Initial Comment for PRR - 1498

Description: SCE opposes BPM PRR 1498. SCE believes that the language and criteria for ""opting in" and "opting out" of Assistance Energy should be completely removed from the BPM. Any action taken that will impact rates should be included in the tariff and not the BPM. SCE recommends the ISO include the following language in the BPM: Prior to deciding if the CAISO will utilize Assistance Energy, the CAISO will hold a stakeholder process to decide. If the CAISO decides to utilize Assistance Energy, the opt-in and opt-out rules which, once adopted, will be included in the tariff. SCE also recommends that CAISO run the Assistance Energy program (without opting-in) for at least a year, gather data, analyze it, and then re-engage CAISO BAA stakeholders.

Initial Comment for PRR - 1498

Description: PG&E appreciates the opportunity to provide comments on Proposed Revision Request (PRR) 1498 related to Assistance Transfer Energy that will be part of the Resource Sufficiency Evaluation (RSE) within the Western Energy Imbalance Market. PG&E requests that CAISO provide additional clarity in the Business Practice Manual about how the CAISO foresees the CAISO Balancing Area Authority (BAA) opt-in / opt-out criteria working in a real-world setting. Before moving forward, the CAISO should provide a few examples within the BPM describing how specific resources and products that did not count towards the RSE failure would result in the reduction of WEIM transfers due to back up generators, strategic reserves, Demand Response, Reliability Demand Response Resources, etc. Including specific examples will help entities, such as PG&E, determine if in fact the proposed language for assistance energy will ensure it used as a last resort and only a last resort, both physically and financially. It is vitally important that load-serving entities with the CAISO BAA understand the implications of what the CAISO is proposing, whereas currently it is not clear based on the current proposed language.

Initial Comment for PRR - 1498

Description: SDG&E appreciates the opportunity to comment on PRR 1498 and believes that the Western Energy Imbalance Market (WEIM) Resource Sufficiency Evaluation (RSE) is moving in the right direction by creating an avenue to address RSE failures with financial penalties rather than physical penalties. However, SDG&E is concerned that CAISO may be jumping into the Assistance Energy Transfer (AET) program without first consulting stakeholders. SDG&E has two primary concerns: 1) Cost and 2) the interaction between AET and LPT exports. With respect to the cost, stakeholders could better assess the cost if CAISO would let the AET program run for a year and use the data to produce an estimate of the cost impact. With respect to the interaction between AET and LPT exports, as SDG&E understands it, if an LPT export clears either the Day-Ahead Market (DAM) or the Hour-Ahead Scheduling Process (HASP), then that export will be locked in when WEIM evaluates the RSE for each Balancing Authority Area (BAA). If CAISO runs into an unexpected contingency between Day-Ahead (DA) and Real-Time (RT), then CAISO could fail the WEIM RSE and trigger the $1,000/MWh penalty price, but the LPT exports might not be cut until the Fifteen Minute Market (FMM) begins to run, or possibly until the next HASP run. As such, CAISO could be paying $1,000/MWh to support LPT exports where those exports are supposed to reflect an economically efficient sale of power. SDG&E therefore proposes that CAISO should run the program for a year in order to gather data on what the estimated cost will be. At that point it should run a stakeholder initiative to engage its Load Serving Entities (LSEs) on the question of whether or not CAISO should opt into the AET program. This would also give CAISO time to address the problem of how AET interacts with LPT exports.
