36% of the country's electricity was provided by wind farms last month, new figures show.
The figures from Wind Energy Ireland show that solar energy and other renewables provided an additional 5%, bringing the total renewable share to 41%.
The average wholesale price of electricity in October fell to €100.70 per megawatt-hour (MWh), down from €123.45 per MWh during the same month last year.
The latest figures show that wind power generation in October 2025 totalled around 1,229 gigawatt-hours (GWh).
Kerry maintained its position as Ireland’s top county for wind energy production, followed by Cork, Galway and Derry.
"We are fortunate in Ireland to have natural resources like wind that can generate more affordable, clean electricity to power our local communities," said Noel Cunniffe, CEO of Wind Energy Ireland.
"It is great to see that renewables once again provided over 40% of the country's electricity last month, with wind farms accounting for the vast majority of that power.
"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," he added.
