About NISA

Statkraft, Europe’s largest generator of renewable energy, has identified an opportunity to potentially develop an offshore wind farm in an area of the Irish sea, located off the coast of north County Dublin, Meath and Louth. This proposal is known as the North Irish Sea Array or NISA for short.

Harnessing the wind energy in the north Irish sea can deliver real and lasting benefits to Ireland, accelerating our response to climate change and transitioning to a carbon-neutral economy.

We believe that an offshore wind farm in this area has the potential to deliver renewable energy to approximately 500,000 houses and as such it has the capacity to be a project of potential national significance in addressing the very serious impacts associated with climate change.

The NISA project is currently in the earliest stages of development. This offers us a chance to consult with the local communities and wider stakeholders, during the design stage, in order to develop the most suitable and appropriate proposals possible. 

We believe that this project can harness the power of the wind whilst achieving a balance in terms of our marine area, coastline and seascapes.

There will be many aspects of this proposal to be considered over the coming year and possibly longer. It will be 2022 before any planning application is brought forward for consideration. In the intervening time, we will endeavour to continue as we are starting out, by providing the information available and working to consider all views on how this proposal could be best tailored to enable it to play a very positive role in our energy future.

Statkraft has a long history of involvement in the development of renewable energy projects and endeavours to work with all parties to ensure that projects are designed and developed in the most suitable and appropriate way.

Survey Effort Overview

With geophysical surveys due to commence shortly, NISA has reached a critical milestone in its development. The surveys planned will provide information which will allow the project to develop a detailed understanding of the sea bed conditions which will inform the design of the project. These surveys are due to start towards the end of May 2022 and will continue throughout June. For more information, please see Marine Notice No. 27 of 2022 through the button below.

Surveys will be subject to weather conditions and a vessel called the Mercator will use various technologies to analyse the sea-bed such as multibeam echosounders, side scan sonars, magnetometers and sub-bottom profiling. The data will be used to inform indicative turbine location and potential cable corridors. The NISA project was granted a Foreshore Licence earlier this year which allows it to gather information and undertake preliminary site investigations to understand the conditions.

Statkraft has engaged an extremely experienced survey contractor to carry out these surveys, particularly in terms of carrying out surveys whilst sharing this marine space with the existing fishing operations. Throughout the surveys, Statkraft will continue to engage all those interested in the local and surrounding communities in the area. This includes extensive engagement with local fishing groups in Howth, Clogherhead, Skerries, Balbriggan, and surrounding areas.

From the earliest stages of this project, Statkraft has been committed to developing a project which would deliver successful coexistence with fisheries and support a sustainable local fishing community. During these surveys it will continue to work proactively towards this goal and promote continued sustainable fishing in the area.
