SK Telecom said it will invest 140 trillion won to develop massive AI data centers in the Yeongnam region, unveiling the plan at a public briefing presided over by President Lee. Work will begin on a 100-megawatt hyperscale data center in Ulsan, aimed to start operations by the fourth quarter next year, with plans to add 900 megawatts and 1 gigawatt elsewhere. SKT aims for 5 gigawatts by 2029 and a long-term 15 gigawatt nationwide goal; the initial 5-gigawatt phase would need about 2.5 million square meters, roughly 3 million GPUs, 2.4 million HBM chips and around 350 trillion won in investment.
