3. Statistical presentation Top
3.1. Data description

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

3.2. Classification system

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

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:

  • 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.

VAT is fully recoverable for non-households customers.

 

3.5. Statistical unit

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

3.6. Statistical population

Household customers: Data coming from 8 suppliers out of 12 and representing 100% of the household customers.

Final non-household customers: Data coming from 8 suppliers out of  12 and representing 100% of the final non-household customers.

Twice per year.

18.3. Data collection

The questionnaire is sent to statistical unit, which fill the form and sent it back to us via e-mail. The questionnaire is also on our website so the unit can download it if necessary. There are a built-in controls (logical and accounting controls) so the unit can fix an error by itself. Non-response is monitored on a regular basis and we inform the units when the deadline is approaching and ask them to fill the questionnaire and send it. We have an excel sheet like an adress book where we keep track on units which sent data.

A link to the questionnaires is: Energija | Državni zavod za statistiku (https://podaci.dzs.hr/hr/obrasci/energija/dzs.hr)
