“One point I would like to raise is a criticism of National Grid's conclusion to their review of costs of laying cables underground compared to installing pylons and overhead lines.

The National Grid stated that the cost of a line of pylons across Anglesey would be £550 million whereas the cost of "undergrounding" would be about £1 billion. They indicate that these costs will be paid by increased electricity bills to all UK customers over time.
If they find it quite reasonable to share the cost of £550 million in this way it also seems reasonable to share less than twice that amount.
The pylons may not run through the Anglesey AoNBs but will be seen by any local person or tourist travelling around the island to visit ancient monuments, beaches, art galleries etc. In general the people of Anglesey are happy to generate power for the whole of the UK and play a part in reducing the use of fossil fuels but they do not deserve to have their home environment damaged

I would find a new line of pylons acceptable if that one line would be sufficient for Wylfa Newydd, Orthios and MORE, future, energy generators.
Then, when that line is completed and functional, the old pylons could be demolished and the people of Anglesey suffer no extra visible damage in the future. ”
