The cost of placing new power lines - which would go through North Somerset - underground, cannot be justified.

That's from National Grid  who say burying them would be up to six times more expensive, at up to twenty-four millions pounds per kilometre - compared to no more than four million for overhead cables

The new 37-mile long power line would connect a proposed new nuclear power station at Hinkley Point with a substation in Avonmouth - but campaigners say pylons would ruin the countryside.
