BPM changes that mirror changes to Tariff section 27.4.3.2.1 to update Scheduling parameters, or penalty prices, which are used to determine when the SCUC and SCED software will relax an enforced Transmission Constraint rather than adjust Supply or Demand bids or Non-priced Quantities as specified in Sections 31.3.1.3, 31.4 and 34.12 to relieve Congestion on the constrained facility.
This BPM changes align with the changes proposed in the Adjustment to intertie penalty prices policy initiative. The objective is to ensure the market does not overschedule interties in RUC or RTM. Additional penalty prices are also changed in RTM to preserve the relative scheduling priority in the market optimization
