▷ 11 thermal power plants in the Chungnam, Incheon and Gyeonggi regions to work at 80% capacity  

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).

The upper limit on electro-thermal power generation is based on provisions in the Air Environment Preservation Act and Electric Utility Act and has been implemented on a trial basis since October. It is scheduled to go fully into effect from 2019.

In addition, the government aims to responding to high concentrations of find dust particles that are now occurring by pursuing additional measures such as strengthening environmental protection system operation so that efficiency is maximized.
