Zhejiang's data centers are clustered around Hangzhou, the home of Alibaba, and are run mostly by China's state telecom companies and big cloud firms. China Mobile's Zhejiang arm is building its Yangtze River Delta (Jiashan) computing center in Jiaxing as a national hub, and in 2026 aims to push its AI computing centers in the province past 500 megawatts of power, China National Radio reported in March. It is also expanding centers in Hangzhou, Ningbo and Jinhua.
Electricity is the local problem. Hangzhou's data centers used 4.27 billion kilowatt-hours in 2025, the most of any city in the province, and could use nearly a fifth of the city's power by 2030, the energy outlet Ditan reported in April. Hangzhou has almost no coal, gas or oil of its own, and its grid runs near its limit in summer heat. The city now fixes each new computing project's power demand, substation and grid connection when the land is acquired.

Most of the extra power comes from outside: hydropower from Sichuan and wind and solar from the northwest, sent over long-distance high-voltage lines. Green power used by Hangzhou's computing industry rose ninefold in three years. During six days of the 2026 Spring Festival, China Telecom's Hangzhou big data center took in 368,700 kilowatt-hours of surplus green power while factories were idle.
The oldest landmark is Alibaba Cloud's Qiandao Lake data center in Chun'an County, opened in 2015. It pipes water at 63 degrees Fahrenheit from 115 feet below the lake's surface to cool its servers, which Alibaba said gives it free cooling 90 percent of the year.
