Irish wind farms provided 38% of the country’s electricity over the first three months of 2025.

The latest figures, published by Wind Energy Ireland, show that the demand for electricity during March 2025 increased slightly to 3,673 gigawatt-hours (GWh), up from 3,598 GWh in the same month last year.

The share of electricity demand met by wind farms last month, at 33%, was slightly below the normal average for wind energy in March but the shortfall was partially compensated by a record month for solar power.

Noel Cunniffe, CEO of Wind Energy Ireland, said: “Every time a wind turbine is generating electricity, it is reducing our reliance on imported fossil fuels. 

"Irish wind farms produce power without burning imported fossil fuels, which means we can cut our carbon emissions at the same time as we cut our fuel imports and our prices.” 

The report also shows that the average wholesale price of electricity in Ireland fell for the second consecutive month to €131.80 per megawatt-hour in March. Prices last month on days with the most wind power saw the average cost of a megawatt-hour of electricity fall to €112.26, but nearly double to €165.19 on days when we relied almost entirely on fossil fuels.

Kerry wind farms led the way last month, producing more wind energy than any other county (135 GWh). They were followed by Cork (125 GWh), then Galway (89 GWh), and Mayo. Together, the top three counties produced over a quarter of Ireland’s wind power in March.

“Irish wind farms, and particularly those in Kerry, are playing an enormous part in reducing Ireland’s carbon emissions and creating funding for rural communities to invest in the priorities they choose for their area like sports grounds and community spaces," said Mr Cunniffe. 

“As new wind farms connect to the grid the amount of money invested by our members in local communities will only grow. By developing our renewable energy sector, we can build an Ireland that is energy independent, delivering warm homes and cleaner air.”
