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

Feature

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

and e xpensive energy sources.

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.”

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: parnitzky@juwi.de

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.

Certifi ed Quality for the Operation of Wind and Solar Installations

Siegbert Goletz from the “System Certifi cation of Germanischer Lloyd SE” hands over the certifi cate to juwi Management’s

managing directors Rolf Heggen (l.) and Thomas Albrecht (r.).

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.
