SCG, in collaboration with Toyota Motor Corporation (TMC), Toyota Motor Asia (TMA), Toyota Tsusho Corporation (TTC), and other partner companies, has announced the launch of a pilot Battery Energy Storage System (BESS) project for electric vehicles at Siam Toyota Industry Co., Ltd. (STM), located in the Amata City Industrial Estate, Chonburi Province.
As the global shift toward carbon neutrality accelerates, the demand for renewable electricity—particularly from solar and wind sources—has surged. However, the intermittent nature of these energy sources, which vary with weather and time of day, presents challenges for power system stability and efficient, continuous use. To address these issues, energy storage systems, combined with smart grid platforms and intelligent energy management, are increasingly essential for optimizing the use of clean energy. The adoption of such systems is expected to grow in tandem with the expansion of renewable energy.
Furthermore, the rising number of battery electric vehicles (BEVs) and hybrid electric vehicles (HEVs) has increased the need for effective reuse of used batteries. Repurposing EV batteries not only conserves resources and reduces electronic waste but also supports the principles of the circular economy by enhancing sustainability.
Mr. Parames Nisakornsen, Assistant Managing Director at SCG, thanked all stakeholders for their support, highlighting the role of the smart grid-enabled energy storage system in ensuring stable, cost-effective, and sustainable clean energy.
TMA CEO Masahiko Maeda also expressed gratitude to partners like SCG and Toyota Tsusho, emphasizing that reusing EV batteries will be vital in progressing toward a carbon-neutral society.

Toyota, together with its partners, launched the first project to develop and test the use of EV batteries as an energy storage system in Japan in May 2023 and has expanded its collaboration with SCG, its partner network in Thailand. The project will last for 2-5 years, with data collection and analysis to assess the potential for further expansion across Asia. This collaboration reinforces the commitment to create an innovative, decentralized energy storage system that promotes the circular economy concept of reusing EV batteries for maximum efficiency.
