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 house-holds and the electrically powered public transport system in Munich. An im-portant 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.
Wind, hydro, solar, biomass and geothermal energy
From the outset, SWM has focused exclusively on cost-efficient projects that are self-sustaining. 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 clearly take priority for SWM. For example, SWM is currently operating 21 solar plants (including one solar thermal plant) and is involved in one other plant in Munich and its region. The portfolio in Munich and the surrounding region also includes 13 hydroelectric plants, a biogas plant, a biogas processing plant, two geothermal plants (one of which generates only heat) and a wind park. Other solar, wind and hydroelectric 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.
Projects of the expansion campaign
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 kWh per year corresponds to the annual power consumption of around 95,000 Munich households. As a whole, the wind park saves 280,000 tons of carbon dioxide per year.
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. Carbon dioxide saving: 90,000 tons per year.
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 and saving around 56,500 tons of CO2 per year.
In Sweden, SWM has commissioned the construction of an onshore wind park by Nordisk Vindkraft. The wind park will be built for SWM some 500 kilometers north of Stockholm, between the cities of Umeå and Sundsvall. It will consist of 48 wind turbines with an output of 3 mW 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 scheduled to be completed in early summer 2015 and will save 350,000 tons of carbon dioxide yearly.
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 and Belgium, 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 in collaboration with Vattenfall around 70 kilometers west of the island. It comprises 80 wind turbines with a combined output of 288 megawatts. The park 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. CO2 saving of the plant as a whole: 1.1 million tons per year.
SWM is continuing its proven partnership with Vattenfall with the construction of the Sandbank offshore wind park in the German North Sea. Sandbank, will be constructed 90 kilometers off Sylt. It will comprise 72 wind turbines with a combined output of 288 MW. Construction is scheduled to start in 2015. SWM’s share in the project (49 percent) corresponds to the annual consumption of approximately 250,000 Munich households. CO2 saving of the plant as a whole: 1.1 million tons per year.
The Global Tech I offshore wind park will be built 180 kilometers off the coast of Bremerhaven in the North Sea. It will comprise 80 turbines with a combined output of 400 megawatts. The park will come on stream in late summer 2015. SWM’s share (25 percent) corresponds to the annual consumption of around 140,000 Munich households. Carbon dioxide saving of the plant as a whole: 1.2 million tons per year.
RWE Innogy, SWM und Siemens are building the Gwynt y Môr offshore wind park off the coast of North Wales with an output of 576 megawatts. In total, the park will comprise 160 wind turbines. Once it is fully operational in June 2015, it will generate 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. Carbon dioxide saving of the plant as a whole: 1.7 million tons per year.
Bavaria has the greatest unharnessed wind power potential in the whole of Germany. SWM aims to tap into this in cooperation with Bavarian municipalities. SWM will thus become the driving force behind the change in energy policy in Bavaria.
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. Carbon dioxide saving of the plant as a whole: 150,000 tons per year.
The solar park in Rothenburg, Oberlausitz has a power output of 20.5 MWp. SWM’s share (40 percent) corresponds to the energy consumption of 3,200 Munich households. The plant as a whole saves around 18,000 tons of carbon dioxide per year.
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. CO2 saving of the plant as a whole: 8,800 tons per year.
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. CO2 saving: 35,000 tons per year.
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. CO2 saving of the plant as a whole: 9,000 tons per year.
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.
Explanations: - All calculations are based on an average consumption of 2,500 kWh/year per Munich household.
- CO2 savings are calculated on the basis of a specific CO2 value of 0.883 tons CO2/MWhel. A conventional anthracite-fired power plant with an efficiency of 38.5 percent serves for comparison; the specific CO2 value of anthracite is assumed to be 0.34 tons CO2/MWh. In each case, the CO2 saving potential of the plant as a whole is stated.
- The specified production figures are average and planned values, because solar, wind and water energy sources fluctuate.
