The first of a number of transformers for the Dogger Bank Wind Farm has been delivered. The project is poised to be the largest offshore wind farm in the world when operational, with an overall capacity of 3.6 GW, and it is also poised to be the first HVDC connected wind farm in the UK.  

The transformers will play a role in the operation of three onshore convertor stations in East Riding of Yorkshire and on Teesside, that will eventually convert the current from the wind farm for transmission via the national grid network to UK homes.

This week the first transformer was transported from Port of Hull to the first convertor station off the A1079 near Beverley in East Riding, where construction of a second convertor station is also underway by tier one supplier Hitachi Energy. Three further deliveries are scheduled in East Riding on the mornings of 15, 22 and 29 May, with deliveries for the second East Riding convertor station taking place in 2023.

Heavy lift and transportation specialist Allelys was appointed by Hitachi Energy to carry out and oversee these latest deliveries.

Dogger Bank Wind Farm Transmission Package Manager Børge Angelfloss said: “Successful delivery of the first transformer is an important milestone for our world-leading project.

“Our thanks go to all those involved in ensuring this happened safely, including the local highways authority and representatives from Humberside Police for their valuable expertise on the route between Port of Hull and our convertor station site.”

Hitachi Energy is due to start work on the third convertor station on Teesside later this year. The company is responsible for providing its high-voltage direct current (HVDC) Light systems for all three phases of the wind farm, including the projects three high-tech onshore convertor stations.

Göran Isacsson, Project Director for Hitachi Energy, said: “Hitachi Energy is proud to be connecting the Dogger Bank Wind Farm to the energy grid using HVDC (high voltage direct current) technology.

“The delivery and installation of the transformers at the onshore converter stations we are building are important milestones for the project. We are pleased to have successfully achieved this first shipment and we thank the local authorities and community for their support and patience.”

Located off the north-east coast of England, Dogger Bank Wind Farm is being built in three 1.2 GW phases, Dogger Bank A, Dogger Bank B, and Dogger Bank C.

Dogger Bank Wind Farm is a joint venture partnership between SSE Renewables (40%), Equinor (40%), and Eni (20%). SSE Renewables will to lead on the development and construction of Dogger Bank Wind Farm, and Equinor will operate the asset on completion.

Once the three phases are complete, the project is expected to generate around 18 TWh annually, enough renewable electricity to supply 5% of the UK’s demand and equivalent to powering six million UK homes.

Tier one supplier NKT is leading the work to install the Dogger Bank A nearshore cable, that will connect the first phase of the wind farm more than 130km off the coast to a landfall point at Ulrome, in East Riding of Yorkshire.
