Wind energy accounted for 24% of Ireland’s electricity generation in July 2025, down from the 31% average recorded over the first seven months of the year.
Despite the drop, Wind Energy Ireland (WEI) has stated that it was the third-highest level of wind generation ever recorded for the month of July.
According to the latest figures, Irish wind farms generated a total of 786 gigawatt hours (GWh) last month.
For the first time this year, Cork overtook Kerry as the top-producing county, delivering 85GWh of electricity.
Kerry followed closely with 84GWh, while Offaly (54GWh), Galway (53GWh) and Mayo (51GWh) rounded out the top five.
Together, Cork, Kerry and Offaly contributed more than one quarter of Ireland’s total wind power output for July.
Electricity prices
The average wholesale price of electricity in July 2025 was €99.61 per megawatt hour (MWh), representing a 10% decrease from €110.94 in July 2024.
However, prices varied significantly depending on energy sources. On days with the highest levels of wind generation, the average cost fell to €84.80 per MWh, while on days when fossil fuels dominated, the average rose to €111.55 per MWh.
