3.1. Data description | |||
European statistics on natural gas prices for household and final non-household customers. |
|||
3.2. Classification system | |||
Internal Eurostat classification system based on annual natural gas consumption bands and tax levels. |
|||
3.3. Coverage - sector | |||
Household sector and final non-household sector (industry, services, offices, agriculture, etc). |
|||
3.4. Statistical concepts and definitions | |||
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. Value added tax is refundable for non-households cosnumers. It is reported in Level 3 prices.
|
|||
3.5. Statistical unit | |||

Prices are reported in national currency per GJ. However, Eurostat also calculates and publishes the prices in EURO and PPS (purchasing power parity) and do the conversion to kWh. |
|
|||
For semestrial prices, the reference periods are from January to June for semester 1 and from July to December for semester 2. For annual prices, the reference period is the whole calendar year (from January to December). |

It has been distinguished between two levels of checking: 1/ Formal checks, which are realised in the process of data entry automatically; 2/ Informal checks aim of which is to control the complexity and relations among the variables . According to the importance there are classified 2 basic types of informal checks: I – informative check- this check gives the additional information, which is important for the following process of corrections. It informs also about some inconsistencies in the state of fulfilment of the questionnaire, about item non-response, exceeding stated limits etc. Z – check of great importance - it is mostly check indicating the exact error and it must be always corrected or explained. Most of the errors are directly consulted with the reporting units by our regional offices. |
