Irish wind farms provided 41% of the country's electricity in March and at 1,537 GWh of power produced were the country's main source of electricity for the second month in a row, new figures show today.
The figures from Wind Energy Ireland show that Kerry regained its position as Ireland's number one source of wind energy with around 160 GWh of power generated.
It was followed by Cork at 138 GWh, while Offaly rose to third place with 120 GWh. Galway and Tyrone rounded out the top five with 113 GWh and 108 GWh respectively.
Wind Energy Ireland said that rising gas prices drove the average wholesale price of electricity in Ireland last month up by 19% compared to February, but the contribution by Irish wind farms kept prices lower than in March last year.
The average wholesale price in March 2026 was €128.77 per megawatt-hour of electricity. Prices fell to an average of €94.20 on the days with the most wind energy while increased to €179.10 when the country relied on imported fossil fuels.
Wind Energy Ireland said this was the highest average wholesale price since March 2025 when prices averaged at €131.80 and up 19 per cent on February's price of €107.97.
European gas prices jumped at the end of February as tensions rose prior to the US and Israeli attacks on Iran. On 9 April prices were 45% higher than they had been on 27 February, it noted.
Noel Cunniffe, CEO of Wind Energy Ireland, said that at a time when the country was exposed again to the worst effects of a volatile fossil fuel market, Irish wind farms halved the wholesale price of power compared to days when it had to rely almost entirely on imported gas.
"This is the world's second fossil fuel energy crisis in less than five years. The solution is clear, build an Irish electrostate which can rely on our own clean, affordable and secure electricity supplies," he added.
