Initial Comments
The CAISO has received written comments from Amber Clinkscales at SRP:

SRP appreciates the opportunity to comment on PRR 1532. SRP requests clarification be added to the BPM regarding the timing of negative/0MW telemetry and/or startup conditions that would be relevant for the test and exemption eligibility.  The training for market simulations mentioned that the relevant timeframe was 5 minutes before the start of the test.  This information should be detailed in the BPM.  It may also be more accurate to say that resources that can be “in startup” with a 0MW or negative MW telemetry are exempted, rather than resources that can be “online”.  SRP is unsure what definition of online is for this exemption.  SRP also recommends including an example or two to better understand which resources are eligible for this flag.  As written, there is not enough information to determine which resources would meet the timing criteria.

There is no redline or existing language change with this PRR.  It is only the addition of the short sentences shown in the Proposed Language section of this PRR.   We understand your question about the addition of this type of test in the Bid Capacity test, which was implemented July 1, 2023.  This PRR is an exemption to this test based upon the physical characteristics of certain resources for which an exemption makes sense.

NV Energy does not understand the reason for this addition.  Could CAISO please refer to the section in the draft final proposal that explains this new feature? Additionally, there is not an attachment in this PRR showing the redlined language for the addition.  It is our understanding that the capacity test does not include any intertemporal constraints, therefore, we do not understand why this addition is necessary.

Recommendation Comments
SRP appreciates the additional detail provided by the CAISO.  It would be helpful to include examples along with the timeline for telemetry checks for specific resource types and scenarios where this might apply.
