Power Quality in Antigua and Barbuda

Antigua and Barbuda is a small island nation in the Caribbean Sea, known for its stunning beaches, crystal-clear waters, and rich history. The country is home to a population of just over 100,000 people and relies heavily on tourism as a significant contributor to its economy. To support the tourism industry and other economic activities, reliable access to electricity is crucial. While the network has improved recently, the country still seems to experience frequent voltage fluctuations and power outages.

Power Sector in Antigua and Barbuda

The Antigua Public Utilities Authority (APUA) is responsible for generating, transmitting, and distributing electricity in Antigua and Barbuda. The APUA generates electricity using diesel generators, and the company is currently exploring renewable energy sources to diversify the energy mix.

The reliability of the electricity supply network in Antigua and Barbuda has been a concern for many years. The country experiences frequent power outages due to various factors, including equipment failure, maintenance issues, and natural disasters.

In recent years, the APUA has been working to improve the reliability of the electricity supply network. The company has invested in upgrading its infrastructure, replacing ageing equipment, and implementing measures to reduce power outages. These efforts have resulted in a significant improvement in the reliability of the electricity supply network.

However, despite the improvements, power outages still occur, especially during the hurricane season. Hurricanes can cause extensive damage to the electricity infrastructure, leading to prolonged power outages. In 2017, Hurricane Irma caused widespread power outages in Antigua and Barbuda, leaving many communities without electricity for several days.

The APUA has implemented measures to mitigate the impact of power outages on the community. The company has set up emergency response teams to restore power in the event of an outage quickly, and it provides regular updates on the status of power restoration efforts.


In conclusion, the electricity supply network in Antigua and Barbuda has seen significant improvements in recent years. However, the network’s reliability is still a concern, especially during the hurricane season. The APUA has taken steps to improve the infrastructure, equipment, and emergency response measures to reduce power outages and restore power quickly. With continued investment in renewable energy sources and infrastructure, the electricity supply network in Antigua and Barbuda can become more reliable and sustainable in the long run.

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:
