The Neurath power plant is located in the south of Grevenbroich and borders the area of ​​the municipality of Rommerskirchen and the city of Bedburg . The operator is RWE in Grevenbroich- Neurath ( Rhein-Kreis Neuss ). Based on the installed gross electrical output of 4,400 megawatts, it is the largest power plant in Germany and the second largest lignite power plant in Europe after the Bełchatów power plant in Poland.

The power plant is used to generate base load electricity and has a net electrical output of over 4,211 megawatts . The coal is obtained from the opencast mines of the Rhenish lignite area , in particular the Garzweiler opencast mine , via the rail connection to the north-south railway . With CO 2 emissions of 32.1 million tons, the power plant caused the second highest greenhouse gas emissions of all European power plants in 2015 .

The track system of the north-south railway , which is used to supply the Neurath power plant, was blocked by activists for more than 40 hours in June 2019 to draw attention to the large CO 2 emissions of the power plant.

Power plant units

The power plant consists of seven blocks (3 × 300 MW, 2 × 600 MW and 2 × 1100 MW nominal), which were built between 1972 and 1976 and 2012, and has a gross output of approx. 4400 MW.

Blocks A through E.

Existing power plant (without BoA new building); Blocks A (right) to E (left)

In the 1980s, a flue gas cleaning system was retrofitted for blocks A to E. Since then, the exhaust gases have been discharged via the cooling towers.

The system also has two so-called bypass chimneys, one of which is assigned to blocks A – C and the other to blocks D to E. The former is 194 meters high, the latter 196 meters high. The bypass chimneys enable the system to be operated in the event of a defective flue gas cleaning system, but this rarely occurs and which is why most power plants do without bypass chimneys (source: RWE press office).

All blocks feed into the transmission network of the network operator Amprion : Block A is via the Osterath substation on the 220 kV level, blocks B to D via the Opladen switchgear on the 380 kV level and block E via the switchgear Rommerskirchen , also on the 380 kV level, is connected to the extra high voltage network.

According to an agreement between the Federal Ministry for Economic Affairs and Energy and the lignite-fired power plant operators RWE, Vattenfall and Mibrag, Block C is to be transferred to reserve on October 1, 2019 and finally shut down four years later.

Blocks F and G ("BoA 2 and 3")

history

Construction site in August 2008
KW Neurath, Blocks F and G (BoA 2/3) from the south
KW Neurath, BoA 2/3 from the north

In September 2005, RWE decided to build two new units ( F and G ) of the type "Lignite Power Plant with Optimized Plant Technology (BoA)" at the power plant. As a further development of the BoA block in the Niederaussem power plant (BoA 1), the new blocks also bear the designation "BoA 2 and 3" . Construction work began in January 2006. The BoA blocks should each have an output of 1100 MW with an efficiency of 43 percent. In 2008, RWE stated that the construction, which is one of the largest construction sites in Europe, would involve an investment of 2.2 billion euros. In December 2011, RWE admitted that the project had become "significantly more expensive" at EUR 2.6 billion. The BoA 2 and BoA 3 boiler houses are the tallest boiler houses in the world with a height of 173 meters. The cooling towers are 172 meters high.

The commissioning originally planned for the end of 2009 was delayed due to the accident mentioned below, in which a considerable part of the new building was destroyed. On November 29, 2011, both units reached full load together for the first time and had produced more than 1.5 billion kilowatt hours of electricity during the commissioning phase. Both blocks had been in test operation since May and October 2011, respectively, the final commissioning with the reporting of the blocks to the EEX electricity exchange took place on July 8, 2012 (Block G) and on August 3 (Block F). Since then, both units have also been feeding into Amprion's transmission network at the 380 kV level and are connected via the Rommerskirchen switchgear .

On August 15, 2012, the official celebration of the commissioning of the new units took place in the presence of North Rhine-Westphalia's Prime Minister Hannelore Kraft , Federal Environment Minister Peter Altmaier and other guests. It was wrongly described in several media as the world's largest lignite power plant, in fact it is only the second largest in Europe (after the Bełchatów power plant in Poland). It is true, however, that the two new BoA units F and G, each with 1,100 MW gross, were the most powerful lignite power plant units in the world at the time. The construction costs were given as 2.6 billion euros.

At the end of 2011 and in spring 2012, RWE took six of the twelve old 150 MW units in the Frimmersdorf power plant off the grid.

Problems

On August 30, 2012, in the early afternoon, both BoA blocks failed within seven minutes due to an error in the control system, which meant that an output of around 2,100 MW had to be replaced at short notice. This resulted in frequency fluctuations in the power grid , but a power failure could be avoided by using control energy . According to Amprion , the European power grid is able to tolerate an unforeseen failure of up to 3,000 MW of power plant output, so no critical situation has arisen. In the early morning hours of the following day, the two blocks were started up again.

accident

On the evening of October 25, 2007, there was a serious accident on the construction site. A side wall bandage weighing more than 100 tons, part of the large scaffolding, tore off and buried several fitters under them. Three construction workers could only be rescued dead from the rubble of the scaffolding, six others were taken to nearby hospitals, some seriously injured. Almost 300 firefighters, police, medical organizations and technical aid organizations were on duty. In December 2008, the preliminary investigation into negligent homicide was discontinued by the Mönchengladbach public prosecutor. According to the expert opinion, the knot connections of the drum substructure were designed too weakly. Since there was no knowledge of the components - used for the first time in this size - and their stability problems, the accident could not have been foreseen by the experts, according to the public prosecutor. Rather, the design and construction are based on the rules of technology .

Emission limit values

In the approval notice of June 20, 2005, the Düsseldorf district government set emission limit values for the new units F and G, which at the time of application for sulfur dioxide, carbon monoxide and mercury were below the applicable minimum requirements of the 13th BImSchV . Although the daily emission limit value was set comparatively low at 0.0135 mg / m 3 N for the new units (the minimum requirement of the 13th BImSchV provides for 0.03 mg / m 3 N ), this limit value does not yet require any special mercury reduction technology. This can be seen from the fact that the mercury emissions more than doubled after the new units went into operation in 2012 (for comparison: in the USA limit values ​​of 0.005 to 0.0054 mg / m 3 N apply to lignite power plants depending on their efficiency ).

Pollutants with limit values ​​in the daily average are monitored by continuously working measuring devices, the other values ​​by individual measurements. For comparison with the limit values ​​of the new blocks, the limit values ​​of the 13th BImSchV (2004) valid at the time of application are listed as well as the limit values ​​of the current 13th BImSchV (2013) and the emission values ​​that can be achieved in normal operation with the best available technologies , as specified in the information sheet of the European Commission for correspondingly large new plants with pulverized lignite combustion on the basis of the data collection in the years 2001–2002.

The European Commission has been organizing a new collection of data on updated best available techniques (BAT) since October 2011 and is expected to publish new BAT conclusions for large combustion plants in 2014 . In accordance with the European Industrial Emissions Directive, the emission values ​​that can be achieved with BAT specified therein for existing plants must be complied with no later than four years after the publication of the BAT conclusions at the Neurath power plant.

Emissions of pollutants and greenhouse gases

Power plant Critics the high emissions of the power plant Neurath nitrogen oxides , sulfur oxides , mercury and particulate matter , to the cancer -generating substances ( lead , cadmium , nickel , PAK , dioxins and furans ) can adhere. In 2013, a study commissioned by Greenpeace at the University of Stuttgart came to the conclusion that the fine dusts emitted by the Neurath coal-fired power plant (before units F and G were put into operation) and the secondary fine dusts formed from sulfur dioxide , nitrogen oxide and NMVOC emissions are statistically significant 1,712 years of life lost. The power plant ranks 7th on the list of “Germany's most harmful coal-fired power plants”.

All coal-fired power plants are criticized by environmental associations and nature conservationists with reference to climate change . The power generation from brown coal is still one spite optimized technology (Boa) to the technologies of energy which the highest emission of CO 2 having per kilowatt-hour of electricity. The consumption of lignite per BoA ​​block is 820 tons per hour, so a total of 1640 tons.

Although the efficiency is around 43% - a world record for lignite-based power generation - according to RWE, the two new blocks save around 1/4 of the CO 2 emissions compared to old power plants based on lignite , but in absolute numbers the CO 2 emissions are around 16 million Tons per year. Approx. 950 g of carbon dioxide are emitted per electrical kilowatt hour, which is almost twice as much as the average German electricity mix (494 g CO 2 / kWh). For comparison: modern combined cycle power plants such as Unit 4 of the Irsching power plant, which went into operation in 2011 , emit just over 330 g of CO 2 per kWh with an efficiency of 60.4% .

On the list published by WWF in 2007 of the 30 most climate-damaging power plants in the EU, the Neurath power plant was ranked 7th in Europe and 5th in Germany (1150 g CO 2 per kilowatt hour) after the Niederaussem and Jänschwalde power plants . Frimmersdorf and Weisweiler .

It was criticized that the system efficiency is not maximized by additional measures such as combined heat and power . A greenhouse park has been using part of the waste heat since summer 2011 . On 11 hectares z. B. grown tomatoes.

The Neurath power plant reported the following emissions in the European pollutant register " PRTR ":
