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.
