Hard on the heels of MHI Vestas Offshore Wind’s announcement of a 10-MW offshore wind turbine, Siemens Gamesa Renewable Energy has unveiled a 10-MW+ unit with 30% greater annual energy production than its predecessor
Siemens Gamesa’s SG 10.0-193 DD offshore wind turbine will have a 193-m diameter rotor that uses the company’s proven direct drive technology 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 m˛.
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 most components from previous offshore wind turbines developed by Siemens Gamesa to be re-used.
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 believed to be working on a larger, more powerful next-generation turbine.
The SG 10.0-193 DD was unveiled following MHI Vestas’ launch of its 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 and is to install the prototype of the turbine at a site in the Port of Rotterdam.
The company has concluded an agreement with Future Wind (a joint venture between Pondera Development and SIF Holding Netherlands) to install the Haliade-X prototype in the Maasvlakte-Rotterdam area mid-2019. The deal includes five years of testing and a 15-year full service operation and maintenance agreement.
The Haliade-X 12-MW prototype will be installed onshore to facilitate access for testing. During the initial period of operations, it will allow GE Renewable Energy to collect the data needed to obtain a type certificate, a key step in commercialising the product in 2021.
GE Renewable Energy vice president and chief executive John Lavelle said, “As we rapidly progress on assembling the Haliade-X prototype, this announcement is a critical step forward for GE and our customers. The Port of Rotterdam provides all the necessary conditions to test the Haliade-X in the most drastic weather conditions.”
Sif Holdings Netherlands will install the Haliade-X 12 MW at the Sif site in Rotterdam and activity to prepare the site for installation has begun. The nacelle of the Haliade-X 12-MW prototype will be assembled in Saint-Nazaire in France. Three 107-m LM Wind Power blades will be manufactured in Cherbourg, France, and the tower sections will be produced in Seville in Spain. All of the components will be shipped to Rotterdam, where pre-assembly work and installation will take place.
The prototype in Rotterdam is part of a US$400M investment in developing the Haliade-X announced by GE Renewable Energy in March 2018.
