China has completed the first phase of what it claims is the world's first underwater data center in Shanghai's Lingang Special Area. The facility cost roughly 1.6 billion yuan ($226 million) and operates on twenty-four megawatts of power drawn entirely from wind energy.
Seawater acts as a natural cooling system for the submerged servers. Traditional land-based data centers devote up to 50% of their energy consumption to air conditioning. The underwater design reduces cooling energy demand to less than 10%. The first phase is designed to achieve a power usage effectiveness rating of no more than 1.15. More than 95% of the facility's electricity comes from offshore wind turbines in the East China Sea. The project reduces land usage by more than 90% and eliminates the need for fresh water. The main contractors signed an agreement to launch another offshore wind-powered underwater data center with a capacity of 500 megawatts.
