This project consists of three energy storage technologies: lithium iron phosphate, high-voltage cascaded lithium battery, and all-vanadium liquid flow. The total capacity of the project is 250MW/1000MWh. Among them, the installed capacity of all-vanadium liquid flow is 11.5MW/70MWh (discharge capacity). This project is one of the few in the industry with a discharge duration of 6 hours. After the project is completed, it will fully utilize the long-duration energy storage characteristics of all-vanadium liquid flow. 

Since its first delivery of a 6-hour discharge project to a large listed manufacturing company in Zhejiang Province in 2023, Huantai Energy Storage has successively delivered multiple 4-hour and above discharge projects in Zhejiang, Guangdong, Shandong, Hebei, Xinjiang and other regions, covering various application scenarios such as 4-hour discharge, constant power discharge for 4 hours, discharge for 5 hours, and discharge for 6 hours. It provides users with two integrated solutions: stationary type and full container type. It has accumulated rich experience in the product design, scheduling and operation and maintenance of long-duration energy storage.
