Energy storage system investment policy

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.

Does the energy storage strategic plan address new policy actions?

This SRM does not address new policy actions, nor does it specify budgets and resources for future activities. This Energy Storage SRM responds to the Energy Storage Strategic Plan periodic update requirement of the Better Energy Storage Technology (BEST) section of the Energy Policy Act of 2020 (42 U.S.C. § 17232 (b) (5)).

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.

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.

What are the different types of energy storage policy?

Approximately 16 states have adopted some form of energy storage policy, which broadly fall into the following categories: procurement targets, regulatory adaption, demonstration programs, financial incentives, and consumer protections. Below we give an overview of each of these energy storage policy categories.

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.
