The 4.2MW 140-metre rotor prototype will be installed at a test site in Blumberg in the north-eastern state of Brandenburg later this year, Senvion stated.
The company’s chief sales officer David Hardy added: "The market demand for our latest turbine platform is very high due to its low levelised cost of energy. We expect a further rise of the interest with the start of the construction of the prototype."
Senvion unveiled two 4.2MW models at the “uåX˜äŠÊ˜·³Ç 2018 event in Chicago in May 2018.
The manufacturer described the 4.2M140 and 4.2M148 models as direct evolutions of its 3MW series, as being "highly modular", and designed to lower transport, installation and service costs.
Senvion will install the turbine before selling it to developer Prokon, a spokeswoman for the manufacturer confirmed.
The developer also signed a framework agreement for 130MW of turbines, including 3.2MW and 3.6MW machines with hub heights ranging from 110- to 165-metres.
An unnamed 14MW project that was awarded capacity in Germany’s most recent auction will be one of the sites where Prokon will install Senvion’s turbines.
However, neither company has named the site or which turbines are to be used there.
Prokon is also not currently able to detail the further seven sites — accounting for the remaining 116MW of the order — where it plans to install Senvion’s turbines, as it has not yet been awarded capacity at auction.
Heiko Wuttke, who sits on Prokon’s executive board, added: "By entering the 4MW class at certain locations, we expect increased competitiveness of our projects in the coming calls for tenders of the EEG (German’s Renewable Sources Act)."
Prokon has 573.7MW of wind capacity either installed or in development in its native Germany and a further 90MW in neighbouring Poland, according to its website.
