ENGIE is a French multinational electric utility company, headquartered in La Défense, Courbevoie, which operates in the fields of energy transition, electricity generation and distribution, natural gas, nuclear, renewable energy and petroleum.

It is one of the few players in the sector to develop expert skills in both upstream (engineering, purchasing, operation, maintenance) and downstream (waste management, dismantling) activities.

The company, formed on 22 July 2008 by the merger of Gaz de France and Suez, traces its origins to the Universal Suez Canal Company founded in 1858 to construct the Suez Canal.

As of 2018, ENGIE employs 158,505 people worldwide with revenues of €60.6 billion.

ENGIE is listed on the Euronext exchanges in Paris and Brussels and is a constituent of the CAC 40 and BEL20 indices.

ENGIE was headed from 2016 to 2020 by Isabelle Kocher, who has strongly transformed the company since 2016, notably by deciding to exit coal activities and by investing massively in renewable energies and energy transition services.

During its General Meeting on 14 May 2020, ENGIE’s Board of Directors has approved its purpose statement which is "to act to accelerate the transition towards a carbon-neutral economy, through reduced energy consumption and more environmentally-friendly solutions"[
