I cannot find clear, readable maps showing the North American Grid but, from what I can see it seems that eastern S. Dakota is a regional hub and there are connections to Minneapolis. There is significant population density in Minnesota and it might be feasible to upgrade lines from South Dakota and finance lines from the reservation to the South Dakota hub. That could be a very green way to warm the hearths of Homo Minneapolis in very cold winters. Upgrade a few more lines and you have a way to cool hot summers in Chicago.
