Evaluation, Measurement and Verification

Documents referenced on this page, but not posted, can be obtained by contacting saveonenergy@ieso.ca with a link to the web page that lists the document and advise whether it needs to be provided in an accessible format. Please allow a minimum of one business day for a response.

To ensure that Save on Energy programs achieve their intended goals, provide value for ratepayers and identify opportunities for continuous improvement, the IESO regularly measures electricity savings and demand reductions from each program in market. Program evaluations generally include market assessments, process evaluations, retrospective outcome/impact assessments and cost-benefit evaluations as per the IESO Cost-Effectiveness Guide and IESO Cost-Effectiveness Tool.

Please refer to the IESO CE Tool User Guide for step-by-step instructions on how to use the IESO CE Tool.

EM&V Protocol (v4.0)

The IESO recently updated its industry-leading Evaluation, Measurement and Verification (EM&V) Protocol. This is the most significant update to the protocol since it was first released more than 10 years ago. The IESO has been an industry leader in EM&V since Ontario began delivering energy-efficiency programs in 2007.

 

The EM&V Protocol is used by program evaluators and program administrators to ensure conservation and demand management programs achieve their intended goals, to enable the development of verified energy and demand savings results and to facilitate adjustments to programs.

 

The updates include new and revised evaluation methodologies, concepts covering new types of energy-efficiency programming, and it boasts a streamlined, easy-to-read structure.

 

The evaluation reports below are produced in accordance with the IESO EM&V Protocol  and present energy and demand savings, as well as, recommendations for program improvements. Responses to the recommendations for program improvements are also available on this web site.

Evaluation Reports

Evaluation reports for the 2020 program year show that the programs delivered during the Interim Framework, which ran from April 1, 2019, to December 31, 2020,  produced cost-effective savings of 302 GWh and 55 MW persisting to 2022. Evaluation processes provide confidence that energy efficiency is a reliable resource for system planning that persists on average for more than 10 years. At less than two cents per kilowatt-hour, energy efficiency is also a cost-effective energy resource for Ontario.
