Dear Gas Customers,
In accordance with the provision of the General Conditions for Natural Gas Supply, determining and billing gas quantities as well as expressing unit prices for gas as a unit measure will use kWh.
Since 2014, changes to legal regulations has led to changes in billing consumption of natural gas:
- The billed metering places are categorised into tariff models (TM1 to TM12), depending on natural gas consumption in the previous year, and
- billed metering places are assigned a correction factor, a coefficient used to multiply the value of gas volume measured at the gas meter during working conditions for metering in order to obtain the value of gas volume which conforms to the standard state of gas
Data on tariff models and correction factors, we as the supplier receive from distribution system operators in accordance with the Network Rules for the Gas Distribution System (OG 50/18).
Gas consumption by customers in the household category are subject to prescribed gas prices:
- from 01/08/2018 to 31/03/2019, the Decision on the Amount of Tariff Items for the Public Gas Supply Service for the Period from 1 August to 31 December 2018 and for the Period from 1 January to 31 March 2019 (OG 60/2018 and 61/2018)
