Generators and transmitters are reminded to submit information for the IESO's 18-Month Outlook on or before April 7. The IESO will use this information when developing its quarterly assessments for the upcoming 18-month period. Information collected through this process enables the IESO to perform reliability assessments which are the primary tool for notifying market participants, the Ontario Energy Board, and the public about the adequacy of Ontario's generation and transmission resources.

  • Form 1230 'Generator Information Submittal Form for 18-Month Outlook’. The submissions on this form are for June 2015 and onwards.
  • Form 1484 'Plans for New or Modified Facilities Information Submittal Form for 18-Month Outlook'. This form is for both transmitters and generators.

Email the completed form(s) to forecasts.assessments@ieso.ca. For questions or concerns, please contact customer.relations@ieso.ca
