A fire at the Lake Mariner project highlighted unclear lines among the site owner, operator, financier and AI customer. A fire broke out in June in an unfinished building at the Lake Mariner data center. Local firefighters reported that they encountered no working alarm, no suppression system and three dry hydrants.
No one was injured in the fire. The campus is valued at about $3.2 billion and is being built on a former coal site in Somerset, New York. The Lake Mariner data center in Somerset, New York, is a $3.2 billion project involving TeraWulf, Fluidstack, Google and Anthropic. A June fire raised questions about emergency systems and which company is responsible for correcting failures.
TeraWulf owns and operates the data center, while Fluidstack plans to run computing operations. Google holds warrants for a future 14 percent stake and guarantees Fluidstack lease payments; Anthropic is among the expected compute users. TeraWulf later said it was responsible for operational safety and emergency preparedness.
The company reported adding Knox boxes, hydrants and portable safety-data materials after an after-action review. New York lawmakers passed a data-center bill that includes environmental, labor, energy and community provisions, though its final legal status was still developing. Technical capability, institutional policy and reported observation are kept distinct in the account.
The evidence available for this dated edition has a defined boundary: The account reflects reporting and statements from parties with different roles; not every disputed safety condition had been independently resolved. Further reporting is expected on inspection results and confirmation that hydrants and suppression systems are operational and state action on the proposed data-center requirements.
