Terminology Review:
 • The IMO makes a clear distinction between three different activities - each serving
   a specific need of the market:

       “Settlement”                  “Invoicing”                     “Payments”

 • Present detailed break-     • Formal presentation of         • Effect the transfer of
   down of all calculations      overall amounts owing to         funds between market
                                 and from the market              participant and the IMO
 • Confirm all settlement
                                 participants for the billing
   data used
 • Allow market participants
   to raise disagreements
   and address them
                                         Relatively low impact from the DAM
 • Apply adjustments

                    • Like many Day Ahead Markets around the region, DAM

                      place in the second settlement process only.

Consistency with current practices:
      A market participant deviating from its market schedule at the request
      of the IMO is entitled to a, “…settlement credit equal to the change in
      implied operating profits resulting from such response…..”

• DAM CMSC is a reflection of current real-time market principles:
    • unconstrained, uniform pricing
    • constrained scheduling
    • horizontal equity across all market participants with regards to physical
      constraints on the IMO-controlled grid
• The DAM design does NOT attempt to reinterpret the economic underpinning of
• Real-time CMSC will continue to be a part of the Settlement Process
• Current issues related to real-time CMSC have relevance in the DAM as well.11
