Industrial Energy Efficiency Program

Transform your industrial process with incentives for energy-efficiency improvements

What is the Save on Energy Industrial Energy Efficiency Program?

The IESO’s Save on Energy Industrial Energy Efficiency Program (IEEP) supports industrial customers across Ontario in improving their industrial processes and implementing system optimization projects. The program offers organizations up to $5 million in financial incentives for each large, complex industrial energy-efficiency project accepted into the program. Eligible projects will deliver electricity savings using proven commercial technologies to lower energy consumption and reduce electricity bills.

How does the program work?

IEEP provides overall total funding of nearly $80 million to qualifying industrial participants over two competitive rounds of funding to be initiated in 2022 and 2023 respectively. In each round, participant applications will be ranked on the electricity savings their projects can achieve cost effectively, among other criteria. The organizations with the highest-ranked applications will be eligible to receive funding for their project(s).

Round 1 offers participants up to $5 million per project in incentives. Round 1 opened on April 11, 2022 and will close on September 30, 2022. The application process has two stages.

  • In Stage 1, participants must submit their application detailing their proposed project(s) online by August 15, 2022. The IESO will review the applications and make a preliminary assessment of eligibility.
  • Participants whose applications are deemed eligible will be invited to submit a Stage 2 application, which must include a further detailed project proposal, budget and a Measurement and Verification (M&V) Plan.
  • Stage 2 applications must be submitted between September 1, 2022 and September 30, 2022 after which time the IESO will use the criteria detailed to assess and rank applications.
  • The IESO expects to notify successful applicants in Q4 2022. The timing of the notification from the IESO will depend on the quality of applications and the number received.

Participants with successful applications must have their project(s) in service within three years of the contract date or by December 31, 2026, whichever is earlier.

Round 2 opens for applications October 1, 2022 and closes on August 15, 2023. Funding for Round 2 projects will be awarded in late 2023.

Who is eligible?

Participants must be:

  • Owners and/or operators of an industrial facility located in Ontario, or
  • Third-party applicants with the authority to implement a project at an industrial facility located in Ontario.

Projects must:

  • Involve an energy-efficiency improvement applied to, or in support of, an industrial process
  • Propose a minimum electricity savings of 2,000 MWh per year (which must represent a reduction of at least 15 per cent of the baseline electricity use of the relevant industrial process)
  • Use technology that is commercially available and not excluded by the program eligibility rules.

Note: Please refer to the Evaluation Criteria and in the Key Program Documents section.
