Nordex to supply 34 MW for Rauschenberg wind farm repowering

What happened

Nordex has been awarded a 34 MW contract to repower the Rauschenberg wind farm in Hesse, Germany. According to Enerji Günlüğü, the customer is EEF Erneuerbare Energien Fabrik GmbH, which has ordered five N175/6.X turbines from the manufacturer.

The project will replace five operating turbines rated at 3 MW apiece with five 6.8 MW units. This changes the site’s turbine capacity from 15 MW to 34 MW. Nordex’s scope covers delivery, erection and a 20-year maintenance arrangement. Each new turbine is to be installed on a tower with a 199-metre hub height.

Deliveries and construction are scheduled to commence from the end of 2027. The source expects the upgraded facility to produce more electricity from summer 2028.

Why it matters

The order is a defined example of repowering at an existing wind site: fewer legacy machines are being exchanged on a one-for-one basis for substantially larger turbines. The replacement equipment has more than double the rating of each outgoing turbine, while the number of turbines remains unchanged.

Nordex describes the N175/6.X as a turbine range intended to use stronger, more consistent wind flows at higher elevations. The source says this design can improve energy yield and site use, including during lower-wind periods. The 199-metre hub height is therefore a material feature of the Rauschenberg project, alongside the increase in turbine rating.

For developers evaluating asset upgrades, the contract also combines equipment supply with installation and long-term servicing. The announced schedule gives market participants clear milestones to track: the start of delivery and installation in late 2027, followed by the expected increase in output in summer 2028.

What to watch next

The next reported step should be the beginning of turbine deliveries and on-site installation. Readers should also watch whether the project enters operation on the stated timetable and whether the expected rise in generation begins from summer 2028. Nordex’s 20-year maintenance commitment will continue after installation.
