Hydro Ottawa is responsible for the safe, reliable delivery of electricity to more than 353,000 customers in the City of Ottawa and the village of Casselman. Hydro Ottawa is committed to delivering value to its customers by providing safe and reliable service.

The Delivery Charge covers the costs of delivering electricity from generating stations across Ontario and then to your home or business. It includes the costs to build and maintain transmission and distribution lines, towers and poles and to operate provincial and local electricity systems. Hydro Ottawa’s distribution charge, which is included in the delivery charge, represents only a small portion of your bill.

We pass on the remaining charges, without mark-up, to the other companies responsible for generating electricity, transmitting it, and to regulators and the provincial government. A portion of these charges are fixed and do not change from month to month. The rest are variable and increase or decrease depending on the amount of electricity that you use. Please see the chart below for a break-down of these charges.*
