Urgent:	Yes
Sections:	6.9.2.1
Description:	This PRR corrects discrepancies in the Replacement Reserve Under-Scheduled Capacity charge equation.
Reason:	PRR 666, Modification of RPRS Under-Scheduled Capacity Charge Calculation (approved by the Board on July 18, 2006), was finalized after many iterations and discussions regarding modification of the Replacement Under-Schedule Capacity charge calculation. Some of these modifications contributed to discrepancies in the description of the Net Load position and mismatch components of the equation.
