Idaho Power Company comments:
With PRR 1181, CAISO is proposing to significantly increase the requirements for Master File change requests.  Idaho Power objects to the magnitude of these changes and the additional burden these changes place on EIM Entities.  CAISO has not provided justification or explanation for why these changes are necessary except to support Corporate Goal 4a. Please identify what Corporate Goal 4a is and how these changes are necessary for that objective.

Idaho Power does not support the changes and recommends the proposed language not be adopted for all SC’s in the market.  If CAISO adopts the proposed language for resources within the CAISO BAA, it should retain the existing current requirements, without these proposed changes, for resources in EIM Entity BAAs.  The additional information the proposed language would require is unduly burdensome and would materially increase the time required to make Master File changes and potentially increase the rejection rate of changes an EIM Entity needs on resources in its BAA.  Entities can discover that changes are necessary to how a resource is modelled in the normal course of business, and should be able to make those corrections without burdensome information requirements.  Moreover, the proposed required information is unnecessary for resources not in the CAISO BAA, and CAISO should not be in the position of verifying whether EIM Entities are modeling their resources correctly.  Entities are already required by section 4.6.4 of the CAISO Tariff to ensure that resources are modelled correctly.   In addition, incorrect modeling of resources in the EIM Entity’s BAA can lead to financial and reliability issues, a further incentive to ensure these are correctly represented in the model. The proposed changes should not be adopted, or if adopted, should be limited to resources internal to the CAISO BAA.

Thank you for the opportunity to comment.

---------------------------------------------
The concept of age-adjusted design capability is in the tariff today and is not part of this BPM revision.  The ISO fundamentally disagrees that it should not perform a due diligence review prior to implementing changes in the Master File.

---------------------------------------------
The ISO believes that OEM manuals are just one way that an entity could demonstrate an age-adjusted design capability.  The ISO has changed the language in the Recommendation phase to clarify that only an explanation for the change is required upon initial submittal of the change.  Only if the explanation does not adequately support the request would the ISO ask for additional supporting materials that the Scheduling Coordinator and Generator Owner would have used as a basis for their change request.  The ISO believes that this process provides an appropriate due diligence review for changes being implemented in the Master File.
