Google Columbus
Running (some may still be expanding)
Google Columbus is an AI data center in Columbus, Ohio, developed or operated by Google for Google DeepMind. Satellite imagery shows its computers drawing about 303 MW today, against 386 MW planned.
U.S. average: 18.2¢ (+3.4%).
Statewide context, not this project’s effect: prices move for many reasons. Source: U.S. Energy Information Administration.
Satellite figures are Epoch AI estimates from imagery of buildings, cooling and power equipment; about 80% fall within a factor of 1.4 of the true value.
- Jul 1, 2027ScheduledSatellite analysis by Epoch AI · 386 MW planned
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.
- Aug 5, 2026Satellite analysis by Epoch AI · 303 MW in use
Confirmation that Building 4 is complete. Building 5 has progressed since February, with a complete roof, all backup generators in place, and five cooling towers in place.
- May 1, 2026Satellite analysis by Epoch AI · 303 MW in use
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.
- Feb 21, 2026Satellite analysis by Epoch AI · 216 MW in use
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 3 operational. Surrounding roads finished, no more visible construction.
- Mar 1, 2025Satellite analysis by Epoch AI · 130 MW in use
Building 2 operational. Parking complete, no more visible construction.
- Apr 1, 2024Satellite analysis by Epoch AI · 65 MW in use
Building 1 operational. No visible construction and roads/parking complete around the building. Building 2 chillers are beginning construction. Foundation work begins for Building 3.
- Jul 1, 2023Satellite analysis by Epoch AI · 0 MW in use
Building 2 foundation work begins. Building 1 generators seem complete, cooling towers still under construction.
- Oct 1, 2021Satellite analysis by Epoch AI · 0 MW in use
Land clearing begins on the eastern half of the site, for Buildings 1-2
