Incoming Changes to the Save on Energy Retrofit Program - Effective June 30
June 5, 2025
Enhancements are coming to the Save on Energy Retrofit program as part of the IESO’s long-term strategy to deliver enduring, impactful energy efficiency solutions for Ontario businesses.
Key program updates include:
- Increased incentive rates for the Custom stream
- Raised threshold at which measurement and verification, and additional engineering calculations are required for Custom projects
- New Prescriptive data centre measures
- Updated list of local areas qualifying for regional adders, enabling participation in new areas
- Revised incentives for greenhouse lighting
These program changes reflect feedback from Save on Energy participants and delivery partners and build on enhancements introduced earlier this year, which included the province-wide launch of Solar PV incentives.
