In recent years the concept of clustering large amounts of electrical generating capacity (10–50 thousand megawatts) into one geographic site has been suggested as an alternative to dispersed siting of electric power plants. Such large concentrations of power generation have been called energy parks or energy centers.
According to factors such as industrial structure, functional type, and carbon emission scenario, industrial parks can be divided into five categories: production
The park is reported to include an Energy Storage Technology Research Institute, an energy storage module production line, a 100MW/400MWH large-scale
