Column Descriptions

• Interval Hour-ending of the day-ahead solution in which constraint was binding (Central Time)
• GMTIntervalEnd Hour-ending of the day-ahead solution in which constraint was binding (GMT)
• Constraint Name Name of constraint provided by the Market Clearing Engine.  This is primarily the flowgate name.  If constraint is not a defined flowgate, this will be the branch name from the model.
• Constraint Type
  • FG Flowgate
  • MA Constraint identified by operator as being congested in the DA Market solution
  • MCE Constraint identified within the Market Clearing Engine and verified by Operator
• NERCID Existing defined NERCID if available
• State Binding or Breached
• Shadow Price Calculated DA Market Shadow Price for Constraint
• Monitored Facility Line or Transformer that is binding or breached in the solution (From station To station format for direction of binding)
• Contingent Facility Line or Transformer that if outaged will cause the Monitored Facility to be binding or breached in the solution. BASE corresponds to no contingent element causing the binding or breached state.
• Contingency Name Utilized for tracing a contingency name used in the DA public data files to a value used by TCR/ARR
