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.

This national metadata refers to the PEFA questionnaire delivered to Eurostat: data on supply (table A), use (table B), transformation use (table B1), end use (table B2) and emission-relevant use (table C), key indicators of physical energy flow accounts by NACE Rev. 2 activity (table D), and physical energy flow accounts totals bridging to energy balances totals (table E).

The PEFA questionnaire is available on Eurostat's website: https://ec.europa.eu/eurostat/web/environment/methodology

Physical energy flow accounts (PEFA) datasets have the following dimensions:

1. Supply and use tables (STK_FLOW): the elements of this dimension are the five tables detailing energy supply (questionnaire table A) and use; the total energy use (table B) is the sum of transformation use (table B1) and end use (table B2), and a certain part of it is emission relevant (table C).
2. Energy product (PROD_NRG): (not relevant for questionnaire table D and E) The flows of energy recorded in PEFA are broadly grouped into natural energy inputs (flows from environment to economy), energy products (flows within economy), and energy residuals (flows from economy to environment mainly). Each of these generic groups is further broken down. In total this dimension distinguishes 31 items which are regulated in Commission Delegated Regulation (EU) 2016/172.
3. Classification of economic activities - NACE Rev.2 (NACE_R2): (not relevant for questionnaire table E) The supply and use of energy flows is broken down by NACE classification of economic activities. The aggregation level used is A*64 (i.e. 64 branches), fully compatible with ESA supply and use tables. Furthermore, this dimension includes private households, accumulation (e.g. product inventories), the rest of the world economy for imports and exports, and the environment.
4. Indicators (INDIC_PEFA): (only relevant for questionnaire tables D and E): Various key indicators that can be derived from the physical supply and use tables and so-called 'bridging-items' which present the various elements explaining the differences between the national totals as reported by PEFA vis-a-vis the national totals as reported by Eurostat's energy balances.
5. Geopolitical entity (GEO): EU Member States, EFTA countries, candidate countries, and potential candidates. 
6. Period of time (TIME): Energy flow data are annual.
7. Unit (UNIT): Energy flows are reported in Terajoules.

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.

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.
PEFA constitute satellite accounts to the National Accounts (NA). Hence, the statistical concepts and definitions of PEFA are derived from those of NA.
As far as applicable PEFA is also compliant with the statistical concepts and definitions internationally established for energy statistics: the International Recommendations for Energy Statistics (IRES).
Three concepts are essential to PEFA:
1) The concept of three generic types of energy flows as established in SEEA, namely:
a) natural energy inputs: flows from the natural environment into the economy such as fossil energy carriers in solid, liquid and gaseous form, biomass, solar radiation, kinetic energy in form of hydro and wind, geothermal heat etc.;
b) energy products: output flows from production processes as defined in national accounts (ESA); typically products produced by extractive industries, refineries, power plants etc.;
c) energy residuals: mainly energy in form of dissipative heat arising from the end use of energy products, flowing from the economy into the natural environment.
2) The accounting framework of (physical) supply and use tables as established in NA and SEEA;
3) The residence principle as established in NA and SEEA, i.e. PEFA records energy flows related to resident unit's activities, regardless where those occur geographically.

Data refer to activities of resident economic units in the sense of SEEA CF 2012 and national accounts (ESA), including households.

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.

The whole economic territory of the country, as well as its physical relation to economies in the rest of the world and the environment.

We use our national questionnaires:  Fuel and Energy Balance (EN-01), Electricity Distribution Survey (EN-12 and EN-17), Oil and Petroleum Products Balance Survey (EN-06), Fuel and Energy Consumption Statistical Questionnaire (EN-10), Quarterly Survey of Cross-Border Transactions of Non-Bank Enterprises (F-06). Additionally we use Supply and Use tables which are compiled by our National Accounts Division, and GHG emissions (Inventory report) from the Ministry of Environment of the Republic of Lithuania.

The main data sources you employ for the use of natural energy inputs is our national questionnaire - Fuel and Energy Balance (EN-01).

The main data sources you employ for the use of natural energy inputs is our national questionnaires: Fuel and Energy Balance (EN-01) and Oil and Petroleum Products Balance Survey (EN-06). 

The main data sources you employ for the transformation use by energy transforming entities (NACE 2-digit divisions) is our national questionnaire - Fuel and Energy Balance (EN-01).

The main data sources employ for the end use by end user entities (including non-energy use) is our national questionnaires:  Fuel and Energy Balance (EN-01) and Fuel and Energy Consumption Statistical Questionnaire (EN-10).

Supply and use tables (National accounts) are used in order to get information on commercial and services sector as well as to calculate use of transport fuels for the respective activities and households.

No.

The data were adjusted for the residence principle as follows: as regards road transport, energy use of diesel and gasoline for heavy-duty vehicles by resident and non-resident units were calculated using the statistics on goods/freight transport and formulas from the manual for emission accounts. We make an assumption that light vehicles fuel consumption for residents and non-residents are equal. As regards international aviation, calculations are based on the data from surveys EN-01 where companies provide data on "supply of jet fuels for airplanes". As regards international water transport, we use data from F-06 survey to calculate consumption in ships that fill up fuel outside the country.

 Annually.

For data collection for PEFA needs we use the national questionnaires:  Fuel and Energy Balance (EN-01), Electricity Distribution Survey (EN-12 and EN-17), Oil and Petroleum Products Balance Survey (EN-06), Fuel and Energy Consumption Statistical Questionnaire (EN-10), Quarterly Survey of Cross-Border Transactions of Non-Bank Enterprises (F-06).

PEFA is consistent with annual Fuel and Energy Surveys. In order to maintain accuracy, common indicators are compared. Values match.

When preparing the annual energy information, the values of the statistical indicators of the research period are summed up and grouped in various sections, and the aggregate statistical data indicators are analyzed.

The values of statistical indicators are compared with the results of the previous year, the search for a record of outstanding values is performed, the compatibility of statistical indicators is checked, the relations between statistical indicators (e.g. the ratio between consumed oil and produced oil products; between consumed fuel and produced energy); biofuel blending processes, etc.), errors that affect final results are sought.

In the case of significant deviations, the reasons for the deviation shall be explained. If necessary, statistical results are recalculated.

All electricity and heat supply was assigned to D35. Yes, it is fully aligned with our countries ESA monetary supply table.

Our method was to take the data on the use of energy products for road transport and distribute them between industries and households. The main data source for the compilation was Supply and Use tables from the National Accounts and our own data from the Energy Balance.

In the services sector, we use national accounts data to separate by 2 digit NACE for all fuels.

National Accounts supply and use tables  were utilised as the auxiliary data source to obtain NACE A*64 distribution key for the PEFA use tables which is also consistent to the breakdown data sources used in AEA. Additionally, PEFA and AEA share the same data sources and methodolodgy for the resident principle and road transport allocation.
