​Temporary Working Width

To facilitate the construction of underground high voltage electricity cables, a temporary working width is required. The width may vary according to the nature and complexity of the works, however the typical working width for underground cables can be up to 50 metres or more for larger projects. The width will be present during the length of the construction period, with suitable temporary fencing if required, with that temporary fencing removed once the area has been re-instated to the Landowner’s full satisfaction.

Land Drainage

A careful and measured approach is taken to Land Drainage. Landowners are fully consulted and existing drainage schemes are examined before construction begins. Insofar as reasonably possible, existing drainage schemes will be avoided by the construction, but if they cannot be avoided, they will be re-instated to a standard that existed prior to their disturbance to help minimise the impact on continuing farming operations post-construction. A hydrogeological, hydrological and flood risk assessment will have been undertaken as part of the Environmental Impact Assessment along the onshore cable route.


​Access & Maintenance

Access to the underground cables will need to be available in the case of a need to repair, renew or replace the existing infrastructure. In most cases, access to the cables post-construction will only be required when absolutely necessary. Cable marker posts will be placed along the cable route to identify the location of the Cable, and any markers will be positioned to minimise any interference with future agricultural operations, for example, in hedgerows or along field boundaries and adjacent to water courses, highways and footpaths. At locations where sections of cables are joined, manhole covers will be installed for ease of maintenance.
