Isabelle Kocher

Isabelle Kocher (: Thabut; born 9 December 1966 ) is a French businesswoman. She was the chief executive officer of Engie (previously GDF Suez) until February 2020.

Early life and education Isabelle Kocher graduated from the École normale supérieure in Paris in 1987 and Mines ParisTech engineering school. She also holds a master's degree in quantum optics and a postgraduate certificate in physics.

Career Public sector From 1997 to 1999, Kocher was director of the postal and telecommunication budgets, followed by the defense budget at the French Budget Department. Between 1999 and 2002, she worked as industrial affairs advisor at the office of French prime minister Lionel Jospin.

Private sector She joined the Suez company in 2002 and held functional and operational positions. She was running its French water operations when it became GDF Suez in 2008. Kocher was then elevated to finance director and operations director.

She was appointed in 2011 as chief financial officer of GDF Suez. Between October 2014 and April 2016, she served as deputy CEO and chief operating officer.

CEO of Engie, 2016–2020 On 3 May 2016 Kocher was appointed CEO of Engie, replacing Gérard Mestrallet. She became the only woman CEO in the CAC 40 index.

Since becoming CEO, Isabelle Kocher initiated a strategic shift at Engie aimed at repositioning the company within the global energy sector.

Additionally, Kocher prioritized diversity and internationalization within the company. Under her leadership, Engie set targets to increase female representation, aiming for women to hold at least 25% of executive roles and 35% of high-potential positions.

In 2019, after having invested €15 billion in new activities, Kocher announced the definitive exit of coal activities and a new strategic plan for the years 2019-2021. Her plan is to specialize in high value-added services and in renewable energies. She planned to invest another €12 billion in these activities, partly financed by the sale of €6 billion assets (including the last coal plants). She also announced her intention to leave 20 of the 70 countries where Engie is active, and focus the group's activities on 20 countries and 30 metropolitan areas, mainly in Southeast Asia and Africa.

By the end of 2019, Kocher came under pressure amid reports of a strategy split within the group and disagreements between board members on whether to pursue a sell-off of some gas assets. She subsequently failed to get state backing to serve another term.

On 6 February 2020 it was announced that her mandate as CEO would not be renewed and that new leadership was needed at the head of Engie.

Since 2020 In 2021, she co-founded Blunomy, a company focused on supporting the energy transition and decarbonization strategies, where she serves as Executive Chair.

Other positions She is member of the board of Suez, Axa, International Power and Investor AB. She is chairman of Terrawatt Initiative, a global non profit-organization designed to implement a new global energy mix along 3 axes:

deploying modern technologies to replace the old power grids, incapable of handling a significant increase in renewable energy providing for the world’s needs in energy in developing countries, by deploying new renewable assets withdrawing from fossil energy in developed countries, by replacing old assets with clean and renewable energy.

Terrawatt's goal is to present ready-to-implement propositions at COP 23.

In September 2017, she was ranked third in Fortune's international list of most powerful women.
