2019 Conservation Achievable Potential Study

The IESO and the Ontario Energy Board (OEB) will be conducting an integrated electricity and natural gas conservation achievable potential study (APS) to be completed by June 2019. The main objective of the APS is to identify and quantify energy savings (electricity and natural gas), GHG emission reductions and associated costs from demand side resources for the period from 2019-2038. Additional details on the APS including background, objectives, outputs and governance can be found in the Project Charter and Engagement Plan.

To support this project, an APS Advisory Group will be established to help develop the study. The terms of reference are intended to provide guidelines for the Advisory Group.

For any questions on the 2019 APS engagement, please contact engagement@ieso.ca.
