Kerry and Cork tops as wind farms generate 35% of Irish electricity
Wind farms generated 35% of Ireland's electricity over the first four months of 2025, according to industry body Wind Energy Ireland.
Average wholesale power prices fell for the third month in a row in April. The average wholesale cost of electricity has fallen from €167.51 in January to €111.11 in April, though this remains higher than prices for the same period last year. On days in April with the most wind power the average cost of a megawatt-hour of electricity was €101.33 but this rose to €124.20 on days when we relied almost entirely on fossil fuels.
Demand for electricity during April 2025 fell marginally to 3,307 gigawatt-hours (GWh) from 3,315 GWh in the same month last year. The share of electricity demand met by wind energy last month was 28%, and over the four months has provided more than a third of Ireland's demand, Wind Energy Ireland chief executive Noel Cunniffe said.
"At a time when our economy is under threat from tariffs, energy costs and global uncertainty we have a solution, ready-made, here in Ireland. Irish wind farms have cut bills by almost €1.7bn since 2020, that's around €320 per person," said Mr Cunniffe.
Mr Cunniffe said Ireland spends €1m every hour importing fossil fuels, and estimated that tripling our onshore wind capacity would drive costs down. "Onshore wind energy is Ireland's most affordable source of new electricity. The more wind energy that we can develop, the less we rely on imported fossils fuels, and the better protected Irish families and businesses are from a volatile fossil fuel market," he said.
Data from Green Collective showed Kerry wind farms provided most electricity in April with 111 GWh of power, around 12 per cent of the country's wind energy, followed by Cork (91 GWh), then Galway (63 GWh), Mayo (62 GWh), and Tyrone (59 GWh).
Earlier this month, minister for climate, environment, energy, and transport Darragh O'Brien announced that work has started on a new national map to identify locations where future wind farms can be national Designated Maritime Area Plan (DMAP) for offshore wind will be developed by the Department of the Environment, Climate and Communications and will involve extensive data-gathering and public consultation. It is due to be completed by the end of 2027.
In April, a study by planning and environmental consultancy MKO commissioned by Wind Energy Ireland calculated that Ireland's capacity for further onshore wind development could triple.
