Tonn Nua offshore wind project, Ireland
Name of the Project
Tonn Nua offshore wind project.
Location
The Tonn Nua site spans 306 km2, off the coast of County Waterford, in Ireland.
Project Owner/s
A joint venture between ESB and Ørsted.
Project Description
Ireland’s contract for difference (CfD) is to support the development of a 900 MW fixed-bottom offshore wind farm at the site.
The project has been awarded under Ireland’s contract for difference mechanism – a primarily government-backed, auction-based scheme under the country’s Renewable Electricity Support Scheme, designed to provide long-term price stability for renewable-energy generators.
It fixes the price (strike price) for green electricity, ensuring revenue certainty for developers and mitigating costs for consumers when market prices are high. Ireland’s transmission system operator EirGrid will build the transmission assets – offshore and onshore substations and export cables.
Potential Job Creation

Capital Expenditure
