3.2.1. Supply and transformation sectors

The following specific definitions apply to aggregates for electricity and heat in this chapter: Gross electricity production: the sum of the electrical energy production by all the generating sets concerned (including pumped storage) measured at the output terminals of the main generators. Gross heat production: the total heat produced by the installation and includes the heat used by the installation's auxiliaries which use a hot fluid (space heating, liquid fuel heating etc.) and losses in the installation/network heat exchanges, as well as heat from chemical processes used as a primary energy form. Net electricity production: the gross electricity production less the electrical energy absorbed by the generating auxiliaries and the losses in the main generator transformers. Net heat production: the heat supplied to the distribution system as determined from measurements of the outgoing and return flows. The aggregates mentioned in the next table must be declared separately for main activity producer plants and for autoproducer plants. Within these two types of plants, both gross and net electricity and heat production must be declared for electricity only, for CHP and for heat-only plants separately wherever applicable, for the following aggregates: 1. Total production 1.1. Of which: nuclear 1.2. Of which: hydro 1.2.1. Of which: part of hydro produced from pumped storage 1.3. Of which: geothermal 1.4. Of which: solar 1.5. Of which: tide, wave, ocean 1.6. Of which: wind 1.7. Of which: combustible fuels Fuels capable of igniting or burning, i.e. reacting with oxygen to produce a significant rise in temperature and combusted directly for the production of electricity and/or heat. 1.8. Of which: heat pumps Heat output from heat pumps only where the heat is sold to third parties (i.e. in cases where production occurs in the transformation sector). 1.9. Of which: electric boilers Quantities of heat from electric boilers where the output is sold to third parties. 1.10. Of which: heat from chemical processes Heat originating from processes without input energy, such as a chemical reaction. Excludes waste heat originating from energy-driven processes, which should be reported as heat produced from the corresponding fuel. 1.11. Of which: other sources — electricity (please specify) The aggregates mentioned in the next table must be declared as totals, for electricity and heat separately, wherever applicable. For the three first aggregates in the next table, quantities should be calculated from and be compatible with the values declared according to the previous table. 1. Total gross production 2. Own use by plant 3. Total net production 4. Imports See also explanation under 5 ‘Exports’. 5. Exports Amounts of electricity are considered as imported or exported when they have crossed the political boundaries of the country, whether customs clearance has taken place or not. If electricity is transited through a country, the amount should be reported as both an import and an export. 6. Used for heat pumps 7. Used for electric powered steam boilers 8. Used for pumped storage 9. Used for electricity production 10. Energy supplied For electricity: the sum of the net electrical energy production supplied by all power stations within the country, reduced by the amount used simultaneously for heat pumps, electrically powered steam boilers, pumping and reduced or increased by exports to or imports from abroad. For heat: the sum of the net heat production for sale by all plants within a country, reduced by heat used for electricity production and reduced or increased by exports or imports from abroad. 11. Transmission and distribution losses All losses due to transport and distribution of electrical energy and heat. For electricity, includes losses in transformers which are not considered as integral parts of the power plants. 12. Total consumption (calculated) 13. Statistical difference 14. Total consumption (observed) The electricity produced, the heat sold and the fuel quantities used, including their corresponding total energy (based on their net calorific value except for natural gas which is based on gross calorific value) from the combustibles listed in the next table must be declared separately for main activity producer plants and for autoproducer plants. Within these two types of plants, this electricity and heat production must be declared for electricity (only) plants, for CHP and for heat (only) plants separately wherever applicable: 1. Solid fuels and manufactured gases: 1.1. Anthracite 1.2. Coking coal 1.3. Other bituminous coal 1.4. Sub-bituminous coal 1.5. Lignite/brown coal 1.6. Peat 1.7. Patent fuel 1.8. Coke oven coke 1.9. Gas coke 1.10. Coal tar 1.11. BKB (brown coal briquettes) 1.12. Gasworks gas 1.13. Coke oven gas 1.14. Blast furnace gas 1.15. Oxygen steel furnace gas 2. Oil and petroleum products: 2.1. Crude oil 2.2. NGL 2.3. Refinery gas 2.4. LPG 2.5. Naphtha 2.6. Kerosene type jet fuel 2.7. Other kerosene 2.8. Gas/diesel (distillate fuel oil) 2.9. Heavy fuel oil 2.10. Bitumen (including orimulsion) 2.11. Petroleum coke 2.12. Other oil products 3. Natural gas 4. Renewable energy and energy from waste 4.1. Industrial waste (non-renewable) 4.2. Municipal waste (renewable) 4.3. Municipal waste (non-renewable) 4.4. Wood, wood waste and other solid waste 4.5. Landfill gas 4.6. Sewage sludge gas 4.7. Other biogas 4.8. Liquid biofuels
