Overview and Timeline

Project Overview

Bord na Móna is proposing to develop a wind farm on Cloncreen bog in eastern Co. Offaly. The proposed wind farm will be known as Cloncreen Wind Farm.

 

Location

The proposed wind farm site is located within the townlands of Esker More, Clongarret, Cloncreen, Ballykilleen, Ballynakill, Ballinrath, Rathvilla or Rathclonbrackan, Ballina and Ballinagar, County Offaly.

The village of Clonbullogue is located approximately 2.0 kilometres southeast of the site.

 

Number of turbines

It is proposed, that the wind farm will consist of 21 turbines. The proposed wind farm will have an estimated installed capacity of approximately 63 Megawatts (MW).

 

Height of turbines

The proposed turbines will have an overall blade tip height of up to 170 metres. Within this size envelope, various configurations of hub height and rotor diameter may be used. The exact make and model of the turbine will be dictated by a competitive tender process post planning and it will not exceed the maximum tip height of 170 metres.

 

Setback distance

The setback distance to the nearest house from a turbine on the proposed layout is in excess of 700m.

 

Substation Location

The application includes two potential substation locations –

Option A - Construction of a 110-kV substation in the eastern section of the site. This substation will connect to the National Grid via an underground cable (approximately 1.7 kilometres in length) running from the substation to the existing 110 kV Cushaling substation at Edenderry Power Plant, located directly east of the proposed wind farm site.

Option B - Construction of a 110-kV substation in the southern section of the site. This substation will connect to the National Grid via a short section of overhead line (less than 0.1km) to the existing 110 kV Thornsberry/Cushaling electricity transmission line, located within the site.

Only one substation and associated grid connection will ultimately be constructed. This is to allow the national grid operator, Eirgrid flexibility when deciding on which is technically preferable from their perspective.
