What is a serving utility?

A serving utility refers specifically to the utility company that directly sells electricity to consumers or businesses. This entity handles the distribution and retailing of electricity, ensuring that the energy generated reaches end-users effectively. The company engages in billing consumers, maintaining customer service, and providing necessary information regarding energy usage.

The other options describe different roles within the utility sector. The entity generating electricity focuses on power production, while another might deal with regulating utility rates but doesn't engage directly with consumers. Maintenance on electrical devices relates to service and support after the electricity has been supplied, but this also doesn't align with the definition of a serving utility. Thus, the choice that accurately captures the essence of a serving utility is the one regarding the company selling electricity for resale.
