Power Quality in Cambodia

As of the last decade, Cambodia has significantly improved its electricity supply network. Historically, Cambodia faced numerous challenges due to a lack of infrastructure and resources, leading to a limited and unreliable power supply. Power cuts were commonplace due to a limited generation capacity and an ageing and underdeveloped grid infrastructure. However, ongoing investments in power generation projects and grid improvements have helped to reduce the frequency and duration of power outages.

Power Sector in Cambodia

Cambodia’s power sector has been expanding rapidly, driven by increased urbanization, economic growth, and a commitment from the Cambodian government to ensure nationwide electrification. As of 2021, approximately 90% of the country’s villages had access to electricity, a considerable increase from just over 50% in 2009.

The country’s power generation comes from various sources, including hydroelectric dams, coal-fired power plants, and imported electricity from neighbouring countries. Over recent years, there has been a shift towards renewable energy, particularly solar power, to reduce reliance on imported electricity and fossil fuels.

The reliability of Cambodia’s electricity supply has improved significantly over recent years but remains a challenge, particularly in rural areas. The country has also faced challenges with voltage fluctuations and power quality, primarily due to the rapid growth in demand outpacing the development of the electricity infrastructure. However, the government and private sector’s concerted efforts have gradually improved the situation.

Cambodia has set an ambitious target of providing access to reliable and affordable electricity for all households by 2030. Achieving this goal will require ongoing investments in expanding the electricity grid, upgrading infrastructure, and developing new power generation projects.

There is also a growing focus on renewable energy. The government has launched several initiatives to promote solar and other renewable energy sources to increase energy independence and reduce greenhouse gas emissions.


In conclusion, while Cambodia’s electricity supply network has improved significantly over the last decade, challenges remain. The country continues to invest in its power infrastructure and renewable energy projects, improving the reliability and sustainability of its electricity supply network. These efforts will be crucial to Cambodia’s continued economic development and the well-being of its citizens.

About UsSINALDA logo

All mains powered equipment requires a supply which is maintained within certain limits. Too low and the equipment will malfunction, too high and the equipment could be serious damaged. In many developed and developing economies, power demand is outstripping supply, giving rise to large voltage swings, surges and brownouts in the supply.

Whatever your national or international power supply requirements, Sinalda (UK) can ensure your equipment receives the power it needs to operate efficiently and without interruption. To learn more about Sinalda (UK) and  the power protection solutions we offer please check-out the links below:
