kWh stands for kilowatt hour – or how much power is used in a given hour.

The price to compare is your local utility's current kWh rate.

A supplier is a company that acquires electricity and sells it to customers at a competitive rate.

A utility controls the delivery of power to your home or business. They're responsible for maintaining the utility poles and power lines, restoring power after an outage and sending your bill. This will not change no matter who your electricity supplier is.

A variable rate can change month to month.
