Green Light For British-Norwegian Interconnector

nsn-interconnector

As was the case with earlier cable NorNed, the idea is to use Norway as ‘Europe’s battery pack‘: if there is too much renewable energy generated in the UK, for instance wind energy after 24:00, send it to Norway through the interconnector cable and use the energy to pump up water into mountain basins. When energy is required in Britain, let the water flow back to lower altitudes and generate electricity, that can be send back through the same cable. Overall efficiency still ca. 80%.

Completion date: 2021
Length cable: 730 km
Capacity: 730,000 homes or 1,400 MW (both ways)
Investment: 2 billion euro
