In the first half of the year, hydropower generation continued to decline year-on-year. China Electric Power Union: insufficient water storage and insufficient precipitation year-on-year | News | Power generation
On July 25th, Pengpai News learned from the press conference of the "Analysis and Prediction Report on the National Electricity Supply and Demand Situation in the First Half of 2023" held by the China Electric Power Enterprise Federation that in the first half of the year, hydropower generation decreased by 22.9% year-on-year, and coal-fired power generation accounted for 60% of the total electricity generation in the whole caliber, fully playing a role in ensuring supply as a backup.
According to Hao Yingjie, Secretary General of the China Electricity Council, in the first half of the year, the power generation of power plants above designated size in China reached 4.17 trillion kilowatt hours, a year-on-year increase of 3.8%. Among them, the hydropower generation of power plants above designated size decreased by 22.9% year-on-year, mainly due to insufficient reservoir water storage and continuous low precipitation since the beginning of this year. Coupled with factors such as a high base in the same period last year, the hydropower generation has continued to decline year-on-year, and the decline has expanded. The hydropower generation in May and June decreased by 32.9% and 33.9% year-on-year, respectively.
In the first half of the year, the power generation of thermal and nuclear power plants above designated size increased by 7.5% and 6.5% year-on-year, respectively. The total grid connected wind power generation increased by 21.2% year-on-year. Coal fired power generation accounts for 58.5% of the total electricity generation in China. Coal fired power remains the main source of electricity supply in China, effectively compensating for the significant decrease in hydropower output and fully playing a role in ensuring supply.
