SWM Renewable Energies expansion campaign

By 2015, SWM plans to generate as much green energy in its own plants to supply all of Munich’s private households, subways and trams combined and by 2025 enough to supply the entire municipality. Munich will then become the first city with a population of more than a million to achieve this target! To realize this goal, SWM launched the Renewable Energies Expansion Campaign in 2008 and has allocated a budget of around nine billion euros for the project.

First target achieved

SWM has already achieved its first expansion target: By May 2015 its plants feed as much green energy into the grid as is consumed by all private house­holds and the electrically powered public transport system in Munich. An important step towards “100 percent green electricity for Munich”. And once its other ongoing projects have been realized and have come on stream, SWM will have a green energy generation capacity of over 3.5 billion kWh from its own plants. This is already equivalent to 50 percent of Munich’s power consumption.

In addition to water, geothermal, solar and biomass, wind power is playing an increasingly important role in SWM’s strategy. It is the most cost-efficient of the renewable energies.

Projects in Munich and the surrounding area take priority for SWM. For example, SWM is currently operating 22 photovoltaic plants and is involved in one photovoltaic plant here. The portfolio in Munich and the surrounding region also includes 13 hydroelectric plants, a biogas processing plant, two geothermal plants (one of which generates only heat) and a wind park. Other solar, wind, hydroelectric and geothermal plants are on the drawing board.

Nevertheless, SWM is unable to generate as much green energy here as the city requires, as the regional potential is limited. It is therefore participating in projects across Germany and Europe. Within Europe, SWM selects and makes use of the most suitable sites in terms of energy density and economic viability on which to build plants for generating green energy. This potential will safeguard Munich’s energy future.

SWM Green Energy in the European grid

The power will be fed into the grid where it is generated, so as to avoid trans­mission losses over long distances, among other reasons. The European grid can be compared to a huge lake. Everyone who generates electricity, feeds it into the “energy lake”; everyone who consumes energy, removes some. Every green kilowatt hour makes the European lake cleaner. Participation in climate-friendly energy plants outside Munich therefore makes good sense – after all, their environmental impact also benefits the citizens of Munich.

An in-depth look at some projects:

SWM operates over 100 onshore wind turbines in various parks in Germany. For example, with a 75 percent share, it is the majority owner of a large wind park project with 83 wind turbines in Havelland, Brandenburg. SWM’s share of 236 million kilowatt hours per year corresponds to the annual power consumption of around 95,000 Munich households.

In addition, SWM has onshore wind parks in North Rhine-Westphalia, Rhine­land-Palatinate, Saxony-Anhalt and, again, Brandenburg with 25 wind turbines. These generate approximately 100 million kWh of green energy per year, corresponding to the annual consumption of 40,000 Munich households.

SWM owns three wind parks in France. These generate a total of around 64 million kWh of green energy per year, corresponding to the consumption of nearly 26,000 Munich households.

In Sweden, SWM has an onshore wind park some 500 kilometers north of Stockholm, between the cities of Umeå and Sundsvall. It consists of 48 wind turbines with an output of 3 megawatts each. With the total wind park output of 144 MW, SWM will be able to generate a further 400 million kWh or so of green energy. This is equivalent to the annual consumption of around 160,000 Munich households. The wind park is fully operational since September 2015.

SWM is continuously enlarging its onshore wind-energy portfolio through its 33 percent share in wpd europe. To this end, the joint venture is currently active in 11 European countries with projects in various stages of development. Wind parks have already been realized in Poland, Croatia, Belgium, France and Finland for example. The joint venture employs 150 experts who plan, build and operate wind parks at home and abroad.

The DanTysk wind park is being built around 70 kilometers west of the island. It comprises 80 wind turbines with a combined output of 288 megawatts. The park officially came on stream in April 2015. SWM’s share in the project (49 percent) is equivalent to the annual consump­tion of around 250,000 Munich households.

A sister wind park, Sandbank, will be built 90 kilometers off Sylt. It will comprise 72 wind turbines with a combined output of 288 MW. SWM’s share in the project (49 percent) corresponds to the annual consumption of approximately 250,000 Munich households.

The Global Tech I offshore wind park was built 180 kilometers off the coast of Bremerhaven in the North Sea. It comprises 80 turbines with a combined output of 400 megawatts. The park officially came on stream in September 2015. SWM’s share (25 percent) corresponds to the annual consumption of around 140,000 Munich households.

RWE Innogy, SWM und Siemens built the Gwynt y Môr offshore wind park off the coast of North Wales with an output of 576 megawatts. In total, the park comprises 160 wind turbines. It is fully operational since June 2015 and generates an expected 1.95 billion kWh of energy per year. SWM has a 30 percent share in the joint venture. Its share of around 600 million kWh of clean energy per year is equivalent to the annual consumption of around 240,000 Munich households.

[Andasol_2011_Marcus Schlaf_008] Together with its partners, SWM built the Andasol 3 parabolic trough solar plant in Andalusia. Here, sunlight is focused with mirrors onto an absorber pipe containing synthetic oil. The focused sunlight heats the oil to around 400 degrees Celsius, generating a heat-transfer steam that powers turbine-driven generators to produce electricity. Andasol 3 has an output of 50 megawatts.

The plant began commercial operation in early 2012. SWM’s share in the power generation is equivalent to the annual consumption of around 30,000 Munich households.

The solar park in Rothenburg/Oberlausitz has a power output of 20.5 megawatts. SWM’s share (40 percent) corresponds to the energy consumption of 3,200 Munich households.

The thin-film solar plant in Lauingen on the Danube produces green energy with a rated output of 10 megawatts. SWM’s clean-energy share (49.9 percent) is enough to cover the annual requirement of around 2,000 households.

SWM has built a geothermal district heating plant in Sauerlach. It can produce electricity for 16,000 households and simultaneously provide heat for homes in Sauerlach.

Together with a partner, SWM has constructed a hydroelectric plant, the Prater plant, on the bed of the Isar River in Munich. It generates 10 million kWh of green energy per year, enough to supply 4,000 Munich households.

SWM is also pursuing other new hydroelectric projects in the region. It is currently planning to build a small ecological and fish-friendly moveable hydroelectric plant at the confluence of the Amper and Isar Rivers near Wang.

In addition, SWM is modernizing existing hydroelectric plants on the Isar River to generate more green energy and reduce even more carbon dioxide emissions.



  • All calculations are based on an average consumption of 2,500 kWh/year per Munich household.
  • The specified production figures are average and planned values, because solar, wind and water energy sources fluctuate.
