Transmission Adder. PG&E examined the reasonableness of the PPA using the LCBF evaluation criteria from the 2011 RPS Solicitation. The general finding is that the PPA ranked favorably compared to the other projects received in PG&E’s 2011 RPS Solicitation. A more detailed discussion of PG&E’s evaluation of the PPA is provided in Confidential Appendix A.
Transmission Adder. The transmission adder adjusts Offer prices to include the cost, if any, of bringing the power from the generating facility to PG&E’s network. Once Offers have been ranked on all evaluation criteria except transmission, the means by which the generation will be delivered to PG&E’s customers is examined. Each bid is associated with a transmission cluster based upon the location of the facility. If a CAISO interconnection study has been completed for the project, the costs in that report are used for bid evaluation. If no study has been completed, the project’s transmission costs are based upon either the ability to affect deliveries to PG&E’s load through exchanges, or other commercially-recognized means, or transmission costs are assigned using the transmission ranking cost report methodology. PG&E uses the lesser of the transmission adder or alternative commercial arrangements in determining the market value of bids and selecting the shortlist. PG&E’s determination of any transmission adder is confidential and can be found in Confidential Appendix A.
Transmission Adder. PG&E examined the reasonableness of the PSA using the LCBF evaluation criteria from the 2012 RPS Solicitation. The general finding is that the PSA ranked favorably compared to the other projects received in PG&E’s 2012 RPS Solicitation. A more detailed discussion of PG&E’s evaluation of the PSA is provided in Confidential Appendix A.
Transmission Adder. PG&E examined the reasonableness of the three PPAs using the LCBF evaluation criteria from the 2011 RPS Solicitation. The general finding is that the three PPAs ranked favorably compared to the other projects received in PG&E’s 2011 RPS Solicitation. A more detailed discussion of PG&E’s evaluation of the three PPAs is provided in Confidential Appendices A1 – A3.

Once Offers have been ranked on all evaluation criteria except transmission, the means by which the generation will be delivered to PG&E’s customers is examined. Each bid is associated with a transmission cluster based upon the location of the facility. If a CAISO interconnection study has been completed for the project, the costs in that report are used for bid evaluation. If no study has been completed, the project’s transmission costs are based upon either the ability to affect deliveries to PG&E’s load through exchanges, or other commercially-recognized means, or transmission costs are assigned using the transmission ranking cost report methodology. PG&E uses the lesser of the transmission adder or alternative commercial arrangements in determining the market value of the bids and selecting the short list. Available capacity at each transmission cluster (if any) is assigned to the bids at each cluster based on rank. Each bid is then assigned the transmission cost adder indicated by the Transmission Ranking Cost Report (TRCR) as necessary to accept its project capacity on the transmission network. The cluster-based cost adders are used for bid evaluation only. Resource projects do not have to physically connect to a cluster, and connecting projects do not necessarily pay the interconnection prices listed in the TRCR. After the initial ranking of Offers on Market Valuation, the team calculating the transmission adder receives a download of data for each Offer. The data is grouped by transmission cluster and sorted by Market Valuation, from highest to lowest. PG&E assigns each Offer an estimated amount of transmission network upgrade costs, if applicable, using the Transmission Ranking Cost Table in the 2009 RPS Solicitation Protocol. Within each of the transmission clusters, PG&E has identified various levels of possible additional transmission capacity, in megawatts, and the related costs, in dollars, of providing that capacity. These megawatts and dollars in the table are divided between “Peak and Shoulder” and “Night” periods. Within each of the transmission clusters, and within each period (Peak and Shoulder and Night), starting with the highest scoring Offer, each Offer is assigned a pro-rata share of the cost. This share is based on the Offer’s maximum MW as a percentage of the maximum MW of potential genera...
Transmission Adder. PG&E requests transmission information from developers from each Offer. This information includes the proposed project’s current interconnection queue position, application status, and transmission provider. Details of the current or proposed interconnection are requested for the projects, including voltage level, transmission or distribution service level, transmission line, interconnecting substation, form of interconnection applied for, and a copy of the study, or interconnection agreement, if applicable. The transmission adder adjusts Offer prices to include the cost, if any, to customers of bringing the power from the generating facility to PG&E’s network. Once Offers have been ranked on all evaluation criteria except transmission, the means by which the generation will be delivered to PG&E’s customers is examined. Each bid is associated with a transmission cluster based upon the location of the facility. If a CAISO interconnection study has been completed for the project, the costs in that report are used for bid evaluation. If no study has been completed, the project’s transmission costs are assigned using the transmission ranking cost report methodology. The Transmission Ranking Cost Report (“TRCR”) proxy costs include reliability network upgrades, plus deliverability upgrades. Some sellers in the 2011 RPS Solicitation had received studies that were based on their application as an energy-only resource, but did not have a deliverability assessment to qualify for resource adequacy. Each Offer that does not have a CAISO interconnection study is assigned the transmission cost adder indicated by the TRCR as necessary to accept its project capacity on the transmission network. The cluster-based cost adders are used for bid evaluation only. Projects do not have to physically connect to a cluster, and connecting projects do not necessarily pay the interconnection prices listed in the TRCR. PG&E assigns each Offer an estimated amount of transmission network upgrade costs using project specific interconnection studies, if available, or using a proxy cost estimate based on the TRCR. For projects located in PG&E, Southern California Edison (“SCE”) or San Diego & Electric (“SDG&E”) service territories, PG&E applies the PG&E, SCE, or SDG&E TRCR. The MW and dollars in the TRCR table are divided between “Peak & Shoulder” and “Night” periods (note that the dollars for “Baseload and As-Available columns are simply the sum of the other two sets of columns minus any ...
