Wind Energy – Installation Substation
Baltic Eagle´s offshore substation topside (OSS) has been successfully installed.
The operation was executed by Heerema Marine Contractors using the Thialf installation vessel. The jacket foundation had been placed on site in October 2022.
The role of the OSS is to collect the electricity generated by the wind turbines and transform the supply voltage before feeding it into the onshore power grid at the Lubmin grid interconnection point.
The move involved the heaviest lifting operation for the Baltic Eagle project with a total estimated net weight of around 4,200 tonnes.
Iberdrola now starts the offshore phase to make the OSS ready for energization. This will be followed by the installation of the monopiles to which the wind turbines are attached with transition pieces. The monopiles have been manufactured by the regional company EEW SPC from Rostock.
Iris Stempfle, Managing Director of the Offshore Division and Deputy CEO of Iberdrola Deutschland, said: “The offshore substation is a key piece of technology for supplying sustainable energy to hundreds of thousands of households and for the decarbonisation of German industry. We are very pleased to have achieved this central milestone in close cooperation with 50Hertz as planned.”
Baltic Eagle is part of Iberdrola´s so-called “Baltic Hub” in the Baltic Sea. Together with Wikinger (350 MW) and the planned Windanker (300 MW), the Hub will have an installed capacity of over 1.1 GW by 2026, underpinning the company’s strategic focus in the Baltic Sea.
