Information on DACP Settlement Charges

The day-ahead commitment process (DACP) introduced new settlement charges to market participants in 2006. The DACP was modified in October 2011 resulting in settlement changes. The first settlement statement for new DACP was issued on October 27, 2011 for trade date October 13, 2011. Based on the type of market participant, here is a list of the new or modified DACP charge types and their descriptions that you may see on your settlement statements.
