Siemens has successfully received type certification from DNV GL for its SWT-3.6-130 onshore wind turbine, confirming the new machine complies with international standard IEC 61400-22.
The company said the turbine, which has a rotor diameter of 130 meters, can deliver 18%–19% higher annual energy production than the previous model SWT-3.2-113.
The process started with the certification of the prototype installed at Høvsøre, Denmark.
DNV GL’s work included evaluation of the design supported by tests and measurements as well as inspections.
Following the finalisation of the type certification process, the official certificate was handed over to Siemens at the WindEnergy 2016 trade fair in Hamburg on the 28 September.
The SWT-3.6-130 will go into serial production in early 2017, Siemens said.
