 MISO generates a separate daily settlement statement for each Asset Owner (AO) or each Market Participant (MP).  An MP may request a subaccount(s) to track trades from different traders, differentiate a single load from another load or differentiate generator activity by completing the proper registration documentation.

A Market Participant that wishes to add additional AO’s, may do so, up to eight times per year,  in accordance with the Commercial Model update schedule.  All separate daily settlements for each AO roll up to a single invoice per MP weekly.
