ST Telemedia Global Data Centres (STT GDC), a Singapore-based data center provider backed by KKR and Singtel, opened its first facility in South Korea on June 16, launching a 30-megawatt site in Seoul to capture surging demand for AI and cloud infrastructure.

The new facility, STT Seoul 1, begins full commercial operations this month. It is run by a joint venture between STT GDC, which holds a 60% stake, and South Korea’s Hyosung Heavy Industries, which holds the remaining 40%. Hyosung specializes in power transmission, distribution solutions, and renewable energy.

The launch marks a strategic push into Northeast Asia for STT GDC, which is expanding a global footprint that includes operations in Singapore, Malaysia, Indonesia, Japan, India, and the United Kingdom.

The Seoul opening comes less than a week after the company announced plans to expand its Jakarta operations to meet rising regional digital and cloud demand.

Covering about 40,000 square meters of gross floor area in Seoul’s Geumcheon district, the facility targets hyperscale and enterprise clients scaling high-density AI workloads.

STT Seoul 1 is aimed at clients with strict efficiency and reliability mandates. It features a design power usage effectiveness of below 1.3 and is equipped with dual 22.9 kilovolt power feeds. It also has backup generators capable of operating for up to 24 hours without refueling.

“AI infrastructure demand is increasingly concentrating in markets where digital capability, power availability, and customer requirements come together,” said Charles Chulhoy Huh, STT GDC’s country head for South Korea.

“STT Seoul 1 establishes an important foundation for STT GDC’s presence in [South] Korea, extending a globally consistent platform into a key Northeast Asian market.”
