Energy storage subsidy electricity price

Are energy storage subsidy policies uncertain?

Subsidy policies for energy storage technologies are adjusted according to changes in market competition, technological progress, and other factors; thus, energy storage subsidy policies are uncertain. In this section, the investment decision of energy storage technology with different investment strategies under an uncertain policy is studied.

What is the cost of energy storage?

The cost of energy storage consists of three components. Firstly, there are conventional fixed costs, which are one-time costs incurred during the investment in energy storage. Secondly, there are operational and maintenance costs, which represent the continuous costs incurred throughout the entire lifespan of the energy storage system.

Does energy storage subsidy affect microgrid diffusion?

The periodical fluctuation results of microgrid diffusion under different storage subsides have indicated that different energy storage subsidies have different effects on microgrid diffusion, and the electricity price subsidy for energy storage has more significant effect than the initial cost subsidy to promote microgrid diffusion.

How much does battery energy storage cost in China?

The discount rate r is set at 0.08, as referenced in the China Energy Storage Network. The current corporate income tax rate in China τ is around 25%. The Bloomberg New Energy Finance suggests that the investment cost of battery energy storage in 2022 is $261 per kWh. Therefore, we calculate the initial investment cost (I) to be 3.36 million RMB.

How does price affect energy storage technology investment income?

The price has considerable uncertainty, which directly affects the energy storage technology investment income. Investment in energy storage technology is characterized by high uncertainty . Therefore, it is necessary to effectively and rationally analyze energy storage technology investments and prudently choose investment strategies.

How to choose the best energy storage investment scheme?

By solving for the investment threshold and investment opportunity value under various uncertainties and different strategies, the optimal investment scheme can be obtained. Finally, to verify the validity of the model, it is applied to investment decisions for energy storage participation in China's peaking auxiliary service market.
