What saveONenergy incentives are available for commercial LED lighting in Ontario?

The IESO saveONenergy Retrofit Program provides incentives for commercial LED lighting upgrades in Ontario through two streams: prescriptive incentives (fixed amounts based on approved fixture and retrofit types) and custom incentives (calculated based on verified reductions in kWh and kW for more complex or larger-scale projects). GI manages the full incentive process as part of the project scope.

Clear answer

Clear answer, explained.

Incentive amounts vary based on fixture type, operating hours, project scale, and the total energy and demand reductions achieved.

GI manages the full incentive process as part of the project scope—including eligibility review, application preparation, supporting documentation, submission coordination, and final incentive payout support.


Key points

What this means in practice.

  • saveONenergy Retrofit Program provides incentives through prescriptive and custom streams
  • Prescriptive stream: fixed incentive amounts based on approved fixture and retrofit types
  • Custom stream: calculated based on verified reductions in kWh and kW for complex or large-scale projects
  • Most straightforward LED retrofits qualify under the prescriptive stream
  • Incentive amounts vary by fixture type, operating hours, project scale, and total energy and demand reductions
  • GI manages the full incentive process — eligibility review through to final incentive payout support

When this applies

Best-fit environments.

  • You are planning a commercial LED retrofit and want to understand what saveONenergy incentives apply
  • Your facility has a complex lighting system or large project scale and you want to know whether the custom stream applies
  • You want to understand whether GI manages the incentive application or whether you need to engage the program separately
  • You are building a project financial model and need to understand the incentive amount before finalising the budget
