GrandBridge Energy business customers are billed according to their rate classification, which is determined by the amount of electricity that is consumed monthly and the service size.


The Ontario Energy Board (OEB) sets all electricity rates in Ontario. For information, please visit the Ontario Energy Board’s website.

Your electricity bill is made up of Electricity, Delivery (including transmission and distribution) and Regulatory charges. All other charges are collected on behalf of other parties. Our utility retains only the Monthly Service Charge and the Local Distribution charge.

Electricity Charges

The Electricity charges on your bill will be based on prices set by spot market pricing through the Independent Electricity System Operator, the Ontario Energy Board or based on a contract with a Retailer. Electricity charges are collected by GrandBridge Energy (Energy+) and paid directly to electricity suppliers. We do not keep any of these charges.

 IESO Sport Market Price

Customers with an interval meter pay the Hourly Ontario Energy Price, also known as the spot market price for their electricity, plus Global Adjustment Charges. The Spot price is determined by matching supply with Ontario's demand for electricity in the real-time market operated by the Independent Electrical System Operator (IESO). In Ontario, all electricity rates reflect the wholesale electricity price in some way. The wholesale price of electricity is dynamic − changing hourly based on demand and the availability of supply. Factors impacting demand include consumer behaviour, weather, time of day, day of the week, as well as economic conditions.

Customers without an interval meter pay the Weighted Average Hourly Price (WAP) for their electricity.

 OEB Regulated Price Plan (RPP)
As a small commercial customer, you are automatically part of the Regulated Price Plan (RPP) for the purchase of Electricity. This means you are charged a regulated price per kilowatt hour (kWh) for the electricity you use. RPP customers are classified as Standard Supply Service customers. RPP Prices are based on a 12-month forecast and are designed to provide stable and predictable electricity pricing, as well as ensure that the price consumers pay reflects the price Electricity to electricity generators. The Ontario Energy Board rates do include Global Adjustment Charges. The Ontario Energy Board reviews these electricity rates every 6 months.

 Non-Regulated Price Plan (Retailer)
Customers also have the option to purchase electricity from an electricity Retailer. If a consumer signs a retail contract, they elect to pay a fixed rate that is independent of the RPP pricing and Spot Market price. These customers will also pay the Global Adjustment in addition to the rate of their retail contract.
