The California ISO is deploying the functionality of its Reliability Demand Response Resource (RDRR) Bidding Enhancements Phase 1 initiative, effective trade date June 1, 2022.
The functionality being implemented enhances real-time bidding for the RDRR model by aligning RDRR bidding rules consistent with FERC Order No. 831, including the following functionality:
- RDRRs must bid at least 95% of the hard energy bid cap when the conditions are satisfied to raise the soft energy bid cap without requiring additional cost-justification to substantiate their bids.
- If the energy bid cap is raised and no action is taken by the Scheduling Coordinator to revise their RDRR bid(s) to 95% of the hard energy bid cap, ISO systems will automatically revise the RDRR bid(s) to the equivalent percentage of the raised energy bid cap value as was submitted relative to the initial energy bid cap value. This logic also holds in the event that the energy bid cap is lowered.
Additional information on the new RDRR Bidding Enhancements Phase 1 functionality is detailed in a revised version of the Business Practice Manual (BPM) for Market Instruments. The Proposed Revision Request (PRR) detailing these edits, PRR 1434, is available on the ISO’s Business Practice Manual Change Management website.
