Google Columbus

Columbus, Ohio, United States

Google Columbus is an operational AI data center in Columbus, OH, USA, with AI chips owned by Google and used by Google DeepMind (likely). It hosts an estimated 215k H100-equivalent chips, scaling toward a projected 321k H100-equivalent chips — supported by 303 MW of IT power, rising to 386 MW — at a capital cost of $11.5 B, rising to $14.6 B. We estimate that it uses Google TPU v5e, Google TPU v5p, Google TPU v6e, and Google TPU v7 chips. The timeline of IT power and compute capacity is based on satellite imagery, our cooling equipment power model, regulatory filings, chip efficiency, and chip availability.

Buildings 1-3 are visibly operational, with steam coming out of the cooling towers. Meanwhile Building 4 is extremely close to completion, with all backup generators complete with only 3 cooling towers missing their fans. ~1/2 the generators are installed for Building 5, and the roof is mostly complete (starting to install the final white layer, with the actual roof structure already complete).

Building 4 operational. No more visible construction, and since only 3 fans needed to be installed since Feburary, operational date was likely soon after. Building 5 roof almost complete.

Building 5 operational. The transmission line construction notice that expands site by 100 MW is assumed to be entirely for Building 5, and has an in-service date of July 1, 2027 (page 3). Estimate taken on the safe side based on completion times for Building 3-4 from when roof was complete.
