My Department publishes an indicative schedule of future auctions under the Renewable Electricity Support Scheme (RESS). The indicative volumes are based on estimated renewable generation volumes required to meet Ireland’s 2030 target of 80% renewable electricity by 2030.
The latest schedule, which is due to be updated shortly, is published on my Department's website here:

In relation to offshore wind auctions, the North Seas Energy Cooperation, of which Ireland is a member, published in November 2023 a ‘tender tool’ showing indicative auction schedules for each member state out to 2030. Details of Ireland’s anticipated offshore wind auctions can be seen through the tender tool here:
