Prysmian Group, the industry leading cable and systems provider, won a contract worth a record-breaking €800M for the development of a high voltage DC submarine power transmission link between Scotland and England. The project will involve the use of at least 400km of a new Prysmian-developed cable product called Mass Impregnated PPL cables, which utilises new material technology to operate with a record longhaul wiring voltage rating of 600kV. This means that energy losses will be kept to a minimum, resulting in a low CO2 footprint for the supply of Scotland-sourced renewable energy for England and vice-versa (the link will be bidirectional). Commissioning is expected in late 2015.

This technology seems to me to be much more beneficial on a local scale, what if every home had its own battery, then home power generation becomes economically more viable for everyone. If you could show that a system like this could pay for itself in say 5 years then every home would want one. Plus for this to be implemented on a large scale requires massive investment that could be decades away. Share the technology and lets get it in homes by next year. Great ted talk. Jon Senior 0 Reply 1 hour ago: I agree 100%. Localised energy production would also make energy consumers more conscious of their consumption and encourage efforts to reduce it. We can invent and invent all we want, but the fast solution to allowing renewable energies to take centre stage is to reduce the base energy draw. With lower baseline consumption, smaller "always on" generators are required to keep the grid operational. Town and house-l

"At the start of the decade, Network Rail was hit by a wave of cable thefts which approached 1,000 cases a year as the price of scrap copper and other industrial metals soared. New data show that thefts in England and Wales fell below 41,000 in the year 2013-14 - down from 60,000 in the previous 12 months. "In recent years, we have witnessed a huge reduction in the number of incidents of cable theft on the railway," said a Network Rail official. "Disruption caused by the crime has fallen tenfold since its peak in 2010-11, when passengers suffered more than 6,000 hours of delay." Raids on church roofs, to strip copper and lead sheeting - another traditional target for thieves seeking to supply unscrupulous metal dealers - have also subsided with the price of scrap. Other areas affected include telecommunications and power networks, road signs, memorials, libraries, schools and children's playgrounds."

Increased copper use and communications in the home.

Another bad sign for copper demand appeared in the news today. In the UK, Jaguar Land Rover plans to lay off 850 agency workers, mostly IT and engineering staff, at plants in West Midlands and Warwickshire. Staff members at Castle Bromwich, Solihull, Whitley and Gaydon are told that they will lose their jobs by the end of this year. The company claimed the decision as 'responsible and rapid action for the challenging environment it faces'. The company employs 16,000 staff at plants in the region at the moment.
