By his own admission, Klaus Müller has been „in crisis mode“ for a long time. He took up his new post on March 1 – Russia had just invaded Ukraine. „It was clear right away that energy supply would be the most urgent issue. A crisis was looming,“ says the 51-year-old. As the new president of the Federal Network Agency, he originally wanted to take care of a booster for renewable energies, the expansion of the power grid and a lot more. But the biggest challenge at the moment, of course, is to avoid a gas shortage and get the country safely through the winter.
