Energia Renewables completes seabed surveys for North Celtic Sea


Irish energy provider Energia Renewables has reached a key milestone in the development of the
North Celtic Sea offshore wind farm, as seabed surveys off the coast of Waterford have been completed.

Following the award of a Foreshore Licence in September 2021, the geophysical and geotechnical surveys started in April 2022 and were completed in October. The surveys measured important information on seabed conditions including water depth, sediment type and habitat distribution. The information from the surveys will inform the continued project design including the number, size and optimum placement of the wind turbines.


Subject to statutory approvals, construction of Energia Renewables’ North Celtic Sea project could commence in 2026. The project is expected to generate electricity for over 500,000 Irish homes and businesses.

Energia Offshore Renewables Manager, Eoin McPartland said, “We’re at an exciting stage of the North Celtic Sea project off the coast of Waterford. The completion of our seabed surveys is an important milestone as we continue our steady progress to realise the potential of this development for offshore renewable energy in Ireland.

“In an increasingly competitive global market for surveys of this type, with waiting times of up to two years for vessels to survey during available weather windows, it’s very significant that these surveys are now complete so that we can contribute to the achievement of Ireland’s 2030 ambitions. We will now progress to more detailed design and consultation ahead of the establishment of the Maritime Area Regulatory Authority (MARA) and will then proceed with a formal planning application in due course.

“We’re very grateful to the fishing community for their engagement and discussions with us, which helped us to successfully complete these surveys, and to everyone who has taken part in our consultation processes and our public information clinics to date. We will continue to consult with fishing and local communities and will provide regular updates on our North Celtic Sea project on an ongoing basis.

“We are currently progressing further studies to identify potential grid connection options and suitable locations for construction and operations facilities. This includes ecological surveys to determine the ecology of the seabed and surrounding waters.”


In addition to the North Celtic Sea project, Energia Renewables is also progressing the South Irish Sea offshore project off the coasts of Wexford and Wicklow. The seabed surveys for this project are nearing completion.
