Cambodia’s current domestic electricity supply is dominated by coal power plants and hydropower, at 41% and 44%, respectively, while solar is at 6% and growing. According to the Ministry of Mines and Energy, Cambodia aims to have an additional 495 MW from seven solar power plants. .
Despite Cambodia’s recent growth and development, 1 out of 5 households in rural areas remains off-grid, meaning they don’t have access to power provided by utilities, and are. .
Residents of Cambodia’s populated cities and urban areas are frustrated by power shortages and power cuts during the dry season. But even that is a privilege residents of many isolated villages cannot relate to – the number of households living off-grid amounts to. [pdf]
