XI. Natural Gas Accounting for the Settlement of Payments for Natural Gas

119. The quantity of the natural gas consumed by the system user shall be recorded in cubic metres (hereinafter - m3). If commercial meters have been equipped with temperature and pressure conversion devices, accounting data shall be determined under standard circumstances.

120. For the purposes of the system user's settlement of payments with the natural gas trader for the consumed natural gas, as well as the received distribution system services, the distribution system operator shall re-calculate the recorded quantity of natural gas as kWh by using the data published on the website of the transmission system operator regarding the average weighted gross calorific value of natural gas under standard circumstances per gas day.

121. The transmission system operator shall ensure that the distribution system operator has access to provisional online data of commercial meters which record the quantity of natural gas supplied to the distribution system and determine parameters of natural gas in order to enable the identification of volume and content of natural gas supplied to each calorific value area of natural gas on a daily basis. The procedures for accessing data and the division of the transmission system in areas shall be determined by the distribution system operator and the transmission system operator in the mutually entered into contract. The distribution system operator shall publish the division of the transmission system in calorific value areas of natural gas on its website.

122. The distribution system operator shall develop the procedures for determining the number of calorific value areas of the distribution system and the gasified objects belonging to each area, and publish this information on its website.

123. Calorific value of the natural gas which has flown into the distribution system shall be determined by using the following formula:

 

H1 × V1 + H2 × V2 +…+ Hn × Vn

, where

V1 + V2 +…+ Vn

H - the average daily weighted calorific value of the gas in the distribution system;

H1, H2, .. Hn - the average daily weighted gross calorific value of the natural gas which has flown into the system through the first, second, .. n entry point of the distribution system;

V1, V2, .. Vn - volume of the natural gas which has flown into the system through the first, second, .. n entry point of the distribution system in the relevant day and measured at the relevant exit point of the transmission system and point of connection of the distribution system.

The average calorific value of natural gas in the calorific value area of the distribution system per gas day shall be calculated by determining the average daily weighted calorific value of the natural gas which has flown into the calorific value area through all entry points.

124. The natural gas consumed by the system user in m3 shall be re-calculated by the distribution system operator as kWh by using the following formula:

E = V x Hs , where

E - the natural gas supplied in the period for the settlement of payments, kWh;

V - the natural gas supplied in the period for the settlement of payments, m3;

Hs - the average weighted gross calorific value of natural gas under standard circumstances in the period for the settlement of payments (kWh/m3) for the relevant calorific value area.

125. The distribution system operator shall determine the natural gas consumed in the period for the settlement of payments in gasified objects with a place for non-daily accounting as kWh by multiplying the quantity of natural gas recorded in the period as m3 by the average monthly weighted gross calorific value of gas in the calorific value area.

126. The natural gas supplied in the period for the settlement of payments in gasified objects with a place for daily accounting as kWh shall be determined by multiplying the actual quantity of natural gas measured in each day as m3 by the average weighted gross calorific value per gas day in the calorific value area of the distribution system and aggregating quantity of energy per gas day in the calorific value area of the distribution per each gas day. If it has been impossible to determine the actual measured quantity of natural gas per gas day in gasified objects with a place for daily accounting, the quantity of natural gas read by commercial meters as m3 shall be determined by multiplying the average monthly weighted gross calorific value of gas in the calorific value area for the days when the quantity of the consumed natural gas was not measured in the period for the settlement of payments.

127. For the purposes of forecasting, the quantity of natural gas distributed in the distribution system per day shall be calculated by aggregating the following data:

127.1. the consumption received or submitted by the system users from places for daily accounting;

127.2. the consumption calculated by the distribution system operator or submitted by the non-household consumer regarding the quantity of natural gas consumed per gas day in places for non-daily accounting;

127.3. the quantity of the natural gas distributed to household consumers per day in places for non-daily accounting and calculated by the distribution system operator.

128.
