    The share of controllable energy generation based on conventional energy sources is continuously decreasing in the course of the energy transition, while the share of renewable energies in the electricity mix is steadily increasing. Nevertheless, conventional power plants will still be needed in the future to ensure the necessary security of supply for Germany as an industrial nation on its way to a largely emission-free energy future.

    We are taking responsibility and have reduced our own domestic CO2 emissions by almost 85 percent from 1990 to the present. But that's not all: up to and including 2022, four more power plant units at the Bergkamen, Herne and Völklingen-Fenne sites will be shut down. After that, only our highly efficient coal-fired power plant of the latest generation in Duisburg-Walsum will be in operation.

    At the same time, the construction of one of the world's most modern combined-cycle gas turbine power plants at the Herne site will not only secure the regional district heating supply in the Ruhr area, but will also significantly reduce CO2 emissions in the middle of the Ruhr area by switching fuel from hard coal to natural gas. Even the use of green hydrogen is possible in the plant in the long term.

    In addition, STEAG plans, realises and operates power plants and plants for energy generation on behalf of third parties (operational management). In Germany, for example, these include the young Trianel hard coal-fired power plant in Lünen in North Rhine-Westphalia and the TotalEnergies refinery power plant in Leuna.

    Power Plants in Germany

    Duisburg-Walsum Power Plant

    The combined heat and power plant in the western Ruhr area generates electricity, heat and process steam.


    Herne Combined Heat and Power Plant

    The Herne combined heat and power plant uses hard coal to generate not only electricity, but also district heating.


    Bergkamen Power Plant

    STEAG operates the hard coal fired power plant in Bergkamen in the eastern Ruhr area.


    Völklingen-Fenne Power Plant

    There are several plants at the Fenne site, which is located between Saarlouis and Saarbrücken.


    Weiher Power Plant

    The Weiher hard coal fired power plant is located in Quierschied, to the north of Saarbrücken.


    Bexbach Power Plant

    The hard coal fired power plant in Bexbach is currently the largest unit-type power plant in the Saar region.



    Leuna Refinery Power Plant

    The Leuna refinery power plant supplies the local refinery with electricity, process steam and compressed air.


    Power plants abroad

    Iskenderun Power Plant, Turkey

    Not only is STEAG's hard coal fired power plant in Iskenderun (Turkey) the biggest investment project in the history of STEAG, it is also one of the biggest foreign investments in Turkey to date.


    Termopaipa Power Plant, Colombia

    The Termopaipa hard coal fired power plant located near the town of Paipa (Colombia) was the first power plant abroad planned, financed and built by STEAG.


    Mindanao Power Plant, Philippines

    STEAG's third foreign power plant is located in the north of the Philippine island of Mindanao and supplies the 22 million inhabitants of the second largest island in the Philippines with electricity.


    Decommissioned power plants

    Voerde Power Plant

    STEAG operated two power plants at the Voerde site on the Lower Rhine: Voerde and West, each with two units. Both power plants have been shut down since March 2017.


    Lünen Power Plant

    At the Lünen site, STEAG GmbH operated a two-unit hard coal fired power plant. On 31.12.2018 the power plant was finally taken off the grid.


    Duisburg Walsum Power plant unit 9

    Power plant unit 9 at the Walsum site was shut down around July 2021.
