France plans to invest 30 to 40 billion euro by 2035 in an [[electric road|electric road system]] spanning 8,800 kilometers that recharges electric cars, buses and trucks while driving. Two projects for assessment of electric road technologies were announced in 2023. Three technologies are being considered: [[ground-level power supply]], [[Inductive charging#Transportation|inductive charging]], and [[overhead lines]]. Ground-level power supply technologies, provided by [[Alstom]], Elonroad, and others, are considered the most likely candidate for electric roads. Inductive charging is not considered a mature technology as it delivers the least power, loses 20%-25% of the supplied power when installed on trucks, and its health effects have yet to be documented. Overhead lines is the most mature technology, but the catenaries and overhead wires pose safety and maintenance issues,<ref>{{citation |url=https://www.lemoniteur.fr/article/mobilite-electrique-2-5-une-fenetre-etroite-pour-brancher-les-autoroutes.2203237 |title=Sur les routes de la mobilité électrique |author=Laurent Miguet |date=April 28, 2022 |website=[[Le Moniteur des travaux publics et du bâtiment|Le Moniteur]]}}</ref> and motorway companies find overhead lines too expensive.<ref>{{citation |url=https://www.usinenouvelle.com/article/les-autoroutiers-divises-sur-les-solutions-a-mettre-en-place-pour-faire-rouler-des-camions-electriques.N2208923 |title=Les autoroutiers divisés sur les solutions à mettre en place pour faire rouler des camions électriques |author=Marc Fressoz |date=May 9, 2024 |website=L'USINENOUVELLE.com}}</ref>

A working group of the [[Ministry of the Ecological Transition (France)|French Ministry of Ecology]] recommended adopting a [[Ground-level power supply#Electric road systems|European electric road standard]] formulated with Sweden, Germany, Italy, the Netherlands, Spain, Poland, and others.<ref name="FR-1">{{citation |archive-url=https://web.archive.org/web/20211021080727/https://www.ecologie.gouv.fr/sites/default/files/GT1%20rapport%20final.pdf |archive-date=October 21, 2021 |url=https://www.ecologie.gouv.fr/sites/default/files/GT1%20rapport%20final.pdf |title=Système de route électrique.

[[Vinci SA|Vinci]] will test two electric road systems (ERS) from 2023 to 2027. Both technologies will initially be tested in laboratory conditions, and upon meeting the test requirements they will be installed along 2 kilometers each on the [[A10 autoroute]] south of Paris. Wireless ERS by [[:he:אלקטריאון וירלס|Electreon]] will be tested for durability under highway traffic, and will attempt to reach 200&nbsp;kW of power delivery per truck using multiple receivers. [[Ground-level power supply#Electric road systems|Rail ERS]] by Elonroad, which supplies 350&nbsp;kW of power per receiver, will be tested for [[Skid (automobile)|skid]] effects on [[motorcycle]]s. Both systems will be interoperable with cars, buses, and trucks.<ref>{{citation |url=https://www.usinenouvelle.com/editorial/l-instant-tech-vinci-teste-la-recharge-par-induction-et-par-rail-sur-autoroute.N2158317 |title=Vinci teste la recharge par induction et par rail sur autoroute |author=Léna Corot |date=August 30, 2023 |website=L'USINENOUVELLE.com}}</ref>
