Reason For Revision
Market Participant created a dispute where they identified an issue with their load following resources getting SPIN dispatches outside contingency intervals.  During incidences like these, the energy quantity associated with the SPIN/NSPIN dispatch is not being accounted for when calculating their ISO dispatched energy.

 

To fix this issue, we updated equation in the Meteterd Subsystem (MSS) Deviation Penalty Pre-Calc.
