100% green electricity for Munich by 2025
On completion of the already initiated or executed projects, SWM will have a generation capacity of over 3.5 billion kWh of green electricity from its own plants. That equates to 47% of Munich’s power consumption and is significantly more than the requirements of all of Munich’s approximately 800,000 households as well as the underground and tram systems. Further projects with great poten-tial (particularly in the field of wind power) are already in planning.
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.
Up to 2025, we are earmarking a budget of 9 billion euros for the expansion of environmentally-friendly energy generation. Priority is clearly given to SWM projects in Munich and its region. However, SWM is unable to generate enough renewable energy to meet the needs of the city of over a million inhabitants here alone. This is why the company also has activities in other parts of Germany and Europe. It selects and uses the locations best suited to the construction of regenerative energy plants in Europe from a power generation and economic perspective. SWM is harnessing this potential to meet Munich’s future energy requirements.
Projects of the expansion campaign
An in-depth look at some projects:
SWM is continuing its proven partnership with Vattenfall with the construction of the Sandbank offshore wind park in the German North Sea. 72 Siemens wind power turbines in the 4-megawatt (MW) class with a total capacity of 288 megawatt are being installed 90 km off Sylt. Construction work is scheduled to begin in 2015.
Vattenfall has a 51 percent holding in Sandbank Offshore GmbH, the company set up for the implementation of the project, while SWM holds a 49 percent stake. After the DanTysk offshore wind park, Sandbank is the second largest infrastructure project jointly undertaken by Vattenfall and SWM as part of the change in energy policy. With its participation in Sandbank, SWM will increase its green electricity production volume to over 3.5 billion kilowatt hours. This equates to just under 47 percent of Munich power consumption which stands at 7.5 billion kWh per year.
Through our 33% stake in wpd Europe, we are expanding our existing onshore wind power generation portfolio in Germany. The joint venture is already operating in 11 European countries with projects at various stages of development.
Over the coming years, the objective is to complete already initiated wind park projects and to plan, construct and operate a large number of additional wind parks with total output of several thousand megawatts. Around 140 experts at the joint venture are working towards the attainment of development and expansion objectives in Germany and abroad.
In France SWM has purchased three wind parks from the tur-bine manufacturer Nordex. Al-together they generate 64 mil-lion kWh of green electricity a year. This covers the require-ments of almost 26,000 households in Munich and cor-responds to savings of 56,500 tonnes of CO2 annually.
SWM has commissioned Nordisk Vindkraft to construct an onshore wind park in Sweden. It will build the facility for SWM around 500 kilometres north of Stock-holm between the towns of Umeå and Sundsvall.
The park consists of 48 wind power turbines, each with an output of 3 MW. The park’s total output of 144 MW will enable SWM to generate an additional 400 million kWh of green electricity a year. This volume of power equates to the annual consumption of around 160,000 Munich households. The project is due for completion by spring 2015. Reduction in carbon dioxide emissions: 350,000 tonnes a year.
Together with partners, SWM has acquired nine wind parks in Havelland (Brandenburg) with 83 plants from wpd in Bremen. SWM is the majority shareholder with a 75% stake. Its share of 236 million kWh per year meets the annual requirements of around 95,000 Munich households. All of the wind parks combined prevent the emission of 280,000 tonnes of CO2 per year.
In summer 2009, SWM acquired five wind parks in Germany (Brandenburg, North Rhine-Westphalia, Rhineland-Palatinate, Saxony-Anhalt) from wpd. The 25 wind power plants generate around 100 million kWh of green electricity per year. This meets the annual requirements of 40,000 Munich households and prevents the emission of 90,000 tonnes of CO2 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. We have set up our own company for this purpose – SWM Bayernwind. In collaboration with the Bavarian municipalities, SWM aims to generate around a billion kilowatt hours in wind power a year by 2020. SWM will thus become the driving force behind the change in energy policy in Bavaria.
In collaboration with Vattenfall, SWM is constructing the DanTysk wind park in the North Sea around 70 kilometers west of the island of Sylt. The park will comprise of 80 wind turbines with total output of 288 megawatts and will supply around 500,000 households with clean electricity from the North Sea wind.
Construction work at the site has already begun, and the park is set to enter full service in the beginning of 2015. SWM’s stake in the project (49%) will meet the annual requirements of around 250,000 Munich households. The plant will prevent the emission of a total of 1.1 million tonnes of CO2 per year.
RWE Innogy, SWM and Siemens are constructing the Gwynt y Môr offshore wind park off the coast of North Wales with an output of 576 megawatts.
The park will comprise 160 wind power plants in total. Completion is scheduled for 2014 from when it will generate around 1.95 billion kWh of electricity per year. SWM has a 30% stake in this joint venture. Its share of around 600 million kWh in green electricity per year equates to the annual consumption of around 240,000 Munich households. The plant will prevent the emission of a total of 1.7 million tonnes of CO2 per year.
The construction of one of the largest offshore wind parks in the North Sea, Global Tech I, has been finished. The wind park’s 80 turbines are able to produce 1.4 billion kWh of green energy per year. The SWM stake (25%) will meet the annual consumption of 140,000 Munich households. The plant will prevent the emission of a total of 1.2 million tonnes of CO2 per year.
SWM and its partners have constructed the large-scale solar power plant Andasol 3 in Andalusia. It has an output of 50 megawatts. In the beginning of 2012 commercial operations started.
It has an output of 50 megawatts and went into commercial operation at the beginning of 2012. SWM’s share of electricity generation will meet the annual requirements of 33,000 Munich households. In total, the plant will prevent the emission of 150,000 tonnes of CO2 per year.
In Sauerlach, a community in the South of Munich, SWM have built a geothermal power plant. The site can generate electricity for 16,000 households and can also provide heating for households in Sauerlach. It will prevent the emission of 35,000 tonnes of CO2 per year.
Together with a partner, SWM has installed a hydropower plant - the Praterkraftwerk - on the bed of Munich’s Isar river. It generates 10 million kWh of green electricity a year, enough for 4,000 Munich households. In total, the plant prevents the emission of 9,000 tonnes of CO2 a year.
We are also modernizing the Isarwerke 1 and 2 and Maxwerk plants which will generate around 6.3 million kWh of green electricity more per year after completion, enough to supply an additional 2,500 Munich households with green electricity. In total, it will prevent the emission of around 5,600 tonnes of CO2 a year.
- All calculations are based on consumption of 2,500 kWh/year for a Munich household.
- The CO2 reductions are calculated on the basis of a specific CO2 value of 0.883 t CO2/MWh. A conventional hard coal-fired power plant with 38.5% efficiency is used as comparison; the specific CO2 value of hard coal is set at 0.34 t CO2/MWh. The CO2 reduction potential of the entire plant is indicated.
