Dear reader,

in this issue we again want to update you on some of our current projects. The successful installation

of an N80 farm in Norway is particularly encouraging for us for a number of different reasons: Comprising

16 2.5 MW class turbines, it is the largest farm of its type to date. On top of this, its location – only 100 kilo-

meters south of North Cape – is unique and posed considerable challenges during the installation phase.

Yet, it also marks the entry into a new market offering strong potential.

Size matters – this was the case in Germany for a long time. In this country, there is an unmistakable

trend in favor of large turbines. Our most recent orders show that this trend is now also assuming interna-

tional proportions. Customers from France, Ireland, the United Kingdom and other countries are increa-

singly opting for the largest available turbine. Nordex plays a leading role in the series-production of such

turbines and we are doing everything we can to protect this position. To this end, we have unveiled the

latest member of the N80 family – the N90, which went on line at Anklam, Germany, in the summer for the

first time. With its larger rotor sweep, it is ideal for weaker wind conditions (page 4).

In our main market Germany, business has again been very strong this year. As at the end of September,

industry-wide new installed output was up roughly 35 % on the previous year. At the same time, Nordex

was able to widen its market share to 11 % in the third quarter. We expect to receive further upwind of the

continuation of the SPD/Green coalition government. The favorable results of the Green party in particular

show that people in Germany attach importance to the careful use of natural resources. This is also reflected

in recent opinion polls (page 22).

I wish you pleasant reading

ı TechnologyWINDPOWERUPDATE4

Nordex AG has assembled the newly developed

N90/2300 kW wind turbine near Anklam in the

German state of Mecklenburg-West Pomerania for

its customer Enertrag AG, Nechlin. With a rotor dia-

metre of 90 metres and an output of 2.3 MW, the N90

is one of the world’s largest series-produced wind

turbines.

Compared with the base N80 model, the N90’s

rotor diametre is 10 metres larger. This translates

into a 27 % increase in rotor sweep to 6,362 square

metres, roughly the area of a football field. “This

sweep plays a key role in energy yield, which is why

the N90 promises far greater efficiency than existing

turbines in locations characterized by weak to me-

dium wind speeds,” explains Dietmar Kestner, CEO

at Nordex AG.

Nordex will also be offering the N90 on towers

with a height of between 80 and 105 metres to har-

ness wind power potential in non-coastal locations.

This is important because wind speeds and hence

also the energy yield increase significantly with rising

altitude in non-coastal regions in particular. The 80

and 100 metre versions of the N90 are certified for

average wind speeds of 8.0 m/s and the 105 metre

model for wind speeds of up to 7.5 m/s. Accordingly,

the core market for the N90 will be Central Europe.

Says Kestner: “We are currently registering strong

demand in Germany in particular. Preliminary con-

tracts have already been signed.”

The turbine is based on the proven mechanical

concept used in the N80/2500 kW, which has been in

production for the past two-and-a-half years. Accord-

ingly, Nordex assumes that a testing period of only

around six months will be necessary, during which

time Nordex will be measuring the performance

curve, noise emission, grid compatibility and mech-

anical load. The turbine has already been certified pur-

suant to the Germanischer Lloyd guidelines and IEC.

Nordex Extending Rangeof Megawatt Turbines

The N90/2300 kW has been installed near Anklam in Germany. With a rotor sweep of

6,362 square metres the optimum yield has been assured.

section is mounted ...

... and followed by the top tower section.


Numerous detail solutions testify to the maturity of the series,

while the oil-cooling system marks a new development for

Nordex: the turbine is fitted with a permanent pressurized

circulating lubrication system and a larger filter volume. A tem-

perature-based pump control system avoids major fluctuations

in the temperature of the oil sump, protecting the transmission

and the bearings from excessive wear and ensuring reliable

operations.

If it does become necessary to replace a component, the ex-

pense involved is limited. Even key components can be removed

without dismantling the entire drive line. The modular assembly

concept also heightens flexibility during the construction phase.

The maximum weights are 40 tons, representing an advantage

in terms of crane costs and facilitating assembly in rough terrain.

One particular advantage in densely populated regions is

the low noise levels exhibited by the N80/N90 series during

operation. Whereas favourable readings of less than 104 dB are

already achieved during operation at the turbine’s rated capac-

ity, noise emission drops to below 100 dB in the reduced-noise

mode. Thus, by lowering the speed in sound-critical locations,

it is possible for the turbine to continue producing electricity

even during the night.

The nacelle ...

... and the hub are prepared to be installed.

The first blade is mounted to the hub. The installation of the powerful wind turbine is completed.

T he time of large-scale power plants has passed.

The 1,000 MW blocks driven by fossil fuels and

nuclear power stations are gradually disappearing

from the scene. The reason: they are too expensive

and inflexible for the energy production of the fu-

ture. For this reason, today more and more suppliers

are making use of a mix of decentralized energy pro-

ducers. In this way it is possible to generate electric-

ity and heat locally and thus avoid energy losses

resulting from long transport distances. In addition

to this, decentralized power-plant structures are able

to react more flexibly.

However, in order to be able to guarantee a se-

cure power supply, an intelligent control system is

required for the distributed units. Here, the key con-

cept is the “virtual power plant”. A topic which is

now also being worked on by the experts of Natcon7,

a subsidiary of Nordex AG. “We want to produce the

first prototype of energy with the aid of wind power,

solar energy, photovoltaics, hydro power, biomass,

biogas and geothermal heat. The use of these renew-

ables and the conversion into electricity and heat is

effected at different locations. The distributed en-

ergy producers are run as an intelligent association

by means of special automation and information

technologies”, explains Dirk Adam, CEO of Natcon7.

The combination of many decentralized energy

producers to form a virtual power plant ensures a se-

cure supply and is extremely economically efficient.

An existing virtual power plant can be extended to

include further producers at any time. The location

is of no consequence. As a virtual power plant is com-

pletely neutral in terms of technology, machines

made by different manufacturers can be integrated

into the association.

This means that the road is clear for a mixture of

renewables. The combination of different forms of

renewable energy offers enormous advantages for

the operator as fluctuations in supply and demand,

resulting from weather conditions or changes in

energy consumption, for example, are easy to com-

pensate for. Here, it is important to also include per-

manently available producers, such as biomass and

CHP (combined heat and power) plants, as well as –

in the future – fuel cells. This makes it possible for a

virtual power plant to react much more flexibly in

changing energy demand than a conventional large

power station is able to.

Each integrated producer is connected to the sup-

ply grid and has his own control system which

is in direct contact, via an interface, with the central

control system of the virtual power plant. As a result

of this connection, the central control system knows

which individual and total capacity is currently avail-

able. The central control system is equipped with

further communication interfaces, via which it is pro-

vided with additional information. For example, the

central control system is able to evaluate weather

forecasts for the individual locations as well as data

on the current and expected demand situation on

the energy market. The sale of surplus electricity on

the energy exchange is included. This means that

the central control system is in a position to coor-

dinate the power generation of the association

efficiently and in line with demand on the basis of

reliable information.

?Did You Know That...• from October to December this year, Nordex installs almost 2 wind

turbines each day in each week somewhere in the world.

• the wind energy sector uses 300,000 tonnes more steel than the Ger-

man ship building industry.

• in France, trucks with Nordex wind turbine parts of up to 29 metres

had to pass over a local petanque field in order to get through a very

narrow turn. This was done according to an agreement with the mayor

of the village, and of course, Nordex rebuilt the petanque field after

use.

• during the last decade, the investment costs in a wind turbine have

been deducted with more than 50 %.

• the wind energy saves external costs corresponding to an amount of

2.5 – 20 Ct/kWh.

The combination of many decentralized energy producers to

form a virtual power plant ensures a secure supply and is

extremely economically efficient.

The virtual power plant reacts much more flexibly in changing

energy demand than the conventional large power station is

able to.

ı EuropeWINDPOWERUPDATE8

The 16 turbines with a total output of 40 MW mark a turning

point in the country’s energy industry. They will be produ-

cing 120 gigawatts of clean electricity each year in attempt to

address the problems that Norway is experiencing in ensuring

secure supplies of electricity. Formerly a major exporter of hydro-

electricity, the country is now consuming almost as much

electricity as it is producing. Thus, in 2000, it used 125.5 terra-

watthours. By contrast, it produced some 142.2 TWh of hydro-

electricity, accounting for 99 % of total electricity output. Thermal

power stations contributed a sizeable 731 GWh, while wind

power remained on the sidelines, contributing only 30 GWh.

“I am pleased that the community of Måsøy is now also

generating energy”, says Ingalill Olsen. “Finnmark is the cold-

est region in Norway but only covers 15 % of its own energy

requirements”. The town mayor is sitting in her office opposite

the port. From her window, the 287 meter high Havøygavlen,

home to the new turbines, can be seen.

Norway Has Discovered Wind

Wind Power atthe Arctic Sea

In Havøysund, Norway’s largest wind farm to date has gone into operation.

The Nordex 40 MW wind farm at Havøygavlen.

Nr. 15 ı December 2002 9

The wind farm starts five kilometres above the port facili-

ties. All of Havøysund’s five roads used to end at the town’s last

houses. Now, there is a gravel road leading up the hill behind

the cemetery. The dark stone is covered only by moss and lichen.

The 16 turbines operate at altitudes of between 250 and 280

metres, with the 80 metre high towers providing a fantastic view

across the Arctic Sea.

Havøygavlen lies at the end of the world, which is why

Nordex has fitted the 2.5 MW turbines with a power crane

system; a special facility developed for offshore use. In this way,

all main components can be replaced without the need for an

external crane, allowing time to be saved and doing away with

the need to transport heavy equipment.

Ingalill Olsen has been observing the construction work from

her desk since April 2, 2002. The most important woman in the

town watched the 11 kilometre network arising on the hill. She

also heard the explosions when holes were dug in the naked

stone of the hill for the 16 base elements, each one three metres

deep and ten metres in diameter. She watched the heavy trans-

porters and the Caterpillar lug the individual turbine parts up

the mountain and technicians from Denmark and Germany

assemble the turbines as quickly as possible under the midnight

sun. The wind turbines have been watching over the fishing vil-

lage since August 22.

The 21 Måsøy town elders were unanimously in favor of con-

structing the wind farm – not only because it created a number

of long-term jobs but also because they all realized the advan-

tages of “good energy”. “This location offers decisive advan-

tages over other places,” says Ingalill Olsen. In addition to our

port and the support on the part of our population, reindeer play

a key role in this region, wandering between the summer fields

along the coast and the winter locations in the interior. How-

ever, as there are no reindeer on the island of Havøya, nego-

tiations with the locals were not necessary.

The wind farm generates enough electricity for 6,000 house-

holds. In Germany, this volume of electricity would be sufficient

for seven times as many households. However, no other country

in the world consumes as much electricity per capita as Norway.

And nowhere is this truer than in Finnmark. In fact, Ingalill Olsen

alone needs around 28,000 KWh per year. The country’s energy

ministry is expecting a further increase in consumption. For this

reason, parliament passed a bill in March 2001 providing for the

establishment of a state energy agency. Its duties will include

revising energy policy, promoting regenerative sources of en-

ergy and implementing measures to ensure more efficient use

of energy. Known as Enova, it commenced its operations in

January 2002. At this stage, Norway had 28 wind turbines with

an output totalling 17 MW.

The Havøygavlen wind park is a decisive step towards reach-

ing the national goal of generating 3 TWh from wind power by

2010. A further five projects with total annual output of 605 GWh

have already been approved. “We consider the target to be real-

istic and are sure that we will achieve it by 2010,” says Dr. ing.

Magnar Førde, director of regenerative energy at Enova.

The world’s northern-most wind farm is a reference project

for both Norway and for Nordex, which assembled the 16

turbines on a turn-key basis for operator Arctic wind, a joint ven-

ture forged by Norway’s largest industrial group Norsk Hydro

and Dutch utility Nuon as well as the planning agency Norsk

Miljøkraft. Enova contributed 3 8 million to the 3 40 million

project. “This wind farm marks the entry to an interesting new

market for us,” says Dietmar Kestner, CEO at Nordex AG.

Nordex is now also engaged in negotiations with Norsk

Miljøkraft concerning a 200 MW wind farm 500 km south of

Havøysund.

“Conditions here on the coast are ideal for our N80 turbines,”

says Tage Christensen, project manager at Nordex. The climate

is moderate thanks to the Gulf stream, with winter tempera-

tures rarely dropping below minus 26 degrees Celsius. On the

other hand, there is a steady wind with an average annual speed

of 9 metres per second. If the wind speed exceeds 25 m/sec, the

turbines automatically disengage. Although construction work

was interrupted for five days due to a gale twice this speed, the

40-year old mechanical engineer sitting in his office container

at the port says that this was an exception. “This project is also

a test for our offshore units.” Looking forward, Nordex also

wants to assemble the N80, the world’s largest series turbine,

in offshore locations.

Reduction of CO2

Emissions by 20,000Tonnes Per Year

The nine giant Nordex wind turbines at the refinery Nerefco, Europoort Rotterdam

in the Netherlands, have now been erected and since the end of November 2002, the

complete wind farm of 22.5 MW has been in operation.

Wind Energy at the Nerefco Refinery

“Very intensive coordination work has been

carried out before the mounting of the

N80/2500 kW wind turbines at the Dutch refinery”,

says Jan Gräff, Nordex Project- and Site Manager.

“First of all, the existing safety rules had to be fol-

lowed when working at the refinery.” Therefore,

safety training was required before the staff were

allowed to work at the site, and also the site organi-

sation had to be certified to meet the safety stan-

dards. Furthermore, risk assessments required that

the crawler crane had to be disassembled before

moving it from one place to another. This was done

in order to minimise the risk of it falling into a tank

at the refinery.

Then, also according to the safety rules, each wind

turbine has been installed with extra safety equip-

ment. Lifts in the turbines are one of the special fea-

tures in order to make safe access possible for the

refinery’s employees. Furthermore, automatic fire

extinguishing systems have been installed in each

nacelle as well as a lightning sensor system for

Wind power and oil,

fuel and wind energy.


switching off the wind farm in case of lightning, a

connection of the NC2 and the SCADA computer to

the control system of the refinery and an ice sensor

on each nacelle for switching off the turbine in case

of possible ice on the blades.

The installation of the wind turbines went accord-

ing to schedule. When one turbine was erected

the main crane was dismantled, moved to the next

foundation, and assembled again ready to erect

the next wind turbine. While one team was erecting

the wind turbines, another team made the final in-

stallation and commissioning of the erected wind

turbines.

The customer, BP, is on target to successfully com-

plete its first major wind power project, and new

projects of this kind are expected to follow. In this

connection, Nordex will be considered as a possible

supplier and once again have the chance to prove

its performance in the megawatt projects.

Offshore Wind Power

Germany: From EuThe offshore market will dominate the future of wind energy. But in Germany, not

before the second half of this decade. The political will is the key to the break-

through. And the maritime technology for the foundations and installation vessels

must make progress in order to keep costs within reasonable limits.

Offshore: Stronger winds and higher yields. With the development of the 5 MW machine, Nordex aims at maximum yield on the sea.


For some time now, one concept has been electrifying the

wind energy sector: everyone is talking about “offshore”.

Hardly a day goes by without yet more apparently major con-

tributions being added to the public debate on the use of our

oceans. But only some 100 MW of capacity are currently instal-

led off the coasts of Europe. This represents approx. 0.4 % of

installed wind power capacity worldwide. And in Germany?

Nothing doing. To date, the precautionary principle has pre-

vented even the smallest steps offshore. So where does the

euphoria come from?

Experts from the Danish consulting company BTM-Consult

estimate the wind energy potential for the European seas at up

to 125,000 MW. They reckon that German coastal areas alone

could provide 20,000 MW. Huge against the backdrop of the pre-

sent 25,000 MW of installed capacity – worldwide! According

to Greenpeace expertise, if the German offshore potential is

optimally used, a good half of the electricity consumption in

Germany can be covered alone by wind power generated at

sea. Yet, according to estimates by the German Wind Energy

Institute, the offshore market will not take off until the second

half of this decade. Then finally in Germany too. Just in time to

compensate for the lack of space onshore. German wind energy

companies which, unlike Nordex, are not involved in foreign

markets have to trust this forecast.

Nevertheless, the advantages of offshore operation are

obvious: thanks to the strong and more constant winds at sea,

higher yields can be obtained than onshore. At the same time,

the machines are subjected to lower strains as a result of redu-

ced turbulence. The consequence: reduced wear on the turbine.

The real challenges are technical in nature. Adapting the

machine to offshore conditions does not present a major

problem: the electrotechnical units are moved from the foot to

the head of the unit and the machine house protected against

the saline atmosphere by means of a dehumidifier. The addi-

tional costs involved are quire reasonable. However, the situa-

tion is different for the foundation and for installation. This is

where the main cost blocks are involved which make an

offshore project up to 50 % more expensive than wind parks

onshore. Gravity foundations are used today for projects real-

ised in shallow coastal waters. But the future lies 30 to 40 kilo-

metres offshore, at water depths of down to 40 metres. Here

different methods have to be used, such as the monopile or tri-

pod – much more expensive foundations. So the aim pursued

by manufacturers of wind turbines is clear: installation of the

maximum possible yield potential on each foundation. This

is why Nordex is developing a new, large turbine in the

5-MW class. The objective is to make the costs per kW specific

to offshore operation both calculable and economical.

In addition to this, the installation concepts at sea are based on

platforms and ships with lifting devices which independently

raise themselves above the surface of the water, thereby offer-

ing a stable working platform. These too are unsuitable for trans-

port in heavy seas and cannot work continuously. This means

that the actual process of erection must be made faster and so

more cost-favorable.

In Germany, it is high time for the first pilot projects to be

realised if a breakthrough is to be made in the offshore market.

These will enable manufacturers and partner companies to gain

initial experience with offshore units. It is not only the wind

energy sector and the shipyard industry that will benefit. 6 mil-

lion tons of steel are needed to build the units solely to exploit

the German offshore potential of 20 gigawatts. This is approxi-

mately equivalent to the quantity of sheet steel produced annual-

ly throughout Europe.

phoria to RealityThe market for wind turbines will grow by approx.

20 % per annum in the coming years. Especially in

Spain, the USA, France and Great Britain. The German

market too will continue at a high level in the next few

years.

However, another topic also has to be considered:

offshore application. By the year 2006, wind parks with

a capacity of several thousand MW could be created in

European coastal waters alone.

The Merdelou wind farm at sun set.


Mr. Björn Mummenthey and Mr. Vincent Deroubaix,

both Nordex Project Engineers in France, atten-

ded the event, and the following is their story about

the 12 x N60/1300 kW wind turbines:

“On September 6, 2002, we had the great honour

to represent Nordex France during the inauguration,

organised by the customer Enertrag International, of

the two French wind farms Merdelou and Fontanelles.

After the official inauguration in the town Moulin

Mage with all the associates of the projects, several

buses went to the site with all the invited in order to

proceed with the ribbon cutting ceremony by the offi-

cials of the two communities Peux-et-Couffouleux

and Brusque. The successful day ended with a very

nice French buffet.

Before this official day, many years of planning

and work had been carried out. Since 1996, the pro-

ject has been a Nordex France project, developed by

the known French developers Valorem and Energies

du Midi. At that time, Nordex was represented by

Mr. Gerd von Bassewitz, today the Managing Director

of Nordex France SAS.

The final building permit with12 Nordex machines

was obtained on December 13, 1999, and delivered

by the prefecture of Aveyron. The project has final-

ly been taken over in 2000 and realised by Enertrag

International.

Ribbon CuttingCeremony inSouthern France

Inauguration

In September 2002, the two wind farms Merdelou and Fontanelles were officially

opened, and the ceremony which among other things offered a visit to the wind

turbine farms as well as a French buffet, was attended by a huge number of wind

turbine-interested people.


The site is exceptional for several reasons: The two projects

consist of 12 x N60/1300 kW GL1 turbines with tubular towers

and a hub height of 46 metres. The wind farms are estimated to

produce a total annual power output of 61,700 MWh, and with

a total of 15.6 MW they are the biggest wind farms installed in

France so far.

The mean annual wind speeds are 10 m/s at the Fontanelles

hub height and 10.4 m/s at Merdelou which makes this project

very particular and attractive to investors. It is considered to be

one of the best sites in France and is located at an altitude

between 980 metres and 1040 metres above sea level on the

exposed ridges of the French Massif Central.

Due to this site location, the conditions for the Nordex erec-

tion teams were a big challenge. The erection period was in the

winter and the early spring with loads of snow and ice, but due

to the exceptional performance of the site- and erection teams

from Per Henriksen and Mikkel Mæhlisen, the two wind farms

have been in operation since February 2002.

WINDPOWERUPDATE16 ı Europe

Successful Course Continues

New French Orders

Orders received for 16 turbines in France worth a total of 5 21.5 million

In August 2002, Nordex received two new orders from France,

entailing a total of 16 turbines worth a combined 3 21.5 mil-

lion. The two projects are to be completed at the beginning of

2003.

Nordex is handling the Bouin project for its customer SIIF

Energies, a 35 % subsidiary of EDF. The eight N80/2500 kW tur-

bines are to be installed at two wind farms located roughly 30

kilometres south of Nantes. The close proximity to the Atlantic

and low turbulence means that the turbines will be constructed

on 60 metre high steel-tube towers. Nordex will be supplying

the farms as turnkey projects including access routes, founda-

tions and grid connection.

The Bouin project marks the first order after the signing of

the master contract between Nordex and SIIF in April 2002,

under the terms of which Nordex is classed as one of SIIF’s pre-

ferred suppliers. The two companies have also worked together

successfully in the past. Thus, Nordex built two wind farms

for SIIF on Corsica in 2000 comprising a total of 20 N43/600 kW

turbines.

Nordex received the second order from private-sector power

station operator Hydelec. Under the terms of the contract, it will

be supplying four N60/1300 kW and four N43/600 kW turbines

for the Rivesaltes project near Perpignan. The project does not

include access routes and foundations.

The Tuchan wind farm.

In October 2002, Nordex installed and commissioned ten

N50/800 kW wind turbines at the Avignonet site in the south-

ern part of France. The Nordex erection team in France had just

accomplished the enlargement of the Tuchan wind farm with ten

more N43/600 kW wind turbines. Today, this wind farm counts

15 of the well-proven N43/600 kW machines. The latest commis-

sioned wind farm – Avignonet– is located 30km east of Toulouse

and is dominated by the local wind “vent d’Autan”. The turbines

have been erected on 50-metre tubular towers, and the instal-

lation began in the middle of August 2002. At times, the well-

trained Nordex team were erecting up to one N50/800 kW per day,

Olivier Sing, Nordex Junior Project Manager in France, tells.

Nordex France received the Avignonet-order earlier this year

from the joint venture between Seris Eole, a French developer

and the Canadian company Boralex. The project has been devel-

oped within the context of the program “Eole 2005”.

The wind farm has already attracted the attention of the local

population, and weekend promenades to the Nordex turbines

are a common sight. More Nordex turbines will soon be erec-

ted in France, and you can read more about these projects in

the article below.

French Success

During the last few years, Nordex has commissioned one wind turbine project after

another in France, and the success will continue in the years to come.

Nr. 15 ı December 2002 17

The repowering boom is sweeping over Denmark, and today an important replace-

ment of small and old wind turbines by new and more powerful wind turbines is

taking place.

It is expected that before the end of 2002, more than 200 MW

will be installed replacing about 70 MW derived from old and

small wind turbines. Nordex is involved in the Danish repower-

ing program by several projects using the well-proven N50/800

kW and N60/1300 kW machines.

The biggest Nordex repowering project is located at the

Danish island Bornholm in the Baltic Sea. Eight N60/1300 kW

and three N50/800 kW turbines are to replace approx. 35 old wind

turbines ranging from 20 kW to 99 kW. In Jutland, along the ferry

port of Ebeltoft facing to the Kattegat Sea, Nordex will install

four N60/1300 kW wind turbines. These new and efficient wind

turbines will replace 18 old turbines each of 55 kW, and once

described as the first offshore wind farm in Denmark. The last

Nordex repowering projects are dispersed over the country in

the southern part of Jutland. 24 small wind turbines are being

replaced by three N50/800 kW and two N60/1300 kW. All the

Nordex repowering projects will be installed this year.

The Danish repowering program was implemented in 2001,

the purpose being to reduce the number of small and old machi-

nes (less than 150 kW, however most of the replaced machines

have a capacity of less than 100 kW) and to increase the wind

generation capacity. The program will continue until the end of

2003. According to the program, the projects being installed in

2002 are entitled to receive an average of 3 0.08 per kWh for the

first 12,000 full load hours of operation (approx. 5 years) then

dropping to 3 0.058 per kWh for the next 22,000 full load hours

(approx. 10 years). From January 1st, 2003, the kWh prices drop

to the market price plus a subsidy of 3 0.013 per kWh for turbi-

nes installed after that date. However the limit is 3 0.048 per kWh,

so if for instance the market price per kWh is 3 0.040, the sub-

sidy will be limited to 3 0.008 per kWh.

Therefore, the Danish wind turbine market will reach a dead point

in 2003, at least in the beginning of the year, Jørn Motzkus,

Sales Manager Nordex, expects. However, he envisages that

the Scandinavian electricity market will change drastically with-

in the next few years. On the one hand, the Scandinavian grid

infrastructure will be even more efficient, and the grid system in

Denmark, Norway, Sweden and Finland will be more and more

integrated and soon become one system. On the other hand, a

general lack of power in these countries will occur favouring

the use of power from wind energy. Several incidents support

this forecast. The demand for electricity is increasing and will

continue to increase in the coming years, and the existing power

supply will not be able to match this demand. For instance, in

Norway, the demand for power is increasing by approx. 2 % per

year, and at the same time, the country has decided not to extend

the installations of hydraulic power stations as a further exten-

sion will have too much impact on the nature. Today, Norway’s

electricity is 100 % hydraulic power. A possible drought one year

will have a serious influence on the electricity market. The power

prices will rise, and even a rationing of the power might be a

consequence. The higher power prices and the insufficient power

supply will favour the development of new power production

capacity, including wind power.

The Nordex Group has received a follow-up order

from its Japanese partner Ishikawajima-Harima

Heavy Industries (IHI) for the next stage in the

Minami Osumi wind farm project. The Group will be

supplying 10 N60/1,300 kW turbines worth around

3 7 million. A year ago, Nordex received an order of

the same magnitude from its partner. IHI will be

assembling the first ten turbines in November 2002

for its customer Kyushu Electric Power, with com-

pletion scheduled for March 2003. At the same time,

a further 10 turbines are being supplied to IHI for the

next stage of the project.

With 20 turbines and a nominal output of 26

megawatts, the Minami Osumi project will be one of

the largest wind farms in Japan. Located close

Strong Partners in Japan

Nordex and HIDROERG Recursos Energéticos, S.A., placed in

Lisboa, started negotiating in 2001 to develop the Bulgueira

Wind Farm placed at an average altitude of 1100 m above sea

level. HIDROERG trusted once again the turnkey installation of

the project to the long-time qualified Nordex group supplying

the wind turbines, the electrical installation and civil works.

Nordex cooperates with a large number of Portuguese companies

according to its compromise of contributing to the local market

as far as the site of wind farms is concerned.

After evaluation of the wind measurement and site conditi-

ons, the N50 was concluded to be the most profitable wind tur-

bine. With a proved power curve, this machine is particularly

suitable for sites of this kind and has been successfully installed

in many countries. The installation of the three wind turbines

took place in late 2002.

The project required the following civil works: preparation

of the access roads to the 10/60 KV substation, building of

foundations and platforms, trenches and the control building.

Likewise electrical installation works such as the medium-volt-

age grid cells, earthing and the 60 KV cabling are included in

the electrical installation works.

With the establishment of our company in Spain and

Portugual in early 1998 and with the projects recently carried

out, Nordex plays today a leading role within the Portuguese

wind energy market.

to Nejime and Sata at the southern tip of the island of

Kyushu at altitudes of between 420 and 520 metres,

the farm promises excellent yields thanks to average

annual wind speeds of 7.2 m/s.

L ast year, Japan was one of the world’s fastest-

growing wind power markets (+193 %). In 2001

alone, a volume of 217 megawatts was added to the

grid. Experts project sustained strong demand thanks

not only to the favorable wind conditions but also to

government subsidies: wind park operators receive

grants of between 33 and 40 % of their investment

costs as well as feed-in remuneration of 7.8 – 8.9 euro-

cents per kilowatt/hour.

The Prairie Winds: Energy in Motion wind park, a joint pro-

ject between Basin Electric Cooperative and Central Power

Cooperative, is located near Minot, in the far north central region

of the state. With a generating capacity of 2,600 kilowatts, the

two N60/1300 kW Cold Climate Version turbines will produce

enough electricity to power nearly 700 US-homes each year.

Construction of the wind turbines with 60-metre tubular towers

was completed in October 2002.

Basin Electric already offers consumers coal- and oil-gene-

rated electricity, as well as hydroelectric power from dams along

the Missouri River. “Prairie Winds is an important addition to the

regional power supply by offering another renewable resource for

cooperative-served customers,” Ron Rebenitsch, Basin Electric’s

manager of member marketing, said. In an interview with the

Minot Daily News during the initial construction period, Basin

Electric’s Randy Bush added that with the “wide band of good

wind” that characterises the Minot site, it is a prime area for

electricity generation.

“Obviously, Nordex is quite happy to have been selected by

Basin Electric to put up more turbines in their service territory.

It is another challenge for operating in such extreme (hot and

cold) climatic conditions, but the CCV turbines should fare OK,”

noted John Fedorko, President of Nordex USA. “We are pleased

to be associated with Basin Electric as they lead the way in instal-

lations in one of the best wind resource areas in the United

States.” Nordex will also be providing the operations and main-

tenance on those turbines.

The Dakotas region has attracted increased attention recent-

ly from renewable energy companies and public officials for its

potential as a vast and relatively untapped source of wind power.

The new Minot park and its sister park in Chamberlain, SD (see

Windpower Update no. 14, August 2002), both of which show-

case the N60 machine, will become part of the region’s trans-

formation into what North Dakota Governor John Hoeven refers

to as the future “Saudi Arabia of wind.”

In Gear with NewEmployees and Projects

Nordex USA, Inc.

Nordex USA, Inc. officially opened in April of 2000 and has been riding high on

successful projects ever since.

With five wind parks scattered throughout the conti-

nent and more being discussed each week, the North

American branch office hums with activity as it serves cus-

tomers throughout the United States and Canada.

Since its debut over two years ago, physical expansion,

personnel growth, and increased sales have characterized

Nordex’ rapid development in North America. Located in Grand

Prairie, Texas, a suburb of Dallas, the office is responsible for

all sales and service activities for all of Nordex’ present and

future customers in North America. John Fedorko, President of

Nordex USA, says “We are genuinely excited to have new staff

members as part of the Nordex USA team. I really should say

“Nordex North America” as the market we serve is both the US

and Canada!” Fedorko commented specifically on the new staff,

“Klaus Obel, the new service manager comes to us with 18 years

of hands-on, practical field experience as both a project and

operations manager. His new assistant, Wolfgang Gloger, has

vast electro-mechanical experience in manufacturing and will

be a quick study for keeping our turbines’ availability optimized.

In addition, Steve Wieland recently joined us in the Sales

Department. Steve comes to Nordex from El Paso Energy, and

I believe his in-depth knowledge of the electricity business and

his electrical engineering degree will make him a great sales-

person. Finally, we have the best support staff around, with new

additions Patricia Lawrence as Office Manager and Marjorie

Asturias as Sales/Project Assistant supplementing the work that

Dorinda Matias does for us administratively in the Service

Department.”

Finally, effective January 1, 2003, Frede Jensen from Nordex

in Europe will join “Nordex North America” full time in Texas

as Director of Project Management/North America. Frede, an

electrical engineer, has vast experience in building wind farms

(he was Project Manager on Nordex’ Pincher Creek Project)

and will also help out with North American equipment pro-

curement. These employees in the office, as well as those

important service technicians in the field, keep Nordex USA

in the forefront of wind energy production in North America.

Nordex USA’s latest wind project in Minot, North Dakota,

was fully operational in November (see accompanying article).

Additional personnel to oversee the Minot park has resulted in

further expansion of the Nordex USA team as David Koapke

will be Nordex’ full time service technician for the wind projects

in North and South Dakota.

Nordex USA expects its project load to increase in the next

few years, particularly with the United States Production Tax

Credit set to expire in December of 2003 and the Canadian Wind

Power Production Incentive program lasting for another 5 years.

With this in mind, the Nordex USA team looks forward to excit-

ing and busy years ahead.

Nordex-Sponsored Kite Surf Trophy

Kite Surfing

What has kite surfing, also known as kite boarding or fly surfing, in common with

the wind energy business?

Late this summer, Nordex was one of the spon-

sors in the first European Kite Surf Trophy, and

Nordex CEO Dietmar Kestner explains this part-

nership by the following words: “With our commit-

ment we want to support this young, high-tech sport,

which makes intelligent and attractive use of wind

as a medium. In the course of this year, Nordex too

will be going offshore with its first prototype turbi-

ne. For this reason alone, we see parallels between

kite surfing and our business.”

Kite surfing is a new extreme water sport and a

combination of surfing and paragliding. This year, the

Trophy was held on Fehmarn in Germany from August

23 – 25, 2002, and Norderney from September 6 – 8,

2002, also in Germany. In 2003, the tour is to be ex-

tended. Additional events are planned in Poland and

Spain. Says Kestner: “As a global company, this in-

ternationalisation of the Trophy is very much in our

interest. We would be pleased if kite surfing were to

spread as fast as the use of wind energy.”

The Return of Don Quixote

Tourism and Wind Energy

Are the German coasts facing a dilemma?

T his is the question which came to the attention

of the Schleswig-Holstein Tourism Association.

On the one hand, the region depends more and more

on the development of wind energy – more than

15 % of the value added earned by the district of

Nordfriesland already come from “wind” – and on

the other hand, the landscape is also the capital of

this holiday region.

The photos are from the exiting days of the disciplines

“Kite Cross” and “Best Trick” in Fehmarn, Germany.


Many tourism managers feel that there is a conflict of

interests here. The association wanted more exact infor-

mation and commissioned a study from the NIT (Institute for

Tourism and Resort Research in Northern Europe) and the

University of Kiel in order to measure the effects of wind en-

ergy plants on tourism.

The results of this empirical study are clear: only 2 % of the

tourists mentioned wind turbines as a reason for not returning

to a resort for their holidays. The main negative factors named

were landfills, conventional power stations and tower buildings.

At the same time, the tourists who did feel disturbed assessed

their holidays as positively as the rest of those interviewed. The

long-term statistical analysis confirms this result, too. The re-

searchers compared the development of bed capacity utilis-

ation and the number of wind turbines on Fehmarn in the period

between 1981 and 1998. In spite of a 100 % increase in installa-

tions, capacity utilisation remained stable.

The study even comes to the conclusion that tourism could

make positive use of wind energy. A representative quote from

one of the interviewees: “Here something is being done for

the environment”. However, it is necessary to provide more

information on wind energy locally in order to convey this

environmental image to the guest. “Above all at locations with-

out experience of wind energy today unfortunately we often

experience the opposite. In order to remove exaggerated fears,

we have already organized wind park excursions for tourism

managers”, explains Nordex CEO Dietmar Kestner.

Black or white, flop or suc-

cess? The climate summit

in Johannesburg in Septem-

ber 2002 was assessed differ-

ently, depending on the view

taken. More than 60,000 del-

egates battled their way

through a vast range of differ-

ent topics. So the progress

made was bound to be modest.

And what was the outcome for

wind energy? One thing in par-

ticular: The announcement by

Russia and China that they in-

tend to subscribe to the Kyoto

protocol. This means that suf-

ficient countries have signed

the agreement to make it inter-

nationally effective. 55 % of the

CO2 producers are required

for this. Another important

achievement was the an-

nouncement by Gerhard

Schröder that a total of 500

million euros are to be made

available in the next 5 years

for the development of renew-

ables in the Third World. An

opportunity for Nordex, the

leading exporter in Germany.

More and more Germans

are in favor of develop-

– and not just since the latest

flood disaster. Sustainable

management and climate

protection have had a high

priority in public awareness for

a considerable time. And wind

energy – as the most econ-

omical way to generate “green

electricity”– has profited from

this particularly. A representa-

tive survey conducted by the

EMNID Research Institute has

now confirmed this. According

to this, 92% of the Germans

would welcome the increased

use of wind energy. Only 6.2%

were against it. Offshore use

was also favored by some

83 % of those interviewed.
