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

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

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

The prices are collected in national currencies per GJ and according to different bands of consumption.

For the households sector, these bands are:

• D1: Customers consuming less than 20 GJ.
• D2: Customers consuming 20 GJ or more but less than 200 GJ.
• D3: Customers consuming 200 GJ or more.

For the final non-households sector, the bands are:

• I1: Customers consuming less than 1000 GJ.
• I2: Customers consuming 1000 GJ or more but less than 10000 GJ.
• I3: Customers consuming 10000 GJ or more but less than 100000 GJ.
• I4: Customers consuming 100000 GJ or more but less than 1000000 GJ.
• I5: Customers consuming 1000000 GJ or more but less than 4000000 GJ.
• I6: Customers consuming 4000000 GJ 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: commodity price for natural gas paid by the supplier or the price of natural gas at the point of entry into the transmission system, including, if applicable, the following end-user costs: storage costs plus costs relating to the sale of natural gas to final customers.
• 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 strategic stockpiles, capacity payments and energy security; taxes on natural gas 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.
• All other taxes: taxes, fees, levies or charges not covered by any of the previous four 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 natural gas prices (weighted averages for consumer bands I1-I6 and D1-D3) 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:

 The rate of VAT is 23% totally recoverable by nonhousehold sector

Extraordinary measures implemented in 2021: 

Application of a supplementary supply (Regulation No. 951/2021, of 2 November, of ERSE - National Regulatory Authority) whose immediate effect is felt on reported prices,

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

EURO/GJ

Household customers: Data coming from 24 suppliers representing almost 100% of the household customers.

Final non-household customers: Data coming from 28 suppliers representing almost 100% of the final non-household customers.

Whole country including Açores and Madeira islands

Natural gas prices data for Portugal are available since 2002.

Not applicable.

Prices are reported in national currency per GJ. However, Eurostat also calculates and publishes the prices in EURO and PPS (purchasing power parity) and do the conversion to kWh.
Relative shares of sub-component of the network component (transmission and distribution) and consumption volumes are reported in percentages.

For semestral 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).

The exercise of these competences by DGEG is performed under Statistics Portugal technical-scientific and methodological supervision and with strict compliance with the legislation and rules issued by the National and European Statistical System. Within this functions delegation, DGEG adopted the European Statistics Code of Practice and the Statistics Portugal Confidentiality Charter as well as other Statistics Portugal policies such as Dissemination and Revision policies in particular.

All statistical production by DGEG is based on administrative data available in the area of energy and geological resources, which are collected in the exercise of its competences. DGEG defines the content, form and timing of dissemination of information.

DGEG ensure the equal access to all users and there is no priority entity receiving (previously) information.

Natural gas prices in Portugal are published on a semestrial basis on Eurostat's website, and webpage DGEG.

All statistical information is released in DGEG webpage (www.dgeg.gov.pt in the menu: Statistics - Energy - Energy Prices- Elecricity and  Natural Gas Prices).

Natural Gas prices (UE-27) are published after the publication of Eurostat (semestrial basis).

The data is also published in EIA (quarterly).

We only published on the webpage of DGEG.

In addition to the semestral publication, DGEG has an annual publication that aggregates the most relevant data on the energy sector in Portugal produced by DGEG, as well as other data systematized by ADENE, including natural gas prices.

The energy statistics (data and work applications) are allocated in excel files and documents, previously created according to the respective methodologies to be applied to each type of statistical operation.

Not applicable

We don't give access to microdata.

No other ways for disseminating the data.

Not applicable

DGEG prepares (and updates) written methodological documents for each delegated statistical operation, based on standard methodological documents defined according to the National Statistical System. These documents present a detailed description of the statistical methodology (transmission, treatment, analysis and dissemination of data), applied regulation and legislation, concepts, definitions and classifications of each statistical operation. All documents, after approval by Statistics Portugal, are published on our webpage (DGEG).

Not applicable

The availability of all quality related documents is according with the National Statistical System Law and the protocol signed with Statistics Portugal.

However, we don´t have specific quality documents available.

Within the framework of its competences and according with the National Statistical System Law and the protocol signed with Statistics Portugal, DGEG regulates itself, by quality standards on the statistical data produced and a  Quality Commitment Statement is under approval.

Strength: Statistical production is of responsibility of a specific and independent department in DGEG, which guaranties higher specialization and a focus on statistical matters and professional independence.

Weakness: Short budget to develop specific surveys on energy creates problems on the implementation of improvements.

The Users of the data include Governament, ERSE (National Regulatory Authority), operators, energy stakeholders, media/Press, embassies, universities, customers and general population.

Regarding the use that entities make of statistics, for example the government uses for political decisions, ERSE for Price and consumption analysis and tariff implications, the Companies for price comparison and analysis;

Regarding energy stakeholders, media/Press, embassies, universities, customers and general population for analysis and evolution of gas market.

The main products analyzed are the prices and the associated taxes and fees.

Users only have access to information published by DGEG.

DGEG does not have any specific satisfaction survey to the users of statistical information.

The dataset transmitted to Eurostat comply with the Regulation 2016/1952.

Portugal uses the Eurostat template and receive the information by email.

All steps in the production of statistics are analysed in relation to coherence and consistency mainly through the identification of breaks in a time series or the analysis of geographic scope and refrence period.

If any outlier is detected the provider of the information is required to provide clarifications/justifications to explain the situation.

The production of the Statistics of the Prices related to Natural Gas and Electricity is therefore the result of the use of information of an administrative date, which has historically been in the possession of the DGEG in the scope of its competences, at national level, european and international representation, to produce information on the energy and geology.

The statistical operation applies to natural gas and electricity trading companies located in Portugal and active in the reference period.

The information obtained is covered by validation rules (such as coherence and consistency) and for this purpose there are templates in excel sent by Eurostat, gathering the information obligations of the operators.

The fulfillment of the data follows a specific structure. DGEG when receiving the information compiles the data that once loaded is manually validated. In case of errors the responsible entity is contacted.

The data sent (semester) is compared with the previous period.
