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 cities need a subsidy for energy storage?

Most cities do not have high profitability for energy storage to participate in peaking auxiliary services and urgently require policy subsidies. Specifically, under certain policy conditions, a subsidy of at least 0.0246 USD/kWh is necessary to motivate investors to invest effectively.

How does policy uncertainty affect energy storage technology investment in China?

Policy adjustment frequency and subsidy adjustment magnitude are considered. Technological innovation level can offset adverse effects of policy uncertainty. Current investment in energy storage technology without high economics in China. Subsidies of at least 0.169 yuan/kWh to trigger energy storage technology investment.

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.

Will China keep implementing policy incentives for energy storage?

To effectively guarantee its grid stability of renewable energy sources, the Chinese government is expected to keep implementing its policy incentives for energy storage in the near future. This particular dataset provides us with the technical specifications of an energy storage system and allows us to calculate the model parameters.

How much energy storage capacity will the IRA add in 2022?

The U.S. added more than 10.5 GWh and cumulated over 17 GWh of installed energy storage capacity in 2021. In 2022, there is optimistically projected 20 GWh of energy storage capacity, among which 85% come from the FTM market. The biggest impact of the IRA is that it includes standalone energy storage technology.
