Samsung SDS held a groundbreaking ceremony on Nov. 2, 2026 for an AI data center in Gumi, North Gyeongsang Province, with 60 MW of initial power capacity that can grow to 120 MW in phases, according to The Korea Herald and The Korea Times.

The site covers 46,000 square meters in Gongdan-dong, and completion is targeted for the end of 2028. Construction began after Gumi City approved the project in late August. Samsung SDS approved a 427.3 billion won investment ($319 million, per The Korea Herald) in January and signed an agreement with the provincial and city governments that month.

That makes Gumi the second large Samsung SDS capacity commitment to surface in a week. The company's Oct. 29 earnings call set a target of more than 800 MW of AI capacity by 2031 and a GPU service at Dongtan, in Gyeonggi Province. Gumi is a separate site. At 120 MW, it would be roughly 15% of that 800 MW goal, by Voltgrid's arithmetic, and the first 60 MW would be half of that.

Design and customers

The center combines two cooling methods. Air cooling serves networking and storage equipment, and liquid cooling serves the high-density GPU server areas, according to The Korea Times and Seoul Economic Daily. Samsung SDS says the power infrastructure has redundant equipment and emergency backup supply, and the halls are designed for racks with differing power demands, including ultra-high-power configurations. The sources give no per-rack figure and no GPU count.

Samsung SDS plans to run its own GPU computing services at Gumi and to offer colocation, in which customers install and operate their own GPUs. The Korea Herald said the site will support Samsung affiliates' efforts to deploy AI robots in manufacturing, including compute-heavy training for precision tasks.

The project is the first step in Samsung Group's 60 trillion won ($44.6 billion, per The Korea Times) investment plan, announced in July, for the Yeongnam region, which also covers batteries, packaging substrates and shipbuilding.

Pipeline around it

At its earnings announcement on Oct. 29, Samsung SDS also said it had been picked as preferred bidder for a separate data center project of more than 200 MW developed by Pacific Asset Management, The Korea Herald reported. The company aims to secure 500 MW of data center design, construction and operation projects by 2031. Its third-quarter cloud revenue rose 18 percent year on year to 796.1 billion won.

What is not confirmed yet

Samsung SDS has not disclosed how much of Gumi's planned capacity will go to Samsung affiliates versus outside customers, or when it will expand beyond the first 60 MW, The Korea Herald said. The sources do not state the power source, the grid connection date or the GPU supply for the site, and they do not say whether the 120 MW is critical IT load or total power capacity.
