Blue Ridge and generator - worth it?

[Alton Johnson]

Hi there. We just acquired a cabin in Blue Ridge from owners who previously used it for short term rentals and now we've got our first guest. Unfortunately, today (Christmas), TMC Electric had an outage, and of course we're freaking out because this obviously sucks and will likely affect our rating. It appears that there's just a little bit of rain going on, but nothing crazy. 

That being said, the questions that I have here are:

1. Does the Blue Ridge/Epworth area experience outages quite often?

2. Is a backup generator worth it for a STR in this area?

Thanks for any input.
