National Energy Administration: The World¡¯s Largest Clean Coal Power Supply System Completed
The National Energy Administration announced today that through over 4 years of ultra-low emission and energy-saving renovation, China now has more than 750 million kilowatts of coal-fired power units, accounting for about 70% of that of the country. Ultra-low emission has been realized, and the world¡¯s largest clean coal power supply system has been completed in China. The ultra-low emission and energy-saving renovation of coal power is reducing the emission levels of soot, sulfur dioxide and nitrogen oxides by controlling the emission of flue gas from coal-fired units. According to experts, the emission standard for flue gas pollutants in China is lower than that of developed countries, but it becomes the most stringent emission standard in the world. Zhu Fahua, President of China Guodian Environment Protection Research Institute: The emission levels of soot, sulfur dioxide and nitrogen oxides generated by our coal-fired power plants are close to those of gas-fired power plants, which means our emission limits are about 50% lower than those of developed countries, which is quite low actually. Since 2014, the annual emissions of sulfur dioxide, nitrogen oxides and soot in China¡¯s coal-fired power industry have dropped significantly due to our efforts on ultra-low emission and energy-saving renovation, and the consumption of net standard coal for power supply has also shown a significant downward trend. According to China Electricity Council, the emission of sulfur dioxide, nitrogen oxides and soot decreased by 86%, 89% and 85% respectively from 2012 to 2017, when the installed-capacity of coal-fired plants in China increased by 30%. The consumption of net standard coal for power supply of coal units dropped from 325g/kWh to 312g/kWh. About 83 million tons of raw coal was saved in 2017. Zhu Fahua, President of China Guodian Environment Protection Research Institute: The atmospheric environment of China has improved significantly compared to 2013, and the concentration of PM2.5 has dropped by about one-third. The ultra-low emission contributed to the improvement. In the Yangtze River Delta Region, the contribution rate reached 24%, the Pearl River Delta Region, 23%, and the Beijing-Tianjing-Hebei Region, 10%. According to officials of the Power Department of the National Energy Administration, the energy efficiency of coal-fired power plants will continue to be improved and efforts will be made to reduce the emission of atmospheric pollutants.
