Republic of ireland wind energy market size in 2026 is estimated at 5.84 gigawatt, growing from 2025 value of 5.25 gigawatt with 2031 projections showing 9.92 gigawatt, growing at 11.17% CAGR over 2026-2031. This report is Segmented by Location (Onshore and Offshore), Turbine Capacity (Less Than 3 MW, 3 To 6 MW, and Above 6 MW), and Application (Utility-Scale, Commercial and Industrial, and Community Projects). The Market Size and Forecasts are Provided in Terms of Installed Capacity (GW).
Republic Of Ireland Wind Energy Market Trends and Insights
Rapid Cost Reductions in Onshore Turbine Technology
Competitive pricing now places onshore wind at EUR 50-60 per MWh, below fossil fuel benchmarks, thanks to average turbine ratings of 5,500 kW and rotor diameters exceeding 180 m. Taller hub heights and extended planning terms of up to 30 years could halve delivered costs, particularly in western counties where wind speeds exceed 7 m/s. These economics strengthen the Ireland wind energy market as the country’s baseload substitute for gas-fired generation.Ireland’s 80%-by-2030 Renewable-Electricity Mandate
The Climate Action Plan aims to achieve 5 GW of offshore and 9 GW of onshore wind by 2030, driving auction volume under the Renewable Electricity Support Scheme and reducing the minimum fossil fuel dispatch from five to four units on the grid. Binding policy certainty accelerates investment decisions and reduces the weighted average cost of capital across the Ireland wind energy market.Planning-Permission Bottlenecks and Judicial Reviews
Only one wind farm gained approval in Q3 2024, while 31 cases were awaiting adjudication, resulting in a backlog equivalent to 18% of the required capacity for 2030. Legal appeals, anti-wind zoning, and resource constraints at An Bord Pleanála extend timelines despite a 2024 Act that introduces statutory deadlines.Other drivers and restraints analyzed in the detailed report include:
- Growing Corporate PPAs & Green-Hydrogen Demand
- AI-Optimised Site Selection Increasing Capacity Factors
- Rising Grid-Connection Charges Under the PR5 Tariff Regime
Segment Analysis
Onshore projects supplied 99.40% of the installed capacity in 2025 and continue to underpin near-term additions, as they rely on mature supply chains and lower capital expenditures. Western and south-western counties record average wind speeds above 8 m/s, sustaining capacity factors that keep the Ireland wind energy market size robust at land-based sites. Yet land availability constraints and growing community resistance moderate future onshore growth. Offshore wind now defines the steepest trajectory, expanding at a 103.8% CAGR through 2031 as 66 projects totaling 70.28 GW advance in the planning queue. Fixed-bottom arrays, such as Codling Wind Park and Arklow Bank Phase 2, target capacity factors above 50%, and floating technology promises to unlock deeper Atlantic resources. Grid-ready ports and bespoke vessel access will determine the pace at which offshore wind energy can reshape the Irish wind energy market share during the forecast horizon.Complete Report Scope:
