except TVA generates its own power and nuclear is considered 'uninterruptible', right? They elected to interrupt is how the news articles are relaying it: TVA ASKED local utilities to go offline voluntarily and they did. WTF?! There are contracts between providers and customers and laws governing interruption of power services when temps fall below a certain degree. These voluntarily blackouts breached ALL of those agreements is my point. There was no point or purpose except to basically to show what they can do, and they did it without regard to customers and the impacts these voluntary blackouts had on them.
