The Voerde power plant is a hard coal-fired power plant in Voerde (Lower Rhine) in the Wesel district that has been closed since the end of March 2017 . It is right on the Rhine .
history
In 1970/71, the West power plant with two blocks (West I and West II) with 322 and 318 MW electrical output without flue gas cleaning systems was built at the Voerde location , which at that time was technically feasible but not yet required by law.
In 1982 and 1985 the Voerde location was expanded to include the Voerde A and Voerde B units, each with 695 MW electrical output, which were equipped with a flue gas desulphurisation system (FGD) , which is now required by law .
In December 2005, a new FGD with a newly built chimney was put into operation in order to still be able to comply with the stricter legal limit values despite the outdated power plant units. Since the construction of a third chimney was cheaper, the additional use of the 165 m high natural draft cooling tower for the discharge of clean gas (use of the cooling tower as a chimney) was not realized in 2005 for cost reasons. If the cooling tower had been converted (introduction of the flue gas pipe in the center of the cooling tower), a chimney would no longer have been necessary for blocks Voerde A and B. In addition, the renovation in 2005 also increased the total output of the power plant by 114 megawatts (West I and II 6 MW each, Voerde A and B 51 MW each).
In autumn 2015, RWE, as a 25% shareholder, asked STEAG to take the two power plant blocks (Voerde A and B) off the grid by the end of September 2016. RWE justified its request with the low wholesale prices. March 31, 2017 was set as the shutdown date. In January 2017, STEAG announced that it would also shut down Units West I and II at the same time. The power plant was shut down on March 31, 2017.
Dismantling and future of the power plant site
The dismantling of the power plant is currently expected to take five to seven years. The city is considering marketing the area gained as a residential area directly on the Rhine.
Technical specifications
The four power plant blocks (West I and II, Voerde A and B) together had an installed capacity (gross capacity) of 2234 megawatts (see table). It was the largest power plant of the operator Steag .
With an electricity production amounting to 11,000 GWh , the entire system consumed approx. 4 million tons of hard coal. A coal store next to the power plant with a capacity of 350,000 tons compensated for fluctuations in delivery and consumption.
The usable electricity output in 2007 was 10,991 GWh. In 2010 only 8,414 GWh were generated due to the changed conditions on the electricity market. produced. In 2011, electricity production fell again to a total of 7,521 GWh.
The Voerde power plant has a 250 meter high chimney (out of operation since 2005), a 230 meter high chimney (new construction 2005) and a 218 meter high chimney. The 230 meter high chimney was rebuilt in the period 2004/2005 as part of the partial renovation of the flue gas cleaning system in order to meet the requirements of the 13th Federal Immission Control Ordinance amended by the legislator . The 218 meter high chimney belonged to blocks West I and West II, the 230 meter high chimney (new building 2005) was used by blocks Voerde A and B and replaced the old 250 meter high chimney. The now no longer needed 250 meter high chimney was only closed at the top, the old flue gas pipes of blocks A and B were diverted to the new chimney. A dismantling of the inactive chimney was not planned for cost reasons.

The grid connection was made via the Möllen substation to the power grid of the transmission system operator Amprion . The West I and II blocks feed into the 220 kV maximum voltage level and the Voerde A and B blocks feed into the 380 kV maximum voltage level.
State road 396, which connects Voerde with Dinslaken and Duisburg- Walsum , runs through the power plant site .
In 2016, 180 employees worked in the power plant, spread over the Voerde A & B (110 employees) and West I & 2 (70 employees) blocks.
The power plant is also a location on the themed route “Large-scale chemistry and energy” on the Route of Industrial Culture .
Emissions
Air pollutants and water pollutants
Coal-fired power plants are criticized for their pollutant emissions. Even after the installation of filter systems in the 1980s, which remove most of the sulfur from the exhaust gases, coal-fired power plants continue to emit relevant amounts of sulfur dioxide . In addition to sulfur dioxide, nitrogen oxides , which are harmful to the environment and health, as well as fine dusts that are harmful to health , the heavy metals and PAHs they contain, enter the environment. In Germany, the energy industry contributed 71% (6.571 tons) to total mercury emissions in 2010 .
The pollutant emissions of all large industrial companies are published in the European Pollutant Emissions Register (PRTR) via the German portal www.thru.de.
Emissions below the reportable quantity threshold are listed in the table with "<" next to the limit value.

Economic costs due to environmental and health damage
The European Environment Agency has calculated the economic costs of damage to the environment and health of the approximately 28,000 largest industrial plants in Europe on the basis of the emission data reported in the PRTR (reporting year 2009) as part of a scientific study.
In addition to the emission data from the European Pollutant Release and Transfer Register, the calculations were based on further epidemiological studies on the health effects of fine dust. In addition, costs for the treatment of diseases caused by the released pollutants and the loss of work due to these diseases were calculated. This study was commissioned by the EU Commission, the damage costs for the power plant blocks West I & II and Voerde A & B were calculated separately.
Reporting year | cause | Damage costs per year | unit |
---|---|---|---|
2009 | Voerde power plant (Blocks West I & II) | 84-137 | Million Euros |
2009 | Voerde power plant (Voerde A & B blocks) | 183-272 | Million Euros |
2009 | Voerde power plant (total amount of Voerde power plant) | 267-410 | Million Euros |
2009 | Power plant Voerde (share of power plant Voerde in total) | 0.26-0.24 | percentage |
2009 | Total about 28,000 industrial plants in Europe | 102,000-169,000 | Million Euros |
