Energy balance data characterise production, imports, exports and consumption of energy resources in Latvia.
Data are collected with an aim to compile information on in compliance with the Annex B to the European Parliament and Council Regulation (EC) No 1099/2008 (22 October 2008) on energy statistics.
Terms and definitions
Production [energy resources]
Energy resources produced from natural raw materials. Production of electricity in hydropower plants and electric power plants.
Quantity of energy resources transported across the state border to the third countries and to the EU Member states (without commodity flows to customs warehouses and free economic zones), not including transit.
Quantity of energy resources transported across the state border from the third countries and from the European Union (EU) Member States (without commodity flows from customs warehouses and free economic zones), not including transit.
Transfers [oil products]
Result of oil product reclassification, which emerges from mixing of oil products or when using them as additive to other oil products.
Total consumption [energy]
Consumption of energy resources by transformation sector, energy sector, all sectors of national economy, as well as by households.
Gross consumption of charcoal
Gross consumption of charcoal is negative (Production + Imports – Exports + Stock changes + Statistical difference) because charcoal is produced from firewood, therefore production is shown in charcoal production item in the Transformation sector.
In this case charcoal balance is calculated as follows: Volume of charcoal produced in transformation sector + Imports – Exports + Stock changes + Statistical difference = Final consumption.
Transformation sector [energy]
Represents the value of fuel consumed for the production of electricity and fuel consumed for production of sold heat.
Final consumption [energy]
Consumption by industry, transport, households, agriculture, forestry, hunting, fishery, and other consumers (NACE Rev. 2 divisions 33, 36–39, 45–47, 52–96, 99).
Data collection and statistical processing
Survey method and data source
Energy balance data are acquired from several CSB surveys on the purchase and use of energy resources, supply of natural gas, production of heat and electricity, industrial production and sale, trade with third countries (EXTRASTAT) and trade with EU Member States (INSTRASTAT).
Data are acquired also from the Road Traffic Safety Directorate reference year information on the number of motor vehicles that have undergone roadworthiness tests and from the State Revenue Service report "Turnover of oil products (fuel)".
Information about the amount of electricity sold by electricity traders is obtained from JSC Sadales tīkls and JSC Augstsprieguma tīkls.
Information is compiled on all sectors of national economy. Data in breakdown by sectors are compiled by the main kind of economic activity.
Includes all economically active enterprises, budgetary institutions, foundations, associations, funds, peasant and fishermen farms, and religious organisations engaged in the production, imports, exports, consumption and sale of energy resources.
For the recalculation of energy balance to terajoules, conversion factors based on net calorific values are used.
The tonne of oil equivalent is a conventional standardised unit defined on the basis of a tonne of oil with a net calorific value of 41 868 kilojoules/kg. The conversion coefficients from the specific units to kgoe (kilogramme of oil equivalent) are thus computed by dividing the conversion coefficients to the kilojoules by 41 868.
Units and conversion factors:
|Units of measurements||GJ (gigajoule)||MWh (megawatthour)||TOE|
Energy balance data are compiled in compliance with:
- EU Combined Nomenclature;
- Statistical Classification of Economic Activities (NACE Rev. 2);
- Classification of Administrative Territories and Territorial Units of the Republic of Latvia (CATTU);
- List of products of the European community (PRODCOM) (each corresponding version).
