The country’s Ministry of Trade, Industry and Energy said Thursday that between eight and 15 generators will close from December 1 to February 29, with the remainder operating at a maximum 80% capacity.
There are 13 coal plants in South Korea, according to the Korea Power Exchange, and there can be multiple generators within one plant
It will be the first time South Korea has closed coal-fired generators during winter — when demand for electricity is at its highest — and the ministry said the move would reduce fine dust emissions by 44% from last year.
PM 2.5 are microscopic particles smaller than 2.5 micrometers in diameter which are considered particularly harmful to humans because they are small enough to lodge deep into the lungs and pass into other organs.
While pollution in South Korea is being driven by factors such as factories, car exhausts and coal heating, many in the country blame emissions blown across the Yellow Sea from China for exacerbating poor air quality.
South Korea has 58 publicly owned coal-fired generators. A total of 46% of the country’s energy is generated from coal, according to the largest electric utility, Korea Electric Power Corporation.
The South Korean government has pledged to move away from coal as public anger over increasingly hazardous levels of pollution grows.
