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.

EcoSea, the Chile based manufacturer of copper mesh cages for use in aquaculture systems, announced that it intends to enter the Northern European market beginning with Norway and Scotland. The company expects to install its first 40 cages in Norway by 2013, generating revenues of US$15M. EcoSea is also dealing with Marine Harvest, a global leader in fish farming, who have agreed to install a fish farming complex using copper mesh cages in Scotland. To date, EcoSea has used 1000t of copper, however, its accumulated total use of copeer is expected to rise to 5,000t in the coming years.

"Offences involving copper theft in London shot up 85 percent last year to 1,516 from 816 in 2009, data from New Scotland Yard showed on Friday."

Figure 8.2.2.1 illustrates the lengths of subsea cable that may be required year by year. It is based on expected device spacings, farm layouts and likely distances from offshore substaons to shore. The final lengths required will depend on exact site layouts and separaon distances between devices as well as the method of connecon between devices, which could have dedicated connecons to the transformer or be chained together. The chart has the same profile as that of the number of devices installed, but offset as cables are purchased in advance of installaon. Export cables installed as part of a project's inial phase may be specified with sufficient capacity to accommodate later phases as well.

It's been a long, challenging endeavor, but there are signs that the economic ecosystem built up around wave and tidal power generation is at long last gathering enough momentum to make the jump from R&D-driven to full-fledged commercial industry. Scotland, with its long stretches of west-facing coastlines, North Atlantic latitude and longstanding tradition of maritime engineering and commerce, is now at the leading edge of change when it comes to fostering development of marine renewables. Wavegen's Limpet 500 system has been pumping electricity from the western Scottish Isle of Islay shoreline since 2000 while the company and project developer npower renewables have continued to move forward with plans to develop the Siadar Wave Energy Project, potentially the first under the Scottish government's Marine Supply Obligation program. Marine Current Turbines is getting ready to flip the switch and fully commission a grid-connected 1.2-megawatt (MW) Seagen tidal turbine-based system in Northern Ireland's Strangford Narrow, while elsewhere in the EU, project developers and the marine renewables community await the much-anticipated commissioning of Pelamis's novel, serpent-like wave power system off the northern Portuguese coast.
