Would it be right to ask something about power grids at Electrical Engineering? I'm interested in the history of the 345 kV voltage level.
My question relates to the following:
According to this source it was first applied in 1953 by American Electric Power, but much more is not available at the forefront of the internet. I would like to know where this line was, who has tried this and why e.g. Texas (ERCOT) still sticks to 345 kV as highest voltage, despite 500 kV would be much more economic.
