Bill Details

First reading date
Refers to the date on which the meter indicator was determined in the previous billing period, and is accepted as the start date of the new bill.

Last reading date
Refers to the date on which the meter is read for the billing purposes in the new billing period.

First indicator
Refers to the indicator value read from the meter in the previous billing period.

Last indicator
Refers to the last indicator value read from the meter in the new billing period.

Consumption (m³)
Refers to the natural gas volume passing through the meter between the previous and new reading dates. Refers to the difference between the first indicator and the last indicator.

Correction coefficient
Applied by calculating the correction coefficient in order to determine the actual natural gas amount used in different pressures. The coefficient changes monthly.

Corrected consumption (m³)
Calculated based on pressure temperature, compressibility factors. Corrected consumption refers to the actual amount of natural gas passing from the meter in volume, and obtained by applying the correction coefficient to the consumption value.

Average upper calorific value (kcal/m³)
Refers to the amount of energy obtained as a result of the combustion of 1 m³ of natural gas, and varies according to the state of the mixture. You pay your bill according to the daily average of different coefficients. The ratio of actual average upper calorific value to the standard value refers to the actual amount of energy consumed based on the standard value taken as 9.155 kcal/m³. In this way, unlike other fuels, you pay based on the actual amount of natural gas used.

Amount of energy consumed (kWh)
Refers to the actual amount of natural energy passing through the meter in energy, which is calculated based on pressure, temperature, compressibility factors. It is obtained by applying the correction coefficient and the average upper calorific value to the consumption value.

Average sales price (TL/kWh)
1 kWh energy equivalent refers to the average sales price of natural gas. It is the day-weighted average of different tariffs in the billing period.

Consumption price (TL)
Refers to the VAT excluded bill amount that is calculated based on the amount of energy consumed.

VAT (%)
Refers to the value added tax applied to the consumption price.

Discount/Addition (TL)
Refers to the discount/addition amount applied to the previous bill and reflected to the last bill.

Rounding (TL)
It refers to the rounded figure applied in the last bill and reflected on the next bill.

Special service charge (TL)
Refers to the cost of services provided upon the request of the subscriber, excluding value added tax. Services such as temporarily stopping (opening-closing) the natural gas supply, re-supplying, and if there is improper use, the relevant price is added to this category.

Delay fee (TL)
Refers to the surcharge applied to payments made after the due payment date of previous billing period.

VAT (%)
It refers to the value added tax fee applied to the illegal usage and delay fees.
