Power Plants in Cambodia

Cambodia has 25 power plants mapped on the OverWatts open energy atlas — the 82nd-largest fleet of the 155 countries that hold any, and under 0.1% of the world's mapped total. Of these, 14 operating and 11 under construction or proposed. Operating generation capacity totals 3.7 GW across 14 utility-scale plants of 100 MW and above. The largest is Sambor hydroelectric plant (2.6 GW).

The largest owner-operators are Electricite du Cambodge (4), Royal Group (3) and China Huadian Group Co Ltd (2) — Electricite du Cambodge alone is named on 16% of them. Half of Cambodia's power plants in service predate 2017 (median commissioning year of the 14 with a known date), 7 came online in the past decade and the oldest still listed is Kamchay hydroelectric plant, dating from 2011. 11 are in the pipeline, led by Sambor hydroelectric plant (2.6 GW), proposed. They account for 50% of every energy asset OverWatts maps in Cambodia.
