Pending Changes - Documents

The list below provides advance notice of pending changes to the market rules, market manuals, technical interfaces documentation or other items that define the operation of the IESO-administered market. For changes that are minor, the listing will identify the document that is changing and a description of the revisions, but a link to the altered document may not be included.

Comments on the design and implementation concerns can be sent to pending.changes@ieso.ca. This feedback will be taken into account during the baseline schedule.

Details of all of the documents being revised for the current Baseline (and the next Baseline if available) can be found below.
