Longyuan Power, a subsidiary of Chinese state-owned mining and energy company CHN Energy, has successfully connected the first phase of its pioneering 320 MW/640 MWh energy storage project in Zhaoyuan City, Shandong Province. The 200 MW/400 MWh energy storage project, the largest electrochemical storage facility in Shandong, is now operational and marks a major milestone for the region’s energy storage sector.
As one of the province’s most important projects, the station covers approximately 61 hectares and represents an investment of CNY 1.26 billion ($170 million). It integrates the latest hybrid storage technology, combining 60 battery systems with a capacity of 3.35 MW/6.7 MWh with a 3 MW/6 minute supercapacitor system, PCS systems, main transformers and a step-up substation. During off-peak hours, the system utilizes excess energy from the grid, improving overall efficiency.
