Electricity statistics, annual
10.08.10 - Electricity, gas, steam and hot water supply
Annual. The statistics are published 1 ½ year after the reference year.
The figures are on national and county level. The statistics Energy use by municipality contain figures for consumption of electricity on municipality level.

The annual electricity statistics are reported to Eurostat and the International Energy Agency (IEA).
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.
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.
The Annual electricity statistics of 2006 were based on data from 317 electricity plants.
The Electricity statistics contain:
• All utilities and traders engaged in retail and wholesale of electricity
• Grid operators
• Production plants having rated output of minimum 100 kW
• Production plants operated by other industrial concerns to supply own factories having rated output of minimum 500 kW
The Electricity statistics do not contain:
• Power stations which although partly owned by Norwegian interests are located outside Norwegian territory.
• Electricity production on the Norwegian Shelf
• Main office activities in own enterprises
Co-operation with Norwegian Water Resources and Energy Directorate on most of the data collection. In addition, Statistics Norway collect data from approximately 35 electricity utilties – basically industrial utilities.
Total count.
As of 2000, the electricity utilities have reported their data electronically via the system ERAPP.
Among other things, maximum and minimum values in addition to percentage changes are calculated.
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.
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.
Calculated net loss: Loss on exports, consumption of non-priority power in power-intensive manufacturing and pump storage use is 7%. 3% loss on consumption of priority power in power-intensive manufacturing and 10% on consumption without power-intensive manufacturing. The net loss depends among others on distance, temperatures and the quality of the grid.
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 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.
Errors may occur when concepts are misinterpreted and in the completion of forms. In addition, mistakes may occur in the data collection.

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 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.
Monthly and annual electricity statistics correspond well.
