6 FAQs about [Small hydropower station]
What is a small hydropower station?
The small hydropower station is generally built on medium or small rivers with a small basin area and without water concentration. It doesn’t change water quality and volume, and basically has no effect on the survival and reproduction of biological species of the rivers.
What is a small hydropower plant (shp)?
There is no globally unified definition for SHP. The International Center for Small Hydropower defines it as hydropower plants with an installed capacity of no more than 10 MW. By this definition, the global SHP resources total 217 GW. In 2016, there were approximately 78 GW of SHP capacity installed in 160 countries and territories.
What is small hydropower in China?
In China, the small hydropower means the hydropower stations have an installed capacity of not more than 50 MW , . The capacity limit of small hydropower is closely related to the development of Chinese National Economy, especially the rural economy and the electricity consumption level of rural areas.
How does a hydropower station work?
These hydropower stations independently operated with small capacity and simple devices, and transmitted electricity in low-voltage.
How many small hydropower stations are there?
906 small hydropower stations have the capability of daily regulation with the installed capacity of 3.146 GW, and the storage capacity of their reservoir is 8.27 billion m 3. The planning of small hydropower stations in each planning region can refer to Table 6. Table 6. Small hydropower stations planned in the 12th Five-Year period (2011–2015).
Why is small hydropower important?
For more than a century, small hydropower (SHP) development worldwide has been closely associated with rural electrification in remote mountainous areas that do not have access to power grids. As a mature and cost-effective technology, SHP can provide relatively stable and cheap electricity for local residents [1, 2].
