Turbine manufacturer Siemens Gamesa Renewable Energy has unveiled the nacelle for its new 10-MW offshore wind turbine.
Assembly of the prototype nacelle for the SG 10.0-193 DD was completed recently at its workshop in Brande. The prototype is due to begin testing at Østerild in Denmark shortly. The nacelles of the new turbine will initially be manufactured at the company’s factory in Cuxhaven, Germany.
The new turbine will have 30% greater annual energy production than its immediate predecessor, the SG 8.0-167 DD, and a 193-m diameter rotor incorporating Siemens Gamesa’s direct drive technology will its reduce time-to-market, as the technology is already used in the SG 8.0-167 DD. The 94-m blades provide a swept area of 29,300 m².
When it first announced details of the turbine in January 2019, the company said the 10-MW machine will be market-ready in 2022 following creation of a prototype in 2019.
Speaking at the time that the 10-MW machine was first disclosed, Siemens Gamesa chief executive Markus Tacke said the SG 10.0-193 DD combines experience and knowledge from five generations of proven direct drive technology and combines “strong performance, swift time-to-market, and low risk.”
Intended to provide maximum energy yield at all wind speeds, the company said the SG 10.0-193 DD “will offer the same reliability while improving profitability and reducing risk for customers.”
The 10-MW rating is made possible through a larger generator, building on the existing direct drive generator technology. The platform allows for the re-use of most components from previous offshore wind turbines developed by Siemens Gamesa.
As highlighted by OWJ in April 2019, the Dutch windfarm that was the first in the offshore wind industry to go subsidy-free will use Siemens Gamesa’s new 10-MW turbine. Vattenfall has selected the SG 10.0-193 DD to deploy on the Hollandse Kust Zuid 1 & 2 windfarm.
In the longer term, Siemens Gamesa is working on a larger, more powerful next-generation turbine that it hopes to bring to market in the early-to-mid 2020s.
