How is the bill estimate calculated?

We use data collected from a sample of our customers, across all states in which we operate, and who have been with us for at least 9 months. We have calculated the total energy costs  of similar households from the hundreds of thousands of customers sampled and divided that sum by the total number of customers. Using that as a base we have calculated the approximate energy costs for similar households for each month/quarter.

We then apply the rates for your zone, service charges, and any discounts which come with the plan you select. All these can differ from area to area, state to state, and in some cases even from winter to summer.

The simple part is that we do all the calculating. Our aim is to provide you with an indication of what customers of similar households living in your area could expect to pay on average per month/per quarter. It should not be used as an official quote. The amount you actually pay will be based on your individual energy usage.
