Energy-Efficiency Resources and Reports

Find below key resources and archived information from the previous Conservation First Framework (CFF). 


Energy-Efficiency Reporting

The IESO publishes annual and quarterly energy-efficiency reports that highlight the energy and peak demand savings of energy-efficiency programs. The most recent reports are accessible from the links below.

Annual reports

Quarterly reports

Annual and quarterly reports from 2018 and earlier can be obtained by sending a request to saveonenergy@ieso.ca and advising whether the report(s) need to be provided in an accessible format. Please allow a minimum of one business day for a response.


2019 Achievable Potential Study

The 2019 Achievable Potential Study (APS) identifies and quantifies energy (electricity and natural gas) and demand savings, greenhouse gas emissions reductions and associated costs from energy-efficiency measures for the period of 2019-2038.

As the first integrated achievable potential study in Ontario, the 2019 APS captures the dynamic relationship between electricity and natural gas use to better support emerging whole home and business energy-efficiency measures and programs. The 2019 APS will be used to inform the development of future energy-efficiency frameworks; program design, implementation and evaluations; and long-term energy resource planning.

Additional details on the 2019 APS stakeholder engagement process are available on the on the APS engagement webpage.

2016 Achievable Potential Study

The Achievable Potential Study provides an estimate of the short-term electricity conservation potential that is achievable within the time frame of the CFF as well over a 20-year horizon for the province and each LDC.

For more information please visit the Achievable Potential stakeholder engagement webpage.
