Timeline

Notes

The Lake Mariner campus in Barker, Niagara County is operated by TeraWulf (ticker: WULF) and is TRACKED by Epoch AI as 'Fluidstack Lake Mariner' — the AI/HPC buildings (Buildings 1-5, up to ~459 MW) are leased to Fluidstack for Google TPU deployment serving Anthropic. Queue ID 1670 represents expansion capacity beyond what Epoch currently tracks. TeraWulf's $3.2B financing (October 2025) and Buildings 1-5 timeline confirms the site is actively scaling. This queue entry is the 'Data II' expansion | Matched Epoch facility: Fluidstack Lake Mariner (Epoch ID: data_centers.csv row ~80) | MATCHED to known Epoch facility. Counts in matched_to_known, not as a new discovery. However, the specific 250 MW expansion tranche is beyond Epoch's current tracking scope — relevant as a leading indicator of capacity growth at a known site.
