In October 2014, Kerry County Council turned down an application by Stacks Mountain Windfarm Limited to construct a ten turbine windfarm at Ballyhorgan South and East, Irramore, Lissahane and Muckenagh.
The refusal was due to the proposed scale which the council said would create a significant visual intrusion in the local landscape.
The company appealed to An Bord Pleanala the following month and the planning appeals board has now granted permission subject to conditions.
Several protest meetings were held by locals (including two this week), who were primarily concerned about the height of the turbines and almost 260 submissions were made to the local authority.
The group also threatened to sell their homes if planning was granted.
Chair of the North Kerry Wind Turbine Awareness Group Ger Doyle says they will seek a judicial review of the decision and also of another decision to grant permission to a single turbine in Causeway.
