Rollout of overseas power link leaves UK reliant on neighbours for energy

From a remote field in Lincolnshire, teams of engineers are installing a high-voltage cable to carry electricity 765km to and from Denmark.

The world’s longest “interconnector”, the Viking Link will pass under the North Sea and four nations’ waters, dodging unexploded bombs and pagan burial sites along the way. It will eventually have the capacity to supply energy to 1.4mn homes in the UK, or 2mn in Denmark where average consumption is lower.
