DEFINITIONS

Autoproducers power plants – enterprises, both privately or publicly owned, which generate electricity and/or heat wholly or partly for their own use as an activity which supports their primary activity.

Average cost of energy and fuels – ratio of expenses to the quantity of fuel or energy in enterprises during the year.

Boiler – equipment for the production of the steam or hot water using the fuels for that purposes.

Boiler-house – equipment supporting the production of heat with heat carrier (steam or hot water). Heating equipment where heat is used directly for the technological purposes is excluded.

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

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

Enterprise an enterprise consists of one or more companies (public limited company, private limited company, limited partnership, general partnership, commercial association) or branches of foreign companies or sole proprietors.Energy statistics do not cover branches of foreign companies and sole proprietors.

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, self-consumption by power plants and losses.

Fuels used for non-energy purposes – quantities of fuels used for purposes other than the production of energy, such as raw materials in the chemical industry (oil shale and natural gas) and liquid fuel used as lubricating oil.

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

Primary energy – energy, which is consumed directly without converting it previously 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 – enterprises, both privately or publicly owned, which generate electricity and/or heat for sale to third parties, as their principal activitys.

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

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

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

Supply of primary energy (gross inland consumption) – equivalent to total consumption including the losses in transport and in distribution. Primary energy supply should be equal to resources of primary energy minus fuels in stocks at the end of the year and exports.

METHODOLOGY

Data on energy are collected from all enterprises that produce, sell or store fuels, electricity or heat. Also, all enterprises of rail, water and air transport activities are enumerated. Data on other energy consumers are collected with a sample survey. The total survey population includes all economically active units. Units with at least 50 employees are enumerated completely. A simple random sample is drawn from the rest of enterprises.

The energy consumption indicators of the public sector have been calculated using the data obtained from the Ministry of Finance’s database for the expenditure of energy. For obtaining the household energy consumption data, irregular studies are conducted over several years. In the intermediate years, the data evaluation is based on the previous survey, on the data from enterprises selling energy and on the data received from the Household Budget Survey. The last survey for household energy consumption was conducted in 2011.

Data on the imports and exports of fuels and energy have been received from the Foreign Trade Statistics Service of Statistics Estonia, and the data on liquid fuels have been revised on the basis of the data of the Estonian Tax and Customs Board.

The quantities of fuels in natural units have been recalculated into terajoules based on average calorific values obtained from the producers and importers of fuels.

The data are based on the Regulation (EC) No 1099/2008 of the European Parliament and of the Council of 22 October 2008 on energy statistics.
