Windmühlenberg (Karlsruhe)

The Windmühlenberg , also known as the energy mountain, is a 60 m high former garbage dump ( Garbage dump West ) in Karlsruhe . The hill is located on the northern edge of the Karlsruhe Rhine harbor and belongs to the Knielingen district . It got its nickname “Energieberg” because two (2002 to 2018 three) wind turbines , a photovoltaic system and two block-type thermal power stations generate electricity and heat there. Since a landfill ban was introduced in 2005, no new waste has been stored there.

Energy generation

Between 1999 and 2003 three wind turbines were installed on the Windmühlenberg. The first two systems had an output of 750 kW each , the third 1,500 kW. In order to increase wind power production, the two smaller systems were replaced by a larger system of the Senvion type (2,000 kW). In 2005, Stadtwerke Karlsruhe also built a large photovoltaic system on the southern slope . Furthermore, the landfill gas that is produced by the decomposition of the waste has been burned in combined heat and power plants since 1997. However, since no more waste is deposited on the landfill, the development of landfill gas and thus also the generation of energy are steadily decreasing. A total of around 10 million kWh of electricity is generated from renewable sources on the energy mountain today . In addition, the operating and office buildings on the landfill as well as a nearby tram depot are supplied via a local heating network .

construction

In order to be able to build wind turbines on the landfill, detailed investigations had to be carried out and then special precautions had to be taken. On the one hand, landfills have only limited rigidity . In addition, the stored organic substances decompose, which means that the landfill gradually sinks. In order to be able to react to possible inclinations of the systems, correction options were therefore built in. Furthermore, a special foundation was developed with specialists from the Karlsruhe Institute of Technology .
