(6) If the final customer does not allow access to the measuring equipment at the time of deduction of the quantity of gas collected and does not provide data on the measured amount of gas to the operator of the relevant system within 3 days of the date of deduction, the gas consumption shall be calculated as set out in Annex 2.
(7) If the quantity of gas actually collected cannot be determined due to the failure of the measuring equipment, the quantity of gas collected shall be calculated on the basis of the quantity of gas delivered during the same period of the last year. If consumption cannot be determined in this way, the quantity of gas delivered shall be determined retrospectively by subtracting the quantity of gas obtained in the following comparable period. This method of calculating the amount of gas collected is used only for final customers with an annual or 18-month deduction period. For other final customers and gas undertakings, the quantity of gas delivered shall be calculated in a manner agreed in the gas supply contract.
Transmission stations
(1) Transmission stations shall be equipped with at least:
(a) the main and back-up measurement of the quantity of gas supplied with the evaluation and the possibility of conversion into energy transmitted on the basis of gas quality data obtained either directly at the transmission station or at the gas quality monitoring site; the measuring equipment shall be dimensioned according to the flow curve, sampling seasonality and minimum gas flow;
(b) the main closing fittings at the entrance and exit of the transmission station.
(2) If the transmission station is equipped with a gas quality measuring device, a minimum measurement shall be carried out
(a) the composition of the gas for the calculation of GCV, density and Wobbe number;
(b) dew point of water and hydrocarbons;
(c) sulphur and sulphur compounds content at border transfer stations.

Annex No 1 to Decree No 251 / 2001 Coll.
Principles for conversion of volume units into energy
1. The basis for charging the gas supply between the supplier and the customer is the supplied amount of energy. This amount of energy is the product of the average gross calorific value for the accounting period and the delivered gas volume, under the conditions set out in Section 1 (7).
2. Where, at a particular demand point in the transmission system or distribution system, there are time changes in the gross calorific value, the gross calorific value charged shall be determined as the weighted average of the gross calorific value supplied for the accounting period.
3. Where gas is supplied to customers from a single transfer point with a fluctuating energy value, the time averages of the gases by volume, the gas volumes supplied and the product of the volumes and the gases by volume (the amount of gas supplied) shall be determined. The weighted average of the gross calorific value for the entire accounting period is the sum of the amounts and gross calorific values of the gas delivered over the same period.
4. Where several sources of gas are supplied to the area which differ in volume by their gross calorific value, the weighted average of the gross calorific value of the gross calorific value for the accounting period shall be determined by the proportion of the sum of the energy delivered for the accounting period from each source and the sum of the total volumes of the gas delivered per year from those sources.
5. In exceptional cases where there are fluctuations in the gross calorific values (repairs, accidents, exceptional measures by technological operations of short-term nature, major random errors in the measuring equipment), for a limited period of up to 10 days within 12 months, these values of the gross calorific values shall not be taken into account in the calculation of the annual gross calorific values charged.
6. In the case of a volume-based gross calorific value in relation to the weighted monthly averages over the previous 12 months, not more than ± 4% shall be used to determine the average gross calorific value of the individual measuring points included in the separate supply system.
7. In the event that this derogation is greater than ± 4% for reasons other than those referred to in point 5, the operator concerned shall establish additional gas composition measuring points demonstrating compliance with the stable combustion heat in the tolerance referred to in point 6.
8. The detailed procedure for converting the volume units delivered and collected into energy is set out in the technical rules.

Method of determining the gas consumption for final customers, where it could not be detected either by subtracting the measuring equipment or by sending the completed data on a separate form of the operator of the relevant system
In order to determine the size of the gas collection for final customers, where it was not possible to detect it either by subtracting the measuring equipment or by sending the completed data on a special form of the operator of the relevant system or other in the gas supply contract in an agreed manner, the following percentage distribution of monthly withdrawals shall be used with the application of a proportion of less than a month.
(a) final customers with consumption above 720 m3 / year using gas for heating or heating in combination with hot water heating and stove
| měsíc | 01 | 02 | 03 | 04 | 05 | 06 | 07 | 08 | 09 | 10 | 11 | 12 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| % | 16,72 | 14,29 | 11,02 | 7,94 | 3,84 | 1,83 | 1,62 | 1,62 | 5,86 | 6,83 | 10,50 | 17,93 |
(b) final customers with a consumption not exceeding 720 m3 / year by evenly dividing the gas supply during the year;
(c) for the determination of non-measured gas sampling to end customers with a technological sampling, a uniform distribution of gas supply shall be used during the reading period.
