Visual Amenity

As part of the RIIO1 price control, we introduced a new policy for electricity transmission owners (TO) to reduce the visual impact of pre-existing infrastructure in nationally designated areas. The policy applies to infrastructure in the following designated areas: National Parks, Areas of Outstanding Natural Beauty and National Scenic 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.

A TO can propose a new mitigation project to deliver a new enhancing pre-existing infrastructure (EPI) output and request funding for these under its price control.

Before a TO can request funding for new EPI projects, it must have in place a policy in relation to methods of working with stakeholders to select projects in its respective transmission areas.

All projects submitted as part of the EPI output under the RIIO1 price control can be found under this page.
