Save on Energy

About the Retrofit program

Everything you need to know to get started on your project.

Under the Retrofit program, there are two types of project applications available: the prescriptive and custom track.

Prescriptive track

Prescriptive track applications are ideal for quick system upgrades. Incentive levels are based on a predefined amount with applications that are easy to follow and have a fast turnaround.

Incentive amounts for lighting and other measures (which include lighting controls) are per unit of product.

To participate, your project must be pre-approved. Small projects must be worth a minimum incentive of $500.

Custom track

Custom track applications are designed to provide flexibility for more comprehensive projects, with opportunities for increased energy savings. Incentives are based on energy savings over pre-project baselines. All custom track incentives are capped at 50 per cent of project cost.

The incentives are based on the specific information you provide about your project, which may include:

  • A description of the facility baseline electricity use
  • A description of the equipment being replaced
  • A description of the new equipment to be installed 
  • The operating schedule (days per week, hours per day, time of day)
  • The total cost of the retrofit, including equipment, labour and disposal costs
Available incentives
Lighting The greater of either $400/kW of demand savings


$0.05/kWh of first-year electricity savings
Other measures, including lighting controls, building automation systems, water chillers and cooling towers The greater of either $800/kW


$0.10/kWh of first-year electricity savings
Multi-family – tenant education $200/kW of the estimated demand savings, and to a maximum of 10 per cent of the incentives paid for the equipment replacement project
Social housing Advance 50 per cent of eligible financial incentive funding before project starts and after project approval by the IESO

Gap grant funding: double the participant incentive, capped at 50 per cent of the project cost

To participate, your project must be pre-approved. For the custom track application, your project must be worth a minimum incentive of $1500.

All custom track incentives are capped at 50 per cent of project cost. Projects must also deliver energy savings for at least 48 months.

    • increased insulation, and installation of high-performance windows and frames
    • low-emissivity window glazing
    • low-emissivity roof barriers
  • implementation of new operating procedures required either to obtain or increase the effectiveness of an energy management system or building automation system, including the installation of equipment such as:
    • an energy management system
