Cambodia Unveils 1,000 MWh Battery Storage Plant, Largest in Southeast Asia
PHNOM PENH, March 13, 2026 — Cambodia has officially launched Southeast Asia’s largest battery energy storage system (BESS) with a total capacity of 1,000 megawatt-hours, marking a major step toward strengthening the country’s energy stability and renewable power integration.
The project, developed by SchneiTec, is designed not only to store clean electricity but also to enhance the reliability of Cambodia’s national power grid, officials said.
The facility allows surplus electricity generated from solar and wind power during the daytime to be stored and used later, particularly at night, helping reduce reliance on fossil fuels and supporting Cambodia’s transition toward cleaner energy sources.
Energy experts say the project also positions Cambodia as a regional leader in the deployment of “grid-forming” technology, an advanced system that helps stabilize electricity networks with a higher share of renewable energy.
Prior to the launch, the largest battery energy storage facility in Southeast Asia was located in Malaysia, with a capacity of around 400 megawatt-hours, meaning Cambodia now holds the top spot in the region.
The new project is part of Cambodia’s broader strategy to expand renewable energy capacity and improve grid resilience as electricity demand continues to grow across the country.
