The 3.2 billion USD Lake Mariner data center in Somerset, New York, faces scrutiny over accountability and transparency. TeraWulf owns and operates the facility, while Fluidstack manages operations. Google holds warrants for a 14 percent equity stake and guarantees lease payments, and Anthropic relies on the site for compute capacity.
Local officials and residents have raised concerns regarding safety and employment. Following a fire at the site, the local fire department reported difficulties due to missing safety documentation. Although TeraWulf claims to have implemented safety measures, local responders report that some systems, such as hydrants, remain non-functional.
The project has also faced criticism regarding job creation. A 2024 planning board presentation indicated the facility would employ 35 to 40 people, significantly fewer than the 165 permanent jobs promised in 2019. The site is designed to draw up to 500 megawatts of power, which experts note can increase electricity costs for the broader grid.
Environmental claims regarding the facility's energy source have shifted in recent disclosures. While earlier reports cited 95 percent zero-carbon energy, more recent documents refer to a mix of low and zero-carbon sources. TeraWulf acknowledges that it does not purchase renewable energy certificates, as grid electricity is a fungible resource.
Anthropic has committed to covering electricity price increases for consumers related to its data centers, including Lake Mariner. However, the company lacks mechanisms to verify whether TeraWulf or Fluidstack meet specific clean energy or safety commitments. This contrasts with Anthropic's direct control over wholly owned facilities.
