About this data
Each row is one hour with the number of real-time transmission constraints that were binding in MISO. It supports system-level analysis of how frequent congestion is. It names no facility, contingency or shadow price, so it cannot say which constraint caused a given episode.
What people use it for
- Track how often MISO congestion occurs by hour
- Compare congestion frequency across seasons
- Spot hours with unusually many binding constraints
