The heating plant south , two in cogeneration powered combined-cycle plants of Stadtwerke München in Munich district Sendling near the middle ring. The south heating power plant is the most efficient generation location of SWM. Until 2018 it comprised two gas and steam turbine plants (CCGT). As fuel is natural gas used. In the plant, electricity is generated in the cogeneration process and the waste heat generated during electricity generation is used as district heating. Stadtwerke München is currently expanding the energy location south and building a geothermal system there.
history
Electricity has been generated at this location since 1899. In the 1950s, the system was supplemented by the first facilities for generating district heating , which were expanded in 1969 after a new heating plant with three boilers for high district heating requirements went into operation in winter in 1968. In 1970, a waste incineration plant was built in the power station for the Munich Waste Management Office , but it was shut down again in 1997 due to falling waste volumes. In 1980 a gas and steam turbine plant (GuD 1) with two gas turbines and one steam turbine was put into operation. The high-pressure steam boilers from 1968 were replaced by a modern CCGT 2 in 2004. Like the CCGT 1, it consists of two gas turbines and one steam turbine. Both plants are operated in combined heat and power. Gas is used as fuel in all three systems. The thermal energy of the exhaust gases from the gas turbine, which can reach temperatures of up to 540 degrees Celsius, is not released into the environment without being used, but is transferred to the steam turbine via a heat exchanger, where again energy, this time for heating and hot water, is generated in the CHP process.
The highest chimney with a height of 176 m (it belonged to the old high-pressure system from 1970 with 2 steam turbines) is now without function and should actually be demolished in 2019. In its place, a new chimney about half as high is planned, as well as a heat storage facility north of the power plant building, at the site of the former oil tanks. In addition, the power plant will also function as a refrigeration center in the future. A district cooling network up to the main train station is to connect all smaller cooling centers and in the future also supply the wholesale market and the slaughterhouse with cold.
CCGT 1
| Gas turbine | Steam turbine | |
|---|---|---|
| Thermal performance | 425 MW | |
| Electrical power | 99 MW | 82 MW |
The maximum possible thermal extraction into the district heating network is 255 MW.
CCGT 2
| Gas turbine | Steam turbine | |
|---|---|---|
| Thermal performance | 502 MW | |
| Electrical power | 139 MW | 139 MW |
The maximum possible thermal extraction into the district heating network is 463 MW.
power
The thermal power station generates a maximum district heating output of 814 megawatts . The hot water networks Sendling, Neuperlach and downtown are available as customers . The electrical output amounts to a maximum of 698 megawatts and is fed into the urban 110 kV high-voltage network of the distribution network operator SWM Infrastruktur .
Greenhouse gas emissions
The southern thermal power station emitted the following amounts of carbon dioxide:
| year | Carbon dioxide (tons) |
|---|---|
| 2010 | 1,360,000 |
| 2011 | 1,090,000 |
| 2012 | 929,000 |
| 2013 | 751,000 |
| 2014 | 620,000 |
| 2015 | 591,000 |
| 2016 | 813,000 |
| 2017 | 1,002,400 |
District heating from geothermal energy
A new geothermal system for Stadtwerke München is being built at the southern heating power station. The system will make a significant contribution to providing 100% of Munich's district heating with renewable sources by 2040. The system will supply 80,000 Munich residents with environmentally friendly district heating. In order to achieve this goal, SWM needs several geothermal systems , three of which are still in operation ( Messe Riem , Sauerlach and Freiham ). In 2016, seismic measurements were carried out in the greater Munich area over several weeks in order to find new locations for future drilling. The location of the thermal power station turned out to be particularly economically sensible. There you will find good thermal conditions as well as sufficient space (demolition of the old oil tanks) and good integration into the already existing district heating networks. Six wells with a depth of up to 4,300 m are planned. Since a large part of the inner city district heating network is not a hot water network but a steam network, it will have to be converted in several construction phases over the next few decades. Renewable energy sources are not suitable for steam production in the climatic conditions that prevail there. Most of the steam network is currently supplied by the northern heating plant .
particularities
With a total height of 176 meters, the large chimney of the power plant is the second tallest structure in Munich after the Olympic Tower . It is expected to be dismantled in the course of 2020.
