Mayo has the energy to help you succeed


Mayo offers enormous potential to operators in the renewable energy sector. It offers an abundance of sustainable resources for wind and wave based solutions. These have the potential to fuel not just local or national demand but to meet energy export opportunities too.

Mayo has been actively developing renewable energy sources through:

  • Wind projects both onshore and offshore
  • Atlantic wave and tidal resources
  • Bioenergy   

As the home of Ireland’s first ever wind farm, built by Bord na Móna in 1992, Mayo has extensive skills in the area of alternative energy. Today Mayo’s eight wind farms give a combined output capacity of 81.58MW.



The Sustainable Energy Authority of Ireland (SEAI), Ireland’s national energy authority, is overseeing the Atlantic Marine Energy Test site (AMETS) off the coast of Belmullet, used for testing and demonstrating new wave energy conversion technologies before they are commercialised.

A new wave energy test site, at Blacksod Bay, is being developed in partnership between Mayo County Council and the Irish Wave Energy Development Association and will be open for testing soon.  It will offer realistic testing conditions for wave energy converters product makers.

Other flagship projects include Mayo Renewable Power, a 50mw Combined Heat & Power (CHP) plant currently planned for Killala which will be Ireland’s largest independent biomass power plant.

Through the development of a world class hub for sustainable energy production and export, Mayo is targeting the creation of more than 500 jobs in this field over the next five-to-seven years.

Gas and electricity

Electricity demand from Mayo is distributed from 110kv stations through a 38kv line meeting the needs of businesses.

Through the Grid West €240m electricity infrastructure investment, the electricity transmission operator Eirgrid will deliver a 21st century energy infrastructure to power Co Mayo and other western counties. 

The Grid West project will connect renewable energy resources to the national grid. This will

  • improve Mayo’s security of supply
  • provide a clean green source of energy supply
  • reduce greenhouse gas emissions
  • deliver green jobs to the economy

The Corrib gas field was discovered off the west coast of Mayo in 1996 and represented Ireland’s first commercial offshore find since that at Kinsale Head in 1973. When operational it will provide 60% of Ireland’s gas needs during peak supply having a field life period of between 15 and 20 years.
