Our main fields of activity



Nuclear Power



To meet the growing need for energy, particularly electricity, while ensuring reliable processes that comply with environmental standards that limit carbon emissions, the electricity and steam production sectors for industry must face many technological challenges.
TES supports its clients in the management of major projects in France and around the world, providing expertise in Basic Design (detailed studies), BOP (Balance of Plant) of pipelines and electrical networks, as well as in the coordination of the assembly and commissioning of installations.
TES participates in national (France) and international (UK, China, Finland) programmes for the development of new nuclear generation facilities, as well as programmes to extend the life of existing plants.


Historically, TES has always participated and supported its clients on their major new construction or revamping projects. 

TES is a gateway for feedback to enrich new projects and thus contribute to their success in terms of cost and reliability. 

TES also provides the interface during studies and commissioning with specialists in new technologies related to information systems or digital engineering, as well as for fields related to functional safety and operational reliability of installations.


TES has always had a strong relationship with the shipbuilding industry. 

TES participates in MRO (Maintenance, Repair and Operations) projects in the mechanical, electrical and automation fields.

"T.E.S. is familiar with the techniques and specificities of our businesses and has met our expectations within the deadlines set. Its availability, responsiveness and highly qualified staff have been essential in carrying out their missions. The T.E.S. teams have broad skills enabling them to carry out a global mission ranging from supervision of assembly to commissioning of on-site installations. I would also like to highlight their high adaptability to a foreign working environment. »
