Record Notes

SK Group and AWS announced a 15-year partnership to build a data center in Ulsan, South Korea for a new AWS AI Zone, with operations expected to begin in 2027. SK Group says it will lead construction while AWS establishes the AI Zone, bringing AI and cloud capabilities to Korean customers. SK Telecom's Korean newsroom later confirmed the August 2025 groundbreaking for SK AI Data Center Ulsan with AWS and Ulsan city participation.

ADCI reduces the selected public capacity from 1,000 MW to 103 MW. Data Center Dynamics reports a phased buildout with 41 MW by November 2027 and 103 MW by February 2029, while describing the 1 GW value as a possible future expansion. The selected value therefore reflects the source-backed early/full disclosed buildout, not the long-term GW-scale roadmap.
