As of April 1, 2019, energy conservation programs in Ontario are changing. The Independent Electricity System Operators (IESO) will manage all conservation programs in the province moving forward. For more information, please visit Hydro One’s Saving Money and Energy page and the IESO’s Energy Efficiency for Business and Industry page.
The Ontario Government recently held public consultations on Industrial Electricity Prices. The government also plans to hold sector-specific consultation sessions with key industries. More information can be found at www.ontario.ca/page/consultations-directory.
Hydro One is dedicated to working with you to meet all of your electrical needs. Whether you are looking for a small business, commercial or industrial connection, the steps below outline the connection process and provide information on what we will do, as well as what you will need to do each step of the way.
In addition to the process outlined below, we also have several resources that will be helpful in planning for your electrical connection.
There are multiple phases in the process to connect to our electricity grid. Click the jump links below for details on each phase:

There are five organizations - including the customer - who work together to create new connections to our electricity network.
Electricity consumer. Builds and connects facilities to the electrical grid.
Licensed transmission and distribution utility. Responsible for operating and maintaining the transmission and distribution systems, including new connections once approved. Physically connects your facility and ensures safety.
The Independent Electricity System Operator (IESO) manages supply and demand of electricity. Directs flow of electricity across Ontario. Manages conservation and energy-saving programs.
The Ontario Energy Board (OEB) regulates electricity utilities in Ontario, including cost responsibility and electricity rates (Transmission System Code and Distribution System Code).
The Electrical Safety Authority (ESA) is mandated to enhance public electrical safety in Ontario. The ESA must provide authorization in order for a customer to connect to the system.
In order for us to assess your needs, we’ll need some information from you upfront.
Contact Hydro One to initiate your connection:
For all connection requests, please call us at 1-888-664-9376 or complete the online form
At a high level, we will need the following:
Project location
Estimated amount of power
Description of your connection and/or business.
Review your information and schedule an initial meeting to discuss your project and the connection process
Depending on your project size, we may request more project details via the New Customer Connection Information (NCCI) form.
In this phase, we’ll review your project information and determine what work is required to get you connected.
Submit your project details and NCCI form (if applicable)
Submit all supporting documents with your application, including Single Line Diagram and Primary Fusing information
Sign off on estimate package and provide payment for Design (if applicable).
Review your connection application to determine the best option to accommodate your connection
Meet you on-site if required
Identify any line expansion, upgrades or IESO studies required
Perform load and motor analysis to ensure you have the power you need
Depending on your project specifics and line expansion requirements, a Class C Estimate may be prepared along with an estimate package for review and acceptance.
Delivering the electricity you need safely requires planning. In this phase, we will design your connection, refine our cost estimate and secure all necessary permits and approvals. If a line expansion is required to accommodate your connection, you will need to pay a staking fee to proceed.
Work with us to determine a target in-service date.
Assign a designer to your project
Create a detailed design for your connection

For any distribution connections over 10 MW
What to expect on your electricity bill once you connect
Hydro One has a three-phase process for distribution connections to our grid. Get details for each phase below:
The Electrical Safety Authority (ESA) is mandated to enhance public electrical safety in Ontario. The ESA must provide authorization in order for a customer to connect to the system.
If you are a small- or medium-sized business (over 50 kW monthly demand), please call us at 1-888-664-9376 or complete the online form
If you are a large business with transformation/nameplate capacity greater than or equal to 2 MVA, please complete the Large Customer Contact Form.
A Hydro One representative will schedule an initial customer meeting to discuss your project, the connection process and information needed to get things started
You will be asked to complete a New Customer Connection Information (NCCI) form.
Hydro One’s team will review your connection application to determine whether there is capacity to accommodate your connection and whether any expansion work is required
If a line expansion is required, you will receive a staking fee letter and be asked to provide payment
Hydro One’s team will complete necessary engineering design work and provide a cost estimate
If you wish to proceed, you will enter into a contract with Hydro One and be asked to provide payment.
Note: Depending on the complexity and size of your connection (typically >10 MW), the IESO may need to perform a System Impact Assessment (SIA)
You must schedule and complete an Electrical Safety Authority inspection and provide documentation to Hydro One
Once ESA authorization is received, Hydro One will conduct a final inspection and complete your connection
If you are a registered market participant with the IESO, you will need to enter into a Distribution Connection Agreement with Hydro One.
Depending on the size and scope of your project, approvals may be required throughout the process and could have a significant impact on project timelines. They can include, but are not limited to:
Environmental approvals to construct facilities on environmentally sensitive lands
Municipal approvals and permits, including land easements and land acquisitions
Sufficient capacity available or the need for future expansion.
