If you are building or renovating a business in the City of Thunder Bay and require a new or upgraded service, the process you follow depends on the size of the service you are having installed.
If your service is to be less that 200 Amps, you follow the same six steps as a residential customer.
If your service is to be 3Ø 200-amps or greater and 1Ø greater than 200-amps, the following 12 steps need to be completed for this process:
As a first step, we recommend you read the Thunder Bay Hydro Conditions of Service. Print copies are also available at our Power Systems building, located at 37 Front Street.
Set up an appointment with a Distribution Designer to discuss the requirements of your new or upgraded electrical service and where it should be located. Call our Engineering Services Department at 343-1168 to make arrangements.
The Designer will require you to provide the information listed on the Service Information Sheet (formerly the Transformer Information Sheet). Information required will include, but not be limited to:
Note that customers requesting a service over 50kW are required to install interval metering. A telephone line must be supplied to the meter base at the owner's expense before the service is energized. If the telephone line can not be installed before Thunder Bay Hydro energizes the service, additional charges to manually read the meter once a week until the telephone line is installed will be added to the cost of the job and will be reflected when the true-up of costs has been completed.
Once you have provided all information deemed necessary by the Designer, we will proceed with reviewing your electrical service.
After reviewing all your information and finding the details acceptable, the Designer will complete a Thunder Bay Hydro Estimate to Connect Overhead & Underground Distribution form or a" Thunder Bay Hydro Estimate to Connect Commercial Customers and Customers Over 200 Amp" form. This document will include the estimated cost of the labour and materials supplied by Thunder Bay Hydro to install/upgrade the service. The Estimate to Connect can be directed to the property owner or an authorized representative for the property owner.
This Estimate to Connect must be paid in full before Thunder Bay Hydro can proceed with any work. Once the work is completed, a 'true-up' will be completed and the customer will be billed for actual costs.
After the Estimate to Connect is issued:
The invoice, based on the Estimate to Connect, will need to be paid in full before Thunder Bay Hydro can proceed with any work on the electrical service. Payment can be made two ways:
*no telephone credit card payments will be accepted.
If, after the Estimate to Connect is issued, you require changes to the work to be done by Thunder Bay Hydro, the actual costs to revise the drawing will be charged to the customer and will be reflected in the true-up when the work is completed.
Either you or the contractor doing the electrical work must contact the Electrical Safety Authority (ESA) at 1-877-372-7233 to obtain an electrical permit.
Three preliminary inspections and one final inspection must be performed by Thunder Bay Hydro. These are separate from the ESA inspection, which is also required. It is recommended that you request the Thunder Bay Hydro preliminary and final inspections before the ESA inspection to avoid having to request ESA re-inspection should Thunder Bay Hydro require modifications.
The cost of one ground resistance reading test is included in the amount quoted on the Estimate to Connect. If ground resistance testing results in readings over the maximum 8 ohms, actual costs for each additional test required until the readings are at or below 8 ohms will be added to the cost of the job and will be reflected when the true-up of costs has been completed.
When the contractor has completed the electrical service you or your authorized representative must notify the Designer that the electrical service is available for Thunder Bay Hydro final inspection. Both Thunder Bay Hydro and ESA inspections need to be completed satisfactorily and payment must be received in full before we will be able to connect/reconnect the new or upgraded service. Note that the cost for additional inspections by the Designer or any additional work that is required by Thunder Bay Hydro staff will be added to the cost of the job and reflected in the true-up.
If this is a new service, you will need to set up an account at our Customer Accounts Department, located on the main floor at 34 N. Cumberland Street. Call 343-1111 for more information.
When the electrical work is complete and has been approved by Thunder Bay Hydro, contact the ESA to arrange for an inspection.
When the ESA Inspector's authorization is received, our Customer Accounts Department will prepare a service connection order for each meter. These orders are forwarded to our Engineering Services Department. Once Thunder Bay Hydro has completed the necessary line work and the inspection has been completed and approved, the new or upgraded service will be connected within 10 working days
