European statistics on natural gas prices for household and final non-household customers.

Internal Eurostat classification system based on annual natural gas consumption bands and tax levels.

Household sector and final non-household sector (industry, services, offices, agriculture, etc).

The prices are collected in national currencies per GJ and according to different bands of consumption.

For the households sector, these bands are:

• D1: Customers consuming less than 20 GJ.
• D2: Customers consuming 20 GJ or more but less than 200 GJ.
• D3: Customers consuming 200 GJ or more.

For the final non-households sector, the bands are:

• I1: Customers consuming less than 1000 GJ.
• I2: Customers consuming 1000 GJ or more but less than 10000 GJ.
• I3: Customers consuming 10000 GJ or more but less than 100000 GJ.
• I4: Customers consuming 100000 GJ or more but less than 1000000 GJ.
• I5: Customers consuming 1000000 GJ or more but less than 4000000 GJ.
• I6: Customers consuming 4000000 GJ or more.

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:

• Level 1 prices: Prices excluding taxes and levies.
• Level 2 prices: Prices excluding VAT and other recoverable taxes and levies.
• Level 3 prices: Prices including all taxes and levies.

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:

• Energy and supply: commodity price for natural gas paid by the supplier or the price of natural gas at the point of entry into the transmission system, including, if applicable, the following end-user costs: storage costs plus costs relating to the sale of natural gas to final customers.
• Network cost: transmission and distribution tariffs, transmission and distribution losses, network costs, after-sale service costs, system service costs and meter rental and metering costs.
• Value added taxes (VAT): as defined in Council Directive 2006/112/EC.
• Renewable taxes: taxes, fees, levies or charges relating to the promotion of renewable energy sources, energy efficiency and CHP generation.
• Capacity taxes: taxes, fees, levies or charges relating to strategic stockpiles, capacity payments and energy security; taxes on natural gas distribution; stranded costs and levies on financing energy regulatory authorities or market and system operators.
• Environmental taxes: taxes, fees, levies or charges relating to air quality and for other environmental purposes; taxes on emissions of CO₂ or other greenhouse gases.
• All other taxes: taxes, fees, levies or charges not covered by any of the previous four categories: support for district heating; local or regional fiscal charges; island compensation; concession fees relating to licences and fees for the occupation of land and public or private property by networks or other devices. This component includes the excise duties.

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 I1-I6 and D1-D3) but not published because it could be used to re-calculate some confidential values.VAT is refundable for non-household sector.

In the table below are the taxes reported in "All other taxes"

Revisions were made because some suppliers resubmitted more accurate data or for the correction of the flag of the data

The legal deadline for submitting the questionnaires is the third month after the reference period. The main reason for delays in submitting questionnaires is the late response of data providers.

See above answer in 14.2.

Collected data concern the whole territory, therefore there is no comparison between different geographical areas.

Not applicable.

Gas prices are comparable over time.

There is no break in time series.

Not applicable.

Not applicable.

Not applicable.

Annual prices are coherent with the semestrial prices.

Total cost and burden are not possible to be calculated.

Whenever data is submitted as provisional, a revision follows as soon as the final data is available. In case one or more data providers submit a revision, prices are recalculated and submitted as soon as it is possible and no longer than a month after the change occurs. If the revision refers to more than 2 semesters backwards, a preannouncement takes place. When necessary, the semester 1 data is revised when submitting the semester 2 data for consistency reason between semestrial and annual prices.

Revision practice is described in S.17.1.

See point 14.1.2.

Revisions take place when providers submit data either after deadline or revised.

Households gas prices collection: 0.022841838

Non-households gas prices collection: 0.017579998

The data comes from companies that supply / sell natural gas to final households or non-household consumers.

For gas prices: half yearly

For gas price components: yearly

Ministry sends Eurostat΄s questionnaires to all data providers that cover gas prices for both household & non household sectors.

This micro data is aggregated to national consumption-weighted average price per consumption band. Gathered data cover a representative share of the gas market.

Submitted data is validated for consistency and completeness, by comparing the values with previous cycles and by checking that the population coverage and response rates are as required.

In case of inconsistent price data, the data providers are contacted to request a reconfirmation of the data.

Data represent weighted average prices, using the market shares of gas supply companies in calculations.

Imputation rate is considered to be negligible.

Not applicable.

Seasonable adjustments are not carried out.

Gas prices data are collected and handled by the Department for Organization and Supervision of Natural Gas Market of Directorate for Hydrocarbons.
