“I believe that National Grid Electricity Transmission are using the presence of one pylon line to justify a second row It is well known that the Secretary of State is discussing the possibility of further reactors at Wylfa in addition to Wylfa Newydd.  

Pylons will be detrimental to views of unspoilt countryside, particularly views from within, and views of, the Area of Outstanding Natural Beauty. There will be a negative impact on the rural landscape.

There is a huge amount of scientific research into the health effects of pylons, and there are quite different views, a bit like the research into tobacco in the 1950’s and 60’s. There are serious concerns, and conflicting views, about the health impacts on people and farm animals.  Better to be safe than sorry and not use pylons and protect the next generations by not running the risk.

Wales is unique in having a Wellbeing of Future Generations Act, and while NGET are not bound by this law, Isle of Anglesey County Council is, and more pylons may leave the authority open to legal challenge.  Pylons are a poor legacy for future generations.
Other technology exists, like underground and subsea, which does not have the negative effects of pylons. ”
