Wind Farms provided 38% of Ireland’s total electricity in the first three months of the year, showing the ongoing growth of renewable energy.

The report by Wind Energy Ireland states that in March wind farm output accounted for 33% of total electricity demand, slightly below the average level for the month.

However, a record-breaking month for solar power generation compensated for the shortfall.

The most productive counties for wind energy in March were Kerry (135GWh), Cork (125GWh), Galway (89GWh), Mayo (87GWh), and Offaly (81GWh).

Wind power from the top three counties alone accounted for more than a quarter of Ireland’s total electricity usage last month.

Noel Cunniffe, CEO of Wind Energy Ireland, said: “Our members provided a third of Ireland’s electricity in March.”

“Every time a wind turbine is generating electricity, it is reducing our reliance on imported fossil fuels, helping to push down wholesale electricity prices and increasing our supply of clean energy to power our homes, businesses and local communities.”

“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.”

Total electricity consumption in March 2025 hit 3,673 gigawatt-hours (GWh), up from 3,598 GWh in the same month last year.

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 doubled to €165.19 on days when we relied almost entirely on fossil fuels.

Noel Cunniffe concluded: “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.”

“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.”
