TeraWulf Completes Structural Work on 168MW CB4 Data Center at New York Campus
March 20, 2026
TeraWulf, a company that has transitioned from cryptocurrency mining to a diversified data center developer, has reached a significant construction milestone at its strategic Lake Mariner campus in New York. The "topping out" of its latest facility, named CB4, underscores the accelerating demand for large-scale, power-dense computing infrastructure, particularly to support the booming artificial intelligence (AI) and high-performance computing (HPC) sectors.
The company announced this week that the final structural beam has been placed on the CB4 building. "Today we topped out CB4, marking the final structural beam placed - all thanks to the crews who brought this build to life," TeraWulf stated. "What stands above is more than steel. It’s execution, coordination, and a shared commitment to delivering critical infrastructure at scale." The new facility is slated to provide 168 megawatts (MW) of capacity once it is energized, which is targeted for the third quarter of 2026.
The Lake Mariner campus, built on the site of a former coal plant near Buffalo, represents a key asset in TeraWulf's portfolio repurposed for the needs of modern enterprise and AI clients. The site currently operates with 500MW of capacity and has the potential for expansion up to 750MW. Of the six buildings planned for the campus, three are already operational: Wulf Den (2MW), CB1 (16MW), and the first phase of CB2 (42MW). The second phase of CB2, along with CB3 (42MW), the newly topped-out CB4, and CB5 (168MW), are all expected to come online within this year.
TeraWulf's strategic pivot is gaining substantial traction, evidenced by major customer commitments. Core42, a subsidiary of Abu Dhabi's G42 technology group, is already a tenant. Furthermore, the company has secured significant, long-term agreements with AI cloud provider Fluidstack, which are backed by Google. Under two separate 10-year deals, Fluidstack plans to lease 360MW of critical IT load from the Lake Mariner campus. As part of these agreements, Google has also acquired a 14 percent equity stake in TeraWulf, signaling strong confidence in the developer's strategy and assets.
The completion of CB4's structural phase highlights the intense pace of development required to meet the unprecedented power requirements of AI workloads. TeraWulf's expansion is not limited to New York; the company is actively developing additional data center sites in Texas, Maryland, and Kentucky, with plans for a second project in New York state. This growth positions TeraWulf as a notable player in the race to build the next generation of high-capacity data centers across North America.
