(11) the amount of compensation for an unauthorized gas may also be
a written agreement between the transmission system operator or
distribution system operator and a customer, or a person
should illegal gas sampling on a benefit or advantage
participated. The compensation provided for in this way must not be higher than
the refund calculated in accordance with the preceding paragraphs.
(12) for the determination of the amount of damages in wrongful supply of gas,
When the unauthorized transport of gas, or when unauthorized distribution of gas

Annex 1
The conversion of the volumes of gas to energy
(1) the basis for the accounting of gas supply to the gas market participants is
the amount of energy supplied in the gas.
(2) the amount of energy Supplied gas is determined by the relation
Q = Vp. to the. It
Where is:
Q-quantity of energy in kWh supplied
VP-operational volume of gas in m3 measured meter operating pressure and temperature
for the billing period to the nearest whole unit
k-volume rating factor is the ratio between the volume of a gas at reference
conditions and the volume of production, rounded to four decimal places.
It-the average value of the gross calorific value kWh/m3 in volume for posting
period, rounded to four decimal places.
(3) the volumetric rating factor for dry gas is calculated from the relation
Tv pp + pb zoom
k = ------ x ----------- x ------
TP zp pv
where is:
Tv-reference temperature expressed in a scale of Kelvinově to 288.15 (tv = 15 ° c),
where tv is the reference temperature in ° c
TP-temperature gas at the meter, expressed in the Kelvinově scale, rounded
to two decimal places
pp-working pressure of gas expressed in kPa measured in meter or
set value output overpressure gas pressure regulator
located in front of the meter or by or for the average value rounded
to one decimal place
PB-the average annual value of the atmospheric pressure of the air in the place of sampling gas
in kPa; rounded to one decimal place; for the determination of this value
It is the responsibility of the transmission system operator or distribution system operator,
from which the gas is supplied to the
PV-the reference pressure 101.325 kPa, in the amount of
ZV-kompresibilní factor in the reference conditions
ZP-kompresibilní factor in operating conditions
(4) If, at the point of use to time changes the values of the gross calorific value
by volume, its average value as the mean value of the
supplied in terms of volume for the billing period. Medium
the value supplied in terms of volume is determined by the weighted
average. If the billing period is longer than 1 month, the
the mean gross calorific value of volume for the billing period, the weighted
the average of the previous 12 months.
(5) if the area of the gas supplied to the gas from one point to
fluctuating energy value, the time averages of the spalných
ther vol. delivered volumes of gas and products of the heat volumes and spalných
by volume (the amount of energy supplied to gas). The weighted average gross
heat a solid for the whole billing period is the sum of the products of time
volumes and spalných heat divided by the total volume delivered volume
gas per billing period.
(6) in the event that in the field of gas is supplied to the gas from different
sources that differ spalnými teply volumes, is the weighted average of the
in terms of volume for the period determined by the proportion of the sum of the
the amount of energy supplied for the posting period from these sources, and the sum of the
the total volumes of gas supplied from these sources.
