ESB profits down by 10% due to impact of Storm Eowyn

The ESB Group saw a 10% drop in profit after tax last year due to “unplanned costs” relating to Storm Eowyn, the Cabinet heard on Tuesday.

Storm Eowyn in January 2025 is recognised as one of the most dangerous and destructive storms in living memory in Ireland.

It brought galeforce/stormforce winds, including severely damaging and destructive gusts of over 184 km/h, a record for Ireland.

The impacts of Storm Eowyn were particularly severe and prolonged in remote and rural communities across the western seaboard, the north-west and midlands of the country.

It saw a million customers of ESB and NIE without electricity supply across the island of Ireland – with a week’s long interruption to power and water supplies in parts.

ESB’s annual report was taken to Cabinet on Tuesday and a Government spokesman said it has reported profit after tax of 636 million euro in 2025, compared to 706 million in 2024.

ESB had previously said it incurred additional operating costs of the order of an aggregate 100 million euro in reconnecting customers and remediating the damage to networks’ infrastructure following Storm Eowyn.
