Global Adjustment​​​

The Global Adjustment (GA) covers the cost for providing both adequate generating capacity and conservation programs for Ontario. It is the difference between the hourly Ontario electricity price and the rates paid to regulated and contracted generators, and for conservation and demand management programs.


For more information see Global Adjustment.

Global Adjustment (¢/kWh)

All customers pay the Global Adjustment.  Class A customers (large volume users) pay based on an annual determination of their coincident peak demand ​which in turn specifies their share of the Global Adjustment costs.  Class B customers pay a share of the global adjustment through the Class B Global Adjustment rate or through the Regulated Price Plan.

The IESO publishes three variations of the Class B rates. The 1st Estimate for the Global Adjustment (GA) looks ahead to the following month's Class B rate, based on Ontario demand forecasts, estimated contract and program costs and true-ups from previous months. It is primarily used by local distribution companies for billing purposes - and for many customers is the value they will see on their bill.  While the 1st Estimate is not calculated as a forecast of actual GA costs, it can provide consumers a guide against which they can compare real-time market prices. The monthly actual GA is published after the fact and is calculated using final demand and cost information.  More information about the application of the Global Adjustment.
