If the Lewis Windfarms ever become a reality, it won't really start until 2014.
The problems lies in transporting the electricity generated in North Lewis and Eishken to the mainland and the Central Belt of Scotland.
There were two options: a subsea cable to the powerstation at Hunterston in Ayrshire; cost about 1 billion pounds. This has been ruled out by the developers of the windfarm (LWP) as not being cost effective. Remains the interconnector (subsea cable to Ullapool) and the overhead transmission line to Beauly, west of Inverness and Denny, near Stirling.
The Beauly to Denny high voltage power cable is already in existence, but in order for it to carry the amount of electricity generated in the Highlands and Islands, it needs larger pylons (twice the current size). Same big pylons also need to go up along the 50 miles between Ullapool and Beauly.
A public inquiry is due to start in the autumn into the transmission line down to Denny, which will take until 2011. A public inquiry into the Lewis Windfarm is also due. The subsea cable then has to be constructed. It was announced on BBC Scotland, Highlands and Islands News this morning that as a result of the delays incurred in the public inquiries, the Lewis Windfarms would not be operational until 2014.
