The Ministry of Trade, Industry and Energy (Minister Sung Yun-mo) and Ministry of Environment (Minister Kim Eunkyung) have announced the first-ever imposition of an upper limit on thermal-electric power generation in three regions―Chungnam, Incheon and Gyeonggi―from tomorrow, in response to the generation of high fine dust concentrations on successive days.
An ultrafine dust alert was issued one day, and the concentration of ultrafine dust was forecast to surpass 50㎍/m3 on the following day, prompting the imposition of the upper limit on thermal-electric power generation.
The power producer selected the power plant units to be affected after considering the electricity supply on the power exchange, grid stability, and the effect on fine dust reduction.
This upper limit on power output will be 80% of the rated capacity of 11 thermo-electric units (5 in Chungnam, 4 in Gyeonggi, and 2 in Incheon) and will remain in effect from 6:00 tomorrow morning until 7:00 PM
As a result, total output will be lowered by 1,100 megawatts, while the ultrafine dust (PM2.5) emissions are expected to be lowered by about 2.3 tons (3% of the daily volume of emissions from coal-fired power plants).
