AKP Phnom Penh, September 18, 2025 --

The Asian Development Bank (ADB) has approved a US$52.72 million loan for the Grid Expansion Project in Cambodia. The project will strengthen the country’s transmission network to integrate more renewable energy into the national grid and help meet rising electricity demand with cleaner, locally generated power.

Cambodia has expanded its domestic electricity generation rapidly, doubling output from 8.68 terawatt hours (TWh) in 2020 to 17.85 TWh in 2024, said ADB in a news release issued this morning, adding that over the same period, reliance on imported electricity dropped from 3.06 to 1.57 TWh. This progress reflects the country’s growing energy self-reliance and the potential of renewable sources to support its development goals.

“Reliable and affordable electricity is the backbone of Cambodia’s growth story,” said ADB Country Director for Cambodia Ms. Jyotsana Varma. “This project is about more than building transmission lines—it is about connecting people, schools, hospitals, and businesses to a cleaner and more resilient energy future. By bringing more renewable energy into the grid, Cambodia can power opportunities for its people while protecting the environment for generations to come.”

According to the source, Cambodia’s grid was built for conventional power and now needs expansion to handle growing solar and wind. The project will build 55 kilometres of 230-kilovolt transmission lines between Pursat and Kampong Chhnang, and upgrade nine substations across the country. These investments will strengthen transmission capacity to deliver renewable energy to demand centres nationwide, improve reliability, and encourage greater private investment.

Aligned with Cambodia’s Power Development Master Plan (2022–2040) and the National Energy Efficiency Policy (2022–2030), the project will help reduce transmission losses, and enhance energy security.

ADB is a leading multilateral development bank supporting inclusive, resilient, and sustainable growth across Asia and the Pacific. Working with its members and partners to solve complex challenges together, ADB harnesses innovative financial tools and strategic partnerships to transform lives, build quality infrastructure, and safeguard our planet. Founded in 1966, ADB is owned by 69 members—50 from the region.
