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 disaggregation 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 calculate 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:

Prices are reported in national currency per kWh. However, Eurostat also calculates and publishes the prices in EURO and PPS (purchasing power parity). |
|
|||
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). |

11.1. Quality assurance | |||
The quality of the data has been assessed through several self-assessments by the statistics team on a regular basis and corrections made when required. |
|||
11.2. Quality management - assessment | |||
The electricity price survey captures most of the retail market (98% of households, 96% for non-households). All large electricity suppliers respond. The data collection for Table 1 has been carried out since 2007 and so survey respondents are very familiar with the requirements and procedures have been put in place to extract the data twice a year. There are also in-house checks and so we can be assured of the quality of the data collected for Table 1. The data collection for the main components in Table 2 has also been carried out since 2007 and here again we are confident of the quality of the data. The sub-components in Table 2 and data in Table 3 were introduced in 2018. The data are of good quality, however suppliers may be asked to revise their data to ensure the value of the components falls between the two semesters. Consumption data in Table 4 has been collected since 2007 and can be verified against administrative data published by Ireland's energy regulator. |
|
|||
12.1. Relevance - User Needs | |||
Stakeholders include the Ministry, suppliers, energy regulator and associations. Weighted average natural gas prices feed into national measures of energy cost competitiveness. These were developed out of an action in the 2015 Energy White Paper to ensure policy choices are evidence-based with a focus on competitiveness, security and sustainability. Eurostat now publish consumption shares by band for each country, allowing the calculation of a single price per country. However, a single weighted average EU price calculated and published by Eurostat would also be of interest. Other users include the general public, particularly for household prices and this is often picked up by the media. |
|||
12.2. Relevance - User Satisfaction | |||
User views and opinions are not currently formally collected. These data are used as part of a model to forecast prices The Department of the Environment, Climate and Communications and other government agencies regularly request and use the price data. Comments and feedback are noted. |
|||
12.3. Completeness | |||
The electricity price data sets are complete. |
|||
12.3.1. Data completeness - rate | |||

No precision measures available. |
|||
13.3. Non-sampling error | |||
Information is included in the sub-concepts S.13.3.1-S.13.3.5. |
|||
13.3.1. Coverage error | |||
The market coverage for the household sector (all units) is greater than 90%. The market coverage for the final non-household sector is 100%, but customers that buy electricity from the wholesale market are excluded in this survey. |
|||
13.3.1.1. Over-coverage - rate | |||
Not aware of any over-coverage in the data. |
|||
13.3.1.2. Common units - proportion | |||
100% of the data comes from a survey. |

Not Applicable. |
|
|||
14.1. Timeliness | |||
Electricity providers that participate in the national data collection are requested to provide the electricity price data within 2 months after the reference period. 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 for the 1st semester of 2019 was sent 92 days after the reference period. The first version of the electricity price questionnaire for households for the 2nd semester of 2019 was sent 91 days after the reference period.

[Number of days should be entered and comments provided if questionnaire was never sent] |
|||
14.1.2. Time lag - final result | |||
Version 2 of the electricity price questionnaire for non-households for the 1st semester of 2021 was sent 100 days after the reference period, 11 days after the first version and 8 day(s) after the mandatory deadline. The first version of the questionnaire had been uploaded to eDamis with incorrect codes.
Version 2 of the electricity price questionnaire for non-households for the 2nd semester of 2021 was sent 91 days after the reference period, 1 days after the first version and 1 day(s) after the mandatory deadline. Data was revised for Table 2 after discussions with Eurostat |
|||
14.2. Punctuality | |||
The legal deadline for submitting the questionnaires is the third month after the reference period. Some data suppliers do not submit in time for the deadline. We are working to put agreements in place to prevent this from happening in the future. In case an electricity supplier does not provide the data on time, the national averages are still calculated and reported to Eurostat within the deadline of 3 months, but the data will be flagged with an appropriate flag. Once the micro data is complete, the final prices are reported to Eurostat without the flag. |
|||
14.2.1. Punctuality - delivery and publication | |||
Supplier survey responses may be late due to the following reasons:
|
|
|||
15.1. Comparability - geographical | |||
Data is comparable between regions. |
|||
15.1.1. Asymmetry for mirror flow statistics - coefficient | |||
Not applicable |
|||
15.2. Comparability - over time | |||
Electricity prices can be directly compared over time. |
|||
15.2.1. Length of comparable time series | |||
Data is comparable from 2007. |
|||
15.3. Coherence - cross domain | |||
Not applicable |
|||
15.3.1. Coherence - sub annual and annual statistics | |||
Not applicable |
|||
15.3.2. Coherence - National Accounts | |||
Not applicable |
|||
15.4. Coherence - internal | |||
Annual prices are coherent with the semestrial prices. |
|
|||
The response burden is significant for electricity providers, in particular the more detailed sub-component breakdown introduced under Regulation (EU) 2016/1952. No further details on respondent burden are currently available. Only data required for under Regulation (EU) 2016/1952 is collected. Administrative data is not available and so suppliers must be surveyed directly. In the case of some suppliers this data is not readily available from their accounts. Best estimates are accepted when exact details are not available. At our institute, the burden is about 5 person days for data collection in total covering households and non-households for each semester. |
|
|||
17.1. Data revision - policy | |||
Data may be revised if a supplier submits data after the deadline or revises historic data. If possible, Eurostat are informed of these revisions and pre-announcements are made. |
|||
17.2. Data revision - practice | |||
Provisional data might be sent to Eurostat in case not all electricity suppliers have sent their micro data. |
|||
17.2.1. Data revision - average size | |||
Version 2 of the electricity price questionnaire for non-households for the 1st semester of 2019 was sent 275 days after the reference period. Version 2 of the electricity price questionnaire for non-households for the 1st semester of 2019 was sent 299 days after the reference period. These questionnaires were revised after errors were found in the data and suppliers were asked to resubmit. Household electricity prices collection: 0.005227664 Non-household electricity prices collection: 0.034202952 |
|
|||
18.1. Source data | |||
Electricity price data for household and final non–household consumers are collected from electricity suppliers. The suppliers use their central billing system to extract average price data for each consumption band components and sub-components as well as relative consumption figures. |
|||
18.2. Frequency of data collection | |||
Electricity prices for household and final non-household consumers are collected from electricity suppliers every 6 months. |
|||
18.3. Data collection | |||
The electricity price data is reported by the electricity suppliers from Ireland by using excel based, dedicated questionnaires. Returns are made by email. Please see sample questionnaire in the annexes. Annexes: Electricity Supplier Survey |
|||
18.4. Data validation | |||
Before sending the questionnaires to Eurostat, the data is validated by using in-house checks and the built-in validation tools of the Eurostat questionnaires, as well as by visual inspection for completeness. In-house checks include comparing with previous semester returns for price and volume and relative deviation between suppliers. Values outside reasonable limits are queried back to the supplier(s). |
|||
18.5. Data compilation | |||
For household and non-household consumers, the calculation of the national average prices is weighted by using the individual consumption figures for each electricity supplier in each consumption band. |
