Reason For Revision

This BPM outlines how Scheduling Coordinators (SCs) submit Bids, including Self-Schedules and Inter-SC Trades to CAISO, the process CAISO uses to validate Bids, including Self-Schedules and Inter-SC Trades, and how SCs access data on accepted Bids, Self-Schedules Inter-SC Trades, and prices.  This BPM also includes reports for use by EDAM BA entities. ​

Notes:
Initial Comments
• Section 4.2: Bidding Limitations for NGRs
PG&E’s comment: same as what we said under PRR 1665, the use of projected initial SOC for battery resources in the DA will induce reliance on real-time telemetry accuracy, however the BPM does not specify the source or the tolerance of this telemetry (either SC-submitted or by SCADA). We request the following clarifications: 
o The SOC data source (CAISO telemetry vs. SC SIBR submission), 
o The process for correcting erroneous SOC initial conditions, and 
o Whether the SC can trigger a correction request analogous to the existing initial condition correction process.
