Cambodia — Energy Infrastructure

OverWatts maps 50 energy assets in Cambodia across 8 layers — the 87th-largest mapped base of 157 countries. They include 25 power plants, 7 cement plants and 6 iron ore mines. Operating generation capacity is 3.7 GW, led by coal at 40%.

The companies named on the most assets are Electricite du Cambodge (4), Royal Group (3) and Cambodia Natural Gas Corp (2), counting both ownership and operatorship. Half of Cambodia's mapped assets in service predate 2019 (median commissioning year of the 26 with a known date), 16 came online in the past decade and the oldest still listed is Kampot Cement Dang Tong Cement Plant, dating from 2008. 14 projects are under construction or proposed, led by Sambor hydroelectric plant (2.6 GW).
