Wind farms generated 38% of Ireland’s electricity during the first quarter of 2025, according to new data released by Wind Energy Ireland. The report highlights a strong performance from renewable energy sources, with Kerry emerging as the leading county for wind energy production in March.
Kerry wind farms produced 135 gigawatt-hours (GWh) of electricity last month, more than any other county. Cork followed closely with 125 GWh, while Galway, Mayo, and Offaly rounded out the top five producers, generating 89 GWh, 87 GWh, and 81 GWh respectively. Collectively, the top three counties accounted for over a quarter of Ireland’s total wind energy generation in March.
Although wind accounted for 33% of the country’s electricity demand last month—slightly below the seasonal average—the shortfall was partially offset by record-breaking solar power generation, Wind Energy Ireland said.
Electricity demand also saw a modest year-on-year increase, rising to 3,673 GWh in March from 3,598 GWh in March 2024.
The report also noted a continued drop in wholesale electricity prices. The average cost fell to €131.80 per megawatt-hour (MWh) in March, marking the second consecutive month of price reductions. On days when wind generation was highest, the price dipped further to €112.26 per MWh. In contrast, on days heavily reliant on fossil fuels, the cost surged to €165.19 per MWh.
Noel Cunniffe, CEO of Wind Energy Ireland, emphasized the economic and environmental benefits of wind energy. “Every time a wind turbine is generating electricity, it’s reducing our dependence on imported fossil fuels, cutting carbon emissions, and helping to lower electricity prices,” he said.
Cunniffe also highlighted the broader impact of wind energy on rural communities, particularly in counties like Kerry. “Wind farms are not only powering homes and businesses—they’re funding community initiatives, from sports facilities to local infrastructure,” he said. “As more wind farms come online, these benefits will grow, helping us build a cleaner, more energy-independent Ireland.”
The report reinforces the role of renewable energy in Ireland’s transition to a low-carbon economy and underscores the importance of continued investment in wind and solar infrastructure.
