Mainstream was founded in Ireland in 2008 and Dublin is the location of our global headquarters.

With its long coast and high average wind speeds, Ireland is well placed to capitalise on its offshore wind resource.

Mainstream enjoys a strong legacy in Ireland where our people were responsible for developing and building Ireland’s first onshore and offshore wind farms.

Ireland is very much the engine room of our business and we are very proud of our Irish heritage led by our local management team.

Our Irish development track record

Mainstream delivered three onshore wind farms into commercial operation in Ireland.

As part of Mainstream’s Airtricity heritage, we also developed Ireland’s first and only operational offshore wind farm at the Arklow Bank in County Wicklow.

The Arklow Bank wind farm became operational in 2004 and included the world’s first construction of wind turbines rated over 3 MW.

Of the onshore wind farms, Mainstream developed Raragh Wind in County Cavan, Carrickeeny Wind in Country Leitrim, and Knockaneden Wind in County Kerry.

The Carrickenny wind plant was sold to the furniture giant IKEA when it reached commercial operation.
