This project is built or running, so every gate counts as passed.
Build odds is ArusGrid's reading of the public record, not a forecast, a rating or advice. It counts the gates this project has passed in public sources. Private progress does not show, a passed gate can be undone, and projects that pass every gate still stop. The method has not yet been tested against outcomes. How it works.
Huailai holds 8 active projects with 1,294 MW of planned IT load between them, and CapitalOnline Huailai Data Centre, Jingbei Cloud Computing R&D Centre (首都在线京北云计算软件研发中心项目-算力中心) has no published figure so it sits outside that ranking. Of those, 2 are operational, 5 are operational and expanding and 1 is under construction. No third party publishes a colocation vacancy rate for Huailai, and ArusGrid does not estimate one.
It is the only CapitalOnline project ArusGrid tracks. It sits on the CapitalOnline Huailai campus. No tenant has been disclosed, which is normal for colocation and says nothing about occupancy.
The build is phased. Phase 1, building 1# is under construction; Phase 2, buildings 2# and 3#, about 40 MW at 40 MW is announced. The dated record runs from under construction on 21 September 2026 to operational on 12 October 2026. The money on record is CN¥787.01m as of September 2026, the announced investment.
