# Anthropic Lake Mariner

Facility record `fac-epoch-anthropic-lake-mariner` — data source: Epoch AI — frontier data centres (https://epoch.ai/data/data-centers); authority tier 2; contains estimated values (is_estimated: true)

| Field | Value |
| --- | --- |
| Type | AI Training |
| Status | Operational |
| Location | Town of Somerset, New York, US (43.358206, -78.600819) |
| Location basis | The record's coordinates fall in Town of Somerset, Niagara County, New York \(U.S. Census Bureau boundaries as of 1 January 2026, read 30 October 2026\). |
| Location in the source's words | 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” \(download of 30 October 2026\). |
| Facility power | 49 MW; counted in operating totals; recorded-power totals count this campus once, using TeraWulf Lake Mariner Campus. |
| Power is operating capacity | yes (a reviewed present figure) |
| IT load | 42 MW |
| GPU count | not published |
| H100-equivalents | 58,564 |
| Peak PFLOPS (FP16) | not published |
| Site owner | The site owner is unrecorded. |
| Site operator | No organisation is recorded as operating this site. |
| AI hardware owner | AI XPV Platform |
| Announced | not published |
| Operational | not published |

## Role evidence

Each role is stated only as the relationship its own source establishes.

- **AI hardware owner: AI XPV Platform.** Epoch AI's field for who owns the AI hardware, which it defines as not necessarily the owner or operator of the facility. “Owner: AI XPV Platform \#confident” [Source](<https://epoch.ai/data/data-centers>)

## Organisations recorded at the site

### Anthropic — Uses the compute \(source marks likely\)

Named in Epoch AI's field for labs using the compute; it records use, not a lease.

The relationship is inferred.

Recorded start date: not stated. Recorded end date: not stated.

## Campus: TeraWulf Lake Mariner, Somerset, NY

These records describe the same physical site at different scopes, and their power figures are never added together. Across the platform, recorded totals count the canonical member once; operating totals count a member's figure only if it is operating capacity.
Note: Three records describe the Lake Mariner campus. Recorded totals use the 510 MW figure, the build-out of the five AI buildings, not the plant running today. Operating totals use Epoch's estimates for the two tenants' buildings instead: 58 MW leased to Core42 and 49 MW leased to Fluidstack. TeraWulf reported 102 MW of critical IT capacity online and 336 MW more under construction on 5 August 2026.

| Member | Status | Scope | Power (MW) | Operating capacity | Canonical for power | Source |
| --- | --- | --- | --- | --- | --- | --- |
| [TeraWulf Lake Mariner Campus](https://scrutica.com/facilities/fac-epoch-fluidstack-lake-mariner) | Operational | full build-out | 510 | no (campus build-out figure on an operating site) | yes | Epoch AI Frontier Data Centers |
| [Core42 Lake Mariner](https://scrutica.com/facilities/fac-epoch-core42-lake-mariner) | Operational | current deployment | 58 | yes | no | Epoch AI Frontier Data Centers |
| [Anthropic Lake Mariner](https://scrutica.com/facilities/fac-epoch-anthropic-lake-mariner) | Operational | current deployment | 49 | yes | no | Epoch AI Frontier Data Centers |

## Data-quality flags

- 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 49 MW, Epoch's estimate for the one building of three leased to Fluidstack now running. Recorded totals use the campus's 510 MW build-out figure, which includes it.
