Energy tariffs explained | Alinta Energy
A tariff is how much you''re charged for your energy consumption. It''s not always a single rate. And it''s not one-size-fits-all. Instead, your tariff is determined by the type of meter you have and your energy distributor. (One thing to remember: Alinta Energy is a retailer, not a distributor, so we don''t set your tariff.
