ESB

ESB (Electricity Supply Board) is Ireland’s foremost energy company and a diversified utility that operates across the entire electricity value chain. Established in 1927 as a statutory corporation under the Electricity (Supply) Act 1927, it is majority‑owned by the Irish Government, with the remaining stake held through an Employee Share Ownership Plan. ESB develops and operates generation assets, including large thermal and hydroelectric plants and substantial wind and other renewable capacity on the island of Ireland, and holds around 25% of generation in the all‑island market. Through ESB Networks, it owns and maintains the high‑voltage transmission system and the medium‑ and low‑voltage distribution network in Ireland, acting as transmission asset owner, distribution asset owner and distribution system operator, and serving roughly 2.5 million customers over a network exceeding 200,000 km. ESB also owns Northern Ireland Electricity Networks. On the supply side, Electric Ireland provides electricity, gas and energy services to more than 1.3 million households and businesses across Ireland, while Customer Solutions businesses and the So Energy brand supply residential customers in Great Britain. ESB Energy in Great Britain offers public EV charging in cities such as London, Coventry and Birmingham, and delivers energy‑efficiency and decarbonisation projects for large businesses. ESB ecars owns, operates and maintains a public EV charging network across Ireland capable of supporting about 1,400 vehicles simultaneously. ESB International delivers engineering and consultancy services to utilities worldwide, with projects in over 120 countries. ESB’s strategy, “Driven to Make a Difference: Net Zero by 2040,” commits the group to achieving net‑zero emissions by 2040 by developing and connecting renewables, modernising grids, enabling electrification of transport and heat, and investing in initiatives such as the conversion of Moneypoint power station into a renewable energy hub and the efficiency and hydrogen‑readiness upgrade of the Dublin Bay gas‑fired plant. The group underpins this transition with strong finances, including a regulated networks asset base of about €14 billion and record annual capital investment in critical low‑carbon infrastructure.
