More than a quarter of Ireland’s electricity came from wind farms last month, while solar and other renewable sources added a further 6 %, according to the latest monthly wind energy report from Wind Energy Ireland (WEI).

The report highlights that wind farms delivered significant savings for consumers. On days with the highest levels of wind generation, wholesale electricity prices were cut by more than half compared to days when Ireland had to rely almost entirely on imported gas.

Over the first eight months of 2025, wind power has met 31 % of Ireland’s electricity demand, with Kerry reclaiming its position at the top of the county wind energy rankings.

Electricity prices fall with wind generation

The average wholesale price of electricity in August was €96.38 pernMWh, down 4 % from €100.44 in the same month last year.

On the windiest days, prices dropped as low as €67.31/MWh, while on days dominated by fossil fuels they more than doubled, averaging €156.43/MWh.

“While there was a drop in wind generation in August compared to last year, wind farms have performed strongly so far in 2025 by supplying nearly a third of the country’s electricity,” said Noel Cunniffe, CEO of Wind Energy Ireland.

“Wind energy is our number one, and most affordable, source of renewable power. The more we generate here in Ireland, the more we secure a supply of clean, low-cost electricity and reduce the need to import expensive fossil fuels,” he added.

County leaders in wind generation

Wind generation in August totalled 870 GWh. Data from Green Collective shows Kerry leading with 83 GWh, followed by Cork (78 GWh), Galway (61 GWh), Mayo (48 GWh) and Derry (44 GWh). Together, the top three counties produced a quarter of Ireland’s wind power last month.

Call for investment in State agencies

The publication of the WEI report comes alongside the launch of its Pre-Budget 2026 submission, which calls for a €100 million Climate Recruitment Fund, financed by €10 million annually over ten years. The fund would strengthen staffing levels in key State agencies such as planning authorities and the Commission for Regulation of Utilities (CRU).

“To deliver more clean power, we need to build more wind farms, and that means ensuring our planning authorities and regulators have the resources they need,” Cunniffe stressed.

“Budget 2026 is a chance to invest in the foundations of an energy-independent Ireland. That’s why we are calling for the creation of a Climate Recruitment Fund to boost capacity across State agencies and accelerate the transition,” he concluded.

The report’s findings are based on EirGrid SCADA data compiled by MullanGrid, market data provided by ElectroRoute, and renewable generation figures from Green Collective.
