Wind generation in Ireland was the second highest on record for a November month, according to Wind Energy Ireland (WEI), which today published its monthly wind energy report.
Wind farms provided 35 per cent of the country’s electricity last month while solar energy and other renewables provided an additional four per cent for a total renewable share of nearly 40 per cent.
The average wholesale price of electricity in November was €122.75 per megawatt-hour (MWh), down 16 per cent from €146.14 per MWh during the same month last year.
Prices on days with the most wind power saw the average cost of a megawatt-hour of electricity fall to €82.55 and more than double to €181.60 on days when we relied almost entirely on imported fossil fuels.
Justin Moran, Director of External Affairs at Wind Energy Ireland, said: “Irish people want cleaner, more affordable, energy and that’s exactly what wind and solar farms deliver.
“It’s positive to see renewables once again supplying nearly 40 per cent of our electricity last month, with wind alone providing more than a third of the country’s power.
“Every time a wind turbine generates power, it helps to lower wholesale electricity prices and, ultimately, consumers’ bills. The more renewable energy we bring onto the system, the more we can displace the most expensive fossil fuels and drive prices down even further.”
County by County generation
The latest figures show that wind power generation in November 2025 totalled around 1,311 gigawatt-hours (GWh), with Kerry once again ranking as Ireland’s highest producing county for wind energy (128 GWh). It was followed by Cork (125 GWh), Offaly (96 GWh) and Galway (91 GWh). Derry edged out Tipperary to secure the final spot in the top five, generating 90 GWh.
Justin Moran added: “Every month we see just how important wind energy is for Ireland and these latest figures show again the key role it plays in powering the country. Counties like Kerry, Cork, Offaly, Galway and Derry are great examples of what we can achieve when we make the most of our natural resources.
“Millions of euros are invested every year by existing wind farms in community benefit funds for local communities to invest in the priorities they choose for their area like sports grounds and play areas – and that figure is set to grow.
“As we keep growing renewable energy across Ireland, we can improve our energy security, cut emissions and help keep prices more stable for households.”
Grid challenges
The launch of WEI’s monthly wind energy report follows the publication of the EU Grid’s Package last week. It contains new measures to upgrade Europe’s electricity grids and enable faster permitting, better planning and increased investment certainty.
Justin Moran concluded: “We welcomed the publication of the EU Grids Package which will have a positive impact on the development of Ireland’s electricity network.
“So far this year alone 14 per cent of wind power has been lost because our existing grid is simply not strong enough to carry all the renewable electricity that our wind farms produce. That means dirtier energy and higher bills for every Irish family and business.
“To deliver more affordable, clean electricity for homes and businesses across Ireland, we need to work together to grow Ireland’s grid capacity. It is vital to have the necessary energy infrastructure in place if we want to grow our renewable energy supply.”
The results of this report are based on EirGrid’s SCADA data compiled by MullanGrid, market data provided by ElectroRoute and solar, other renewables and county-level wind generation data provided by Green Collective.
