1 Jan 2022 — Land clearing begins for Building 1 (SIN01)
31 Oct 2024 — Building 1 (SIN01) is completed, but at this point it likely not being used for AI as the collaboration with Microsoft that resulted in GB300s did not occur until Q1 2026. The completion is based both on satellite imagery, which shows the building fully completed, and a March 2025 article that says it "has been in operation since October", which is October of 2024.
3 Apr 2026 40 MW Building 1 (SIN01) operational for AI, with the first deployment of 12,600 Nvidia GB300 NVL72s to the site being reported completed "Q1 2026" based on the corporate announcement. Land clearing also begins for Building 2 (SIN02), with faint dirt outlines for roads and building foundations visible.
16 Aug 2026 40 MW Satellite imagery shows two black outlines, suggesting two buildings going up on a second adjacent site. There is an outline of another building as well. Further to the east, there is land clearing.
30 Sep 2027 · projected 280 MW Building 2 (SIN02) projected to be operational. This is based on the timeline provided in the factsheet for the site. We expect VR200 GPUs to be used as a lot of those chips will have already been available in September 2027, and the "up to 600kW racks" in the factsheet suggest they are aiming for this.
