TeraWulf’s Lake Mariner data center fire raises safety concerns Firefighters responding to a June fire at TeraWulf's Lake Mariner data center campus in Somerset, New York found no working fire alarm, no suppression system, and three non-functional hydrants, according to Fire Chief Steve Matisz, who said his crew entered the building 'kind of blind.' TeraWulf, which is pivoting the former Bitcoin mining facility toward AI and high-performance computing with a target of 500 to 750 MW by end of 2026, claimed safety data sheets were destroyed in the blaze, and no regulatory follow-up has been publicly reported. TeraWulf official simplified logo terawulf.com TeraWulf’s Lake Mariner data center fire raises safety concerns Firefighters responded to the blaze with no working alarms, no suppression systems, and three dead hydrants at the former Bitcoin mining facility turned AI hub When firefighters from the Barker Fire Department arrived at TeraWulf’s Lake Mariner data center campus in Somerset, New York in early June, they found themselves in a situation no first responder wants to face. No functioning fire alarm. No suppression system. Three hydrants that didn’t work. And the safety data sheets that would have told them what chemicals were producing the heavy black smoke filling the unfinished building had, according to TeraWulf, burned up in the fire itself. Fire Chief Steve Matisz said his crew went into the building “kind of blind.” He added he wasn’t sure what to think about the claim that the safety sheets had been destroyed in the blaze. “It’s been a difficult situation,” Matisz said. A campus in transition, and apparently in disarray The Lake Mariner campus sits on the site of a retired coal plant in upstate New York, a location TeraWulf began operating in 2022 primarily for Bitcoin https://cryptobriefing.com/markets/bitcoin/ mining. The company has been aggressively pivoting the facility toward artificial intelligence and high-performance computing workloads. TeraWulf has been targeting a combined capacity of 500 to 750 MW across several buildings by the end of 2026. Tenants at the campus include Core42 and Fluidstack, both linked to tech operations supported by Google https://cryptobriefing.com/markets/alphabet/ credit. The fire broke out in a building that was still under construction. Post-incident discussions reportedly included plans for additional hydrants and better storage protocols for safety data sheets. The regulatory silence Perhaps the most unsettling detail isn’t the fire itself but what happened afterward, which appears to be very little. No regulatory follow-ups or investigative actions have been publicly reported in relation to the incident. From Bitcoin to AI, same infrastructure risks TeraWulf’s pivot from Bitcoin mining to AI and HPC leasing is a strategic bet that many former crypto miners are making. The company’s stock trades on Nasdaq under the ticker WULF. Landing tenants like Core42 and Fluidstack validates the commercial logic of repurposing crypto mining infrastructure for broader compute workloads.
