Danish energy company Dong Energy has awarded a contract to ABB to provide a 220kV high-voltage cable system for the 1.2GW Hornsea Project One offshore wind farm in the North Sea.


Under the $250m contract, ABB will build 120km long cable system to interconnect wind farm with the UK mainland grid.

In particular, the company will supply alternating current (AC) submarine cable systems for the Eastern and Western circuit to enable power transmission.

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."

Designed to power over one million UK households, the Hornsea Project One wind farm is expected to will contribute to the UK’s effort to generate 30% of its total energy production from renewable sources by 2020.

Planed to be commissioned in 2019, the project is part of the Hornsea Offshore Wind Farm zone that has a maximum wind generation capacity of 4GW.

Dong Energy Hornsea Project One program director Duncan Clark said: "Hornsea Project One is record-breaking in terms of scale of energy production, physical size and its distance from shore, and we have worked together with ABB to find the best technical and commercial solutions.

"This joint approach has helped create the right solutions for this large and challenging project and has also enabled us to drive the lifetime costs in the right direction for the next generation of offshore wind sites."

ABB has earlier signed contracts with Dong Energy for the Burbo Bank Extension and Walney Extension links in the Irish Sea.
