Wind generation is supported mainly through the legacy renewable energy feed-in tariff, REFIT, schemes and the renewable electricity support scheme, RESS, and funded also through public service obligations, PSO. These supports are a critical enabler of the investment needed to underpin a renewables-led energy system.

Over the 2025-26 PSO year, the Commission for Regulation of Utilities reports that over 3.3 GW of wind capacity was supported by the PSO. Of this, more than 2.9 GW was supported under the REFIT and over 0.4 GW under the RESS, with over 1 GW of solar also supported under the RESS. In addition to that capacity, some wind farms operate without PSO support, selling directly into the market or under private power-purchase agreements. Taking all of them into account, the total installed wind generation capacity has reached over 5 GW. Industry sources indicate that approximately 2.5 GW of onshore wind capacity has secured planning permission but is not yet built and that another approximate 1.5 GW of projects are seeking planning permission or are the subject of judicial review.

The Government remains committed to the development of 5 GW of offshore wind capacity with projects in construction by 2030 and energised as soon as feasible thereafter. Projects from the ORESS-1, accounting for 3 GW, are progressing through the planning process within An Comisiún Pleanála. Separately, the 900 MW Tonn Nua site within the south coast DMAP will go to auction this autumn.

Delivering on this capacity, combined with our 5 GW of existing installed wind capacity, will bring us closer to achieving our national ambition of 9 GW of onshore wind and 5 GW of offshore wind in the very near future.
