Siemens Gamesa Renewable Energy has unveiled a 10 MW+ offshore wind turbine with 30% greater annual energy production than its predecessor.
The SG 10.0-193 DD offshore wind turbine will have a 193-m diameter rotor that uses the company’s proven direct drive technology in order to reduce time-to-market. This is the technology already used in its predecessor, the SG 8.0-167 DD. The 94-m blades provide a swept area of 29,300 m².
The company said the 10-MW machine will be market-ready in 2022 following erection of a prototype later in 2019.
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.”
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.”
The 10-MW rating is made possible through a larger generator, building on the proven direct drive generator technology. The platform allows for the re-use of most components from previous offshore wind turbines developed by Siemens Gamesa.
Siemens Gamesa offshore chief executive Andreas Nauen said utilising proven components and concepts “provides us with a strong, established value chain, with clear processes and skilled employees ready to go, leveraging a fully-developed and industrialised supply chain.”
The nacelles of the new turbine will initially be manufactured at the company’s factory in Cuxhaven, Germany.
“The levelised cost of energy from offshore wind continues to fall as industry scale and performance grow,” said Mr Nauen. “New markets are developing across the globe, all of which require cost-efficient, reliable, and clean power. The SG 10.0-193 DD enables us to meet these needs.”
In the longer term, Siemens Gamesa is working on a larger, more powerful next-generation turbine.
The unveiling of the SG 10.0-193 DD follows MHI Vestas’ launch of 10-MW offshore turbine at Wind Energy Hamburg in 2018, the V164-10.0 MW, which is available for sale now with deliveries from 2021.
In the ReaLCoE project Senvion and partners are developing a turbine that could ultimately be capable of 14-16 MW (a turbine originally touted as a ‘10 MW+’ unit).
GE Renewable Energy is developing the 12 MW Haliade-X, which will have a rotor diameter of 220 m, 107-m blades.
The Offshore Wind Journal Conference in London on 5 February 2019 will address key issues including global market developments, increasing turbine sizes, floating offshore wind and industry regulations. Book your place now.
