Whitelee Wind Farm generates 322MW of energy, enough to meet the needs of 180,000 homes.
The works included a large area of forest clearance, 90km of unsurfaced access roads (66 per cent floating) and 140 turbine bases and hardstandings, together with 986km of power, fibre optic and earthing cables. We also built a substation at the Ardoch Rig section of the contract and a control building at Loch Goin.
During construction, we used six working borrow pits and an on-site concrete batching plant to generate the road and hardstanding materials (2,500,000 cubic metres).
Around a third of the site is built within a Scottish Water reservoir catchment area and a number of turbines were built as close as 150m from the reservoir, which necessitated strict environmental controls. There was a significant depth of peat at a number of the turbine foundations (in some places greater than 9m) which meant we had to implement special measures to construct bases and crane hardstandings in liquid peat conditions, at 28 separate locations.
Whitelee Wind Farm received "Commendations" in the category for "Project" and "Environmental" from the Saltire Society.
