The line of pylons was originally planned to help the last Conservative government hit its target of decarbonising electricity by 2035.

The Labour government is now aiming to hit the target by 2030.

Some people living along the route have said it would have a huge impact on the landscape. There are calls for the new power lines to be built underground or at sea.

Conservative leader Kemi Badenoch told the BBC in December she backed the underground option as “the best sustainable option for the future”.

But Tom McGarry from National Grid said: “If it was cheaper and quicker to deliver it off-shore, then that’s what we would be proposing, but it is not. We have to deliver this by 2030.”

Nigel Farage argued the UK should focus on expanding nuclear energy: “That is the future. It gives you continuous base load power twenty-four hours a day.”

A spokesperson for DESNZ added: “Without this infrastructure, we will never deliver clean power for the British people.

“It is important we take people with us and are considering ways to ensure communities who live near new clean energy infrastructure can see the benefits of this.”
