2012 saw the installation of a 48 turbine windfarm on the moors of Roxburghe Estates.
EDF Energy Renewables have now completed the construction of the windfarm which is now at full capacity with 48 turbines generating 144MW. This is sufficient to power 80,000 homes and will result in a carbon saving of 159,000 tonnes/year.
Management of the project by EDF has been exceptionally well delivered and the construction milestones were all achieved. With three major teams responsible for civil works, electrical supply and turbine erection, it has been a huge undertaking to coordinate and manage. The total project cost was in the region of £200m. Some of the headline statistics are interesting:
- 15 miles of access road
- 200 kms of electric cable
- 19,600 m3 of concrete for turbine bases
- 2,610 tonnes of reinforcing steel for turbine bases
- 367,000 tonnes of stone extracted from the quarry on the Little Law (now the Very Little Law!)
- 38 items of ordnance discovered including 3 x 25lb live shells (detonated by bomb disposal unit)
- 230 men on site at peak times
- 382 separate 4½ hr transporter deliveries of turbine components from Rosyth
- £2m injected into local community for local labour, accommodation etc
- Total Co2 saving by replacing traditional generation estimated at 159,000 tonnes/year.
- Total Co2 emissions generated during construction and operation over the life of the windfarm offset in 98 days.
