Reason For Revision
​Submitted by Susan R. Schneider​, Phoenix Consulting​

Document the CAISO's current practice for determining deliverability status and Net Qualifying Capacity for Mixed-Fuel Resources where both fuel types have been awarded FCDS TPD Allocations, but POI constraints, Local Regulatory Authority (e.g., CPUC) counting rules, and CAISO system limitations prevent them from both being listed as such on the NQC List.
 
Effective date: Effective at end of PRR process.
The CAISO has implemented a complex procedure for managing the shown deliverability status and NQC calculations for Mixed-Fuel Resources where both resources have been found to be fully deliverable but POI constraints, LRA counting rules, and CAISO system limitations prevent them from both being listed as such on the NQC List.  This PRR is needed to document the CAISO's procedure so it is transparent to Interconnection Customers, e.g., for their consideration in making PPA and other commitments for the MFR resources.
