When Russia unleashed its illegal and unprovoked invasion of Ukraine in February 2022, gas prices in Europe spiked by a factor of 10, driving a wave of bankruptcies and restructurings of European energy companies. Uniper was one of those. 

Uniper is one of Germany's largest energy companies. It is active across more than 40 countries and has 19.5 GW of power generation capacity to its name. It was one of the funders of the built-but-never-used Nord Stream 2 gas pipeline that connects Russia to Germany and, for most of its history, was heavily reliant on Russian gas. 

So when the gas taps from Russia were turned off, Uniper reported losses of $40 billion — the highest losses in German corporate history — and was subsequently nationalised by the German government. The company has since returned to profitability under its new CEO, Michael Lewis, our guest this week on Cleaning Up. 

Michael Lewis joins Michael Liebreich to discuss the company's rise from the ashes, and how it plans to reach its climate targets and overcome the dunkelflaute.
