Soliciting opinions on energy storage subsidy policy

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.

Are government subsidies effective in reducing energy storage financing constraints?

Large ESEs with sufficient collateral and high technological maturity of their energy storage products are more likely to receive government subsidies and external financing from the banking sector. As a result, government subsidies are more effective in alleviating the financing constraints of large-scale ESEs.

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.

Do government subsidies increase total factor productivity of energy storage enterprises?

Based on panel data of Chinese 101 energy storage enterprises from 2007 to 2022, this paper examines the effectiveness of government subsidies in the energy storage industry from the perspective of total factor productivity (TFP). The results unveil that government subsidies significantly increase the TFP of ESEs.

Will subsidies increase the TFP of energy storage companies in China?

The development of China's energy storage industry is in the stage of rapid expansion and technology iteration, different types of subsidies may all contribute to the R&D innovation and scale expansion of ESEs, and thus increase the TFP of ESEs.
