SK Chairman to Inspect Ulsan AI Data Center Under Construction With AWS

SK Group Chairman Chey Tae-won is scheduled to visit the SK AI Data Center Ulsan construction site on September 10, highlighting the group’s focus on a project it is developing in collaboration with Amazon Web Services.

The facility remains under construction. SK has stated total project investment of KRW 7 trillion and plans to bring the data center into operation by the end of 2027. The company describes it as the largest dedicated AI infrastructure project outside South Korea’s capital region.

The visit is expected to cover construction progress at the Ulsan site, as well as the deployment of AI technologies at SK Innovation’s Ulsan CLX industrial complex. SK has identified the Ulsan facility as the first flagship project in its broader 15 GW-class AI-infrastructure plan for South Korea. That 15 GW figure applies to the wider national plan, not to the Ulsan data center itself.

SK also plans to develop the Yeongnam region, beginning with Ulsan, into an AI data-center cluster exceeding 2 GW in aggregate. This figure refers to a future regional cluster rather than current capacity at the Ulsan facility, and the source does not specify whether the GW figures represent IT load, power capacity or another measurement basis.

For infrastructure markets, the project could signal intensifying competition for AI compute infrastructure outside the Seoul metropolitan area. If the cluster plans proceed, they could drive regional demand for power interconnections, data-center development, network infrastructure and cooling systems. These capacity figures and timelines remain plans rather than confirmed operating capacity.
