PETALING JAYA: Leader Energy Group Bhd and Plus Xnergy Services Sdn Bhd have announced the upcoming deployment of the country’s first sodium-sulfur (NaS) battery energy storage system (BESS).
Plus Xnergy will install and commission the 1.45MWh capacity BESS in LSE II’s large scale solar (LSS) farm located at Bukit Selambau, Kedah, the companies said in a joint statement.
The groundbreaking system utilises NaS battery technology which has greater energy density and can fully discharge without cell degradation. Its discharge duration of 6-18 hours is significantly higher than Lithium-based systems. As a result, it can store more energy in a smaller footprint while having longer life span at low maintenance, the statement added.
“This project marks Malaysia’s first utility-scale BESS connected to an operational LSS farm and is noteworthy as it will also be the first megawatt-scale grid connected battery used for LSS applications in peninsular Malaysia. This system’s scalable design allows for future expansion through a two-layer stacked container configuration, further enhancing energy security in a highly efficient manner.”
Leader Energy executive deputy chairman and co-group CEO Datuk Sean H’ng said the project will improve the efficiency and reliability of our solar energy operations at LSE II, while also demonstrating the broader potential of NaS BESS for grid firming and energy stability.
“Together with Plus Xnergy, we are setting a new benchmark for sustainable and advanced energy solutions in Malaysia’s energy sector," H’ng said.
Meanwhile, Plus Xnergy group CEO Ko Chuan Zhen said pioneering this NaS BESS system represents another milestone for us in supporting Malaysia’s net zero ambitions. He said the project will contribute to meeting the rising demand for stable renewable energy, particularly with Malaysia emerging as a regional data and cloud centre hub.
