The prices are collected in national currencies per GJ and according to different bands of consumption. For the households sector, these bands are:
For the final non-households sector, the bands are:
There exist 2 different levels of disagregation for semestrial and annual prices: 1- Semestrial prices: These prices are reported twice a year and are divided in 3 levels:
2- Annual prices: These prices are reported once a year together with the data for the second semester and are divided into the following components and taxes:
In addition to these elements, the network cost is split into the respective shares of transmission and distribution. The relative share of consumption in the different consumption bands is reported by the countries and used to calculated the single national natural gas prices (weighted averages for consumer bands IA-IF and DA-DE) but not published because it could be used to re-calculate some confidential values. VAT: 21,0 % Excise tax: natural gas only for final non-household customers: 30.60 CZK/MWh VAT for non-household customers is the only tax that is recoverable.
Other taxes: a fee for the activities of the market operator and Energy regulatory ofice in total in CZK / MWh. Fee is same and valid for all final consumers (households and non-households). Prices compensation on electricity and natural gas in the year 2021

Households gas prices collection: 2.06185E-05 Non-households gas prices collection: 0 |
|
|||
18.1. Source data | |||
Natural gas non-households: Data are obtained through a quarterly survey "Ceny E6-04". Regulated prices are from Energy Regulatory Office. Regulated prices are valid for the whole year. Natural gas households: Data are obtained from the price lists of retailers. Since 2023 new methodology is introduced, for more information see point 18.5. |
|||
18.2. Frequency of data collection | |||
Natural gas non-households: prices - quarterly, consumption and number of consumers - yearly. Natural gas households: prices - quarterly and when the price change, consumption and number of consumers - yearly. |
|||
18.3. Data collection | |||
Data collection media: Electronic questionnaires, E-mails, web questionnaires, PDF questionnaires. Planned changes in data collection methodology: New web questionnaires. |
|||
18.4. Data validation | |||
Data are controlled individually. Verification of prices: Specialists analyze the reported price changes and the reasons for price change as indicated (in code including commentary) by the reporting units. They remain in close contact with the reporting units. Verification of processing: Price changes are, among other things, compared with the previous period and comments provided by reporting units. The influence of price changes in individual products and groups on the development of the total is analyzed, as well as the influence of item substitution. Checks are made on the weights and the correctness of the calculations. Once a year, the weighting structure is compared with the most recent data on annual sales. |
|||
18.5. Data compilation | |||
Natural gas non-households: Prices of natural gas are surveyed by the national statistical questionnaire ‘Ceny E 6-04’ (‘Prices E 6-04’).Reporting units report average prices according to the consumption bands wit planned total consumption and number of supply points. Average prices of natural gas for consumption bands total are calculated as a weighted arithmetic average of prices recorded by the most important traders with natural gas and the weights are market shares in the individual bands. Reported prices are prices agreed between trader and his final domestic consumer. Quarterly average prices natural gas for industry total are also published. For the Czech Republic, these prices are provided to International Energy Agency (IEA). Average quarterly prices are calculated as a weighted arithmetic average from average prices of individual consumption bands and their share on the yearly consumption.
Natural gas households: Prices of natural gas are obtained from the price lists published by natural gas traders. Prices of commodity and prices of natural gas total (including: commodity, transmission, system and distribution) are gained. Typical consumption plans for final consumers in all consumption bands are published every year by Energy regulatory office. Average prices of naturla gas for individual consumption bands are calculated as a weighted average from the prices of above mentioned typical final consumers coverng whole required spectrum of consumption. Once per year reporting units report a yearly consumption for every consumption band.
The method of calculating prices for households and small consumers introduced from 2023 In 2023, an extraordinary price investigation took place. The calculation is carried out by the CZSO The 7 main gas and electricity retailers for households. Collected data on sales (CZK) and sales in physical units (MWh). Division of the collected data into standardized sampling bands determined by Eurostat (the documents are supplied by the respondents). The resulting unit price for the given band is the share of sales (CZK) and physical units (MWh). There is a separate calculation of the total price and the price for only the power part (commodity). Determining the prices actually paid (average for a given consumption band). From 2024, it will be included among the standard statistical surveys, it will be part of the monthly report on electricity prices (Ceny Elek 1-12) and on natural gas prices (Ceny E6-04). The data in the new methodology describe realized energy prices for households. The data in the original methodology describe the offered energy prices for households. |
