Cayuga Data Campus (former Cayuga Operating Company power plant site)
Tompkins County
Description
TeraWulf wants to build a 400 MW AI data center at the old Lansing coal plant, and its affiliate is seeking to modify — rather than renew from scratch — a permit to withdraw over a million gallons a day from Cayuga Lake. The Legislature asked the DEC to require a brand-new permit with full environmental review.
Impact summary
The project could draw massive amounts of lake water and grid power; residents fear warmer discharges, algal blooms, and higher electric bills, while supporters note it would open the waterfront to the public.
