Ten turbines on a Sligo mountain form the biggest wind farm in Ireland.
The turbines each stand sixty metres high and span forty metres wide on King's Mountain.
They turn twenty four hours a day to take advantage of the Atlantic winds.
The wind farm was officially switched on by Airtricity CEO Eddie O'Connor. The company say that Ireland can and must build up its wind power. A week earlier the electricity regulator, EirGrid, said that no more wind farms could be connected to the national grid this year.
Eddie O'Connor believes that EirGrid must prove why Ireland can not go to three thousand megawatts in Ireland, which is what they have in Denmark, a country similar in size to Ireland.
The Kings Mountain farm will supply the national grid with enough green energy to power sixteen thousand homes. Eddie O'Connor is critical of the ESB attitude towards wind farms and says there has to be greater investment in the national grid to accept more wind power and reduce Ireland's dependence on imported fossil fuels.
Sligo people have been invited to an open day on the site to see the wind farm for themselves.
In the new year, Airtricity hopes to begin work on a wind farm five times the size of the Sligo farm in County Donegal.
