Amazon Madison Mega Site
Running (some may still be expanding)
Amazon Madison Mega Site is an AI data center in Canton, Mississippi, developed or operated by Amazon for Anthropic. Satellite imagery shows its computers drawing about 284 MW today, against 683 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.
- Mar 15, 2028ScheduledSatellite analysis by Epoch AI · 683 MW planned
Buildings 8-12 are operational. In June of 2026 only a faint outline of buildings 10,11 and 12 is visible, estimating construction completion to be the end of 2027, alligning with expected completion by 2027. This final estimates adds three months to that for server installation.
- Mar 1, 2027ScheduledSatellite analysis by Epoch AI · 284 MW planned
Buildings 6 and 7 operational, estimated from roofs having been completed 9 months ago (similar timeline to AWS buildings at New Carlisle in 2025).
- Jun 4, 2026Satellite analysis by Epoch AI · 284 MW in use
Buildings 6 and 7 roof completed. Building 8 roof nearly completed. Building 9 roof half way up. No new operational buildings.

Confirmation that five buildings are fully equipped with cooling and backup generators.
- Jun 23, 2025Satellite analysis by Epoch AI · 284 MW in use
Buildings 1-5 are operational, based on roofs being completed 5 months ago and generators being installed by 2025-04-10.
- Mar 11, 2025Satellite analysis by Epoch AI · 0 MW in use
Generators and chillers still being installed on buildings 1-5.
