Applied Digital announced on October 2 that the second phase of Building 2 at Polaris Forge 1 had achieved Ready for Service. The phase adds 75 MW of critical IT load across three 25 MW data halls, taking the campus’s operational capacity to 250 MW.
Building 2 now provides its full 150 MW of critical IT load. The company says the leased campus is contracted for 400 MW at full buildout, so the operating milestone covers part of the overall development rather than the entire campus.
For infrastructure owners, the distinction between contracted capacity and commissioned capacity matters. Infraday’s analysis: tracking completed halls and customer handover gives a clearer picture of usable AI infrastructure than a headline campus power allocation alone.
