Market Overview
Ireland's wind energy sector represents one of the most mature renewable energy segments in the country, with total installed capacity reaching 4.925 GW as of 2025. The sector contributes 11.46 TWh of electricity to the national grid, meeting 35.1% of the country's overall electricity demand. The market is valued at approximately $6.5 billion in 2025 and continues to expand as Ireland advances toward its legally binding climate and renewable energy targets under EU frameworks.
- •Installed wind capacity stands at 4.925 GW with annual generation of 11.46 TWh
- •Wind energy satisfies 35.1% of Ireland's national electricity demand
- •Market valued at approximately $6.5 billion in 2025
Growth Drivers
Ireland's wind energy expansion is primarily propelled by the country's commitment to EU climate targets and renewable energy mandates. The Irish government's policy framework, including successive Climate Action Plans, provides regulatory certainty and financial support mechanisms for further wind deployment. Ireland's exceptional wind resource, particularly along its Atlantic coastline, offers some of the highest wind yields in Europe, making projects economically attractive.
- •EU climate and renewable energy mandates requiring significant decarbonization by 2030
- •Excellent wind resource with consistently high wind speeds along the Atlantic coast
- •Policy support through Climate Action Plans and renewable electricity support schemes
Segmentation and Regional Analysis
Ireland's wind energy market comprises both onshore and offshore segments, with onshore wind currently representing the dominant share of installed capacity. The majority of wind farms are concentrated in the western and southern regions, where wind speeds are consistently higher. Counties including Clare, Mayo, Cork, and Donegal host the largest concentrations of wind assets.
- •Onshore wind dominates current capacity; offshore represents emerging growth opportunity
- •Western and southern regions host highest concentration of wind farms due to superior wind resources
- •Coastal areas particularly favorable for future offshore wind development
Trends and Outlook
What are the recent trends and outlook?
Wind energy is expected to remain Ireland's primary renewable electricity source through the coming decade, with the offshore segment representing a major growth frontier. Grid infrastructure improvements and increased interconnector capacity will be critical to support higher penetration levels. Wind curtailment reached 10.1% of available wind energy in 2025, up from 8.9% in 2023, highlighting the need for continued grid investment and storage solutions.
- •Offshore wind auctions and marine planning frameworks expected to unlock substantial new capacity
- •Grid investment and storage deployment needed to address rising curtailment rates
- •Market projected to maintain 7.01% CAGR through 2033
