KT Cloud announced on October 22 that it would begin construction of the 50 MW Ansan AI data center, a facility it will own, to expand AI infrastructure supply in the Seoul metropolitan area and address demand for high-density AI servers. The project forms part of KT Cloud's strategy to supply 1 GW of AI data center capacity by 2031 and is intended to expand the supply base for high-density AI infrastructure in the metropolitan area. KT Cloud plans to secure new data centers in stages, including the Ansan facility, to increase its AI infrastructure supply capabilities and strengthen its technological competitiveness in supporting next-generation AI server environments. The Ansan AI data center will be a hyperscale facility dedicated to AI, with approximately 36,878 square meters of gross floor area, 2 basement levels, 9 aboveground floors and a total incoming power capacity of 50 MW. It targets completion in 2029 and incorporates specialized designs across power, cooling and building structure to accommodate the high density and heat output of AI servers. It will have power infrastructure capable of supplying high-density AI servers reliably. All server rooms are designed to accommodate liquid cooling, expanding cooling infrastructure for high-heat-output AI servers following the Gasan AI data center, which opened in 2025. The facility also adopts a structure designed for heavy loads to accommodate high-performance GPUs such as NVIDIA's next-generation Vera Rubin AI GPU, allowing it to respond flexibly to future increases in server density and changes in equipment specifications. A high-efficiency free-cooling system will also be introduced to improve cooling energy efficiency. Cooling coils will be installed on the exterior walls to use natural airflow around the upper part of the building and connected to closed-circuit cooling towers, using low outdoor temperatures for cooling during spring, autumn and winter. This is intended to reduce the operating load on cooling tower fans and chillers and improve the data center's cooling energy efficiency. Kim Bong-gyun, head of KT Cloud, said, “The Ansan AI data center is a project incorporating power and cooling infrastructure optimized for high-density AI servers and next-generation design technologies.” Kim added, “Drawing on our accumulated experience in building and operating data centers and our in-house technological capabilities, we will provide reliable and efficient AI infrastructure and actively address customers' diverse technical requirements.”
