Siemens Gamesa says it will deliver 16 wind turbines with a total capacity of 50 MW for four onshore projects in Germany.
The new projects, located in Schleswig-Holstein, Lower Saxony and Saxony-Anhalt, include orders for a total of 11 turbines of the type SWT-3.0-113, one SWT-3.2-113 and four latest-generation SWT-3.6-130. All four projects will be commissioned this year.
According to the company, individualized planning and flexible technology helped some of these projects to qualify for the necessary approvals: in Geestpark Almdorf, Siemens Gamesa fully met site requirements for air safety with a customized lighting concept. For the Karlum wind farm, electromagnetic shielding of the turbines made it possible for the wind farm to operate close to a radio station.
Notably, the orders were taken in by Siemens Wind Power before the effective merger and, therefore, are not part of Gamesa’s first-quarter results.
Siemens Gamesa says that one gearless wind turbine of the type SWT-3.2-113 will replace a turbine installed in 2002 near Bredstedt in northern Frisia. With a hub height of 92.5 meters and a rotor diameter of 113 meters, the turbine in Geestpark Almdorf reaches a total height of 149 meters.
To ensure the safety of aircraft occasionally passing by from Husum airport at low height, the turbine will be equipped with interfaces that connect to customized lighting. Sensors will control night identification lights so that they are switched on automatically when aircraft approach. The airspace will be analyzed by radar, while sensors will monitor sight and brightness. The operator of the new 3.2 MW wind turbine has entered into a long-term service agreement with Siemens Gamesa for a period of 20 years.
Another four SWT-3.0-113 wind turbines will be installed at the Süderauerdorf wind project, located near Glückstadt on the Elbe river. The project site is located on both sides of the planned extension of the A20 motorway. The four 3 MW units on steel towers, with a hub height of 92.5 meters, comply with the strict technical and building regulations based on their DiBt-type certifications. For the Süderauerdorf wind farm, Siemens Gamesa will also be in charge of service and maintenance for a period of 20 years.
Further north in Schleswig-Holstein, Siemens Gamesa will install seven new turbines of the type SWT-3.0-113 on steel towers with hub heights of 115 meters in the second construction phase for the community wind farm Brebek GmbH & Co. KG, located in Karlum and Ladelund municipalities. Around 280 limited partners from three surrounding communities have participated.
After commissioning, planned for this summer, Siemens Gamesa will be responsible for service and maintenance for 20 years. Like in the predecessor project, the special electromagnetic shielding of the direct-drive wind turbines was a key factor in the technology choice, seeing as the site is situated close to a radio station of the German army.
Siemens Gamesa will also extend the Zerbst wind farm in Saxony-Anhalt with four turbines of the SWT-3.6-130 type. Siemens had already delivered 10 direct-drive turbines for this farm previously. With hub heights of 135 meters, the high-performance 3.6 MW turbines on hybrid towers will offer yield-optimized performance. With the order of four turbines, customer GETEC green energy AG, located in Magdeburg, is expanding its wind farm, situated on a former military air base, where the company operates a future-oriented mix of various regenerative energy sources.
Currently, the installed onshore fleet of Siemens Gamesa in Germany comprises approximately 1,650 turbines with a total capacity of 2,050 MW.
