Earlier today, the Department of the Environment, Climate and Energy (DCEE) published the provisional results of the Tonn Nua offshore wind auction, Ireland's second offshore wind auction under the offshore renewable electricity support scheme (ORESS).

Background

This auction to procure 900MW of offshore wind has taken place under the Government's new plan-led approach to offshore renewable generation and will significantly contribute to Ireland meeting its national and EU climate targets. The plan-led approach involves the Government identifying appropriate sites for offshore wind farms and places responsibility on EirGrid to roll out the required offshore electricity transmission infrastructure.
