PETALING JAYA: Leader Energy Group Bhd marked the groundbreaking of its 100MW/400 MWh grid-scale battery energy storage system (BESS) project in Pajam, Negeri Sembilan, under Malaysia’s Battery Energy Storage System bidding programme (MyBeST).
The ceremony marked the project’s transition into the construction phase and the group’s continued expansion into grid-scale energy storage.
Developed through Leader Energy Storage Sdn Bhd under MyBeST, the project is scheduled for commissioning in 2027. It will provide additional flexibility to Peninsular Malaysia’s grid, supporting the integration of more renewable energy while helping manage changes in electricity supply and demand.
The development builds on Leader Energy’s practical experience with its 1.45MWh sodium-sulfur BESS pilot at the Leader Solar Energy II (LSE II) solar plant in Bukit Selambau, Kedah. Integrated with the plant’s 20MWac grid-connected photovoltaic system, the pilot demonstrates how battery storage can store excess solar electricity and discharge it when required, supporting more effective use of renewable energy.
Leader Energy executive deputy chairman and group CEO Datuk Sean H’ng said, “Our experience at LSE II has given us practical insight into integrating battery storage with solar generation. With Leader Energy Storage project here in Pajam, we are building on that foundation as we expand into grid-scale storage and contribute to the next stage of Malaysia’s energy transition.”
He added they are proud to contribute infrastructure that supports a reliable grid and enables more renewable energy to be integrated into Malaysia’s electricity system.
Administered by the Energy Commission, MyBeST comprises four grid-connected BESS projects, each with a capacity of 100MW/400MWh. Together, the projects represent 400MW of power capacity and 1,600MWh of energy storage capacity, with commissioning scheduled for 2027.
The MyBeST programme supports Malaysia’s long-term goals of reducing reliance on fossil-fuel peaking plants, lowering system costs over time and achieving the National Energy Transition Roadmap target of 70% renewable energy capacity by 2050.
For Leader Energy, the groundbreaking marks a further step in its development as an integrated renewable energy infrastructure platform, bringing together renewable generation, energy storage and power transmission capabilities across Asia
