AMEC HAS begun construction at the biggest onshore wind farm in the UK under a £24M contract awarded by CRE Energy.
The contract for the 1,860ha Black Law site in central Scotland covers construction of anemometer masts, new and upgraded access tracks and a substation.
Gravity foundations and bolts will secure the 2.3MW turbines and the 300m3 bases will be fixed to each of the steel masts by 120, 2m long bolts.
Ground investigations will involve boreholes to 30m through the peat and into the underlying glacial till.These will be put down at each of the 42 bases before the concrete pours begin.
The first of the foundations will be finished this month.
Aggregate from a nearby coal mine will be used for the project and the abandoned opencast works will be restored when the project is completed.
The wind farm will begin producing electricity in April 2005 and will be extended by a further 20 turbines once additional planning conditions are satisfied.
It will help the UK meet its commitment under the Kyoto Protocol to reduce carbon dioxide emissions by 20% by 2010.
