Dutch energy balance sheet

What does the survey comprise?

Purpose

Providing insight into the energy flows in the Netherlands. The Dutch energy balance sheet consist on the one hand of indigenous production, imports and exports and stock change and on the other hand of energy consumption.

Target population

Companies based in the Netherlands that process, store or trade energy commodities, households and transport.

Statistical unit

Statistics Netherlands has a general business register (ABR) describing the Dutch business population as statistical units. The statistical units Enterprise, Enterprise Group and Local Unit are derived from this register. The register forms the basis for the definition of the population and the sampling of many business statistics, including the energy statistics. 

Date/year survey started

Some key figures are available from 1946 onwards. The complete energy balance sheet broken down by many energy commodities and sector of industry is available from 1995 onwards.

Frequency

Annual.

Publication strategy

Energy balance sheet; supply, transformation and consumption
Annual figures
• Revised provisional figures: June/July of the second following year
• Definite figures: November/December of the second following year

With the publication of revised provisional annual figures the underlying monthly balance sheets retain their provisional character. There are monthly balance sheets of energy commodities natural gas, hard coal, electricity, petroleum products, crude and motor fuels. Upon publication of the definite annual energy balance sheet the monthly balance sheets will be definite.

Energy balance sheet; key figures

Annual figures:

• Provisional figures: March/April of the following year

• Revised provisional figures: June/July of the following year

• Definite figures: November/December of the following year

How is the survey conducted

Survey type

The informants are the energy companies and energy consumers in all sample sizes 0 to 9. We require a balance sheet of energy commodities.  Furthermore we use registrations.

Survey method

The survey is conducted through questionnaires that can be completed online:
• Indigenous production, transformation and consumption of energy, extensive monthly questionnaire
• Indigenous production, transformation and consumption of energy, extensive quarterly questionnaire
• Indigenous production, transformation and consumption of energy, brief quarterly questionnaire
• Consumption of Energy, brief annual questionnaire
• Crude and petroleum products, extensive monthly questionnaires
• Indigenous production, production and consumption of renewable energy, monthly and annual questionnaires

In addition registrations are used (with aggregated figures) that are derived from:
• TenneT: imports and exports of electricity
• TNO: indigenous production of crude oil and natural gas
• GasUnie Transport Services (GTS): indigenous production, imports and exports of natural gas
• Zebra: imports of natural gas
• Energie-Nederland: district heating

• Regional energy companies 
• Statistics Netherlands -International trade: imports and exports of energy commodities

Respondents

In the Netherlands based companies, that process, store or trade energy commodities, households and transport.

Sample size

The sample consists of about 4,000 companies.

Checking and correction methods

- For each respondent the energy balance must be balanced. At national level the difference betwee supply and consumption should be not too large.
- The opening stock of the current period must be equal to the closing stock of the last period.
- Individual and aggregated figures get a plausibility check. This is done by comparing the previous period with the corresponding periods of previous years.
 - Imports and exports are compared to the international trade statistics.

Weighting

Not applicable.

Quality of the results?

Accuracy

In the energy balance sheet all energy commodities are published in petajoules (PJ). Petajoule is an unit for energy. This equals 1,000,000,000,000,000 joules (10 to the power 15). A joule is a unit of energy equivalent to 0.24 calories. A PJ is equivalent to 31.6 million cubic meters of natural gas or 278 million kilowatt-hours of electricity.

Sequential comparability

The figures are comparable in terms of definitions. In addition to the publication of the figures, the change in the classification of the different sectors, respectively SIC93 and SIC2008, are taken into account.

Revisions

In 2015 the figures of the energy balance sheet have been revised for 1995 up to and including 2013. The main reasons for this were a break in the time series for the sector petrochemicals, the possibility to use connection records of the enrgy companies to determine the final consumption of natural gas and electricty and the availability of new sources of information of the consumption of fuels for transport and mobile sources. Furthermore, a number of changes of smaller size, such as correcting errors found and adjustment of figures by the availability of new information.  See for more information Revisie energiebalans 1995-2013, in Dutch only.

Quality strategy

- All completed forms are checked. Any questions are discussed with the respondent.
- Where possible, results are compared with other figures of Statistics Netherlands, e.g. the international trade statistics.
- Statistics Netherlands follows the international energy statistics quality guidelines (see the Energy Statistics Manual by International Energy Agency (IEA) and Eurostat).
