Data for Slovenia and other countries

Objectives summarised by: Resolucija o Nacionalnem energetskem programu (ReNEP)(Resolution on the National Energy Programme, Official Gazette of the RS, No. 57/04) in Directive (2003/96/EC) on the taxation of fuels and electricity.

Source database or source: The data on prices of energy products (prices before taxes, prices without VAT and prices with all taxes) are published by SORS on the SI-STAT Data Portal > Environment and natural resources > Energy > Prices of energy sources for all consumer groups.

Data administrator: Statistical Office of the Republic of Slovenia (Mojca Suvorov) and Eurostat.

Data acquisition date for the indicator: 5 December 2009.

Methodology and frequency of data collection for the indicator: The data for energy prices are published twice a year; namely, the prices in force on 1 January are published by SORS in the second week of March, and the prices of 1 July of the current year by SORS in the second week of September.
SORS has been collecting data since 1992 for electricity and since 1995 for natural gas. The prices of oil derivatives have been available since 1999; the data on prices and taxes before that year are available at Petrol.
The most representative consumer groups for industrial consumers of natural gas and electricity are I3 for consumers of natural gas and Id for consumers of electricity. For household consumers, the most representative consumer groups are D2 for consumers of natural gas and Dc for consumers of electricity.

Data processing methodology: The energy prices published by SORS are current prices. Since these are nominal categories, changes in prices do not reflect real changes. Real changes in prices and taxes are reflected only by real prices and taxes, which are calculated by the deflation of nominal prices with the GDP deflator, which is published by SORS for every previous year. The energy tax that is indicated in the data sheet is the real tax; deflators that converted nominal tax to the level of real tax of 1995 were used for the calculation. The real tax of 1995 was converted into EUR 1995 with the use of the average annual exchange rate of the Bank of Slovenia in 1995. Such a calculation enables better comparability of energy taxes in Slovenia with average taxes in the EU.
Real energy taxes are calculated as:

TR_t = [(R_t*1/D_1995,t)/er₁₉₉₅]

PR-real prices, P – current prices, D – deflator, er – exchange rate.

Geographical coverage: The EA-15 (Euro Area) is composed of: Austria, Belgium, Cyprus, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, Malta, the Netherlands, Portugal, Spain, and Slovenia. EA-16 = (From 1 January 2009 EA-15 + Slovakia). The EU-15 includes old EU Member States (Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, the Netherlands, Portugal, Spain, Sweden, the United Kingdom). The EU-10 includes Member States that joined the EU in 2004 (Cyprus, Czech Republic, Estonia, Hungary, Lithuania, Latvia, Malta, Poland, Slovenia, Slovakia). The EU-12 includes, besides the EU-10, Bulgaria and Romania. The EU-27 includes the EU-15 and EU-12, while the EU-25 includes the EU-15 and EU-10.

Information concerning data quality:
- Advantages and disadvantages: The source of basic data for the entire time series for electricity and natural gas is SORS, which enables a more efficient and consistent analysis of individual sectors; only for fuel tax before 1999, it was necessary to obtain data from the largest fuel dealer in Slovenia (Petrol).
- Relevance, accuracy, robustness, uncertainty:
Reliability of the indicator (archive data): The data reflect the prices by individual consumer groups that were in force on the first day of January and July.
Uncertainty of the indicator (scenarios/projections): Scenarios and projections are not available.
- Overall assessment (1 = no major comments, 3 = data to be considered with reservation):
Relevance: 1
Accuracy: 2
Completeness over time: 1
Completeness over space: 1
