Interconnectors

Helping us to build a cleaner, greener energy system.

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.
