Initial Comments
It is WPTF’s understanding that the SUPP value for EIRs is the difference between the DOT and Forecasted output. Thus, the SUPP is negative when the DOT of the resource is less than the forecasted output. WPTF is seeking clarification from the CAISO on how market participants can use the DOT, Neg Supp, and submitted market offers (including both economic offers and self-schedules) to determine when an EIR is curtailed by the market optimization based on the submitted bids versus other operator or out-of-market actions. The proposed language provides additional clarification as to when the DOT may result in a neg SUPP value based on market offers submitted by the EIR, but any additional detail that the CAISO can provide would be greatly appreciated. Ideally, the BPM language would clearly describe how one can determine, based on the DOT and Neg Supp values, when an EIR is dispatched based on the market optimization and submitted offers.

PG&E does not agree with the proposed changes. The negative SUPP is used whenever the Dispatch Instruction is less than the forecast. The Dispatch Instruction may be less than the forecast for reasons other than submitted energy offers from the resource.
