Bruchmühlbach, Germany

  • Target: 100% renewable energy
  • Status: Achieved
  • RES: Wind farms, biogas cogeneration plants, a solar PV plant, and rooftop solar systems.
  • Implementation: The municipality of Bruchmühlbach-Miesau consists of several small towns and villages, located in the state of Rhineland-Palatinate in the west of Germany. The town of Miesau in particular is well-known for the “Miesau Army Depot” (the largest American ammunition depot outside the US). The town is also just a few miles from the famous Rammstein Airbase and Landstuhl Medical Centre. Today, Bruchsmühlbach-Miesau is also known for its 100% renewable energy supply systems. In order to achieve this 100% goal, the mayor initially approached the US Army authorities with the plan of placing a 1-MW solar PV plant on the roof of storage buildings within the military base. The project was finally approved in 2012 by the local American military authorities and the national German authorities, and following this success, the municipality began planning for a biogas cogeneration plant to be built, also with the US base's cooperation.

    The plants proposed were to help boost the municipality's existing energy infrastructure. By then, it already operated a wind farm consisting of 10 turbines that generated about 37 GWh/a, a biogas plant that generated 2.7 GWh/a, and over 200 rooftop solar systems generating 2 GWh/a.  When a 5 turbine wind farm was completed in 2013, it produced an additional 47 GWh/a. At this point the community of Bruchsmühlbach-Miesau was able to produce 290% of its electricity demand. The wind farms especially enjoyed good support in the area due to strong local participation and the emphasis on regional value creation.
