Substation milestone for UK offshore windfarm

The substation for a 714 MW offshore windfarm has been installed in the North Sea off England.

The £2.6bn East Anglia One windfarm is located 59 km off the coast of Lowestoft and comprises up to 102 Siemens turbines, each rated at 7 MW. It is operated by ScottishPower Renewables, which is part of Iberdrola.

The substation is one of the largest structures of its kind in the world. The steel jacket weighs 2600 tonnes, is 58 metres tall and sits on four piles, each weighing around 350 tonnes, while the topside weighs around 4200 tonnes.

Charlie Jordan, East Anglia One project director for ScottishPower Renewables, said: “The offshore substation is the single largest and most complex piece of kit that we will build for this project, so it is good to see the structure safely in place.

“Now we will press on with the intricate electrical work, and continue with the installation of the turbine foundations. From the middle of next year, we will start installing the towers and the blades, with electricity being generated before the end of 2019. We are very pleased with progress on East Anglia ONE. It won’t be long now until the windfarm is making an important contribution to the UK’s clean energy goals.”

Known as ‘Andalucía II’, the substation was built by Spanish manufacturer Navantia. Speaking at a ceremony as the substation was handed over, Ignacio S. Galan, chairman of Iberdrola, said: “East Anglia One is a massive offshore project, one of the biggest wind farms the world will have seen. This kind of project represents the future of energy generation – power at scale, without carbon emissions and built at increasingly competitive prices.”
