What do you mean by electricity utility? Which organisation specifically? The electrical supply is usually formed of multiple organisations with different responsibilities, which usually works pretty well, but it generally means that e.g. storage, transmission, and generation are not one single organisation.

Yes, including because firms at one level of the supply chain (eg, transmission) are in many countries precluded from operating in another level (eg, generation).
