Determination on SHE Transmission’s proposal for reducing visual amenity impacts in the Cairngorms National Park

Decision

As part of the RIIO-T1 price control, Ofgem introduced a new policy for electricity transmission owners (TOs) to reduce the visual impact of pre-existing infrastructure in nationally designated areas. The expenditure cap for all mitigation projects that come forward under the scheme during the RIIO-T1 price control is £500 million (2009/10 prices) in total.

On 28 February 2019, we consulted on our proposed efficient costs for Scottish Hydro Electric Transmission’s (SHE Transmission) Cairngorms National Park mitigation project. A non-confidential summary of SHE Transmission’s submission was published alongside our consultation.

This letter explains our determination on SHE Transmission’s proposal for reducing visual amenity impacts in the Cairngorms National Park under RIIO-T1 provisions for the mitigation of pre-existing infrastructure.

Alongside this letter, we’re publishing a notice under Part C of Special Condition 6G of the Electricity Transmission Licence for modifications to SHE Transmission’s electricity transmission licence and allowed revenue to implement our decision. Details of the changes are set out in the notice.
