Understanding Your Rates

Understanding Your Rates

When reviewing your bill each month, do you ever wonder why your monthly service charges may differ from other businesses or why your account has been classified on a certain rate schedule?

Each account currently on a General Service rate is reviewed annually to determine whether the account is on the appropriate rate. Your business’s energy usage and load characteristics determine which rate you qualify for; should either of these factors change, you may no longer qualify for the rate schedule that you have been previously assigned.

Below is a chart that depicts the monthly service charges for each rate classification. If you have questions/concerns regarding your rate classification or monthly service charges, click here to review your rate tariff or feel free to contact us directly at (520) 744-2944.
