Appointment: Géraldine BRISSIAUD becomes Chief Executive Officer of Elengy
On Monday morning, 5th January 2026, Elengy's Board of Directors appointed Géraldine BRISSIAUD as Chief Executive Officer.
Géraldine began her career at SUEZ in 2005, holding operational and functional management positions. In particular, she led the operation and negotiation of major public service delegation contracts in the water sector.
In 2016, she joined ENGIE Ineo as Director of the Ile-de-France region, where she managed several large-scale construction and infrastructure projects before actively contributing to the creation of ENGIE Solutions.
Since 2021, she has been Managing Director of Compagnie Parisienne de Chauffage Urbain (CPCU) and has overseen Fraîcheur de Paris — the two largest district heating and cooling networks in Europe. Under her leadership, these entities have embarked on an ambitious transformation to decarbonise the capital's energy infrastructure.
"I am very excited to be joining a strategic infrastructure for the French and European energy system, as well as a thrilling human and industrial adventure. Indeed, after pioneering LNG in France, Elengy is now transforming its terminals into decarbonisation hubs. The challenges ahead are particularly significant and offer great opportunities: they will mobilise all our energy and collective ambition."
