The MISO Market User Interface (MUI) 2.0 is designed with future performance, reliability, and usability in mind. With that being said, the start of MISO MUI 2.0 parallel operations originally scheduled for Thursday, July 1 is now scheduled for Tuesday, July 6.
Please take a minute to give your final “ready to start parallel operations” status using the MUI 2.0 Readiness App. Simply mark your organization as “On Track”.
Once parallel operations start on July 6, MISO will retire the Readiness App and instead rely on system logs to track your migration from legacy to MUI 2.0. The objective is to have 100% of Market Participants migrated to MUI 2.0 by the end of parallel operations.
Users can reach the Member Readiness App two ways:
1. Using MISO Market Portal
2. Click “Launch” on the MUI 2.0 Member Readiness tile.
2. Go directly to the application at
