Despite this rapid and remarkable progress, some challenges still need to be addressed.
As of 2023, half of Cambodia's current electricity generation system continues to rely on fossil fuels, while the other half relies on hydropower.
To meet future energy demand, and to ensure access to cleaner sources of energy, the country has the opportunity to utilise its immense solar potential owed to Cambodia's advantageous natural environment.
This can help to decrease the country's electricity cost, (currently among the highest in the region), while supporting the government's ongoing work to decrease the tariff rates.
In addition, despite the impressive increase of rural village electrification noted above, reliability and access costs remain as opportunities for improvement.
During Cambodia's ASEAN Chairmanship in 2022, Cambodia's Prime Minister indicated the importance of the energy transition and the resulting need for "… policies, laws and regulations on clean energy, environmental protection and energy resource management…"
As Cambodia's energy transition continues to unfold, its government has begun to develop such policy initiatives to adopt variable renewable energy, and is opening the door to increased investment and development.
However, this policy environment remains nascent and much more remains on the transition pathway.
