External users are the Ministry of Petroleum and Energy, IEA and Eurostat.

Internal users of the statistics: the Division for energy and environmental statistics, which uses the data in the energy balance and the energy account; the Division for manufacturing, which uses some of the data in the monthly Index of production. The statistics are also used by the Division for national accounts.

Electricity annual

External users are the Ministry of Petroleum and Energy, the Ministry of Finance, Norwegian Water Resources and Energy Directorate, Enova, the International Energy Agency (IEA) and Eurostat. The Annual electricity statistics are important input to the Energy balance and energy account. The data material is also used by the Divison for National Accounts (930) and Divison Industrial Production Statistics in Statistics Norway.

Electricity monthly and electricity annual

No external users have access to the statistics and analyses before they are published and accessible simultaneously for all users on ssb.no at 8 am. Prior to this, a minimum of three months' advance notice is given in the Statistics Release Calendar.

For more information, see Principles for equal treatment of users in releasing statistics and analyses

Electricity monthly

The monthly statistics are used in the revision of the annual electricity statistics. The two statistics correspond well.

Electricity annual

Monthly and annual electricity statistics correspond well.

Tables showing electricity prices in the wholesale market and the end-user market are available in the annual electricity statistics and quarterly electricity price statistics. The quarterly electricity price statistics are based on a sample of about 40 enterprises in the wholesale and end-user market, and are released around two months after the end of the quarter. Annual electricity statistics include all the enterprises in the population, and are released about 12 months after the reference year.   

The quarterly electricity price statistics have the most up-to-date electricity prices and provide information about different types of price contracts (spot price, variable price and fixed price). The annual electricity statistics are more detailed and the data source covers the whole population.

The population consists of all water, thermal and wind power stations (Standard for sector classification 2007: 35.11). Electricity consumption in extraction of crude petroleum and natural gas includes all land-based electricity consumption and consumption on offshore installations connected to land by power cable (Standard for sector classification 2007: 06.1 and 06.2).

Electricity consumption in power-intensive manufacturing based on the standard for sector classification 2007  includes:

17.1 – Pulp and paper production

20.1 – Production of chemical commodity

24.1 – Production of iron, steel and ferroalloy

24.4 – Production of aluminium and other metals

Electricity annual

The enterprise is the statistical unit.

The Electricity statistics contain all electricity plants that have a license for electricity generation, transmission and distribution in addition to trade of electricity.

The Electricity statistics do not contain:

* Production plants having rated output less than 100 kW

* Power stations which although partly owned by Norwegian interests are located outside Norwegian territory

* Electricity production and consumption on offshore installations not connected to land by power cable

* Main office activities in own enterprises

Electricity monthly

Statistics Norway receives a dataset from Elhub about six days after the reference month containing data on production and consumption of electricity from all metering points in Norway. Elhub is an electricity data hub which is a centralized information exchange system for the electricity retail market and contains data on consumption and production of electricity and different market processes from all remotely (and traditional) readable electricity metering points in Norway. From the dataset Statistics Norway calculate electricity production, pump storage, and consumption of electricity in power intensive manufacturing and extraction which is used in the monthly electricity statistics.
Data on import and export of electricity is collected from Statnett and electricity production on Svalbard is collected by Statistics Norway in an own survey.

Production of electricity:
Total count of all power plants in Norway.

Consumption:
Extraction of crude petroleum and natural gas consists of approximately 10 establishments (approximately a total count).
Power-intensive manufacturing consists of approximately 50 establishments (approximately a total count).

Electricity annual

Data collection together with Norwegian Water Resources and Energy Directorate.

Total Count.

Electricity monthly

Statistics Norway receives a dataset from Elhub with measured values for production and consumption of electricity for all metering points in Norway. Since Svalbard is not included in the Elhub data, electricity data from Svalbard is collected in an own survey. Electricity import and export are reported by Statnett once per month.

Data from the Elhub system is used by electricity producers and suppliers and distribution network companies serving electricity consumers and balancing electricity production, hence the metering values is thoroughly checked before Statistics Norway receives the data. Still, we do some checks on production and consumption codes, aggregated values for production and consumption and duplicates in the data. Data are also compared with the yearly electricity statistics.

Electricity annual

As of 2000, the electricity utilities have reported their data electronically via the system ERAPP.

• Income statements and balance sheets are controlled by auditors
• The annual reports of the enterprises are useful in the revision of data
• Values that are particularly low or high are double checked by contacting the enterprise
• The power balance is controlled in detail
• Power sale to different consumer groups should be in line with the Standard Industrial classification of 2002.

Among other things, maximum and minimum values in addition to percentage changes are calculated

In some municipalities and counties a few units may account for a large share of the electricity production and consumption. However, these figures are not considered to be particularly detrimental for the relevant enterprises.

The statistics are comparable back to 1979. However, prior to 1993 the information is less detailed than in later releases.

Until December 2010, pulp and paper production and extraction of crude petroleum and natural gas were included in consumption without power-intensive manufacturing. As from the release in January 2011 these groups are separated into their own consumption groups. Only total consumption in power-intensive manufacturing , non-priority and priority consumption in power-intensive manufacturing and consumption without power-intensive manufacturing and extraction are affected by the changes. The rest of the groups are not influenced by the change.

From January 2016, the basis for calculating net loss was changed from utilising loss shares of the Norwegian Water Resources and Energy Directorate to loss shares calculated from net loss reported in the annual electricity statistics. This affects the series net loss, net consumption of electric power and consumption without power-intensive manufacturing and extraction somewhat. The new way of calculating net loss ensures a closer correspondence between the monthly and the annual electricity statistics. All series in Statbank are updated dating back to January 2010

In May 2019 the name of the variable “Pump storage use and other own consumption” was changed to “Pump storage use” since “other own consumption” no longer is included in this variable. Because of this change, the old variable “Pump storage use and other own consumption” and new variable “Pump storage use” cannot be compared directly.

As from the release of the monthly electricity statistics of May 2019 Elhub has been utilised as datasource for electricity generation and pump storage consumption. The change does not have an impact on the time series of production and pump storage. 

As from the release of the monthly electricity statistics of October 2019 Elhub has been utilised as datasource for consumption in extraction of crude petroleum and natural gas. The change does not have an impact on the time series of extraction of crude petroleum and natural gas.

As from the release of the monthly electricity statistics of January 2020 Elhub has been utilised as datasource for consumption in power intensive manufacturing. The change does not have an impact on the time series of pulp and paper production, production of chemical commodity etc., production of iron, steel and ferroalloy and production of aluminium and other metals.

In the electricity statistics of 2008 the sale to different end users is based on a new version of Norwegian industry classification (SIC2007) . The most important changes are:

• The numbers of end users increase from 27 to 36 categories.
• Power intensive manufacturing now also includes industry 17.1.
• For the first time we also calculate a grid rent for power intensive manufacturing. Since power intensive manufacturing has a very low grid rent compared to other end users, total grid rent for all end users is not comparable with former years.
• We do not publish gross value of production, intermediate consumption and value added at factor prices in the electricity statistics of 2008. Instead of these variables we publish production value, cost of goods and services consumed and value added.

The enterprise is the statistical unit. Prior to 1993 the establishment was the unit, defined as all energy activities located in one distribution area. This change concerns only utilities with activities in several distribution areas and it only affects the total count of electricity utilities.
