Utilities in the Western Interconnection have traditionally allocated contract path rights for the use of the transmission systems they own or operate.  These rights are defined based on the specific facilities over which energy is assumed to flow.

By way of contrast, the actual flow on the system is dictated by the physical characteristics of the transmission system and not the contract.  This leads to a mismatch between the actual flows and the assumed flows. 

The benefits of implementing a flow based scheduling and its related processes may generally include more accurate utilization of transmission facilities, a truer signal of congestion on specific lines, and greater utilization of the grid.

The goals of the Flow Based Market Investigation Work Group are:

  • Investigate tools available to implement flow based scheduling in the WestConnect footprint.
  • Assess the costs and benefits of the implementation of various solutions.
  • Recommend solutions if practical.
