Renewable energy has registered its highest share in electricity for the month of February, with a 48.1% share.
According to the latest data from state-owned transmission system operator (TSO) EirGrid, the renewables generation also increased by nine percentage points from the previous month, when January registered 39% of electricity from renewable sources.
Wind generation represented the majority of the share with 41.1% or 1,245GWh of wind generation, while solar PV generation rose from 0.8% in January to 1.2% in February, as shown in the chart below.
The remainder of the electricity generation in February came from gas, with 37.7% and from imports via interconnection, with 14.2%.
On top of renewables setting a new highest share of electricity contribution for February, Ireland registered two other records for that month. Wind generation reached a new peak of 3,898 MW, set on 14 February and surpasses the previous record set a year ago, nearly day for day, when on 13 February 2025 wind generation reached 3,884MW.

The other record set in February was for the peak electricity demand on a Saturday, which reached 5,408MW on 14 February. The previous record was set the month before, when demand reached 5297 MW on 3 January.
Despite a new peak demand on a Saturday set last month, the overall electricity system demand decreased month on month from 3,409GWh to 3,027GWh.
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.”
As new peak demand records continue to happen this could drive the Irish grid to a power shortfall in the coming years. Indeed, a recent report from EirGrid warned of a “potentially challenging situation” for the country’s electricity system between 2026 and 2028, with demand outpacing available generation capacity.
