Stadtwerke München

Stadtwerke München GmbH (Munich City Utilities) or SWM is a German communal company, owned by the city of Munich, which offers public services for the city and the region of Munich. The company supplies electricity for more than 95% of Munich's 750.000 households as well as natural gas, drinking water and, through its stake in the M-net Telekommunikations GmbH, telecommunications services. SWM is Europe's largest municipal utility company and ranks among Germany's principal energy providers according to company information. Expanding use of renewable energy has been a central element in the company's strategy since 2008.

Through its subsidiary, the Münchner Verkehrsgesellschaft mbH (MVG) (founded in 2001), the SWM also runs most of the inner city public transportation network by maintaining the Munich U-Bahn as well as the Munich Tramway and bus services.

Under the "M-Strom" name, SWM offers various electricity rates and related services for private and business customers in Munich and the surrounding region. Many offers are available nationwide. With more than 250,000 green energy customers, SWM refers to itself as one of the largest providers of green electricity in the private and commercial market in Germany. Within Munich city limits and the surrounding region, SWM operates twelve hydroelectric power plants, several plants which generate electricity from renewable energy, and the three cogeneration power plants Nord, Süd and Freimann, which generate around 70 percent of the electricity through cogeneration.
