Greater depth on capacity required
If there is to be serious displacement of 1GW coal plants being installed in regional proximity to Chinese, European or North American cities from renewable sources such as enormous solar and wind farms in distant deserts or wind swept plains, then the required capacity is not going to be order of 2 or 3 gigawatts per transregional HVDC corridor, but one or two orders of magnitude greater. At one coal plant per week, china would require on the order of 50 gigawatts of additional long distance transmission capacity per year simply to prevent further increasing its CO2 contribution, which is already dangerously high. So for a "superhighway" I am not picturing typical single level HVDC pylons, but something with ten or 20 times the capacity.

Steven Chu is saying HVDC is the only way to go and that seems right, but the only serious study I have seen so far is the one AES is pushing for HVAC, and it claims 400GW of capacity for wind. But consider the the pathways to East coast cities on the map they are proposing. There are multiple places where there only are three lines or 4 lines on the east west path, so even if only half the wind is going to the eastern cities, that means these 765KV lines are transiting 50 to 70GW? This implies they would need to bunch 10 or 20 HVAC pylons along these corridors, but surely this is not what they are proposing. What is the correct picture people should have? -J JMesserly (talk) 22:36, 16 December 2008 (UTC)

1930s project opposed by who and why?
Does anyone have more information about about the opposition and scrapping of the project to send hydroelectric power from the NW to Southern California mentioned in the History section of this article? —Preceding unsigned comment added by Sfisher (talk • contribs) 20:47, 10 June 2010 (UTC)

Propose merge
Is there any significant difference between this and the SuperSmart Grid? If not, let's merge!--Graham Proud (talk) 08:59, 3 January 2014 (UTC)
 * Agree. There's an enormity of overlap between this article Super grid, European super grid, SuperSmart Grid, Unified Smart Grid, Asian Super Grid, Desertec, and Medgrid, all of which seem to be articles about hypothetical projects. --Cornellier (talk) 17:14, 19 April 2021 (UTC)
