This initiative explores bidding options in three areas: 1) aligning RDRR real-time bidding with FERC Order No. 831; 2) exploring RDRR Minimum Load and Minimum Load Costs; and 3) understanding if modifying the cap of RDRR discrete dispatch options would better reflect RDRR capabilities.

Outcome (Track 2): The ISO implemented, effective November 3, 2022. This project enhanced the market to better reflect Reliability Demand Response Resources’ (RDRR) operational capabilities to real-time bidding for discrete real-time bidding enhancements of Reliability Demand Response Resources (RDRRs) with the following enhancements.
• Infeasible Discrete RDRR RT Dispatch via Pmin Re-Rate
• Discrete RDRR Cap Increased from 50 MW to 100 MW

Outcome (Track 1): The ISO implemented, effective June 1, 2022, real-time bidding enhancements of Reliability Demand Response Resources (RDRRs) to align RDRR bidding rules with real-time price conditions consistent with FERC Order No. 831 by requiring that RDRRs must bid at least 95% of the hard energy bid cap ($1,900/MWh) when specific conditions are satisfied to raise the energy bid cap to $2,000/MWh. Through this initiative, the ISO has updated the bidding rules in Scheduling Infrastructure and Business Rules (SIBR) to automatically adjust the submitted RDRR bids based on the change in energy bid cap by maintaining the percentage of the bid cap originally submitted by the Scheduling Coordinator. This automatic adjustment occurs after the market close and will only apply if no action is taken by the close of each hour’s real-time market by the Scheduling Coordinator. It preserved the existing bidding structure for RDRRs when the $1,000/MWh soft energy bid cap is in place. It maintains that, in the real-time market, RDRRs are treated as emergency response resources with limited availability and are only released for dispatch when an Energy Emergency Alert Stage-2 (EEA2) notice is issued.
