It is the largest grid-side individual energy storage station built in one continuous construction period. Covering an area of 58 mu (3.87 hectares), an equivalent to five and a half standard football pitches, the power station has a total installed capacity of 300 megawatts/600 megawatt-hours, occupying one-fifth of the total installed capacity of
The pumped storage power station (PSPS) is a special power source that has flexible operation modes and multiple functions. With the rapid economic development in China, the energy demand and the peak-valley load difference of the power grid are continuing to increase. Moreover, wind power, nuclear power, and other new energy
Power grids are increasing the volume of renewable energy generation from unpredictable sources such as solar and wind. As a consequence, the problem of increasing peak-to-valley load difference and the difficulty of renewable energy consumption is becoming more and more obvious. Energy storage power stations are an effective means to solve such
