“BLYTH, England — Britain’s economic and political ties to Europe may be fraying, but a growing web of undersea electrical cables binds the nation’s vital power system and its clean energy aspirations to the continent.
The longest and most powerful of these cables was recently laid across the North Sea, from a hydroelectric plant in Norway’s rugged mountains to Blyth, an industrial port in northeast England. Completed last year, it stretches 450 miles, roughly the distance from New York to Toronto. The twin cables, each about five inches in diameter, can carry enough power for nearly 1.5 million homes.
The idea is to use the cable to balance the two nations’ power systems and take advantage of differences between them. In the broadest terms, Britain wants to tap into Norway’s often abundant hydropower, while the Norwegians will be able to benefit from surges of electricity from British wind farms that might otherwise be wasted.”
