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. 


Annual Conservation Results Report

In 2015, Ontarians achieved 1.3 TWh of energy savings, representing 15 per cent of the total 8.7 TWh target to be achieved by 2020 through the Save on Energy and Industrial Accelerator Programs.  These programs were delivered at a cost of under four cents per kWh, providing the most cost-effective resource to meet the province’s long-term energy needs, as well as opportunities for consumers to take advantage of the many benefits of energy efficiency.

Quarterly 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.  ​   

Third Quarter 2016

Preliminary Q3 2016 results indicate 46,177 megawatt-hours (MWh) net energy savings from LDC-delivered and non-LDC delivered programs, and 190,919 kilowatts (kW) of net peak demand savings were achieved.

Highlights of Q3 include:  

  • The development of two new province-wide programs initiated as part of the June 10, 2016 Ministry Directive: Energy Performance Program for Multi-Site Customers and a Whole Home Pilot Program for residential customers.  

  • The Achievable Potential Study (posted on July 4, 2016) to help inform the Conservation First Framework (CFF) mid-term review and electricity efficiency planning and programs in Ontario.

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.
