Celtic Sea Array

SSE Renewables has applied for a non-exclusive Foreshore Licence from the Irish Government to carry our site investigation works to assess the suitability of 689 sq km of blue sea off the Waterford and Suir Estuary in the Celtic Sea for the potential development of an offshore wind farm.

The site would be capable of generating around 1200MW of renewable energy, contributing significantly to Ireland's target of 7GW of offshore wind energy by 2030.

Situated approximately 25km offshore in the deep waters of the Celtic Sea, the sea depths have the potential to make this site suitable for the deployment of emerging new floating wind technologies.

The site location has been chosen following a phased site selection process which included regional resource and constraints analysis and an assessment of renewable generation capacity requirements. In addition, a preliminary shipping and navigation review was undertaken to ensure navigational risks were better understood should the proposed areas be taken forward for development. These assessments have informed the position, size and shape of each of the proposed area to be surveyed.

As part of the assessment process, SSE Renewables intend carrying out geophysical, geotechnical and environmental surveys of the area of interest. These surveys will enable detailed mapping of shallow geological and seabed character; reconnaissance level mapping of seabed relief and features (i.e. archaeology); greater understanding of wind resource and metocean conditions; and baseline environmental mapping.

To minimise the risk associated with poor winter weather conditions, SSE Renewables plans to carry out most of the proposed site investigation works between April and October annually within the five years following the award of the Foreshore Licence.

The addition of this blue sea development site to its offshore project pipeline demonstrates SSE Renewables’ position as the leading offshore wind energy developer in Ireland as well as in the UK.
