Uniper SE is an energy company based in Düsseldorf, Germany. The name of the company is a portmanteau of “unique” and “performance” given by long term employee Gregor Recke. Uniper was formed by the separation of E.ON’s fossil fuel assets into a separate company that began operating on 1 January 2016. The company employs about 11,000 employees in over 40 countries. Around one third of the employees are based in Germany. It owns a subsidiary company in Russia called Unipro. Uniper is listed at the Frankfurt Stock Exchange. Its largest shareholder is the Finnish energy company Fortum with a 49.99% stake. The company has faced criticism for opening new coal fueled power plants in Germany as recently as May 2020.
