Impact Analysis for PRR - 1665

Description: Because the EDAM BPM is new and has no prior version for comparison, PRRs submitted for this BPM do not require an Impact Analysis (IA) form. An IA will be required for future revisions once the initial EDAM BPM is established.

Initial Comment for PRR - 1665

Description: • Section 3.1.2 Transfer System Resource Types PG&E’s comment: request for clarity on Type 1 and Type 2 TSR registration requirements and on interactions of CAISO BAA SCs with EESCs more broadly. There is ambiguity on the entity responsible for EESC matching and TSR matching. • Section 18.2.3: Intertie Schedules at EDAM Balancing Area Interties (Non-CAISO) PG&E’s comment: for intertie scheduling at the EDAM BA interties, it is stated that SC may “pre-register system resource in anticipation of submission of intertie schedules recognizing the Masterfile processing timelines” but does not provide a specific lead time or expectation of time requirements. Given that CAISO Masterfile changes typically have a range before finalization, there is a risk of SCs being unable to register in time for the May 1 go-live. Please provide a firm deadline for pre-registration of system resources. • Section 18.2.4.2: Intertie Schedules at CAISO Balancing Area Interties with an EDAM Balancing Area PG&E’s comment: The BPM does not specify how an ‘RPS contract’ is verified or whether the SC needs to self-attest. We request more detail that includes: o An explicit verification process, o Clarity on the treatment of RA contracts with sources outside both EDAM and non-EDAM BAAs (e.g., generation in a non-EDAM BAA wheeling through PACE), and o Also this section notes that this is transitional. PG&E would like to see a clear sunset timeline for the transitional period. • Section 20.5.2: Initial Conditions PG&E’s comment: 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.
