3.4. Statistical concepts and definitions Statistical characteristics of statistical observations.

Biodiesel – fuel produced from vegetable fats, animal fats and processed used frying oils.

Bioethanol – ethanol produced from biomass and/or biodegradable fraction of waste.

Biofuel – liquid fuel and gas fuel produced from biomass and used in transport (bioethanol, biodiesel).

Boiler – equipment for the production of steam or hot water using heat generated from the combustion of fuels.

Boiler-house – boiler equipment with the building and other facilities for the production of heat with heat carrier (steam or hot water). Boilers are not heating equipment or furnaces where the generated heat is transmitted directly without heat carrier.

Combined heat and power (CHP) – production of both heat and electricity from fuel combustion.

Converted energy (transformation output) – energy from converting primary energy, including electricity, heat, peat briquette, shale oil and oil shale coke and generator gas.

Electricity generated from renewable energy sources – ratio between the electricity produced from renewable energy sources and the gross national electricity consumption.

Energy dependency – shows the extent to which an economy relies on imports to meet its energy needs. It is calculated as a ratio of the difference of imports and exports to total consumption.

Energy intensity of the economy – the gross inland consumption of energy divided by GDP at constant prices. It measures the energy consumption of an economy and its overall energy efficiency.

Final consumption of energy – energy, which is received and consumed after conversions into other forms of energy (electricity, heat, fuel). Final consumption excludes the use of energy for non-energy purposes, own consumption by power plants and losses.

Final consumption of energy = primary energy supply + production of converted energy – consumption for conversion into other types of energy – own consumption of the energy sector – consumption for raw material – losses.

Fuels used for non-energy purposes – oil shale, natural gas and liquid fuel used as lubricating oil that are used as raw materials in the chemical industry.

Marine bunkering – quantities of fuels delivered to sea-going ships of all flags.

Primary energy – naturally sourced energy, which is consumed directly without conversion into other forms of energy. Primary energy sources in Estonia are oil shale, peat, firewood, wood chips, wood waste and biogas, but also coal, natural gas, liquefied gas, heavy fuel oil, light fuel oil, diesel, motor gasoline and aviation gasoline, which are imported.

Public power plants – undertakings whose primary activity is the generation of electricity for sale.

Renewable energy – energy from non-fossil sources (wind, solar, geothermal, wave, tidal, hydropower, biomass, landfill gas, sewage treatment gas and biogases).

Resources of primary energy – sum of stocks at the beginning of the year, production and imports.

Share of biofuels in total fuel consumption in transport – the percentage of biofuels in total fuel consumption in transport. Liquid biofuels include bioethanol (ethanol produced from biomass and/or biodegradable fraction of waste), biodiesel (a diesel quality liquid fuel produced from biomass or used fried oils), biomethanol (methanol produced from biomass and/or the biodegradable fraction of waste), biodimethylether (a diesel quality fuel produced from biomass and/or the biodegradable fraction of waste) and bio-oil (a pyrolysis oil fuel produced from biomass).

Share of renewable energy in gross final energy consumption – the contribution of renewable energy to gross final energy consumption.

Statistical difference – the difference between final energy available for consumption and actual final energy consumption.

Supply of primary energy (gross inland consumption) – equivalent to total consumption including the losses in transport and in distribution; primary energy resources less exports and stocks at year end.

3.5. Statistical unit Entity for which information is sought and for which statistics are ultimately compiled.


3.6. Statistical population The total membership or population or "universe" of a defined class of people, objects or events.

Basic data on energy quantities are in fuel specific units, e.g. liquid fuels in thousand tonnes, electricity in kilowatt-hours, while structural data on the capacity of installations are in megawatt, thousand tonnes per year (production capacity) or thousand square meters of installed surface in case of solar panels. The basic energy quantities data are converted to energy units, i.e. in terajoules and tonnes of oil equivalent to allow the addition of different nature fuel types.

Production, imports, exports and sales of electricity; production of heat – gigawatt hour, terajoule

Consumption of fuel for energy production – natural unit (depending on the type of fuel), terajoule; cost of consumed fuel – thousand euros

Stocks – natural (depending on the type of fuel), terajoule

18. Statistical processing

18.1. Source data Characteristics and components of the raw statistical data used for compiling statistical aggregates.


Total population is 70,000 objects. The sample includes 8,000 objects.

All companies are observed whose main economic activity is: production of wood for energy; extraction of peat; mining of shale oil; manufacture of coke and refined petroleum products; electric power generation, transmission and distribution; steam and air conditioning supply; trade of gas through mains; wholesale of solid, liquid and gaseous fuels and related products; passenger rail transport, interurban; freight rail transport; water transport; air transport; scheduled passenger transport by tramway and trolleybus; storage services of liquids and gases.

A simple random sample by number of employed persons is drawn from enterprises, institutions and organisations with the secondary main activity.


An extensive outturn account is received from the information system of governmental accounts of the State Shared Service Centre: maintenance costs of registered immovables, buildings, premises, real estate investments and structures (heating and thermal heat – accounts 551100, 551120, 551130, 551200; electricity – accounts 55101, 551121, 551131, 551210), vehicle maintenance costs (fuel – account 551300). Number of objects: 2,000.

Data on stocks in excise warehouses and inland consumption of liquid fuels are received from the Estonian Tax and Customs Board.

Data on heat pump usage level are received from the Estonian Heat Pump Association. Data on sources of pollution received from the Estonian Environment Agency are used for pre-filling questionnaire “Energy”.


Data from statistical activity 22303 “Foreign trade” are used.

18.2. Frequency of data collection Frequency with which the source data are collected.


18.3. Data collection Systematic process of gathering data for official statistics.

Data are collected and the submission of questionnaires is monitored through eSTAT (the web channel for electronic data submission). The questionnaires have been designed for independent completion in eSTAT and include instructions and controls. The questionnaires and information about data submission are available on Statistics Estonia’s website at https://www.stat.ee/andmete-esitamine (in Estonian).

Data are collected with the annual official statistics questionnaires “Elektrijaam”, “Energia” and “Tarbitud kütus ja energia”.

18.4. Data validation Process of monitoring the results of data compilation and ensuring the quality of statistical results.

Arithmetic and qualitative controls are used in the validation process, including comparison with other data. Before data dissemination, the internal coherence of the data is checked.

18.5. Data compilation Operations performed on data to derive new information according to a given set of rules.

In the case of missing or unreliable data, estimate imputation based on established regulations will be used. The data of the enterprises that did not submit the questionnaire are replaced with the corresponding data averages of similar enterprises. Administrative data are used for checking and imputation.

Variables and statistical units which were not collected but which are necessary for producing the output are calculated. New variables are calculated by applying arithmetic conversion to already existing variables. This may be done repeatedly, the derived variable may, in turn, be based on previously derived new variables.

For statistical units weights are calculated, which are used to expand the data of the sample survey to the total population.

Microdata are aggregated to the level necessary for analysis. This includes aggregating the data according to the classification, and calculating various statistical measures, e.g. average, median, dispersion, etc.

The collected data are converted into statistical output. This includes calculating additional indicators. In order to obtain data about the energy consumption of households, non-regular surveys are organised over a few years. In the years when the survey does not take place, data are estimated based on the data structure of the previous survey, the data of enterprises selling fuel and the data from the Household Budget Survey. The last survey on household energy consumption took place in 2011.

18.6. Adjustment The set of procedures employed to modify statistical data to enable it to conform to national or international standards or to address data quality differences when compiling specific data sets.
