With the DAM prices also identified in the DAM results, participants simply access the PTP Obligations that cleared at an identified source-sink pair and multiply that volume by the price differences of the Day Ahead Settlement Point Price (DASPP) between the source and sink. This provides the pre-settlement result that can be compared to the result posted on the DAM settlement statement for shadow settlement purposes. Day-Ahead Energy Revenue Description Day-Ahead Energy Revenue (DAEREV) is not a charge type, but rather a key global bill determinant. This bill determinant is used by multiple charge types and intermediate calculations such as the Day-Ahead Make-Whole Payment and the RMR Day Ahead Energy Revenue Total calculation. DAEREV should be calculated for all RMR and non-RMR Resources with a Day-Ahead Energy Sale. Calculation Calculate the Day-Ahead Energy Revenue by QSE, Resource, and Settlement Point, for each Operating Hour of the Operating Day.
