I'm not expert, but it seems inaccurate that Iceland is listed as part of the RG Nordic area, considering that there aren't any submarine power cables connecting Iceland to anywhere else. The map on the Synchronous grid of Continental Europe article shows it as a separate grid, and even explicitly states that "The networks of Iceland, Cyprus, and Malta are not yet interconnected with the other grids." Should this be changed? -- Phantom784 (talk) 04:49, 6 February 2012 (UTC)

I agree Phantom784. Iceland is not part of the RG Nordic. It's far away across the sea. The map needs revising. (talk) 09:04, 9 September 2015 (UTC)

Energy efficiency of regional grids[edit]

Can someone help me verify some data presented in the "Major existing networks" section of this article? If my math is correct, then the electricity used by an average person per day varies widely by region. Below are three such regions:

  • NORDEL: ~43 kWh/person/day (i.e., 43 = 390x10^12 / 25x10^6 / 365 / 1x10^3)
  • UCTE: ~15 kWh/person/day
  • IPS/UPS: ~13 kHw/person/day

Is it really possible that the average Scandinavian uses nearly 3 times as much electricity as the average, say, German? That doesn't seem right. Or, is my math wrong and/or I am missing something? --Thorwald (talk) 23:15, 25 September 2009 (UTC)

Yes, that sounds about right. There are several reasons why the Nordic countries use much more electricity than central Europe:
  • The main reason is that due to a high proportion of hydroelectric power the Nordic countries have much cheaper electricity than central Europe. (Sweden gets almost 50% of its electricity from hydroelectric power. Norway has an even larger share.)
  • The Nordic countries have large mines and lots of forest, thus we have many large ironworks and paper mills. Those industries use huge amounts of electricity. Due to the cheap electricity the later stages of the processing is also often done in the Nordic countries. Also, the Nordic ironworks usually use electric induction to heat the ores and metals, where the German ironworks use coal or natural gas.
  • Due to the pricing electricity intensive industries such as aluminium production is placed in the Nordic countries instead of in Central Europe.
  • Due to the pricing many Nordic houses are heated with electricity. While for instance German houses usually are heated with natural gas or coal. (Germany is connected to the gas fields in the North Sea and Russia through pipelines.) Germany uses lots of natural gas, while the Nordic countries don't use much gas at all. Up until recently Sweden wasn't even connected to the European gas pipelines. So if you want to compare Nordic and Central European energy usage, you need to also count in the gas and coal usage.
  • Since the Nordic countries have a large part hydro power we don't have problems with peak power consumption. While in Germany there are special much higher pricing when an industry uses peak power. Thus many factories in Germany have their own gas or diesel powered electric generators that they use during their peak consumption, like when they start their heavy machinery in the morning. That generation of electric power is not counted into the official electricity statistics.
  • In the 1980's I travelled around Europe by train. I noticed that the German railways still used diesel locomotives on many lines, while Swedish railways were already fully electrified since decades. Again, the reason probably is the cheaper electricity in the Nordic countries.
  • Due to the pricing Nordic countries "waste" much more electricity. For instance, when my German relatives come and visit me in Sweden they are usually astounded by how well lit the Swedish cities are.
  • I could list many more examples of how the Nordic Countries use more electricity than Central Europe. Or that we use electricity instead of gas, coal and diesel. In most cases the reason is that the Nordic countries have cheaper electricity.

European Frequency[edit]

It was my understanding that Western Europe was 60Hz, while Eastern Europe was 50Hz. LorenzoB (talk) 16:39, 26 October 2010 (UTC)

Nope, all of Europe uses 50 Hz, and has done so for a long time. --David Göthberg (talk) 16:15, 11 July 2011 (UTC)


Is "When [china's planned grid is] complete, its generation capacity will dwarf that of the UCTE Interconnection." really unnecessary? It seems like bragging to me. --Test35965 (talk) 09:00, 25 November 2012 (UTC)
