“but few loads really cared too much.“ There’s some room for error, but frequency is the a very important metric for the utility to get right. The reason is that motors start to burn when the frequency is significantly off of the design f [1]. So, the blower in your furnace will die (-> no heat in the home). Your laundry machines’ motor burn. You ovens convection oven burns. Etc. You’re better of with rolling black ours (Texas forgot the “rolling” part) than get the frequency wrong. [1] think of a motor as an LCR circuit. There’s a natural f, and if youre far from it it will cause heating of the windings
