The utilities have been granted a monopoly by the govt, and in exchange, are subject to regulations. If anything is a "naked display of political power" it is the granting of a monopoly.
The reason the monopoly is granted, is that it is most efficient as a society to have a single successful power distributor than to have multiple failing ones with redundant infrastructure (power poles, lines, etc.). And, for monopolies, to regulate them to reasonable profits instead of allowing any winner of the failing competitors to establish a rapacious monopoly.
With new developments in rooftop solar and batteries making it economical, it is sensible that these distributed modes be supported, and the system migrated towards distributed power. I've always wondered why this wasn't done sooner as a civil defense measure (as the interstate highway system was built as a defense measure, to transport troops to either coast in 24h). As such, they are only being forced to subsidize their customers' ability to either generate power or live at greater efficiency.
