Ownership roles. Title identifies the legal owner of the site; operation identifies who runs it. AI-hardware ownership follows the catalog’s attribution of the machines inside, whose owner may lease the facility. Each role requires its own attribution. An operator named in a source supplies evidence of operation only, and no role implies exclusive control of the full site.
Parent companies. Ownership checks start with each company named at the site and follow recorded parent relationships. A company holding several roles is checked once. Its linked company page lists the relationships and their sources; further parents may remain undocumented. Level 1 identifies a company at the site, level 2 its parent, and each further level another parent. Export-control designations and government investments are assigned to the company concerned.
Missing values. Unrecorded roles remain blank. Findings whose company position is unresolved stay in the list with that position labelled unknown.
Location. The record's coordinates fall in Town of Somerset, Niagara County, New York (U.S. Census Bureau boundaries as of 1 January 2026, read 30 October 2026). Epoch AI Frontier Data Centers gives the address as “7725 Lake Rd, Barker, NY 14012”, the city as “Barker” and the state as “New York” (download of 30 October 2026).
Data quality. This record’s power figure is withheld from recorded-power totals so the campus counts once; operating totals count it, as the campus’s reviewed current deployment. Curator’s working note: Part of the TeraWulf Lake Mariner campus. Operating totals count this record's 58 MW, Epoch's estimate for the two buildings leased to Core42. Recorded totals use the campus's 510 MW build-out figure, which includes it.
Publication limits. Subscription corporate data helps identify parent relationships and sovereign investments. Publication is limited to relationship classes and supporting public sources; licensed records, identifiers and values are withheld. Per-fund identities and amounts are withheld.
Epoch AI estimates capacity using satellite imagery, permits and corporate disclosures. Its catalog is the source for this site record.
Figures from Epoch AI Frontier Data Centers retain the source’s estimate flags.
