During the 15 years to December 2018, Cambodia’s power source capacity increased from 208 MW to 2,650 MW with energy delivered increasing from 814 GWh to 9,307 GWh (35 percent coal, 48 percent hydro, 2 percent fuel oil, and less than 1 percent renewable energy, other than large hydro). A 2018 World Bank report found that 97.6% of Cambodian households have access to at least one source of electricity, and the country is targeting 100 grid access by the end of 2030.

Electricity in Cambodia is amongst the most expensive in the region. By December 2019, the amount of imported electricity in Cambodia had fallen to 14.5% from 22% in 2016, although energy imports are likely to continue for several years, as the development of new high-voltage lines between Cambodia and neighboring countries is continuing.

Solar power is emerging as an energy source with considerable potential for Cambodia. In April 2020, a new 60 MW solar farm located in Kampong Chhnang began operations, increasing Cambodia’s grid-connected PV capacity to 150 MW. Cambodia has two other operational PV parks with 10 MW and 80 MW capacities respectively, and has approved 410 MW of new projects.
