Overview and Timeline

Project Overview

Bord na Móna is proposing to develop a wind farm on Derryaroge, Derryadd and Lough Bannow bogs located in south County Longford.  The proposed wind farm will be known as Derryadd Wind Farm.

 

Location

The proposed wind farm site is located within the townlands of Cloonkeel, Ballynakill, Cloonbearla, Cloonbrock, Derryaroge, Mount Davys, Rappareehill, Cloonfore, Cloonfiugh, Barnacor (Ed Rathcline), Grillagh (Moydow By), Derryad (Moydow By), Annaghbeg, Annaghmore, Derryart, Derryoghil, Ards, Corralough, Cloontamore, Derrygeel, Cloontabeg, Kilmakinlan, Derrynaskea, Derryshannoge, Derraghan More, Coolnahinch (Moydow By), Derryglogher, Mosstown (Rathcline By), Corlea and Derraghan Beg.

The development site has an area of approximately 1908 hectares and is located between the towns and villages of Lanesborough (approximately 2km east, as the nearest point), Derraghan, Keenagh and Killashee.

 

Number of turbines

It is proposed, that the wind farm will consist of 24 turbines. The proposed wind farm will have an estimated installed capacity of approximately 96 Megawatts (MW).

 

Height of turbines

The proposed turbines will have an overall blade tip height of up to 185 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 185 metres.

 

Setback distance

The minimum setback distance to the nearest house is 750m.

 

Substation Location

The application includes two potential substation locations -  Option A in Cloonfore townland or Option B in Derraghan More townland - and associated grid connection options. The proposed wind farm connection to the national electricity grid will be either to the existing Lanesborough/Richmond 110kV line via overhead line to Option A, or to the existing Lanesborough/Mullingar 110kV line via an underground cable or overhead line to Option B.
