Reference metadata describe statistical concepts and methodologies used for the collection and generation of data. They provide information on data quality and, since they are strongly content-oriented, assist users in interpreting the data. Reference metadata, unlike structural metadata, can be decoupled from the data.

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 disaggregation 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 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.
In Malta, the VAT and the excise duties are not refundable.
Currently there are no subsidy schemes in place on taxes for the customers.
3.5. Statistical unit
Household and final non-household consumers divided into consumption bands.
3.6. Statistical population
Household customers: Data coming from two administrative sources and representing 100% of the household customers.
Final non-household customers: Data coming from two administrative sources and representing 100% of the final non-household customers.
3.7. Reference area
MALTA (MT)
3.8. Coverage - Time
Electricity prices data for Malta are available since 1991.
3.9. Base period
Not applicable.
Prices are reported in national currency per kWh. However, Eurostat also calculates and publishes the prices in EURO and PPS (purchasing power parity). Relative shares of sub-component of the network component and consumption volumes are reported in percentages.
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).

7.1. Confidentiality - policy
At EU level:
Regulation (EC) No 223/2009 of the European Parliament and of the Council, of 11 March 2009, on the transmission of data subject to statistical confidentiality to the Statistical Office of the European Communities.
At national level:
The NSO requests information for the compilation of official statistics according to the articles of the MSA Act – Cap. 422 and the Data Protection Act – Cap. 586 of the Laws of Malta implementing the General Data Protection Regulations (GDPR).
Article 40 of the MSA Act stipulates the restrictions on the use of information while Article 41 stipulates the prohibition of disclosure of information. Furthermore, Section IX of the Act (Offences and Penalties) lays down the measures to be taken in case of unlawful exercise of any officer of statistics regarding confidentiality of data.
Since its inception, the NSO has always assured that all data collected remains confidential and that it is used for statistical purposes only according to the articles and derogations stipulated in the laws quoted above. The Office is obliged to protect the identity of data providers and refrain from divulging any data to third parties that might lead to the identification of persons or entities.
During 2009, the NSO has set up a Statistical Disclosure Committee to ensure that statistical confidentiality is observed, especially when requests for microdata are received.
Upon employment, all NSO employees are informed of the rules and duties pertaining to confidential information and its treatment. In line with stipulations of the MSA Act, before commencing work, every employee is required to take an oath of secrecy whose text is included in the same Act.
An internal policy on anonymisation and pseudo-anonymisation is in place to ascertain that adequate methods are used for the protection of data which the office collects and shares with the public in its capacity as the National Statistics Office. The policy is meant to safeguard confidentiality of both personal and business data entrusted to the NSO. The document provides guidance for all NSO employees who process data on a daily basis as to how anonymisation and pseudo-anonymisation methods should be applied. The policy applies to all confidential, restricted and internal information, regardless of form (paper or electronic documents, applications and databases) that is received, processed, stored and disseminated by the NSO.
7.2. Confidentiality - data treatment

10.6.1. Metadata completeness - rate
Not applicable.
10.7. Quality management - documentation
The NSO has developed an internal Quality Management Framework (QMF) which is built on common requirements of the ESS Code of Practice (ESS CoP). A document was prepared to include a set of general quality guidelines spanning over all statistical domains. Assuring methodological soundness is an integral part of the QMF, nonetheless, the document spans also on other areas related to institutional aspects.
11.1. Quality assurance
The quality assurance procedures detailed in Eurostat’s Compilers guide on European Statistics on natural gas and electricity prices have been applied.
11.2. Quality management - assessment
The quality of the data is very good due to absence of errors. The data will be already checked once we receive it from the sources. Then the NSO does further checking and any discrepancies found from past data are verified with the sources.
The data sources conducts its own quality assessments, however, the NSO verifies the data submitted by the sources for implausible combinations, consistency across time, data gaps and coherence. Such consistency checks ensure that the overall quality of the data is good.
12.1. Relevance - User Needs
On a national level, electricity prices data are not published. This data is only sent to Eurostat on a semestrial basis.
12.2. Relevance - User Satisfaction
Not available.
12.3. Completeness
The only table that is not filled is table 3. Figures for table 3 are not available and thus they are flagged as ‘O’. The reason behind it is that currently there is no distinction in the network costs between the transmission costs and the distribution costs. Thus, percentages cannot be calculated. Refer to section 18.5 for further information on the other tables.
12.3.1. Data completeness - rate
Only 4 data points are not reported out of 148. These 4 refer to the figures in table 3 for household and non-household which are not available.
13.1. Accuracy - overall
Due to absence of errors, the accuracy of the data is considered very good.
13.2. Sampling error
There are no sampling errors as sampling is not performed in this data collection as 100% of the population is represented.
13.2.1. Sampling error - indicators
There are no sampling errors as sampling is not performed in this data collection as 100% of the population is represented.
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
There are no coverage errors as sampling is not performed in this data collection as 100% of the population is represented.
13.3.1.1. Over-coverage - rate
There is no over-coverage.
13.3.1.2. Common units - proportion
All data is coming from two administrative sources.
13.3.2. Measurement error
Once NSO receives electricity prices data from the sources, it covers 100% of the population. The task of the NSO is that of comparing prices with previous years data and check for any discrepancies.
13.3.3. Non response error
There is no non-response error.
13.3.3.1. Unit non-response - rate
Sampling is not performed in this data collection and thus 100% of the population is covered. Our data sources provide the administrative data required to complete the questionnaire. There is no unit non-response error.
13.3.3.2. Item non-response - rate
The only figures that are not provided are those in table 3 which are not available from the sources.
13.3.4. Processing error
Once NSO receives electricity prices data from the sources, it assumes that it has no issues with regards to processing errors. The task of the NSO is that of comparing prices with previous years data and check for any discrepancies.
13.3.5. Model assumption error
Not Applicable.
14.1. Timeliness
The administrative data sources are requested to provide the electricity price data within two/three 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 2022 was sent 91 days after the reference period.
The first version of the electricity price questionnaire for households for the 2nd semester of 2022 was sent 82 days after the reference period.
The first version of the electricity price questionnaire for households for the 1st semester of 2023 was sent 90 days after the reference period.
The first version of the electricity price questionnaire for households for the 2nd semester of 2023 was sent 86 days after the reference period.
The first version of the electricity price questionnaire for households for the 1st semester of 2024 was sent 93 days after the reference period.
The first version of the electricity price questionnaire for households for the 2nd semester of 2024 was sent 86 days after the reference period.
The first version of the electricity price questionnaire for non-households for the 1st semester of 2022 was sent 91 days after the reference period.
The first version of the electricity price questionnaire for non-households for the 2nd semester of 2022 was sent 82 days after the reference period.
The first version of the electricity price questionnaire for non-households for the 1st semester of 2023 was sent 90 days after the reference period.
The first version of the electricity price questionnaire for non-households for the 2nd semester of 2023 was sent 86 days after the reference period.
The first version of the electricity price questionnaire for non-households for the 1st semester of 2024 was sent 93 days after the reference period.
The first version of the electricity price questionnaire for non-households for the 2nd semester of 2024 was sent 86 days after the reference period.
14.1.2. Time lag - final result
When NSO transmits the questionnaire for semester 2, a revised version of semester 1 is provided as well. The reason behind this is that the data up until NSO provides semester 1, does not capture all the units used. Also, when NSO transmits semester 1 of the following year, a revised version of semester 2 of the previous year is also transmitted.
Although in the revised submissions updates were made, there was no break in series.
14.2. Punctuality
The legal deadline for submitting the questionnaires is the third month after the reference period.
Data was transmitted to Eurostat on time in our recent submissions.
14.2.1. Punctuality - delivery and publication
Questionnaires were submitted according to their legal deadline.
15.1. Comparability - geographical
In order to ensure comparability across all Member States, the definitions for electricity prices as stipulated in the Regulation (EU) 2016/1952 of the European Parliament and of the council of 26 October 2013 on European statistics on natural gas and electricity prices and repealing Directive 2008/92/EC were strictly adhered to. In addition, attention was devoted to the reporting of variables to ensure utmost adherence to the established criteria, specifications and regulations.
It should be noted that since in Malta there are only the Value Added Tax and the excise duties, comparisons cannot be made with other Member states for the remaining taxes.
15.1.1. Asymmetry for mirror flow statistics - coefficient
Not applicable.
15.2. Comparability - over time
To ensure comparability with previously reported data, the NSI deemed as important to extract data from a well-established data sources which were also utilised for previous data reporting exercises. The only difference from Semester 1 of the year 2017 onwards is that of the excise duties. In previous submissions the excise tax was aggregated with the total electricity prices. In recent submissions, the excise tax was removed from the variable All taxes excluded in table 1 and in table 2 and was listed under the variable Environmental taxes. Although in the revised submissions updates were made, there was no break in series.
15.2.1. Length of comparable time series
The length of the time series is from 1991 to 2024.
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
For Malta, annual prices are coherent with the semestrial prices.
Since the data covers 100% of the population, the administrative sources have to compile electricity prices on data that is collected throughout the year up to the extraction date. That is why when the NSO submits figures for one semester, revisions are made on the previous semester, because more collection of data is done by that time.
17.1. Data revision - policy
Revision of data compliant with the ESS Code of Practice principles.
The NSO has established a Revisions of Official Statistics Policy governing revisions that occur for all statistics produced across all statistical domains. This policy outlines the general principles and procedures followed by the NSO for any revisions of data and are meant for both users and producers of statistics to gain a better understanding of the revision process and its analysis.
17.2. Data revision - practice
Semester 1 data are revised when submitting the semester 2 data for consistency reason between semestrial and annual prices.
17.2.1. Data revision - average size
Revisions were sent as outlined in section 14.1.2.
18.1. Source data
Electricity Prices
The sources for electricity prices data are ARMS and Enemalta plc which provide us with billing data. From ARMS and Enemalta, NSO receives administrative data which is used to compile the submissions sent to Eurostat on a semestrial basis.
Network Costs
The source for the network costs is the Enemalta plc which is the energy services provider in Malta. Each year, NSO receives the amount for the network costs for that particular year.
18.2. Frequency of data collection
NSO collects data from ARMS and Enemalta plc, a month prior to submitting the corresponding semester to Eurostat.
18.3. Data collection
NSO requests administrative data from ARMS and Enemalta plc. It provides electricity prices disaggregated by the corresponding consumption band.
18.4. Data validation
The administrative sources have validation rules in place and also experts who analyse the data further in cases where there are discrepancies in the data from one year to another.
18.5. Data compilation
NSO requests data from ARMS and Enemalta plc, for the semester that is required to send to Eurostat. In the administrative data, the following variables are provided: (i) the amount of units used in Malta, (ii) the sum of charge for these amounts and (iii) the price per kWh. This data is disaggregated by each consumption band. The sources provide such figures for the Residential, Domestic and Non-Residential which comply with the definitions used by other countries.
Once this data is received, some checks are undertaken even though it would have already been validated by the sources. The data is compared with the previous two semesters to check if there are any major changes in any of the bands. For all the found inconsistencies, NSO queries the sources to obtain the reasoning behind these changes from one semester to another.
For the electricity price questionnaire for households, NSO uses the figures for the Residential and the Domestic. In table 1 for the variable ‘All taxes excluded’ the excise tax is removed from the sum of charge to obtain the electricity prices. The excise tax is the only tax included in the sum of charge that needs to be obtained separately. In Malta, the excise tax is of €1.50 per MWh. In the variable ‘VAT excluded’ the excise tax is included but the VAT is not added. In the final variable ‘All taxes + VAT included’, the VAT is added to the figures in the variable ‘VAT excluded’.
In table 2 a disaggregation of the taxes is provided. This table is only sent in Semester 2. Enemalta plc provides the network costs for the corresponding year. First, the VAT is calculated, which is now calculated on averages of the whole calendar year. The excise tax in Malta is of €1.50 per MWh and falls under the variable ‘Environmental taxes’. Then the variable ‘Energy and supply’ is the amount when the network costs, the VAT and the Environmental taxes are subtracted. Currently there are no subsidy schemes in place on taxes for the customers.
Figures for table 3 are not available and thus they are flagged as ‘O’.
In table 4 the consumption volumes (%) for each consumption band are provided. Again, this table is only sent in Semester 2. The sum of units obtained from the administrative sources are used to calculate such percentages.
When NSO transmits the questionnaire for semester 2, a revised version of semester 1 is provided as well. The reason behind this is that the data up until NSO provides semester 1, does not capture all the units used. Also, when NSO transmits semester 1 of the following year, a revised version of semester 2 of the previous year is also transmitted.
The same procedure is followed for the electricity price questionnaire for non-households. In this case, the administrative data corresponding to the Non-Residential is used.
18.5.1. Imputation - rate
All the figures submitted to Eurostat were not imputed since administrative data is used.
18.6. Adjustment
Not applicable.
18.6.1. Seasonal adjustment
Seasonable adjustments are not carried out.

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 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.
In Malta, the VAT and the excise duties are not refundable.
Currently there are no subsidy schemes in place on taxes for the customers.
Household and final non-household consumers divided into consumption bands.
Household customers: Data coming from two administrative sources and representing 100% of the household customers.
Final non-household customers: Data coming from two administrative sources and representing 100% of the final non-household customers.
