Assystem in France

In France, Assystem is supporting energy transition projects by providing engineering services and digital solutions and services in multiple sectors: nuclear, renewable energies, hydrogen, electricity networks, transport, cities and regional development.

Founded in 1966 to support EDF in the implementation of France's nuclear power plants, Assystem now supports nuclear projects throughout their life cycle. We are one of the top three nuclear engineering companies in the world. Our experts benefit from key engineering expertise and digital skills for the benefit of the nuclear fleet's maintenance, the extended operation of reactors currently in service, and the construction of new EPRs.

We oversee numerous projects for the implementation of the Grand Carénage (major refit) programme, and we are involved in the Flamanville EPR facility and the EPR2 programme. We are also involved in the future of nuclear power: we have signed a partnership with NAAREA for the development of an XSMR (Extra Small Modular Reactor), and we are contributing to the ITER undertaking through project management and engineering missions.

In addition to providing its nuclear power expertise, Assystem supports the deployment of renewable energies. To fulfil its objective of doubling renewable electricity production by 2030, France has initiated a number of offshore wind projects. In this respect, Assystem oversaw HSE compliance during the construction phase of one of these future wind farms.

Assystem also participates in the decarbonisation and electricifcation of the transport sector. Our teams have carried out studies and provided project and PMO support for projects develop hydrogen as a source of energy for the in the rail, waterway, and road transport sectors.

We also apply our engineering and digital expertise to projects for the modernisation, maintenance, and extension of the French rail network.

Several leading French industrial groups have put their trust in us: EDF, the French Alternative Energies and Atomic Energy Commission (CEA), Framatome, Orano, RATP, Société du Grand Paris, SNCF Réseau, Thales, among others.
