World’s longest subsea cable hyperlinks UK to Norway at Northumberland

A 450-mile subsea energy cable linking the UK and Norway on the North East has began business operations, permitting the 2 international locations to share renewable power, Nationwide Grid mentioned.

Water flowing from mountains to fjords and harnessed by hydropower stations in Norway will energy British houses, because the world’s longest “interconnector” hooks up the 2 international locations’ grids with a connection close to Blyth, Northumberland.

The cable will even enable extra wind energy from Britain, when generators are producing excessive ranges of electrical energy in windy circumstances however demand is low, to be exported to Norway to energy houses there.

It will imply the Norwegian grid can successfully retailer power, by conserving water within the Scandinavian nation’s huge Blasjo reservoir which is used to feed hydropower crops, to be used at one other time.

The 1.6bn Euro (£1.4bn) North Sea Hyperlink, a three way partnership between Nationwide Grid and Norwegian system operator Statnett, will assist scale back the burning fossil fuels for energy within the UK.

Nationwide Grid mentioned it will assist keep away from 23m tonnes of carbon emissions by 2030.

The 6in (15cm) large cables which join Blyth in Northumberland with the Norwegian village of Kvilldal, western Norway, will begin by operating with a most capability of 700 megawatts (MW) and progressively improve to the hyperlink’s full capability of 1,400 MW over a 3 month interval.

When it’s at full capability, it is going to present sufficient clear electrical energy to energy 1.4m houses, Nationwide Grid mentioned.

UK Vitality, Clear Development and Local weather Change Minister Greg Fingers mentioned: “As we put together to host the UN Cop26 summit, this pioneering partnership exhibits first-hand how essential worldwide cooperation will likely be in serving to us to ship on our internet zero ambitions and supply clear renewable power to hundreds of thousands of UK houses.”

Cordi O’Hara, president of Nationwide Grid Ventures, mentioned the North Sea Hyperlink was “a very outstanding feat of engineering”.

“We needed to undergo mountains, fjords and throughout the North Sea to make this occur.

“However as we look ahead to Cop26, North Sea Hyperlink can also be a terrific instance of two international locations working collectively to maximise their renewable power assets for mutual profit.”

At Kvilldal, on the sting of a peaceable lake, a converter station has been constructed to allow low-cost electrical energy generated by a hydropower plant located deep contained in the Norwegian hillside to be transmitted to the UK.

Cables from the converter station, which is linked as much as the Norwegian grid subsequent to the hydropower plant, have been laid via the lake and a tunnel to blast via the hill to the close by fjord after which out to the North Sea.

Sub-sea cables carry the renewable energy to a different converter station at Blyth the place it enters the British grid.

The scheme, which took six years, is the fifth interconnector for Nationwide Grid, which additionally operates hyperlinks to Belgium, France and the Netherlands.

The corporate says that, by 2030, 90% of the facility imported through the interconnectors will likely be from zero carbon sources.
