Cambodia: electricity in context
Electricity generation in Cambodia reached 17.8 TWh in 2025. That is similar to Sri Lanka. More than half of it, 56.6%, came from coal; hydropower was a distant second with 29.9%.
40.9% of the country’s power came from renewable sources: 73rd of 158 countries. This puts it 7 points above the world average of 33.8%. It is also above the average for Asia (27.3%). Generating one kWh emits about 499 g CO₂e here (world average: 458 g). The grid is more carbon-intensive than the world average. On carbon intensity, Cambodia ranks 98th of 158 from the cleanest.
Over the past decade coal added more generation than any other source (+7.9 TWh since 2015, plus 9.2 percentage points of share). Measured by share of the mix, solar power gained most, up 10.6 percentage points. The net effect: renewables lost 8.1 percentage points of share since 2015. Total generation grew by 13.3 TWh over the same period. Carbon intensity, however, rose from 448 to 499 g/kWh (+11%).
Against the global trend, coal’s share has risen by 9.2 percentage points in ten years, to 56.6%.
Wind and solar together provided 10.6% of electricity (solar 10.6%, wind 0%), compared with 17.3% worldwide. Per person, that is 106 kWh of solar electricity a year, versus a global average of 338 kWh. Solar first passed 1% of the mix in 2019.
Cambodia generates 995 kWh of electricity per resident each year, 26% of the global average. Imports cover around 21% of demand: Cambodia bought 4.6 TWh more electricity than it exported.

Power plants in Cambodia
The WRI Global Power Plant Database lists 16 utility-scale plants in Cambodia with a combined capacity of 1.5 GW. Hydro plants account for the largest slice (60% of listed capacity). The biggest single plant is Sihanoukville CIIDG power station (405 MW, Coal). The database was last updated in 2021, so newer wind and solar farms and rooftop PV are under-represented.
