Energy Bureau: The proportion of installed coal power will gradually decline

According to an authoritative source from the National Energy Administration, it is expected that starting from 2015, the scale of China's newly installed power plant with coal power installed capacity will be lower than the scale of the clean energy installed capacity. By 2020, China's coal power share accounts for less than 70% of total installed capacity; by 2050, it will drop below 50%.

At present, China's coal power installations account for 74% of the total installed capacity. Coal-fired power plants consume about 1.4 billion tons of raw coal each year (accounting for 50% of China's raw coal production).

According to the above sources, the development of high-efficiency and clean coal power generation, the improvement of the thermal efficiency of coal-fired power units and the reduction of pollutant emissions are the inevitable choices for the future development of coal-fired power in China.

The average thermal efficiency of existing coal-fired units in China is about 35.6%, which is lower than the advanced level in developed countries, and the corresponding pollutant emissions are also high. At present, the thermal efficiency of the most advanced ultra-supercritical coal-fired units can reach 45%, and the thermal efficiency of the new-generation ultra-supercritical coal-fired units can reach more than 50%. Judging from the current level of technological development, a new generation of ultra-supercritical coal-fired power generation, supercritical circulating fluidized bed power generation, and integrated coal gasification combined cycle power generation will gradually become mainstream.

In terms of ultra-supercritical coal-fired generating units, the above-mentioned sources expect that by 2020, China will fully grasp the design and manufacturing technology of ultra-supercritical 600,000-kilowatt and 1 million-kilowatt-series generator sets, and supercritical and ultra-supercritical generating units will account for this. 30% of the total capacity of thermal power units will account for 50% in 2050.
