Power Quality in Nepal

Nepal, a landlocked country in South Asia, has made significant progress in electrifying and expanding access to electricity in recent years. Despite this progress, Nepal’s electricity supply network still faces challenges regarding reliability and accessibility, particularly in rural areas.

Power Sector in Nepal

Nepal’s electricity supply network primarily relies on hydropower, which accounts for more than 80% of the country’s installed capacity. In 2019, the electrification rate in Nepal was around 93%, up from just 18% in 1995.

Despite this progress, Nepal’s electricity supply network is still relatively underdeveloped, with limited transmission and distribution infrastructure in many parts of the country. This lack of infrastructure and the country’s rugged terrain can make it challenging to expand the network and improve reliability in some areas.

Reliability of the Supply Network

The reliability of Nepal’s electricity supply network varies depending on the location. In urban areas, the network is relatively reliable, with fewer power outages and voltage fluctuations than in rural areas. However, in rural areas, power outages and voltage fluctuations are common, and many households still rely on traditional energy sources like kerosene and firewood.

To address these challenges, the Nepalese government has implemented several initiatives to improve the reliability of the electricity supply network. For example, the government has invested in expanding transmission and distribution infrastructure and upgrading existing power plants to improve efficiency and reliability. Additionally, the government has sought to diversify the country’s energy mix by promoting solar and wind power use.

Investing in the Network

Nepal’s government and utility companies are making significant investments in the country’s electricity sector to address the network’s challenges. These investments include constructing new power plants, expanding transmission and distribution infrastructure, and adopting new technologies such as smart grids and renewable energy sources.

Nepal is also working with neighbouring countries to develop regional power grids, enabling the country to import and export electricity. For example, the Nepal-India Power Exchange Project is a regional power grid that aims to improve energy security and reduce greenhouse gas emissions by promoting the development of renewable energy sources.


In conclusion, Nepal’s electricity supply network has made significant progress in recent years but still faces challenges regarding reliability and accessibility, particularly in rural areas. The Nepalese government is taking steps to address these challenges, including investing in new generation capacity, transmission and distribution infrastructure, and new technologies. As Nepal continues to develop its electricity sector, it will be critical to improve the network’s reliability, expand access to electricity, and diversify the energy mix to support sustainable economic growth and development.

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:
