History
RTE was formed as a result of European Directive
A directive is a legal act of the European Union that requires member states to achieve particular goals without dictating how the member states achieve those goals. A directive's goals have to be made the goals of one or more new or changed na ...
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
An electricity market is a system that enables the exchange of electrical energy, through an electrical grid. Historically, electricity has been primarily sold by companies that operate electric generators, and purchased by consumers or electr ...
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

operates at voltages of 63 kV, 90 kV, 150 kV, 225 kV and 400 kV. RTE deems the 63 to 150 kV circuits to be "high voltage" and the 225 kV and 400 kV "extra high voltage". As of the end of 2006, there were of transmission lines interconnecting 2,490 substations. Most of the transmission network is carried on 77,544 route-kilometres (48,180 mi) of overhead power line

RTE's network interconnects with those of its counterparts in most of France's neighbouring countries, and the international trade (both import and export) of electricity is a major contribution to RTE's business activities.
