Provides a summary of monthly cost of congestion for each binding constraint in the DA Market.  Posting is updated on the first day of the month for the previous month.

Column Descriptions

• Date The year and month for which the data corresponds in YYYYMM format
• 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.
• Monitored Facility Line or Transformer that makes up the corresponding constraint (From station To station format for direction of binding)
• Contingent Facility Line or Transformer that if outaged, caused the Monitored Facility to be binding or breached in the solution.  BASE corresponds to no contingent element.
• Contingency Name Utilized for tracing a contingency name used in the DA public data files to a value used by TCR/ARR
• Sum The calculation of the total impact of congestion for the month.
  • This is calculated by summing up the following equation for each operating interval in the month
  • Flow Amount (in MW) * Constraint Shadow Price
