Currently in Great Britain, there is a provision of £500 million for UK electricity transmission owners to mitigate the visual impact of existing electricity infrastructure in nationally protected landscapes. The money can only be spent on existing lines through Areas of Outstanding Natural Beauty (AONBs) and National Parks in England and Wales and National Parks and National Scenic Areas in Scotland. For National Grid, the electricity transmission owner in England and Wales, this means considering the visual impact of this existing infrastructure in National Parks and AONBs. National Grid refers to this as the ‘Visual Impact Provision’ or VIP.National Parks and AONBs contain 571 km of electricity transmission lines, which inevitably have adverse impacts on their highly valued landscapes and visual amenity. Mitigating these impacts could involve major engineering and hard choices have to be made about the sections of line that most merit this expenditure. National Grid commissioned landscape professionals to carry out work to help it and its Stakeholder Advisory Group make informed decisions about which lines should be shortlisted for consideration. The project, known as the VIP Landscape and Visual Impact Assessment project, is the subject of this case study.
