3.1. Data description | |||
Physical energy flow accounts (PEFA) is one module of the European environmental-economic accounts - Regulation (EU) 691/2011 Annex VI. PEFA record the flows of energy (in terajoules) from the environment to the economy (natural inputs), within the economy (products), and from the economy back to the environment (residuals), using the accounting framework of physical supply and use tables. PEFA provide information on energy flows arranged in a way fully compatible with concepts, principles, and classifications of national accounts – thus enabling integrated analyses of environmental, energy and economic issues e.g. through environmental-economic modelling. PEFA complement the traditional energy statistics, balances and derived indicators which are the main reference data source for EU energy policies.
The PEFA questionnaire is available on Eurostat's website: https://ec.europa.eu/eurostat/web/environment/methodology |
|||
3.2. Classification system | |||
Physical energy flow accounts (PEFA) datasets have the following dimensions:
|
|||
3.3. Coverage - sector | |||
The data set covers the entire national economy as defined in national accounts (ESA 2010, paragraph 2.04), as well as its physical relation to economies in the rest of the world and the environment.
|
|||
3.4. Statistical concepts and definitions | |||
Physical energy flow accounts (PEFA) are conceptually rooted in the System of Environmental-Economic Accounting (SEEA) which is an international statistical standard. The SEEA central framework provides standard concepts, definitions, classifications, accounting rules and tables for the provision of statistics on the environment and its relationship with the economy. |
|||
3.5. Statistical unit | |||
Data refer to activities of resident economic units in the sense of SEEA CF 2012 and national accounts (ESA), including households. |
|||
3.6. Statistical population | |||
The national economy is as defined in SEEA CF 2012 and national accounts (ESA); i.e. all economic activities undertaken by resident units (see ESA 2010, paragraph 2.04). A unit is said to be a resident unit of a country when it has a centre of economic interest in the economic territory of that country, that is, when it engages for an extended period (1 year or more) in economic activities in that territory. |

15.3.2. Coherence - National Accounts | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
ESA use tables we used as one of the auxiliary data source to obtain NACE A*64 and households distribution key for Table B (in case that data from the Energy companies database were not available for some energy fuels or products). ESA data was not available for 2021, so 2020 data was used. Department of National Accounts of CZSO next year is going to plan to publish a major revision of the National Accounts, detailed supply and use tables will be compiled only for this publication, consistent with the revised National Accounts time series. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
15.3.3. Do you cooperate with national colleagues compiling AEA? | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
We started to work on consistency with AEA during data collection 2017, during the data collection 2023 we continued the work on this consistency. Mainly it is focused on data on fuel consumption by residents abroad and non-residents in our country. Common data sources for residents abroad and non-residents in our territory were used from different areas of statistics (foreign trade statistics, tourism and transport statistics, NA data). For residents in our territory we used common sources from energy statistics (Annual Oil Questionnaire, Energy survey EP 5-01, ENERGO survey - households). |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
15.3.4. Are there compilation elements that PEFA compilers jointly undertake with AEA compilers (e.g. distribution of road transport fuel use and emissions by NACE)? | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Common data sources for residents abroad and non-residents in our territory were used from different areas of statistics (foreign trade statistics, tourism and transport statistics, NA data). For residents in our territory we used common sources from energy statistics (Annual Oil Questionnaire, Energy survey EP 5-01, ENERGO survey - households). |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
15.3.5. Do you report in PEFA imports and exports according to the SEEA-CF concepts for trade in goods (see SEEA-CF section 3.3.3, paras. 3.121 ff., and para. 1.46)? | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

18.1. Source data | |||
Data sources used to produce physical energy flow accounts are described in the following sub-concepts. |
|||
18.1.1. Which are the main data sources you employ for the use of natural energy inputs (i.e. who is extracting)? | |||
The primary data source for natural energy inputs was five IEA/Eurostat Annual Energy Statistics Questionnaires. These questionnaires were imported and processed in the PEFA Builder.
|
|||
18.1.2. Which are the main data sources you employ for supply of energy products (e.g. electricity, refinery products etc.)? | |||
TABLE A,B,B.1,B.2,E: The primary data source for residents in the CZ was five IEA/Eurostat Annual Energy Statistics Questionnaires. These questionnaires were imported and processed in the PEFA Builder. The data source for resident enterprises abroad was the Foreign trade Statistics, survey ZO 1-04 (Quarterly questionnaire on imports and exports of services) and the database on air transport CO2 emissions published by OECD. |
|||
18.1.3. Which are the main data sources you employ for the transformation use by energy transforming entities (NACE 2-digit divisions)? | |||
TABLE A,B,B.1,B.2,E: The primary data source for residents in the CZ was five IEA/Eurostat Annual Energy Statistics Questionnaires. These questionnaires were imported and processed in the PEFA Builder. The data source for resident enterprises abroad was the Foreign trade Statistics, survey ZO 1-04 (Quarterly questionnaire on imports and exports of services) and the database on air transport CO2 emissions published by OECD. |
|||
18.1.4. Which are the main data sources you employ for the end use by end user entities (including non-energy use)? | |||
TABLE A,B,B.1,B.2,E: The primary data source for residents in the CZ was five IEA/Eurostat Annual Energy Statistics Questionnaires. These questionnaires were imported and processed in the PEFA Builder. The data source for resident enterprises abroad was the Foreign trade Statistics, survey ZO 1-04 (Quarterly questionnaire on imports and exports of services) and the database on air transport CO2 emissions published by OECD. |
|||
18.1.5. Which auxiliary data do you use to develop 'distribution keys' to assign energy use to the detailed breakdown of production activities (NACE 2-digit divisions) and categories of household consumption? | |||
The auxiliary data source was data from the Energy companies database (data in TJ) managed by the Energy Statistics Unit (CZSO) in cooperation with the Ministry of Industry and Trade.In cases where data from the Energy companies database were not available for some energy fuels or products, then another auxiliary data source was used - the annual Monetary use table (with a three digit level),data in monetary units (CZK) were filled into the file PEFA NaceBreakdown (distribution key). |
|||
18.1.6. Do you use the PEFA builder? If yes: for populating the PEFA Tables, or for control only? | |||
Yes, for populating the PEFA Tables. |
|||
18.1.7. Which data sources do you use to make adjustments for the residence principle? | |||
Adjustments to the residence principle were made only for air and road transport. International air transport – purchases by non-residents on the territory Road transport fuel use – resident enterprises abroad
|
|||
18.2. Frequency of data collection | |||
The source data are collected annually. |
|||
18.3. Data collection | |||
Not applicable. |
|||
18.4. Data validation | |||

|||
18.5. Data compilation | |||
|
|||
18.5.1. Imputation - rate | |||
Not applicable. |
|||
18.5.2. Do you assign all supply of electricity and heat to NACE D35, or do you assign some to other NACE divisions than D35? Is the assignment you did fully aligned to the ESA monetary supply table submitted by your country? | |||
Data 2019 -2021: Some electricity and heat supply was assigned to other NACE divisions than D35. Data 2019 -2021 was obtained from the Energy companies database managed by the Energy Statistics Unit (CZSO) in cooperation with the Ministry of Industry. |
|||
18.5.3. Which method do you use for the allocation of road transport energy use to NACE industries and households? | |||
The primary data source was IEA/Eurostat Annual Oil Energy Questionnaire.The Annual Oil Energy Questionnaire was imported and processed in the PEFA Builder. Only total transport fuel use data in TJ for individual fuels were obtained.Total road transport fuel use data therefore had to be re-allocated into NACE A*64 by the auxiliary data source.The NACE aggregation level A*64 is not publicly available for road transport fuel use in energy statistics, but expert estimates were made in the Energy Statistics Unit (CZSO) for the purpose of PEFA .The estimated data are based on results of the survey EP 5-01. |
|||
18.5.4. Which method do you use for the allocation of energy use to detailed service industries (i.e. NACE 2-digit divisions 55-98)? | |||
Expert estimates were made in the Energy Statistics Unit (CZSO) for the purpose of PEFA .The estimated data are based on results of the survey EP 5-01. |
|||
18.5.5. How do you ensure a coherent assignment of energy use to economic activities (i.e. the use of energy products by a given production activity (NACE A*64 division) reported in PEFA must be coherent with the emissions reported in AEA)? | |||
For the next data collection in 2024, as part of the cooperation on data coherence, the AEA compilers were provided with the same data 2021 in the NACE A*64 breakdown as used by PEFA. The AEA compiler will analyze the data against its data source and resolve inconsistencies. |
