Best September on record for Irish wind farms – Wind Energy Ireland
New figures show that wind generation in Ireland was the highest on record for a September month.
This is according to Wind Energy Ireland, which published its monthly wind energy report as
Ireland’s Wind Energy Expo 2025 continues in the RDS in Dublin.
Wind Energy Ireland said that wind energy provided 35% of the country’s electricity last month while solar and other renewables provided an additional 7% for a total renewable share of 42%.
Wind power generation in September totalled around 1,129 gigawatt-hours (GWh), with Kerry once again leading the way as the country’s top county for wind energy production (129 GWh). It was followed by Cork (117 GWh), Galway (95 GWh), Derry (77 GWh) and Mayo (71 GWh).
Prices on days with the most wind power saw the average cost of a megawatt-hour of electricity fall to €62.01 per megawatt hour and rise to €117.37 on days when the country relied almost entirely on fossil fuels.
Noel Cunniffe, CEO of Wind Energy Ireland, said that wind energy is the country’s number one source of renewable energy.
“Renewables provided over 40% of our electricity last month and that figure is set to rise as we build more wind and solar farms. The more wind energy that we 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,” Mr 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,” he stated.
He also said that every time a wind turbine is generating electricity it is pushing down the wholesale electricity prices – which leads to lower electricity bills for consumers.
“Research published in 2025 shows that between 2020 and 2023 renewable energy cut energy bills by an average of €320 per person. That’s an example of how investing in clean energy can deliver real savings for households and as Ireland grows its renewable energy capacity, those savings will continue to grow,” he added.
