New figures today show that more than a quarter of the country's electricity came from wind farms last month while solar power and other renewables accounted for an additional 6%.
Wind Energy Ireland's latest monthly report also said that wind energy met 31% of Ireland's electricity demand over the first eight months of 2025 and that Kerry has reclaimed its place at the top of the wind energy leaderboard.
Based on data published by Green Collective, Kerry produced 83 GWh and was closely followed by Cork (78 GWh), Galway (61 GWh), Mayo (48 GWh) and Derry (44 GWh). Together, the top three counties provided a quarter of Ireland's wind power last month.
Today's report also found that wind farms delivered big savings for consumers. On the days with the most wind power on the system, wholesale electricity prices more than halved compared to days when we were forced to rely on imported gas.
Noel Cunniffe, CEO of Wind Energy Ireland, said that while there was a drop in electricity generation from wind in August compared to last year’s figure, wind farms have performed well since the beginning of 2025 by providing nearly a third of the country's power.
"Wind energy is our number one, and most affordable, source of renewable energy. The more wind energy that we can produce here in Ireland, the more we can secure our own supply of clean, affordable, electricity and reduce the need to import expensive fossil fuels from other countries," he added.
The Wind Energy Ireland report reveals that the average wholesale price of electricity in Ireland per megawatt-hour during August was €96.38, down 4% from €100.44 in the same month last year.
Prices on days with the most wind power saw the average cost of a megawatt-hour of electricity fall to €67.31 per megawatt hour and more than double to €156.43 on days when we relied almost entirely on fossil fuels.
"At a time when our economy is under threat from tariffs, energy costs and global uncertainty, Irish wind farms are a ready-made solution," Noel Cunniffe said.
"Rather than importing hundreds of millions of euros of gas, Irish wind farms ensure money stays where it belongs, at home, supporting Irish workers and businesses. We have the natural resources, we have the project pipelines and we have the ambition to deliver a competitive, zero-carbon society," he added.
