First ever use of HVDC technology with smaller environmental footprint for connecting offshore wind farms. Dogger Bank offshore wind farms to power 4.5 million homes

ABB has been selected by energy companies, SSE Renewables of the UK and Equinor of Norway to supply its high-voltage direct current (HVDC) Light® converter systems to connect the world’s largest offshore wind farms in the Dogger Bank region of the North Sea to the UK transmission network.

The Dogger Bank development consists of three wind farm projects – Creyke Beck A and B, and Teesside A. It will significantly contribute towards the UK government’s goals of sourcing up to a third of its electricity from offshore wind by 2030. ABB has been awarded contracts for Creyke Beck A and Creyke Beck B.

In the first ever use of the HVDC technology in the UK’s offshore wind market, ABB will supply technology with one of the smallest environmental footprints, due to the most compact station design combined with the lowest energy losses in the power industry. ABB will supply the HVDC Light® converter systems, while Aibel will deliver two HVDC offshore converter platforms. In 2016, ABB and Aibel announced their partnership on the design, engineering and optimization of offshore wind connections.

“Winning the contracts from SSE Renewables and Equinor for the landmark Dogger Bank project underscores ABB’s innovative offshore wind technology and expertise. It also highlights the success of ABB Power Grids’ customer partnerships, both on design optimization as well as on the business model level,” said Claudio Facchin, President of ABB’s Power Grids business. “ABB is committed to delivering sustainable solutions with pioneering technologies and in the Dogger Bank project we are helping to make offshore wind competitive and thus contributing to a stronger, smarter and greener grid.”
