Crossing more than 700km of seabed between the Isle of Grain, south-east England, and Fedderwarden, north-west Germany, the planned NeuConnect electricity cable will enable the two G7 economies to trade electricity directly for the first time.
The £2.4bn project is one of several long-distance, cross-border cables, known as interconnectors, being developed around the world as the shift away from fossil fuels fosters a new era of international energy trading.
