I'm having a 22k Generac whole-house generator installed next week. I already have a concrete pad near the service entrance so installation shouldn't be very expensive. Only 5k at Home Depot, the cost of a TOTL arranger. My entire house is electric except for the kitchen range, outdoor grill, and the gas fireplaces. We have very few outages as all of the electric power in our neighborhood is underground and not subject to falling trees, etc., still, it's cheap insurance. We had one major blackout during the winter of 2018 (2 1/2 days without power) and that was enough for me. I had a similar setup in my house in Florida; there it was really necessary. Had a large but portable setup in Hawaii because, where we lived, no electricity also meant no water.

It's funny how we think some things are extravagant, UNLESS it's something we want.....like an expensive keyboard .
