WORK to overhaul part of Scotland’s electricity transmission network is now underway.

As many as 51 electricity pylons from the Stirling Valley will be demolished and replaced with underground cable.

Once the installation of the cable is complete, work on dismantling the pylons, some up to 35m tall, is due to start in late 2018.

SP Energy Networks confirmed that preparatory work on installing ducting for the cables commenced on Monday, September 11, following community consultation.

The new cable will follow a route leaving the network's electricity substation at Springkerse Industrial Estate in Stirling, heading north under the River Forth to Manor Powis and south on a route near the A91, the A905 and the A9 through Plean to Glenbervie.

A spokesperson for the electricity transmission organisation said the cable installation work will be carried out in phases between now and mid 2018 with underground ducting being installed prior to cable sections being pulled through the ducts.

He said: “Removing the pylons in this section of the Stirling was part of the agreed legacy of the installation of the Beauly-Denny line. Residents and visitors alike will notice a significant transformation in the environment.”
