Nordex SE is a European company that designs, sells and manufactures wind turbines, founded in 1985 and headquartered in the German city of Rostock with production in Germany, Brazil, India, Mexico, Poland and Spain. According to the company, it had installed wind turbines with a total capacity of around 50 GW in over 40 countries worldwide by the end of 2023.[2]
History
The company was founded in Give, Denmark in 1985. In 1995 Nordex was the first company to mass-produce a 1 MW wind turbine booster.
On October 1, 2001, the bankrupt company of Südwind Babcock-Borsig was fully implanted into Nordex, which then continued to produce Südwind turbines in the 1.5 MW class (ProTec MD 1,500 kW) from 2001 - originally from "pro + pro Energiesysteme" (a subsidiary of aerodyn Energiesysteme GmbH and Denker & Wulf) developed the S70 and later the S77 - under license..
In 2016, the wind turbine manufacture business unit of Spanish conglomerate Acciona, Acciona Windpower, merged with those of Nordex to form Nordex Group.[3] Acciona S.A. is now the main shareholder of the Nordex Group.[4]
Organisation
The company's headquarters are in the German city of Rostock while management is in Hamburg. Nordex produces at sites in Germany, Brazil, India, Mexico and Poland and Spain. The main production facility is located at the headquarters in Rostock.[2] Nordex has branches and subsidiaries in 19 countries.
Products
As of 2013, the third generation of Nordex wind turbines included two platforms, rated at 2.4 and 3.3 MW.
In Europe, Africa and North America Nordex manufactures and sells the Gamma series, a product family comprising the N90/2500, the N100/2500 and the N117/2400. The N90/2500 is a turbine being developed for strong winds. The N100/2500 consists of two versions, Highspeed and Lowspeed, the first one for rather windy locations, the second for medium wind conditions. The N117/2400 was designed especially for low-wind regions (IEC 3). The hub height of the 2.4-2.5 MW windturbines reaches from 65 meters for the N90/2500 to 141 meters for the low wind version of the N117/2400.

Delta/Delta4000-Class
In 2013 Nordex launched the Delta-Class-Series, entering series production in January 2014 with prototypes installed in mid-2013. There will be two new types of turbines, the N100/3300 strong-wind turbine and the N117/3000, which is designed for medium-wind sites. Both turbines feature the rotorblades already used in the Gamma-Series, with the rotorblades of the N117 being slightly upgraded to withstand the higher wind speeds in IEC wind class 2a. Both turbines are equipped with a three-stage gearbox and a doubly fed asynchronous generator.[6][7]
