KT Cloud Breaks Ground on 50MW AI Data Center in Ansan

What happened

KT Cloud said on Oct. 22 that it is breaking ground on the Ansan AI Data Center, a company-owned 50-megawatt (MW) AI data center in Ansan, Gyeonggi Province. The building will have a gross floor area of approximately 36,878 square meters with two basement levels and nine above-ground floors, a total incoming power capacity of 50MW, and is scheduled for completion in 2029. The project is part of KT Cloud's long-term strategy to secure 1 gigawatt (GW) of AI data center capacity by 2031 and will add capacity for high-heat-generating AI servers following the opening of the Gasan AI Data Center in 2025. The facility will have power and cooling infrastructure for high-density AI servers, with all server rooms designed to support liquid cooling and a high-load structural design to accommodate advanced equipment including Nvidia's next-generation Vera Rubin GPUs. KT Cloud will also introduce a free-cooling system, using natural airflow during spring, autumn and winter when outdoor temperatures are lower to reduce electricity consumption by cooling tower fans and chillers.
