ABB has secured a contract worth over $250m for 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.
The contract requires ABB to supply a 220-kilovolt (kV) high-voltage cable system and alternating current (AC) submarine cable systems for the Eastern and Western circuit.
The circuit will transport green electricity at a distance of about 120km from the wind farm to the UK’s east coast.
The wind farm connection is expected to be commissioned in 2019. It is the third project that ABB 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."
Earlier this year, Dong Energy made final investment decision of the 1.2GW Hornsea Project One offshore wind farm, which is in line with its goal to install 6.5GW of offshore wind by the end of this decade.
Hornsea Project One, which is expected to start services in 2020, is part of the Hornsea Offshore Wind Farm zone that has a maximum capacity of 4GW.
Located 120km off the Yorkshire coast, the project will employ Siemens 7.0MW wind turbine. It is expected to feature between 150 and 332 offshore wind turbines based on the size of the units selected.
