Planning Outlook

Forecasting and Planning

The IESO is launching a new engagement initiative on the development of a Planning Outlook. The Planning Outlook is part of our efforts to build transparency into our planning processes by providing updated information to the market to enable more informed decisions. There will be opportunities in the engagement to provide feedback on components of the planning outlook and for the sector to learn more about IESO planning processes.


The development of the outlook will include more public touchpoints by providing updated information to the market and regularly engaging with stakeholders to enable them to make more informed decisions and investments. In support of the objective of transparency, this engagement initiative will provide interested parties with an opportunity to provide feedback about specific components of the outlook and to receive more information about IESO planning processes.

All enquiries, comments and nominations can be directed to
