Wind was the biggest contributor to Ireland’s electricity mix in April, providing 38% of total generation.

According to EirGrid, renewable sources supplied 48% of the country’s electricity during the month, with grid-scale solar accounting for 6%.

The operator said this was the third month in a row in which renewables met close to half of overall electricity demand.

Wind generation totalled 1,078GWh in April, while grid-scale solar produced 163GWh.

EirGrid said this was up from 761GWh of wind and 119GWh of solar recorded in April 2025.

Gas-fired generation made up 35% of electricity production, while 16% was imported through interconnection.

Overall electricity demand reached 2,865GWh in April, compared with 3,142GWh in March.

EirGrid said it can now accommodate up to 75% of electricity generation from variable renewable sources at any given time and is aiming to raise this to 95%.

April also marked a new solar generation record, with output surpassing 1GW for the first time and peaking at 1,133MW.

“It’s encouraging to see this was the third consecutive month where renewables generated almost half of Ireland’s electricity,” said Diarmaid Gillespie.

“Wind remains the largest contributor, while the growth of solar in Ireland’s energy mix is particularly notable as we move into the summer months.”
