ADB approves $52.72 million loan for Cambodia grid expansion project

The Asian Development Bank (ADB) has approved a loan of $52.72 million to support Cambodia’s Grid Expansion Project. The program aims to strengthen the national transmission network, integrate more renewable energy, and meet growing electricity demand with locally generated clean power.

Cambodia’s domestic electricity generation increased from 8.68 terawatt hours (TWh) in 2020 to 17.85 TWh in 2024. Over the same period, power imports declined from 3.06 TWh to 1.57 TWh, reflecting greater self-sufficiency.

The project will construct 55 kilometers of 230 kilovolt transmission lines between Pursat and Kampong Chhnang and upgrade nine substations across the country. These upgrades are intended to reduce transmission losses, improve grid reliability, and enable wider integration of solar and wind generation.

According to ADB, the initiative is aligned with Cambodia’s Power Development Master Plan (2022–2040) and National Energy Efficiency Policy (2022–2030). It is expected to enhance energy security while encouraging private sector participation in renewable energy.
