JA Solar's 5MW/10MWh commercial and industrial energy storage power station project in Yangzhou was successfully connected to the grid and put into operation

Recently, the 5MW/10MWh industrial and commercial energy storage power station project of Jingshan Park in Yangzhou Base of JA Solar was successfully connected to the grid and put into operation. The project relies on the BG series 1500V liquid-cooled energy storage system independently developed, designed and integrated by JA Solar Technology. It consists of 3 energy storage units and 1 centralized control unit, and is connected to the grid through 10kV. The capacity of each DC prefabricated cabin is 3.354MWh, and the rated charge and discharge power is 1725kW. The system adopts a highly intelligent BMS battery management system to fully detect the operating parameters of the battery cells and improve the operating efficiency of the system; the advanced liquid cooling management system is optimized and designed to control the temperature difference of the battery cells to be less than 3°C, ensuring that the battery can operate in a mild environment for a long time; the battery pack system protection level reaches IP67 and has module-level detection.

In terms of operation mode, the project adopts a two-charge and two-discharge operation mode per day, charging at low electricity prices during low electricity consumption, and discharging during peak electricity consumption to supply enterprise production, achieving the effect of peak shaving and valley filling, effectively reducing the enterprise's electricity costs and promoting the efficient use of energy. More importantly, the project not only brings tangible economic benefits to the enterprise, but also has important significance for ensuring the safety and stability of the power system, promoting the consumption of renewable energy, and helping to achieve the "dual carbon goals".

The successful grid connection and operation of the 5MW/10MWh energy storage project at the Jingshan Park in Yangzhou is JA Solar's active response and in-depth practice to the "Global Green Industrial and Commercial Low-Carbon Development Initiative". At a time when carbon neutrality has become a global consensus, JA Solar will continue to leverage its advantages in photovoltaics and energy storage to set a benchmark for promoting the green transformation of the manufacturing industry, and lead more companies to join the "Global Green Industrial and Commercial Low-Carbon Development Initiative" to work together to create a better future of sustainable development.
