China ups pumped hydro storage capacity
Under this system, water is pumped from a lower elevation reservoir to a higher elevation by using low cost, off-peak power production such as wind power during the night to run the pumps, and is released to generate power when demand peaks during the day or when electricity prices are higher.
The State Grid started building a 1.2 GW pumped storage hydropower plant in southern Jiangxi province, the first phase of a planned 2.4 GW capacity expansion that will have a total cost of about 5 billion yuan US $732.3 million.
China had only 14.55 GW of pumped storage hydropower capacity at the end of 2009, according to the State Grid.
China's total power generating capacity was 874 GW at the end of 2009.
