Overview
Juwi is a German renewable-energy company that develops, builds, and operates power-generation facilities based primarily on wind and solar energy. The company was established in 1996 in Rhineland-Palatinate by Fred Jung and Matthias Willenbacher. Its name is derived from the initials of the two founders. Juwi began as a small founder-led business and later developed into an international project company serving the renewable-power market. The company’s activities cover the project lifecycle rather than the sale of a single consumer product. Juwi identifies and develops sites, works on project planning and permitting, arranges or supports financing, manages construction, and provides operational services for renewable-energy installations. Its portfolio includes solar parks and wind farms, while its broader offering also encompasses related infrastructure and energy-storage solutions where supported by project requirements. Juwi’s solar business includes the development and construction of utility-scale photovoltaic facilities. One of the projects associated with the company is the Waldpolenz Solar Park in Germany. Its wind business similarly focuses on the development and construction of wind farms intended to supply electricity to grids and other power users. These activities position Juwi as a business-to-business renewable-infrastructure provider rather than a retail electricity brand. The company is headquartered in Wörrstadt, in the German state of Rhineland-Palatinate. Reference material describes Juwi as having grown from a two-person operation into a company with more than 900 employees. Juwi is privately held and is a subsidiary of MVV Energie. The available reference material identifies Juwi as an active company, but does not provide a sufficiently current, independently sourced breakdown of its operating countries, installed capacity, annual revenue, or current management team. Those details should therefore be verified against current corporate disclosures before being added.
History
Juwi was founded in 1996 in Rhineland-Palatinate, Germany, by Fred Jung and Matthias Willenbacher. The founders’ initials provide the basis for the company name. In its early period, the business was operated by the two founders and concentrated on renewable-power facilities. As demand for renewable electricity increased, Juwi expanded its activities into the development and construction of wind and solar projects. Its business model centered on creating complete generation facilities rather than manufacturing a single standardized energy product. This required the company to combine site development, engineering, permitting, construction management, and operational support. Solar-park development became an important part of Juwi’s identity. The Waldpolenz Solar Park is cited as an example of a solar facility built by the company. Juwi also developed wind-farm projects, establishing a portfolio across the two principal forms of variable renewable generation identified in the available reference material. The company grew substantially from its original two-person structure. The available Wikipedia reference describes Juwi as having more than 900 employees, reflecting its evolution into a larger project-development and engineering organization. Its headquarters are in Wörrstadt, Rhineland-Palatinate. Juwi is now a subsidiary of MVV Energie and remains privately held. The available sources describe it as a company that builds renewable power-supply facilities, with activities spanning development, construction, and operation of wind and solar projects. They do not provide enough current detail to establish a complete chronology of ownership transactions, international subsidiaries, executive appointments, project capacity, or present geographic footprint. Such information should be supplemented with current company publications or filings.

Products and positioning
Integrated renewable-energy project developer and infrastructure partner serving utility-scale wind and solar generation.
Utility-scale solar power
Solar parks
Juwi develops and builds large photovoltaic power facilities intended to generate electricity for grid supply or other institutional energy users. Its role can span site development, planning, construction, and operational support. The Waldpolenz Solar Park is identified in reference material as an example of a solar park built by Juwi.
Wind power
Wind farms
Juwi’s wind business covers the development and construction of wind-power facilities. These projects require site identification, permitting, technical planning, construction coordination, and subsequent operational management. The available material identifies wind farms as a core part of Juwi’s renewable-generation portfolio but does not provide a complete project list.
Energy storage
Energy-storage systems
Energy storage is associated with Juwi’s broader renewable-energy solutions offering. Storage can be combined with renewable-generation projects to improve dispatchability and manage variable wind and solar output. The available reference material does not specify particular storage technologies, branded systems, or launch dates.
