EnBW, the German electric utilities company headquartered in Karlsruhe, has awarded Siemens Gamesa Renewable Energy with the installation of the neighboring 112-MW-project EnBW Albatros. The scope of supply includes 16 direct-drive SWT-7.0-154 wind turbines on monopile foundations and the grid connection via a Siemens Offshore Transformer Module (OTM). Siemens Gamesa will install both wind power plants in parallel. Installation will start in spring 2018. The projects are located 90 kilometers north of Borkum Island in the German North Sea with water depths of up to 40 meters. The combination of both projects offers synergies to EnBW in respect to planning, construction, and during operation. Due to Siemens Gamesa.
Renewable Energy’s complete solution for Albatros -ranging from turbines to substation technology -the project benefits from full optimization opportunities: Through the project-specific approach, all technology components work perfectly aligned so that the risk for all involved parties is mitigated. At the same time, a bundling of installation works and a centralized project planning create valuable synergies. After commissioning in 2019, Siemens Gamesa will initially provide service and maintenance for the turbines over a period of five years.
EnBW Albatros is the first German offshore wind power plant that Siemens will supply as a full-scope project. Furthermore, it includes the entry of the compact Siemens OTM in the German market. Thanks to focusing on key electrical components and cutting auxiliary systems, it allows a reduction in weight and size of more than 30 percent compared to a conventional AC substation. Further cost out is achieved by using the same foundation type for the OTM as for the turbines. The ultra-compact design of the platform not only reduces installation costs due to its low weight, but also reduces service and maintenance efforts. EnBW Albatros will be connected to the power grid via the Borwin Beta HVDC converter-platform which is located approximately 25 kilometers away and had been delivered by Siemens as well.
The Hohe See and Albatros wind farms are being erected far out in the North Sea: Hohe See is located around 95 kilometres north of Borkum and around 100 kilometres north-west of Helgoland, while Albatros is being constructed 105 kilometres from each coast. On areas covering 42 and 11 square kilometres respectively, both wind farms will generate 2.5 billion kilowatt hours of electricity to supply an aggregate of around 710,000 households from 2019.
