Load Displacement

What is Load Displacement? 

The Load Displacement initiative may be used by electricity consumers in Ontario who generates some of their own energy from a renewable or non-renewable resource. Load displacement enables you to displace up to 100% of you site load.

How do I get started?

  1. Find out more about the process: Contact us and we will provide you with the technical specifications, the approval process and how to get your Load displacement project connected. 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. 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 demands.

 

If you have any questions regarding the Load Displacement initiative, please contact London Hydro's Generation Team:
