What a nightmare. So I'm on a trip to Albuquerque for a family wedding and I pull into the Trinidad, CO supercharger with less than 50 miles on the guess-o-meter. No blue/green light, I try multiple chargers and everything's dead. A snowplow driver that's clearing the parking lot gets out of his truck and walks over to tell me that the entire area has been out of power for 1.5 hours.
I call Tesla and somehow - magically - they find out that the local utility lost a high-tension power line and there is NO ESTIMATE when power will be restored. Interestingly, there's power one exit back up the highway but NOT at the supercharger where I need it. Tesla does a great job telling me about charging opportunities nearby, but they're all RV parks and they're either in the same power desert I am or they're not answering the phone. It's winter here and many RV parks are closed during cold weather.
The comedy of errors just keeps doling out the hits...I make it to a hotel but their manager won't let me even think about plugging into a laundry dryer outlet. I realized that I didn't even have a 120v extension cord with me, so I go to the local hardware store and spend $120 on two high-quality extension cords should the worst happen. After it's clear the power's not coming on, I call Tesla (while my phone power is waning) and they kindly arrange a tow for me all the way to the Las Vegas, NM supercharger. With all the snow, it's going to be 2+ hours before the tow truck gets to the SC location. I drive to the SC and leave my car with 43 miles left on the battery and walk to the nearby hotel, also without power. Luckily the water still flows, so the nice hotel staff will give you a flashlight so you can use the bathroom.
Short of the story, 6 hours after the outage starts, the power goes back on. There are many more nuances to this story - alternate places to charge, frantic phone calls, etc. but I just don't want to keep typing. I'm sure the relatives are going to make fun of my fancy electric car that can't make it to Albuquerque when a gas car could.
Tesla was GREAT, I was able to cancel the tow before they charged me and I charged in Trinidad enough to get to Las Vegas, NM (where I am now). What a pain. The Trinidad locals didn't have any good things to say about the local utility, let me tell you...I thought I'd be spending the weekend there trying to recharge on 120v. What a mess.
