Electricity Charges

Cost of Power

This line item reflects the cost of electricity purchased by Oshawa Power on your behalf for usage at your service address. This is a pass through charge, paid directly to suppliers with no mark-up for our customers.

Based on your current Terms of Service, your Cost of Power will be calculate dependent on your pricing plan. Possible rates include Time-of-Use (TOU) rates, Tiered rates, Hourly Ontario Energy Price rates, or Retailer Contract rates.

Global Adjustment

The Global Adjustment (GA) cost is designed to cover the cost of developing, maintaining, and refurbishing electricity infrastructure and generation resources as well as delivering conservation programs across Ontario. This is a pass through charge, paid directly to suppliers with no mark-up for our customers. All customers are placed in one of two GA categories; Class A or Class B.

Class A

Class A customers include all participants in the Industrial Conservation Initiative (ICI). These customers are charged a portion of the overall GA based on their Peak Demand Factor (PDF) which is based on their percentage of total demand during the top five peak hours of the base period.

Class B

All other customers are considered Class B. For Wholesale Metered and Retail Contract customers, GA costs are calculated using the 1st GA estimate and consumption. For small business and residential customers enrolled in Time-of-Use (TOU) or Tiered pricing, GA costs are included in TOU and Tiered rates and will not appear as a separate line item on your bill.
