This graph shows the amount of electricity used (expressed as a unit of electricity) so you can more clearly determine how much more, or less, electricity you are using compared to your last bill and the same period last year (depending on supply period).

You can see how many units (kilowatt hours) you have used on average each day.

Every customer pays a daily supply charge. The supply charge depends on the tariff you are on.
