3.1. Data description

Annual data on crude oil, oil products, natural gas, electricity, solid fuels and renewable covering the full spectrum of the energy balances positions from supply through transformation to final energy consumption by sector and fuel type.

Monthly data on crude oil, oil products, natural gas, electricity and solid fuels, covering mainly the supply side.

Also, annual and monthly imports and exports data of various energy carriers by country of origin and destination, as well as infrastructure information.

All the above is measured in physical units (t, TJ, kWh, toe, etc.).

In general, annual data collections cover the full spectrum of the 27 Member States of the European Union, the European Economic Area countries Iceland and Norway, and the Candidate Countries FYROM, Croatia and Turkey, with time-series reaching back to 1990 (for some new Member States selected energy indicators belonging to the major collections "Structural Indicators" and "Euro indicators" are included).

3.2. Classification system

Energy statistics is an integral part of the European system of statistics. Therefore, they rely heavily on classifications and nomenclatures developed in other fields while classifications proper to the Energy statistics are fully harmonised with the classifications used in other fields of the European system of statistics. The classification of the economic activities both in carrying out the surveys and in presenting the results (Energy Balance Sheets) is in accordance to NACE Rev.2 (see RAMON, Eurostat's classification server available on this website).

3.3. Coverage - sector

Not available.

3.4. Statistical concepts and definitions

The measurement of energy quantities produced, traded (incl. by country of origin/destination), transformed and consumed as well as structural characteristics of energy production/transformation installations.

3.5. Statistical unit

Energy quantities are at national level.

3.6. Statistical population

Not available.

3.7. Reference area

Annual and monthly data series cover EU Member States and Candidate Countries (except Croatia), Norway and Iceland (only annual data for Iceland are collected). The EU-25, EU-15, Euro-zone and Accession and Candidate countries (until 1.5.2004) totals are also shown.

3.8. Coverage - Time

From 1990 onwards.

3.9. Base period
Not Applicable

4. Unit of measureTop

Basic data are on energy quantities are in fuel specific units e.g. liquid fuels in thousand tonnes, electricity in kilowatt-hours, while structural data on the capacity of installations are in Megawatt, thousand tonnes per year (production capacity) or thousand square meters of installed surface in case of solar panels. The basic energy quantities data are converted to energy units, i.e. in Terajoules and Tonnes of oil equivalent to allow the addition of different nature fuel types.

5. Reference PeriodTop

Annual statistics refer to the calendar year. Monthly data cover a calendar month.

6. Institutional MandateTop
6.1. Institutional Mandate - legal acts and other agreements

Energy indicators are compiled on the basis of the data collected under the standard collection cycles of the "Energy Statistics Unit". The relevant energy data collections are regulated since 2008 with the entry-into-force of the Regulation (EC) No 1099/2008 of the European Parliament and of the Council of 22 October 2008 on Energy Statistics.

Standardised questionnaires are used:

  • Five annual questionnaires (Joint Eurostat/IEA/UNECE questionnaires) that contain detailed explanatory notes on the accounting conventions to be used for each fuel. These conventions are agreed and reviewed regularly by the three organisations using these questionnaires.
  • Six monthly questionnaires (four Eurostat questionnaires and two questionnaires common with other international organisations). Monthly data are collected with the monthly oil questionnaire of the International Energy Agency, a copy of which is sent to Eurostat and the Solid fuels and Electricity Eurostat (only) monthly questionnaires. Fuel conventions for reporting monthly statistics can also be found in attached to these questionnaires.
6.2. Institutional Mandate - data sharing

Not available.

7. ConfidentialityTop
7.1. Confidentiality - policy

Regulation (EC) No 223/2009 on European statistics (recital 24 and Article 20(4)) of 11 March 2009 (OJ L 87, p. 164), stipulates the need to establish common principles and guidelines ensuring the confidentiality of data used for the production of European statistics and the access to those confidential data with due account for technical developments and the requirements of users in a democratic society.

7.2. Confidentiality - data treatment

See below.

8. Release policyTop
8.1. Release calendar

The precise date of data release is disseminated on Eurostat's website (select language and release calendar).

8.2. Release calendar access

No particular provisions.

8.3. Release policy - user access

In line with the Community legal framework and the European Statistics Code of Practice Eurostat disseminates European statistics on Eurostat's website (see item 10 - 'Dissemination format') respecting professional independence and in an objective, professional and transparent manner in which all users are treated equitably. The detailed arrangements are governed by the Eurostat protocol on impartial access to Eurostat data for users.

DG ENER has got a pre-release access to the production database for verification purposes. It is to be noted that DG ENER

  • is not allowed to publish any data before Eurostat has disseminated them and
  • has been informed to be cautious with the data when the validation has not yet been completed.

9. Frequency of disseminationTop

Data are disseminated on annual and monthly basis .

10. Dissemination formatTop
10.1. Dissemination format - News release

News releases on-line.

10.2. Dissemination format - Publications

The following publications are created from annual energy data:

  • Pocketbook: Energy, transport and environment (paper and pdf)
  • Energy balance sheets (pdf)
  • Several SiF's
  • Several Statistics Explained articles
  • A few Press Releases

For more information see Section 7.4.

10.3. Dissemination format - online database


The annual energy data on quantities is published in Eurobase under Environment and Energy > Energy > Energy statistics - quantities, annual data

The contents and dimensions of each table are described in document under

O:\Energy\Final files for SIRENE migration\Dissemination tables.doc

10.4. Dissemination format - microdata access

Not applicable

10.5. Dissemination format - other

There is a dedicated section in Eurobase for energy statistics

where methodological guidelines, publications etc. are available.

11. Accessibility of documentationTop
11.1. Documentation on methodology

Detailed information on the relevant methodology as well as documentation links can be found in the 'Energy quantities methodology sheet' found in the Summary Methodology Sheets (see Annex at the bottom of the page).

11.2. Quality management - documentation

Not available.

12. Quality managementTop
12.1. Quality assurance


12.2. Quality management - assessment

It should be noted that in presenting energy statistics important deviations appear which may pose problems, when the energy statistics are compared with related ones coming from the national accounts. The relevant deviations are listed below:

  • Electricity generation from autoproducers is presented separately from the sector where it takes place,
  • Energy consumption for transport is also separated from the actual sector where it takes place,
  • The energy industry both as a consumer and as a transformer of energy has been separated from the rest of the industry.

13. RelevanceTop
13.1. Relevance - User Needs

Annual and monthly energy quantities statistics are collected and published by Eurostat in order to:

  • Provide the Commission with harmonised, reliable and relevant statistical information needed to define, implement, monitor and evaluate Commission policies in the energy sector.
  • Provide the EU institutions, national administrations, enterprises, professional associations and EU citizens with high quality statistical services and products in the field of energy.
13.2. Relevance - User Satisfaction

Not available.

13.3. Completeness

Not available.

14. AccuracyTop
14.1. Accuracy - overall

Data on energy is submitted on the basis of an Annual Joint Questionnaire employing an internationally agreed methodology.  Eurostat receives disaggregated data which are used to countercheck the results and to ensure consistency with the total amount of energy consumption. The accuracy of the basic data depends on the quality of the national statistical systems and may vary from country to country.  In several countries and for most energy commodities data provision by the companies is required by law. However, emerging liberalisation process in some countries may to some extent negatively affect accuracy in some cases.  From time to time detailed surveys targeted to single sub- items (e.g. Wood consumption in households) are carried out to improve the methodology.

14.2. Sampling error

Not available.

14.3. Non-sampling error

Not available.

15. Timeliness and punctualityTop
15.1. Timeliness

As per the relevant Energy Statistics Regution 1099/2008.

Monthly data provided three months after the reference month (M+3) and annual data provided 11 months after the reference year.

15.2. Punctuality

Not available.

16. ComparabilityTop
16.1. Comparability - geographical

Fully comparable data due to the use of the joint questionnaire. Eurostat verifies to the extent possible if the reported data respect the prescribed methodology. The underlying data collection methods are however the responsibility of the Member States. The methodology is harmonised for all EU and OECD countries, including the USA and Japan. 

16.2. Comparability - over time

Comparability over time is ensured with a constant methodology (unless new data would be included).

17. CoherenceTop
17.1. Coherence - cross domain

Dissemination is maintained on Eurostat's database on both an annual and a monthly basis for the energy quantity statistics. Very detailed analysis of energy balances at national level provides assurance of consistency of many of the quantitative data included in this dissemination.

17.2. Coherence - internal

Data are checked in detail for internal consistency/coherence in full cooperation with the Member States concerned.

18. Cost and BurdenTop

Not available.

19. Data revisionTop
19.1. Data revision - policy

The annual questionnaires provide data on the last reference year and revisions for the year before. Revisions of entire time series are often made by Member States due to specific survey or data revision/harmonisation projects. These revisions are then reflected in the annual questionnaires and are also implemented by Eurostat in due time.

Monthly data transmitted to Eurostat often contain provisional information, which is revised in as soon as the definitive information is made available usually the following month or at the end of the quarter or year depending on the Member States short term collection system.

19.2. Data revision - practice

Data are occasionally updated in case an error would be identified, if a Member State transmits more uptodate figures or if provisional data are modified into definitive ones.

20. Statistical processingTop
20.1. Source data

Not applicable

20.2. Frequency of data collection

Both annual and monthly statistics are collected. The monthly statistics are much more limited and do not cover consumption details but they are of course available much sooner and therefore interesting for early trend analysis.

20.3. Data collection

Data cycle starts in July for the previous year's data and ends in the following February - March. See below for details.

20.4. Data validation

See below

20.5. Data compilation

See below.

20.6. Adjustment

No adjustments of data are performed in a systematic way.
