The power substation nearby blew another transformer. First there was a loud noise and power to TV and heater went off then back on. Another loud noise and power went out completely. Not bad for me because I run off batteries for lighting so they didn’t even flicker. I wasn’t stuck in the dark! Lost electric heater but main heater is propane so I just switched over. Very nice. Add in the ability to move my entire home at a moment’s notice with ALL my things in cases of emergency and this is pretty nifty.
