Ireland achieved a major renewable energy milestone last month, as June 2025 became the most productive June on record for wind generation, according to the latest monthly report from Wind Energy Ireland (WEI). Wind farms supplied 30% of the country’s electricity demand, slightly higher than in June 2024, and solar generation also reached record levels.

This increase in renewable output came alongside a rise in overall electricity demand, which grew from 3,019 GWh in June 2024 to 3,151 GWh this year.

WEI CEO Noel Cunniffe praised the performance: “Our members delivered nearly a third of Ireland’s electricity in the first half of 2025, and June stood out as a particularly strong month for renewable generation. Wind remains Ireland’s leading source of renewable electricity, helping to reduce our reliance on imported fossil fuels and improving national energy security.”

The report also highlighted a positive trend in electricity pricing. The average wholesale electricity price fell for the fifth month in a row, reaching €95.21 per MWh—the lowest level since April 2024, and the first time in 2025 it dipped below €100. On days with strong wind generation, average prices dropped to €67.15/MWh, while on days when Ireland depended more heavily on fossil fuels, prices spiked to €115.06/MWh.

“Affordability is crucial for Irish families and businesses,” said Cunniffe. “A recent Baringa study shows that renewable energy has saved electricity consumers nearly €1 billion since 2000. It’s clean, secure, and supports rural communities across the country. Every time a wind turbine or solar panel generates power, it helps push down wholesale electricity prices and strengthens our clean energy supply.”

Regionally, wind farms in County Kerry led the way in June, producing 105 GWh—roughly 11% of Ireland’s total wind output. Cork followed with 83 GWh, then Mayo (65 GWh), Galway (64 GWh), and Offaly (61 GWh).

Cunniffe emphasized the economic impact of local renewable generation: “Last year alone, counties like Kerry, Cork, and Mayo helped Ireland save over €1.2 billion in gas expenses. Instead of spending hundreds of millions importing fossil fuels, Irish wind farms ensured that money stayed in the local economy—supporting jobs and businesses here at home.”

To meet the growing energy needs of the country, WEI is calling for faster development of wind and solar infrastructure. “We are committed to working with the Government to accelerate the build-out of new renewable projects,” Cunniffe added.

The report’s findings are based on SCADA data from EirGrid, analysis by MullanGrid, market data from ElectroRoute, and county-level generation figures from Green Collective.
