Vattenfall chief financial officer Stefan Dohler will leave the Swedish utility to become chief executive at German regional utility EWE.

“It is with mixed feelings that I have decided to leave Vattenfall after almost 20 years. Vattenfall has formed my professional life and offered me tremendous opportunities to develop,” Dohler says.

Dohler had joined Vattenfall in 1998 and served in various senior management positions before becoming the company’s CFO in December 2016.
