Nordex SE is a publicly traded company in the wind energy sector, whose core business is the manufacture, construction and maintenance of wind turbines. In some markets, Nordex is also active in the planning of wind parks to the turnkey construction. The administrative headquarters are in Hamburg- Long Horn. The main production facility is located at the headquarters in Rostock, where the company is registered in the Commercial Register; other production sites are in the People's Republic of China and in Jonesboro (Arkansas ) in the USA. The nacelle production in the U.S. is to be closed due to low demand and global overcapacity in the fall of 2013.
Nordex has branches and subsidiaries in 22 countries. To date October 1, 2013 5646 Nordex turbines with a total capacity of 9394.15 MW were installed worldwide by its own account. Nordex 2010 was the most profitable companies in the country Mecklenburg-Vorpommern.

Nordex A / S came out in 1985 from the Brande Kedel above Beholderfabrik in Svindbæk at Give in Denmark; the latter was founded by Flemming Pedersen and his sons Carsten and Jens. The activities in Germany began in 1991 with the sale by a company founded by Volker König, Werner Napp and Günter Schmidt Nordex Energy GmbH. The following year this company was built in Rerik on its own development and production, which was later re-integrated into the overall enterprise. It was here that in 1995 the world's first series-produced wind turbines in the megawatt class.
In 1996, part of the Babcock -Borsig AG Balcke -Dürr 51% of Nordex. A further 26 % was acquired in 1998. In 1999, as the existing plant in Rerik increasingly proved to be too small, the former Rostock diesel engine plant taken, which formed from now on the main work. 2001 prepared Babcock Borsig due to financial problems the IPO of its profitable wind energy business before. In addition to Nordex included, inter alia, the distribution company NPV, the previously absorbed insolvent wind turbine manufacturer and the south wind, founded in 1999 Borsig rotor. Owner of the transitional society, which was held under Taifun AG, were 80.5 % Borsig Energy GmbH and 19.5% Nordex founding family Petersen. In April 2001, Nordex shares were first listed on the stock exchange ( IPO). On 1 October 2001 Babcock -Borsig gave his remaining stake of 29.8 % at Nordex for around 140 million euros to the West German Landesbank. The Petersen family has been involved with 7% at the former Nordex AG.
In 2003, Nordex entered a crisis. In addition to a general economic slowdown, a decline in the demand for wind turbines and a resulting sharp decline in orders Nordex prepared esp. the large product portfolio with a variety of different types of plant problems, which the company incurred heavy losses. By 2005, followed by a restructuring in which reduces product variety and production was closed at the main plant in Give; also 150 jobs were lost in Germany. In addition, Nordex Energy GmbH and subsidiaries south wind Nordex Energy GmbH were merged. In 2005 there was a capital reduction in the ratio of 10:1 followed by a comprehensive refinancing of the Company after Nordex was in financial difficulties. In this context, the shareholders CMP Management, Goldman Sachs rose a ( indirectly through a fund ) and momentum ( Klatten ). As of 2005, there was a renewed upsurge of the company.
2006 first offshore facility was built in the Breitling Germany and took the Chinese manufacturing for large turbines in operation. As early as 2003 an offshore test facility was built in the Kattegat Sea off the Danish port of Frederikshavn. In January 2007, a rotor blade production facility was opened in China. In early 2008, Nordex was referring back to the previous site in Rerik for training purposes. In October 2008, Nordex announced the investment announced in a new manufacturing facility in Jonesboro in the U.S. state of Arkansas. The official opening of around 40 million U.S. dollars expensive work was carried out in October 2010.
Since March 4, 2010, Nordex has the legal form of a European society.
In early 2011, Nordex moved its headquarters to Hamburg - Long Horn, where the new headquarters was occupied in Nordex Forum. In the same year, Nordex upgraded its main plant in Rostock as one of the first companies in the wind energy sector in order to series production. Instead of the dock assembly used earlier there are now three assembly lines for engine house, drive train and hubs, each be supplemented by three additional pre-assembly. This allowed the production time per turbine will be reduced by 30%; at the same time the maximum annual capacity of the plant increased to up to 1000 plants.
Early November 2011, Nordex announced that Jürgen Zeschky, who was, at that time still manager of the industrial division of Voith Turbo, the position of CEO will take over at Nordex. Some months earlier, Thomas Richterich, who stood at the head of Nordex since 2002, declared not to extend his current contract. The change took place on 1 March 2012.
In December 2012, Nordex completed his rotor blade manufacturing facility in China due to lack of capacity in there heavily protected market. In addition, also restructuring measures at the Jonesboro were announced because of lower utilization. In June 2013, Nordex stated that the nacelle production in the U.S. set and 40 jobs will be eliminated due to low utilization. Available locally were sales, service and project management.
Parallel to this, Nordex is to build the rotor blade production at its main plant in Rostock, according to information in order to increase the depth of production and to reduce costs. The future capacity of its own blade production for the N117 should therefore be 400 blades per year. In addition, Nordex obtains the partially of carbon fiber reinforced plastic NR 58.5 - sheets of the rotor blade manufacturers SGL Rotec and from February 2014 the U.S. manufacturer TPI Composites, whose work is in Turkey. The constructed in a conventional fiber optic technology wing of the N90 and N100 are manufactured both by Nordex as well as from other manufacturers like Wings LM Glass Fiber.
2010 started his Nordex product generation ' gamma '; In 2011 it launched the production of the type N117/2400; 2013 started the production of the types N117/3000 Delta and Delta N100/3300.
In March 2014, Nordex exceeded the threshold of 10,000 MW of installed capacity.
In the Nordex Forum in Hamburg- Horn Long, which was occupied in early 2011, is the seat of the head office and other group companies of Nordex SE. The building was built by Hochtief and is owned by Swiss Life. The gross floor area of approximately 15,000 m² offers space for up to 700 jobs; a further expansion of up to 1,200 jobs has been taken into account in the construction plans. At the inauguration in early 2011 (to which, among other things, the then mayor of Hamburg, Christoph Ahlhaus appeared ) were there employs around 500 people. Special emphasis was placed on good environmental friendliness and low energy consumption, the latter is 20 % lower than conventional office buildings. The relatively good ecological balance has been confirmed by the German Sustainable Building Council, which gave the Nordex Forum the certificate in gold.
In the legal form of a European Company can in principle be chosen between the monistic and dualistic model of the management. Nordex SE has chosen dualistic model; Therefore, the management consists of the Executive Board and Supervisory Board.

In addition, the company is listed on the Nasdaq technology stocks index. From the opening price at 80 euros, the share price initially rose in 2001 to 108 euros, but then fell to the middle of 2005 to a historic low of 1.53. About 75 % of the shares are in free float, the main shareholder with a nearly 25% SKion.
Nordex in the international market
Since founding the company in 1985, Nordex is active on different markets. Next was the home market in Denmark, the main market, the company's focus shifted in the 1990s to Germany, where gradually the production was relocated. There, a market share of 16 % was achieved in 1998, which Nordex was the company with the second highest sales. For this purpose, Nordex exported at an early stage investments in third markets such as India and later China, where in 1998 by a joint venture production has been established. In 2002, Nordex already account for nearly half of the production; in the following years, the export was still significantly increased, while Germany as a market played only a minor role.
From circa 2010, Nordex changed his strategy to the effect that Germany again played a more important. This was accompanied by a focus on inland sites, for starting with the N100/2500, but especially the developed with N117/2400 and N117/3000, new equipment. However, the export share of Nordex with currently over 80 % is still at an above-average level. For comparison, the export share of German wind industry in the first half of 2012, about 66 %, which also corresponds approximately to the long-term average. The market share of Nordex in Germany was in 2012 at 3.5 %, which Nordex rank 5 among manufacturers occupied ( by installed capacity ). By far the market leader in Germany is traditionally the company Enercon were for around 55 % of the total market volume in Germany and also one of the major manufacturers worldwide. Then Vestas followed with about 23%, REpower Systems with 10.6 % and the offshore plant manufacturer BARD 4.3%.
In 2012, Nordex installed turbines with a total capacity of around 920 MW, with 71% and 651 MW accounted for the market segment of Europe, which Nordex, Turkey and South Africa counts. The main markets were here before the UK Germany, Sweden, Italy and France. Worldwide most important market, the U.S. was around 220 MW, where it had come in 2012 to a boom due to the initially feared expiry of the Production Tax Credit. This year also marks the orders shifted further towards the European markets, which accounted for around three quarters of the total order intake of EUR 1 268 million to 967 million euros. Particularly strong growth, new business in Germany, a trend which continued in early 2013; lay in absolute terms the UK with 250 million euros against South Africa, Germany, Turkey and France.
2012 Equipment worldwide were newly installed with a capacity of 44.7 GW, of which 920 MW of Nordex. As a result in 2012 a global market share of 2%. Worldwide had been installed with a capacity of around 282 GW by the end of 2012 wind turbines. Accounted for Nordex 8.5 GW (as of March 2013). The historical market share thus amounts to about 3%. The most important single market for Nordex from a historical perspective is Germany, where until July 2012 almost 2 GW were installed, what about a market share of 6.5 % corresponds to an installed capacity of around 31 GW. In other countries such as France and Turkey Nordex holds against double-digit market share.
Equipment previously manufactured
In the late 80s and early 90s Nordex sold the two plant types N27/250 and N27/150, the latter was an advancement for wind areas. The type of plant was eventually expanded to N29/250. In 1995, the product portfolio was expanded considerably, as Nordex, boarding with the developed prototype of the plants in Germany and N52/800 N52/1000 that were later developed to N54/1000 in the megawatt class. In Denmark, was brought in the same year N43/600 in series production, which Nordex now manufactured systems of three different power classes. The N50/800 formed the technical basis for the later developed N60/1300 and N62/1300.
Technically among all these types of systems to the Danish concept. This means that the rotor had a means of transmission to the generators and these were connected directly to the mains without intermediate power converter. Therefore, the systems had to be synchronized to the mains operated at a constant rotor speed. By pole-changing one for low speed and one speed for high performance was available. The power limitation was made by stall regulation; the blades were so designed aerodynamically umklappende leaf tips that it is too high wind speed came to a stall and the system was thus protected against overload. This concept was simple and cheap to implement, so it many manufacturers came into use in the 1980s and early 1990s, however, efficiency and impact were especially through the rigid rotor speeds, often by a wide margin in addition to the aerodynamic optimum, significantly lower than for later developed regulatory mechanisms. Therefore, this approach proved increasingly obsolete.
Then Nordex developed with the N80/2500 a new wind power plant, the prototype of which was built in February 2000 in the presence of German Chancellor Gerhard Schröder and Wolfgang Clement, then Minister President of North Rhine -Westphalia in the wind test field Grevenbroich. This guy was 2000, the first series-produced wind turbine with 2.5 MW rated power. Followed in 2003 with the N90/2300 one designed for weaker winds further development of this system. In 2007 the family, which also includes the 2005 added N90/2500 Come one, was thoroughly revised. The new facilities were renamed from now on under -generation beta. 2008, the first N100/2500 was erected.
In parallel, made of previously gone bankrupt and taken over by the manufacturer Nordex south wind ( ProTec MD 1500kW ) from 2001 of its 1.5 - MW class - the original "pro per energy systems " ( a subsidiary of aerodyn and Denker & Wulf ) developed S70 and S77 later - under license. These plants possessed a pitch control and fed by inverter into the grid, so they were at a speed variabelen operating in the situation.

Beginning of 2013 was the product portfolio of Nordex from three different platforms. The main product is the 2.5 MW platform with the investments N90/2500, N100/2500 and N117/2400. In February 2013 were also presented with the delta - generation 3- MW platform, which will take effect from 2014 in mass production, and either replace the Gamma Generation in whole or should at least supplement. In the Asia -Pacific and it is necessary of its 1.5 - MW class available.
All three platforms are pitch- regulated and use a conventional plant layout; absorbed by the rotor of the wind energy is translated via a three-stage mechanical gearbox and drives a high-speed double-fed asynchronous generator, which produces electricity at mains frequency of either 50 or 60 hertz means of frequency converters. By this design, the plant will be able to work largely variable speed, whereby a high aerodynamic efficiency to be achieved. Moreover, only around a third of the generator power must flow through the inverter, whereby the power electronics compared to systems with synchronous generator and full can be made smaller. As these, however, a real and reactive power control is possible.
Gamma - class
The gamma -Class represents the third evolutionary stage of the manufactured since 2000 2.5 - MW class and sparked 2010 Beta from the previous generation. In this case also the type classes of the existing plants were raised, so now the N90/2500 for high-wind situations and N100/2500 is suitable addition to low wind sites even for a moderate wind sites. New to add gamma class was specifically designed for low wind conditions N117/2400, which went into series production in July 2012. The N80/2500 (gamma ) also belonged to this platform, but is no longer offered by the wind class raising the N90/2500.
The platform is based on a single modular concept and has been compared to the generation of beta improves both the suitability for higher wind speeds, especially in terms of ease of maintenance. In addition to a rear entrance into the rotor hub, the platform has an internal crane, with the components wait up to a weight of one ton and can be exchanged. In addition, most work can without opening the engine house roof and thus perform weatherproof.
The first series of gamma - class facilities were installed in 2010 at the wind farm Germinon in the French department of Marne. There came 30 N100/2500 used, operator GDF Suez.
The N90/2500 is the strong-wind turbines in the gamma - class. Was the N90/2300 from which it was developed, originally designed for, nor for medium to weak inland sites, the plant in the gamma - class was admitted to a wind class increase in 2011 now accounts for locations of class IEC 1a. So they replaced the N80/2500 that was initially continue to be offered for locations with a height limit of 100 meters, but was eventually taken out of active marketing. Available on the turbine towers with 65 or 80 meters in height, the overall height is 110 or 125 meters.
The Nordex N100/2500 presented before the public in August 2007. The system was developed on the basis of the existing N80/2500 and N90/2500, although a newly developed rotor with a diameter of 100 meters was used. By thus enlarged rotor area of 7823 m² with the same power ( 3.13 m² / kW compared to 2.55 m² / kW at the N90/2500 ) in income should be increased to inland locations. The turbine was thus initially as a dedicated light wind plant with average wind speeds of up to 7.5 m / s ( IEC 3 ) markets. First pre-production aircraft were delivered in 2008, the series production began in 2009. During the launch of N117/2400 in 2011, which now replaced the N100/2500 a weak wind turbine, wind class of N100/2500 was reinforcement of highly stressed parts IEC2 (mean wind conditions up to 8.5 m / s) raised; In addition, the Cut- 20 m / s to 25 m / s was increased. The basic specifications of the plant retaining most, resulting in low to medium wind conditions resulted in an increase in yield compared to the previously used N90/2500 here on sites. The N100/2500 was built initially on steel towers with 100 meter hub height, eventually came to more tubular steel towers with 75 or 80 meters, especially for sites with moderate wind conditions. For low wind conditions with the company Max Bögl a 140 - meter hybrid tower was developed, which was in early 2012 series and is also used for the N117/2400.
When N117/2400 is a so-called weak-wind system, ie a system that has been specifically designed for weaker wind conditions (up to 7.5 m / s average annual wind speed). Characteristic of such wind turbines is a particularly large rotor area per kW of installed power (at the N117/2400 4.48 m² / kW ) to generate relatively high returns at low wind speeds, as well as a high tower, the stronger and turbulence poorer winds in to be able to better tap into greater heights. The N117/2400 thus comes mainly for inland sites in question. Technically, the system is based on the 2.5 MW Gamma - class to which the current assets N80, N90 and N100 belong with 2.5 MW rated power. As this has the system via a transmission which translates the rotor speed to the double-fed asynchronous generator to the higher speed required of the latter. Using partial converters that bring the electricity produced at the power frequency of either 50 or 60 hertz, thus allowing a variable-speed operation of the rotor near its aerodynamic optimum, and a transformer is fed to the electrical energy into the medium-voltage network.
Manufacturers shall N117/2400 is offered on three different tower types which enable total height to the blade tip in 12 - clock - position of approximately 149, 179 and 199 meters. In addition to two 91-meter and 120 -meter-high steel towers is a 141 meter high precast concrete - steel hybrid tower available, which is in the lower range up to a height of 91 meters of precast concrete and the upper area of steel. The area of the foundations of reinforced concrete hybrid tower is at a diameter of 22.5 meters, approximately 400 m², will be installed this about 93 tons of reinforcing steel and 670 cubic meters in-situ concrete. The mass of the nacelle is included drive train and generator 106 tons. The rotor weighs 58.7 tons, including the hub, with a single rotor blade brings 10.4 tons on the scale. Thus, the 58.5 meter long rotor blades of N117/2400 despite the greater length slightly lighter than the almost 50 meter long leaves of the N100. This is made possible, including through the use of carbon fiber reinforced plastic instead of GfK for highly stressed parts of the leaves.
The prototype of the N117/2400 was built in December 2011 in Bürgerwindpark stadum, where the facility s will be approximately 9.9 GWh at an average wind speed of 7.4 m / s. 2012, the first full year of operation, the plant achieved a production of approximately 7.8 GWh, equivalent to about 3250 full load hours despite temporary shutdowns for testing and certification measures. The end of June, 2013, one year after the start of series production, 188 plants of this type were installed. In the first quarter of 2013, approximately 80 % of the new orders of Nordex accounted for this model. 2013 model made the world a good 20 % of the sales made in Germany, there were over 75%. Thus, it was according to the company instrumental in that Nordex its sales in Germany in 2013 could increase by 165 percent.
Delta - class
Beginning in February 2013 presented Nordex before the new product platform generation of public Delta, which is an evolution of the gamma class. The generation Delta consists of three turbines in the 3 MW class, the N100/3300, the latter was officially unveiled until November 2013 N117/3000 and N131/3000.
In each case, a prototype of the N100/3300 and N117/3000 were erected in the summer of 2013 Bürgerwindpark Janneby, another N100/3300 in the Danish testing ground for high-wind conditions at Risø. A few more pre-production aircraft with different tower heights are also already in 2013 [ deprecated] be built. The certification of the two plant types according to IEC and DIBt by TÜV Nord has been completed according to the company in August 2013. Early 2014 [ deprecated] to the N100/3300 and N117/3000 go into series production, the N131/3000 in the second quarter of 2015.
Technically, the equipment is based on the previous generation: it 's still coming in a double - fed asynchronous generator with converter section and a three-stage reduction gear is used, which translates the rotor speed to the required generator speed. However, the engine house was spacious, maintenance -friendly and created a weather-protected, inter alia, direct access through the cable into the hub by Nordex information. All units can be equipped with a Rotorblattenteisungssystem that in winter in cold climates enables a yield increase compared to non-heated leaves.
When N100/3300 is a strong-wind turbines, which is approved for Windbedinungen Class IEC 1a. It thus complements the N90/2500. This uses the same blades as the N110/2500. Can be set up in the N100/3300 on towers of 75 and 100 meters above sea level, thus resulting in a total height of 125 or 150 meters.
The N117/3000 is designed for medium wind conditions. It is the same airfoil used as the N117/2400, however, the rotor blades were reinforced with additional layers of CFRP in order to endure the higher stress levels in the N117/3000 can. The tower versions are based on the predecessors when it comes to the 120 -meter tower of N117/3000 is now suitable for IEC 2a sites also. In addition, the N117/3000 can also be built on a 141- meter hybrid tower as he comes for the N117/2400 used, but only on sites of wind class IEC 3a. This means that overall heights of 150, 180 and 200 meters are possible.
The N131/3000 was presented in November 2013. For her it is a weak wind power plant to achieve particularly at sites with low wind speeds (up to 7.5 m / s average annual wind speed) high yields. Thus it follows conceptually after N117/2400, but both the rated power and the rotor diameter was increased by 25 %. According to Nordex could be reduced by more than 5% of the electricity production costs at low wind sites compared to the previous plant. Also, the sound power level was reduced compared to its predecessor, which compared with some competing systems, the system is considered to be particularly quiet.
Technically, the system belongs to the Delta platform, which it shares many components. A new development, however, were the 64.4 m long rotor blades that are reinforced as with the N117 at highly stressed points with CFRP. While the basic building structure of the leaves remained the same, but the shape was changed and the sheet considerably streamlined in the direction of the blade tip to meet the higher loads and at the same time to make the system quieter. Also, the gearbox was changed to take account of the lower rotor speed and the higher torque. As a generator is still a double - fed asynchronous generator used. Offered was the N131/3000 with steel towers of 99 and 114 meters in height, plus a hybrid tower of 134 meters is available in Germany. With these towers, the system achieves overall heights of approximately 165, 180 and 200 meters. For certain Scandinavian locations and overall heights of 210 meters are planned. The prototype of the N131/3000 is to be built in the last quarter of 2014, mass production in the second quarter of 2015 are included.
There is also a new asset class in the range 3-4 MW are being developed. After the generation Delta appearance but this is uncertain. In this regard questions are not commented by Nordex at the present time ( February 2013 ). Originally, Nordex also wanted to go into the offshore market, finished the development of appropriate turbine N150/6000 but in 2012 due to the uncertain development in this market area. The offshore business - in addition to the development of N150/6000 Nordex is also in the offshore wind farm Arcadis Ost 1 involved - is now to be sold.
In addition to the production of wind turbines Nordex also offers maintenance and service measures at existing plants. A total of four tiered service packages are available; the range is from a host contract which includes only regular maintenance and a 24- hour remote monitoring, to a product marketed as a premium package full maintenance contract. In the BWE service survey 2011, the Nordex service achieved an overall score of 2.77, which Nordex was number four in the German wind turbine manufacturer Enercon behind, REpower and GE Energy and Vestas and Siemens before. 2012 made the service business with a turnover of 119 million euros from about 11% of the total turnover of the group.
Nordex is semi-annually publishes a customer magazine, which reports on news from the company. In addition, products are presented and described developments in individual markets. By 2012, the customer magazine was called the Wind Power Update, published by the total of 35 issues. In early 2013 there was a reorganization and name change to Nordex 360 °, which first appeared in February 2013.
