The cogeneration plant Lausward is a gas and steam turbine power plant ( CCPP ) and, since 1957, the largest power plant in the North Rhine-Westphalian capital Dusseldorf . It is located at the Düsseldorf harbor and is visible from afar with its green illuminated "city window", the glass-enclosed chimney of the Fortuna block. The power plant also generates traction current . A traction current line crosses the Rhine in the immediate vicinity of the Lausward power station.
history

The power plant was originally a hard coal power plant . Plans that the Stadtwerke management presented in 1938 for a new power plant on Lausward were dashed again and were only taken up again in the 1950s. The agreement with the Deutsche Bundesbahn to produce traction current was essential in the approval process . In 1955, construction began on the first Anton block , which went online for the first time in 1957. By 1977 the power plant was gradually expanded to include the Berta , Cäsar and Dora units and the first Emil natural gas unit . Up until 1999, the three 100 and two 150 meter high chimneys of the Lausward, required for coal firing, shaped the image of the Düsseldorf harbor, which are now being gradually dismantled. The power plant has been gradually converted since 1998. The Berta and Caesar blocks were closed; the block Anton by a gas-powered replaced gas and steam turbine power plant (CCGT), which now power and district heating produced. In 2016, the Fortuna block, another combined cycle power plant block with additional waste heat utilization, went into operation. Since 2017, a large district heating storage system has also increased the flexibility of the system. The power plant is operated by Stadtwerke Düsseldorf AG together with EnBW .
Current power plant units
Block Anton
Block Anton is a combined cycle power plant and has an electrical output of 103 MW. In addition, up to 75 MW of district heating can be extracted. The electrical efficiency in condensation mode is around 54%; if district heating is also extracted, the fuel efficiency increases to around 87%.
Block Emil
Block Emil is also a combined cycle plant with optional district heating extraction. The maximum electrical output is 420 MW, and it is also possible to generate 140 MW district heating. The fuel efficiency in combined operation is up to 68%.
Reserve boiler
Three reserve boilers are used to secure the district heating supply if district heating is required but no electricity. Similar to the way large instantaneous water heaters work, the three systems generate up to 180 MW of district heating with flame tube boilers . Natural gas is used as fuel.
According to the biologist Fabio Rochol, the heat of the waste water from the power plant blocks favored the spread of the catfish in the Rhine , so that particularly large specimens of this predatory fish occur in abundance near the Lausward power plant.
Fortuna block
history
According to the plans of the municipal utility, the disused units were originally to be replaced by a 400-megawatt hard coal-fired power station. In order to prevent construction and to promote environmentally friendly energy generation, environmental associations and initiatives as well as individuals have come together to form the Clean Electricity Action Alliance on the Rhine - ASTR (H) EIN . On April 23, 2010 the supervisory board of Stadtwerke Düsseldorf decided not to pursue the planning of the coal-fired power plant any further. Instead, he decided in December 2011 to build a new gas -fired combined cycle power plant . This was put into operation in January 2016 after around 2.5 years of construction. The facade was designed by the Aachen architectural office kadawittfeldarchitektur . To protect birds, the glass facade elements were almost completely printed with 3 mm wide strips with a distance of 47 mm from the edge. This bird-friendly design reduces the bird strike on glass as much as possible.
technology
The combined cycle power plant has an electrical output of 595 MW (during test drives before the official commissioning, a maximum electrical output of 603.8 MW was achieved) and was built by Siemens , the investment total is around 500 million euros. 300 MW can be extracted from district heating. The block was designed in a single-shaft arrangement, the gas turbine and the steam turbine work in combination on one shaft and also drive only one generator , which minimizes generator losses. The main component of the power plant is a type SGT5-8000H gas turbine also supplied by Siemens . It serves as a heat source for a waste heat boiler , which in turn acts as a steam generator for the steam turbine. In the event of a so-called blackfall (nationwide or even Europe-wide power failure), the GuD F is able to independently supply Düsseldorf with energy. After initial help from the gas turbine power plant in Flingern, the “Fortuna” block can supply the city of Düsseldorf again and help restore or stabilize the supra-regional power supply. A hot start can go from zero to full load in 40 minutes, a normal start in 116 minutes.
A 34 m high and 29 m diameter hot water district heating storage tank went into operation in spring 2017. The storage facility has a volume of approx. 35,700 m³ and a storage capacity of approx. 1,340 MWh. It represents an investment of 10 million euros. As soon as more heat is extracted than required to generate electricity, the storage unit absorbs this excess heat energy. Conversely, if there is a low demand for electricity, but at the same time high heat demand, this is covered by the storage tank. This enables electricity and district heating generation to be decoupled from the city's heat requirements.
Efficiency and emissions
The electrical efficiency in condensation operation is more than 61% (during test drives before the official commissioning, a maximum net efficiency of 61.5% was achieved), which even surpasses the current record holder, the Irsching power plant . With a maximum heat extraction of approx. 30%, more than 85% fuel efficiency is achieved and carbon dioxide emissions of approx. 230 g / kWh.
Traction current
Two 25 MW converters owned by the railway are currently in operation.
