Almost 50% of electricity came from renewable sources in February as new peak for wind energy is recorded

New provisional data from EirGrid, the operator and developer of Ireland’s electricity grid, shows that 48% of electricity came from renewable sources in February.¹

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

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 1245 GWh (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 14 February at 5.50pm. This surpasses the previous record set in the same month last year when on 13 February 2025 wind generation reached 3,884 MW.  

In addition to the wind record, Saturday 14 February also saw another new peak electricity demand record for a Saturday. At 6.10pm demand for electricity reached 5408 MW.  

The previous record for a Saturday was set the month before when demand reached 5297 MW on 3 January.  

The overall electricity system demand stood at 3027 GWh in February, compared to 3409 GWh in January.² 

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.”  

About the data   

The data is based on 15-minute SCADA readings (MW). The data referenced above is Ireland-only.   

Data is provisional and unmetered data, based on real-time information.   

¹Average Fuel Mix is a representation of the System Generation fuel mix and net imports across the power system. The “Renewables” category includes wind, solar, hydro and biomass sources. It excludes some non-centrally monitored generation (such as small-scale combined heat and power and microgeneration).  

²System demand represents the electricity production required to meet national electricity consumption, including system losses, but net of generators' requirements.
