IT power capacity in operation at the end of each quarter in the large AI data centres tracked by Epoch AI (satellite imagery, permits, filings), in gigawatts. Not a global total: Epoch estimates its hub covers about 43 % of the world's deployed AI compute today, and less in earlier years, so part of the growth reflects wider coverage. Planned capacity is not shown.· Coverage ~43 % today, lower before: growth partly from coverage
