Adjustment to Intertie Constraint Penalty Prices Initiative: Deployment Effective Trade Date 6/1/22
MESSAGE

The California ISO is deploying the changes proposed in the Adjustment to Intertie Constraint Penalty Prices initiative, effective trade date June 1, 2022 for both Day-Ahead and Real-Time markets.

 

The objective of this change is to ensure the market does not overschedule interties in the Day-Ahead Residual Unit Commitment (RUC) process or the Real Time Market (RTM). Additional penalty prices are also changed in the RTM to preserve the relative scheduling priority in the market optimization.

 

Additional information on the new penalty prices is detailed in Section 6.6.5 of the Business Practice Manual for Market Operations. Proposed Revision Request (PRR) 1411, detailing these changes, is available on the ISO’s Business Practice Manual Change Management website.

 

More information on this initiative is available at the following:
