IIRC there was a $10./mo 'Service fee' listed on each bill, which dropped off when I went off the averaging program. That 'Fee' being the reason that I left the program.Where does the information about the $10 monthly fee come from? I don't believe there is a monthly fee for AMB plan, it would have to show on the billing statement and doesn't.
This is how OG&E calculates the AMB bill, I suppose "any current charges" COULD mean fees, but more likely means late fees, reconnect charges, etc. Those would have to be itemized on the bill, in any case.
>>For Average Monthly Billing (AMB), we total your electric bills for the previous 11 months, any current charges, and your current month electric bill are added together; and then divide that total by 12 to determine average monthly bill. Each month, we recalculate the total, using the same formula, so your average may vary slightly month to month.<<
