Activities of heat plants
Data on activities of heat plants are compiled with an aim to find out the number of heat plants, volume of heat produced, capacity.
Terms and definitions
Heat plant is energy transformation production unit producing heat for sale.
Heat plant consists of one or several devices producing heat (boilers).
Heat plants are divided into:
- public heat plants primary activity of which is generation of heat (division 35 of NACE Rev. 2);
- autoproducer heat plants are generating heat for their own use and partly for sale (NACE Rev. 2, except division 35 of NACE Rev. 2).
Total installed heating capacity
Heat produced during the year by public combined heat and power plants and heat plants and autoproducer heat and power plants and heat plants producing heat for sale.
Survey method and data source
Data are acquired with the help of full-scope survey from several data sources:
- CSB annual statistical report form 1-energy "Report on production of heat and electricity";
- Annex to the CSB annual statistical report form "Annex to report 1-energy";
- CSB statistical report form 2-EK "Report on purchase and use of energy resources".
Information is compiled on all branches of national economy. Data in breakdown by fields are compiled by the main kind of economic activity. Until 2012 data of the table ENG100. Number of heat plants, capacity and produced heat data on heat produced in autoproducer heat plants differ from the information in energy balance, as transformation sector of the energy balance (in compliance with the international methodology) covers data on heat produced for sale in autoproducer heat plants.
Heat plants producing heat for sale. Heat plants using fuel only for heating and technological needs are not surveyed. Consumption of fuel in these heat plants is shown in the energy balance – "final consumption".
Data are compiled and published in compliance with:
- Statistical Classification of Economic Activities (NACE Rev. 2);
- Classification of Administrative Territories and Territorial Units of the Republic of Latvia (CATTU);
- Combined Nomenclature (CN).
