The longest ever built under-sea electricity cable starts its operations

Britain’s National Grid calls 1.6 billion euro North Sea Link has set a record as World’s Longest Subsea Electricity Interconnector. The notion behind the North Sea Link is its harness Norway’s hydropower and the United Kingdom’s resources of wind energy.

The 450-mile subsea cable efficiently connects the United Kingdom and Norway. It has started its operations, allowing both regions to perfectly share renewable energy.

In the last week’s statement, the National Grid of Britain dubbed 1.6 billion euro North Sea Link. It is said to be the largest and longest ever interconnector of subsea electricity.” The North Sea Link is basically a joint venture with Statnett of Norway, the main owner and operator of the country’s network for power transmission.

The concept for North Sea Link is its support to the U.K’s wind energy resources and Norway’s hydropower. According to the National Grid, when Britain’s wind production is high and electricity’s demand is low, the system will easily assist exports to Norway. This will eventually help to conserve water in the latter’s reservoirs.

While Norway has a commendable history of the production of oil and gas and authorities nearly 98% of its electricity yield is from renewables, along with hydropower registering the majority. National Grid previously defined the interconnectors as “The high voltage cables that used for connecting the electric systems of neighboring regions,” thus streamlining surplus trade of power.

The North Sea Links brings together Kvilldal in Norway and the English town of Blyth to have an initial max capacity of around 700 MW. This will eventually increase to a full capacity of around 1,400 MW across a 3-month time period.

In its own declaration, Statnett referred to the 3 months to be the trial period. The comments by National Grid CEO, Statnett’s Hilde Tonne says “As the North Sea Link (NSL) goes for trial operations, I am extremely proud of engineering achievement by our proficient team.”

The National Grid’s North Sea Link is the fifth interconnector — others link to France, Belgium, Netherlands. Now it is forecasted that National Grid will transfer around 90% of the electricity through its interconnectors, which would arise from zero-carbon sources by the end of 2030.

Previous November, plans were declared for a multi-billion pound “the underwater energy super-highway” that allowed electricity generated in Scotland to be transferred to northeast England.

The Eastern Link project, as its prominence, is important on the development of a pair of direct current high-voltage cables that will hold a total capacity of up to 4 GW.

If completely realized the project, which is currently in the initial development stages, would perfectly join places in Scotland, Peterhead, and Torness — in order to Selby and the Hawthorn Point in England.
