How long does a subsidy for energy storage stations last?
For new energy storage stations with an installed capacity of 1 MW and above, a subsidy of no more than 0.3 yuan/kWh will be given to investors based on the amount of discharge electricity from the next month after grid connection and operation, and the subsidy will not last for more than 2 years.
What is user-side energy storage?
1. Introduction User-side energy storage mainly refers to the application of electrochemical energy storage systems by industrial, commercial, residential, or independent powerplant customers (which in convenience we call "firms").
What is the energy storage policy?
The policy proposes to promote the large-scale application of energy storage, and support the integrated development of new energy sources such as photovoltaics and energy storage facilities.
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.
Can a subsidy policy be activated or terminated at an uncertain time?
The subsidy policy, however, can be activated or terminated at an uncertain time and therefore, the firms face additional policy uncertainty when making the decision. We derive the investment thresholds of the market spread that the firms use to make a decision on investing immediately or holding an option.
What if there is no government subsidy?
Without government subsidies, the uncertainty that firms face when making investment decisions is mainly due to the fluctuation in the peak-valley spreads. The fluctuation, however, is capped by a maximum set by the government to keep the stability of the electricity market.
