The underwater data center powered by offshore wind energy in China, said to be the first of its kind in the world, has fully entered commercial operation off the coast of Shanghai’s Lingang Special Zone, according to interestingengineering.
The $226 million project was officially launched in June 2025 through a cooperation agreement signed between the administrative committee of the Lingang Special Zone, the Lingang Special Zone Investment Group from Shanghai, and HiCloud Technology.
Separately, HiCloud has also signed operational agreements with partners, including Shenergy Group, Shanghai Telecom, CCCC Third Harbor Engineering, and others. China Telecom has implemented GPU clusters within the facility as a computing client.
After the completion of the construction in October 2025, full-scale operations began last week, following the initial tests at the beginning of this year.
