Energy storage development investment policy

What are China's energy storage incentive policies?

China's energy storage incentive policies are imperfect, and there are problems such as insufficient local policy implementation and lack of long-term mechanisms . Since the frequency and magnitude of future policy adjustments are not specified, it is impossible for energy storage technology investors to make appropriate investment decisions.

What is the investment threshold for energy storage in China?

At this stage, the investment threshold for energy storage to involvement in China's peaking auxiliary services is 0.1068 USD/kWh. In comparison, the current average peak and off-peak power price difference in China is approximately 0.0728–0.0873 USD/kWh.

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.

How to promote energy storage technology investment?

Therefore, increasing the technology innovation level, as indicated by unit benefit coefficient, can promote energy storage technology investment. On the other hand, reducing the unit investment cost can mainly increase the investment opportunity value.

Do policy adjustments affect energy storage technology investments?

The primary conclusions are summarized as follows: The frequency of policy adjustments and the magnitude of subsidy adjustments have different levels of impact on energy storage technology investments. The adverse effect of the subsidy adjustments magnitude is much more significant than the impact of the policy adjustments frequency.

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.
