South Korea plans to expand utility-scale renewable capacity from 37 GW last year to 100 GW in 2030, 163 GW in 2035 and 220 GW in 2040, with self-consumption solar lifting the total to 236 GW. Solar is projected to reach 155 GW, offshore wind 45 GW and onshore wind 16 GW by 2040. The plan includes streamlined permitting, expanded transmission and energy storage systems, government-led offshore wind zones and annual offshore deployment of about 4 GW from 2036. Even using estimated solar and wind generation of 364 terawatt-hours, renewables would cover only slightly more than 40% of projected 2040 electricity demand of 847.3–885.1 TWh, leaving debate over nuclear and liquefied natural gas generation. The targets extend earlier goals of 100 GW of renewable capacity by 2030 and a renewable generation share of at least 30% by 2035.
