The two remaining units were fully decommissioned in September 2021[1] The first power station in Frimmersdorf, fired with lignite, was established in 1926 and had an output of 10 MW.

In 1936 the power station was acquired by RWE and after extension work the output raised to 26 MW.

After World War II demolitions the power station was back in operation 1946.

In 1954 this was replaced with a much larger plant Frimmersdorf II which initially contained two 100 MW units.

1988 saw the installation of Flue-gas desulfurization scrubbers, while the two 100 MW units were shut down on 30 June.
