The preferred mitigation option involves the replacement of the existing section of overhead line with underground cabling.
We have considered a range options for an underground cable route. Findings from our environmental and technical studies and feedback from stakeholders and the local community have played a vital role in selecting a preferred route.
The Peak District National Park project will replace a 2km section of overhead line east of the Woodhead Tunnel near Dunford Bridge with an underground solution, permanently removing seven pylons and a sealing end compound from the landscape. The preferred route for the new cable will run alongside the Trans Pennine Trail to the south of the River Don to join existing cables in the Woodhead Tunnel. As part of the project, the Trans Pennine Trail will need to be temporarily diverted for approximately two years to allow for construction work.
Construction of a new sealing end compound and associated replacement terminal pylon is required at Wogden Foot local wildlife site to connect the cable to the remaining existing overhead line. At the western end where the 12 cables which we will be burying join up with the cables running through the Woodhead Tunnel, we will need to construct a cable jointing building. This will be built on National Grid land and we are speaking with the National Park Authority to ensure that the building we create is in keeping with the character of other buildings in Dunford Bridge.
During 2016, we carried out some ground investigation works and a number of environmental surveys north and south of the River Don near Dunford Bridge to identify any environmental issues and develop the engineering plans for an underground route option.

The current indicative programme is that, subject to all necessary approvals and consents, on site works will commence in spring 2019 and take approximately two years to complete.
