NATIONAL Grid has closed its consultation that allowed people to comment on its policy regarding the undergrounding of electricity lines.

The energy company, which is still to announce the option it has chosen for a 400,000 vault power line planned to cross the North Somerset countryside, launched the exercise in December.

The consultation was carried out as National Grid decided to revise the policies used when deciding whether a line should be put underground or not.

Once all of the comments have been analysed, the company’s final approach will be published later in the summer.

National Grid’s proposals to install a power line from a planned new power station at Hinkley Point C to a substation in Avonmouth caused uproar after it was revealed this would see the installation of 150ft-high pylons.

This led to calls for the cables to be put under the ground or under the Severn Estuary.
