6 FAQs about [Energy storage power station unit investment]

What is the energy storage system?

The energy storage system includes 1×5 MW×2 h LiB, 1×2 MW×2 h VRFB. And the wind power of 99 MW had been put into operation in August 2012. The system is connected with the 35 kV bus. Through intelligent control, the system stores and releases power according to the coordinating with wind power.

How much subsidy should PV energy storage facilities be paid?

It specifies that energy storage facilities constructed synchronously with newly installed PV power generation should be paid a subsidy within 600 euro. In addition, the subsidy paid to energy storage facilities added to existing PV power generation should be within 660 euro/kW. What's more, price policies for PSS are relatively perfect in the EU.

How many kW is a solar energy storage system?

The wind power is 2×780 kW, the PV power is 300 kW. The energy storage system includes 1×2 MW×2 h PbAB, 1×500 kW×15 s SCES and 5×500 kW bidirectional converters. The system can realize the flexible shift between on-grid and off-grid operation. This bidirectional balance can guarantee the island's power utilization.

Does energy storage industry need a policy guidance?
