The world’s longest land and subsea electricity cable, connecting Denmark and the UK, began operating for the first time on 29 December 2023.
The record breaking interconnector extends for 765 km between substations in Lincolnshire and southern Jutland. Initially it will power up 1.6 million British households but by 2025 it should be at full capacity and capable of supplying 2.5 million homes.
The new project cost £1.7 billion and was a joint venture between National Grid and Denmark’s Energinet. As the power will be produced by huge Danish wind turbines, National Grid is anticipating huge benefits for UK consumers, including lower carbon-based power, cheaper fuel bills, and greater security in terms of supply.
The new venture is the latest in a series of interconnectors launched by National Grid, which anticipates that by 2030, “90% of the energy imported through [them] will be from zero carbon energy sources.”
