Will operate 30MW data center in Seoul.
KT Cloud is set to be the operator of a data center currently under development in Seoul, South Korea.
The company has been confirmed as the operator of the upcoming 30MW Guro Data Center located at 166-2 Gae Bong Dong in Seoul, following a contract change.As reported by Chosun Biz, the data center is being developed by Capstone Asset Management.
KT Cloud won the "design, build, operation" project and will also lease 15 percent of the data center for its own use.
Works on the data center began in February of this year, with an expected completion date of April 2028. The data center will be built on a site spanning 3,354 sqm (36,102 sq ft) and will have four floors below ground, eight above ground. In total, the data center will span a total of 19,225 sqm (206,936 sq ft). Total IT capacity is estimated to be 19.8MW.
KT Cloud will handle the mechanical, electrical, and plumbing work at the data center, while SK Eco Plant will take on construction.
Plans for the data center were first initiated by Lotte Engineering & Construction in 2021, but the principal contractor was switched to Capstone Asset Management in 2024 due to financial difficulties. The total cost of the data center project is estimated to be 130 billion won ($914m), of which Capstone has invested 105 billion won ($738.2m).
KT Cloud was formed as a separate business unit of South Korean telecoms firm KT Corp in 2022. In July 2022, the company announced plans for a 26MW data center in southern Seoul’s Geumcheon District. The facility, Gasan IDC, has 10 stories above ground and five under, with a capacity for more than 100,000 servers. As of 2022, the company had cloud regions in Cheonan and Gimhae in Seoul and a US zone in Los Angeles, California.
Datacenters.com lists 10 KT Cloud data centers across South Korea, though Chosun Biz reports the company had 14 data centers. Plans to establish an AI Data Center Demonstration Center at KT's Mok-dong DC 2 Center in the Yangcheon District of Seoul were revealed in March 2025.
