Provisional data released by EirGrid, the operator of Ireland's electricity grid, confirms that 48% of the nation's electricity was derived from renewable sources throughout February.

This marks a notable increase from January, where renewables accounted for 39% of the generation mix.

Wind energy remained the primary driver of green power, contributing 41% to the overall fuel mix with a total generation of 1245 GWh. Gas generation represented 37% of electricity use for the month, while 14% was sourced via interconnection imports.

The month was also characterised by new performance milestones. A record for wind-powered electricity was established on Saturday, 14 February, at 5:50 pm, reaching 3,898 MW. This surpassed the previous peak of 3,884 MW set in February 2025.

Furthermore, the same day saw a new demand record for a Saturday, with electricity requirements peaking at 5408 MW at 6:10 pm. This exceeded the prior Saturday record of 5297 MW set on 3 January 2026. Overall system demand for February was 3027 GWh, a decrease from the 3409 GWh recorded 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."

The figures are based on Ireland-only, real-time provisional SCADA readings. The "Renewables" category encompasses wind, solar, hydro, and biomass, though it excludes certain non-centrally monitored sources such as microgeneration.
