Your service territory comes first
A state can contain many utilities, cooperatives and municipal systems. In competitive retail areas, the seller and the company delivering electricity may be different. Check the service territory, residential class and meter configuration before comparing an advertised plan.
Test more than the headline cents per kWh
List supply, delivery, fixed customer charges, taxes and any usage-dependent credits separately. A promotional effective price at one monthly usage level can change substantially when consumption changes. Enter a second scenario at your own kWh rather than relying on a representative household.
Use averages for context
The existing regional guide includes dated EIA residential averages. Those are reported market statistics and should not be loaded as a currently available retail offer. Keep a written source for a quoted rate and check the effective date, contract duration and cancellation conditions.
