Non-application of consumption principles on several
consumption groups;
Non-coverage of all energy products
Absent of commodity balance conversion factors (TOE)
applied in international practice;
Non-calculation of “statistical difference” indicator

To achieve more transparency and effectiveness of energy sector applying
international statistics standards in the country;
To determine the development trends of energy sector to make statistical
application and analysis of changes and inclinations taken place in production
and consumption structure of energy products;
To provide the country government with essential statistical information on
compilation of national Energy balance, making decisions on energy fields
for the next years.

Enhance the relevance of energy statistics by providing comprehensive and reconciled data on the energy
situation on a national territory basis;
Provide comprehensive information on the energy supply and demand on the national territory in order to
understand the energy security situation, the effective functioning of energy markets and other relevant
policy goals, as well as to formulate energy policies;
Serve as a quality tool to ensure completeness, consistency and comparability of basic statistics;
Ensure comparability between different reference periods and between different countries;
Provide data for estimation of CO2 emissions with respect to national territory;
Provide the basis for indicators of the energy’s role in the country’s economy;
Calculate efficiencies of transformation processes occurring in the country (e.g., refining, electricity
production by combustion of fuels, etc.);
Calculate the relative shares of the supply/consumption of various products (including renewable versus
non-renewable) of the country’s total supply/consumption;
Provide an input for modeling and forecasting.

“Statistical differences”
In the energy balance, the statistical difference is the numerical
difference between the total supply of a energy product and the total use
of it. It is presented in line 2 of the energy balance.

To accept the new recommendations on the basis of International Recommendations for Energy
Statistics which is considered as unique methodology on energy statistics;
To conduct the “sample survey on Energy consumption of natural persons (private owners)” for
the purpose of indication of energy products consumed by natural persons by the sectors in final
consumption sector of energy;
To prepare the methodological explanations on estimation of unobserved part in the sector of
energy balance final consumption, as well as data on households and private owners;
To prepare new indicators by training of advanced experiences in energy statistics;
To prepare the methodological conception on the system of statistical processes management
regarding to energy statistics and energy balance compilation;
To prepare the metadata system on reports applied in energy statistics;
To continue the constant improvement of data quality;
Etc.
