Annual Cold Weather Preparedness Survey for Generators and Transmitters

November 7, 2024

In preparation for the upcoming winter season, the IESO is conducting its annual Cold Weather Preparedness Survey with generation and transmission facilities. Extreme cold weather conditions can lead to operational challenges affecting the IESO’s capacity to operate the system reliably. The information provided through the survey will aid in preparations for achieving reliable grid operations during the approaching winter season.

The IESO is requesting owners and/or operators of generation and transmission facilities to complete this year’s survey by December 6, 2024. An email with a survey link will be sent out directly to all impacted market participants.

More information on the IESO’s Winterization Guidelines for generation and transmission facilities can be found in the IESO Winterization Guidelines Document.  Please note that the IESO is working on updating the Guideline referenced here and a new version will be posted once available.
