Envision is developing the Galaxy data center campus in Ulanqab, Inner Mongolia, designed to reach 800MW of IT capacity by the end of 2027. The project is being built in four phases for two unnamed internet companies.
To secure power, Envision is constructing dedicated wind farms and battery storage systems. The wind farms, located 80 kilometers away, have a combined capacity of 420MW, intended to supply over 60% of the electricity for the first two phases.
The facility utilizes solid-state transformers to convert 10kV AC power directly into 800V DC for server racks, bypassing traditional intermediate conversion stages. This design reduces the need for conventional components like rectifiers and uninterruptible power supplies.
The campus employs a cooling system where liquid-cooled and air-cooled servers share a single water loop, removing the need for central chiller plants. This approach is part of a broader expansion in the Chahar High-tech Zone, which currently hosts 22 data center projects.
