Understanding Your Electricity Bill

Learning to read your electricity bill is essential to understanding how your monthly charges are calculated. Your electricity bill is a multi-purpose document that provides details on your energy consumption pattern. It also helps you to track changes in specific areas such as the fuel surcharge, allowing you to see how this factor affects your charges.

The electricity bill also provides you with general information about your contract for service.
Let's take a closer look at some of its features:

On the top left hand corner, you will notice Previous Balance - This information shows the amount on your previous bill.


- This amount represents payments made following your last bill and before processing this current bill

Balance brought forward

- Represents any outstanding amounts or credits from the previous bill. If your bill is paid after the next bill is prepared, the previous balance will re-appear on the bill. Customers should not be too concerned if they see a balance brought forward from the previous month if this amount has already been paid. The arrears that appear on your electricity bill is not an error, it appears on your bill because your account was updated after the payment due date on your electricity bill.

- Customer areas are divided into sizes (cycles) suited for daily billing operation. The first 2-digit number denotes the billing cycle area and the second 2-digit number denotes the meter reading route.
