Electricity production from CHP units minimally increased in 2008 but was still far below the 2010 target. New impetus to this field is expected to come from the new incentives scheme in force since November 2009.
The indicator shows the combined production of heat and electricity in Slovenia, which is one means of increasing the efficiency of electricity generation, as it makes use of the heat that is otherwise lost in conventional thermal power plants. Total heat is considered in heat production.

Data for Slovenia and other countries
Objectives summarised by: Resolucija o Nacionalnem energetskem programu (Resolution on the National Energy Programme, ReNEP, OG RS, No. 57/04).
Source database or source: Data on electricity and heat production and the use of fuels in CHP units were used for the indicator; the data were communicated by the Statistical Office of the Republic of Slovenia. Furthermore, data on ECHP gross electricity production for the period 2002-2008 were also used. The data before 2002 are not usable due to a new methodology.
For a comparison of Slovenia with the EU, the data of EUROSTAT were used, which were published in the publication Data in focus, Combined Heat and Power (CHP) in the EU, Turkey and Norway – 2007 data - Issue number 28/2009 in Combined Heat and Power (CHP) in the EU, Bulgaria, Romania and Turkey - 2004 data and data on the share of generated electricity in CHP plants in the total electricity production (Combined heat and power generation - Percentage of gross electricity generation Energy and the Environment), which is indicated among the structural indicators (Structural indicators > Environment > Combined heat and power generation).
Data administrator: Statistical Office of the Republic of Slovenia – Jože Zalar and EUROSTAT.
Date of acquisition for this indicator: 5 December 2009
Methodology and frequency of data collection for the indicator: The data on combined heat and power generation were prepared in accordance with EUROSTAT methodology, which determines two different ways of calculating the electricity production in CHP plants with regard to the total efficiency of the power plant. If the average annual efficiency (heat and power generation) is higher than 75 %, then all electricity is considered as CHP production. If the efficiency is lower, then the electricity production from CHP plants is calculated by multiplying the CHP heat production by the characteristic power-to-heat ratio of the plant. The data of SORS are not published; however, the data of EUROSTAT were published in publications, accessible through the Internet. Data collection is conducted on an annual basis. The data on CHP exist for Slovenia for the period 2002-2008. The data for the EU-27 are available for 2002 and 2004-2007.
Data processing methodology: Average annual rate of growth of electricity use is calculated as [(last year/base year) ^ (1/number of years) –1]*100.
The share of electricity production from CHP plants in the total electricity production was calculated as a quotient of gross electricity production in CHP plants and the total electricity production in Slovenia (See EN17, Electricity production by fuel).
Geographical coverage: The EU-25 includes the following EU Member States: Austria, Belgium, Cyprus, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Poland, Portugal, Republic of Ireland, Slovakia, Slovenia, Spain, Sweden, and the United Kingdom.
