Fordelen ved at følge med i elprisen time for time er, at du får mulighed for at planlægge dig til en billigere elregning. Når du henter app’en kan du se, at der kan være stor forskel på elprisen i løbet af et døgn. Udover at kunne se prisen time for time, så er det ligeledes muligt at se døgnets gennemsnitspris samt højeste og laveste pris per dag. Du skal være opmærksom på, at det er nødvendigt at have en variabel elaftale med dit elselskab for at du kan udnytte de billigere priser på strømmen. Hvis du har en fastpris-aftale, så er prisen den samme uanset hvornår i døgnet du bruger den. Er du i tvivl om du har en optimale elaftale, kan du altid sammenligne de forskellige elselskabers elaftaler ved at indtaste din adresse på Elberegner.dk. Det er både økonomisk og oftest mest klimavenligt at time sit brug til de timer, hvor prisen er billigst. Det kan derfor være en god idé at vente med at sætte sin vaskemaskine, tørretumbler eller andre større ‘strømslugere’ i gang i de timer i døgnet, hvor man kan udnytte en billigere pris. Som udgangspunkt vil du opdage at prisen typisk er dyreste fra kl. 17-21. Grunden til det, er at det er i det tidsrum, hvor flest danskeres forbrug er.
