I have some recollection that when it was suggested that electricity pylons be taken down and electricity cables be put underground in the Snowdonia national park much was made of the cost and the difficulty. Apparently things are different in Scotland where work to remove electricity pylons and to bury the cables in the Cairngorm National Park has been announced.
The pylons are to go as part of an upgrade to Beauly to Denny electricity line by Scottish and Southern Energy (SSE). Around 33 miles (53 km) of overhead transmission line will come down between Boat of Garten and Cairnmore. Locally some communities have been understandably up in arms about the impact on their local landscape, while others are to benefit from the removal of existing pylons. Amazing what you can achieve if you really want to...especially in Scotland.
