Our Heritage 

Since 1927, our parent company, the Electricity Supply Board of Ireland - ESB, has brought the transformative power of electricity to the cities, towns, villages, and the remote corners of Ireland. This revolutionary transformation has underpinned the country’s economic and social change from a largely underdeveloped rural nation to one of the world's most successful global economies.

In 1975, ESB International, was formed to bring that expertise, skill, and leadership to clients worldwide.

We understand the challenges that face utilities because we’re part of one.
