this summer is chock-full of exciting major sporting events: After a number of continental championships, athletes
from across the globe are currently assembling in London to compete in the Olympic Games. The spirit of the Olympics
– the most important thing is taking part – may be enough for athletic competitions. As a guiding principle for global
development, however, it isn’t very good.
This makes the results of the United Nations conference in Rio de Janeiro even a bit more disappointing. The “Rio+20”
conference, which took place exactly 20 years after the UN World Summit on Sustainable Development at the same loca-
tion, was not able to generate the atmosphere of change that was so desperately needed. Instead, once again we were
presented with non-binding declarations of intent, the contents of which were labeled “a step in the right direction”.
It is therefore even more important that so many citizens, local politicians and entrepreneurs are so devoted to clean
energy generation with added value for local communities thanks to tax and leasing revenues as well as new regional
job opportunities. Allowing this positive trend to end suddenly would be a fatal move. Peter Altmaier, Germany’s new
Federal Environment Minister, is therefore faced with the challenge of providing a political framework for general
public’s demands for a livable environment – no small task.
Naturally we are also facing this challenge in an energy market that is constantly shifting. With the juwi Home Power
battery storage system, we have created a product for the end-customer that allows solar system owners to
use cost-effi cient solar energy from their own roofs, even at night. You can read more about this on page 8 of this
edition. If you would like to experience this intelligent and powerful battery storage system in person, come visit us
on August 18, 2012, at 1 pm in Wörrstadt. At our open house day, we will be presenting products and services for your
own personal energy revolution.
We hope that you enjoy reading this edition of juwinews. And, as you may have noticed from the photo, there are now
four of us on the executive board of the juwi group. Find out more on page 22.

A Dizzying Adventure at the Wind Festival in Hunsrück
Corina Schell treated herself to a unique thrill ride in mid-May at the
Wind Festival in Kirchberg. In front of approximately 1,000 guests,
the juwi employee was lowered like a spider on a thin thread from
the top of a wind turbine gondola, at a height of 138 meters, along
with Erik Neuhofen from the Ingelheim Fire Department. The event
was the high point of the wind farm inauguration celebration in
Hunsrück. juwi and the utility company Energieversorgung Offen-
bach AG (EVO) have constructed 23 Enercon E-82 wind turbines
at this location. With an annual energy production of approximately
125 million kWh, Kirchberg is the most powerful wind farm in
southwest Germany. You can read an article about how Corina
Schell is earning a degree alongside work on page 21 of this

Energy Revolution with Wind Farm, Solar Free-Field Installation and Carports
From an eagle’s eye view, the 1,824 photovoltaic modules look like the grandstand roof
of a soccer arena: At the end of 2011, juwi commissioned a large number of solar car-
ports with a total capacity of 420 kW at the Alemannia Waldalgesheim sports club’s
stadium. This means that the existing parking spaces feature one more attraction:
Dry and shady places for the stadium’s visitors to park their cars. The small town near
Bingen on the Rhine river recognized the advantages of renewable energy very early
on: A 2.5 megawatt free-fi eld solar installation located east of highway A61 has been
producing clean solar energy since 2008. In May 2011, juwi connected a wind farm with
four Enercon E-82 wind turbines to the grid just few kilometers to the north, and an
additional installation is currently under construction. Picture: Manfred Czerwinski

Energy Is at HomeSolar energy from rooftop installations and wood fuels produced locally

When the transmission system operators provided German Chan-
cellor Angela Merkel with their plan for expanding the German
power grid in May, the astronomically high price of 32 billion euros
loomed large in the headlines. That was how much money the plans
for the energy revolution were going to gobble up. But this number
is nothing to worry about – for those who can generate energy
close to consumers and make profi table use of it, rather than pur-
chasing expensive energy from distant off shore wind farms on the
North Sea. For the increasing numbers of photovoltaic system
owners, producing their own energy is becoming more and more
attractive, because the energy from their rooftop installations will
soon be cheaper than the energy from their wall sockets. Grid parity
will usher in a new age in supplying energy: The gap is closing be-
tween generation and consumption, and that saves money.
Storing solar energy for nighttime use
“Power generated from rooftop systems is already competitive,”
confi rms Philipp Schröder, head of Sales & Acquisition for rooftop
installations at juwi Solar, “and juwi off ers a strong line of products,
as well as a great deal of experience and passion, to help our cus-
tomers to take advantage of the considerable savings of solar
energy as compared to energy from the grid.” Many photovoltaic
system operators are already profi ting from this shift in prices by
not only using their own solar energy during the day, but also stor-
ing it for use at night with juwi Home Power, the intelligent storage
system for residential buildings and small commercial buildings.
Stefan Biebel, a resident of Rossdorf in the district of Darmstadt in
Hesse, has one of these battery storage units in the basement of his
single-family home. “Energy is becoming more and more expensive
0908
GAS TANK
every year,” says Biebel, explaining why he did more than just in-
stall solar modules (3.7 kWp, 16 square meters) on his roof in 2011.
In order to increase the amount of self-produced energy that would
be available for consumption, he connected the energy storage
unit, which has a peak output of 8.4 kW and is roughly the size of
a refrigerator, to his PV system. “It allows me to divide up the en-
ergy, which is great,” Biebel explains. “During the day I store up the
solar energy so that I can use it even when there’s no sun.” In the
fi rst half of the year, Biebel used 650 kWh of clean solar energy from
the roof of his home: energy which he would otherwise have had to
get from the grid. He’s excited about his own personal energy revo-
lution: “In this way, I can do my part to reduce the market power of
the large energy supply companies.” The homeowner says that the
investment will have paid for itself after 13 years.
At the end of 2011, Winfried Bayer, an entrepreneur from Alzey in
Rhinehesse, installed a photovoltaic system on the roof of his car
dealership. This installation allowed him to kill two birds with one
stone, because he was able to pay for the necessary renovation of
the roof with the funds he received from EEG compensations. “The
key factor for me was that I would be able to recoup 100 percent of
the investment within 15 years,” says Bayer. At that time, the private
consumption model proved to be the most logical option: The building
requires the most energy during the day, so that’s when Bayer uses
energy directly from the roof. “I was interested to see whether this
would work,” Bayer remembers. “And it did.”
The Bayer car dealership uses the sun’s power mainly for its own consumption.
Stefan Biebel from Rossdorf near Darmstadt: “With the battery storage, I can use solar power even if there is no sun.”

Regenerative heat leads to yearly savings of 1,300 euros
Power isn’t the only thing that’s cheaper when it’s generated using
local resources; heat energy is also more cost-effi cient when raw
materials from the surrounding area are used. Jochem Schild, from
the small town of Weibern in the Eifel region of Germany, heats the
200 square meter living area of his single-family home with carbon-
neutral juwi wood pellets from the production facility in Morbach.
Six tons of these pellets pass through his furnace every year. He can
give you the concrete fi gures for the diff erence in price compared to
heating oil: around 1,300 euros a year. Schild bought his 102-year-old
house in 2005. The house was built using tuff , a porous volcanic rock.
Heating with oil was out of the question. He renovated the roof and
the windows, and installed a wood pellet furnace. “The additional
costs have paid for themselves over the years,” says Schild.
A number of juwi customers cut their heating costs with these
pellets, and not only in the sales region of Morbach in Hunsrück.
juwi’s pellet customers in the areas around its production facilities
in Langelsheim in the Harz region, Bad Arolsen in North Hesse, and
Dotternhausen in Swabian Jura heat their buildings with energy
from local regenerative raw materials. They get their energy with-
out requiring dangerous and expensive transport of raw materials.
In Bad Arolsen and Dotternhausen, juwi also produces wood bri-
quettes, in addition to pellets.

People heating their building with regenerative sources can
now also buy wood briquettes from juwi. In order to strengthen
sales in this area, juwi has taken over hardbriks GmbH from Bad
Mergentheim (Baden-Württemberg). The company is a leading
provider of oak, beech, and bark briquettes and has so far sold
them to private customers as well as kiln engineering. In the
future, hardbriks customers will be supplied with regional wood
products from the juwi locations Langelsheim, Dotternhausen,
Bad Arolsen and Morbach. juwi puts the focus on the regional
principle for the distribution of briquettes. Customers are sup-
plied from the four production plants located all over Germany
- in cooperation with the utility Stadtwerke Mainz - in order to
minimize the environmental impacts
from the transport to a large
extent. Bad Mergentheim
will be developed into
a sales and logistics
center.
juwi takes over supplier of wood briquettes
It is a warm summer’s day. A soft breeze wafts over a meadow,
which is dotted with wildfl owers. Insects buzz from fl ower to fl ower
while, somewhere in the background, above the tree tops of the
Hunsrück region, a number of wind turbines are rotating. This
peaceful atmosphere provides no indication of the confl ict that has
developed over a wind power project in a nearby forest.
At the beginning of March, juwi began the approved preliminary ac-
tivities for the construction of eight wind turbines in the Soonwald
mountain range near the small town of Ellern, between the Katzen-
kopf and Hochsteinchen mountains. The peaks of Hunsrück are ex-
tremely windy areas. Here, wind speeds are reached that are other-
wise only seen on the coast. At the same time, the area is the natural
habitat of wildcats and various species of bats. This caused local
conservation groups such as NABU (Naturschutzbund Deutschland
e.V.) and BUND (Friends of the Earth Germany) to spring into action
and resulted in organized protests by the conservationists.
However, juwi is one of the renewable energy developers that take
pains to balance the energy revolution with environmental protec-
tion. “We do our best to avoid encroaching on natural habitats
wherever possible, or at least to minimize the impact and create
ecological compensation areas,” explains Heike Bunse. Along with
her team, the juwi employee assesses locations in terms of eco-
logical conservation. Their work begins long before the actual
construction of a wind farm starts. Reports are written up evaluating
the population levels of endangered species. These reports mean
that bat roosts, for example, are excluded when selecting locations.
In Ellern, juwi had already performed a much more in-depth evalu-
ation of the area than is required by law. The areas that were
marked for clearance were selected so that the valuable old-growth
forests, which are the preferred habitat for many of the bats, remain
untouched. “And in order to be absolutely sure, we inspected every
individual tree a second time before we began clearing,” reports
juwi project manager Jens Baecker.
Reforestation improves forest stand
By the time the fi rst turbines start running by the end of the summer,
additional conservative measures will be put in place. In order to keep
the bats from colliding with the rotor blades, the turbines will be shut
off for specifi c periods of time during the night. In addition, reforesta-
tion measures are customary for forest projects like the one in Ellern.
“In Soonwald, one of our measures is ecological reforestation,
thereby creating stable, high-quality forested areas,” explains juwi
employee Anna Adelt. This isn’t an empty promise. “Compensation
measures often lead to an improvement in the animals’ habitats and
can even lead to an increase in biodiversity,” confi rms Peter Ahmels
from the Deutsche Umwelthilfe e.V. in Berlin.

Windmills surrounded by reeds, dunes and beach scenery. The third
juwi wind farm in Poland is located only a few kilometers from the
Baltic coast. Since the beginning of May, fi ve Vestas turbines turn
in Roby in West Pomerania, about 100 kilometers northeast of
Stettin. With a total of 4.25 megawatts they produce enough energy
to supply 3,400 households. juwi odnawialna Energia, the Polish
subsidiary of juwi, built the wind farm as a so-called EPC project for
an investor. It is owned by PSW Sp. z o.o, the Polska Sila Wiatru.
juwi Poland had already built two EPC projects in 2011 in western
Poland and is currently implementing other projects in the east of
the country. In Popowo in Western Pommerania juwi is construct-
ing a wind farm with a total output of 2.4 megawatt and in Chojny
in Greater Poland two wind turbines with a total of four megawatt
are being built.
The 4 megawatts (MW) wind project at Whynotts Settlement, in the
Bridgewater area, is being jointly developed by juwi Wind Canada
and Community Wind Farms Inc. Once constructed, the project will
generate enough power for approximately 1,200 homes a year. The
project will be funded through the Community Feed-In Tariff Pro-
gram by the Nova Scotia Department of Energy. “Opportunities in
renewable energy are important for us today and for our future.
Expanding the knowledge on what we can do with our natural re-
sources can help shape how our communities live and work for
years to come,” said Chief Gerard Julian, Co-Chair of the Assembly
of Nova Scotia Mi'kmaq Chiefs. “The Whynotts project will begin
to assist in addressing how the Mi'kmaq will be a viable and long
term player in the renewable energy sector,” he added. “As project
owners, we will be able to deliver a Mi'kmaq benefi ts program,
designed and delivered by the Mi'kmaq, for the Mi'kmaq.” Whyn-
otts also aff ords the Assembly the opportunity to educate their
youth in the science of renewable energy and they will utilize the
project as a free standing science exhibit. In addition to the Whyn-
otts wind farm, juwi is also working on fi ve additional wind projects
with First Nations.

Worthington is a small city that lies in southwest Minnesota. The
city’s population totals approximately 11,000 inhabitants. The state
of Iowa is located 40 kilometers further south. This region plays an
especially important role for juwi Wind LLC. After the successes
with Flatwater wind farm, this is where the very fi rst juwi Wind
wind park will soon be built.
juwi is installing 15 REpower turbines with a total capacity of 30
megawatts. Turbines and nacelle will be installed in September.
Component delivery is a logistical masterpiece – nacelles are de-
livered from Husum, Germany, rotor blades from Little Rock, Arkan-
sas, and the steel towers from North Dakota.
Renewable energies in the US is actually an issue that each state
must address individually. Legislation in Minnesota requires that
5 percent of the fi nancing for wind parks come from local stakehold-
ers. This also holds true for the project north of Worthington. “In
addition to juwi, the board of directors of Community Wind South
and the owners of the land on which the wind turbines are located
or under which the cables run are also stakeholders in the wind
park,” says Aaron Peterson, juwi Wind LLC project manager.
Wind for WorthingtonIn the Southwest of Minnesota, juwi Wind LLC has developed a wind farm with the highest turbines in the state. Construction has started in May.

The juwi group’s work in South America will soon bear its first fruits
– and we mean that literally. In the sunny Coquimbo Region in
Northern Chile, juwi and the Chilean engineering firm Kaltemp are
jointly creating one of the country’s largest solar power plants.
Around 5,000 polycrystalline modules are spread out across an
area of almost two hectares to supply energy to the irrigation
system of a nearby clementine and avocado plantation. Construc-
tion started in June on the solar power plant with a capacity of over
1,200 kilowatts.
juwi has also secured a contract for another solar project in the Co-
quimbo Region: the mining company BHP Billiton wants to construct
a free-fi eld installation with a capacity of one megawatt in the middle
of the Atacama Desert to supply energy to the world’s highest-alti-
tude copper mine – at 3,200 meters above sea level. The mine is also
one of the world’s largest. The solar power plant will have to with-
stand earth quakes as well as extreme weather patterns such as
sand storms and gusts.
For juwi, both projects are a huge opportunity in an important mar-
ket. “Chile has excellent conditions for solar energy. We not only
have high levels of solar radiation but also outstanding wind condi-
tions,” comments Diego Lobo-Guerrero Rodríguez, project coordina-
tor for Latin America. “Chile also has excellent conditions for wind
energy, is a politically stable country and is extremely open to re-
newable energies.”

the mountains. Both plants were created in
cooperation with the University of Anta-
fogasta and use thin-fi lm as well as poly-

In Elmenhorst near Hamburg, juwi Solar GmbH has connected Schleswig-Holstein’s
second largest free-fi eld solar park to the grid. By the end of June, over 103,500 poly-
crystalline modules had been laid on the approximately 60 hectare plot of land, which
once housed German Army barracks. The solar power plant has been producing green
electricity since July. “I’m delighted that we were able to commission the power plant
as planned. This would not have been possible without the outstanding work and coop-
eration between all the involved departments,” stated the project manager Tilman
Rückert.
The solar park has a nominal output of around 24 megawatts and produces an impres-
sive 23 million kilowatt hours of clean solar power annually. This corresponds to the
annual power consumption of more than 7,700 households. However, the solar power
plant does not only supply clean electricity, it also prevents the emission of almost
15,000 tons of the environmentally-damaging greenhouse gas CO2 per year. Once
complete, it will be operated by RIO Energie GmbH & Co. KG, a joint venture between
the Stadtwerke Mainz AG and the juwi group.
Gerd Krämer, District Administrator for the Duchy of Lauenburg, also regards the solar
park as an important step forward for the region as part of the energy revolution and
a reason for celebration: “The district assembly has been a strong supporter of the
energy revolution in our region. I am even more delighted that we are creating this solar
park with juwi. By building the solar park in Elmenhorst, we are paving the way for
renewable energies.” Krämer emphasizes that, despite the tight schedule, all offi cial
authorizations were issued quickly.
Herbert Muders, managing director of juwi Solar Germany, also expresses his grati-
tude to everyone involved at the regional level for their quick and highly focused
support: “Without this support, it would not have been possible to implement a
project of this scale on schedule.”

Henderson, Nevada. The new Ethel M® factory solar garden fea-
tures 2,112 ground-mounted solar panels on 4.4 acres, and is the
largest solar installation by a food manufacturer in Nevada. All of
the power generated by the solar power plant will be consumed by
the Mars Chocolate factory that produces the Ethel M® and Ethel’s
brand chocolates.
The installation generates 1,258 megawatt hours of zero-emission
electricity each year, off setting 825 metric tons of greenhouse gas.
“This newest solar garden moves us closer to our goals of eliminating
our carbon footprint at our sites by 2040 and using 100 percent re-
newable energy,” said Mike Wittman, Mars vice president of sales.
The project’s completion was commemorated in February with
a ribbon-cutting event attended by state and local government of-
fi cials, executives from NV Energy, juwi solar Inc., and Mars Choco-
late North America. “Turning one of the desert’s greatest assets
into energy is in complete alignment with Mars’ Principles in Action
and our core business values,” said Mack Phillips, site director of
the Henderson plant, at the opening ceremony.
Two years ago, JSI built a 2-MW solar power system for Mars Choco-
late North America’s headquarters in Hackettstown, New Jersey.
“We are proud to play a role in advancing environmental and sustain-
ability goals through replacing the grid’s brown power with green
power generated onsite,” said Michael Martin, CEO of juwi solar Inc.

Blue fl ags fl ap in the wind in front of the headquarters of the Stadt-
werke Kiel. The company slogan, “Your energy is here”, is emblazoned
on the fl ags in the form of numerous sails. For the Kiel-based company,
water is a ubiquitous element, even in terms of energy supply.
“We have been utilizing renewable energy for over a century at our
two hydropower plants in Raisdorf on the Schwentine River in
Schleswig-Holstein,” says Roger Mayer, managing director of
24seven GmbH, the Stadtwerke Kiel’s department for grid and power
generation. The northern Germans also built the fi rst wind farm in
Schleswig-Holstein over 18 years ago in Friedrichskoog, together
with other local utilities. The wind farm consists of 8 turbines with
a total output of approximately 2 megawatts. In the last few years
the company has been stepping up its eff orts in the fi eld of renew-
able energy, and one of the ways they are doing this is by working
together with juwi. “With the joint venture 24seven Nordwatt
GmbH, we’re investing even more in renewable energy in order to
remain future-oriented. Regenerative systems are going to play
a pivotal role in energy supply in the future,” explains Mayer, who
has also been the managing director of the joint venture since 2010.
24seven Nordwatt GmbH is primarily focused on wind and solar
energy. Two employees, together with employees from juwi,
are currently securing a number of sites for wind energy systems.
A 500 kWp solar system was recently constructed on the roof of a
shipping company in Bad Bramstedt and additional solar projects
are currently in the pipeline. The Kiel Stadtwerke was already
aware that juwi is a reliable business partner. “juwi was also
interested in working with us because we have deep ties to the
region and are well known locally, and also because we have good
contacts within the communities,” says Mayer. One of these useful
contacts is with the state government of Schleswig-Holstein.
During his tenure as the mayor of Kiel, minister-president Torsten
Albig served for a number of years on the board of directors of the
Kiel Stadtwerke and supports the expansion of renewables.
The creation and expansion of decentralized energy supply struc-
tures will result in new challenges for the public utility company.
Therefore, they are interested in gaining experience and expert
knowledge in the areas of project planning and fi nancing in the fu-
ture, alongside technology, installation, operation and mainte-
nance. This change in direction also changes the company’s rela-
tionship with its customers. Stadtwerke Kiel wants to off er new
services and new solutions. By the end of this process, the energy
supplier will turn into an energy liaison.

Less than half an hour’s drive from Leipzig, the Waldpolenz Energy Park, a huge solar power
plant, is located on the site of a former Soviet army military airfi eld. The juwi group and the
city of Brandis successfully completed this project in 2006. At that time, however, there
were already even more ideas for the potential future use of the 142 hectare site: It was to
be used as a model project for supplying the region with 100 percent renewable energy.
The two partners have now embarked upon an important project in this regard: At the start
of the year, construction began on a biogas feed-in plant right next to the free-fi eld solar
installation, which was expanded in fall 2011. This type of production site is still rare
in Germany, with only around 70 of the country’s approx. 7,400 biogas plants currently
using this technology. Unlike conventional biogas plants, this plant type will not be used to
generate electricity. Instead, it will gener-
ate high-grade biogas in natural gas quality
which can be fed into the natural gas grid
and stored.
To achieve this, a special procedure is used
to separate the produced biogas from car-
bon dioxide and other gas compounds. The
cleaned biogas then consists of up to
96 percent methane and can be fed into
MITGAS Verteilnetz GmbH’s natural gas
grid. As the general contractor, juwi is re-
sponsible for planning, logistics and con-
struction management during the project;
Schmack Biogas GmbH will supply the
entire plant.
Schmack managing director Dr. Tino
Weber describes the benefits of this type
of plant: “With its horizontal fermenters
and highly-efficient agitators, our technol-
ogy ensures optimum fermentation at all
times.” This also makes it possible to eas-
ily process larger volumes of grass, a wide
range of plants and even agricultural
waste products.
But what would the most sophisticated bio-
gas plant be without substrates? In this re-
gard, juwi closely focuses on sustainability
and regionality. The plant will be supplied
with substrates (approx. 55,000 metric tons
per year) by regional farmers in the form of
regenerative raw materials, such as corn,
whole plant silage, and sugar beets, as well
as natural manure. The fi elds in which the

juwi is also currently building a biogas plant in Göllheim in Rheinland Palati-
nate. What makes this so special is that instead of a conventional green
power plant, juwi is building a complete energy park, which will generate not
only bioenergy, but also solar power and wind power. The biogas plant will
remain the heart of the park. Its fermenters will process corn, sugar beets,
millet and even grass cuttings from the region in order to generate biogas.
Contrary to the usual practice in combined heat and power plants, this gas
will not be converted into electricity and heat. Instead, its CO2 content will
be removed and the gas will be fed into the local natural gas grid as pure
methane. The separated CO2 will no longer be simply released into the air but
instead used as a raw material for producing dry ice. A revolutionary concept
for storing excess energy makes the Göllheim Energy Park a true landmark
project. In just a few years’ time, renewable energy will be ‘conserved’ here
– not by using expensive batteries or complicated pumped water storage
systems, but through the use of the ‘power-to-gas’ method.
regenerative raw materials are grown are
located no more than 15 to 20 kilometers
from the plant. juwi will organize collective
transportation for deliveries to keep the
traffi c volume as low as possible for the
surrounding communities.
“Our 100% vision is gradually becoming
a reality in the Waldpolenz Energy Park,”
says juwi branch manager Günter Vallentin,
excited about the current project. “With
the access road to the Energy Park, which
will be built at the start of next year, many
people here in the region will become
aware of our plants.”

Green Buildings
The principle aim for all new buildings sponsored by the city of
Frankfurt on the Main is to save energy. Where possible, the new
buildings should be constructed in the resource-conserving pas-
sive house style. Thanks to juwi Green Buildings’ expertise, the
banking metropolis has taken a huge step towards achieving this
aim with a central project for new buildings.
In Frankfurt-Riedberg, an energy-effi cient building complex includ-
ing an elementary school for more than 400 children, a dual-fi eld
sports hall, an indoor swimming pool and a day-care facility is being
built on an over 18,000 square meter plot in Graf-von-Stauff enberg-
Allee. The project, which will make the city less dependent on in-
creasingly expensive energy imports starting in spring 2014, will
cost almost 35 million euros.
The specialists at juwi Green Buildings thoroughly impressed the
Frankfurt offi cials with their resource-conserving, energy-effi cient
construction concept. In line with this concept, the complex will be
heated primarily by the heat generated within the building, comple-
mented by the excellent insulation provided by the triple-glazed
windows. The remaining energy requirements will be met by a local
district heating grid. Hot water will be provided year-round by
a solar-thermal system. “This solution has proven to be particularly
ideal for the great fl uctuations in consumption in the sports hall and
the swimming pool,” states Ralf Ratanski, managing director of juwi
Green Buildings. Even rain water does not go to waste in the new
building. It is collected, fi ltered and used in the toilets. “This saves
drinking water and reduces sewage charges,” comments Dominik
Benner, joint managing director of juwi Green Buildings.

2120Career
Whether participating in cooperative education programs, earning
a degree while working or studying privately, independent of their
employers, there are numerous options available to people who
want to further their qualifi cations by pursuing a master’s degree.
At juwi, Corina Schell and Manuel Amberger have opted for the
second approach – earning a master’s degree alongside work. This
means that they study at a university of applied sciences on certain
days of the week and work for juwi the rest of the time.
Manuel Amberger recently began his degree at the Haus der
Technik, a technical university in Essen. This means that every
other Friday, he fi nishes work at 1 PM. Finishes work? Not quite!
After leaving juwi, Manuel drives to Essen, where he attends lec-
tures in the afternoon and on Saturdays. After four semesters, he
will graduate with a Master of Science in Energy Economics. The
26-year-old has been a project manager in the Research & Develop-
ment department since September 2011. This role includes dealing
with the direct marketing of renewable energies. Manuel has al-
ways known that he wanted to add to his qualifi cations and obtain
a master’s degree: “The master’s degree helps me enhance my
previous knowledge. The ability to complete this as an extra
occupational degree makes me fi nancially independent. However,
I fi nd that the greatest advantage is being able to study and gain
valuable professional experience at the same time.”
Corina Schell started her Management degree at FH Mainz Uni-
versity of Applied Sciences in February. Since then, the project
manager has only been working in Wörrstadt three times a week.
“I have to go to the university on Tuesdays and Saturdays; I spend
Mondays studying or preparing,” explains the 27-year-old. “It was
important to reduce my working hours so I could meet the de-
mands of both my studies and my career. I am grateful to my col-
leagues and supervisors for making this possible by providing me
with such great support.” The degree combines elements of
marketing, communication, controlling and finance. “An exciting
combination, which is also in demand at juwi.”
juwi supports employees who want to earn a master’s degree. “If
an employee has decided to pursue a degree and arranged this
with his or her manager, we enter into cooperation agreements
with the university,” explains Bodo Parnitzky, who provides the
master’s students with advice on behalf of the HR department.
juwi already offers a successful cooperative bachelor’s degree
program with even closer links between the company and the
university.
If you have any questions about earning a degree alongside work,
please do not hesitate to contact Bodo Parnitzky: [email protected]

in Mainz and Essen.
Between Seminars, Lectures and juwiHow juwi employees successfully combine their master’s studies and everyday professional lives
Since July, juwi has a fourth board member:
45-year-old Martin Winter has taken on the
role of CFO. He brings with him 17 years of
experience from the fi nancial sector, and
a view of juwi that is anything but ordinary.
Last summer, the fi nance expert and sports
pilot fl ew his gyrocopter over the rolling
Rhine-Hessian countryside. Below him –
between the wind turbines and the solar
fi eld – lay juwi headquarters. At the time,
this still comprised two buildings; currently,
juwi employees are moving into a third build-
ing. juwi’s rapid growth in recent years is
one of the reasons Winter has joined the
company. The board’s responsibilities have
grown, and so has its need for more mem-
bers to help fulfi ll them.
Over the last two years, the business gradu-
ate already had close ties to the company’s
development. As a partner at the consulting
fi rm Schwabe, Ley und Greiner, he has ad-
vised juwi on many fi nancial matters. He
helped develop the company’s liquidity plan
and designed the treasury concept. “The
company has a fantastic fi nancial charter.
I wrote it myself,” he says with a wink. Be-
hind this casual remark, there is also an im-
portant insight: Martin Winter knows what
he is getting into – and not just from a pro-
fessional perspective. “juwi’s atmosphere
and fl air are particularly attractive.”
In his eleven-and-a-half years as a consul-
tant, Winter has worked with many diff erent
companies – from DAX-listed groups to clas-
sic mid-sized businesses. He began his ca-
reer in the construction sector. He was re-
sponsible for the commercial auditing of
major projects in Asia for the Philipp Holz-
mann group. At 31, he was the head of inter-
nal auditing for the group. He later became
the head of fi nance for the construction
company SÜBA. In short, his professional
life can be summed up with four terms:
banking training, business degree, construc-
tion industry and consultancy career.
Of course, as a person, Martin Winter is far
more complex. He refers to himself as
a child of the Rhine-Main region. He was
born in Off enbach and is still based in the
greater Frankfurt area. He is a fan of the
Eintracht Frankfurt soccer club and he often
plays the church organ in his local parish on
Sundays. He studied in Paris for a year and
a half in the 1990s, and speaks fl uent French.
On holiday, he and his wife regularly ride
their motorbikes to rather exotic corners of
the world. And then there is his hobby as
a sports pilot. Winter’s personality truly has
many sides.

Martin Winter is the fourth member of the juwi Executive board.
The Fourth Member of the TeamSince July 1, juwi has a fourth board member.
With the acquisition of a new subsidiary in Fürstenwalde/Spree, the juwi group
is strengthening its commitment to the German state of Brandenburg. Within
this region, juwi is planning installations in the wind, solar and bioenergy
sectors. “Brandenburg is a state that is full of energy. Together with citizens
and communities we will make the enery transition a success,” emphasizes
juwi CEO Matthias Willenbacher. “Fürstenwalde wants to generate more
electricity from renewable energy in the future. This is another reason why I
am delighted to welcome juwi to Fürstenwalde,” Mayor Hans-Ulrich Hengst
said at the offi ce opening. juwi is currently creating a 1.1 MW free-fi eld solar
park in Fürstenwalde.

An Impressive Week for juwi
In April, juwi was able to add three new awards to its collection
within the space of just a single week. It all began at a historic site:
In the former plenary hall of the German Federal Parliament in Bonn,
the Association for the Promotion of the Concept of Sustainability
(Verein zur Förderung des Sustainability-Gedankens) presented the
juwi group with an award in the “Most Sustainable Company”
category. Just a few days later, the “Germany - Land of Ideas” ini-
tiative presented juwi with the “Selected Landmark 2012” award
for the wind turbine towers installed near company headquarters
in Wörrstadt. Within the scope of the joint venture “Advanced
Tower Systems” (ATS), juwi develops steel and concrete towers
that make domestic wind energy even more cost eff ective. At the
end of the week, the juwi group received the “Industry Award 2012”
at the Hanover Messe during the Night of Innovations. Huber Verlag
für Neue Medien (Huber Publishing House for New Media) pre-
sented the juwi group with the award in the “Energy and Environ-
ment” category for its commitment to ecological and resource-
conserving construction.

juwi Management GmbH has been fully certifi ed in accordance with
ISO 9001 since February. This strengthens its market position and
reinforces its claim to ensure dependable quality management
during the technical and commercial operation of regenerative
energy systems. The Germanischer Lloyd SE - Systems Certifi ca-
tion audit offi ce certifi ed all of the company’s departments in less
than two years. “The optimization of numerous processes within
the scope of the certifi cation has enabled us to vastly increase ef-
fi ciency,” juwi Management GmbH’s managing directors Thomas
Albrecht and Rolf Heggen report. Despite little change in the num-
ber of employees over the last few months, the service provider is
able to off er even better quality management for a continually
growing number of operating companies, as well as for wind and
solar parks.

Guests and friends of the juwi group will come together to truly ex-
perience energy on August 18, 2012. In keeping with the theme of
“experiencing energy”, juwi is inviting citizens from near and far,
business partners, and all employees and their families to an open
house at the company headquarters in Wörrstadt. The guests will
be able to fi nd out all about the juwi group’s current energy projects
and see the new central building for the fi rst time. The new building
off ers approximately 650 additional job openings and the new caf-
eteria off ers far more space than its predecessor. Another highlight
of the new building is its open design concept, which has replaced
the classic cubicle set up of the old buildings. The open house in-
cludes not only a stage show in the new cafeteria, but also tours of
the new central building, entertainment for children, as well as juwi’s
traditional soccer tournament, the juwi Cup.
