European statistics on electricity prices for household and final non-household customers.

Internal Eurostat classification system based on annual electricity consumption bands and tax levels.

Household sector and final non-household sector (industry, services, offices, agriculture, etc).

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 disagregation 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 calculated the single national electricity prices (weighted averages for consumer bands IA-IF and DA-DE) and are published.

Some of the taxes are refundable. Here is a description of them:

Household and final non-household consumers divided into consumption bands.

Household customers: Data coming from 6 suppliers and representing 75% of the household customers.

Final non-household customers: Data coming from 6 suppliers and representing an estimated 70% of the final non-household customers.

Data for network prices comes from 4 regional network companies, representing 95% of all customers.

The price data covers the entire country of the Netherlands, but excludes the three islands part of the Caribbean Netherlands (Bonaire, Saba, St. Eustatius).

Electricity prices data for Netherlands are available since 2007.

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).

Publication calendar

Data is publicized on the open database StatLine and approachable as open data for everyone.

Electricity prices in Netherlands are published on a semestrial basis on Eurostat's website.

Electricity prices in the Netherlands are published on a quarterly basis on the open database StatLine.

The publication of the electricity prices does not include a news article or other press release.

Statistics Netherlands works together with other government bodies to publish energy prices annually. These are used for policy measures, input in climate debates, measuring household expenditures etc. Some consumption bands of electricity and natural gas prices are included.

• PBL Netherlands Environmental Assessment Agency |
• Environmental Data Compendium

The data is publicized quarterly on the Open Data portal StatLine.

Procedures applied for quality management and quality assessment are documented in the Compiler Guide.

Quality assurance at Statistics Netherlands is carried out under ISO 9001.

No formal quality assessment has been executed.

Generally, electricity prices are particularly suited for cross-country comparisons.
A key user of the electricity prices is DG ENER of the EU Commission who uses the price data for the analysis of energy prices and costs.
Another main user is the ministry of Economic Affairs and Climate (EZK), who uses the prices in their forecasts for making climate policies.

The prices per consumption band are sometimes hard to understand for users. An average price for households (and non-households) could clarify this to a certain extent.
A pattern over time of these average prices is also not possible or practical, due to varying consumption volumes within the bandwidths.

No user satisfaction consultations.

The electricity price data sets are complete.

The overall accuracy of the electricity price data with its components and sub-components can be considered to be high with the exception of the relative shares of the transmission and distribution costs which are estimated values.

Non-probability sampling is used. There are around 50 electricity suppliers in this liberated market, of which the biggest ones represented an estimated 80% of the market at the start of sampling. These are the ones that have been chosen in the sample. The costs and burden for the energy companies as well as for Statistics Netherlands were taken into account. Also, the pricing mechanisms on this liberated market lead to comparable prices for both the relatively big and small players on the market. Prices are the main reason for end-users to switch suppliers.

Information is included in the sub-concepts S.13.3.1-S.13.3.5.

No quantitative data is available to measure coverage errors.

To our knowledge over-coverage only occurs in the consumption bands DE and IA. The volumes and prices fluctuate more than should be expected within these bands, most likely caused by connections that don't qualify as end-user. An estimate of the proportion cannot be given, but the consequence of this over-coverage is that these bands are, and have been, flagged as unreliable.

The network costs for households are derived from administrative data published by network companies. They cover all the household end-users of these companies, accounting for 95% of the households in the Netherlands.

The questionnaires have built-in formulas that detect anomalies in input. The cells have conditional formatting, providing visual assistance for both the reporting companies and for us processing the data.

The level of non-response by data providers is considered to be low. We have no indication that providers would leave out data from end-users in their reporting. Non-response could occur when data seems implausible or when there are problems at the provider that cause a delay in their reporting. This is kept to a minimum.

When a band has low or no response, the price is imputed based on the price development of the nearest left available category.

Unit non-response is on average less than 1 out of 16 providers, representing far less than 5% of the target population. Non-response can vary from suppliers for households and for non-households, and can also be a regional network company.

Item non-response cannot be rated. When a data provider leaves a certain band open, it could well be that there are no end-users in that consumption band. End-users are free to switch providers at any time of the year. They can also be assigned to a higher or lower consumption band, based on an updated view on their consumed volumes. So the customer database of data providers is continuously changing.

Processing errors are assessed to be kept at a minimum. Most operations are being performed with templates and are automated. There is no quantitative information available to measure processing errors.

Not Applicable.

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.

Annual prices are coherent with the semestrial prices.

Preparation of micro data at providers level is estimated at half a day for each quarter. So in total, the 16 providers that supply micro data to Eurostat spend about 8 working days to compile and report this data.
At Statistics Netherlands, the burden is about 3 full weeks per quarter. In addition we consider one full week of additional workload per quarter due to improvements in the regular process and two full weeks per year for updating the sample.

When available and suitable, administrative sources are used. This is the case for network prices for households.

 There are no planned revisions for this statistic and there is no written policy for it.

 Unplanned revisions occur when new insights and better data cause time series to be revised. These are to be pre-announced internally and externally.

Household electricity prices collection: 0.001712538

Non-household electricity prices collection: 0.013109482

Electricity supply price data for household and final non–household consumers are collected from electricity suppliers. They use their central billing system to provide for this data.

The network costs for electricity are collected from the network companies. For households this data is retrieved from the network costs via open data that the companies publicize yearly where every household network connection is included. The network companies use their central billing system to provide us with price data for the final non-household consumers.

Quarterly

Questionnaires are collected from suppliers and network companies. Open data source from network companies, featuring tariffs per type of connection and consumption volumes per postal code are collected.

The questionnaires are in MS Excel format and can be downloaded on the webpage. There is a hyperlink called [Vragenlijst Eindverbruikersprijzen]. The companies receive a letter with username and password which they can use to upload the filled in questionnaire on this same page.

The data is validated by using the build-in validation tools of the questionnaires that are disseminated as well as several additional checks on data provided to Statistics Netherlands.

The plausibility of the input is measured in the following ways:
•    prices from the correspondents are compared to their Y-1 prices;
•    prices are compared to the prices from other correspondents in the same band;
•    prices from different bands are compared with each other, to see if there is a pattern;
•    average volumes are checked to see if data is placed in the right consumption band;
•    prices for the energy source itself are compared to current prices on the traders’ markets and to the development of relevant producer price indices.

The weighting is based on the reported consumption volumes.

An imputation method is developed whereby a consumption band with no response can still provide a price. For this, the last known price for the same period of the previous year is updated using the year-to-year trend in prices from the left nearest category.

Imputation only occurs when there is no data available in a consumption band.

Seasonable adjustments are not carried out.
