Carraig Gheal Wind Farm (Phase 1)

Location: West Argyll, Scotland
Area size: 403,000m²
Product: Biotic Earth
Client: GreenPower (Carraig Gheal) Ltd

Project Background

GreenPower identified the Carraig Gheal wind farm site and then managed the
construction of the wind farm along with the 35km West Loch Awe Timber Haul Route
(WLATHR) and wind farm access. One of the challenges in building Carraig Gheal Wind
Farm was the access to the site and the exposed terrain.
Our Project consisted of the reinstating of the Peatland over a 403,000m 2 area.


We looked at 3 priority areas: Firstly the unstable and areas of bare peat on slopes with
the potential to cause peat erosion. Secondly all roadside verges and batters with steep
≥40 o  slopes across the whole site. Thirdly the ‘restored’ site compound, all areas of bare
peat around the first borrow pit and any steep verges along the site road between the
compound and the first borrow pit. We worked closely with the Senior Environmental
Manager and agreed on a seed mix which included, Browntop Bent, Sheep’s Fescue,
Hard Fescue, Wavy Hairgrass, Slender Creeping Red Fescue, as it has a better binding
capacity than ordinary Red Fescue. It was also imperative that we did not use any
fertilizer but a very low application of lime was discussed to give a the grass seed better
rooting conditions at the reinstated site compound only.


The client had very specific expectations and needed continuity throughout the project.
GreenPower were also very clear that no fertiliser be used in the peat areas and if
necessary a  very low application of lime (eg a maximum of 100kg/ha of ground
limestone) be used. It was vital that lime was not applied (nor lime dust accidentally
blown by wind) onto existing native peatland communities adjacent to the areas of peat
that were being restored, nor should lime be used in the headwaters of any moorland
streams or ditches.  By working closely with the Environmental Management Team we
were able to ensure that their expectations were met and non contaminations of land or
water were achieved.
