Wholesale wind prices fell for the fifth straight month last month in what was the best June on record for electricity demand generated by wind, according to Wind Energy Ireland.

The 30 per cent share of electricity demand met by Irish wind farms in June was up slightly when compared to June 2024 and was also a record month for Irish solar farms.

The 939 GWh generated by wind farms represented an almost 18 per cent increase from the 771 GWh generated last June, according to the report, which is based on EirGrid's SCADA data.

The average wholesale price of electricity per megawatt hour declined to €95.21 last month, the first time the average has been below €100 this year and the lowest level recorded since April 2024.

On days last month with the most wind power, the average cost of a megawatt-hour of electricity was €67.15, but the average rose to €115.06 on days when the country was reliant on fossil fuels.

“Affordability is critically important to Irish families and businesses," said Noel Cunniffe, chief executive of Wind Energy Ireland.

“Since 2000, renewable energy has saved electricity consumers nearly €1bn, according to recent research by Baringa. It is clean, it is secure, and it supports communities in rural Ireland.”

“Every time a wind turbine or a set of solar panels is generating electricity, it is pushing down wholesale electricity prices and increasing our supply of clean energy.”

Based on data provided by Green Collective, Kerry wind farms provided more electricity than any other county last month, with 105 GWh of power, around 11 per cent of the country’s wind energy.

Kerry was followed by Cork (83 GWh), then Mayo (65 GWh), Galway (64 GWh) and Offaly (61 GWh).

“Last year, wind farms like those in Kerry, Cork and Mayo helped Ireland save more than €1.2bn on gas spending," said Cunniffe.

“Rather than importing hundreds of millions of euros of gas, Irish wind farms ensured money stayed where it belongs, at home, supporting Irish workers and businesses.”

“To meet the needs of our growing economy, we need to accelerate the delivery of new wind farms, and we are committed to working with the government to help make this happen.”

The report confirms that wind energy generated 939 GWh in June, up from 771 GWh during the same month last year.
