Global Adjustment Components and Costs

Actual Global Adjustment Components

The three values below represent the main components of the global adjustment used by the IESO to calculate the monthly global adjustment rate:

  • GA-OEFC-NUG (M$) - Contracts administered by the Ontario Electricity Financial Corporation with existing generation facilities
  • GA-OPG (M$) - Ontario Power Generation nuclear and baseload hydroelectric generating stations
  • GA-OPA (M$) - Contracts with the IESO (and with the former Ontario Power Authority) for new gas-fired generation, renewable facilities, energy from waste and biomass, nuclear refurbishments, as well as conservation programs.

Global Adjustment Costs and Consumption by Customer Class

Total global adjustment costs and consumption figures are divided between Class A and all remaining, or Class B, customers. Class A customers pay a rate based on their proportion of energy use during the five established coincident peaks. The remaining costs are recovered from all Class B. The breakdown between the two groups is shown below.
