Reason For Revision

CAISO believes that under normal operating conditions it continues to be appropriate to clear hourly block imports and exports in the Hour-Ahead Scheduling Process Uplift and settle them at FMM prices without provisions for a make-whole payment to bid price.  During very tight system conditions, the benefits of provisions for an import bid make-whole payment likely exceed the drawbacks. Consequently, the CAISO proposes provisions for bid cost make-whole payments for real-time market hourly block economic imports during tight system conditions.

The CAISO proposes that the imports eligible for a bid make-whole payment include:

 

·         Real-time market incremental energy that are incremental to any import amount scheduled in the day-ahead market.

·         Real-time market incremental energy that are the result of an export scheduled in the day-ahead market and reduced by the real-time market.

 

The effective date of the changes is 6/1/2021 and the anticipated implementation date is 6/29/2021
