Through this initiative the ISO will evaluate the following two topics: (1) whether commitment proxy costs, generated bids, and default energy bids allow scheduling coordinators to accurately reflect and recover their generators’ unit-specific marginal costs; and (2) whether changes to the economic bidding of commitment costs and associated market power mitigation methodology could increase market benefits when bidding under competitive market dynamics.
Outcome: This initiative enhanced the ISO market rules to support Bidding Flexibility and comply with FERC Order No. 831 by incentivizing flexible resource participation during times of tight fuel supply, accounting for costs of flexible resources (gas and non-gas) to reduce risk of insufficient cost recovery, encouraging participation of non- Resource Adequacy and voluntary EIM resources, and by requiring support for verified costs of energy bids above $1,000/MWh.
