NISA Offshore Wind Farm

The North Irish Sea Array (NISA) is an offshore wind energy project with the potential to power up to 500,000 Irish homes with clean renewable energy.

Proposed off the coast of Dublin, Meath and Louth the project has the opportunity to deliver a secure energy future for Ireland, reduce our carbon emissions and support transformational change for communities.

2026 Updates

Following receipt of the Request for Further Informaiton (RFI) and extensive stakeholder meetings, consideration was given to understanding how a refined offshore design could address concerns within the RFI and further mitigate potential environmental effects from the proposed development.  This achievement underscores NISA’s commitment to innovation in site characterisation, efficient development processes, and environmental responsibility.  

 

NISA has now submitted the RFI to An Coimisiún Pleanála with all detail avaiable to view here. 

 

Key refinements include: 

  • Removal of monopile foundations for both Wind Turbine Generators (WTGs) and Offshore Substation Platform
  • Refinement of foundation installation methodology to jackets with suction buckets, a low underwater noise WTG installation
  • Refinement of WTG layouts for Project Option 1 and 2 to address navigational safety concerns and reduce the overall infrastructure footprint within the NWIS SPA

Implications of refinements include:    

  • Significantly reduced underwater noise during construction  
  • Improved search and rescue capabilities  
  • Increased distance from Rockabill  
  • Reduced density of turbines in the southeast area of the Maritime Area of Consent (MAC) where there is higher density in vessel traffic  
  • Reduction in footprint of the turbines within the array area, reducing overlap with foraging grounds for bird species protected by the North West Irish Sea SPA 

 

Working With Local Communities

The NISA team has been working with communities since 2021, sharing project updates as the design evolved and ensuring we captured views and feedback.

Engagement is not simply about providing information. We want the community to engage proactively with us too.

NISA is a project that is ultimately about delivering for people and the future and we believe that everyone should have an opportunity to have an input into how the project is delivered.
