Source-reported capacity; not metered consumption. Review underlying documents and notes. Planned capacity may include future phases and is not added to operational capacity here. The source may use facility, grid-feed or IT capacity definitions; consult the linked documents.

Coordinate precision is a source label, not an independent parcel survey. A marker does not confirm utility territory or establish an effect on residential bills.

Source notes

Site is the former Cayuga Power Plant (coal-fired, retired). NYSDEC water permit application for Cayuga Lake withdrawal was originally filed in 2021 for 'unspecified future use.' Permit dates to 1955 without modern monitoring requirements per opposition. TeraWulf also has a separate cryptomining operation at the Susquehanna site in PA (Nautilus). Operating entity: Cayuga Operating Company (acquired plant). No status change. The April 2026 DEC water-withdrawal/SPDES action is explicitly for the existing power plant's current operations, not the data center; DEC states it is 'not associated with the proposed data center'. As of the sources fetched 2026-09-09 the project remains proposed and had not cleared local site-plan review. Do not read the water permit as a data-center permit.

Former Cayuga Power Plant (coal) site at 228 Cayuga Drive on Cayuga Lake shoreline; 80-year lease signed August 2025.
