Data are provided by all suppliers of natural gas and electricity to household and final non-household customers through a specific statisitcal survey "Electricity and natural gas prices to household and final non-household customers", included in the National Statistical Programme.

Biannual for the periods  January - June and July - December.

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  end-customers. Appropriate quantities of natural gas and electricity, delivered by each supplier are used as weights.

Not applicable.

Dataset provides prices information, comparable between countries, as prices are calculated on the base of  Eurostat's methodology for electricity/natural gas data collection (Regulation (EU) 2016/1952, Annex 1 and 2). Data are with good quality.

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.

100%

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 decisions and the tariffs for approved prices respectively of natural gas and electricity, published by EWRC - Energy and Water Regulatory Commission.

No sampling used as the data covers 100% of the population.

Not applicable.

The information is included in the following 9 indicators.

Not available. As 100% of the population (household and final non-household customers) is covered by the data, all kinds of unit are represented.

There is no over-coverage in the data.

100% of the data come from the survey.

The responding units and statistical experts are not exempted automatically from errors in entering, calculating and recording the numerical values. As the Excel questionnaire for collecting primary data and summary files are not automated, these errors are verified and corrected manually.

There are no non-responce errors.

The unit non-response rate is 0%.

The item non-response rate is 0%.

Gas/electricity price questionnaires for collecting primary data from the suppliers are Excel formatted. At national level all data is aggregated manually in Summary Excel files where national data (previously checked and verified) are calculated by formulas. For this reason no processing errors occurre. No specific tool  is used and calculations are not automated.
