CEC Says Unpredictable Hydropower Situation this Winter

The China Electricity Council (hereinafter referred to as “CEC”) recently released “A Brief Analysis of the Operation of the Electric Power Industry from January to October in 2011” (hereinafter referred to as “Analysis”), pointing out that the dry season has come earlier and leading reservoirs in major river basins The value of energy is greatly reduced, and the entire hydropower situation is severe this winter.

"Analysis" said that from January to October, the national hydropower plant above designated size had a capacity of 517.5 billion kWh, which was a year-on-year decrease of 2.2% since 2005, and it was the first time since 2005 that year-on-year negative growth occurred; hydropower generation accounted for 13.6 of the total output of power plants above the national scale. %, 2.9 percentage points lower than the same period of last year.

The main cause of the above situation is that the major rivers in the country have generally had dry and dry water since April. Among them, hydropower generation in the provinces with relatively large hydropower installed capacity in the south, central China, and eastern China is particularly declining.

During the period of statistics, the average utilization hours of hydropower equipment nationwide was 2,639 hours, which was 379 hours lower than the same period of last year. It was the lowest level in the same period since the “Eleventh Five-Year Plan”; among them, hydropower installations in Fujian, Jiangxi, Guangdong, Hunan, Qinghai, Jilin, Zhejiang, Hubei, etc. The utilization hours of hydropower equipment in provinces with larger capacity have fallen by more than 600 hours. Therefore, "Analysis" believes that the situation of hydropower production in winter is not optimistic.

Zhang Boting, the secretary general of the China Society of Hydroelectric Engineering, said that due to the dramatic advance of the dry season in 2011, leading to a significant reduction in the energy storage value of leading reservoirs in major river basins, the entire hydropower situation is severe this winter.

A person in charge of a hydropower plant in the southern part of Hubei Province, Guodian Group, said that the power generation capacity of the hydropower plant where he is located has been the lowest in recent years, only 80 million degrees, and the average power generation in previous years was 110 million kWh.

Although the above-mentioned power plant of the above-mentioned person in charge has two sets of generating units with a installed capacity of 37,000 kilowatts and is a medium-sized power plant, even so, the power plant may soon be “captured” by brothers in the integration of hydropower assets within the group. .
