ESB (Electricity Supply Board) was established in 1927 as a statutory body in the Republic of Ireland under the Electricity (Supply) Act 1927. With a holding of 95%, ESB is majority owned by the Irish Government. The remaining 5% is held by the trustees of an Employee Share Ownership Plan. As a Strong, Diversified, Vertically Integrated Utility, ESB operates right across the electricity market: from generation, through transmission and distribution to supply of customers, with an expanding presence in the Great Britain generation market. In addition, we extract further value at certain points along this chain; supplying gas, using our networks to carry fibre for telecommunications and more. ESB is a leading Irish utility with a regulated asset base (RAB) of approximately €9 billion, 47% of generation in the all-island market and as a supplier of electricity to approximately 1.4 million customers throughout the island of Ireland. ESB will continue to grow the scale of its generation, trading and supply businesses so that it can compete within the all-islands competitive environment. ESB is focused on providing excellent customer service and maintaining its financial strength. As at 31st December 2017, ESB employed approximately 7,800 people.
