Preliminary Release Plan for Changes to IESO IT Systems Posted for Review

February 17, 2022

The market-facing preliminary release plan, posted under R47.1 of the IT Release Schedule, includes three changes:

- As part of the Improving Accessibility of Operating Reserve Project, Online IESO is being updated to provide a feature to capture Operational Compliance Aggregation details from Market Participants.

- Changes to the Capacity Auction Reports - pre and post-auction reports will be amended to reflect enhancements that have been incorporated into the 2022 capacity auction.

- The IESO is preparing to upgrade its current Supervisory Control and Data Acquisition (SCADA)/Emergency Management Systems to a newer version in 2022.

More information on these changes is available in the preliminary release plan. Feedback on the plan is due by March 2, 2022. Comments can be sent to pending.changes@ieso.ca.
