minutes in this run.

Distances are between recorded coordinates, many of which are a city or county centroid, so treat them as approximate. Cumulative load on one utility and one aquifer is the question a planning commission rarely asks.
