    Coal still has an important role to play as part of a reliable and cost-effective energy mix.

    We operate nine coal-fired power plants along the Rhine and Ruhr rivers and in the Saarland, and another three abroad. We also have a refinery power plant in Germany. By continually optimizing our plants, we are able to extract energy from coal more economically and flexibly than ever before.

    Some of our plants produce thermal energy in addition to electricity using the combined heat and power generation principle. This method makes especially efficient use of valuable coal resources.

    In addition, we plan, finance and construct hard coal fired power plants and also provide operation and maintenance (O&M) services for plants on behalf of third parties.

    Coal is a fossil fuel. The black, hard sedimentary rock is formed from the remains of prehistoric plants that have become chemically altered and enriched with carbon dioxide over millions of years in the absence of air.
