Here is what purports to be a map of various power transmission lines:
https://www.gridstatus.io/infrastructure-map?zoom=3.22¢er=-95.70000,37.97081
Roll your mouse over the "765 kV" line on the left, then move directly right and you can select "Only" and see the map with only 765 kV lines on the map. Most 765 lines are in Quebec and the midwest.
Anyone have a 765kv power line in there area?
