United States · 1 project · Last reported
Summary
TeraWulf plan to redevelop about 183 leased acres of the former coal-fired Cayuga power plant site on Cayuga Lake in Lansing, Tompkins County, New York, into a high-performance computing campus. Its 80-year ground lease, announced in August 2025, gives exclusive rights to develop up to 400 MW, and TeraWulf first expected 138 MW online in late 2026. That timeline slipped: the project was in town site plan review in May 2026, faced county and resident opposition, and by August 2026 TeraWulf called it a longer-term redevelopment of about 400 MW gross, 320 MW of critical IT load, with operations not expected before about 2029.

Power supply
| Type | Description | Sources |
|---|---|---|
| Solar | TeraWulf said in August 2025 that a solar installation of about 67 MW was planned, without saying where. | TeraWulf |
| Battery storage | An 800 MWh battery storage system was in advanced development on adjacent parcels, per TeraWulf in August 2025. | TeraWulf |
Capacity figures shifted across TeraWulf releases: 138 MW for 2026 (August 2025), about 150 MW then 300 MW in two phases (May 2026), and about 400 MW gross and 320 MW IT longer term (August 2026). Local reporting says TeraWulf has pledged not to use lake water for cooling but has applied to renew a water withdrawal permit. WBNG dates the original lease rights to 2019, while TeraWulf announced the ground lease in August 2025.

Evidence
Sources are linked, not redistributed; each keeps its own terms. An archived copy is a lookup for the Wayback Machine capture nearest the retrieval date and may be unavailable or differ from what was reviewed. Each hash states what it covers; imported factual records are not publisher-page captures.
