Global GridCambodia's energy mix and electricity
🇰🇭 In 2025, Cambodia generated 17.8 TWh of electricity. The largest source was coal at 57%, followed by hydro (30%) and solar (11%). In total, 41% came from low-carbon sources (nuclear and renewables) and 59% from fossil fuels.
On average, each kilowatt hour produced about 499 grams of carbon dioxide (CO₂), close to the world average of 458 grams in 2025. That makes Cambodia the 97th cleanest of 158 countries that generate at least 1 TWh a year.
Electricity demand was 22.4 TWh. Cambodia imported 4.63 TWh more electricity than it exported, equal to 21% of its demand.
Since 2000, electricity generation has grown by 3,608%, from 0.48 TWh. The low-carbon share went from 6% to 41%. The biggest rise was in coal, from 0% to 57% of generation. The biggest fall was in oil and other fossil fuels, from 94% to 3%. Carbon intensity fell from 625 to 499 grams per kWh.

Energy security score
Moderate. Cambodia ranks 84th of 158 countries and 20th of 46 in Asia. The score shows how well a country could keep electricity affordable and on if fuel supplies were disrupted. It is based on 4 of the 5 measures.
| Measure | Score |
|---|---|
| Produces its own energy No reliable figure exists for Cambodia, so this measure is left out and the other four count for more. | n/a |
| Variety of power sources How evenly generation is spread across nine sources. The largest, coal, made 57%. | 65 |
| Little reliance on imported power Net imports were 21% of demand; each 1% takes off 2 points. | 59 |
| Low-carbon power Nuclear and renewables made 41% of generation. | 41 |
| Low gas and oil use Gas and oil made 2.5% of generation; the score is 100 minus that share. | 98 |
The five measures are weighted 30%, 20%, 20%, 15% and 15%. How the score works.
Oil and gas pipelines
Global Energy Monitor lists 89 km of oil and gas pipelines operating in Cambodia, 0 km being built and 0 km proposed (lengths measured along the mapped routes; a pipeline crossing borders counts in full for each country). For liquefied natural gas (LNG), shipped by sea, it lists 0 import terminals operating (1 more being built or proposed).
