Großkrotzenburg Power Station

F2

The Staudinger power plant is a predominantly fueled with coal-fired thermal power plant at Großkrotzenburg in Hesse, near Hanau, located right on Main. It is named after the first chairman of the Preussen Elektra, Hans Staudinger and operated by E.ON power plants GmbH. Prior to commissioning of the Biblis nuclear power plant was and since its closure in March 2011, it is again the largest power station of Hesse, and with about 430 employees, the largest employer in Großkrotzenburg. The power plant has to delivery of coal an electrified rail connection to the Main-Spessart -Bahn ( trains ), the main component is but delivered by ship across the Main.

Since January 2013, only block 5 is with an electrical output of 510 megawatts in control mode. Block 4 can deliver up to 2016 on the instructions of the Federal Network Agency in emergency peak-load electricity. Blocks 2 and 3 were at 31 December 2012, Block 1 finally shut down on 30 April 2013.

In 2010, the Staudinger power plant was loud European PRTR pollutant register with about 4.5 million tonnes of CO2, the coal power plant with the fourth highest carbon dioxide emissions in Germany.

Equipment

The power plant has a total of five blocks, which are still all made, but of which only one is operated regularly. A planned sixth block was canceled in 2012 for economic reasons.

Blocks 1, 2 and 3

The identical and the 249 -MW Unit 1 and Unit 2 in 1965, the 293 MW net power providing unit 3 in 1970, decommissioned in each case as a medium load power plants put into operation and 31 December 2012. Unit 1 was kept ready to protect the district heating supply beyond that date until 30 April 2013.

All three blocks were used for the production of medium-load current, block 1 and block 2 also the extraction of district heating. Block 2 was transferred in April 2001 in the cold reserve and not be approached until the formal decommissioning.

In 2006, E.ON announced Staudinger 1 and 3 and the de facto shut down permanently at 31 December 2012 since 2001 has operated Block 2 - at this time the company went from a recording operation of Staudinger 6 during the year of 2012. Because as of 2010 with a start-up of the block 6 was not expected before 2016, E.ON decided in autumn 2010 to revoke the waiver at least for block 1. This suggestion E.ON 's gave the Darmstadt Regional Council held in May 2011. 31 August 2011 recommended the Federal Network Agency, due to the test a further operation of Staudinger 3 until at least March 31, 2013 in the wake of the closure of older nuclear power plants expected power shortages in winter 2012/2013.

In December 2012, the Darmstadt Regional Council announced against an earlier decision that Unit 1 as well as the blocks had to be 2 and 3 as provided closed at the end of 2012. The basis for this decision which rejected E.ON 's complaint regarding the continued operation of the power plant dates, where E.ON as well as first seek closure of Altblöcke at the Staudinger power plant and later withdrawn. This court decision is binding also for the Staudinger power plant; the operating license to go out so that by 1 January 2013, as given by E.ON aside declaration, despite subsequent revocation can not be undone. Thus, the extension later applied for the operating life of Unit 1 was not possible. Because there was no other reserves available to hedge the district heating supply Hanau and Great Krotzenburgs during the heating season 2012/2013, the continued operation of the block 1 was tolerated until 30 April 2013.

Units 1 and 2, which were operated with once-through cooling, feature two 38 -meter high cooling towers fan that can be switched on in the summer heat or low level of the Main, to reduce the water pollution of the river. Block 3, which features a 50 -meter high cooling tower fan, could also be run in cycle cooling mode both in the run - as. The chimneys of Block 1, 2 and 3 are each 195 meters high.

Block 4

Staudinger 4 is fired with natural gas and is used to generate peak load power. Production started at the 622 MW net rated power delivered and thus strongest block the site in 1977. The cooling tower of Unit 4 is 128 meters, its chimney 250 feet high, and thus the tallest chimney in Hesse. In 2009 the interior of the cooling tower of Unit 4 was restored, in 2011 was followed by the restoration of the exterior walls. As part of the exterior renovation of the cooling tower received a new coat of paint in light gray with a sky blue ring in the upper half.

In May 2012, the Financial Times Germany reported that E.ON plan Staudinger 4 and three other gas-fired power plants in Bavaria shut down due to lack of profitability in 2013. On the part E.ON 's were such notifications initially denied. The end of 2012, E.ON finally announced its intention to shut down the block, and told him on December 1, 2012 from participation in the electricity market from, but it is due to an agreement with the Federal Network Agency, which had declared the block for systemic importance to the end of the first quarter 2016 of E.ON held in readiness. Then, a sequence control found or the block must be shut down, E.ON should the block not now take back.

Block 5

The 510 -megawatt block 5 was commissioned in 1992. It is used to generate base-load electricity, district heating also is coupled. A special feature of block 5 is that it has no chimney, but the cleaned flue gases are emitted through the 141 -meter high cooling tower. He is fueled by coal and co-combustion of municipal sewage sludge and municipal similar (three percent). 60,000 tons, equivalent to 10 % of all costs incurred in Hesse sewage sludge incinerated each year. In block 5 up to 19 tons of petroleum coke are disposed of by incineration hourly.

Formerly planned extension to block 6

As part of the modernization of its power plants, the energy company E.ON decided in December 2006, Staudinger to expand a power plant unit ( with similar design like dates 4). Originally Stadtwerke Hannover were involved with a share of 12.6 %, but withdrew in late 2010 of this investment back. On 29 December 2010 the Darmstadt Regional Council granted the partial license for Block 6 In November 2012, E.ON announced that the project would not be realized. The reason for this economic considerations were called, because the energy- economic situation does not provide sufficient security of investment.

Technical data for Session 6:

• Use in base load

• District heating: 300 MW
• Efficiency: 46%
• Cooling tower height: 180 m
• Boiler house height: 122 m
• Fuel: coal
• Fuel consumption: 385 tons of coal per hour = three million tons / a
• CO2 emissions 5.2 million tons / a
• Particulate matter emissions: 221 tonnes / a
• Sulfur oxide emissions: 1219 tons / a

• Start of construction: planned Fall 2008
• Commissioning: was open, originally planned in 2012

The application position was provided by E.ON in late 2007.

Against the expansion plans of E.ON, numerous communities, cities and citizens' initiatives in the region have made, because the additional burden on the Rhine -Main region was unacceptable. The Immissionsradius of ten kilometers arises from the low cooling tower height. This radius, which ranges from Main valley to Alzenau and Erlensee to Rodgau- Dudenhofen, limits the area where most pollutants are immittieren. By the Hessian state government, a regional planning process was initiated to include the concerns of the region into consideration the location. Following E.ON can then submit an application after Confederation Pollution Control Act ( Federal Pollution Control Act ) filters ( as of May 2008).

To counteract the existing concerns of the population and to inform about the construction project are E.ON power plants GmbH since the beginning of 2007, the free newspaper out neben.an. Here the Staudinger power plant will continue to be presented in its current form and report, for example, report on open days, or the art of district heating explained to understand. It should be answered especially the questions of the residents of the power plant.

On 29 December 2010 the Darmstadt Regional Council granted the partial license for block 6

Planned coal round bearings

Furthermore, began in January 2008, the preparatory construction work for two closed coal round bearing that reach a capacity of about 220,000 tons of coal each with a height of 58 meters and a diameter of 125 meters. According to E.ON, there is no comparable structure in Germany.

In November 2007, the Darmstadt Regional Council had granted planning permission. In April 2008, work began on the construction of the first coal camp, he has now been completed (as of 2010 ). The construction of the second bearing the company sets but from the course of the regional planning process for block 6 dependent.

Mains connection

The power connection for block 1 is done on the 220 ​​kV and for units 3 to 5 on the 380 kV high- voltage level in the power grid of the transmission system operator TenneT TSO.
