Context and challenges


The transformations in electricity production methods generated by the energy transition and the development of a decarbonised energy around the world have a direct impact on the construction and operation of grids.  The electricity demand is increasing to cope with demographic, industrial and economic growth of countries. This trend, which will last for a long time, has had a significant impact on the management of local power systems. And beyond the level of production necessary to meet this demand, the transformations of the ways to produce zero-carbon energy are disrupting the existing energy mix and has direct consequences on grids.

Optimising networks to the growing demand for electricity

A growing consumption of electricity due to the increasing urbanisation of the world population or the industrialisation of regions requires adaptations to the grids, which transport this electricity from production plants to delivery stations. Modernisation, resilience to energy demand peak and supply continuity are the main challenges for tomorrow’s electricity networks.

Integrate zero-carbon energy into the grids

Continue the development of nuclear and integrate renewable energies are the key of a decarbonised energy mix. But their integration into the grids is not without effect and must be managed to avoid destabilisation of electrical networks (variability of renewables or the location of plants are major aspects in the equation).

Adapting to the grid regulatory constraints of each country

The electrical network regulations are different according to the continents and can even vary significantly between neighbouring countries. Respecting local norms and standards to build or modernise the grids is thus also a major challenge for electrical operators.

Our expertise in Grids


Assystem Stup’s expertise for more than 50 years in nuclear and power sectors allows us to master the practices and standards to be integrated for the management of an electrical network.
Our engineers have strong competences in transmission and distribution, power system analysis and simulation, grid impact studies, engineering studies, and requirements management, and are used to deal with projects from beginning to end:
• Consultancy & Project Management
• Siting, permitting & environment
• Feasibility, conceptual to tender design
• Detailed design and specification of new installations
• Standards assessment and validation

Assystem Stup’s expertises also lies in its capability to assist operators in the globality of their project: our teams will be able to contribute to the development of new nuclear power plants, to the implementation of renewable projects and to guarantee their optimal integration to the grids in terms of transport and distribution.
