The South Korea data center market was valued at USD 5.04 billion in 2025 and is projected to reach USD 16.23 billion by 2031, expanding at a robust 21.5% CAGR during the forecast period according to Arizton latest research. The market is scaling rapidly as AI adoption, cloud computing, big data, IoT, and sustainability-driven infrastructure investments accelerate nationwide.
While Seoul remains the primary demand hub, power constraints and government-led decentralization since 2024 are pushing new developments into secondary cities such as Incheon, Busan, Daejeon, and Goyang. At the same time, stricter data sovereignty requirements under the Personal Information Protection Act (PIPA) are reinforcing domestic data center investments.
Hyperscalers including Amazon Web Services, Microsoft, and Tencent are deepening their presence, particularly with AI-ready facilities. Parallelly, renewable PPAs and government-backed energy initiatives, led by the Ministry of Trade, Industry, and Energy, are shaping a more sustainable, future-ready data center ecosystem.

Investment by Area: Industrial Land Trends Across South Korea
Industrial land pricing in South Korea varies sharply by city, reflecting uneven infrastructure density and demand concentration. In 2025, land prices ranged from USD 3,590–12,565 per sq. m in Seoul, compared with USD 1,130–11,600 in Seongnam and USD 1,820–10,380 in Incheon, making peripheral markets increasingly attractive for large-scale data center development. As colocation and hyperscale operators continue to invest aggressively, demand for industrial land is rising, putting sustained upward pressure on prices nationwide. This trend is reinforced by South Korea’s expanding network of free economic zones, offering tax incentives, affordable land leasing, simplified regulations, and strong logistics, which is supporting greenfield data center projects. However, as land costs escalate, the area required per MW is expected to decline over the next three to five years, pushing developers toward more space-efficient, higher-density facility designs.
AI Adoption Scales Across South Korea’s Digital Economy
The adoption of artificial intelligence (AI) in South Korea is accelerating across multiple sectors, supported by the country’s advanced digital infrastructure and strong focus on technological innovation. AI is playing an increasingly critical role in driving digital transformation across industries such as manufacturing, automotive, healthcare, and finance, as enterprises integrate intelligent systems to improve operational efficiency, streamline processes, and enable data-driven innovation. To support this expansion, South Korea is actively strengthening its AI ecosystem through initiatives focused on developing AI-ready data centers, increasing government support, and encouraging AI adoption across key industries to enhance long-term sustainability. As AI workloads generate massive volumes of data, demand for high-performance servers with greater rack density and power efficiency is rising, leading to higher heat output within data centers
Clean Energy Investment Accelerates South Korea’s Power Market Transition
South Korea is advancing a structured energy transition agenda aimed at increasing the share of renewable electricity to 20% by 2030 and around 35% by 2040, while working toward carbon neutrality by 2050. To support these long-term targets, the government announced an investment of approximately USD 89.5 million in energy-sector R&D in February 2025, with early funding directed toward 41 projects focused on renewable energy, nuclear power, hydrogen, and related technologies. This policy-led approach highlights South Korea’s commitment to strengthening green energy production while building a resilient and sustainable power ecosystem.
