Daily fee – The distribution network in your area charge a fee per day to be connected to your network, regardless of how much electricity you consume. Ecotricity pass this cost through directly to you, with no extras added on.
Variable charges – The distribution network in your area also charge a fee per unit of electricity you use. With Time of Use (TOU) pricing, this charge can vary depending on what time of day the electricity was used. There are usually peak times, when lots of people are using electricity and the price is high (e.g. at 7.30am, or at dinner time), and off-peak times, when not many people are using electricity and the price is low (e.g. at 2am). Ecotricity also pass these costs directly on to you, with no additions. Each unit of electricity you use, also costs an amount of money, this is associated. Ecotricity buy power for the price at the time of use and again pass this directly on to you. Whatever the real market price is for power at a particular time on a particular day, is what you will be charged for it. Again, you will generally find that when lots of people are using electricity, it is expensive, and vice versa.
