Provisional data from EirGrid, the operator and developer of Ireland’s electricity grid, shows that 48% of electricity came from renewable sources in February.

This compares to the previous month of January when 39% of electricity was generated by renewables.   

Overall fuel mix

Wind energy made up a significant proportion of the renewable energy contributing 41% to last month’s overall fuel mix. Total generation of wind amounted to 1245GWh (Gigawatt hours).  

Meanwhile, gas generation accounted for 37% of all electricity used in February and 14% was imported via interconnection.  

EirGrid data also shows that a new record peak for wind-powered electricity in Ireland was set last month.  

A new record for wind generation of 3,898 MW was reached on Saturday, February 14, at 5.50pm. This surpasses the previous record set in the same month last year when on February 13, 2025 wind generation reached 3,884MW.  

Another new peak electricity demand record

In addition to the wind record, February 14 also saw another new peak electricity demand record for a Saturday. At 6.10pm demand for electricity reached 5,408MW.  

The previous record for a Saturday was set the month before when demand reached 5,297MW on January 3.  

The overall electricity system demand stood at 3,027GWh in February, compared to 3,409GWh in January.

Charlie McGee, EirGrid’s system operational manager, said:  “February saw the biggest contribution of renewable energy on the electricity grid since the same month last year.   

“This is significant as we continue our work making the power system more sustainable for the future and increasing the amount of renewable energy that powers Ireland’s electricity grid.  

“The expected trend of increased demand on the system in the winter months continued through February. Notably for the second month in a row, we again saw a record set for peak demand on a Saturday.”
