Leader Energy Group Berhad (“Leader Energy”) via its wholly-owned subsidiary Leader Solar Energy II Sdn Bhd (“LSE II”) and Plus Xnergy Services Sdn Bhd (“Plus Xnergy”) today 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 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.
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.
The NaS BESS alleviates intermittency challenges by enabling excess energy from the LSS farm to be stored in a safe and reliable manner, and discharged quickly in response to fluctuations for a stable and uninterrupted output of energy.
This also means energy that would otherwise be lost can be captured and stored, thereby increasing the amount of energy exported back to the grid.
“Leader Energy is proud to be at the forefront of Malaysia’s renewable energy landscape with the deployment of the country’s first-of-its-kind NaS BESS. This innovative 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,” said Dato’ Sean H’ng, Executive Deputy Chairman and co-Group CEO of Leader Energy.
