Alibaba (BABA) 20 GW Data Center Target: Which Chinese Suppliers Get the Orders

On September 22, 2026, TechNode Global reported that Alibaba (BABA) set its first dated compute target at the Yunqi Conference: Alibaba Cloud's global data center capacity is to exceed 20 gigawatts by 2032. That turns a spending figure into a multi-year build list for suppliers of data center shells, power, cooling and backup power.[1]

The same day, Alibaba's chip unit T-Head unveiled the Zhenwu V900 accelerator for AI training and inference, with mass production planned for the first quarter of 2027; the Qwen 4.5 and Qwen 5 models could scale to 5 to 10 trillion parameters.[1] Alibaba Cloud will add Zhenwu M890 super-node services in Zhongwei, Ningxia, in the fourth quarter of 2026.[3] Per TechWire Asia, CEO Eddie Wu acknowledged a supply squeeze, with demand far outpacing supply capabilities.[2]

On its August 20 call, Alibaba said it had spent RMB 190 billion of its three-year RMB 380 billion AI infrastructure plan and had cut hyperscale AI data center delivery to 100 days.[5] On September 2, a report said its Ulanqab data center in Inner Mongolia was fully occupied and expanding.[4]

BABA rose 4.36% on September 18 and 2.21% on September 21, then closed at $116.27 on September 22, up 0.44%.[7] Optical module makers Innolight (300308.SZ) and Eoptolink (300502.SZ) rose 3.40% and 4.87% on September 18 and fell 1.41% and 0.38% on September 22.[7]

Why a gigawatt target is a physical commitment

Data center capacity is measured in electrical power. One gigawatt is one million kilowatts: the electricity a set of facilities can continuously feed to servers. A target in power rather than money commits the company to a specific amount of construction. For comparison, Microsoft said on September 10 it plans to raise its capacity to 38 gigawatts.[6]

Before any chip goes in, an AI data center needs four things. A shell: a purpose-built facility and racks. A power system converting grid AC into the DC servers use; Alibaba's design, the "Panama" power supply, uses high-voltage direct current (HVDC). Cooling: AI servers run hot and need liquid cooling delivered to the chips. Backup power: diesel generator sets sized to cover full load.

In China these four layers come mostly from domestic vendors. With supply tight and a 100-day delivery cycle, the direct path is to keep the suppliers already building for Alibaba rather than re-tender.

From a gigawatt target to four supplier groups

On the case material's estimate, reaching 20 gigawatts by 2032 from a low-single-digit base implies roughly 2 to 3 gigawatts of new capacity a year.[1][5] Each gigawatt needs matching shell space, HVDC modules, liquid cooling and about one gigawatt of generator sets.

Chip, optical and server names have already risen sharply; Innolight is up 113.6% over one year at about 21 times sales.[7] The shell, power, cooling and backup layer is far smaller: the four companies below reported 2025 revenue of RMB 1.7 billion to RMB 6.1 billion, so the same gigawatt of orders is a larger share of their revenue.[10]

Companies that may be affected

Data Port (603881.SH) builds and operates custom data centers for Alibaba; over 90% of revenue comes from its largest customer, 98% in 2024.[8] It has a RMB 16 billion agreement with Alibaba to 2030 covering expansion of existing sites and new AI compute.[9] IT load is 371.1 megawatts; 2025 revenue was RMB 1.72 billion and capital expenditure rose from RMB 256 million to RMB 777 million.[8][10] If new shells keep going to Data Port, IDC service revenue and IT load may benefit; it depends on how much capacity Alibaba places in domestic custom builds. The stock rose 2.03% on September 22 and is down 36.4% over one year.[7]

Zhongheng Electric (002364.SZ) supplies HVDC power. Per an April 2025 Sina Tech report, it supplies over 90% of the Panama power units in Alibaba's AI data centers under a 2021 framework contract of about RMB 800 million.[11] Data center power is 34% of revenue; 2025 revenue was RMB 2.14 billion.[10] Segment revenue and orders may benefit, unless Alibaba introduces other power designs. The stock rose 1.53% on September 22.[7]

Envicool (002837.SZ) makes computer-room temperature control and liquid cooling; customers include Tencent, Alibaba, Baidu and ByteDance, that business is about half of revenue, and 2025 revenue was RMB 6.07 billion.[14][10] AI liquid cooling may show up in the segment's domestic orders. The stock fell 1.66% on September 21 and 1.14% on September 22 and is down 42.4% year to date.[7]

Cooltech Power (300153.SZ) makes diesel generator sets, 92% of revenue, and is reported to hold 15% of data center backup power at ByteDance, Tencent and Alibaba.[12][10] Late-2024 reports said data center gensets were sold out with prices rising.[13] 2025 net income was RMB 50.94 million, a thin margin.[10] The stock rose 6.43% on September 18 and fell 3.00% and 1.74% on September 21 and 22.[7]

How to verify

Alibaba's mid-November call: whether cumulative spending under the RMB 380 billion plan is clearly above RMB 190 billion, and whether capacity is disclosed in gigawatts.[5] Then whether the Zhongwei super-node goes live in the fourth quarter and the V900 reaches mass production in the first quarter of 2027.[3][1]

Supplier 2026 annual reports, due April 2027: whether Data Port's IT load exceeds 371 megawatts and capex stays at or above RMB 777 million; whether Zhongheng's data center power segment and Cooltech's genset revenue and contract liabilities accelerate; whether Envicool's domestic orders recover.[8][10]

The chain weakens if Alibaba routes new capacity to overseas sites such as Brazil, France or Ireland or leases third-party facilities; if the next capex disclosure shows the RMB 380 billion plan stretched rather than raised; if Zhongheng loses power share; or if genset prices fall back.
