Power over time

Every milestone
  1. 8 Oct 2023 — Land clearing begins simultaneously for all three campuses (west, north, and south) after an official ceremony. Two of the campuses later have the cooling capacity indicative of AI workloads, while the other (the north campus) does not.
  2. 24 Feb 2025 — On the west zone, building 1 is structurally complete, and building 4 is structurally complete apart from some remaining cooling towers. Buildings 2 and 5 have begun construction.
  3. 1 Apr 2025 — Four buildings are seen to be structurally complete via satellite imagery.
  4. 1 Jun 2025 42 MW On the west zone, building 1 is operational, assuming a 3 month fit out post structural completion, as can be seen via satellite imagery.
  5. 1 Jul 2025 85 MW On the east zone, building 4 is operational, assuming a 3 month fit out post structural completion, as can be seen via satellite imagery.
  6. 1 Feb 2026 131 MW On the west zone, building 2 is operational assuming a 3 month fit out post structural completion, as can be seen via satellite imagery.
  7. 5 Mar 2026 131 MW Three of the six buildings planned across the three campuses (what can be called phase 1) are operational. One other is near completion, apart from backup generators. The third campus does not have cooling sufficient for AI.
  8. 12 May 2026 131 MW Satellite imagery shows buildings 4 and 5 on the east zone are structurally complete, with landscaping complete.
  9. 7 Jun 2026 131 MW Satellite imagery shows buildings 1 and 2 on the west zone are structurally complete, with landscaping complete.
  10. 1 Jul 2026 212 MW On the east zone, building 5 is operational, assuming a 3 month fit out post structural completion, as can be seen via satellite imagery.
  11. 18 Aug 2026 212 MW On the east zone, building 6 is under construction, and potentially larger than any of the identically sized buildings constructed thus far. Building 3 has not begun construction.
  12. 14 Feb 2028 · projected 415 MW Building 6 is operational (estimate). This was the only new building under construction as of August 2026. Buildings in the previous phases each took 1.6 to 2.3 years from laying the foundations to becoming operational. The new building has a similar shape to a new building at the Huawei Wuhu campus which, based on its cooling and backup power capacity, is about 3.7x the power of previous buildings (see calculations sheet). We expect the chips to be 910C, or to have about the same energy efficiency as the 910C.

Coal made 54% of the power in China
