About the statistics

The statistics include production, power exchange and consumption. The monthly electricity statistics should be used when the latest data is needed. The annual figures have more detailed information and also include electricity prices, profit and loss accounts and investments.

Definitions

Definitions of the main concepts and variables

Electricity monthly

Total production of electricity

Electricity generation contains net production. Consumption related to pump storage and industrial processes should be reported separately and is included in the net production.

Exports of electric power

Exports of electric power is power produced in Norway that crosses the Norwegian border.

Imports of electric power

Imports of electric power is power produced abroad that crosses the Norwegian border.

Gross consumption of electricity

Gross consumption of electricity is the sum of gross production of electricity and imports less exports of power.

Pump consumption

Pump consumption is power used to run pump stations that elevate water from a lower to higher level.

Calculated net loss

Net loss is calculated using a fixed loss share relative to production based on net loss reported in the annual electricity statistics. The loss share is calculated using a five year average and is 6 per cent in 2016. The net loss partly depends on distance, temperatures and the quality of the grid.

Net consumption of electric power

Net consumption of electric power is gross consumption of electric power less pump consumption, other own consumption and calculated net loss.

Consumption of electric power in extraction of crude petroleum and natural gas production

Electricity consumption in extraction of crude petroleum and natural gas consists of all land-based electricity consumption and consumption on offshore installations connected to land by power cable.

Total consumption in power-intensive manufacturing

Total consumption in power-intensive manufacturing is the sum of flexible and ordinary consumption in power-intensive manufacturing. Power-intensive manufacturing is defined as pulp and paper production, industrial chemicals, iron, steel and ferro-alloys in addition to primary aluminium and other metals. The contracts for ordinary and flexible power are different. Flexible power can be stopped in the event of limited net capacity.

Consumption without power-intensive manufacturing and extraction

Consumption without power-intensive manufacturing and extraction is net consumption of electric power less total consumption in power-intensive manufacturing and extraction of crude petroleum and natural gas. Households, services and manufacturing other than power-intensive manufacturing account for the majority of this consumption.

Electricity annual

Gross production of electricity refers to the production that is measured on the generators. The net production may also be calculated by subtracting own consumption in the power stations.

Exports of electric power is power produced in Norway that crosses the Norwegian border.

Imports of electric power is power produced abroad that crosses the Norwegian border.

Gross consumption of electricity is the sum of gross production of electricity and imports less exports of power.

Pump consumption is power used to run pump stations that elevate water from a lower to higher level.

Other own consumption contains light and heating in the power stations in addition to engines, compressors and other production equipment.

Ordinary consumption and flexible consumption: The contracts for ordinary and flexible power are different. Flexible power can be stopped in the event of limited net capacity.

Electricity price, i.e. the price that households pay to the electricity suppliers. This part of the power market was deregulated in 1991. Costs relating to electricity certificates, which is a subsidy system for renewable power, are included in the electricity price. According tothe Norwegian Water Resources and Energy Directorate (NVE) and the Swedish Energy Agency, the cost of electricity certificates was about 1 øre/kWh in 2012 and 2013.      

Grid rent, i.e. the price that households pay for the physical distribution of electricity. Unlike the deregulated electricity price, the grid rent is regulated. 

Taxes consist of tax on consumption of electricity, value added tax (VAT) and subsidies to Enova. All counties in Norway have the same tax rate for the consumption of electricity, apart from some parts of Troms and the whole of Finnmark, which are exempt. The Enova tax was 1 øre/kWh in 2014 and is the same for all households throughout the country. VAT is added after electricity price, grid rent and other taxes have been added. Nordland, Troms and Finnmark are exempt from VAT.   

Production value is defined as turnover corrected for changes in stock of finished goods, work in progress and goods and services bought for resale.

Cost of goods and services consumed is the value of goods and services consumed as input in the production process; excluding fixed assets (consumption is recorded as consumption of fixed capital).

Value added is the sum of production value minus the cost of goods and services consumed.

The consumer groups in the table with information on electricity consumption in Norwegian municipalities have the following content.

Mining and manufacturing etc: Mining and extraction, power intensive manufacturing, manufacturing excluding power intensive manufacturing and various supply and remidiation activities.

Services etc: Transportation and storage and construction and other services.

Households and agriculture etc: Agriculture, forestry and fishing, hot-houses, private households and cottages and holiday houses

Standard classifications

Electricity monthly

Production and consumption of electricity is measured in Gigawatt-hours (GWh). In StatBank, Megawatt-hours (MWh) is used as a measure. The classification is based on the standard industrial classification 2007 (SIC 2007). A description of which industries are covered by the statistics is given in section 3.1.

Electricity annual

The classification is based on the standard for sector classification 2007 (SN2007). There is a description of which industries the statistics comprise in section 3.1.

Background

Background and purpose

Electricity monthly

The purpose of the statistics is to map the production and consumption of electricity. The monthly electricity statistics also serve as a basis for analysis and reports. The current statistics date back to 1979.

Electricity annual

The purpose of the statistics is to give an overview over economic key figures of the power market and to follow the development in supply and use of electricity on national level and on county level. The statistics go back to 1937, but have been changed several times since then.

Users and applications

Electricity monthly

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.

Equal treatment of users

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

Coherence with other statistics

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.

* Main office activities in own enterprises

 

Data sources and sampling

Electricity monthly

Statistics Norway receives a dataset from Elhub six days after the reference month containing  data on production and consumption of electricity for 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 use and electricity consumption in Extraction of crude petroleum and natural gas which is used in the monthly electricity statistics. In the beginning of 2020 electricity consumption in Power-intensive manufacturing will also be calculated using the Elhub dataset as source.

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 8 establishments (approximately a total count).

Power-intensive manufacturing consists of approximately 70-75 establishments (approximately a total count).

Electricity annual

Data collection together with Norwegian Water Resources and Energy Directorate.

Total Count.

Collection of data, editing and estimations

Electricity monthly

Statistics Norway receives a dataset from Elhub with measured values for production and consumption of electricity for all metering points in Norway. At the moment electricity consumption in power intensive manufacturing is collected in own surveys by Statistics Norway, but this survey collection will end when we are ready to use the electricity consumption data from Elhub (in the beginning of 2020). Since Svalbard is not included in the Elhub data, electricity data from Svalbard are 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, duplicates in data. Data on consumption for every establishment in different industries are edited. Where there are major changes compared with previous figures, the establishment is contacted. 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

Seasonal adjustment

Not relevant

Confidentiality

Electricity monthly

According to § 2-4 of the Statistics Act, collected data are subject to secrecy and must be kept or destroyed in a secure manner. Any use of the data must be in accordance with the rules set out by the Data Inspectorate.

Electricity annual

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.

Comparability over time and space

Electricity monthly

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.

Time series can be downloaded from table 06901 and 08583 in the StatBank.

Electricity annual

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.

Accuracy and reliability

Sources of error and uncertainty

Electricity monthly

The results of a statistical survey normally contain certain collection and processing errors. Collection errors can occur due to a respondent giving incorrect information because they misunderstand a question, or they may forget to answer a question. Processing errors can occur in the data during the optical reading or during revisions of the sample.

Despite various data controls, errors can still occur. These can include errors that were not possible to detect during the control routines or incorrect evaluations by executive officers in Statistics Norway.

The statistics are based on a full count, and thus there are no sampling errors.

Revision

Electricity monthly

The figures of electricity generation are not revised after the release of the statistics. Minor revisions may occur for the figures of exports, imports and consumption.

Electricity annual

If no large errors are detected after the release of the statistics, the figures are not revised.
