Perimeter Compute wants to turn spare office power into edge AI data centers

A startup called Perimeter Compute is planning to install AI computer chips inside commercial office buildings, using power capacity that offices no longer need. Buildings built years ago were sized for higher energy use than they now draw, thanks to conservation efforts that cut consumption 30% to 60% over time. Perimeter, led by CEO David Hall, wants to fill that gap by putting chips in basements and mechanical rooms of large office buildings with between half a megawatt and 20 megawatts of spare power capacity, then selling that computing power to AI companies for tasks like running chatbots.

This is mainly a commercial real estate and tech infrastructure story, not something that touches most houses directly. It follows similar moves by home energy companies Span and Sunrun, which have tested using spare capacity from home batteries for small-scale computing. Perimeter's approach is aimed at office landlords, not homeowners: building owners would not pay for any of the equipment, installation, or extra energy use. Perimeter covers those costs and pays landlords a share of the revenue and rent for the space.

The bigger question raised is what this could mean for local power grids. Perimeter is already talking with utilities in cities like New York and Boston, since some local grids are already tightly stretched. Unlike offices, which draw power unevenly, the chips would need electricity around the clock, which could strain grids that utilities have already stretched thin across many customers. For now, no contracts are signed, and it is unclear how widely this model will spread.
