Observing the world of renewable energy and sustainable living

NorNed

There can only be one energy strategy for Europe in a resource depleted future: the European supergrid, a pan-European infrastructure, consisting of renewable energy generation, mainly based on wind and solar and large scale hydro storage to filter out intermittent energy supply from said sources. NorNed was a major step towards that integrated renewable European energy future. After 2020 slowly declining fossil fuel supplies from Russia need to be gradually replaced by this renewable infrastructure, probably combined with severe energy saving measures as well as rationing.

Wikipedia: NorNed is a 580-kilometre (360 mi) long HVDC submarine power cable between Feda in Norway and the seaport of Eemshaven in the Netherlands, which interconnects both countries’ electricity grids. It is the longest submarine power cable in the world.[2] Budgeted at €550 million, and completed at a cost of €600m,[3] the NorNed cable is a bipolar HVDC link with a voltage of ±450 kV and a capacity of 700 MW. NorNed is a joint project of the Norwegian transmission system operator Statnett and its Dutch counterpart TenneT… After two months of operation, the cable generated revenues of approximately € 50 million, meaning that in two months’ time, 8% of the total costs of the cable have been recovered. In the business case drawn up for the NorNed cable, annual revenues were estimated at €64 million. NorNed has been included in European Market Coupling Company operations as of 12 January 2011.

Translated Dutch wikipedia: the cable is a big success; in 2008 (cable in use for merely eight months) 3000 GWh were imported by the Netherlands and 330 GWh were exported. The cable is used to import cheap clean hydro electricity during the day from Norway. During the night cheap Dutch electricity is exported to spare reserves in the Norwegian hydro bassins or even to pump up water into the bassins. In this way the lakes are used to store energy that can be easily be reovered for times of peak demand.

NorNed, this is it: 700 MW through 35 mm copper core.
Total weight cable: 57,000 ton or 100 kg per meter.
