European Supergrid Submarine Cables – Inventory & Plans

An essential part of the solution to Europe’s energy problems is the European Supergrid. It means that all European countries will be interconnected to even out demand and supply patterns. Most countries in continental Europe are already strongly interconnected. A missing link though are connections to the country that could serve as ‘Europe’s battery pack‘: Norway.

The first subsea connection was between Norway and The Netherlands: NorNed. Others followed like BritNed.

The Germans also have plans to link Germany with Norway: NorGer and NORD.LINK. NorGer plans got concrete by December 2012.

Siemens to increase power transmission capacity between England[source]
Siemens has won a 1.1 billion euro contract to connect England and Scotland (420 km, 2200 megawatts bi-directional, late 2015).

SSE’S Norway Interconnector Project. Meanwhile, SSE has withdrawn from the project. NorthConnect‘s other partners, Sweden’s Vattenfall and Norwegian companies E-CO Energi, Agder Energi and Lyse, said it would not affect their plans. NorthConnect has the support of Alex Salmond, the First Minister of Scotland, the man pushing for Scottish independence.

Iceland is considering building the world’s longest subsea power cable by around 2020 to take advantage of its abundant geothermal energy to supply Britain with green power, the head of the state-run electricity producer said. “We can serve as a green battery for the U.K.,” Hordur Arnarson, the chief executive of Landsvirkjun said in an interview… Landsvirkjun expects to make a final investment decision on the 1,000 kilometre subsea cable by 2015-2016… McKinsey & Co. estimates it (Iceland) is harnessing only 20 to 25 per cent of its hydro and geothermal energy potential… Mr. Arnarson declined to cite a figure for the costs of construction, which would take five years and would entail laying cable 3,000 metres underwater in some areas. The longest subsea cable currently in operation is the 580-kilometre NorNed link from Norway to the Netherlands, which was completed in 2008 and cost €600-million ($784-million U.S.).

Israel-Cyprus-Crete-Greece
Now even Israel wants to get connected to Europe (Greece), to start with Cyprus.
The cable’s total length measures 870km (540 miles) and its depth is over 2,000 meters (656 feet). Between Israel and Cyprus, the cable will be 270km long. Electricity will flow in both directions at a capacity of up to 2,000MW. Another cable will connect Cyprus and Crete which forms part of the Greek electricity grid. As a result, Israel will be connected to the European electricity grid.
