The electricity sector in Norway relies predominantly on hydroelectricity. A significant share of the total electrical production is consumed by national industry.


Of the total production in 2011 of 128 TWh, 122 TWh was from hydroelectric plants, 4795 GWh was from thermal power, and 1283 GWh was wind generated.[1] In same year, the total consumption was 114 TWh.[1]

The annual electricity consumption was about 26-27 MWh per inhabitant during 2004-2009 when the European union (EU15) average in 2008 was 7.4 MWh. Norway’s consumption of electricity was over three times higher per person compared to the EU 15 average in 2008. The domestic electricity supply promotes use of electricity.[2]

Norway has an open electric market, integrated with the other Nordic countries. Export and import is routine over the direct power links to Sweden, Denmark, Germany and the Netherlands. The market is handled by NASDAQ OMX Commodities Europe and Nord Pool Spot. Many of the hydroelectric plants in Norway are easily adjustable and can adapt well to variations in demand, and hence in price. On a normal day, when price is low during nighttime, Norway normally imports power, and exports during daytime when the price is higher.

West of Oslo, there is a smallsingle-phase AC power grid operated with 16.7 Hz frequency for power supply of electric railways, see Electric power supply system of railways in Norway.

Fuel mix disclosure[edit]

Average fuel mix for electricity consumption in Norway

  Fossil (42.2%)
  Hydro (35.8%)
  Nuclear (21.5%)
  Biomass (0.4%)
  Wind (0.1%)
  Solar (0.0%)

The annual share of renewable electricity in the Norwegian market dropped in 2010 to 24%. It is expected that this share has declined further in 2011. Consumer who do not purchase renewable electricity, will get more than 75% from non-renewable sources such as coal, gas and nuclear power.

Source percentage (2010)
Fossil 42.2%
Hydroelectricity 35.8%
Nuclear power 21.5%
Biomass 0.4%
Wind power 0.1%
Solar power 0.0%
CO2 286 g/kWh
Nuclear waste 0.0022 g/kWh

This is the result of Norway exporting the bulk of its Guarantees of Origin.[4][dead link]


During the last few years a combination of high power prices in the market and less than usual rainfall has made the power system more vulnerable to power shortages. So far consumers in Norway have noted this by paying a higher price for electrical power during wintertime, however still a low price in international terms.

Mode of production[edit]

Hydroelectric power is the main mode of production. Wind power offers huge export opportunities. Norway’s potentials for wind power are excellent and the electricity production exceeds its own use. The solar industry development in Norway is significant.


Norway is known for its particular expertise in the development of efficient, environment-friendly hydroelectric power plants.[5] Nationwide installed capacity of hydropower amounted to 29 GW in 2007.[6] In 2008, hydroelectricity generated 141 terawatt-hours (TWh) and accounted for 98.5% of the national electricity demand. This was also 4.3 percent of the worldwide generated hydropower and according to the IEA, Norway ranked 6th for that year, behind China, Canada, Brazil, the United States and Russia.[6]

Solar power[edit]

The national support for solar power is in place since 2008.[7] For 2013, the European Photovoltaic Industry Association reports a negligible 0.02 watts per habitant or less than 0.1 megawatt (MW) of installed photovoltaic capacity in Norway. This is a hundred times less than in Finland (2 watts per habitant), two hundred times less than in Sweden (4 watts per habitant) and almost five thousand times less than in Denmark (98 watts per habitant).[8]

Solar companies include Renewable Energy Corporation REC, Elkem Solar and NorSun. REC is a solar power company with headquarters in Norway. It has solar manufacturing facility in Bécancour, Quebec, Canada and the United States. Revenue was NOK 13.78 billion in 2010.[9] Elkem Solar was part of Norwegian Elkem. Orkla Group sold it with $2 mrd. in January 2011 to a Chinese chemical company China National Bluestar head office in Beijing.[10] NorSun is a private solar cell producer.[11]


Norway has imported up to 10% of its electricity production during 2004-2009.)[3] According to IEA the net electricity export was 14 TWh and the hydro power production 141 TWh in 2008.[6]

A new high-voltage link between Nea in Norway and Järpströmmen in Sweden was commissioned in 2009.[12]

Norways grid is connected with the NorNed-cable to the Netherlands. There are plans for cables with the Germany (Norger) and the UK (Nordlink).
