Who's Liable When AI Data Centers Fail? A $3.2B Case Study

A June fire at the Lake Mariner data center in Somerset, New York revealed a troubling reality about the AI infrastructure boom: when something goes wrong, determining who bears responsibility can be nearly impossible.

Firefighters responding to the blaze at the still-under-construction facility encountered no working alarm system, no fire suppression equipment, and three non-functional hydrants. Safety documents legally required to be available had reportedly burned in the fire itself. Steve Matisz, chief of the Barker Fire Department, said his crew went in "kind of blind," facing heavy smoke from unidentified chemicals.

The incident highlights a structural problem that extends far beyond one facility. Lake Mariner's $3.2 billion campus involves at least five major stakeholders: TeraWulf owns and operates the site on land leased from a company owned by its own CEO; UK-based Fluidstack will run the center; Google holds warrants for future 14 percent equity and guarantees lease payments; and Anthropic is among the AI companies the facility will serve.

Why it matters

As AI companies race to build computing capacity, they're creating ownership structures so complex that basic questions—who fixes the hydrants, who verifies clean energy claims, who meets with concerned residents—have no clear answer. This diffusion of responsibility creates gaps where safety, environmental, and community obligations can fall through entirely.

Promises versus reality

The accountability problem extends beyond emergency response. According to a 2024 planning presentation, TeraWulf's project manager said the completed facility would employ 35 to 40 people for a 500-megawatt operation. That figure represents a fraction of the 165 permanent jobs and $85 million in capital investment promised in 2019 when the site applied for power discounts.

New York Governor Kathy Hochul acknowledged the pattern in July, telling reporters that "despite the scale of these projects and the utility demands, data centers do not deliver significant, long-term jobs." She has since placed a moratorium on hyperscaler data center development.

Pilar Thomas, who teaches Tribal energy law and formerly worked at the Department of the Interior, described the typical employment trajectory bluntly: "It's 600 people building the project for six, 12, 18 months... And then after that it's three guys and a bottle of Windex."

The clean energy verification gap

TeraWulf's environmental claims have also shifted. Its 2024 corporate social responsibility report described Lake Mariner as powered by "95 percent zero-carbon energy." The company's April 2026 sustainability policy no longer uses "zero-carbon" alone, instead referencing "low- and zero-carbon energy sources." A separate 2025 disclosure puts the figure at 91 percent "low-carbon energy."

Kerri Langlais, TeraWulf's chief strategy officer, explained the claim rests on the regional grid mix, not contracts tied to specific power sources. The facility draws from a grid that was 87 percent zero-emission in 2025, primarily nuclear and hydroelectric. Critically, TeraWulf purchases no renewable energy certificates to verify these claims.

Neither Anthropic nor Google—despite their financial stakes—appears able to confirm how much of Lake Mariner's electricity actually meets clean energy standards. A source familiar with Anthropic's approach said the company did not have details on what it would need to see from partners to verify commitments or whether it had ever asked.

Regulatory gaps

When federal regulators reviewed TeraWulf's purchase of a Maryland power plant, they were asked whether Google's warrant stake should have been disclosed. TeraWulf argued unexercised warrants confer no ownership or control and therefore required no disclosure. Regulators agreed, despite opposition from Public Citizen, the NAACP, and independent market monitors.

Tyson Slocum, Public Citizen's energy program director, called it "a pretty big loophole" that a company can have rights to acquire 14 percent of shares without disclosure requirements.

In Somerset, two months after the fire, the hydrant problems remain unfixed. Chief Matisz confirmed in mid-August that "as far as I know, [they] are still dry... I haven't seen work done on them." Construction, meanwhile, continues unabated.
