The development of renewable energy, including both offshore and onshore wind, is central to our energy policy.

How wind energy is created

The sun heats the earth unevenly and this creates thermal air currents. In order to achieve equal temperatures around the earth, these air pockets move about as global wind. The energy that travels in the wind can be captured and converted to provide electricity.

Clean and sustainable energy

Wind energy provides a clean, sustainable solution to our energy problems. It can be used as an alternative to fossil fuels in generating electricity, without the direct emission of greenhouse gases. And there will always be wind; it is inexhaustible and renewable.

Wind energy in Ireland

Wind energy is currently the largest contributing resource of renewable energy in Ireland. It is both Ireland’s largest and cheapest renewable electricity resource. In 2020 Wind provided over 86% of Ireland’s renewable electricity and 36% of our total electricity demand. It is the second greatest source of electricity generation in Ireland after natural gas. Ireland is one of the leading countries in its use of wind energy and 2nd place worldwide in 2020, after Denmark.

Statistics on Irish wind energy use

Statistics on wind energy can be found in SEAI’s Energy in Ireland and Renewable Energy in Ireland reports. A detailed annual update on the status of wind energy in Ireland and globally can be found in the IEA Wind Annual report.

Wind farms in Ireland

Planning guidance

The Department of Housing Planning and Local Government (DHPLG) provides planning guidelines and planning exemptions for wind farms and wind turbines. The planning guidelines are being revised. Wind farm design, planning and environmental specialists will help prepare a planning application for large wind turbines. Details of these can be found on the IWEA website.

Grid connection

SEAI has published guides for connecting large and small wind turbines to the electricity system. ESB Networks and Eirgrid provide application forms to apply to connect new wind turbines or wind farms to the electricity network. An electrical engineer will be needed to complete applications to connect large wind turbines.

Buying a wind turbine

Wind turbines that meet the required European and international standards are listed on the SEAI Triple E register for accredited energy efficient equipment. Listed wind turbines qualify for a favourable depreciation regime for corporation tax under the Accelerated Capital Allowances scheme, V.A.T. refunds for the installation of wind turbines for agricultural use by farmers and must be used in all public procurement of wind turbines.

SEAI supports for wind energy research

SEAI supports national wind energy research through its RD&D programme. View details of funded projects and applications for new projects in our RD&D Past Projects section.

Government Supports

The primary support for wind energy is the new Renewable Electricity Support Scheme (RESS) which will deliver Ireland’s target of achieving up to 80% renewable electricity by 2030. To achieve this target set by the 2021 Climate Action Plan, up to 8 GW onshore and 5 GW offshore wind must be connected to the grid by 2030.

The RESS also aims to deliver other policy objectives for renewable energy such as supporting and incentivising communities to engage with and have ownership of renewable projects. The scheme will increase the diversity of renewable technologies, the number and scale of projects receiving support, and will provide opportunities for solar PV, bioenergy and wind all within a cost competitive framework.


The first auction of the new Renewable Electricity Support Scheme was held in 2020 with wind energy projects totalling 479 MW awarded contracts. The auction included measure supporting community acceptance of renewable energy projects, including a mandatory 2EUR.MWh community benefit payment and a reserved auction category for community owned projects.
