The Asian Development Bank has authorized a $63.44 million financing package to accelerate the integration of renewable energy into the national power grid of Cambodia. This initiative is designed to strengthen grid stability and enhance energy security while supporting the growth of cross-border power trade in Southeast Asia.
Strengthening Grid Stability and Renewable Energy Integration
The Utility-Scale battery energy storage project will facilitate the construction of a 250-megawatt/500-megawatt-hour battery storage system at the Takeo substation. This facility will capture excess renewable energy and dispatch it back to the grid to manage peak loads and stabilize fluctuations. Such infrastructure is essential to meet the increasing demand for electricity from industrial zones, urban districts, and agro-processing facilities in the southern regions of the country.
By improving grid interconnectivity with Vietnam, the battery storage project contributes to the ASEAN Power Grid’s objective of achieving fully integrated electricity operations by 2045.
ADB Country Director for Cambodia Yasmin Siddiqi said, “By strengthening the power grid with advanced battery storage, we are helping the country unlock more renewable energy while ensuring that families, farmers, and businesses benefit from safe, stable, and affordable electricity.”
Advancing a Sustainable Power System and Regional Goals
Currently, the nation’s power sector depends heavily on imported fuel, leaving it exposed to external price volatility and supply disruptions caused by geopolitical tensions. This battery storage project supports the national target of reaching 70% renewable energy capacity by 2030. Once operational, the facility is expected to prevent approximately 27,700 tons of greenhouse gas emissions every year, significantly aiding the renewable energy integration.
In addition to physical infrastructure, the battery storage project will bolster the capacity of Electricité du Cambodge (EDC), the state-owned utility, to manage advanced electrical systems. It also promotes technical skills development and seeks to increase female participation in leadership and technical roles within the sector.
The $63.44 million financing includes a $40 million concessional loan and a $5 million grant from the Asian Development Bank, complemented by $18.44 million in cofinancing from the Green Climate Fund and the United Kingdom through the ASEAN Catalytic Green Finance Facility.
