All 38 wind turbines at the Kaskasi offshore wind farm in Germany are now feeding electricity into the grid, according to an update shared on social media by Sven Utermöhlen, CEO Offshore Wind at RWE Renewables.
Offshore construction at the project site, located 35 kilometres off the coast of Heligoland in the North Sea, commenced in early March with the installation of the first monopile . The offshore substation, linked with the HelWin Beta platform , was installed at the end of the same month.
Installation of Siemens Gamesa SG 8.0-167 DD Flex offshore wind turbines started this summer and the first unit produced power in August. By mid-November, two thirds of the wind turbines at Kaskasi were feeding electricity into the German grid, while the installation of the remaining units was underway.
By the end of the last month, DEME’s vessel Sea Challenger installed all 38 offshore wind turbines, three of which are fitted with Siemens Gamesa’s fully recyclable blades.
The project team will now run tests under full load, which will be performed over the coming weeks, before Kaskasi starts regular operation at the beginning of 2023 and is handed over to RWE’s operations base on the island of Heligoland.
