Hyundai E&C Completes Korea's Largest 'Yongin Jukjeon Data Center' in 1.3 Trillion Won Project

64MW IT Load and 100MW Power Receiving Capacity Secured
Simultaneous Underground and Above-Ground Construction on a Limited Urban Site
Eco-Friendly Data Center with Enhanced Energy Efficiency

Hyundai Engineering & Construction has completed the nation’s largest hyperscale data center, establishing a key hub for responding to the artificial intelligence (AI) industry and expanding digital infrastructure.

On October 24, Hyundai Engineering & Construction announced the completion of the “Yongin Jukjeon Pacific Sunny Data Center” in Yongin, Gyeonggi Province. The project was commissioned by Pacific Asset Management and jointly invested in by the Canada Pension Plan Investment Board (CPPIB) and Shinhan Investment, with a total value of 1.3 trillion won. The site, with a total floor area of 99,125 square meters (approximately 30,000 pyeong), houses two data center buildings and auxiliary facilities.

This data center is a super-large facility in Korea, equipped with a 64 MW IT load (power supplied to IT equipment) and a 100 MW power receiving capacity. This is equivalent to the amount of electricity used by 160,000 to 200,000 households in a single day. To meet the rapidly increasing demand for high-performance computing (HPC) in industries such as cloud and internet services, the center was designed for high-density operation exceeding 10 kW. It adopts a “neutral” network structure that is not dependent on any specific telecommunications provider, creating an open infrastructure that can accommodate the traffic needs of various global operators. Its proximity to the Pangyo area positions it as a key hub in the southern metropolitan digital corridor.

The project, which began construction in February 2022 and was completed in about 43 months despite the limited urban site, showcased Hyundai Engineering & Construction’s unique project management expertise. The STD (Strut-Top-Down) method was applied to carry out underground excavation and above-ground structural work simultaneously. In addition, BIM-based design minimized interference, and the fast-track method enabled precise integration and management of complex equipment, power, and piping processes. This approach ensured both quality and safety while shortening the construction period.

The center also boasts industry-leading energy efficiency and operational stability. With a high-efficiency cooling system, pre-cooling, and real-time energy monitoring, it achieved a Power Usage Effectiveness (PUE) of 1.3. This meets global cloud company standards and is recognized as an eco-friendly solution that minimizes power loss and reduces carbon emissions.

The facility has also secured stability at or above the international “Tier 3” certification standard. Emergency generators, uninterruptible power supplies (UPS), and chillers are all duplicated or triplicated, establishing a seamless power supply system that ensures uninterrupted operation under any circumstances.

A Hyundai Engineering & Construction representative stated, “The completion of the Yongin Jukjeon Data Center is a testament to our capability to build stable and efficient infrastructure as the digital industry advances. We will continue to expand our digital infrastructure network around key metropolitan hubs and develop eco-friendly data center models that meet the needs of the AI and cloud industries.”

Since building the Financial Settlement Center in Bundang in 2004, Hyundai Engineering & Construction has constructed more data centers than any other domestic builder, including KT Mokdong IDC, Naver Data Center “Gak Sejong,” and K-Square Data Center Gasan. It is the only Korean construction company to have built data centers for global big tech firms, demonstrating world-class technology and expertise. Moving forward, Hyundai Engineering & Construction plans to realize both core AI infrastructure and energy innovation by developing eco-friendly, small modular reactor (SMR)-linked data center models tailored to the energy characteristics of each region.
