European statistics on electricity prices for household and final non-household customers.

Internal Eurostat classification system based on annual electricity consumption bands and tax levels.

Household sector and final non-household sector (industry, services, offices, agriculture, etc).

The prices are reported in national currencies per kWh and according to different bands of consumption.

For the household sector, these bands are:

• DA: customers consuming less than 1000 kWh.
• DB: customers consuming 1000 kWh or more but less than 2500 kWh.
• DC: customers consuming 2500 kWh or more but less than 5000 kWh.
• DD: customers consuming 5000 kWh or more but less than 15000 kWh.
• DE: customers consuming 15000 kWh or more.

For the final non-household sector, the bands are:

• IA: customers consuming less than 20 MWh.
• IB: customers consuming 20 MWh or more but less than 500 MWh.
• IC: customers consuming 500 MWh or more but less than 2000 MWh.
• ID: customers consuming 2000 MWh or more but less than 20000 MWh.
• IE: customers consuming 20000 MWh or more but less than 70000 MWh.
• IF: customers consuming 70000 MWh or more but less than 150000 MWh.
• IG: customers consuming 150000 MWh or more.

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:

• Level 1 prices: prices excluding taxes and levies.
• Level 2 prices: prices excluding VAT and other recoverable taxes and levies.
• Level 3 prices: prices including all taxes and levies.

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:

• Energy and supply: generation, aggregation, balancing energy, supplied energy costs, customer services, after-sales management and other supply costs.
• Network cost: transmission and distribution tariffs, transmission and distribution losses, network costs, after-sale service costs, system service costs, and meter rental and metering costs.
• Value added taxes (VAT): as defined in Council Directive 2006/112/EC.
• Renewable taxes: taxes, fees, levies or charges relating to the promotion of renewable energy sources, energy efficiency and CHP generation.
• Capacity taxes: Taxes, fees, levies or charges relating to capacity payments, energy security and generation adequacy; taxes on coal industry restructuring; taxes on electricity distribution; stranded costs and levies on financing energy regulatory authorities or market and system operators.
• Environmental taxes: taxes, fees, levies or charges relating to air quality and for other environmental purposes; taxes on emissions of CO₂ or other greenhouse gases. This component includes the excise duties.
• Nuclear taxes: taxes, fees, levies or charges relating to the nuclear sector, including nuclear decommissioning, inspections and fees for nuclear installations.
• All other taxes: taxes, fees, levies or charges not covered by any of the previous five categories: support for district heating; local or regional fiscal charges; island compensation; concession fees relating to licences and fees for the occupation of land and public or private property by networks or other devices.

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.

Value added tax is refundable for non-households cosnumers. It is reported in Level 3 prices. 

Household and final non-household consumers divided into consumption bands.

Household customers: Data coming from 16 suppliers and representing about 100 % of the household consumption.

Final non-household customers: Data coming from 26 suppliers and representing 75 % of the final non-household consumption.

Whole country. 

Electricity prices data for Slovakia are available since 2004. 

Not applicable.

Prices are reported in national currency per kWh. However, Eurostat also calculates and publishes the prices in EURO and PPS (purchasing power parity).
Relative shares of sub-component of the network component and consumption volumes are reported in percentages.

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).

Quality policy is defined and made available to the public in documents:

Quality declaration and Quality policy.The SOSR high level statements highlight customer orientation and quality of the SOSR products and services; this is then reflected in the development strategy of the SOSR for the given period of time in: Vision, mission, common shared values.

Quality Manual is covering all elements of the ISO 9001.

European Statistics Code of Practice is the backbone of the whole QMS.

All necessary issues related to data entry, data completeness and statistical controls are implemented in integrated statistical information system - ISIS. The cross-checking is done in the context of the statistical control process. A comparison with the development in previous periods is done.

Regarding the results of particular data production processes the overall quality of the electricity prices is considered to be as good. 

Key user is Eurostat. We navigate other users to Eurostat database.

User satisfaction is monitored via “Survey on satisfaction of users with products and services of the SO SR” conducted regularly with two-year periodicity. Evaluation of the user satisfaction survey also includes satisfactions rate (overall and for specified areas as well as for groups of products) and it is submitted together with conclusions and suggestions for improvements to top management meeting for approval. Energy statistics is not surveyed individually. In 2020, the overall customer satisfaction with the Office's products and services reached 82,1 points.

All legislation requirements are fulfilled.

100 %

Most of checks are realised in the process of data entry automatically (number range, relations among the variables). Checks are realised also on the outputs. The errors are directly consulted with the reporting units. 

We apply various treatments to ensure that errors are minimised. Improvement actions include business registry updates, careful logical controls and constant contact with the reporting units.

Due to the high percentage of the population represented, the sampling error is considered negligible.

Negligible.

Information is included in the sub-concepts S.13.3.1 –S.13.3.5.

Given the high percentage of the population covered, all kinds of unit are well represented.

Over-coverage is not estimated.

 79 % come from survey. Part of taxes and network cost in percentage are taken from administrative sources.

Data are collected via electronic system. Questionnaire and reporting system provide a lot of arithmetic and logical controls between particular items that are mandatory and optional. The questionnaire cannot be submitted, if not correctly completed without any errors detected by the checking program.

Response rate is 100 %.

Unit non-response does not exist.

Item non-response does not exist.

There were no processing errors.

Not applicable.

Version 2 of the electricity price questionnaire for households for the 2nd semester of 2020 was sent 267 days after the reference period. 5 items from 142; correction of wrongly inserted numbers. 

Household electricity prices collection: 0.003045181

Non-household electricity prices collection: 0

The data come from units which sell electricity to final customers and from distributors of electricity. 

Administrative source is Regulatory Office for Network Industries.

Twice a year. 

The electronic data collection is compulsory. It is an exhaustive survey.

Data are collected by Semi-annual questionnaire on prices of electricity for final consumers.

It has been distinguished between two levels of checking:

1/ Formal checks, which are realised in the process of data entry automatically; 

2/ Informal checks aim of which is to control the complexity and relations among the variables .

According to the importance there are classified 2 basic types of informal checks:

I – informative check- this check gives the additional information, which is important for the following process of corrections. It informs also about some inconsistencies in the state of fulfilment of the questionnaire, about item non-response, exceeding stated limits etc. 

Z – check of great importance - it is mostly check indicating the exact error and it must  be always corrected or explained.

Most of the errors are directly consulted with the reporting units by our regional offices.

Amount of invoiced electricity in consumption band is the weight of supplier in calculation of national prices. The data from the regulator is merged with the results of weighted averages data coming from the survey before dissemination.

We are not doing imputations.

We are not doing adjustments.

Seasonable adjustments are not carried out.

None.
