On December 23 local time, Malaysia's first large-scale battery energy storage system (BESS) project—Sejingkat 60MWac BESS Project, undertaken by China Energy Engineering Group Jiangsu Power Design Institute Co., Ltd. (JSPDI) as the EPC contractor—was successfully connected to the grid. This milestone marks yet a significant achievement in green energy cooperation between China and Malaysia.

The project is situated within the Sejingkat Coal-Fired Power Plant in Kuching, the capital of Sarawak, with an installed capacity of 60MW/80 MWh. It employs a prefabricated cabin-type air-cooled lithium iron phosphate battery energy storage system, characterized by high stability, long lifespan, and superior thermal management performance, making it particularly well-suited to Malaysia's hot and humid climate. The system is equipped with 22 battery cabins and 11 power conversion systems (PCS) to form a network, simplifying control logic while significantly improving operational and maintenance efficiency. Furthermore, the project is integrated with advanced battery energy storage technologies and a highly intelligent management system, providing robust support for the integration and optimized utilization of renewable energy.

Upon completion and commissioning, the project will revitalize the traditional coal-fired power plant. It is designed to achieve two charge-discharge cycles per day, provide frequency regulation responses within 100 milliseconds, and offer an annual peak-shaving capacity of 2190 MWh. This will serve as a critical contribution to optimizing local energy allocation and enhancing grid reliability.
