Annual data on quantities of Electricity, Heat, Coal, Blast-Furnace Gas Oil and Oil Derivatives, Natural gas, Renewable energy sources cover the entire energy sector from supply, through transformation to final consumption by sectors and type of fuel. Also, annual data on stocks, import and export for various energy products are included. The Statistical Office of the Republic of Serbia (SORS) started to establish statistics of Annual Energy Balances in 2005 year. All data are presented in the form of energy balance in accordance with Eurostat recommendations. Data for each energy source are given in the natural unit of measure and also in TJ.

Data on Final energy consumption in household by purpose were started to send in accordance to Eurostat requirements and deadline. First time data were sent for 2015, with back time series from 2010 year. For the questionnaire on Final energy consumption in households, it does not conduct a special survey, there is no special, regular way of  "National data collection". Data for the questionnaire "Disaggregated Final Energy consumption in households" are provided on the basis of a project that was conducted for the needs of our Ministry of Mining and Energy. One of the results within the project was the structure of energy consumption in households, by purpose of consumption. The structure obtained on the basis of the project is used by statistics for the dissahregation of total data for households (from the energy balance) in order to fill out the questionnaire "Disaggregated Final Energy consumption in households".

After the validation proces SORS sents Five Joint Annual Questionnaires to Ministry of Mining and Energy. Based on Five Joint Annual energy questionnaires, that are validated from Eurostat, Ministry of Mining and Energy provides and send SHARE questionnaire to Eurostat. 

Through the monthly energy statistics are presented data of Electricity, Solid fuels, Natural gas, Oil and Petroleum products. Key variables are monthly produced, imported, exported, stored and consumed amounts of solid, liquid and gaseous commodities. For each of the mentioned commodities the data are delivered to Eurostat via separate dedicated questionnaires. All definitions and data are presented according to requirements of Annex A and Annex C of the Regulation 1099/2008 and all its Amendments. 

- National classification of economic activities - KD(2010) based on NACE Rev.2 classification (Statistical Classification of Economic Activities in the Europian Community, Rev.2).

- Definition of energy/energy commodities and energy flows given in the Regulation (EC) No 1099/2008 and its Amendments, are applied.

Energy statistics data cover sectors of the economy which are involved in production (energy sector 05,06,19,35 CD NACE Rev.2), selected business entities whose main activity do not belong to energy sector, trade and energy consumption, industrial sector-without area that are belong to energy sector, construction, transport, households, agriculture and others -commercial and public services). 

Monthly energy data cover mainly the supply side (production, trade, export, import, stocks) and to a lesser extent the consumption side. By  the monthly energy statistics are presented data of Electricity, Solid fuels, Natural gas, Crude oil & Petroleum products. Data are presented in a natural measure unit and TJ. Data are available since January 2015 for Electriciy and Solid fuels; for Natural Gas since January 2017 year and for Crude oil & Petroleum products since 2020 year.

Definitions, concepts and methodolgy for making energy balance are harmonized with established standards according to recommendations of the Regulation (EC) No 1099/2008 and its Amendments. The definitions in Annex A and Annex B of Regulation (EU) No 1099/2008 and its amendments have been fully applied. The relationship between products and energy flows, follows the standard principlies of the energy balances.

See table under 3.5.1.

Reporting units are energy entities (enterprises) that perform the activity of production, supply, distribution and trade in energy products and which have a license to perform that activity. Selected business entities whose main activity are not in energy sector, but generate electricity or heat wholly or partly for their own use as an activity which supports their primary activity.

The scope of the energy sector (producers, suppliers, traders, energy distributors) is full; all those who produce energy /energy products and distributors are included. Traders have a range of about 85 to 100%, depending on the type of energy source. Industrial enterprises, of which we collect data, achieve 85% of the value added in industry. Construction companies are included with 95%, while transport companies are covered with 90% and agricultural cooperatives 100%.

Relationship of monthly and annual data is controlled and compared. Any significant deviations are controlled and checked in contact with the reporting units.

Not applicable.

The level of consistency, coherence in full cooperation with the reporting units is checked in detail. Checks include consistency of time series, detection of causes of deviations, efficiency of energy transformation processes, and application of other control systems.

Annual energy statistics: Not applicable.

Monthly energy statistics: Reporting units enter data electronically. Reporting units do not have costs related to data entry to the IMIS database. For the realised period data are entered by the 27th of the current month for the previous three months (they can also be entered monthly), and for the planning by 15.11. current year for the next year. For the needs of the monthly questionnaires filled in by the SORS, an upgrade of he IMIS database was upgrade, within which the "Reports" tab was created, with report tables created in accordance with the requests from the monthly questionnaires, for which data from the IMIS database is provided. The costs of maintaining and upgrading the IMIS database are borne exclusively by the Ministry.

Monthly Oil Statistics: Not applicable

Annual energy statistics: The scope of the energy sector is full, all those who produce energy/energy products and distributors are included. Traders have a range of about 85 to 100%, depending on the type of energy source. Industrial enterprises, of which we collect data, achieve 85% of the value added in industry. Construction companies are included with 95%, while transport companies are covered with 90% and agricultural cooperatives 100%.The energy balances are included the production of all producers of primary energy and transformed forms of energy. Accordingly, there was also a full coverage of energy consumption in the energy sector.

In the regular annual surveys that are included: hydro power plants, solar photowoltaic, wind energy, CHP, thermal power plants, autoproducers district heating plants, oil and gas extraction, refineires, petrochemical refinery, blast furnace plant, coal mines, coal transformation, lubricants factory,  producers of renewable energy (gepthermal, fuel-wood, biogas). Import / export data are taken from Depatement of Foreign Trade Statistics in SORS – Customs data), except data for electricity (data provides Serbian Transmission System and Market Operator), crude oil (data provides NIS company) and natural gas (data provides National gas company).

Data on the stocks at the beginning and end of the year SORS gets from energy producers, energy distributors, trade enterprises, industrial enterprises.

Showing losses depends on the type of energy (transfer, distribution or transport).

Final Non-energy consumption аre provided from industrial enterprises through a separate statistical survey.

Data on final consumption for energy purposes are based on the specific questionnaires created for energy producers, energy distributors, trade enterprises and industrial enterprises. In addition to, we used data collected by other Statistical Office`s departments within their statistical surveys (Department of Transport, Department of Agriculture and Department of Construction). Data of final energy consumption of biomass is taken from Ministry of Mining and Energy. If the reporting units do not answer all the questions from the questionnaire оr if any illogicality difference in data is noticed, the reporting units are contacted by telephone or email in order to provide the missing information or clarifications.

Data is controlled at the level of the reporting unit, and then at the summary level. If an error is detected, the data is corrected at the level of the reporting unit, and then the sum is re-summarized in order to compile the energy balance of the energy source.

Also, in cooperation with IT experts, automation (software solutions) has been established for the calculation of certain data.

Questionnaires for collecting data are available on the SORS web-site.

Monthly energy statistics : Data are taken from the Ministry of Mining and Energy (MoME). Reporting units are energy entities that carry out the activity of producing and trading of Electricity, Coal and Natural gas. Reporting units for Electricity, Coal and Natural gas submit data to the MoME by filling out a database (CAWI on-line questionnaire). The control of the entered data is carried out by the administrator of the IMIS database in cooperation with the persons responsible for data entry as well as with the SORS. SORS receive from MoME summarized data (output table). Within the IMIS database, it is possible to quickly check whether all users have entered data for a certain period as well as at the same time quick notification and communication with a large number of responsible persons of users who have failed to enter some data. Data on import and export of coal are taken from the SORS's Foreign Trade Departments.

Reporting units for Monthly Oil statistics submit data to the MoME by filling questionnaire that are define by the “Regulation on methods of data collection and processing and calculation of average daily net imports, average daily consumption and compulsory reserve quantities of petroleum and petroleum refined products"

Within 25 days from the end of the month to which the data relate, Ministry submits Tables in electronic form to the Statistical Office.  Statistical Office in cooperation with the MoME checks the month reliability of the submitted data, investigates possible deviations and requests explanations or corrections from taxpayers. Obligors that submit forms are obliged to respond to the request of the Statistical Office or MoME regarding the data from the submitted forms within seven days. Based on the submitted forms, for each month SORS  prepares a cumulative monthly Report on the Supply of crude oil, natural gas liquids, refinery raw materials, additives and other hydrocarbons and the Report on the Supply of finished products at the level of the Republic of Serbia. During the proccessing process, if deviations or illogicalities are noticed, the Ministry of Mining and Energy contacted reporting units in order to check the data. Within 55 days after the end of the reporting month, sumarized data are submit to MoME and to the Eurostat.

See table under 18.2.1.

Annual energy statistics: Data are collected in a paper form, only survey in the field of industry is conducted through the web questionnaire. Questionnaires are sent to the reporting units at the end of February, in the current for the previous year. Also, the questionnaires are located on the website, except for oil and derivatives questionnaires, due to constant underconstruction with the reporting units. Reporting units can send completed questionnaires by post, e-mail or fax. Telephone contacts are made in order to increase the number of responses as well as clarification of data.

Monthly energy statistics: For the realized period data are entered by the 27th of the current month for the previous three months (they can also be entered monthly), and for the planning by 15.11. current year for the next year. For the needs of the monthly questionnaires filled in by the Statistical Office (SORS),  IMIS database is upgrade, within which the Reports tab was created. Report tables are created in accordance with the requests from the monthly questionnaires, for which data from the IMIS database is provided.

For Monthly Oil statistics reporting units submit data to the Ministry of Mining and Energy (MoME) by filling questionnaire that are define by the “Regulation on methods of data collection and processing and calculation of average daily net imports, average daily consumption and compulsory reserve quantities of petroleum and petroleum refined products". Within 25 days from the end of the month to which the data relate, MoME submits Tables in electronic form to the Statistical Office (SORS).  In cooperation, MoME and SORS check the month reliability of the submitted data, investigates possible deviations and requests explanations or corrections from taxpayers. Obligors that submit forms are obliged to respond to the request of the MoME or SORS regarding the data from the submitted forms within seven days. Based on the submitted forms, for each month SORS  prepares a cumulative monthly Report on the Supply of Crude oil, Natural gas liquids, Refinery raw materials, Additives and Other hydrocarbons and the Report on the Supply of finished products at the level of the Republic of Serbia. During the proccessing data, if deviations or illogicalities are noticed, the MoME contact reporting units in order to check data. If the reporting unit send corrected data to the MoME, these data MoME send to the SORS again. After that data are summarized again.
