    Market Participant Notification

    We are discontinuing the practice of sending notification letters directly to market participants to communicate the impacts of new connections in their area. Instead, for projects in the Cluster Assessment Process, we will refer market participants to regional congestion assessment reports via the AESO stakeholder newsletter and website.
