The opening flow uses Constellation's directly reported RNF metric rather than gross operating revenue because purchased power and fuel are commodity pass-through inputs. This prevents the $6,352M procurement stream from obscuring the value retained by the generation and customer businesses.
Labels and narrative explain the filing. A category marked “arithmetic bridge” or “residual” is calculated from reported totals, rather than a separately reported line.
