Whitelee Wind Farm

Client: Scottish Power Renewables (UK) Ltd
Value: £79.2 million
Location: Near Eaglesham, Glasgow

The project comprised the design and construction of the civil and electrical infrastructure works at the largest single onshore wind farm in Europe sited at an altitude of approximately 300m.

Whitelee Wind Farm generates 322MW of energy, sufficient 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. Furthermore, a substation was built at the Ardoch Rig section of the contract and a control building was built at Loch Goin.

During construction, six working borrow pits were used to generate the road and hardstanding materials (2,500,000 cubic metres), and an on-site concrete batching plant was employed.

In addition, approximately 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. A significant depth of peat existed at a number of the turbine foundations (in some locations greater than 9m) which necessitated 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.
