Project scale: 9MW/4 5MWh Project address: Hangjin, Inner Mongolia Project completion time: August 2018 Project income: The estimated total investment of this project is about 35 million yuan (the actual investment will vary based on the project site conditions). After the energy storage system is put into operation, the Hangjin Power Generation #1 (#2) unit will become the best quality in Mengxi Power Grid One of the AGC frequency modulation power supplies, it is estimated that Hangjin Thermal Power #1 (or #2) will receive AGC compensation income totaling about 21 million yuan per year (the energy storage system runs for about 300 days per year, #1 (or #2) is about: (70,000 yuan) Project significance: In the AGC frequency modulation of the thermal power unit, the lithium battery energy storage system responds quickly according to the frequency modulation command, improves the AGC frequency modulation and effect, improves the stability and operating efficiency of the thermal power unit, and reduces the operating cost.
