Power Quality in Thailand

Thailand is a Southeast Asian country known for its stunning beaches, rich culture, and vibrant economy. The country has made significant progress in developing a reliable and sustainable electricity supply network in recent years, thanks to its strong commitment to energy security and investment in modernizing its power infrastructure.

Power Sector in Thailand

The electricity supply network in Thailand is managed by the state-owned utility, Electricity Generating Authority of Thailand (EGAT), which is responsible for generating, transmitting, and distributing electricity across the country. Thailand has invested heavily in modernising its power infrastructure, including the construction of new power plants and transmission lines, to ensure a reliable supply of electricity to its citizens and businesses.

Thailand has also made significant strides in renewable energy, particularly in solar power. The country has set ambitious targets to increase the share of renewable energy in its energy mix, aiming for 25% by 2037. Thailand has invested heavily in solar power, and the country’s solar farms generate enough electricity to power over 700,000 homes.

Thailand’s commitment to energy security and investment in modernising its power infrastructure has led to a reliable and sustainable electricity supply network. The country experiences minimal power outages, with an average of only 7 minutes of unplanned outage per year. This is due to a number of factors, including a robust electricity infrastructure, a diverse energy mix, and strong regulatory and policy frameworks.

To maintain the reliability of its electricity supply network, Thailand is taking steps to promote energy efficiency and demand-side management. The government has implemented policies to encourage the use of energy-efficient appliances and the implementation of smart grid technologies. Additionally, Thailand is exploring the use of energy storage systems and other technologies to improve the reliability of the electricity supply network and reduce the impact of power outages on citizens and businesses.


In conclusion, Thailand has made significant progress in developing a reliable and sustainable electricity supply network. The country’s commitment to energy security, investment in modernising its power infrastructure, and promotion of renewable energy sources has led to a reliable and sustainable electricity supply network. Thailand must continue to invest in improving its power infrastructure and increasing the efficiency of its electricity sector to ensure a reliable and sustainable electricity supply for its citizens and businesses.

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:
