Conservation Overview

Conservation is a cost-effective and reliable resource. For each dollar invested in energy efficiency, about two dollars are saved in avoided generation.

The Independent Electricity System Operator (IESO) oversees the province’s electricity conservation
and demand response programs, supporting the delivery of programs to residential, business, and
industrial customers by local distribution companies’ (LDCs), and offering programs directly to the
transmission-connected customers of Ontario. 


Conservation Progress Report

The Progress Report highlights the results of conservation programs by quarter, including savings for residential, business, and industrial programs, and the number of program participants. Fourth quarter
reports also detail savings results and program participation totals for the entire year.  ​   

Second Quarter 2016

Preliminary Q2 2016 results indicate 149 gigawatt-hours (GWh) net energy savings from LDC-delivered and non-LDC delivered programs, and 203 megawatts (MW) of net peak demand savings were achieved.

Analysis of Ontario’s Full Scale Roll-out of Time-of-Use (TOU) Rates - 2014

This report presents the findings from the third and final year of a study examining the impacts of TOU rates from their inception through to the end of 2014. This evaluation was part of a multi-year study to determine the impact of TOU prices in Ontario.

View the analysis reports from the first year (2012) and second year (2013) of the study. 


Conservation Results 2011-2014

The IESO works collaboratively with local distribution companies and other partners to deliver conservation programs to ensure residents, businesses, hospitals, schools and others have access to tools to better manage their electricity use. The Conservation Results Report highlights the outcomes from Ontario’s energy saving and demand management programs and other conservation activities. Between 2011 and 2014, energy savings from saveONenergy programs exceeded the provincial target, achieving 6,553 GWh of electricity savings.
