Storm Éowyn leaves hundreds of thousands without power across Ireland and Northern Ireland

*Event date: 2025-01-24*

Storm Éowyn has left hundreds of thousands of homes and businesses without power across Ireland and Northern Ireland, with network operators warning that restoration could take more than a week in the worst-hit places.

The evidence packet describes the damage as unprecedented. It says the storm brought destructive winds, felled trees, blocked roads and knocked out major parts of the electricity grid. At one point, around 768,000 customers were without power across the country, while the number in Northern Ireland alone peaked above 280,000. Those are extraordinary figures for a single weather event and suggest major disruption well beyond a normal winter storm.

The packet also makes clear that the impact was not limited to electricity. Roads were blocked by fallen trees and debris, public transport was suspended during red warnings, schools and shops were closed, and flights were cancelled. In some areas, water supplies were also affected because treatment plants and pumping stations lost electricity. That created a second layer of disruption on top of the power outages.

Winds were severe enough to produce headline-grabbing measurements, including a provisional gust of 183 km/h in Connemara and another of 143 km/h in Killowen in County Down. Even without every local reading, the broader picture is obvious: infrastructure across the island was overwhelmed. Operators said crews could only begin full restoration work once the red weather warnings were lifted and conditions were safe.

The source excerpt also captures the official tone of the response. ESB Networks described the damage as unprecedented and said restoration would continue into the evening and then resume at first light. In Northern Ireland, NIE Networks told residents to stay clear of damaged equipment and fallen lines. That is standard safety advice, but in this case it reflects just how much debris and danger the storm left behind.

The most important detail for residents is that the recovery will not be quick. Some areas may have to wait for a week or more for electricity to return, and water service disruptions may also last for days. The storm’s physical damage will take time to assess, and even longer to repair.

For now, Storm Éowyn stands out not only for its raw wind speed but for the scale of its disruption: power outages, road closures, water interruptions and a restoration effort that will stretch far beyond the day of the storm.
