The 8.0-154 turbine is in full compliance with the international wind turbine standard IEC-61400-22 and is now available to the global wind market. It is an upgrade of the 7.0-154, where an introduction of new cooling system, new controller and upgrade of the generator enables the higher power output. DNV GL has also been contracted to work on the next upgrade of the 8 MW turbine.
Increasing rated capacity offers a large potential for cost reduction in offshore wind, through corresponding reduction in MW balance of plant and operational costs as well as significantly higher capacity factors. The new Siemens Gamesa wind turbine has a rated power increase of 1 percent compared to the company’s previously certified turbine variant.
Johnny Lillelund, Head of Certification, Siemens Gamesa Renewables Energy, stated the efficient certification process is a result of the longstanding relationship between Siemens Gamesa and DNV GL. This has allowed the company to benefit from a reduced time to market for the new turbine.
