Direct current networks: the CRE launches a working group looking to 2040
Announced on 10 July 2026, this group will bring together around fifty experts to analyse the conditions for deploying direct current.
On 10 July 2026, the Foresight division of the French Energy Regulatory Commission launched a working group dedicated to the development of direct current networks looking ahead to 2040.
Electricity comes in two main forms: direct current and alternating current. The latter has prevailed since the end of the 19th century, notably thanks to its ability to change voltage easily, which makes transmission and distribution more practical and economical.
Direct current nevertheless retains advantages, particularly for transporting large quantities of electricity over very long distances. These advantages raise the question of its development in the medium and long term.
The working group will analyse the conditions for developing direct current networks at high, medium and low voltage above 100 kVA by 2040, as well as their integration into the power system. It will examine economic and technical aspects in order to formulate concrete recommendations.
Around fifty experts will take part. It will be co-chaired by Hubert de la Grandière, chief executive of the Supergrid Institute, and Marc Petit, professor at CentraleSupélec.
