Should energy storage investors and policymakers consider incentive policies?

Furthermore, the findings of this study are particularly helpful for energy storage investors and policymakers, not only in China but also in other countries. For example, before designing incentive policies for the energy storage industry, policymakers should consider the intended effect of policy interventions on their targets.

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.

Do policy adjustments affect energy storage technology investments?

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.

Should you invest in future energy storage technologies?

Additionally, the investment threshold is significantly lower under the single strategy than it is under the continuous strategy. Therefore, direct investment in future energy storage technologies is the best choice when new technologies are already available.

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.
