China’s hydropower development will “accelerate†and it is expected to double its installed capacity in the next decade.
At a previous power planning conference, Wang Jianping, general manager of China Electric Power Engineering Consulting Group, stated that in order to realize the promise of 2020, non-fossil energy accounts for about 15% of primary energy consumption, China’s hydropower needs to reach 350 million kilowatts by 2020. Installed capacity.
However, Wang Jianping also pointed out that according to the current progress of hydropower development is not optimistic, the need to increase the efforts of hydropower early work to complete the 350 million kilowatts goal.
Wang Minhao, deputy general manager of China Hydropower Engineering Consulting Group, said that as of the end of 2009, there were 11 hydropower stations approved by the State, which accounted for only 27.1% of the hydropower stations listed in the “Eleventh Five-Year Plan†for renewable energy in China.
Lu Youmei, former general manager of the Three Gorges Development Corporation of the Yangtze River, believes that the issue of interest distribution has hindered the development of China's hydropower and hopes to realize the mechanism of the electricity market as soon as possible and realize homogeneity of the same price.
The “Twelfth Five-Year Plan†According to preliminary planning, China's hydropower development target for 2015 is 310 million kilowatts (0.3 billion kilowatts for pumped storage power stations) and 380 million kilowatts for 2020 (50 million kilowatts for pumped storage power stations).
It is estimated that by the end of 2010, China’s hydropower installed capacity is only 207 million kilowatts, and since hydropower stations generally have a five-year or so cycle, achieving the 2010 target of 380 million kilowatts will mean “12th Five-Year Planâ€. To achieve the goal of adding 0.73 billion kilowatts of hydropower production, and 70 million kilowatts of start-up targets.
According to informed sources, in order to achieve the goal of 15% of non-fossil energy in primary energy consumption, China will substantially increase its non-fossil energy development planning goals.
The informed sources disclosed that according to statistics from 2009, China’s electricity is mainly composed of thermal power, hydropower, nuclear power, and wind power, and its proportions are 75%, 22%, 1%, and 2% respectively.
Since wind power is affected by natural conditions and its power generation capacity is limited, it is hydropower and nuclear power that can effectively increase the proportion of non-fossil energy. However, in early 2010, nuclear power has established a plan for doubling the capacity in 10 years. The nuclear power in various aspects makes the scale " It is impossible to expand. Therefore, the development of hydropower has become the last choice.
“According to consumption, hydropower will achieve 1.3 trillion kilowatts of electricity annually in 2020, and about 600 billion kilowatts in 2010.†According to informed sources, according to the conversion of electricity consumption and installed capacity, non-fossil energy accounts for a primary energy source. With a consumption target of 15%, the hydropower installed capacity in 2020 must reach 350 million kilowatts.
The five-year lost Wang Jianping said that during the “12th Five-Year Plan†period, about 100 million kilowatts should be started, so that the installed capacity of hydropower will reach 350 million kilowatts by 2020. According to the current advances in hydropower development, it is not optimistic and needs to increase the efforts of hydropower preparatory work.
According to Wang Minhao, in 2009 China’s hydropower was composed of 14.54 million kilowatts of pumped-storage power stations and 18,220,000 kilowatts of conventional hydropower, including 55.12 million kilowatts of small hydropower. According to preliminary statistics on the progress of hydropower projects currently under construction, it is expected that the scale of conventional hydropower production in China will reach 207 million kilowatts by 2010.
Although China is currently constructing about 56.17 million kilowatts of hydropower projects, about 50 million kilowatts will be put into operation before 2015, when China's hydropower will reach 246 million kilowatts, through efforts to achieve the "Eleventh Five-Year Plan" goals. However, Wang Min-ho said that China's renewable energy “Eleventh Five-Year Plan†listed 33 key hydropower stations with an installed capacity of 74.021 million kilowatts. As of the end of 2009, there were 11 hydropower stations approved by the State with an installed capacity of 2003 million kilowatts, and the number of hydropower stations approved for the project accounted for only 33.3% of the total number of listed hydropower stations, and the installed capacity accounted for only 27.1%.
Zhang Boting, deputy secretary-general of the China Association of Hydroelectric Engineering, once told the media that since 2007, the state has not actually approved a hydropower project.
In 2009, two projects developed by Huaneng and Huadian in the Jinsha River were halted due to procedural mistakes such as "not approved before construction." This was almost unthinkable two years ago, because almost every hydropower station was constructed side by side.
The lagging development of hydropower in the “Eleventh Five-Year Plan†is worrying. As China’s dominant energy, water power is a risk of being wasted. Wang Minhao stated that China’s total hydraulic power resources ranks first in the world, and its theoretical reserves are 674 million kilowatts, and the amount of technological development can be exploited. It is 542 million kilowatts and the economically exploitable amount is 402 million kilowatts.
The electricity price mechanism to be solved Environmental protection, immigration and other issues plagued the development of China's hydropower, and the “Eleventh Five-Year Plan†almost became the “five-year†that China’s hydropower lost.
The Longkou hydropower station built by the Ludila Hydropower Station and Huanenglong Open Hydroelectric Co., Ltd. built by Yunnan Huadian Ludi Hydropower Co., Ltd. is a typical case of hydropower environmental protection issues.
In June 2009, the Ministry of Environmental Protection approved the closure of the above two projects without the EIA approval in January 2009. This caused a serious ecological impact on the middle reaches of the Jinsha River. It requires the suspension of the construction of the two projects and further requires the suspension of approval before completion of the above-mentioned work. Middle reaches of the Jinsha River Hydropower Development and Construction Project.
According to Lu Youmei, the environmental protection requirements for hydropower are too harsh. Compared to other energy sources, the same energy and hydropower pay the least, and if hydropower is not developed, it may require replacement of thermal power, which may have a greater impact on the environment.
On the issue of immigration, Lu Youmei believes that by helping immigrants get rid of poverty, they can convert mandatory immigration into self-conscious immigration. “Ecological and environmental issues and immigration issues are essentially issues of interest distribution.â€
Lu Youmei believes that there are problems in the calculation of the cost of hydropower development in the western region. “There is no problem that needs to be solved by the western people, which is fully reflected in the unreasonable price of electricity.â€
China's hydropower is determined according to the cost pricing, that is, the hydropower station is reviewed and determined by the Development and Reform Commission's Price Division to determine the on-grid tariff so as to ensure that the hydropower station obtains a reasonable profit. Since hydropower is a free natural resource, its on-grid tariff is generally lower than the average thermal power on-grid price.
“Why is the electricity price of hydropower different from other electricity prices?†Lu Youmei believes that due to the low on-grid tariffs of hydropower stations, it is impossible to fully compensate for the follow-up problems of hydropower construction. For example, if the Three Gorges Hydropower Station can properly increase the on-grid tariff, the Three Gorges can be solved. All remaining issues of the reservoir.
