FESSIA

About FESSIA The Future Energy Storage & System Integration Alliance (FESSIA) is a regional alliance born out of the need to ensure ASEAN’s energy systems remain stable and resilient, enabling large-scale integration of variable renewable energy (VRE) while safeguarding grid stability and energy security. As ASEAN countries work towards meeting their net-zero ambitions over the coming decade, more variable renewable energy (VRE) such as solar and wind, will be integrated into their energy systems. When this happens, maintaining grid stability will become an increasingly critical challenge. Our Work FESSIA is a multi-stakeholder coalition that unites the renewable energy industry, think tanks, and academia to address grid flexibility and energy security challenges in a high VRE future. Through structured engagement using the “Route-to-Market” policy framework, we foster dialogue and shape policy that ensures a pathway for large-scale deployment of energy storage technology. By equipping civil society organisations with expertise and networks to engage in grid issues, FESSIA helps lead the development of flexible, reliable, and net-zero grids across ASEAN. Our Focus Areas We will focus on accelerating the deployment and integration of battery energy storage systems (BESS) across regional power grids from now till 2030. Beyond 2030, our efforts will expand to advance long-duration energy storage (LDES) technologies.
