KT Cloud said it will break ground on its own 50-megawatt Ansan AI data center in the Seoul metropolitan area, with completion targeted for 2029, according to Digital Today's English edition. The company described it as a hyperscale, AI-dedicated facility with a total power receiving capacity of 50 MW.

The building will have a gross floor area of about 36,878 square metres across two basement floors and nine above-ground floors. KT Cloud said it applied specialised designs across power, cooling and building structure to handle high-density, high-heat AI servers. A Korean report found by search says every server room is designed for liquid cooling and a heavy-load structure for next-generation NVIDIA GPUs such as Vera Rubin; that detail is not in the Digital Today text and rests on the Korean report.

Ansan is part of KT Cloud's plan to supply 1 gigawatt of AI data center capacity by 2031. The company said it intends to secure new data centers sequentially, Ansan included. At 50 MW, the site would supply 5% of that target, so the remaining 950 MW still needs sites, power connections and equipment.
