Welcome to the world of electricity networks and storage.


“Smart grids are the essential support for the energy transition, with the integration of renewable energies and the electrification of uses. Piloting electrical systems on different scales, more dynamic and more resilient by using flexibilities, or supporting the electrification and integration of new energy uses into electrical networks, are all challenges to be taken up by EDF R&D.”

Nicolas Vandenberghe, Director of the R&D Electricity Network Programme.

Electricity health check

Since Edison and Tesla, the electricity signal has deteriorated over time. Our daily uses, which involve more and more electronic and electrical devices, modify the phase difference of the signal and affect the original quality of the electricity. To adapt, EDF R&D is contributing to drafting new standards and building the network of tomorrow, even smarter and more flexible.

The supply/demand balance

A nuclear power station usually has 2-4 reactors that are divided into nuclear units of an average unit power of 1,000 MW (in this case, they generate 2,000-4,000 MW of accumulated power). In France, there are 58 active nuclear reactors. They are located in 19 power stations)
