Cambodia’s clean energy transition is increasingly becoming an economic and industrial strategy, with renewable power, energy efficiency, electric vehicles and energy storage creating new opportunities for investment, skills development and higher value businesses.
At Clean Energy Week 2026, government officials, businesses and development partners highlighted the role of clean energy in strengthening Cambodia’s competitiveness, improving energy security and reducing exposure to international fuel price volatility.
Minister of Mines and Energy Keo Rottanak said renewable energy sources already account for more than 63 percent of Cambodia’s domestic installed power capacity, with the government targeting at least 70 percent by 2030.
The transition is also being supported by large scale solar, battery storage and pumped storage projects, while growing demand for skilled workers is creating another challenge for the emerging clean energy economy.
Clean Energy Becomes an Economic Strategy
Cambodia’s clean energy agenda is increasingly linked to industrial competitiveness rather than being viewed solely through an environmental lens.
EnergyLab Asia describes clean energy as a major economic opportunity for Cambodia, noting that manufacturers and exporters face growing pressure from buyers and investors to demonstrate lower carbon production and more sustainable supply chains.
For Cambodia’s export oriented economy, reliable and increasingly low carbon electricity could become an important factor in attracting investment into manufacturing, agro processing, electronics, automotive components and other industries.
The transition can also reduce exposure to imported fossil fuel prices by increasing the role of domestic renewable electricity.

Cambodia Targets 70% Renewable Energy by 2030
According to Keo Rottanak, renewable sources currently account for more than 63 percent of domestic installed power capacity.
The government aims to raise that share to at least 70 percent by 2030.
Hydropower and solar currently account for much of Cambodia’s renewable generation capacity.
The government is simultaneously developing energy storage and grid flexibility to accommodate a larger share of variable renewable generation.

More Than 1,100 MW of Solar Planned
Cambodian companies are expected to deliver more than 1,100 MW of solar capacity in a single cluster by the end of 2026, accompanied by 500 MW of battery storage, according to Keo Rottanak.
The combination of generation and storage is significant because solar output varies throughout the day.
Battery systems can store electricity when renewable generation is high and release it when demand increases or renewable production falls.
This makes storage an increasingly important part of Cambodia’s renewable energy strategy.
Battery Storage Strengthens Grid Flexibility
The Asian Development Bank approved a $63.44 million financing package in June 2026 for a utility scale battery energy storage project in Cambodia. The project involves a 250 MW/500 MWh battery system designed to improve grid stability, reliability and renewable energy integration.
The ADB says the project will also support Cambodia’s growing electricity demand from industrial zones, agro processing facilities and urban areas.
The project is designed to help manage peak loads and fluctuations in renewable electricity while strengthening the wider transmission system.
Source note: Cambodia’s state news agency AKP reported the 250 MW/500 MWh project as being in Kampong Chhnang, while the ADB project documentation identifies the battery system at the Takeo substation south of Phnom Penh. The location should therefore be independently confirmed before publication if precise project geography is important.
Upper Tatay Adds 1,000 MW of Pumped Storage
Cambodia is also developing large scale pumped storage capacity.
Construction has begun on the 1,000 MW Upper Tatay Pumped Storage Hydropower Project in Koh Kong province. The project is designed to provide energy storage, peak load management and greater flexibility for the electricity system.
Pumped storage functions as a large scale energy storage system by using electricity during periods of lower demand to pump water to an elevated reservoir and generating electricity when demand rises.
This can complement solar and other variable renewable energy sources.
Clean Energy Could Strengthen Export Competitiveness
The economic case for clean energy extends into Cambodia’s manufacturing sector.
EnergyLab Asia says clean electricity can help export industries respond to growing requirements for lower carbon production and sustainable supply chains. The organisation specifically identifies garment manufacturing, food processing and electronics assembly among sectors that could benefit from cleaner electricity.
For international manufacturers, access to reliable electricity with lower emissions can increasingly form part of investment decisions.
This creates a potential link between Cambodia’s energy policy and its strategy to attract higher value manufacturing investment.
New Investment Opportunities Across the Energy Value Chain
The clean energy transition is also creating opportunities beyond electricity generation.
Potential areas include:
- Solar power development
- Battery energy storage
- EV assembly and components
- EV charging infrastructure
- Energy efficiency services
- Grid technology
- Renewable energy engineering
- Energy management
- Equipment maintenance
- Waste management
- Clean energy technology services
EnergyLab Asia argues that Cambodia could also participate in the broader clean energy supply chain by developing local components, services and technical expertise.
The Cambodian Investment Board has similarly identified green and digital sectors as areas with potential for investment and economic growth.
Skills Could Become a Constraint
The expansion of clean energy technologies is creating demand for workers with new technical capabilities.
EnergyLab Asia’s research identifies significant skills gaps in Cambodia’s renewable energy and energy efficiency sectors. Its assessment found that employers often struggle to find candidates with practical experience, while training programmes need stronger links with industry.
The organisation also highlights the need for nationally recognised certification standards for occupations such as solar installers and designers.
The skills challenge extends beyond solar.
Cambodia’s EV transition will require technicians and engineers with specialised knowledge of electric vehicle systems, charging infrastructure and related technologies. EnergyLab Asia currently estimates that reaching Cambodia’s EV target will require at least 15,000 additional skilled workers across emerging EV occupations.
Government and Industry Need to Build Skills Together
The clean energy workforce challenge cannot be addressed solely by expanding classroom training.
EnergyLab Asia recommends stronger partnerships between companies and educational institutions, industry participation in curriculum development, greater work placement opportunities and modernised training laboratories.
Its Clean Energy Internship programme already connects Cambodian university and TVET students with companies in renewable energy, EVs and energy efficiency to provide practical industry experience.
This type of industry based training could become increasingly important as clean energy investment expands.
Clean Energy and Cambodia’s Long Term Resilience
Clean Energy Week 2026 uses the theme “Clean Energy for Energy Security and Economic Resilience.”
The theme reflects the growing connection between energy policy and economic stability.
More domestic renewable generation can reduce dependence on imported fossil fuels, while storage and grid investments can help improve electricity reliability.
At the same time, clean energy infrastructure can create new markets for Cambodian businesses and help industries respond to changing requirements from international buyers and investors.
Angkor Times Analysis
Cambodia’s clean energy transition is increasingly developing into an industrial competitiveness strategy. The combination of more than 63 percent renewable installed capacity, a 70 percent 2030 target, large solar projects, battery storage and pumped storage shows that the challenge is moving beyond simply adding renewable generation. For investors, the opportunity extends across power generation, storage, EVs, energy efficiency, engineering and supporting services. For manufacturers, cleaner and more reliable electricity could become increasingly relevant to export market access and investment decisions. The main constraint will be execution: Cambodia will need sufficient grid infrastructure, technical skills, financing, standards and local supply chain capacity to convert clean energy investment into broader economic value.
