Duodoma energy storage subsidy policy adjustment

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 do government subsidies help energy storage enterprises?

Government subsidies alleviate the financial constraints of energy storage enterprises. Government subsidies promote R&D investment in energy storage enterprises. Differentiated subsidy strategies can generate higher TFP improvement returns. Government subsidies are an important means to guide the development of the energy storage industry.

Do policy adjustments affect energy storage technology investments?

The findings of this study are as follows: 1) The frequency of policy adjustments and the magnitude of subsidy adjustments can both influence energy storage technology investments, but the magnitude of subsidy adjustments is more significant.

Will phase-down policy increase energy storage investment thresholds?

With an increase in adjustment policy frequency or subsidy magnitude under the phase-down policy, although the investment threshold of energy storage technology will all rise, the rise in investment thresholds is significantly different. Policy implementation should use more long-term, stable incentives.

Do government subsidies improve TFP of energy storage enterprises?

Government subsidies improve the TFP of energy storage enterprises. The government's “picking winners” subsidy strategy is effective. Government subsidies alleviate the financial constraints of energy storage enterprises. Government subsidies promote R&D investment in energy storage enterprises.

Do government subsidies affect the R&D of large-scale energy storage projects?

Government subsidies may have a stronger effect on the R&D of large-scale ESEs. Currently, the energy storage projects show a trend of continuous scale-up, and large ESEs are more likely to construct large-scale “wind power + PV + energy storage” projects.
