About interconnectors
Interconnectors are high voltage cables that are used to connect the electricity systems of neighbouring countries. They allow us to trade excess power, such as renewable energy created by the sun, wind and water, between different countries.
We already have interconnectors linking us to France, Belgium, Norway, Denmark and the Netherlands, and each year they power millions of homes. By 2030, 90% of the energy imported by our interconnectors will be from zero carbon energy sources.
Our latest interconnector: Viking Link
Viking Link is a high voltage direct current (HVDC) electrical interconnector that connects the British electricity network to Denmark. The £1.7 billion link stretches for 475 miles between the two countries and at full capacity can transport enough electricity to power up to 2.5 million UK homes.

The next generation interconnector
Interconnectors already provide a way to share electricity between countries safely and reliably. But what if they could do much more than that? What if interconnectors could become an offshore connection hub for green energy?
