What's this?What's this?What's this?
Hydro Electric, ScotRail and those Super Pylons

Rumbling on is the planning process for Hydro Electric's proposed Beauly to Denny power line upgrade, with Stirling Council being the most recent to lodge their objection.

The estimated cost of Hydro Electric's plan is 320million, to underground the whole line with such high voltage AC capacity is estimated by HE to cost 12 times as much; put that another way, 3.84billion (3800million).

There would be environmental concerns about digging the huge trenchs, 25m deep required for AC undergrounding of the full proposed capacity, esp along the current proposed route.

If part of the capacity was split between above and below ground, the difficulty and cost of undergrounding would would be reduced. A suggestion which got mentioned briefly in local media from some members of the Highland Council is a fascinating proposal.

The TGV Med line in France opened in 2001 cost just under 2billion for 155miles of 200mph running rail line. By putting half the capacity below ground, and carrying half the capacity on low level overhead rail gantries, we could solve many of the issues surrounding the power line and renewables debate and have the fastest rail line in the UK for less than cost of undergrounding the line entirely. Food for thought surely?
