Leading project developer and operations specialist for wind and solar plants

Competence and passion for renewable energy for 25 years

The juwi group is one of the leading experts for renewable energies. The renewable energy pioneer provides turnkey project development as well as many other services around the construction and operations of renewable energy plants. The business units of the juwi group are especially centered around projects regarding wind and solar energy.

Our Motivation: Enforcing renewable energy together economically and reliably with passion.

juwi was founded in the Rhineland-Palatinate in 1996 and today the company headquarters are located in Wörrstadt near Mainz. Since the end of 2014 the Mannheim-based MVV Energie AG is partner and company owner of the juwi group. The juwi group has approximately 850 employees as well as projects and subsidiaries on all continents.

To date juwi has developed more than 1,000 wind energy plants with a capacity of over 2,400 megawatts at 180 locations in the wind sector worldwide; in the solar sector more than 1,750 solar plants with a total capacity of over 3,100 megawatts. These energy plants together produce more than 9 billion kilowatt hours of electricity per year; which is equivalent to the annual power demand of 2.6 million households in Germany. To develop these energy projects, juwi has initiated an investment volume of around 9.5 billion euros over the last 25 years. 

An overview of the company history of juwi:

 

Facts and Figures
Year of Foundation: 1996 by Fred Jung (ju) and Matthias Willenbacher (wi)
Shareholders: 100% MVV Energie AG
Employees: approx. 850
Total Capacity: 5,500 Megawatt
Wind Plants: 1,030
PV-Plants: 1,750
Annual Yield: approx. 9.0 billion kWh
Investment Volume: approx. 9.5 billion Euro

In Mid 2016 the hand-over in the juwi management board takes place: After the resignation of Matthias Willenbacher from the management board in 2015 his co-founder Fred Jung joins the supervisory board in 2016. Michael Class becomes the new CEO. At the end of 2018, the previous majority owner, Mannheim-based MVV Energie AG takes over all shares in juwi.

In 2016 juwi realises its largest solar plant to date in company history: The 86 MW Sonnedix Prieska solar plant in South Africa. In 2018, a 135-megawatt solar project in India breaks this company record. juwi also sets new standards in Australia where the largest solar off-grid project in the world is built in the Australian outback. The 10.6 MW solar plant, which is built to supply power for a mine, also holds a 6 MW battery storage. Many more utility-scale solar plants are realised in the US, South-East-Asia, Japan and in Turkey.

In Germany, juwi initially focuses on the development of wind farms. The company establishes itself as one of the leading project developers in Germany and realises small- and large-scale wind farms all across the country. Shortly after the turn of the year 2016/2017 juwi exceeds the threshold of 2,000 MW of installed wind energy capacity. In 2019 juwi reaches another important milestone and builds its 1,000 wind turbine at the wind farm in Mohlis (Thuringia). With the construction of two solar plants in Brandenburg, juwi also re-enters the German solar business.

Additionally, the operations and maintenance business plays an increasingly prominent role. With the state-of-the-art control room, a 24/7 service and a volume of globally around 3,000 megawatts of wind and solar energy under surveillance, juwi is one of the big players in the field of technical and business operations.

The political framework in the home market Germany and in many other European countries deteriorates distinctly. After the reform of the German Renewable Energies Act in 2012, the German solar market collapses. juwi reacts by restructuring the company and dissociates from marginal businesses in the years to follow: The company ends its B2C, biogas and wood pellet business as well as the development of components. Instead, juwi concentrates on the development and construction of wind- and solar farms and their operation and maintenance. By the end of 2014, Mannheim energy supplier MVV Energie AG invests in the juwi Group. This partnership stabilises juwi sustainably and offers new perspectives for the future.

A reorientation is also conducted on an international level. Subsidiaries in Europe and Central America are closed, while at the same time business activities in the Asia-Pacific region are increased in Japan, Thailand, on the Philippines, in Australia and the APAC headquarters in Singapore. New business activities are also launched in Dubai and Turkey. In Germany, juwi consolidates its position as one of the leading developers of wind farms and realises numerous parks – among them the largest wind farm in southwestern Germany in Kirchberg (Hunsrück region).

Internationally, juwi realises numerous large-scale solar projects in 2015, among others in the US, India, Japan and Southeast Asia. Near Prieska in South Africa, the company starts with the construction of a 86-megawatt solar plant - the largest solar plant in the history of the company to date.

An era of enormous expansion begins for juwi. By the end of 2010, the number of employees increases to more than 1,000. In 2008, the company moves to its new headquarters in Wörrstadt, which has to be extended by a second building soon after. The expansion trend is also persistent internationally: activities are launched in Poland, the Czech Republic, Greece, South Africa and India. In 2009, juwi builds a 50-megawatt wind farm in Costa Rica, the largest wind farm in Central America to date. In the US, a 60-megawatt park is erected in Nebraska. In Germany, juwi increasingly builds large parks at complex sites, often in woodlands. In the solar business, the company also enters new dimensions.

In 2006, juwi builds solar plants with a total capacity of 12 megawatts, in 2009 one single park exceeds this capacity many times over: On a former military training area, juwi builds the third largest solar farm worldwide to date with 53 megawatts. Additionally, the company begins to enter new business areas: Several biogas and wood pellet plants are built and juwi begins to work on electromobility. Moreover, juwi starts to carry out repowering in the wind sector. Here smaller, older turbines are replaced by new and far more efficient ones.An era of enormous expansion begins for juwi.

juwi develops its solar activities to become a second and important area of business. In 2005, several free-field solar plants with a total capacity of approximately 3.5 megawatts are installed. Furthermore, a series of rooftop solar plants are installed. Among them the solar plants installed on the state theatre of Mainz in 2001 and the rooftop plant installed on the stadium of the former German national football league player Mainz at the Bruchweg in 2005. At the same time, juwi develops its position as one of the leading specialists for wind energy onshore. In 2002, the company installs its 100th wind turbine. In the same year, the pilot project "energy landscape Morbach" in the Hunsrück region is launched with 14 wind turbines and solar cells with a total capacity of 500 kilowatts. juwi also commences its activities abroad. In the Breton village of Plouguin, in the north-west of the French seaport Brest, juwi installs its first wind farm abroad in 2004. Further business follows in the US, Spain and Costa Rica.

Independently from one another, physicist Matthias Willenbacher and agricultural economist Fred Jung began to measure wind conditions at their parents' farms in the Palatinate. After their first meeting, the two men decide to work together and, on 4th December 1996, they found the company Jung & Willenbacher Windenergie GmbH, later re-branded juwi GmbH. In 1997, the first wind turbines are installed at Schneebergerhof (Donnersberg region) and three further plants in Spiesheim (Alzey-Worms) follow. Only two years later, juwi builds the largest wind farm to date in South Germany. Near Alzey in Flomborn, Steten and Ilbesheim the young enterprise installs 19 wind turbines with a total capacity of 19.1 megawatts. In 1999, juwi enters the solar business and realises its first large solar plant in the following year, in Kirchheimbolanden.
