Class B Global Adjustment

The IESO publishes three variations of the Class B GA rate for each month in order to accommodate the various billing cycles for all of Ontario’s Class B customers. The published 1st and 2nd GA Rate Estimates are based on projections of monthly costs that are covered under GA and also include a true-up component to cover any over-collection or under-collection which resulted from the previous month’s published rates. The 1st and 2nd GA Rate Estimates are also based on the projected total energy consumption within Ontario during the month for which the rate is being calculated. The published Actual GA Rate for the month is the representation of the actual GA costs which are allocated over the total energy consumed in Ontario by Class B customers. The Actual GA rate also includes a true-up component to cover any over-collection or under-collection which resulted from the previous month’s published rate. The Class B rate that is applied by LDCs to bill their customers should not affect the overall amount that is paid by the customers over time if the rates continue to be applied consistently.

On May 9, 2019, legislative amendments to Ontario Rebate for Electricity Consumers Act, 2016 and the Ontario Fair Hydro Plan Act, 2017 (OFHPA) were passed to end Global Adjustment Refinancing and replace it with a new rebate, the Ontario Energy Rebate (OER), effective November 1, 2019. The OER is an expansion of the 8% provincial rebate and replaces the GA Modifier under the OFHPA that reduced the GA payable by eligible customers on electricity consumed.
