Electricity Updates

Before you submit your bid for the Ontario government's RFP, you must complete Pre-Bid work with Hydro One. The steps involved in the Pre-Bid process with Hydro One vary slightly, depending on whether you plan for your project to connect with Hydro One's transmission or distribution system. This section will help you determine what you need to do to submit your bid. You'll find information on:

The expedited process shown applies to both the 200 MW and the 1000 MW RFPs.

  Hydro One Connection Process

Deciding whether your project is connected through our transmission or our distribution system depends on a number of factors such as the type and availability of nearby facilities. Generally, the higher the voltage of the system, the more generation capacity can be connected to it.

Transmission facilities operate at voltages above 50 kilovolts (kV).

Transmission lines are not as plentiful as the distribution lines. See map of Ontario's transmission lines.

For a transmission-connected facility, generators must have Hydro One conduct a Transmission Customer Impact Assessment as well as a System Impact Assessment conducted by the Independent Electricity System Operator (IESO).

 
     

Distribution facilities operate at voltages of 50 kV or less.

For a distribution-connected facility, a Distribution Connection Impact Assessment is required to assess the impacts on the electricity system. If the proposed generating capacity is 10 MVA or greater, a Transmission Customer Impact Assessment must be completed by Hydro One and a System Impact Assessment must be completed by the IESO as well.
