4 A good mix is necessary Big means affordable The right location Better for the environment
Energy from wind, sun and water power – can’t these cover all our energy needs? Unfortunately, the sun doesn’t shine every day, and the wind takes days off, too. The potential to generate power using hydroelectric dams has been largely exhausted in Germany. Hard coal-fi red power plants are still needed alongside other power generation methods in order to guarantee an affordable and secure supply. This is why E.ON is focusing on a balanced energy mix. The new Datteln 4 hard coal-fi red power plant is a part of this strategy. >> See page 6 for more on this topic Size provides a cost advantage in power generation. The higher the output of a power plant, the more affordable it is to operate, allowing us to sell power more cheaply. A high degree of effi ciency can be realized in large power plants. Today, we are able to generate twice as much electricity from one kilogram of hard coal as we were 50 years ago. This means lower emissions and a more careful use of resources. For this reason, large power plants will contue to form the backbone of our power generation capacity in the future. >> See page 7 for more on this topic Regions with a high population density – like the Ruhr area – need a lot of energy. However, it is not possible to store large amounts of electricity. We need to generate it exactly when it is needed. In addition, coal-fi red power plants require a strong logistics infrastructure, which is present at the Datteln location thanks to the present power plant facilities Datteln 1 through 3. These will be replaced by Datteln 4 because they have reached the end of their technical and economic lifetime. This means that this new build project will enable us to retain important jobs in the region for the coming decades. >> See page 12 for more on this topic The new power plant will have a net electrical effi ciency of over 45 percent. The simultaneous extraction of district heat means that over 60 percent of the potential energy in the fuel can be utilized. Datteln 4 will replace not only the existing power plants in Datteln, but another old facility in the Ruhr area as well, and E.ON has already shut down 1,800 MW of fossil-powered power plant output there. Even though the facility produces signifi cantly more energy than its predecessors, it will improve the region’s environmental footprint signifi cantly. The key is the improved efficiency and the decommissioning of the old, less efficient facilities. The new power plant will have a modern, multi-step fl ue gas purifi cation system. This will remove nitrogen oxides, dust and sulfur from the fl ue gas – and to a greater extent than what is currently required by law. The state environmental authority verifi es that the emission limit values are adhered to around the clock, 365 days a year. >> See page 14 for more on this topic 5
