Power over time

facility power · 6 milestones

Every milestone

13 Dec 2021 — Building 1 land clearing begins.
3 Mar 2025 — Building 2 roof starts to go on and its cooling installation is in progress.
4 Nov 2025 — We believe Building 1 and 2 are still being finished due to continued construction vehicles and unfinished land around the data center sites.
2 Feb 2026 — Color artifacts appear on small number of Building 1 fans. Continued presence of construction equipment and unfinished land around Building 2 suggests the final phase of construction.
4 Mar 2026 105 MW We estimate that Building 1 is operational 30 days after the appearance of color artifacts on the fans.
2 Jun 2026 198 MW We estimate Building 2 becomes operational due to being 120 days after final phases of construction, 9 months since roof and cooling were done, and similar Meta data centers construction timelines.
