Bid cost recovery and variable energy resource settlementsThe initiative explores ISO tariff solutions for settling residual imbalance energy for economically bidding variable energy resources and the persistent deviation metric broadly applied to variable energy resources. Additionally, the initiative presents refinements to the day-ahead metered energy adjustment factor. Please see the associated market issues bulletin describing residual imbalance energy settlement and ramp rate changes.
Bid cost recovery enhancementsThis initiative explores potential market design changes to the real-time and day-ahead bid cost uplift allocations and bid cost recovery for units operating across multiple days. (Formerly Two-tier allocation of real-time bid cost recovery)
Bid cost recovery mitigation measuresIn December 2011, as part of Renewables Integration Market and Product Review Phase 1 initiative, the Board approved separating the day-ahead and real-time bid cost recovery calculations. Through this initiative we will design and implement a performance metric and a check for persistent uninstructed imbalances in the bid cost recovery calculation to mitigate any adverse effects.
Bidding and mitigation of commitment costsShortly after the launch of its new market in April 2009, the California ISO undertook a two-phased approach for changing start-up and minimum load bidding restrictions in order to alleviate the excessive cycling of generating resources and to help generators recoup their commitment costs. Phase 1, implemented in July 2009, enabled generation owners to modify their start-up and minimum load elections and to switch between the registered and proxy cost options more frequently. Phase 2 was initially proposed to implement 1) frequent start-up and minimum load cost bidding and 2) a mechanism for use-limited resources to capture opportunity costs.
Bidding rules enhancementsThrough this initiative the ISO will evaluate the following: 1) unrestricted flexibility of resources to change energy bid prices between the day-ahead and real-time markets, and across real-time hours; 2) restrictions on commitment cost changes between and within the day-ahead and real-time markets; and 3) verification of generator resource characteristics. These proposals may require significant market design and system changes.
Blackstart and system restorationThe ISO proposes tariff amendments to incorporate a new pro-forma blackstart agreement that complies with a revised blackstart resource definition and mandatory reliability standards recently approved by FERC, which become effective July 1, 2013. All generators included in the power restoration plan will be subject to the new standardized agreement. The ISO will also remove related tariff references that will no longer be applicable.
Black start and system restoration phase 2The ISO recently identified a need for immediately procuring additional black start resources beyond those already procured by transmission operators. This initiative will examine cost allocation for incremental black start resources, and address issues associated with additional black start resource procurement.
