Energy storage power station storage price

What is pumped storage power station (PSPS)?

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.

What is pumped Energy Storage?

The PSPS is the best tool for energy storage. The pumped storage has the function of energy reserve, and it solves the problem of electricity production and consumption at the same time, and not easy to store. Thus, it can effectively regulate the dynamic balance of the power systems in electricity generation and utilization.

Is a PSPS a good energy storage system?

Compared with them, the PSPS investment is lower, the service life is longer, and the efficiency of energy conversion is more stable. As a result, the PSPS is currently the most mature and practical way for large-scale energy storage in the power system. The PSPS is the optimal tool for load regulation.

What is reversible pumped storage unit (PSPS)?

The PSPS is both the load and power source. The reversible pumped storage unit is used as a pump to consume the temporarily surplus power when the energy demand is low. On the contrary, the unit can run as a generator when the energy demand is high. This is not possessed by any other type of power plants.

Should Chinese power systems develop pumped storage systems?

The result shows the urgency of developing the PSPS in Chinese power systems that have given priority to thermal power, and the energy resources need the wide-range optimal allocation within the system. The development cycle of the pumped storage is long, and at least 8–10 years are needed from the planning to the completion.

What is the storage capacity of Gangnan hydropower station?

This PSPS uses Gangnan reservoir as the upper reservoir with the total storage capacity of 1.571×10 9 m 3, and uses the daily regulation pond in eastern Gangnan as the lower reservoir with the total storage capacity of 3.5×10 6 m 3. For the application of the pumped storage unit, Gangnan hydropower station owns the ability of load regulation.
