KT Cloud, the cloud and data center arm of South Korea's KT, will design, build and operate a 50-megawatt AI data center in the Cheongna district of Incheon, west of Seoul, Seoul Economic Daily reported Wednesday. Construction is due to start in the fourth quarter of this year, with completion targeted for the first quarter of 2030.

What Happened

KT Cloud is taking part as a design, build and operate partner, according to the report. That role covers design consulting, management of mechanical, electrical and plumbing work, commissioning to verify stability and operations, and running the facility once it opens. Hyundai Engineering, the joint contractor, will carry out architectural, civil, equipment, landscaping and telecommunications work as well as the mechanical, electrical and plumbing construction.

The building will have two basement levels and 11 floors above ground. Inside, it will use hybrid data halls: an "AI zone" with direct-to-chip liquid cooling for high-density GPU servers, and a separate "cloud zone" for general-purpose cloud services.

The report did not give an investment figure, the number of GPUs planned or details of the site's power supply, and it did not name an owner or developer beyond KT Cloud and Hyundai Engineering.

Why It Matters

Location is a selling point. Cheongna sits in the western part of the greater Seoul area, within an hour of the capital's main business districts, and KT Cloud plans to connect the new facility with its existing data centers in Gasan and Mok-dong, both in the capital region. Linking the sites is meant to let customers expand across locations and to keep network service running if one site has problems.

The split design reflects how AI hardware has changed data center construction. Racks of current GPU servers draw far more power and produce more heat than conventional cloud servers, and direct-to-chip liquid cooling, which carries heat away from processors through cold plates, is becoming a standard requirement for that equipment. Building separate zones lets one facility serve both dense AI workloads and ordinary cloud tenants.

KT Cloud CEO Kim Bong-kyun said the company expects the site to become a key hub in the western cluster of the capital region and to meet demand from Korean and overseas companies that need large-scale AI infrastructure. He said KT Cloud will keep adding AI data center capacity both inside and outside the capital region.

The Gigawatt Target

Including Cheongna, KT Cloud plans to supply more than 1 gigawatt of AI data center capacity by 2031. At 50 megawatts, the Incheon project is a small fraction of that goal, which implies a steady pipeline of further sites over the next five years. Korean telecom and cloud companies are adding AI-ready capacity as the government promotes domestic AI development and as international firms look for capacity in Asia.

What to Watch

The next milestones are the groundbreaking in the fourth quarter and any announcement of anchor tenants for the AI zone. Also worth watching are disclosure of the project's cost and power arrangements, and further site announcements that show how KT Cloud intends to reach its 1-gigawatt target by 2031.
