Meenadreen, Co. Donegal – Phase 2

Irelands largest on shore wind farm development at Meenadreen in Donegal was developed by the Ronan Renewables group. Phase two of the project saw a record investment of €145m in wind farm development in Ireland.

Phase one of the project saw the development of a 3.6 mega watt project with phase two now set to deliver 95 mega watts per year. Phase two alone consists of 38 Nordex N90 turbines providing over 255 gigawatt hours each year, enough to power 70 thousand homes, and will also involve the construction of a new €11m substation which will contribute to strengthening the electricity network in Donegal.

The development is near the Barnesmore Gap in County Donegal Central to the success of the project and the core skill set of Ronan Renewables was the acquisition of land and careful consultation with local landowners as well as siting to integrate into the national grid.
