Name of Action or Project: Lake Hawkeye Data Campus(also referred to as Cayuga Data Campus) Project Location(describe,and attach a general location map): 228 Cayuga Drive,Lansing,NY 14882(see attached site location map) Brief Description of Proposed Action(include purpose or need): The Lake Hawkeye(the"Project")is a data center campus supporting high-performance computing operations located at the former Cayuga power generation site.The Project modernizes an existing utility-scale industrial property into infrastructure that directly supports computing,consistent with the site's historic use as utility-scale infrastructure. The Project will be developed in a staged,modular sequence totaling approximately 300 MW of computing infrastructure.Phase I will consist of the construction of three 50-MW buildings.Phase II will consist of an additional 150 MW of computing infrastructure. This sequential development model mirrors the successful approach implemented at TeraWulf's Lake Mariner campus in Barker,NY,allowing the Project to scale responsibly in alignment with site readiness,final design approvals,and utility interconnection upgrades funded by the Applicants.Each building is anticipated to require approximately 12-14 months from Notice to Proceed through commissioning.Staged deployment ensures continuity of local construction trades, minimizes site disturbance,and enables infrastructure development to advance in a manner consistent with both grid capacity timing and community-facing coordination.
