China Unicom Southwest Data Center (Chongqing Shuitu) is a data center project in Chongqing, China, operated by China Unicom Chongqing (中国联通重庆分公司). It is operational. The operator has not published an IT load figure. It is planned for 12,800 racks, with 7,687 in service. ArusGrid does not convert racks into MW.
Latest change on record: entered the record as operational in 2014. Record last checked against its sources on 19 October 2026.
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.
Chongqing holds 10 active projects with 0 MW of planned IT load between them, and China Unicom Southwest Data Center (Chongqing Shuitu) has no published figure so it sits outside that ranking. Of those, 6 are operational, 1 is operational and expanding, 2 are under construction and 1 is announced only. No third party publishes a colocation vacancy rate for Chongqing, and ArusGrid does not estimate one.
China Unicom has 9 others in China tracked by ArusGrid, including China Unicom Zhongwei Cloud Data Center, China Unicom (Huailai) Big Data Innovation Industrial Park (中国联通（怀来）大数据创新产业园) and China Unicom Western (Chongqing) Science City Digital Innovation Industry Base. It sits on the Liangjiang Shuitu International Data Port campus alongside China Mobile (Chongqing) Data Center and China Telecom Liangjiang Tenglong Data Center. No tenant has been disclosed, which is normal for colocation and says nothing about occupancy.
The stage was recorded as operational in 2014. Power comes from 中国联合网络通信有限公司重庆市分公司 (substation owner); fed by two 110kV cables from existing 220kV substations through a dedicated substation at 110 kV.
The US export control position for advanced AI chips in China, as of 7 October 2026, is recorded as “Licence required, presumption of denial, case-by-case review for H200-class chips since 15 January 2026”. ArusGrid holds 4 public sources for this project, the latest dated 25 November 2025, and last checked the record on 19 October 2026.
Running capacity. The site is operational or expanding. The rules are fixed and published on the Methodology page.
Cloud pool expected to reach 6 PFLOPS by end 2025, including 4.65 PFLOPS of intelligent computing (Nov 2025).
A party to this project (its operator, that operator's group, a funder, or a confirmed client) is headquartered in China or Macau or has an ultimate parent there. US rules require a licence for advanced AI chips destined to such entities wherever they are located. This describes the rule and says nothing about whether a licence was sought, granted or refused. Criteria are published on the Methodology page.
Licence required, presumption of denial, case-by-case review for H200-class chips since 15 January 2026 · Licence required, presumption of denial, case-by-case review for H200-class chips since 15 January 2026 (2026-10-07) source
No tenant disclosed. Most colocation leases are confidential, so this says nothing about occupancy. Not yet checked against second-order sources.
No published price band exists for China, and ArusGrid does not estimate from the regional benchmark alone. What was searched is listed on the Colo prices page.
