With almost 25 years of experience, juwi is one of the pioneers in the field of renewable energies. Find out more about our history.

2016 - 2020 Worldwide energy transition

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 to the Supervisory Board in 2016. Michael Class becomes the new CEO. At the end of 2018, the previous majority owner, Mannheimer MVV Energie AG, took over all shares in juwi.

In 2016 juwi realizes its largest solar park so far: The 86 MW Sonnedix Prieska solar park in South Africa. In 2018, a 135 megawatt solar project in India broke this record.In the Australian outback, the company sets another milestone: the largest solar off-grid project in the world. The 10.6MW solar-diesel-hybrid-system with a 6MW battery storage provides electricity to a copper mine. Many more utility scale solar plants are realized in the USA, South-East-Asia, Japan and Turkey.

In Germany, juwi focuses on the development of wind farms. The company establishes itself as one of the leading project developers in the field of wind onshore and realizes wind farms all around the country. Right after the turn of the year 2016/2017 juwi exceeds the benchmark of 2,000 MW of installed wind energy capacity. In 2019 juwi reached another important milestone and built its 1,000 wind turbine with the wind farm in Mohlis (Thuringia). With the construction of two solar parks in Brandenburg, juwi is also re-entering the German solar business.

Additionally, the Operations & 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 Megawatt of wind and solar energy under surveillance juwi is one of the big players in the field of technical and business operations.

2011 - 2015 Focus on Core Business

The political framework in Germany and abroad deteriorate 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 stops its B2C, biogas, wood pellet businesses 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 takes a 50.1 per cent share of the juwi Group. Today MVV Energy AG is the sole Shareholder of the juwi group. This partnership stabilizes juwi lastingly and offers new perspectives for the future.

A reorientation is also conducted on an international level. Subsidiaries in Europe and Central America are closed, at the same time, business activities are increased in Japan, Thailand, on the Philippines, in Australia and in Singapore. New subsidiaries are also opened 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.

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 park - the largest one in the company's history.

2006 - 2010 Enormous Expansion

juwi faces an era of enormous expansion. By the end of 2010, the number of employees has increased 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. Expansion at home and abroad: businesses in Poland, the Czech Republic, Greece, South Africa and India are started. 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 enters new dimensions, too. In 2006, juwi builds solar plants with a total capacity of 12 megawatt, in 2009 one single park exceeds this number many times over: On a former military training area, juwi builds the third largest solar farm worldwide with 53 megawatt at the time. The company begins to enter new businesses: Several biogas and wood pellet plants are built and juwi has a focus on electromobility. Moreover, juwi starts with Repowering, which means that older turbines are replaced through fewer but more efficient ones.

2001 - 2005 A Second Business

Solar energy becomes juwi's second business. In 2005, several free-field plants with a capacity of approximately 3.5 megawatt are connected to the grid. Furthermore, there are a bunch of rooftop-plants, among them the plants on the Mainz theatre and the one on the rooftop of the stadium of German bundesligist Mainz 05. At the same time, juwi continues to be one of the leading specialists for wind energy onshore. In 2002, the company installs its 100th turbine. In the same year, the pilot project "energy landscape Morbach" in the Hunsrueck region is started with 14 turbines and solar plants. juwi also starts its business 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 in the US, Spain and Costa Rica follows

1996 - 2000 The Beginning

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 4 December 1996, they found the company Jung & Willenbacher Windenergie GmbH, later re-branded juwi GmbH. In 1997, the first plant in the Palatinate and three further plants in Rhinehessen are connected to the grid. Only two years later, juwi builds the largest wind farm in South Germany at the time with 19 turbines and a total capacity of 19.1 megawatt. In 1999, juwi enters the solar business and realises its first large PV-plant in the following year.
