South Korea is preparing for a sharp rise in electricity demand driven by artificial intelligence and related semiconductor production. According to reporting that cites government estimates, the country expects AI and chip-fabrication activity to add roughly 25 to 30 gigawatts of additional power demand.
In response, South Korea is considering whether its long-term energy roadmap should include building new nuclear reactors. One outlet frames the projected demand in reactor terms, suggesting the added electricity needs could be equivalent to around 20 nuclear plants based on South Korea’s own reactor output benchmarks. The decision the government faces is how to supply that growth over the longer term—particularly whether to scale nuclear generation to match the expected increase.
Across the coverage, the main emphasis is on the magnitude of the demand forecast and the resulting policy choice. While outlets differ in how they describe the figures (gigawatts vs. number of reactors), they converge on the same basic point: AI-related industrial growth is set to increase electricity needs substantially, and nuclear expansion is being considered as a potential solution.
