A brief introduction to the idea of an HVDC ring main for the UK:
Currently we are on the brink of a huge change in the way energy is produced, distributed and used. Called Smart Grid, it's a change as big as the coming of the internet. It will change the sort of car you drive, how and when you use electricity, how electricity is moved from place to place, even the way our country looks. It will make our machines talk to one another and use energy more efficiently and responsibly. It will mean that in 20 years time you'll probably drive an electric car and generate some of your own electricity.
A new technology is being deployed across Europe for distributing bulk electricity called HVDC and it is the method by which electricity is piped from Britain to Europe now. It's also the only sensible 21st century way to get bulk electricity from the north to the south of Britain which is what the pylon ridden 400kV grid does now. So we in Stour Valley Underground are proposing undersea HVDC cables running down the coast taking the power, unseen, linking all of the east coast power generators down into London. Just imagine, if they did this and ran the power lines up the estuaries to the population centers,distributing from there by underground 132kV lines, we could one day rid our landscape of ugly pylons altogether. We want them to start by linking Sizewell to London by undersea HVDC. We believe this is a solution that in time completely rids the countryside of the need for pylons. The future of bulk electricity distribution is undersea, pylon free - HVDC.
In a letter published in the Halstead Gazette over Christmas, David Holland posed the question:
Where is our Bazalgett?
As it's Christmas, where is a saviour for our beautiful landscape? Joseph Bazalgett was the Victorian engineer who fought to create the sewerage system that freed London from the scourge of cholera. Here in East Anglia we need someone of this magnitude with the vision to step outside the myopic National Grid pylon consultation options.
