Britain and Norway are building the longest undersea power cable

Great Britain and Norway have agreed to connect their energy networks through the longest submarine interconnector of its kind in the world, which will provide enough electricity for almost 750.000 British households, reports the British newspaper "The Guardian".

The largest British energy supplier, National Grid, and the Norwegian company Statnet have signed an ownership agreement, which marks the start of construction of the 730-kilometer interconnector.

The two-way electric cable, whose construction worth two billion euros will be financed by the governments of the two countries, will have a capacity of 1,4 GW and will go from the British town of Blyth to the Norwegian town of Kvildal, while the completion of this project is planned for 2021.

The aforementioned contract with Norway will bring savings of up to 3,5 billion pounds to British households over 25 years, as Britain will import cheaper electricity, according to estimates by the British energy regulator Ofgem.
