Most lighting measures previously available as part of the Retrofit program are now offered through the Save on Energy Instant Discounts Program. Please visit the Instant Discounts Program page for more information.
The Retrofit program will release semi-annual updates each spring and fall. As part of these updates, new measures and incentives are being added to the Retrofit program to enable businesses to continue to save on energy costs and to take advantage of a variety of technologies and products to help improve the overall operations of buildings and facilities.
Below is the list of Prescriptive measures and incentives currently available under the Retrofit program. For more complex energy-efficiency projects, the Custom stream offers incentives at a rate of $1,800/kW or $0.20/kWh, whichever is higher, up to 50% of eligible project costs.
The incentives listed below are the maximum amounts offered. The actual amounts paid will depend on specific program requirements, including equipment size and eligible cost caps.
Note: This list has been updated to reflect changes made to the Retrofit program effective June 30, 2025.
