Abstract

Outre des informations sur la consommation d'électricité, des informations sur le coût actuel de l'électricité sont également indispensables à une gestion optimisée de l'énergie dans la sphère privée ou commerciale. L'invention présente un procédé permettant de déterminer aussi bien la consommation d'électricité que le coût de l'électricité pour un consommateur correspondant. Ainsi, les informations relatives à la consommation d'électricité sont associées aux informations concernant le tarif de l'électricité en vigueur au moment de la consommation, ce qui permet d'obtenir une indication du coût réel de la consommation d'électricité.
