3.1. Data description | ||||||||||||
European statistics on electricity prices for household and final non-household customers. |

||||||||||||
3.3. Coverage - sector | ||||||||||||
Household sector and final non-household sector (industry, services, offices, agriculture, etc). |
||||||||||||
3.4. Statistical concepts and definitions | ||||||||||||
The prices are reported in national currencies per kWh and according to different bands of consumption. For the household sector, these bands are:
For the final non-household sector, the bands are:
There exist 2 different levels of disagregation for semestrial and annual prices: 1- Semestrial prices: These prices are reported twice a year and are divided in 3 levels:
2- Annual prices: These prices are reported once a year together with the data for the second semester and are divided into the following components and taxes:
In addition to these elements, the network cost is split into the respective shares of transmission and distribution. The relative share of consumption in the different consumption bands is reported by the countries and used to calculated the single national electricity prices (weighted averages for consumer bands IA-IF and DA-DE) but not published because it could be used to re-calculate some confidential values. Some of the taxes are refundable. Here is a description of them:

Prices are reported in national currency per kWh. However, Eurostat also calculates and publishes the prices in EURO and PPS (purchasing power parity). |
|
|||
For semestrial prices, the reference periods are from January to June for semester 1 and from July to December for semester 2. For annual prices, the reference period is the whole calendar year (from January to December). |

|
|
|||
10.1. Dissemination format - News release | |||
First Releases are published on a SURS’s website according to a pre-announced release calendar and at the same time data are published in a publicly accessible data base (SiStat database). |
|||
10.2. Dissemination format - Publications | |||
Data is also disseminated (published) in annual national statistical publications:
Published in non-statistical publications:
|
|||
10.3. Dissemination format - online database | |||
There are following on-line databases:
|

It is estimated that there are around 2000 annual page visits to the SiStat databse tables of electricity prices. |
|||
10.4. Dissemination format - microdata access | |||
Microdata is not available on SURS, since SURS obtains data from administrative source in an aggregated form. Data are being collected in EPOS administrative database (operated by Energy Directorate, Ministry of Infrastructure). |
|||
10.5. Dissemination format - other | |||
No other dissemination format. |
|||
10.5.1. Metadata - consultations | |||
These is no data available on number of consultations within a statistical domain for a given time period. |
|||
10.6. Documentation on methodology | |||
Methodological explanation: https://www.stat.si/StatWeb/File/DocSysFile/8313/18-143-ME.pdf |
|||

|
|||
11.1. Quality assurance | |||
At the end of every survey (i.e. on annual level, if not determined otherwise), annual quality report (which is in many points simmilar to this, provided by Eurostat) is prepared. Quality guidelines are closely followed by all staff. Training courses, use of best practices (from other institutions, both domestic and foreign), self-assesments and other necessary processes are also a part of quality assurance framework within the unit and institution. |
|||
11.2. Quality management - assessment | |||
The current statistical outputs are estimated as optimal. Data collecting, processing and the dissemination process are verified. No quality improvements are planned in the near future. |
|
|||
12.1. Relevance - User Needs | |||
Data are freely available to general public. Users are researchers, students, governmental and non-governmental institutions, companies etc. We recorded some demand from users for longer time-series (prior to 2nd semester of 2007). The data on electricity prices prior to 2nd semester of 2007 is however not fully comparable to newer data because of diffenerent methodological process. This is also why extending the time-series (back) is not forseen. |
|||
12.2. Relevance - User Satisfaction | |||
User satisfaction surveys are being carried out on an institutional level and not for certain survey (e.g. energy prices). Users can however directly contact the statistitian responsible for the survey (e-mail address and phone number are provided in SiStat database portal), but this is mostly used for data inquries. |
