Review of RSS Event Expectations Entity that experiences the Resource trip submits the RSS event SPP enters event into CRD tool MPs should follow Setpoints to respond Small events are handled solely through changes in Setpoints Large events could require unit commitments  SPP will work directly with the MP to determine which units to commit in order to respond to the event 4

Market Participants MPs with Resources online qualified for Reg, Spin or Supp should submit them as either “Market” or “Fixed” Dispatch Status as they desire for the IDT.  Offline Supp may also be offered as “Market” or “Fixed.” Ramp Rate, Offer Curve and Limits on these Resources should be similar to what is expected to be offered in the IM after go-live. SPP Operators will execute the IDRUC process to identify Resources on Reg for each hour. SPP will dispatch Reg normally by sending a Setpoint to each Resource.  Spin and Supp will be deployed as necessary if an RSS event occurs during the IDT. The SPP BA and RUC Operators may intervene in the Reg and CR Selection process if the deployment of Reg or CR Resources negatively impacts a constraint or if regulation MW’s become unavailable due to a constraint. 5

Dynamic Adjustments and Load Calculations SPP needs to ensure that any adjustments made by the current BAs are included in SPP IM systems through schedules or pseudo ties Dynamic metering must be associated with a dynamic schedule in RTOSS Failure to submit adjustments correctly will result in true up costs and adjustments to load calculation numbers during check out 6
