Mr. Fergal Mulligan:

To put it in context, Storm Éowyn was probably the most extreme event ESBN has ever encountered, in its own words, and nearly 1 million homes were without a service. That was a lot more than the one-off dispersed nature of homes. Storm Éowyn had a massive effect across the western seaboard, so it was not just rural, remote towns and villages. I think ESBN estimates that the cost of Storm Éowyn was around €80 million to €100 million. It spent over €1.2 billion in 2025 on capital projects. That is the scale at which ESBN is spending money across the country every year.

As regards the impact on pricing of extreme storm events, while the numbers - €80 million to €100 million - are quite significant, smaller storms like Storm Ophelia and others result in much smaller amounts. The impact on network charges is negligible when you look at the scale.
