Cambodia's Major Leap in Energy Transition: Launch of Nation's Largest 1,000 MWh Battery Storage System

Cambodia takes a major step in its energy transition with the official launch, on March 13, 2026, of the country's largest battery energy storage system (BESS) project.

With a capacity of 1,000 megawatt-hours, this infrastructure, located in the SchneiTec solar farm in Krakor district, Pursat province, strengthens the stability of the national grid and accelerates the integration of renewables

A Historic First for Energy Stability

Developed by SchneiTec, a key player in renewable energy in Cambodia, this BESS marks a decisive turning point. Integrated into the national grid, it stores excess solar electricity produced during the day to release it at night, thereby minimizing the risks of outages and imports of fossil fuels. "This project goes beyond clean energy storage; it consolidates the reliability of electricity supply for households and industries," states the company's press release.

This achievement builds on SchneiTec's previous advances as a local pioneer, which had already inaugurated in 2025 a first 12 MWh storage station with Huawei, certified by TÜV SÜD and equipped with grid-forming technology. This innovative system, tested in weak grid conditions, positions Cambodia among ASEAN leaders in advanced electricity flow management.

Toward the Goal of 70% Clean Energy by 2030

This launch directly supports the government's ambition to raise the share of clean energy to 70% by 2030. By improving grid quality and enabling massive injection of solar and wind power, the BESS serves as a strategic pillar against supply volatility. SchneiTec, founded in 2015 and leader in Cambodian solar farms—including the kingdom's largest—demonstrates its ability to combine industrial scale with technological innovation.

A Promising Regional Context

In a Cambodia where solar and storage projects are multiplying—like the 23 initiatives recently approved by the authorities, including two large-scale BESS—this 1,000 MWh infrastructure surpasses previous efforts. It complements international initiatives, such as the ADB project funded with $60 million to stabilize the grid and evacuate excess renewables. Phnom Penh is consolidating its role as a pioneer in Southeast Asia, as the kingdom's energy demand explodes with rapid industrialization.
