Phase II Studies Scope & Purpose of Phase II Studies The CAISO, in coordination with the applicable Participating TO(s), will conduct a Phase II Interconnection Study that will incorporate eligible Interconnection Requests from the previous Phase I Interconnection Study. The Phase II Interconnection Study shall: update, as necessary, analyses performed in the Phase I Interconnection Studies to account for the withdrawal of Interconnection Requests from the current Queue Cluster; identify final RNUs needed to physically and reliably interconnect the Generating Facilities and provide final cost estimates; identify final LDNUs needed to interconnect those Generating Facilities selecting Full Capacity or Partial Capacity Deliverability Status and provide final cost estimates, identify final ADNUs for Interconnection Customers selecting Option (B), as provided below and provide revised cost estimates; identify, for each Interconnection Request, the Participating TO’s Interconnection Facilities for the final Point of Interconnection and provide a +/-20% cost estimate; and coordinate in-service timing requirements based on operational studies in order to facilitate achievement of the Commercial Operation Dates of the Generating Facilities. The Phase II Interconnection Study report shall set forth the applicable cost estimates for RNUs, LDNUs, ADNUs and Participating TOs Interconnection Facilities that shall be the basis for the second and third Interconnection Financial Security Postings under GIDAP Section 11.3 and GIDAP BPM Section 8.4. In circumstances where the cost estimations applicable to the total of RNUs and LDNUs are based upon the Phase I Interconnection Study (because the cost estimation for the subtotal of RNUs and LDNUs were lower and so establish maximum cost responsibility under GIDAP Section 10.1 and GIDAP BPM Section 6.2.4.4), the Phase II Interconnection Study report shall recite this fact. Roles and Responsibilities of Participating TO and CAISO
