Vattenfall spent two and a half years and €70 million ( million) building the plant alongside the 1,600MW coalfired Schwarze Pumpe power plant in north Germany (Figure 5).
This involves the simultaneous milling and drying of raw coal immediately before combustion in a beatertype mill, aerated by the hot flue gas drawn off at 900 1000°C from the upper levels of the furnace chamber. Such predrying requires a boiler substantially larger to cope with the large quantity of evaporated water.

In February 2022, Vattenfall decided to not place any further orders of Russian coal and to phase out Russian coal completely. The last delivery arrived end of March 2022 and none of the two plants in Berlin run on Russian coal anymore. As a result, the share of coal from Russia decreased from 85 percent in 2021 to 28 percent for 2022 as a whole.
Vattenfall is the sole operator of five opencast lignite mines Jänschwalde, Nochten, Reichwalde, WelzowSüd and Cottbus Nord in the German Lusatia region (in Germany's eastern states of Brandenburg and Saxony).
