Comments on Second Revised Draft Tariff Language (Phase 2b)

1. Please provide a summary of your organization’s comments on the draft tariff language:

Our comments are mostly clean-up/clarification comments, but we have a few substantive issues, summarized below.  Please see the attached mark-up for additional details.

• ACC constraint relaxation (tariff Section 27.13):  The conditions for this – i.e., relaxation just before the power-balance constraint, and after the CAISO runs out of bids – should be in the tariff, not just the BPMs.

• EIM Entity ACC violations (tariff Section 27.13):  Not clear why the conditions for revoking ACC use are different than for CAISO-area resources, i.e., the CAISO should revoke ACC use directly.

• Hybrid Resource outage reporting (tariff Section 30.5.6.1):  The statement below is unclear - if an outage or de-rate reduces the Hybrid Dynamic Limit, does this mean the outage or de-rate should not be submitted through OMS?  Or, if it’s reported in OMS, the Hybrid Dynamic Limit should not include it?  Perhaps you are trying to address the double-counting issues for UCAP purposes, but this provision needs to be more clearly written.

Scheduling Coordinators should not request outages duplicative of the Hybrid Dynamic Limits.   

• Flexible Capacity (tariff Section 4.10.4.1(g)):  Major issue.  The draft language says HR EFC generally is the sum of the component EFCs, but the overall limit cannot exceed the NQC.  Since storage usually counts for twice the NQC (the positive and negative range), this would effectively cut the storage NQC in half just because it’s in the same Resource ID as another technology.  Flawed technically and policy-wise; discussed in the stakeholder process, but apparently not corrected.

• Shared met data (Appendix Q, new Section 3.1.1.4):  Why the added provision prohibiting wind from sharing met data with another facility, while it’s allowed for solar?  And, when was that discussed in the stakeholder process?
