What are the rewards for energy storage power stations

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.

Can electrical energy storage solve the supply-demand balance problem?

As fossil fuel generation is progressively replaced with intermittent and less predictable renewable energy generation to decarbonize the power system, Electrical energy storage (EES) technologies are increasingly required to address the supply-demand balance challenge over a wide range of timescales.

What is the energy storage subsidy?

The upper limit is 1 million yen for household and 0.1 billion yen for commercial consumers. The object of this subsidy is not only optimizing electricity system operation, but also evaluating the influence of large-scale production for battery costs. Compared with the US and Japan, EU started late in energy storage policies.

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.

How much does energy storage cost?

Calculated by Guotai Junan Securities in October 2013. The target cost for the marketization of energy storage industry was about 200 dollars/kW h, equivalent to 1246 yuan/kW·h. However, at present, the cost of PbAB is about 1000 yuan/kW·h and the cost of NaS battery, LIB is about 4000 yuan/kW·h.
