The Stuttgart-Gaisburg thermal power station is a natural gas- fired power station on the banks of the Neckar in Stuttgart - Gaisburg , which is operated by EnBW Energie Baden-Württemberg .
Power plants 1 and 2 (old power plant), shut down
The power plant consists of two power plant parts. Power plant 1 with the former units 11 and 12 has been shut down. Power plant 2 is a steam busbar heating power plant with three steam generators. One boiler is fired with coal , the other two with gas or optionally with light heating oil. The two striking chimneys are 160 and 125 m high. A former 80 meter high collecting chimney was replaced in 1979 by the 125 meter high chimney. Another existing chimney is 65 m high.
The system is used to generate district heating . As a special feature, the power plant is the only EnBW power plant to have a fluidized bed boiler . In the 1980s, the old boilers of KW 1 ( Benson boiler ) from the 1950s and 1960s were replaced by modern systems and provided with primary desulphurisation and denitrification devices. The system has a maximum heat output (heat extraction in the district heating network) of 273 MW.
The former gas turbine that was used for start-up was dismantled in early 2014. The last time coal was delivered to the power plant was on March 17, 2018.
The power plant was finally shut down at the end of 2018.
Block 3 (discarded)
At the same time, plans were made to build another coal block (Gaisburg III) at the site, which was also intended for electricity generation. However, these plans were dropped at the end of 1988, at the same time as Unit 2 in the Neckarwestheim nuclear power plant was put into operation .
Natural gas cogeneration plant (since 2018)
In May 2015, plans became known according to which EnBW would like to build a new natural gas heating power plant on the property of the existing power plant. After commissioning, the old power plant was to be shut down and demolished. The new cogeneration plant was to consist of three natural gas-fired combined heat and power plants with a total of 30 MW electrical and 30 MW thermal output, a heat storage unit with a capacity of 300 MWh and natural gas / oil-fired boilers with 210 MW thermal output. The construction costs were estimated at around 75 million euros. On December 16, 2016, the Stuttgarter Nachrichten reported that EnBW would start building the new power plant in January 2017. From spring 2017 the new power plant was built right next to the existing old power plant. When the new power plant went into operation, the old power plant was taken off the grid. The power plant was in trial operation from December 2018 to April 2019; completion and final commissioning took place in April 2019.
Network connections
electricity
The grid connection takes place at the 110 kV high voltage level in the power grid of the distribution network operator Netze BW . All outgoing lines are now underground cables.
District heating
The Gaisburg combined heat and power plant is connected to the Altbach / Deizisau combined heat and power plant in the southeast and the Stuttgart-Münster waste incineration plant to the north via a district heating pipeline . This district heating pipeline is also known as the “Middle Neckar Rail” and is 14 km long. The middle Neckarschiene runs partially above ground along the Neckar and the B 10 . It feeds into the individual district heating distribution networks of the districts supplied, which are used for the local distribution of heat through to the individual house connections.
