Dear friends of the juwi group, 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 location, 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-efficient 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 Hunsr端ck 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 Hunsr端ck. juwi and the utility company Energieversorgung Offenbach 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.

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 carports 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-field 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.

Energy Is at Home Solar energy from rooftop installations and wood fuels produced locally allow homeowners and companies to become independent of conventional and expensive energy sources.

When the transmission system operators provided German Chancellor 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 between 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 customers 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 storing 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

In Record Time juwi constructs a 24-megawatt free-field solar park in Elmenhorst near Hamburg
In Elmenhorst near Hamburg, juwi Solar GmbH has connected Schleswig-Holstein’s second largest free-field solar park to the grid. By the end of June, over 103,500 polycrystalline 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 cooperation 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 impressive 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 CO 2 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 official authorizations were issued quickly. Herbert Muders, managing director of juwi Solar Germany, also expresses his gratitude 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.”

Experience Energy at juwi Headquarters use Open Ho st 18, on Augu 2012
Guests and friends of the juwi group will come together to truly experience 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 find out all about the juwi group’s current energy projects and see the new central building for the first time. The new building off ers approximately 650 additional job openings and the new cafeteria 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 includes 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.
