The company supplies electricity for more than 95% of Munich's 750.000 households[3] as well as natural gas, drinking water and, through its stake in the M-net Telekommunikations GmbH, telecommunications services.

[4] However, the company is also engaged in the industrialisation of the Norwegian wilderness through massive wind-turbines, which has created great opposition in Norway, among others in Sørmarka, Trøndelag.

Under the "M-Strom" name, SWM offers various electricity rates and related services for private and business customers in Munich and the surrounding region.

Cold ground water is used as the energy source for cooling within a closed loop system, and only the pumps are operated using electricity.

The high quality of the city's drinking water is, among other things, attributable to these procurement areas in the Bavarian Alpine foothills, as well as the sustainable forestry in these regions.

[11] The offer range also includes the energy saving advice project for low-income households, which SWM carries out together with Munich-based charities.

[4] By 2025, SWM is aiming to produce as much green electricity with its own plants as consumed by the whole of Munich – some 7.5 billion kilowatt hours per year.

[17] Münchner Verkehrsgesellschaft mbH (MVG), a subsidiary of SWM, offers a range of public transport in Munich, including subway, bus and tram.

Other managing directors are Ingo Wortmann (mobility), Helge-Uve Braun (technology), Karin Thelen (regional energy transition) and Gabriele Jahn (human resources, real estate, public pools).

To mark its fifth anniversary in 2013, the SWM Education Foundation introduced two new focuses to its work: its own scholarship program as well as an award.

The Foundation's award, which comes with 10,000 euros in prize money, has been presented every year since 2013 in recognition of special efforts in the field of education for disadvantaged children, teens and young adults.

[20] Socially disadvantaged and/or individually affected young people are supported by SWM via the "Stadtwerke Project" education initiative.
