Frequently Asked Questions

The questions below are addressed comprehensively in the project’s Environmental Impact Statement and Natura Impact Statement. The answers below are shortened versions of the conclusions which are intended to give you a summary of the main conclusions. We would invite you to examine the project in more detail by reading the full text.

Project Overview

Who are the project partners?

Dublin Array Wind Farm is 50% owned by innogy Renewables Ireland and 50% by Saorgus Energy.

Who are they?

Innogy Renewables Ireland is a subsidiary of innogy SE, a leading German energy company, with revenue of around €37 billion (2018), more than 43,000 employees and activities in 16 countries across Europe. With an installed capacity of more than 925 MWs in offshore wind and with over 2100 MWs in onshore wind, innogy is one of the major operators in Europe. innogy also has a pipeline of onshore wind development projects as well as an operational wind farm in Ireland and is currently constructing three battery storage plants.

Saorgus Energy initiated the development of Dublin Array and has also developed over 300MW of onshore wind energy projects in Ireland. It also owns and operates three onshore wind farms.

What stage is the project at?

The project is in the development phase. innogy is leading on the development of the project on behalf of the partnership. We are expecting to submit the application for planning consent in early 2021.

When will the wind farm be constructed?

Subject to achieving a number of consenting milestones, the start of construction is expected in 2024, with a potential two-year construction period.

Will I get to comment on the project?

There is a comprehensive stakeholder and community engagement programme planned for 2020 to ensure that everyone has a chance to talk to us about the project. We will be updating the project website regularly in order that everyone can view key facts, news and development details.

Project Facts

Where exactly will the wind farm be located?

Dublin Array is located on the Kish and Bray Banks, 10km from the coast of Dublin and Wicklow Counties.

How many turbines?

60 – 100 turbines

How tall will they be?

Expected to be up to 250 metres tall to the tip height of the rotor blade and able to produce between 8MW – 15MW of electricity per turbine.

How much electricity will they produce?

We are currently undertaking technical studies that will be influenced by government policy and will be in a range from 600MW – 1GW.

How many houses will that power?

Dublin Array is expected to have the capability of powering between 650,000 and 1,043,000 homes, depending on the final size constructed.

Onshore Activities

Which port will be used during construction?

innogy is investigating the availability of suitable ports both for construction and for operations during the life of the wind farm.

Where will the cable come onshore?
  • A number of landfall sites that are suitable for the power export cable to connect into the grid onshore are under consideration. It is possible that more than one landfall site is required.
  •  

  • In order to establish the likely connection point or points, innogy is currently undertaking surveys into the suitability of sites in conjunction with the grid connection study which is being carried out in consultation with EirGrid.
What needs to be constructed onshore? When will that happen?
  • The wind farm needs to connect into the EirGrid transmission system therefore studies are being carried out, in consultation with EirGrid to establish the likely connection point or points.
  •  

  • It is likely that the connection point will be in an existing EirGrid transmission substation and that either a new substation or additional electrical infrastructure will be required at, or close to the connection point.
  •  

  • The onshore works will comprise the installation of buried cables between landfall and the connection point. No overhead lines are proposed and all the works are required to be designed and built to EirGrid specifications.
  •  

  • The onshore electrical system will require planning permission and will be treated as an integral part of the project. Updated information about the onshore works will be available through the project stakeholder and engagement programme and publicised on the Dublin Array website.
  •  

  • The onshore electrical system needs to be in place before the first generation of the offshore wind farm. This means that construction activity onshore will start early in the programme, with a typical time period being around two years.

Licence Applications

What licence applications have been submitted?

innogy has applied for a Foreshore Licence under the Foreshore Act to undertake further surveys of the seabed and to install buoy mounted equipment to provide data on weather and sea conditions. The information will be used to progress the engineering design and to inform the ongoing environmental assessments required as part of the consent process. Consent of this Foreshore Licence will enable Innogy to undertake further site investigations and data collection; please note this is not the final planning application for the project.

Supply Chain Opportunities

Will businesses be able to provide relevant skills / technical input?

The project could offer a significant economic opportunity for businesses with potential supply chain benefits, infrastructure and associated jobs and contracts as well as training opportunities.

Community Benefits

Will there be any funding available for community projects?

innogy has a long history of supporting the communities in which it operates. As the Dublin Array project progresses we will work with communities to develop our approach to supporting the local area, in line with the requirements of the Governments Renewable Energy Support Scheme.
