Electricity self-sufficiency rate by sub-region of Korea, 2024 Notes: Electricity self-sufficiency rate = (electricity generated within the region/electricity consumed within the region). VRE self-sufficiency rate = (electricity generated by VRE within the region/electricity consumed within the region). Sub-regions = Seoul Metropolitan Area (Seoui-si, Gyeonggi-do, Incheon-si); Jeju (Jeju-do); Chungcheong (Chungcheongnam-do, Chungcheongbuk-do, Sejong-si); Jeolla (Jeollanam-do, Jeollabuk-do, Gwangju-si); Gyeongsang (Gyeongsangbuk-do, Gyeongsangnam-do, Busan, Daegu, and Ulsan); Gangwon (Gangwon-do). Source: IEA Analysis based data from KEPCO (2025). Although it has the lowest electricity self-sufficiency rate, the Seoul Metropolitan Area currently hosts most of the country's data centres. Around 60% of data fleet and has 14% of Korea's data centres. Jeolla has the highest share of renewables but hosts only 8% of existing data centres.
