Load Displacement

What is Load Displacement? 

Load displacement is generation behind the meter.  In other words, generation for the purposes of reducing your electricity consumption or demand.  It can be a renewable or non-renewable energy source.  The latest Load Displacement rules can be found on the Ontario Energy Board (OEB) website.

How do I get started?

  1. Find out more about the process: Contact us and we will provide you with the technical specifications and the approval process. You should also contact the Electrical Safety Authority of Ontario (ESA), as your system must be inspected and approved by the ESA to guarantee that it is correctly connected to the grid.
  2. Investigate your alternatives for load displacement energy resources: information can be provided by energy consultants, energy organizations, advisors and suppliers.
  3. Determine the size of the generation unit that will suit your needs: use your prior bills as a starting point to tailor your system to your individual energy demand.

Greater than 10 kW to 999 kW of Generation

Small generation facilities are defined as having a capacity greater than 10kW and up to 999 kW when connected to a distribution system.  The latest Load Displacement rules can be found on the Ontario Energy Board (OEB) website.

Application Process

  1. Information Request
    • The client proposing the installation of renewable\non-renewable generation should contact London Hydro and ESA. The customer will need to visit the London Hydro website and fill out an Initial feasibility Assessment (IFA) form.  The details can be found in the important documents section.
  2. Provision of Information 
    • London Hydro will provide information regarding the connection process, approvals required, technical requirements, contractual requirements and application forms.
  3. Customer Develops a Plan
    • The customer reviews the information provided by London Hydro and ESA and develops an installation plan. Such a plan shall include the size and type of generator, and a plan outlining who will need to be included and when. The customer will prepare detailed engineering drawings, submit all the plans to ESA for approval, and submit information to London Hydro for design review. It is recommended that the design is provided to London Hydro within 30 days. 
  4. Connection Impact Assessment
    • The customer submits for a connection impact assessment by London Hydro to be conducted for the chosen location. Information required includes the size of the generation facility; the type of generation facility; type and details of technology; fuel type; single line diagram; location; protection philosophy; and preliminary design of proposed interface protection. London Hydro performs the connection impact assessment of the proposed generation on the distribution system. A Study agreement will be sent to the customer detailing requirements and cost.
    • A Hydro One Connection Impact Assessment (CIA) will be performed, if required.
