Discussion regarding the creation of this page may be found at Talk:Grid connection, where much of the material of this article came from. -J JMesserly (talk) 18:29, 22 November 2008 (UTC)
I used the image with the caption: "General layout of electricity networks. Voltages and depictions of electrical lines are typical for Germany and other European systems." for some academic work in Germany and my professor noted the caption 'Low Voltage (50kV)' this is too high generally for low voltage. He has advised me that Low voltage is less that 1kV, and Medium Voltage is between 1 and 60kV. Thus on my version of the diagram I have changed the image to read Low / Medium Voltage (<60kV). I was not able to attach the image without an account. Sorry. Nathan K. www.madteckhead.com
I updated the image to a .SVG file and cleaned it up a bit using the same values as Nathan K. had. --MBizon (talk) 20:14, 8 March 2010 (UTC)
Even knowing that it's German, seeing 250KV labelled "extra high voltage" while more common (in my area) 750KV is barely "high voltage" is quite odd. Perhaps these voltage figures must be removed altogether? East of Borschov (talk) 12:00, 12 June 2010 (UTC)
I would hesitate to include the power producers as part of the electric grid, just as a matter of semantics. Delivery and production are two separate things even if one depends on the other. The term ‘network’ also relates to interconnectedness and not production. My argument is that the grid is a delivery system of (in this case) wires connecting producers and consumers, and does not include the producers and consumers; it is the name of the thing that runs between them. I do not believe this is made clear in the article.
The article needs a section on how auctions determine which power plants produce how much electricity to meet demand. Demand (and therefore supply) varies day to day and minute to minute. These are some sources, especially the World Bank study on long term auctions, but not much on intra-day auctions to vary power throughout the day:
