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:
In the table below are the taxes reported in "All other taxes".

After arrival, the statistical office checks the micro-data for correctness, consistency and completeness and national averages are calculated and reported to Eurostat during the third month after the reference period. |
|||
14.1.1. Time lag - first result | |||
The first version of the electricity price questionnaire for households and non-households for the 1st semester of 2019 was sent 79 days after the reference period.

The first version of the electricity price questionnaire for households for the 2nd semester of 2020 was sent 88 days after the reference period. The first version of the electricity price questionnaire for non-households for the 2nd semester of 2020 was sent 85 days after the reference period.
The first version of the electricity price questionnaire for households the 1st semester of 2021 was sent 77 days after the reference period. The first version of the electricity price questionnaire for non-households the 1st semester of 2021 was sent 91 days after the reference period.

The first version of the electricity price questionnaire for non-households for the 2nd semester of 2021 was sent 89 days after the reference period. |
|||
14.1.2. Time lag - final result | |||
Final version of the electricity price questionnaire for households for the 1nd semester of 2019 was sent 274 days after the reference period, 195 days after the first version, and 182 day(s) after the mandatory deadline. Final version of the electricity price questionnaire for non-households for the 1nd semester of 2019 was sent 274 days after the reference period, 195 days after the first version and 182 day(s) after the mandatory deadline. Final version of the electricity price questionnaire for households and for non-households for the 2nd semester of 2019 was the same as first version. Final version of the electricity price questionnaire for households for the 1nd semester of 2020 was the same as first version. Final version of the electricity price questionnaire for non-households for the 1nd semester of 2020 was sent 269 days after the reference period, 182 days after the first version and 177 day(s) after the mandatory deadline. Final version of the electricity price questionnaire for households and for non-households for the 2nd semester of 2020 was the same as first version. Final version of the electricity price questionnaire for households for the 1nd semester of 2021 was the same as first version. Final version of the electricity price questionnaire for non-households for the 1nd semester of 2021 was sent 266 days after the reference period, 175 days after the first version and 174 day(s) after the mandatory deadline. Final version of the electricity price questionnaire for households and for non-households for the 2nd semester of 2021 was the same as first version.
The time lag for final results happens when a large reporting unit introduces a correction of data, which was correct from the point of view of verification algorithms. If a large unit does it, we decide to recalculate the national data and send the new version to Eurostat.
The correction of the data for the first half of the year while sending the data for the second half of the year results from the incorrect classification of end recipients in the first half of the year.
|
|||
14.2. Punctuality | |||
The legal deadline for submitting the questionnaires is the third month after the reference period. 92% of questionnaires (1st version) were delivered on time. The delay is the time between submitting the questionnaires (not exceeding the deadline) and sending it to Eurostat.
|
|||
14.2.1. Punctuality - delivery and publication | |||
The first version of the electricity price questionnaire for households and non-households for the 1st ad 2nd semester of 2019-2021 were sent on time except 2nd semester for households which was send 2 days after the deadline. The delay is the time between completion the questionnaire and sending them to Eurostat. Many providers are late sending data for various reasons. After completing all reports, we perform initial data verification. In the event of any errors, we notify the supplier who, after consultation, makes the necessary corrections. The next verification takes place after we calculate the average prices for the country, which also delays obtaining final results. It may happen that the finished final results obtained are not immediately sent to Eurostat by a person operating the edamis system, for example with a delay of 1-2 days. We will try to prevent such situations in the future. |
