Nordex is a German company that designs, sells and manufactures wind turbines. [Several unrelated companies are also named Nordex: Nordex Incorporated (Connecticut; gears and precision assemblies); Nordex Lighting (Italy); Nordex Media aka Nordex Advanced Technology (California); Nordex Explosives (Ontario); Nordex (Chile; frozen food).] The domicile is located in the German city of Hamburg, production takes place in Rostock, China and Jonesboro, Arkansas. The company was founded in 1985 in Give, Denmark. Since then the company steadily grew. In 1995 Nordex was the first company to mass produce a 1 MW turbine.
[edit] Wind turbines
Currently Nordex manufactures two platforms of wind turbines, rated at 1.5 MW and 2.5 MW. The 1.5 MW class consists of the S70, S77 and S82, which are sold in the Asian-pacific markets. In Europe and North America Nordex manufactures and sells the 2.5 MW series, a product family comprising the N80/2500, the N90/2500 and the N100/2500. The N80/2500 is a turbine being developed for strong winds. The N90/2500 consists of two versions, Highspeed and Lowspeed, the first one for rather windy locations, the second for medium wind conditions. The N100/2500 was designed especially for low-wind regions (IEC 3), but can also be used at medium wind. The hub height of the 2.5 MW series reach from 60 meters for the N80/2500 to 140 meters for the low wind version of the N100/2500.
In February 2011 Nordex announced to produce another wind turbine of the 2.5 MW series, the N117/2400. With a swept area of 10,751m² and a nominal power of 2,400 kW the N117/2400 can reach a capacity factor of 40% even under low wind conditions (IEC 3). This turbine will be employed with hub heights of 91 meters (resulting in a total height right below 150 meters) and 140 meters.

[edit] Future
Furthermore Nordex is currently developing another two new turbines. The first one is the 6MW Direct Drive offshore turbine N150/6000 with prototypes announced for 2012 onshore and 2013 offshore and scheduled to enter series production in 2014.[3] The second one will be a 4MW onshore turbine with about 120m rotor diameter that is going to enter mass production in 2013/14.[4]
