Irish state-owned utility ESB has posted annual pre-tax profits of €636 million for 2025, a €70 million decrease on the prior year attributed to the impact of Storm Éowyn in January 2025, alongside record capital investment of €2.7 billion in critical energy infrastructure. The results reflect the group's continued programme of grid modernisation, renewable energy expansion, and decarbonisation across the island of Ireland.

Business Eye reported that ESB's capital investment represented a ratio of €4 invested in capital projects for every €1 of profit after tax earned, with the group forecasting approximately €20 billion in total investment over the next five years, of which up to €16 billion is directed to electricity networks on the island of Ireland.

Paul Stapleton, chief financial officer of ESB, said the results reflect the company's continued commitment to delivering substantial investment in critical energy infrastructure, and that its 2025 financial performance enabled record capital investment while retaining the financial strength to invest at even greater scale in the years ahead.

ESB Networks made over 38,000 residential connections in 2025, up 18 per cent on 2024. The year also saw the historic ending of coal generation at Moneypoint power station and the installation of over two million smart meters across Ireland.

ESB Group secured the rights to develop the 900 MW Tonn Nua offshore wind project off the coast of Waterford with Ørsted, while its solar portfolio includes 700 MW currently in development. The group's carbon intensity of power generation has fallen 53 per cent against a 2005 baseline.

ESB contributed €3.4 billion to the Irish economy in 2025 through payroll, taxes, dividends, and purchases from domestic suppliers, with a proposed dividend of €149 million. Employee numbers grew to over 10,000 during the year.
