Originally announced in 2020 as a US$315 million joint venture between Actis and GS Group, the Actis–GS Seoul internet data centre project has since evolved into part of Actis’ broader Epoch Digital platform strategy across Asia. As of 2026, the development is no longer a standalone 21MW facility, but part of a multi-site hyperscale portfolio in Greater Seoul. It also includes operational assets and new builds such as a 26MW facility nearing service in 2026 and additional pipeline capacity exceeding 65MW.

The growth of Actis–GS Seoul data centre project also reflects the continued increase in hyperscale demand in South Korea. Increase in hyperscale demand in South Korea is also increasing the need for more renewables supply especially for energy intensive data centres. An example of this is Navea’s PPA with GS E&R from a Yeongyang wind farm currently under construction in North Gyeongsang Province.

Actis and GS Group to Construct US $315M Internet Data Centre in Seoul, South Korea

Reported September 30, 2020 – Actis and GS Group are set to build and operate a US $315m internet data centre (IDC) in Seoul, South Korea; one of Korea’s largest conglomerates. The 21MW IDC will be capable of hosting top tier cloud service providers (CSPs) allowing them to address a significant mismatch between supply and demand in Seoul. The city also has 95% smartphone penetration, and is one of the highest in the world. It has also seen mobile data traffic increase by 26 times since 2012.

The new eight-storey facility is GS E&C’s tenth data centre project. It will be built to Tier 3 standards, feature 1,600 high density racks for CSP clients, and a further 400 low density racks for co-location customers. The IDC will be located within the Pyeongchon Cluster, which boasts the highest concentration of CSPs in Seoul.

The investment is also a continuation of Actis’ build-to-core strategy in Korea and expands its experience in the fast-growing digital infrastructure segment. The firm has created a Chinese data centre platform, Chayora Holdings, to develop hyperscale data centre facilities to serve China’s tier 1 markets. In early 2020, Actis also established a $250m pan-African data centre platform, starting with an investment in Rack Centre in Lagos, Nigeria.

According to Brian Chinappi, Head of Asia real estate at Actis, Seoul has an insatiable appetite for data but is struggling to meet demand with fewer than five largescale non-owner occupied data centers currently available in the market. “This investment, where land and grid power have been secured, in an area popular with CSPs, will directly help to address that challenge. We are also pleased to be working with GS E&C, an experienced local contractor that has built 185MW of existing IDC capacity. Together, this project will deliver another critical piece of digital infrastructure for Korea,” he said.
