Southeast Asia''s emerging energy storage opportuniti
Wärtsilä has delivered a number of projects in the region, including Singa-pore''s first-ever pilot grid-scale battery energy storage system (BESS) and several large-scale projects in the
Rapid increases in electricity consumption in Southeast Asia caused by rising living standards and population raise concerns about energy security, affordability and environmental sustainability. In this study, the role of short-term off-river energy storage (STORES) in supporting 100% renewable electricity in Southeast Asia is investigated.
Indonesia's successful securing of a World Bank loan for developing pumped storage facilities exemplifies how government backing is facilitating large-scale energy storage projects.
Countries like Singapore, the Philippines, and Thailand are leading the adoption of battery energy storage systems technology, with numerous projects under development. The technology's versatility in applications ranging from grid services to behind-the-meter installations for commercial and residential use is driving its adoption.
In 2025, BloombergNEF (BNEF) released its annual Battery Storage System Cost Survey, which found that global average turnkey energy storage system prices had fallen 40% from 2023 numbers to US$165/kWh in 2024.
