Could have just fired up a fleet of railroad locomotives and tied them into the network. They did this in Canada.
Too bad our government leadership doesn’t have any entrepreneurial creative thinkers these days. It would be very interesting to know what would’ve happened under President Trump. Most likely Washington would not have waited until a week AFTER the deep freeze begin to declare an emergency.
Back in the late 1960s, a hurricane hit Hawaii and knocked-out all generating stations on one of the islands.
As a result, there was no way to get power, since the field coils in the generators couldn’t be energized.
To fix the problem, it was arranged for a submarine to dock there and basically “jump-start” the island.
I remember seeing a picture of the submarine at the dock, with a cable that looked to be about 6” in diameter coming out of the conning tower and running down the pier.
