This topic presents average prices of supplied electricity/natural gas to household and final non-household customers. Prices are representative for the country - data are provided by all suppliers of electricity/natural gas to household and final non-household customers for the quantities delivered through transmission/distribution network. The prices are calculated as a weighted average price by the actual supplied quantity of electricity/natural gas and their invoiced value of all end-customers.
Prices include electricity/gas basic price, transmission, distribution, excise, VAT and others.
Prices are collected and published considering three levels of taxation:
Questionnaires that cover the following areas, according to Regulation (EU) 2016/1952 of the European Parliament and of the Council on natural gas and electricity prices and repealing Directive 2008/92/EC, are provided to all data providers:
Gas and electricity prices are collected for the 2 following areas:
|Statistical concepts and definitions|
Reference customers of natural gas and electricity are characterised by the following standard annual consumption bands:
Natural gas household customers:
D1 (Small): annual consumption below 20 GJ
D2 (Medium): annual consumption between 20 and 200 GJ
D3 (Large): annual consumption above 200 GJ
Natural gas final non-household customers:
I1: annual consumption below 1 000 GJ
I2: annual consumption between 1 000 and 10 000 GJ
I3: annual consumption between 10 000 and 100 000 GJ
I4: annual consumption between 100 000 and 1 000 000 GJ
I5: annual consumption between 1 000 000 and 4 000 000 GJ
I6: annual consumption above 4 000 000 GJ
Electricity household customers:
Da (Very small): annual consumption below 1 000 kWh
Db (Small): annual consumption between 1 000 and 2 500 kWh
Dc (Medium): annual consumption between 2 500 and 5 000 kWh
Dd (Large): annual consumption between 5 000 and 15 000 kWh
De (Very large): annual consumption above 15000 kWh
Electricity final non-household customers:
Ia: annual consumption below 20 MWh
Ib: annual consumption between 20 and 500 MWh
Ic: annual consumption between 500 and 2 000 MWh
Id: annual consumption between 2 000 and 20 000 MWh
Ie: annual consumption between 20 000 and 70 000 MWh
If: annual consumption between 70 000 and 150 000 MWh
Ig: annual consumption above 150 000 MWh
Final household and non-household customers.
All final non-household (until the first semester of 2017 only end-users in the industry were observed) and household customers, meeting the criteria in Regulation (EU) 2016/1952. For natural gas: the companies using natural gas for electricity generation and non-energy use are excluded.
Prices are presented at national level. They refer to household and non-household customers doing business in Bulgaria.
From the second semester of 2007 onwards.
|Unit of measure|
Natural gas prices:
BGN/GJ (Giga Joule = one Joule x 109)
Prices over a period of six months.
Prices for first semester are average prices between January and June of each year, for second semester the prices are average prices between July and December of each year.

At national level - average price of natural gas and electricity, supplied through the network to defined groups for household and final non-household customers, according to Regulation (EU) 2016/1952.
At national level - average price of natural gas and electricity, supplied through the network to defined groups industrial end-users and households, according to Directive 2008/92/EC.
|Documentation on methodology|
Regulation (EU) 2016/1952, Annex 1 and Annex 2.
Dataset provides prices information, comparable between countries, as prices are calculated on the base of methodology for electricity/natural gas data collection (Regulation (EU) 2016/1952, Annex 1 and 2).
No information available for users of these data, as they have free access to the website of NSI.
No user satisfaction survey has been carried out for this dataset.
Data fully meet the requirements of Regulation (EU) 2016/1952 - in terms of scope, structure of consumers and price levels.
|Accuracy and reliability|
Data are reliable, the accuracy is good. Data are verified for each supplier. The comparative analysis of the data providers is made with data from previous periods and with the established prices caps for natural gas and electricity.
|Timeliness and punctuality|
Data from respondents are received one month after the reporting semester. Analysis, verification and preparation of country representative aggregate average prices are carried out by the end of the third month following the reporting period.
Data are published accurately at the date according to the Release Calendar (three months after the reporting period: for the first semester - at the end of September of the current year and for the second semester – at the end of March of the next year).
|Coherence and comparability|
|Comparability - geographical|
Data are representative at national level, as required by the methodology of calculation of prices for standard groups of household and final non-household customers (Regulation (EU) 2016/1952, Annex 1 and 2).
|Comparability - over time|

|Coherence - cross domain|
|Coherence - internal|
|Cost and burden|
|Data revision - policy|

|Data revision - practice|
Data are provided by all suppliers of natural gas and electricity to household and final non-household customers through a survey "Electricity and natural gas prices to household and final non-household customers", included in the National Statistical Programme.
|Frequency of data collection|
Exhaustive survey on average gas and electricity prices from all suppliers to final customers with electronic statistical form. Reports are received by email.
A comparative analysis of the reported data is made with the data of previous periods and with the established tariffs for price caps of natural gas and tariffs for the electricity.
Three levels of average prices in the country are estimated by standard group of users. Appropriate quantities of natural gas and electricity, delivered by each supplier are used as weights.
