[Phnom Penh, Cambodia, June 11, 2025] Huawei Digital Power, in collaboration with SchneiTec, has successfully commissioned Cambodia's first-ever TÜV SÜD-certified grid-forming energy storage project, marking a key milestone in the country's transition toward a sustainable energy future.
Can battery energy storage be used to power Cambodia's grid?
“The battery energy storage system will showcase how large-scale deployment of innovative technology applications can be used to operate Cambodia's grid in the future and generate more renewable power.”
What is a battery energy storage system?
The battery energy storage system supported by the project is capable of storing 16 megawatt-hours of electricity and providing services to help with renewable energy integration, transmission congestion relief, and balancing of supply and demand, among others.
How can ADB help Cambodia in power system planning?
“The Grid Reinforcement Project, along with ADB's ongoing assistance to Cambodia in power system planning, shows that adequate, reliable, and environmentally sustainable power supply can be provided at a reasonable cost to support equitable development,” said ADB Country Director for Cambodia Sunniya Durrani-Jamal.
How much money does ADB give to Cambodia's energy sector?
Since 1994, ADB has awarded nearly $200 million in loans and grants to Cambodia's energy sector and provided $6 million in technical assistance. ADB funding has focused on expanding transmission and distribution networks and support for sector reforms and institutional capacity building.
The pilot battery energy storage project, located near the ADB-supported 100-megawatt (MW) National Solar Park, will come with on-the-job training. The government plans to increase solar photovoltaic generation capacity to 415 MW by 2022, up from 155 MW in 2019.
Does Cambodia need a new transmission infrastructure?
While Cambodia has made significant progress in expanding lower-cost power generation in the past 15 years, its existing transmission infrastructure is reaching capacity and needs to be expanded and reinforced to avoid supply interruptions.
