Tonn Nua (lit. 'New Wave' in Irish) is a proposed 900 MW offshore wind farm located off the coast of County Waterford in Ireland. The project will be developed by a joint venture between the Irish state-owned ESB Group, and the Danish multinational energy company Ørsted, which is the largest offshore wind farm developer in the world.[1]
If developed, the wind farm will generate enough electricity to power the equivalent of around 800,000 Irish homes.[2] It is expected to enter operation in the 2030s.[3]
Background
In July 2023, the Department of Climate, Energy and the Environment (DCEE) selected the south coast as the location of the first Designated Maritime Area Plan (DMAP) Proposal.[4][5]
The South Coast Designated Maritime Area Plan (SC-DMAP) approved in October 2024 identified four 'Maritime Areas' off the coast of Waterford for the development of offshore renewable energy (ORE)[6][7]; Maritime Area A, or Tonn Nua, was selected as the site for Ireland’s second offshore auction under the Offshore Renewable Electricity Support Scheme (ORESS).[8][9] With the announcement of the provisional results of the auction on 26 November 2025, Helvick Head Offshore Wind DAC, a consortium of ESB and Ørsted, was awarded the rights to develop the site;[10][11][12] this was confirmed by the final result of the auction on 9 December.[13]
