Congestion By Constraint

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.
  • Sum The calculation of the total impact of congestion for the month. 
  •             o   This is calculated by summing up the following equation for each operating interval in the month:
  •                       Flow Amount (in MW) * Constraint Shadow Price
