Ireland Surpasses 8GW of Renewable Electricity Capacity, Driven by Wind and Solar

Ireland has achieved a significant milestone in its transition to renewable energy, reaching 8 gigawatts (GW) of installed renewable electricity capacity. This achievement, highlighted by Minister for Climate, Energy and the Environment Darragh O’Brien, underscores the nation’s commitment to securing a future powered by homegrown renewable sources.

Renewable Energy Growth in Ireland

The addition of 189 megawatts (MW) of wind and solar capacity in the first two months of 2026 pushed Ireland past the 8GW mark. This progress is particularly notable as renewables surpassed fossil fuels for the first time in Europe in 2025, accounting for 30% of generation compared to 29% for fossil fuels [1].

Wind Energy Leads the Way

Onshore wind remains the dominant force in Ireland’s renewable energy mix, with nearly 5GW of installed capacity. February 2026 saw a new peak for wind energy, with the source supplying 41% of all electricity consumed in the country, exceeding gas generation at 37% [1]. Ireland now boasts more electricity from onshore wind farms than any other country in Europe [4].

Solar Power Gains Momentum

The solar power sector is experiencing rapid growth and is now the third largest source of indigenous electricity generation in Ireland. The Timahoe North Solar Farm in County Kildare, operational since early 2025, delivers 108MWp of renewable energy, enough to power approximately 25,000 homes [2]. Joint ventures between ESB and BnM aim to deliver up to 500MW of solar capacity, supporting national climate targets [2].

Investment in Electricity Infrastructure

The Irish government has approved a landmark €3.5 billion investment in the country’s electricity grid infrastructure between 2026 and 2030, representing the largest single investment in its history [3]. This investment will support key government priorities, including housing, renewable energy and economic competitiveness.

Energy Security and Price Stability

Minister O’Brien emphasized the importance of expanding homegrown renewable capacity in the context of global energy uncertainty and rising prices. He stated that increasing renewable energy sources is essential for delivering long-term energy security and price stability for Irish households and businesses [1]. Reducing Ireland’s reliance on imported fossil fuels is a key objective.
