Cryptomining company turned data center developer TeraWulf has marked a significant milestone with the construction of its latest facility at the Lake Mariner campus in New York. The company announced that the final structural beam has been placed on their CB4 building, signaling a major step forward in the project.

"Today we topped out CB4, marking the final structural beam placed – all thanks to the crews who brought this build to life", TeraWulf shared in a LinkedIn post. "What stands above is more than steel. It’s execution, coordination, and a shared commitment to delivering critical infrastructure at scale."

The CB4 building, once completed, will provide an impressive 168 megawatts (MW) of capacity, with energization anticipated in the third quarter of 2026. The Lake Mariner campus, set on the site of a former coal plant near Buffalo, is undergoing a transformation from its cryptomining origins to include leasing for artificial intelligence (AI) and high-performance computing (HPC) operations.

Growth at Lake Mariner

Currently, TeraWulf's plans at Lake Mariner include six buildings in total. Of these, three facilities are already live: Wulf Den (2MW), CB1 (16MW), and the first phase of CB2 (42MW). The second phase of CB2, as well as the CB3 (42MW), CB4 (168MW), and CB5 (168MW) buildings, are expected to be fully energized within the year.

The campus currently boasts 500MW of capacity, with plans to expand to 750MW in the future. This shift toward AI and HPC leasing aligns with TeraWulf's broader strategy to diversify its original cryptomining focus.

Strategic Partnerships

TeraWulf has secured notable partnerships to further its goals. Core42, a subsidiary of Abu Dhabi-based technology group G42, is a customer at the Lake Mariner campus. Additionally, AI cloud provider Fluidstack has signed multiple agreements to lease a combined 360MW of critical IT load at the campus in two 10-year deals. These agreements are backed by Google, which has also acquired a 14 percent stake in TeraWulf as part of the partnership.

Beyond New York

TeraWulf's ambitions extend beyond New York. The company is working on additional projects in Texas, Maryland, and Kentucky, with another data center development in New York also on the horizon. By repurposing sites and expanding its footprint, TeraWulf continues to grow its presence in the data center sector, driven by a shift toward supporting AI and HPC operations.

With the topping-out of CB4 and continued development at Lake Mariner, TeraWulf is positioning itself as a key player in the evolving landscape of data center infrastructure. The company’s commitment to execution and collaboration marks a defining chapter in its transition from cryptomining to advanced computing innovation.
