Undergrounding 132KV Infrastructure

Details & Location

Cairngorms National Park

Stephenson Halliday provided specialists support to this project as a subcontractor to Rambol Environment for SHETL.

The project was one of a suite funded by OfgeM under its VIP funding programme to investigate the opportunities to replace pylons with the greatest visual effect with underground connections. Stephenson Halliday undertook the Landscape & Visual Impact Assessments for LT183 & LT184 VISTA.

The LVIA considered the effects of proposed undergrounding of two sections of double circuit 132kV line within the Cairngorms National Park totalling 12km in length. Whilst the effects of such a change appear beneficial a particular focus of the assessment was on the location and design of the new cable sealing end structures to make the overhead to cable transition. Badly sited these could have offset much of the benefits of pylon removal.
