Birth of a Key Player in the energy transition

Omexom, the VINCI Energies brand dedicated to energy transition, is positioned across the entire value chain, from generation to transmission and distribution grids and the final consumer’s meter.

Omexom began in 2000 when 20 regional business units specialising in electricity transmission and transformation in France adopted the common Omexom banner. A major turning point was reached in 2010 with the extension of Omexom’s field of activity and its international expansion. Broadening its range of services, Omexom branched out into generation and distribution services and positioned itself across the entire electricity value chain. Since then the brand has continued to expand. Today our international network brings together 425 business units.
