An additional 189 megawatts of wind and solar capacity was connected to the electricity grid during the first two months of this year.
This brought Ireland’s total installed renewable electricity capacity to 8 gigawatts.
Minister for Climate, Energy and the Environment, Darragh O’Brien, described it as a major milestone.
He said it marks a significant step forward in the transition to securing a future with homegrown renewable electricity.
A new peak for wind energy was recorded during February, according to provisional data from EirGrid, and almost 50% of Ireland’s electricity came from renewable sources last month.
Ireland has now doubled wind energy capacity over the past 10 years and receives more electricity from onshore wind farms than any other country in Europe.
The Eirgrid figures confirm that wind energy was the largest source of electricity generation in February, supplying 41% of all electricity consumed.
This was ahead of gas generation which was the source of 37% of electricity.
The solar power sector, which is growing rapidly, is the third highest share of indigenous electricity generation on the grid.
Minister O’Brien welcomed the new data from ESB Networks.
“At this time of global energy uncertainty and rising prices, expanding our homegrown renewable capacity is not only good for the climate – it is essential for delivering long-term energy security and price stability for Irish households and businesses.
“It’s now more important than ever that we reduce Ireland’s exposure to imported fossil fuel price shocks,” he said.
