As I recall, there are 3 major power grids in the country. There is one in the east, one in the west and one in Texas (mostly). I believe they are all separate and do not send power from one to another. I state that from memory but I could be wrong.
I have not heard anything about it, but I can't help but think of a certain person who said they wanted to bankrupt the coal industry. How many power plants were shut down as a result?
Wind power is great under normal circumstances but is crap in emergency situations. Too much wind is as bad as too little. There has to be reliable, standby generating power source for the high demand times.
