Will it get built?Built7 of 7 gates passed
✓ Land secured✓ Power arranged✓ Approvals granted✓ Money committed✓ Tenant or own use✓ Builder appointed✓ Construction started
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.
China, 2026-10-12. China coverage is a pilot of one cluster, Zhongwei in Ningxia, entered on 12 October 2026 from Chinese-language primary and state press sources. Other Chinese hubs are not yet covered, so no China total here describes the country. Many Chinese projects publish rack counts and no megawatts. ArusGrid records the rack count and leaves capacity blank rather than convert it.
Where it sits
Huailai holds 8 active projects with 1,294 MW of planned IT load between them, and Hoyinn Data (Huailai) Technology Industrial Park (合盈数据（怀来）科技产业园) ranks first by planned capacity. 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 Hoyinn project ArusGrid tracks. It sits on the Hoyinn Data Huailai Technology Industrial Park, Huailai County. No tenant has been disclosed, which is normal for colocation and says nothing about occupancy.
The dated record runs from under construction on 1 November 2022 to operational on 1 December 2025. The money on record is CN¥18bn as of August 2026, the published figure. Power comes from self-built through a dedicated substation (reported, unconfirmed). Cooling uses hybrid air and liquid cooling.
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 6 public sources for this project, the latest dated 13 September 2026, and last checked the record on 19 October 2026.

Access to AI chips
GradeLicence required for a party
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.
US licence required for this destination as enforcedYes
A party headquartered in China or Macau on the projectYes
Country-level export frameworkNo

Power allocation or plan北京中科合盈数据科技有限公司 (own renewable plants) · Aug 2026 Reported source ↗ Hoyinn has built several renewable plants in Weixian, Guyuan and Zhangbei (Zhangjiakou) with 2.78 GW installed and grid-connected. Their full output could cover a year of the park's use. More than half of park power is green and some projects run on 100 percent green power. · The park is described as the largest source-grid-load-storage carbon-neutral demonstration around Beijing. Power is dispatched by the Jibei grid, and the data centres draw on energy storage when renewable output drops. 2.78 GW is generation capacity, not grid supply to the park. · Applies to the whole campus.
