TL;DR · WeSearch summary

This metric is used by the industry to evaluate the energy performance of a data center; 1.0 represents the maximum theoretical efficiency. In its first phase, the Lin-gang facility is designed to achieve a PUE of no more than 1.15, a figure considered state-of-the-art within the industry.Under this same cooling principle, HiCloud opened the world's first commercial underwater data center in 2023 in Hainan, an island located in southern China. However, the Shanghai complex marks a milestone as the first to operate using offshore wind power.Construction of the UDC was completed in mid-October last year.
