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.
