Pay on Time Discount
Receive a discount on your energy usage charges for paying your bills on time.
This discount does not apply to supply charges, or fees.
So a bit of reverse engineering (maths) shows that the usage component of your bill is $102.18
or ($22.48 * (100/22))
It would appear that you had $222.54 of supply charges and fees.
