The world’s longest land and subsea interconnector, National Grid’s Viking Link, has started commercial operations. The interconnector, a joint venture between National Grid and Danish System Operator Energinet, has a capacity of 1.4 GW and stretches for 475 miles between the UK and Denmark. It will transport enough electricity for up to 2.5 million UK homes, bringing over £500 million of savings for consumers over the next decade through cheaper imported power from Denmark. Viking Link will increase energy security and contribute to lower carbon emissions. National Grid’s interconnector business is operated by National Grid Ventures.
