How many turbines will there be on the Tiree Array site?
The number of turbines has not yet been decided. This will depend on the maximum capacity (MW) of the site for which permission is granted and the maximum power of the turbines to be installed. If 6MW turbines were used, 100 would be required for each 600MW of the project, or 300 for all 1,800MW. A common turbine being installed around the UK in 2010 is a 3.6MW turbine, in which case 500 would be required to generate the same 1,800MW. Similarly if current design developments of 10 MW turbines are successful, they will be considered. 10 MW turbines will be much taller than 3.6MW turbines (see graphic representation, below). The impact ratios on Tiree will be significant irrespective of size of turbine deployed. SPR has yet to provide Tiree with the appropriate montages to illustrate the likely visual impact of any of these options. The trust will post its own indicative montages on this website in due course.
