Bill Amount Graph
What does this graph tell me?
This graph gives you an overview of the major components making up your invoice.
It shows:
the total billed amount which comprises energy charges
the network charges for sites / ICPs, or accounts year to date or any period within the last 24 months
how the bill has changed.

Billed Amount is Calculated in the Following Way:
1. Except Residential Customers:
Previous meter reading should be deducted from the current reading.
Difference is multiplied on current transformer ratio.
Resulted kWh is multiplied by tariff.
If by some reason act is written, corresponding kWh and GEL will be added to the billed amount.
If customer meter could not be read by some reason, estimated reading, based on the last month average consumption (and billing period) will be used to estimate consumed kWh. During the next billing cycle, after the meter is read, estimated billing and corresponding amount automatically will be corrected (increased or decreased);

Final account(ing) is the equivalent to (End)abrechnung, which is an oxymoron in itself since Abrechnung is the consummation and concluding act of a business deal.

'Settlement' is the completion of the transaction (that's why we talk about settlement date).

'Tallying' is the compilation of credits and liabilities leading up to the final account

'Squaring up' is the colloquialism for Abrechnung (but not to be used formally)
