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 and the Netherlands, and each year they power five million homes. We’re currently working on another interconnector to link us with Denmark, and by 2030, 90% of the energy imported by our interconnectors will be from zero carbon energy sources.
Our latest interconnector: North Sea Link
North Sea Link (NSL) is our latest interconnector. This high voltage direct current (HVDC) electrical interconnector connects the British electricity network at Blyth in Northumberland with the Norwegian village of Kvilldal, and is able to transport enough clean electricity to power 1.4 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?
