Ireland Advances Renewable Energy Ambitions with Major Investments

By the Editorial Team · Monday, October 19, 2026

Ireland is accelerating its clean energy transition by expanding renewable capacity, retiring its last coal plant early, and advancing major offshore wind projects to achieve 80% renewable electricity by 2030. This strategy includes significant investments in grid upgrades, energy storage, and cross-border interconnections to enhance energy security and support regional economic growth during the shift away from fossil fuels.

Ireland is advancing its renewable energy goals with ambitious investments aimed at generating 80% of its electricity from renewable sources by 2030. The government reports significant progress in expanding capacity, with onshore wind capacity doubling over the past decade and solar power increasing more than tenfold.

Darragh O’Brien, Minister for Climate, Energy and the Environment and Minister of Transport, highlighted the steady development of clean energy infrastructure across the country. In 2025, the state-owned Electricity Supply Board (ESB) retired the nation’s last coal-fired power plant ahead of schedule, marking a milestone in Ireland’s energy transition. Currently, over 8 gigawatts of renewable capacity are connected to the national grid, providing between 40% and 50% of the country’s electricity needs. However, meeting future demand will require substantially more capacity, with an estimated eightfold increase by 2050.

Looking forward, offshore wind is identified as a critical component of Ireland’s renewable energy strategy. The government is progressing with five major offshore wind projects, most of which are expected to advance through planning and begin construction by 2030. To support this expansion, more than $230 million has been allocated for extensive coastal mapping to identify prime locations for wind farms. O’Brien emphasized the importance of a robust pipeline of projects, combined with strong public funding and private investment.

Ireland has also gained recognition within the European Union for its efforts to integrate renewable energy across scales, particularly in grid management and energy storage. The country ranks third in the EU for large-scale battery storage, with over 800 megawatts commissioned and more than 2 gigawatts under development. Solar microgeneration has grown rapidly, with around 180,000 homes now equipped with rooftop panels that contribute electricity to the grid.

ESB, which operates across power generation, transmission, and retail markets in Ireland, Northern Ireland, and Great Britain, plays a central role in this transition. Paddy Hayes, ESB’s CEO, noted the record levels of investment in clean electricity infrastructure in 2025 and forecast continued growth in capital expenditure in 2026. Alongside ESB, transmission system operator EirGrid has accelerated grid upgrades and resilience efforts, supported by a $21.9 billion grid investment program scheduled through 2030. This program aims to enhance the grid’s capacity to integrate additional renewable sources and support regional development.

Cross-border electricity interconnections form another key pillar of Ireland’s energy strategy. The country currently has two interconnectors with Britain, including the recently commissioned Greenlink cable. Work is underway on a link to continental Europe through the Ireland-France interconnector, expected to begin operation by 2028. Further interconnection opportunities, including additional links to Britain, France, and Spain, are also being explored to enhance energy security and facilitate renewable power exports.

To support regions transitioning away from fossil fuels, the government has committed nearly $200 million through its Just Transition scheme. A notable example is Bord na Móna, a former peat-based energy company in Ireland’s midlands that has shifted focus to renewable generation. The transition has fostered the growth of numerous green technology and clean energy firms in the region, supported by grants and development programs.

Innovation remains a priority for ESB, which collaborates extensively with Irish research institutions and international partners. One of the main challenges ahead is developing cost-effective solutions for long-duration energy storage, critical for managing surplus renewable electricity. Ireland positions itself as a potential leader in addressing this need.

Minister O’Brien underlined the importance of maintaining competitiveness through sound energy policy, emphasizing the role of the clean energy transition in underpinning Ireland’s economic resilience and future growth. Partnerships across the electricity supply chain, both domestic and international, are viewed as essential to achieving the country’s renewable energy objectives.
