About this data

This captures MISO's public real-time view of how demand compares with committed and available capacity, along with the reserve requirements published for the next day. Two kinds of record sit side by side, the live supply and demand picture and the next day's short-term reserve requirement, and they are read separately. It is useful for judging headroom and tightness on the MISO system.

What people use it for

  • Check MISO capacity against demand
  • See next-day reserve requirements
  • Spot tight operating conditions
