How it started
History
RTE was formed as a result of European Directive No. 96/92/EC of December 1996, which directed that at least 26% of member countries' electricity sales be open to competition, and became law in France in February 2000. The directive required France to liberalise its electricity market by unbundling its generation and transmission activities, which until then had been fully controlled by EdF. RTE was established in July 2000 as a division of EdF, with a public charter to guarantee equitable access to its electricity market, and to secure the continuity and quality of electricity supply.
Further legal acts in July 2004 and August 2005 enforced the legal separation of RTE from EdF, transforming it into a limited liability subsidiary, and granted it trademark rights to its logo and the name Réseau de Transport d'Électricité.
