On December 23, local time, Malaysia's first large-scale electrochemical energy storage project, the Sejingkat 60 MW Energy Storage Station, successfully connected to the grid. This milestone represents a significant achievement in China-Malaysia green energy cooperation. The project was implemented by China Energy Engineering Group Jiangsu Institute under an EPC (Engineering, Procurement, and Construction) contract.
The 60 MW/80 MWh project, situated in Kuching, the capital of Sarawak, employs a prefabricated, cabin-style, air-cooled lithium iron phosphate (LiFePO4) battery storage system. It comprises 22 battery cabins and 11 PCS (Power Conversion Systems) for grid connection, simplifying control logic and enhancing operation and maintenance efficiency.
Incorporating advanced battery storage technology and an intelligent management system, the project offers high automation levels, effectively supporting the integration and optimization of renewable energy. Once operational, it will be capable of performing two charge-discharge cycles daily and providing a 100-millisecond frequency regulation response. This will significantly contribute to optimizing energy distribution and enhancing grid reliability in the region.
