Power outages today

Around 2.5 million homes, farms and businesses in the Republic of Ireland are connected to a single electricity grid. The map above shows live power outages reported across the 26 counties, with the estimated time of restoration for each incident.

Whether a fault is caused by a storm, an equipment failure or planned maintenance, this page consolidates the live map, the wider context on Ireland's electricity network and the contacts to report a power cut.

Ireland's electricity grid: one national network, 2.5 million customers

The Republic of Ireland has a single national electricity distribution network, operated by ESB Networks. It serves 2.5 million customers and connected 37,558 new homes and businesses to the grid in 2024.

More than 1.9 million smart meters have been installed across the country and are now read remotely every day, providing real-time visibility on outages at street level.

The networks operator is separate from the electricity suppliers customers pay each month, such as Electric Ireland, Bord Gáis Energy or SSE Airtricity. The same grid serves every customer regardless of the chosen supplier.

A 23,000 km underground cable network spanning every county

The Irish distribution network includes 23,000 km of underground cables, 150,000 km of overhead lines, 2.2 million poles and more than 640 high-voltage substations.

It operates at 110 kV in the Dublin area, and at 38 kV, 20 kV and 10 kV across the rest of the country. More than 6 billion euros have been invested in the grid over the last decade.

Storm Éowyn left 768,000 customers without power in January 2025

Storm Éowyn struck Ireland on 24 January 2025 and became the most damaging weather event ever recorded on the Irish electricity grid, with a peak of 768,000 customers without power.

More than 1,600 field technicians were deployed, including crews called in from the United Kingdom and France through European mutual aid agreements. The event prompted the launch of a national Winter Resilience Plan for 2025.

Planned outages versus unplanned faults: how power cuts are classified in Ireland

Planned outages are scheduled in advance for grid works or new connections, and affected customers receive notice. Unplanned faults cover equipment failures, third-party damage from construction or road accidents, and weather damage.

A third category, emergency outages, is triggered when power must be cut immediately for safety reasons, for instance after a fallen line or a substation fire.

Power outages in Dublin, Cork, Galway: where faults concentrate

Dublin concentrates the largest volume of incidents in absolute numbers, driven by population density and a network that is mostly underground, where faults come from equipment failure rather than weather.

Rural counties such as Galway, Mayo and Donegal record more outages caused by wind and trees on overhead lines. Cork combines both profiles, with an urban core and an exposed rural hinterland.

Reporting a power outage: dial 1800 372 999, available 24/7

The official emergency line for power outages in Ireland is 1800 372 999, open 24/7. From abroad, dial 00353 21 238 2410. Callers are asked for the MPRN (Meter Point Reference Number), the 11-digit code printed on the electricity bill.

For visible electrical hazards such as fallen cables, smoking transformers or sparking equipment, dial 999 or 112 first to alert emergency services before contacting the networks operator.

When power cuts also take down broadband, mobile and TV in Ireland

Power cuts in Ireland can affect fixed broadband, mobile networks and TV services when local exchanges or cell sites lose power. Eir owns the largest fixed-line network through Open Eir, while Vodafone, Three and Virgin Media also operate their own infrastructure.

Mobile cell sites generally hold a battery backup of two to four hours, but a multi-day outage can take whole rural areas offline for voice and data, even when the wider mobile network is intact.

Tracking power outages in Ireland: live map, app and social media

The networks operator runs an official outage app and updates incidents in real time on social media during major events. This page combines the live map, the wider context and the emergency contacts on a single URL.
