Review of the IMDC Process

The IESO is looking for stakeholder feedback to help shape an internal review of the Interim Market Document Change (IMDC) Process. The IMDC process is part of the baseline process. It is used to introduce a change to a market facing document (e.g. market manuals) between two baseline publication dates.

The IESO encourages all stakeholders and market participants with involvement in the market manuals process to participate in this engagement.
