50 MW facility in Ansan
kt cloud is building a 50 MW dedicated artificial intelligence (AI) data center in Ansan, Gyeonggi Province. It will expand AI data center supply in the Seoul metropolitan area by securing the electricity and cooling infrastructure needed for high-performance graphics processing unit (GPU) servers.
kt cloud announced on October 22 that it is starting construction of its own Ansan AI Data Center. The project is part of its medium- to long-term strategy to secure 1 GW of AI data center supply capacity by 2031.
The Ansan AI Data Center will have a total floor area of approximately 36,878 square meters, with two basement levels and nine above-ground floors. Its total incoming power capacity will be 50 MW, with completion targeted for 2029.
Cooling and structural design
The data center will have electricity and cooling infrastructure needed to operate high-density AI servers. All server rooms will be designed to support liquid cooling. Following the Gasan AI Data Center, which opened in 2025, it will add another facility capable of accommodating AI servers with high heat output.
A high-load structural design will also account for the introduction of high-performance equipment such as NVIDIA's next-generation Vera Rubin GPUs. The building structure has been designed to accommodate future increases in server density and changes in equipment specifications.
A free cooling system will also be introduced to improve cooling efficiency. Cooling coils will be installed on the upper exterior walls of the building and connected to closed-circuit cooling towers. The company plans to use outside air during cooler weather in spring, autumn and winter to reduce electricity consumption by cooling tower fans and chillers.
