Electricity

Electricity monthly

Total production of electricity

Electricity generation contains net production. Net production is defined as gross production minus cunsumtpion of electricity in the power plant. Pump storage and industrial processes 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 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.

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 definition corresponds to the following codes in the standard for sector classification (2007) :

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

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.

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

Electricity monthly

Production and consumption of electricity is measured in Gigawatt-hours (GWh) in tables. In StatBank, Megawatt-hours (MWh) is used as a measure. The classification is based on the standard industrial classification 2007 (SIC 2007).

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.

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

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

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.

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.

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 also occur 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.
