Nordex has received an order from RWE to supply and install 11 turbines from the Delta4000 series for two projects in Lower Saxony, Germany.
Seven N149/5.X turbines and one N133/4800 machine are to be supplied for the 44.7MW Lesse wind farm.
The 17.1MW Barbecke wind farm will be fitted with three N149/5.X turbines.
RWE had been awarded contracts for both projects in auctions for onshore wind on 1 February 2023.
Both wind farms in the districts of Peine and Salzgitter are repowering projects in which a total of 17 older turbine models are being replaced by eleven much more powerful machines.
Overall, this will make it possible to double the previous output of the wind farms from 30.6MW to 61.8MW while reducing the number of turbines.
Felipe Villalon Waldburg-Zeil, Nordex director of sales region central, said: “We are pleased to be able to support RWE in the future with our technology in the Lesse and Barbecke wind farms as they move forward to produce more electricity from renewable energy.
“In the case of repowering, less is more.
“Thanks to efficient modern turbine technology, the electricity generated by older wind farms can be increased significantly using a smaller number of turbines.
“In 2022 in Germany 246 turbines with 266MW were taken down and replaced by 103 turbines with 423MW.
“Repowering for onshore wind power will be increasingly important in Germany in future.
“Almost 6,000 older turbines have been in operation for more than 20 years.”
