ABB will supply 95 units to GE Renewable Energy as part of its largest ever order for medium-voltage wind turbine converters. The converters will be used in the world's most powerful offshore wind turbines at the Dogger Bank wind farm in the UK, which is playing a key role in reducing the country's emissions to net zero.
The converters are ABB's first significant order under the Long-Term Supply Agreement (LTSA) with GE Renewable Energy. A total of 95 PCS6000 medium voltage converters will be installed in GE's Haliade-X wind turbines with a capacity of 13 megawatts (MW). Currently the most powerful offshore wind turbines in the world, they are expected to generate 1.2 gigawatts (GW) of power in the first phase of the Dogger Bank wind farm in the UK.
ABB's converters are responsible for converting the energy generated by the wind turbines into the voltage and frequency required by the wind farm's grid. They are designed to handle the high power. One revolution of each 220-metre diameter rotor generates enough electricity to power a UK household for two days.
ABB and GE have been working together since 2017 to optimise the PCS6000 inverter for the Haliade-X platform. This included a successful test run on a turbine installed in the port of Rotterdam.
"Selecting the optimal converter is a critical factor in achieving the performance and reliability to maximise return on investment. Medium-voltage converters are the right choice for today's high-power wind turbines," says Günter Stark, key account manager wind at ABB Motion Germany. "By working closely with companies in the wind industry, we have been able to develop innovative technologies for the ever-growing offshore turbines. Therefore, we are pleased to have won GE Renewables' trust for Dogger Bank with our commitment and industry-leading solutions."
ABB in Turgi, Switzerland, is responsible for project engineering. The PCS6000 converters will be manufactured by ABB in Łódź, Poland. The first delivery is expected in summer 2021, with completion scheduled for the end of 2022.
The PCS6000 converter has a solid track record in offshore installations, with more than 250 units in operation in the North Sea, Baltic Sea and off the coasts of China. ABB has also supplied more than 15,000 low-voltage converters to the wind industry.
Dogger Bank wind farm makes significant contribution to UK's renewable energy strategy
The Dogger Bank wind farm is a 50/50 joint venture between SSE Renewables and Equinor and will be built in three phases. It is located over 130 kilometres off the north-east coast of England. The individual phases will have a capacity of up to 1.2 GW and represent a multi-billion euro investment. With a total capacity of 3.6 GW, six million households can be supplied with electricity. The wind farm will make a significant contribution to the UK government's targets of generating up to a third of its electricity from offshore wind by 2030. After commissioning in 2026, Dogger Bank will be the largest offshore wind farm in the world.
