When Kocher took over as CEO of French energy giant Engie in May 2016, she launched a three-year strategic plan to reduce its reliance on fossil fuels and boost the share of renewable energy in its portfolio. She shaved a year off of that timeline, completing in June 2018 the company’s portfolio rotation program with roughly $20 billion in announced divestments, including the $1.8 billion sale in July 2018 of its upstream liquefied natural gas business to French oil and gas company Total. At the same time, Engie has invested in more renewable energy sources. In January 2018, for instance, it bought a majority stake in Electro Power Systems, which sells systems for storing hydrogen-based power. In early 2018, the board of Engie decided to keep separate the CEO and chairman roles, dealing a setback to Kocher who had reportedly sought to combine them.
