ABB secured a $250 contract to connect Hornsea project One offshore wind farm to UK mainland grid

ABB has secured a $250m contract to supply a high-voltage cable system that will connect Dong Energy’s 1.2GW Hornsea Project One offshore wind farm in the North Sea to the UK mainland grid.

Under the contract, ABB will supply a 220kV high-voltage cable system and alternating current (AC) submarine cable systems for the eastern and western circuit of the project.

The circuit will transport clean electricity at a distance of more than 120km from the wind farm to the UK’s east coast.

The offshore wind farm connection will be commissioned in 2019.

ABB said this is the third project it will undertake for Dong Energy, after the Burbo Bank Extension and Walney Extension links in the Irish Sea.

ABB power grids division president Claudio Facchin said: “High-voltage cable links are playing a key role in transmitting clean power to millions of people, efficiently and reliably.

“This is another example of how ABB technologies enable the integration of renewable energy and lower environmental impact, a key element of the company’s Next Level strategy.”

In February, Dong Energy took final investment decision of the wind farm, which is in line with its goal of installing 6.5GW of offshore wind by 2020.

Located 120km off the Yorkshire coast, the project will feature up to 332 wind turbines.

Last year, Dong Energy acquired the Hornsea project from co-owner SMart Wind, which sold its 66.66% ownership stake in the offshore development.
