I did a tour of the power plant at Notre Dame university (in Indiana) back when I was in high school. They have their own coal plant on site where they get a portion of their power along with diesel generators as backup for that. Apparently they get the rest of their power at a reduced rate from the local utility because of an agreement that they can temporarily go fully off grid if the power company requires it.
