(1) The investment installation is carried out according to the investment model agreement, and the user only needs to bear the cost of the regional pipeline and ancillary facilities according to the agreement, and there is no economic burden on others.

(2) Because the project uses urban off-peak electricity for energy storage operation, the cost of heating and cooling shall implement the unified charge regulations of Xuzhou price department in the year of vacuum boiler structure.

(3) Electric energy storage heating and cooling system has been used in many countries in Europe and the United States, and has been widely used in various industries such as urban heating and factories since 1930. The maximum temperature of hot water in this project can reach 150℃, and the refrigeration can reach -15℃. The electric energy storage heating and cooling project is a regional operation, with the region as an independent body, and is not limited by the vacuum boiler model time and external factors. Heating and cooling can be carried out at any time as needed, with little energy loss and maximum efficiency.

(4) After the implementation of this project, it will help to fill the valley and peak, ensure the economic and safe operation of the power grid, and increase the financial revenue of the power sector.

(5) The energy storage project covers a small area, saves the user's land resources and improves the land utilization rate.
