About the Retrofit Program
We help businesses by providing financial incentives to upgrade to more energy-efficient equipment that can reduce energy bills, lower carbon footprints and enhance staff comfort.
Projects that achieve sustainable, measurable reductions in electricity use may be eligible for the Save on Energy Retrofit Program.
Prescriptive vs. Custom
The Retrofit Program offers two incentive streams: Prescriptive for common upgrades with set incentives, and Custom for complex projects where incentives are calculated based on actual operating conditions.
Prescriptive Stream
This stream helps businesses earn set incentives for common, proven energy upgrades. You can choose upgrades from a convenient list of eligible measures with defined incentives—up to 50% of eligible project costs.
Custom Stream
This stream supports businesses undertaking complex or unique energy-efficient retrofits that may not fit in the Prescriptive Stream and project savings vary based on specific facility conditions. Incentives are calculated from verified kWh or kW peak reductions—up to 50% of eligible project costs.
Bonus offer for electricity-constrained areas
Receive double the incentive rate for most non-lighting projects in eligible areas, capped at 50% of the eligible project costs.
How it works
No matter which Retrofit stream you choose, Prescriptive or Custom, the application steps will be the same. Our guided process takes you from sign-up to incentive payment with ease.
