Energy Bureau: Hydropower will develop toward large capacity

China Securities Journal reporter learned from relevant sources of the National Energy Administration that it is expected that by 2020, China will put in more than 100 sets of hydropower generating units with a rated capacity of 700,000 kilowatts and above. China's hydropower development will develop in the direction of large capacity in the future.

It is understood that in recent years, China's hydropower development and construction of hydropower stations have shown a tendency toward large-capacity development. The Xiluodu and Xiangjiaba hydropower stations under construction have a total of 36 units with 700,000 kilowatts and above. At present, China's hydropower installed capacity is about 200 million kilowatts. Nu River and Yarlung Zangbo River have not yet been developed. The overall development of the Jinsha River, Yalong River, Dadu River and Lancang River is less than 10%, and the potential for large-scale hydropower development is huge.

The above persons expect that, with the development of hydropower in Tibet from 2030 to 2050, the operating heads of four million-million-kilowatt hydropower stations will exceed 400 meters and the maximum water head will reach 830 meters. Ultra-high head and super-capacity hydropower will become the development of hydropower in China. The main direction.

In the eyes of experts, the development of large-capacity hydropower stations is also conducive to the realization of local environmental and ecological protection, but the concentrated development of large-capacity hydropower plants will also bring about the problem of large-scale hydropower transmission. Therefore, large-capacity hydropower development will be associated with large capacity. The construction of UHV EHV transmission lines matches.

According to statistics, the technologically exploitable installed capacity of hydropower resources in China is 574 million kilowatts, and the annual power generation is 2.5 trillion kilowatt-hours, accounting for about 15% of the total global hydropower resources.
