You might be interested to learn that so far since the major deregulation wave in electric utilities over the past 20 years or so, no one has been able to show any real pricing benefits for the end consumer.

Certain industries are inherently slanted towards a monopoly, and a regulated monopoly is often preferable to an attempt at forcing market conditions. The two industries aren't the same, and I think electric/gas utilities are significantly more inclined towards a natural monopoly, but it is important to realize what situation we currently have, rather than applying an idealized narrative.
