The Renewable Electricity Support Scheme (RESS) supports delivery of our Climate Action Plan target of meeting 80% of electricity demand from renewable energy sources by 2030.

In 2023, my Department staged our first offshore wind auction under the RESS, known as ORESS 1. Of the six participants in the auction, four were successful and were awarded supports under the RESS. These four projects account for a total capacity of approximately 3.1 GW. None of the four successful projects involves ESB or its subsidiaries.

The two projects unsuccessful in the auction account for another 1.2 GW approximately. These two projects are pursuing an alternative, non-RESS supported route to market and if successful will contribute to our 2030 target of 5GW installed offshore renewable energy capacity.

My Department's next offshore wind auction, known as ORESS Tonn Nua (formerly ORESS 2.1), is expected to take place in the Summer of 2025. This auction will be for a single 900 MW site located off the coast of Waterford in the South Coast DMAP, approved by the Oireachtas in October 2024.

ORESS 1 Successful Projects Capacity MW % ESB ownership
Codling Wind Park 1,300 Nil
Sceirde Rocks Windfarm 450 Nil
Dublin Array 824 Nil
North Irish Sea Array 500 Nil
TOTAL 3,074

I refer the Deputy to the reply provided to Question Number 114 of 22 October 2024, which is summarised below. The position has not altered in the interim.

Details of projects successful in each of the RESS auctions are publicly available on the EirGrid RESS website, and RESS projects which have energised and are eligible for PSO support are listed on the annual PSO Statutory Instrument, the most recent of which can be found on the statute book website here: www.irishstatutebook.ie/eli/2024/si/377/made/en/pdf.

Given the Department's role in overseeing the RESS auctions and potential regular changes in the corporate structure of projects, it is not appropriate or feasible to provide a breakdown of ownership of RESS projects by an individual company. Information submitted at the time of the auction was at a point in time, and ownership (either in part or in its entirety) could have changed in the period since the auction. The ownership, partial ownership and potential ownership of individual projects is submitted to and taken into account by the CRU in the role of determining competition within individual RESS auctions.

The table sets out the aggregate information requested for the four RESS auctions to date:

successful unsuccessful successful MW unsuccessful MW successful GWh unsuccessful GWh
RESS 1 82 26 1,276 283.4 2,236.7 317.24
RESS 2 80 50 1,948 999.8 2,747.9 1,024.5
RESS 3 23 8 646 247.7 934.48 289.09
RESS 4 27 16 1,334 513 2,071 513
