Power Quality in Papua New Guinea

Papua New Guinea (PNG) is a country in the Pacific region with a population of over 8 million people. The latest information published by the World Bank would suggest that only just over 60% of the population have access to the electricity supply network. Where electricity via the grid is available, it is unreliable and limited primarily to urban centres. Power outages and brownouts are frequent.

Power Sector in Papua New Guinea

PNG has a mix of electricity generation sources, including hydropower, diesel generators, and gas-fired power plants. The country’s electricity supply network is managed by the state-owned company PNG Power, which is responsible for generating, transmitting, and distributing electricity in the country.

The electricity supply network in PNG faces several challenges, including inadequate infrastructure, limited financial resources, and limited access to modern technology.

The reliability of the electricity supply network in PNG is a major concern, with frequent power outages and load shedding being experienced in many parts of the country. This is due to a number of factors, including inadequate infrastructure, poor maintenance of power plants, and transmission and distribution lines, and limited fuel supplies for diesel generators. These challenges are particularly acute in rural areas, where access to electricity is limited, and power outages are more frequent.

The government of PNG is aware of the challenges facing the country’s electricity supply network and has developed several policies and initiatives to address them. These include investments in new power plants, upgrading existing infrastructure, and introducing renewable energy sources such as solar and wind power. The government has also encouraged private investment in the electricity sector to promote competition and improve the efficiency of the network.

Despite these efforts, there is still a long way to go to improve the reliability of the electricity supply network in PNG. The country needs significant investment to upgrade its infrastructure and expand access to modern technology. The government and private sector must work together to develop new energy projects, improve the efficiency of the existing network, and increase the availability of affordable and reliable electricity to the people of PNG.


In conclusion, PNG’s electricity supply network is still weak, and significant challenges need to be addressed. However, there is hope that with sustained investment and government support, the network’s reliability can be improved, and access to electricity can be expanded to more people across the country.

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:
