South Korea Colocation Market: Seoul Hosts 31 Key Data Centers

The South Korean data center industry is expanding rapidly, with total utilized space expected to reach around 3.76 million sq. ft., growing nearly 15% year-on-year. New entrants such as Empyrion Digital, DCI Data Centers, OneAsia Network, Epoch Digital, and STACK Infrastructure are set to drive additional capacity in the colocation market.

Seoul remains the leading hub, hosting over half of the country’s 54 operational colocation facilities. Key providers, including LG Uplus, Digital Edge DC, LG CNS, KT Cloud, and SK Broadband, are leveraging dense interconnection, campus-scale builds, and carrier-grade networks to attract enterprise tenants.

Supported by strong connectivity, a tech-savvy population, and advanced semiconductor and ICT industries, the market benefits from policies favoring domestic technology adoption, particularly in public sector projects. LG Uplus leads the market with a 22% revenue share, reflecting its robust infrastructure and strategic positioning in Seoul.

 

The AI-Driven Evolution of South Korea Data Centers

South Korea is advancing its AI-driven data center landscape, with operators investing in GPU-optimized, high-density facilities. LG Uplus is developing a Paju data center to host over 100,000 servers, deploying liquid-cooling technology to improve energy efficiency and support heavy AI workloads.

This growth aligns with sovereign cloud initiatives and regulatory-compliant infrastructure. SK Telecom’s Haein Cluster leverages over 1,000 GPUs and in-house AI management tools, enabling scalable, secure domestic AI services.

The country’s ambitions as a global AI hub are evident in large-scale projects like Fir Hills’ 3-GW data center in Jeollanam-do, designed for flexible workloads and regional transformation. Strategic site selection near reliable energy sources ensures resilient, scalable power for GPU-intensive operations, positioning South Korea as a key player in the global AI ecosystem.

 

South Korea Sets Bold 20% Renewable Energy Target by 2030

South Korea is accelerating the development of sustainable data infrastructure, aiming to source 20% of its energy from renewables while driving the growth of green and energy-efficient facilities. The country is encouraging renewable energy adoption and low-carbon operations, positioning its data center industry as a regional leader in sustainability. Leading operators, such as Samsung C&T with its hydrogen-powered data center project, are integrating eco-friendly practices to reduce environmental impact and support a low-carbon digital ecosystem.

These initiatives reflect South Korea’s commitment to fostering a resilient, future-ready data center market that aligns with global sustainability trends.
