I haven’t done the analysis myself, but I highly doubt winterization would double the cost of energy. It’s probably some small portion of the capex to build the plant in the first place. Would you pay an additional 5% or 10%? Probably, especially if you get to avoid your home being flooded by burst pipes, rendering it potentially unlivable for much longer than the week of power outage.
