‘Undergrounding’ electrical transmission cables
There are 4,500 miles of overhead electricity transmission lines in England and Wales. This contrasts with just over 900 miles of underground cables. ‘Undergrounding’, the replacement of overhead cables with underground cables, is used in limited circumstances, such as in nationally designated landscapes. There have been calls for an increase in undergrounding. However, the government has pointed to several issues, including the higher cost of underground cables.
