MISO Real-Time Outage Delta
MISO's hourly system-wide outage capacity, the forward figure, the real-time figure and the difference between them, in MW.
About this data
Each hourly row gives the system-wide outage capacity MISO carried forward, the outage capacity it sees in real time, and the gap between the two. It is a system aggregate. It does not identify individual generators, causes, or whether an outage was planned or forced.
What people use it for
- See whether real-time outages are running above what was expected
- Spot hours where unexpected outages added to tightness
- Add outage context to a MISO price or reserve event
