6 ADVICE 3120-E (U 338-E) October 28, 2014 The RE Tranquillity Contract is based on SCE s 2013 Pro Forma Renewable Power Purchase and Sale Agreement, which was accepted by the Commission in Decision ( D. ) on November 14, SCE is purchasing all electric energy produced by the RE Tranquillity Project through the contract term, net of station use (if any), and all green attributes, capacity attributes, and resource adequacy benefits generated by, associated with, or attributable to the RE Tranquillity Project. The delivery point is at the point of interconnection with the California Independent System Operator ( CAISO ) Controlled Grid within PG&E s service territory. Additional information regarding the deal structure of the RE Tranquillity Contract is provided in Appendix D. The RE Tranquillity Project also met all of the eligibility requirements and preferred project characteristics for SCE s 2013 Request for Proposals ( RFP ), which is described in further detail in Section 3. The RE Tranquillity Project is expected to deliver a portfolio content category 1 ( Category 1 ) 5 product, and has a first point of interconnection within a California Balancing Authority. F. RPS Statutory Goals & Requirements By providing renewable energy from an eligible renewable energy resource ( ERR ) as defined under the RPS Legislation, the RE Tranquillity Project is consistent with, and contributes to, the RPS program s statutory goals. Pursuant to Public Utilities Code Section (b), the Legislature determined that procurement of electricity products from ERRs, such as the RE Tranquillity Project, provides unique benefits to California, including among other things, displacing fossil fuel consumption within the state, reducing air pollution in the state, meeting the state s climate change goals by reducing emissions of greenhouse gases associated with electrical generation, and meeting the state s need for a diversified and balanced energy generation portfolio. Based on SCE s analysis of its renewable net short ( RNS ) position, SCE projects a long-term renewable procurement need in the third compliance period and beyond. Consistent with this need, the RE Tranquillity Contract will provide long-term RPS and portfolio category 1-eligible energy over a twenty-year term starting in SCE s RNS calculations are included in Appendix G.

II. CONSISTENCY WITH COMMISSION DECISIONS A. SCE s 2013 RPS Procurement Plan 1. SCE s 2013 RPS Procurement Plan Was Approved by the Commission and SCE Adhered to Commission Guidelines for Filing and Revisions 6 D at 80 (Ordering Paragraphs 1 and 2). 7 Id., Appendix 1.

8 ADVICE 3120-E (U 338-E) October 28, 2014 SCE filed its 2013 RPS Procurement Plan on June 28, On August 28, 2013, SCE filed a motion to amend its 2013 RPS Procurement Plan, which included an amended 2013 RPS Procurement Plan as an attachment. In D , the Commission conditionally approved SCE s 2013 RPS Procurement Plan, including the solicitation materials for SCE s 2013 RPS solicitation. 8 The Commission also ordered SCE to make certain changes to its 2013 RPS Procurement Plan and to file a final plan by December 4, On December 4, 2013, SCE filed and served its final 2013 RPS Procurement Plan. On December 13, 2014, SCE re-filed and served its final 2013 RPS Procurement Plan to make some minor corrections. Consistent with the schedule set forth in D , SCE issued its 2013 RFP on January 6, Summary of SCE s Assessment of Portfolio Needs and Preferred Project Characteristics As explained in SCE s 2013 RPS Procurement Plan and shown in SCE s RNS calculations, SCE has a long-term need for renewable energy in the third compliance period and beyond. In the 2013 RPS Procurement Plan, SCE received approval to conduct a targeted solicitation to meet SCE s need for renewable resources. In its 2013 RPS RFP, SCE accepted proposals for projects with commercial operation dates of January 1, 2016 or later, and limited its procurement to Category 1 products. SCE also required that projects have either a Phase II Interconnection Study or an equivalent or better process or exemption in order to submit a proposal. Projects with a contract capacity of 1.5 MW or greater were eligible to participate in SCE s 2013 RPS RFP. However, SCE indicated a strong preference for projects with contract capacities: (1) greater than 20 MW for projects located within the service territories of SCE, PG&E, and San Diego Gas & Electric Company ( SDG&E ) and directly interconnected to the CAISO or the distribution systems of SCE, PG&E or SDG&E; (2) 3 MW or greater for projects located outside the service territories of SCE, PG&E, and SDG&E and directly interconnected to the transmission or distribution system of a California Balancing Authority; or (3) 1.5 MW or greater for projects located within the Western Los Angeles sub-area of the Los Angeles basin local reliability area, or in the Moorpark sub-area of the Big Creek/Ventura local reliability area. Additionally, for in state generating facilities that are, or will be, interconnected to the CAISO, SCE required that the delivery point be point where the generating facility connects to the CAISO controlled grid. For in-state generating facilities that are, or will be interconnected to a California Balancing Authority other than 8 D at 69 (Ordering Paragraph 1).

9 ADVICE 3120-E (U 338-E) October 28, 2014 the CAISO, SCE required the delivery point be the intertie point where the seller s transmission provider ties to the CAISO. SCE decided on the total projected contract energy it signed based on several factors laid out in the 2013 RPS Procurement Plan, including projected long- and short-term needs, the impact of reducing federal tax credits, and expected contract success rates. 3. The RE Tranquillity Contract Is Consistent With SCE s 2013 RPS Procurement Plan, Portfolio Needs, and Preferred Project Characteristics The RE Tranquillity Contract aligns with the portfolio needs identified in SCE s 2013 RPS Procurement Plan. Specifically, the RE Tranquillity Contract will provide renewable energy from a new 206 MW solar PV facility starting in 2019 for a 15-year term, consistent with SCE s long-term renewable procurement need in the third compliance period and beyond. The RE Tranquillity Project also met all of the eligibility requirements and preferred project characteristics for SCE s 2013 RFP. The RE Tranquillity Project s first point of interconnection will be with the CAISO, and thus the RE Tranquillity Contract will provide Category 1 product. Additionally, the RE Tranquillity Project s 206 MW contract capacity is consistent with SCE s preference for projects with contract capacities of 20 MW or greater (for projects located within the service territories of SCE, PG&E, and SDG&E and directly interconnected to the CAISO or the distribution systems of SCE, PG&E, or SDG&E). The RE Tranquillity Project will also satisfy the delivery requirements for SCE s 2013 RFP because the project s delivery point will be the point where the project connects to the CAISO controlled grid. 4. The RE Tranquillity Contract Is Consistent With SCE s Portfolio Optimization Strategy As described in detail in SCE s 2013 RPS Procurement Plan, 9 the objective of SCE s renewables portfolio optimization strategy is to minimize costs to its customers while ensuring that RPS procurement goals are met or exceeded. SCE determines the procurement target for each RPS solicitation based in part on its assessment of SCE s renewable procurement position and need, i.e., SCE s RNS. This includes a calculation of SCE s net short or long renewables position and SCE s bank. SCE carefully evaluates its renewable procurement need by assessing bundled retail sales, the performance and variability of 9 See Southern California Edison Company s (U 338-E) Final 2013 Renewables Portfolio Standard Procurement Plan, December 4, 2013 ( Final 2013 RPS Plan ), at

10 ADVICE 3120-E (U 338-E) October 28, 2014 existing generation, the likelihood of new generation achieving commercial operation, expected commercial on-line dates, technology mix, expected curtailment, and the impact of pre-approved procurement programs, among other factors. The RE Tranquillity Contract meets the primary objectives of SCE s portfolio optimization strategy. The RE Tranquillity Contract is expected to start delivery in December 2019, which will help meet SCE s renewable procurement need in the third compliance period and beyond. Additional information is included in Appendix A, Section A.7. B. Least-Cost/Best-Fit ( LCBF ) Methodology and Evaluation SCE evaluates and ranks proposals based on LCBF principles that comply with criteria set forth by the Commission in D and D (the LCBF Decisions ). 10 The goal of SCE s evaluation and selection criteria and processes is to provide decision metrics so that SCE can procure renewable energy economically, while providing the most value to its customers. The LCBF analysis evaluates both quantitative and qualitative aspects of each proposal to estimate its value to SCE s customers and its relative value in comparison to other proposals. While assumptions and methodologies have evolved slightly over time, the basic components of SCE s evaluation and selection criteria and process for RPS contracts were established by the Commission s LCBF Decisions. Consistent with those LCBF Decisions, the three main steps undertaken by SCE in its evaluation and selection process were: (i) initial data gathering and validation; (ii) a quantitative assessment of proposals; and (iii) adjustments to selections based on proposals qualitative attributes. SCE applied these criteria to the proposals received in its 2013 RPS RFP in order to establish a short list of proposals from sellers with whom SCE would engage in a final round of contract discussions. Prior to receiving proposals, SCE finalized the short list selection criteria with the Independent Evaluator ( IE ). SCE then finalized the major assumptions and methodologies that underlie SCE s valuation, including power and gas price forecasts, SCE s existing and forecast resource portfolio, and SCE s firm capacity value forecast. SCE also finalized and published congestion adders for sellers to use in preparing their proposals. Once proposals were received, SCE began an initial review of bids for completeness and conformity with the solicitation protocol. The review included 10 The Commission has also made rulings on various evaluation criteria in its decisions on the IOUs RPS procurement plans.

11 ADVICE 3120-E (U 338-E) October 28, 2014 an initial screen for required submission criteria such as a conforming delivery point, commercial on-line date in 2016 or later, a valid interconnection study, minimum project size, and the submission of particular proposal package elements. Sellers lacking any of these items were allowed a reasonable cure period to remedy any deficiencies. Following this check for conformity, SCE conducted an additional review to determine the reasonableness of proposal parameters such as generation profiles and capacity factors. SCE worked directly with sellers to resolve any issues and ensure the data was ready for evaluation. After these reviews, SCE performed a quantitative assessment of each proposal individually and subsequently ranked them based on the proposal s benefit and cost relationship. Specifically, the total benefits and total costs were used to calculate the net levelized cost or Renewable Premium per each complete and conforming proposal. Benefits were comprised of separate capacity, energy and congestion components, while costs included the contract payments, debt equivalence, congestion cost, and transmission cost. SCE discounted the monthly benefit and cost streams to a common base date. The result of the quantitative analysis was a merit-order ranking of all complete and conforming proposals Renewable Premiums that helped define the preliminary short list. In parallel with the quantitative analysis, SCE conducted an in-depth assessment of the qualitative attributes of the top proposals with a competitive renewable premium. This analysis utilized the Project Viability Calculator 11 to assess certain factors, including the company/development team, technology, and development milestones. Additional attributes such as transmission area, facility interconnection process progress, portfolio fit of commercial operation date, resource diversity, and counterparty concentration were also considered in the qualitative analysis. These qualitative attributes were then considered to either eliminate non-viable proposals or add projects with high viability or other beneficial qualitative attributes to the final short list of proposals, or to break ties, if any. Following both its quantitative and qualitative analysis, SCE consulted with its Procurement Review Group ( PRG ) regarding the final short list and specific evaluation criteria. SCE then negotiated with the shortlisted sellers for a 90 day period. At the end of the contract negotiation period, all sellers that completed negotiations had a one-time opportunity to submit new pricing. SCE then made final selections based on the new pricing and consulted with its IE and the PRG prior to the execution of any successfully negotiated contracts. 11 The results of the Project Viability Calculator are included in Appendix A.

12 ADVICE 3120-E (U 338-E) October 28, 2014 SCE s 2013 RPS Short List Report was submitted to the Commission on April 21, 2014 in Advice 3029-E. SCE filed a supplement to Advice 3029-E to identify two projects that withdrew from the short list on June 26, The Energy Division approved SCE s 2013 RPS Short List Report effective as of July 8, Using SCE s LCBF methodology, the RE Tranquillity Project compared favorably to other proposals received in the 2013 RPS RFP as well as other procurement options available to SCE. C. Compliance With Standard Terms and Conditions In D , the Commission established a number of modifiable and nonmodifiable standard terms and conditions to be used by retail sellers when contracting for RPS-eligible resources. 12 In D , the Commission reduced the number of non-modifiable terms to the following four terms: (1) CPUC Approval; (2) RECs and Green Attributes; 13 (3) Eligibility; and (4) Applicable Law. 14 The remaining non-modifiable terms were converted to modifiable terms. 15 In D , as modified by D , the Commission added two new non-modifiable standard terms and conditions for both bundled contracts and contracts for renewable energy credits ( RECs ) only: (1) Transfer of Renewable Energy Credits; and (2) Tracking of RECs in WREGIS. 16 The Commission also added a new version of the non-modifiable CPUC Approval standard term and condition for REC-only contracts, and held that the non-modifiable Applicable Law standard term and condition also applies to REC-only contracts. In D , the Commission updated the non-modifiable RECs and Green Attributes term to a modifiable Bioenergy Transactions term. 17 The RE Tranquillity Contract includes all non-modifiable standard terms and conditions for bundled contracts without change as indicated in the table below. NON-MODIFIABLE CONTRACT SECTION CONTRACT PAGE 12 D at 20 (Ordering Paragraph 1) and Appendix A. 13 In D , Appendix B, the Commission revised the non-modifiable RECs and Green Attributes standard term and condition. 14 D at 33 (Ordering Paragraph 1.a). 15 Id. at 34 (Ordering Paragraph 1.b). Subsequently, in D , the Commission compiled the standard terms and conditions in one document and deleted the modifiable standard term and condition on supplemental energy payments. 16 D at 46 (Ordering Paragraph 3.P). 17 D at 24-25, 70 (Ordering Paragraph 6).

D. Portfolio Content Category Claim and Upfront Showing In D , the Commission found that [a] retail seller claiming that procurement for compliance with the California renewables portfolio standard from a procurement contract or ownership agreement signed... on or after June 1, 2010 counts in the portfolio content category described in Pub. Util. Code (b)(1), must provide information to the Director of Energy Division sufficient to demonstrate that the generation facility from which the electricity is procured is certified as eligible for the California renewables portfolio standard. 18 Additionally, retail sellers claiming procurement counts as Category 1 product must provide information to the Energy Division Director sufficient to demonstrate that the generating facility from which the electricity is procured meets the statutory definition of Category 1 products set forth in Public Utilities Code Section (b)(1). 19 One way to make this demonstration is to show that the facility has its first point of interconnection to the Western Electricity Coordinating Council transmission grid within the metered boundaries of a California balancing authority area. 20 The retail seller must also demonstrate that the renewable energy credits originally associated with the electricity have not been unbundled and transferred to another owner, and that all other 18 D at (Ordering Paragraph 1). 19 See id. 20 Id.

14 ADVICE 3120-E (U 338-E) October 28, 2014 requirements for procurement for compliance with the California renewables portfolio standard are met by the procurement. 21 Furthermore, D provides that the utilities, in seeking approval of contracts for procurement, should enable the Commission to evaluate the following: the claimed portfolio content category of the proposed procurement; the risks that the procurement will not ultimately be classified in the claimed portfolio content category; the value to ratepayers of the procurement as proposed and the value to ratepayers if the procurement is not ultimately classified in the claimed portfolio content category. 22 Pursuant to the provisions in the RE Tranquillity Contract, SCE will procure energy, capacity and associated renewable energy attributes generated from a California-based eligible renewable resource with a first point of interconnection within the CAISO. In addition, per the contract, the RE Tranquillity Project must obtain and keep current California Energy Commission ( CEC ) certification as an ERR, 23 as well as perform all actions necessary to effectuate the transfer of RECs to SCE in the Western Renewable Energy Generation Information System ( WREGIS ). The RECs associated with the electricity from the RE Tranquillity Project are yet to be delivered and therefore have not been unbundled or transferred to another owner. Such RECs will be transferred to SCE pursuant to the terms of the RE Tranquillity Contract. Accordingly, this is a Category 1 transaction pursuant to the Public Utilities Code Section (b)(1) and D Additionally, a risk that the RE Tranquillity Project will fail to delivery Category 1 RECs has not been identified. 21 Id. at 76 (Ordering Paragraph 1). 22 Id. at 80 (Ordering Paragraph 9). 23 The project must qualify and be certified by the CEC as an ERR as such term is defined in Public Utilities Code Section (e). 24 D at (Ordering Paragraph 14).

16 ADVICE 3120-E (U 338-E) October 28, 2014 E. Long-Term Contracting Requirement In D , the Commission held that, [i]n order to count procurement from contracts of less than 10 years duration signed after June 1, 2010 for compliance with the California renewables portfolio standard in a compliance period, a retail seller must sign in the compliance period in which the short-term contract is signed, contracts of at least 10 years in duration with expected generation equal to at least 0.25 percent of the retail sales for the immediately prior compliance period. 27 Since a compliance period does not exist prior to the compliance period, the requirement is 0.25 percent of 2010 retail sales for that compliance period. 28 The RE Tranquillity Contract is a 15-year contract. Therefore, the long-term contracting requirement does not apply. F. Interim Emissions Performance Standard The California Legislature passed Senate Bill ( SB ) 1368 on August 31, 2006, and Governor Schwarzenegger signed the bill into law on September 29, Section 2 of SB 1368 adds Public Utilities Code Section 8341(a), which provides, No load-serving entity or local publicly owned electric utility may enter into a long-term financial commitment unless any baseload generation supplied under the long-term financial commitment complies with the greenhouse gases emission performance standard established by the commission, pursuant to subdivision (d). for load serving entity. 29 In order to institute the provisions of SB 1368, the Commission instituted Rulemaking That proceeding resulted in the establishment of a greenhouse gas ( GHG ) emissions performance standard ( EPS ) for carbon dioxide ( CO 2 ). In D , the Commission noted, SB 1368 establishes a minimum performance requirement for any long-term financial commitment for baseload generation that will be supplying power to California ratepayers. The new law establishes that the GHG emissions rates for these facilities must be no higher than the GHG emissions rate of a combined-cycle gas turbine ( CCGT ) powerplant. 30 The decision further explains: SB 1368 describes what types of generation and financial commitments will be subject to the EPS ( covered procurements ). Under SB 1368, the EPS applies to baseload generation, but the requirement 27 D at 98 (Ordering Paragraph 15). 28 See id. at 98 (Ordering Paragraph 16). 29 Cal. Pub. Util. Code 8341(a). 30 D at 2-3.

17 ADVICE 3120-E (U 338-E) October 28, 2014 to comply with it is triggered only if there is a longterm financial commitment by an LSE. The statute defines baseload generation as electricity generation from a powerplant that is designed and intended to provide electricity at an annualized plant capacity factor of at least 60%.... For baseload generation procured under contract, there is a long-term commitment when the LSE enters into a new or renewed contract with a term of five or more years. 31 The RE Tranquillity Contract is exempt from EPS regulations because it has an expected annualized capacity factor well below the threshold baseload capacity factor of 60 %, above which the EPS rules would apply. 32 G. PRG Participation SCE s PRG was formed on or around September 10, Participants include representatives from various divisions within the Commission, the Office of Ratepayer Advocates, The Utility Reform Network, California Utility Employees, the Union of Concerned Scientists, and the California Department of Water Resources. SCE consulted with its PRG during each milestone of the 2013 RPS solicitation process. Among other things, SCE informed the PRG of the initial results of its RFP, explained the evaluation process, and updated the PRG periodically concerning the status of contract formation. On March 19, 2014, SCE advised the PRG of its proposed short list of bids for its 2013 RPS solicitation. On July 16, 2014, SCE briefed the PRG on the proposed execution of the RE Tranquillity Contract. H. Independent Evaluator ( IE ) The IE for the 2013 RPS solicitation was Merrimack Energy Group, Inc. The IE joined and contributed to a number of conference calls and negotiation sessions. In addition, the IE reviewed traffic, the RE Tranquillity Contract, and other documents exchanged by the parties. The IE also participated in the PRG review. The IE Report is included as Appendix C. 31 Id. at See id., Attachment 7 at 1.

CONTINGENCIES AND MILESTONES The RE Tranquillity Project is expected to begin commercial operation on December 1, Specific information regarding performance criteria and guaranteed milestones is provided in Appendices A and D through F. V. SAFETY CONSIDERATIONS SCE is strongly committed to safety in all aspects of its business. Renewable sellers are responsible for the safe construction and operation of their generating facilities and compliance with all applicable safety regulations. SCE has taken several steps to address those issues over which it has the most visibility and control the delivery of renewable electricity products to SCE in a reliable, safe, and operationally sound manner. SCE s 2013 Pro Forma Renewable Power Purchase and Sale Agreement already provided that the seller must operate the generating facility in accordance with Prudent Electrical Practices. 34 Consistent with SCE s focus on safety, SCE added a provision to its 2013 Pro Forma Renewable Power Purchase and Sale Agreement providing that, prior to commencement of any construction activities on the project site, the seller must provide to SCE a report from an independent engineer certifying that the seller has a written plan for the safe construction and operation of the generating facility in accordance with Prudent Electrical Practices. 35 See Appendix D for more details. 34 See Final 2013 RPS Plan, Appendix G.1 at Section 3.12(a), Exhibit A, Section 215. Prudent Electrical Practices means those practices, methods and acts that would be implemented and followed by prudent operators of electric generating facilities in the Western United States, similar to the Generating Facility, during the relevant time period, which practices, methods and acts, in the exercise of prudent and responsible professional judgment in the light of the facts known at the time a decision was made, could reasonably have been expected to accomplish the desired result consistent with good business practices, reliability and safety. Prudent Electrical Practices includes, at a minimum, those professionally responsible practices, methods and acts described in the preceding sentence that comply with the manufacturer s warranties, restrictions in this Agreement, and the requirement of Governmental Authorities, WECC standards, the CAISO and Applicable Laws See id., Appendix G.1, Section 3.11(e).

32 Executive Summary Effective July 31, 2014, Southern California Edison Company ( SCE ) executed a power purchase agreement ( PPA ) with RE Tranquillity LLC ( RE Tranquillity ) for the purchase of all the electric energy, capacity, Resource Adequacy ( RA ) benefits, and Green Attributes produced by a proposed 206 MW (AC) solar photovoltaic ( PV ) generating facility to be constructed near Tranquillity, California pursuant to SCE s 2013 Request for Proposals from Eligible Renewable Energy Resource Suppliers for Renewable Products ( 2013 Renewable RFP ). SCE launched the 2013 Renewable RFP on January 6, 2014, received indicative bids on January 31, 2014, and received final offers on June 25, On July 29, 2014 and July 31, 2014, SCE signed a total of eight power purchase agreements for capacity, energy and other products from eight different projects representing a total of approximately 1,550 MW, including 206 MW of energy, capacity and Green Attributes purchased under the PPA with RE Tranquillity ( Tranquillity PPA ). 1 Through the 2013 Renewable RFP solicitation, SCE sought Proposals for products qualifying as Portfolio Content Category 1 2 which includes all electric energy produced by an Eligible Renewable Energy Resource ( ERR or ERR Generating Facility ) as well as all attributes, including all Green Attributes, all Capacity Attributes, and all Resource Adequacy Benefits generated by, associated with or attributable to the output of the ERR Generating Facility. Pursuant to the 2013 Renewable RFP, SCE received a large number of proposals from renewable energy developers, reviewed and evaluated the proposals relative to the eligibility and conformance requirements listed in the Protocol Document, evaluated and ranked the proposals, and determined which of those offers to include on a short list for potential negotiations and contracting. 3 In March 2014, SCE selected including three geothermal projects selected out of economic rank order, the 1,600 GWh/year target for this solicitation. Subsequent to short list selection on or around March 19, 2014, for the next three months, 1 Capitalized terms when used with reference to the Tranquillity PPA and not otherwise defined herein are as defined in the Tranquillity PPA. 2 The first portfolio content category ( Category 1 ) is delineated in the California Public Utilities Commission s Decision Implementing Portfolio Content Categories for the Renewables Portfolio Standard Program, D (2011). It consists of products from renewable energy generators: with a first point of interconnection to the Western Electric Coordinating Council transmission system within the boundaries of a California Balancing Authority Area ( CBA ); or with a first point of interconnection with an electricity distribution system used to serve end users within the boundaries of a CBA; or where the renewable generation is scheduled into a CBA without substituting electricity from another source; or where the generation from the renewable facility is dynamically transferred to a CBA. 3 SCE implemented a two-step evaluation process for this solicitation. The shortlist selection was the first step in the process. After shortlist selection, SCE initiated contract negotiations with shortlisted projects. At the end of the negotiation period, Sellers who had reached agreement with SCE on the terms of a PPA have a one-time opportunity to submit a final revised price. SCE made final selections and entered into final PPAs based on the revised pricing and a quantitative and qualitative evaluation of the project proposals. Merrimack Energy Group, Inc. 2
