Understanding My Bill

At GrandBridge Energy, we want to help you understand your bill, and provide you with helpful new ways to view and manage your consumption.

Calculating Your Bill

Use the OEB online bill calculator to get a monthly bill estimate for electricity whether you buy directly from GrandBridge Energy or you’ve signed an energy contract with an electricity retailer.

The total amount on your energy bill comes from three costs: Electricity Use, Delivery, and Regulatory.  Learn more from the Ontario Energy Board.

Customer Choice

If you’re a residential or small business customer that pays Time-of-Use (TOU) electricity prices, you can choose to switch to Tiered prices or Ultra-Low Overnight rate plan and back to Time-of-Use at anytime.

To switch your electricity rate plan, you must notify GrandBridge Energy by completing a Customer Choice Election Form available on our website or by contacting us at 519-751-3522.

Electricity Commodity Charges

This is the cost of electricity supplied during the billing period and is calculated on the adjusted kilowatt hours (kWh) used. GrandBridge Energy collects this charge and passes it directly to our electricity suppliers.

Delivery Charges

Delivery is the cost of bringing electricity from generating stations to your home or business and is calculated using the readings on your meter that record your usage. Delivery charges include: Transmission Charge: Added Network Service Rate and Line and Transformation Connection Service Rate. The Transmission Charge covers the costs of transmitting electricity from generators to Brantford.

Distribution Charges

Distribution Charges help pay for delivery of electricity to your home, as well as the cost of designing, building and maintaining the power-distribution system. You will pay a different charge if you are signed up with a retailer.

Regulatory Charges

Wholesale Market Service

This charge covers costs such as market regulation and the management of the system. It is calculated on the adjusted kWh used.

Standard Supply Service (SSS) Rate

The Standard Supply Service is an administration charge of $0.25 per month. The SSS is prorated based on days of service over an average month. Please note that this charge does not apply to customers who purchase their energy from a retailer.

Adjustment Factor

When electricity is delivered over a power line, it is normal for a small amount of the electricity to be consumed or lost. This is because equipment such as wires and transformers consumes power before it gets to your home or business. The adjustment factor helps make up for these losses.
