Wind power generates a third of electricity required so far this year

During May, wind farms produced 693GWh of electricity, around 22% of demand. 

Power generated from wind farms supplied 33% of the country’s electricity during the first five months of the year, new data from Wind Energy Ireland shows.

During May, wind farms produced 693GWh of electricity, around 22% of demand, which was up slightly when compared to May of last year. Kerry saw the highest wind energy output, with Cork and Galway in second and third place respectively.

Noel Cunniffe, chief executive of Wind Energy Ireland, said the more wind farms we can build, the “less we are relying on imported fossil fuels, meaning lower carbon emissions and lower energy bills”.

Wind Energy Ireland is the representative association of companies working in the wind energy sector.

According to EirGrid, solar power generation reached its highest recorded figure on the national electricity grid in May while almost a third of electricity came from renewable sources last month.

Of the 32.5% of electricity generated from renewables in May, the majority came from wind while 6.5% came from solar, and the remainder of renewable generation came from other sources, including hydro and biomass.

EirGrid is responsible for operating Ireland’s electricity grid and market. Overall, electricity system demand was 2,671 GWh for May 2025, similar to 2,679 GWh in May 2024.
