South Korea's Ministry of Climate, Energy and Environment said it aims to raise renewable energy capacity from about 40 gigawatts to more than 100 GW by 2030, to meet rising electricity demand from high-tech industries and growing electrification. The government will build new transmission and distribution lines, and will also deploy energy storage systems (large batteries that hold surplus power for later use) in areas where the grid is congested. Officials say a shortage of grid infrastructure has been a main obstacle to wider use of renewable power, and Climate Minister Kim Sung-whan said the storage plan aims to make full use of existing networks without waiting for new ones.
