Kuala lumpur: The Santong Battery Energy Storage System (BESS) project, developed by Tenaga Nasional Berhad (TNB), represents a significant advancement in strengthening electricity grid stability and supporting Malaysia's energy transition agenda. The project, which boasts a capacity of 100MW/400MWh, was inaugurated by Deputy Prime Minister Datuk Seri Fadillah Yusof, who also serves as the Minister of Energy Transition and Water Transformation.
According to BERNAMA News Agency, Fadillah highlighted that the Santong BESS project is among Malaysia's earliest large-scale utility battery energy storage system initiatives. This effort is designed to integrate renewable energy sources more seamlessly into the national electricity supply system. The project aligns with the National Energy Transition Roadmap, focusing on diversifying the country's energy mix and addressing supply requirements.
Fadillah stated that as renewable energy sources, such as solar, become more prevalent, ensuring grid stability is crucial. The BESS technology acts as a stabilizer, guaranteeing not only sufficient energy supply but also maintaining the grid's overall stability. Recognized as Malaysia's first smart energy bank with grid-forming technology, the system exemplifies advanced energy management solutions.
The Deputy Prime Minister praised TNB for completing the project in less than a year, demonstrating the company's capability in developing essential energy infrastructure. The Santong BESS project, which cost approximately RM380 million, officially began operations on April 17 and is expected to have a lifespan of up to 15 years.
The system is designed to supply electricity for up to four hours during power outages, supporting the electricity needs of about 40,000 residents on the East Coast and enhancing regional supply stability. Fadillah noted that the BESS functions as a large-scale 'power bank,' storing excess electricity and releasing it as needed, thus stabilizing grid frequency and reducing power disruption risks.
As Malaysia's first 'smart energy bank' connected to the national grid using grid-forming technology, the Santong BESS project serves as a pivotal learning platform for the energy sector. It aids in the development, operation, and integration of utility-scale energy storage technology, marking a vital step in Malaysia's energy transition journey.
