Initial Comments
SRP appreciates the opportunity to comment on PRR 1501.  SRP is requesting the CAISO clarify ‘participating hybrid resources’ if hybrid dynamic limits are not required for non-participating hybrid resources with a base schedule. Additionally, SRP understands a change to the BPM includes that hybrid dynamic limits may not be used to avoid curtailment of the VER component of a hybrid resource. SRP request the CAISO provide information with respect to how the CAISO will evaluate the use of hybrid dynamic limits of hybrid resource and that the CAISO provide claritiy as to whether it will be verifying if the lower hybrid dynamic limit is at or below zero. SRP recommends the CAISO to make clear the consequences when it is determined an entitiy has leveraged hybrid dynamic limits to avoid curtailment of a hybrid resource VER component. Further, SRP encourages the CAISO to make clear the intended functionality of the lower limit and whether an entity raise the lower hybrid dynamic limit above zero to force a minimum amount of energy.

Thank you for your comment. We will make clarifications around participating hybrid resources and added some language about how misuse of hybrid dynamic limits will be dealt with. CAISO generally doesn't commit to monitoring and consequences, but our Department of Market Monitoring will investigate any perceived misuse of the market.

The intended functionality of the hybrid dynamic limits is to reflect the actual operating range of the hybrid resource within a specific time interval based on the VER component forecast and the storage component SOC. We believe the current BPM language is clear on this point as it states the hybrid dynamic limits cannot be used to avoid curtailment on the VER component.
