How big is the proposed
The proposed wind park will consist of eight Enercon E-82 turbines on Coillte lands, with a generation capacity of 3 MW each giving an installed capacity of 24 MW. The development will include a small substation also located on Coillte lands. The Carrigadoon project will connect via an underground cable to the grid locally at the Ballydine substation.
What size will the turbines be?
The proposed turbines will have a maximum hub height of 85m, a rotor diameter of 82m and a maximum blade tip height of 126.5m. Turbines have been sized to be appropriate to the area and with due regard to the designation of areas for wind development as set out in the South Tipperary County Development Plan and the Wind Energy Development Guidelines in relation to setback distances, noise and shadow flicker.
How close will the turbines
be to houses?
The draft national guideline for setback distance between turbines and houses is 500 metres. All of the proposed turbine locations are set back by a distance greater than 500m from houses in the locality.
Will there be shadow flicker?
Given the positioning of the turbines relative to the path of the sun and the locations of the nearest dwellings, the potential risk of shadow flicker is low. However, shadow flicker will be modelled under a range of conditions and assumptions to ensure that it remains within the accepted limits as set out in the national guidelines and will not adversely impact upon surrounding dwellings.
Will there be noise?
Advances in turbine technology and design have resulted in reduced noise emissions. The state-ofthe-art 3-blade turbines proposed for this project are direct drive machines. They have no high-speed mechanical components and therefore do not produce mechanical noise.
According to the Wind Energy Development Guidelines, noise is unlikely to be a significant problem where the distance from the nearest turbine to any noise sensitive property is more than 500 metres. Noise levels will be assessed and modelled under a range of conditions and assumptions to ensure that it remains within accepted limits as set out in the national guidelines and will not adversely impact upon surrounding properties.
