The Overall energy balance sheet shows data on resources, transformation and final consumption of all forms of energy. Includes detailed indicators for fuels used and produced fuels/energy from transformation processes: in power plants, heat plants, petroleum refineries, coke and blast-furnace plants, coal briquetting plants. Final consumption of energy products is divided by: non-energy and energy consumption, as energy consumption is presented by economic activity groups (according to the used by Eurostat structure), which ensure international comparison of data.

• National Classification of Economic Activities (NCEA-2003, for international use NACE.BG-2003) is valid от 2007
• Classification of Economic Activities (CEA-2008, for international use NACE.BG-2008) in force as of 2008
• Nomenclature of energy products as part of Nomenclature of Industrial Production (PRODCOM.BG) is valid to 2007
• Nomenclature of energy products (PRODENERGY) in force as of 2008.

Includes data from all producers, importers and exporters, and consumers of primary and transformed energy products of all economic activities in accordance with the Regulation (ЕО) № 1099/2008 of the European Parliament and of the Council of 22 October 2008 on energy statistics.

Overall energy balance is aggregated table of the balances of all energy presented by groups:

• Solid fossil fuels
• Oil and petroleum products
• Natural gas
• Renewables and biofuels
• Non-renewable waste
• Nuclear energy
• Heat
• Electricity.

Overall energy balance is presented by three matrices:

• Primary energy
• Transformed energy
• Final energy consumption.

Not applicable.

Aggregated information by groups of energy products is comparable with the information prepared by the other member states as it is produced according to a unified methodology.

Information is used for analytical, forecasting and managing needs by Ministries and other agencies and organizations.

No information available for users of these data, as they have free access to the website of NSI. No user satisfaction survey has been carried out for this dataset.

Data fully meet the requirements of the Regulation (EC) No 1099/2008 of the European Parliament and of the Council of 22 October 2008 on energy statistics in terms of the scope of energy products and structure of consumption.

Data are reliable, the accuracy is good.

Not applicable.

Up to 5% statistical error due to incomplete coverage of the respondents, wrong data declared by the respondents, missing data or measurement errors. The mechanism of verification includes editing of data.

Data from respondents collected for preparation of the Overall energy balance is collected three months after the reporting year. Analysis, verification and preparation of Energy balances and Overall energy balance are carried till the end of November following the reporting year.

Data are published according to the Release Calendar of NSI.

Data are geographically comparable for the entire period for which they are available (since 2001).

Data are comparable over time for the entire period for which they are available (since 2001).

Not applicable.

There is no established policy on revisions.

Revision is made in result of changes in methodology, in classification used, or in case of incorrect data - omissions or inaccuracies in data provided by the respondents.

Main data sources for the compilation of Overall energy balance are statistical surveys (included in the National Statistical Programme) for energy products by producers, importers and exporters, and consumers (non-financial enterprises composing a balance), as well as administrative information.

Yearly.

Information is provided by conducting statistical surveys on energy products online or through electronic forms:

• Consumption of fuel and energy - online by “Business Statistics” Information System
• Production and sales of energy products - online by “Business Statistics” Information System
• Balance of energy transformation processes - by email
• Electricity and heat generation - by email
• Supply of liquid biofuels - by email
• Characteristics of solar collectors - by email
• Statistics on nuclear energy - by email
• Electricity, heat, natural gas, solid and liquid fuels supplied to end-users - by email.

A comparative analysis of the data from respondents is made with the data from other statistical surveys, with administrative data and with data from previous periods. Validated primary data are used for construction and preparation of 78 balances of energy products that have production and consumption in the country. Each energy product has its own specificity and reporting methodology, so the data analysis is done for each energy balance individually and for all indicators.

Statistical difference between resource and consumption of every balance should be reduced below 5 %.

Validated (ready) Energy balances are aggregated according to the scheme of the Overall energy balance.
