​​​​​What are rate riders?

Rate riders are a special credit or charge on a customer’s bill in addition to the tariff distribution rates approved by the AUC. The rate rider is a mechanism used to flow through costs that are incurred by a distribution utility or refunds provided to the distribution utility, that were not included in its tariff distribution rates at the time those rates were approved by the AUC. All rate riders must be approved by the AUC before they are applied to customer bills.

When a rate rider is determined to be needed by a utility, it applies to the AUC. Upon approval, the rate rider is applied on utility customer bills for a determined amount of time. Below are the current riders in effect for each regulated utility.
