Korea's rising energy demand drives nuclear expansion plans

South Korea's government is considering building more nuclear reactors to meet rising electricity demand from AI growth and electric vehicles. Climate Energy Environment Minister Kim Seong-hwan noted AI alone could add 25-30 gigawatts of demand, with additional pressure from transitioning heating systems to electricity. The government plans to extend its long-term energy roadmap to 2040, with nuclear power as a key component. Kim stated 20 new reactors would be needed to meet AI demand, though current reactors are already at 26. South Korea relies on nuclear for just under a third of its power, with coal and gas accounting for 29% and 27% respectively. A survey found 79% of respondents support new nuclear plants. The government aims to increase renewable energy to 11% of total demand, but nuclear remains critical due to limited alternatives. Samsung and SK Hynix, two of the world's largest chipmakers, are expanding production in South Korea, contributing to the energy surge. The government's 800 trillion won 'super project' has accelerated plans, with new factories expected to be completed in the 2030s. U.S. tech firms like Nvidia are also interested in building data centers in South Korea, citing the country's stable power supply. The government plans to phase out 60 coal plants by 2040, with 20 still operational past their design lifespan as potential emergency backups.
