Our History

1996

How it all began

Matthias Willenbacher and Fred Jung begin conducting wind measurements on their parents' farms in the Palatinate region. Shortly thereafter, the two founded the company Jung & Willenbacher Windenergie GmbH.

1997 to 1998

The first wind turbine

The first wind turbine is built on the Schneebergerhof in the Donnersberg district, and three more turbines in Spiesheim are connected to the grid shortly after.

1999 to 2000

The first solar system

JUWI enters the solar market and implements its first larger solar plant in Kirchheimbolanden the following year.

2001 to 2005

Global expansion of project development

In addition to the continuous expansion of its own wind and solar park projects in Germany, JUWI also becomes active abroad. In 2004, the company establishes its first wind farm in Brittany. This is followed by projects in the USA and Costa Rica.

2006 to 2007

Rapid growth

In 2006, JUWI constructs the world’s third-largest solar park at the former Lieberose military training ground. The international expansion continues as well.

2008 to 2010

New location, new growth

The company relocates to Wörrstadt and soon has to buid a second building. By the end of 2010, the number of employees rises to over 1.000. In 2009, JUWI builds the largest wind farm in Central America in Costa Rica. Additionally, projects are realized in Poland, the Czech Republic, Greece, South Africa, and India.

2011 to 2015

Focusing on core business

Political conditions in the home market of Germany and many other European countries deteriorate significantly. In Germany, the solar market collapses in 2012. At the end of 2014, MVV Energie from Mannheim acquires a stake in the JUWI Group. This partnership stabilizes JUWI sustainably and opens up new prospects.

2016 to 2021

Expansion of renewable energies

Globally, JUWI reaches new company records. Shortly after the turn of the year 2016/2017, JUWI surpasses the 2,000 megawatt threshold of wind energy capacity it has installed. In 2019, JUWI constructs its 1,000th wind turbine. MVV Energie AG from Mannheim acquires 100 percent of the shares in JUWI, providing another significant boost for the expansion of renewable energies.

2022

JUWI Merges with Windwärts

In 2022, MVV owned companies JUWI and Windwärts merge. This doubling of expertise and the new brand identity make JUWI an even more successful enabler of the energy transition. In April of the same year, JUWI completes the largest bifacial solar park in Europe in Greece. Additionally, in the same year, JUWI commissions the largest solar-hybrid project in the world on a mining site in Egypt.

2023 to the present

New employer brand and major projects

Globally, JUWI plans and constructs a variety of new large-scale projects in the wind and solar sectors. In early 2024, JUWI surpasses a total of 3.000 MW of installed wind energy capacity and 4.000 MW in solar energy. Additionally, as part of the new employer brand "The Power of Our Unity. Sustainable. Together. Strong" a new career website is launched.
