Renewables provided just over 40% of the country's electricity in October, new data shows.
According to grid operator EirGrid, the majority of renewable electricity generated last month came from wind farms at almost 35%.
Total generation from wind energy amounted to 1,003 GWh over the month.
Overall, renewables including wind, solar and hydropower provided 40.4% of electricity in October.
52 GWh of electricity came from grid-scale solar last month, down from the highs of the summer months but well ahead of the 32 GWh of solar registered last October. Grid-scale solar accounted for 1.8% of electricity in October.
The data shows that gas generation accounted for 42.5% of all electricity used in October, with just over 12% being imported via interconnection, 3.7% coming from coal, and the remaining 1% from other sources.
"We had over 1,000 Gigawatt hours of wind on the system in October, which is the first time this has passed the 1,000 GWh mark since March of this year as the windy weather returns," said Diarmaid Gillespie, Director of System Operations at EirGrid.
"Whereas grid-scale solar is down from the highs of the summer months, as recently as 2022 we had no solar at all on the transmission system.
"So the fact that this form of generation is making a contribution to the electricity being used around the country demonstrates the progress that is being made in this area, and the benefits of being able to rely on a range of sources to maximise the availability of renewable generation in all seasons," he added.
EirGrid is responsible for leading Ireland's transition to a low carbon future so that 80% of electricity can come from renewables by 2030, as set out in Government targets.
Currently the electricity grid can accommodate up to 75% of electricity from renewable sources at any one time.
