What is an Tariff?

A tariff is a method of charging varying fees on your power bill based on use. If you have spent 600 units, for example, you will receive a different fee for each level of unit consumption. You receive little compensation for low levels up to 100 units, a modest increase for a subsequent level up to 200 units, and another meagre increase for levels over 500 units.
