I agree on the suspect, it does sound fishy. But... Many people I know are using heat pumps with electric backup. With the newer heat pumps they are good for the teens and even some split units down close to 0. Even the older ones only need back up heat a few days a year because they are good into the 20s, so I can see where these temperatures would cause more demand but seems like it should be with in range of availability. I have LP backup for my heat pump and it even will run on a backup generator when needed.
I did hear some where, that two fossils fuel power stations were down for some reason. If true I can see where they would fall behind.
