Subject of the Advice Letter The El Cabo Contract contemplates a proposed 298 megawatt ( MW ) wind facility (the El Cabo Wind Project ) to be located in central Torrance County, New Mexico (the Site ). The El Cabo Wind Project will interconnect to the Public Service of New Mexico s ( PNM s ) to-be-built Clines Corner Substation on PNM s existing 345 kv BA-Blackwater line via a new switching station and 30 mile 345 kv gen-tie line from the Site. The seller under the El Cabo Contract is El Cabo Wind LLC, a limited liability company. The parent company of Seller is Iberdrola Renewables, LLC, an Oregon limited liability company ( Iberdrola ). Iberdrola will serve as the developer, operator, and the operations and maintenance ( O&M ) service provider for the El Cabo Wind Project. The El Cabo Contract is a new contract that originated from SCE s 2014 RPS solicitation.

4 ADVICE 3360-E (U 338-E) February 9, 2016 C. General Project Description Project Name El Cabo Wind Project Technology Wind Capacity (MW) 298 Capacity Factor (Term Year 1) 47.70% Expected Generation (GWh/Year) 1 1,245 Initial Commercial Operation Date December 1, 2017 Date Contract Delivery Term Begins December 1, 2017 Delivery Term (Years) 20 Vintage (New / Existing / Repower) Location (City and State) Control Area (e.g., California Independent System Operator ( CAISO ), Bonneville Power Administration ( BPA )) Nearest Competitive Renewable Energy Zone ( CREZ ) as identified by the Renewable Energy Transmission Initiative ( RETI ) Type of cooling, if applicable New Central Torrance County, New Mexico PNM N/A N/A D. Project Location The El Cabo Wind Project will be located in central Torrance County, New Mexico, approximately seven miles east-south-east of Estancia, seven miles north-north-west of Willard, and sixty miles east of Albuquerque. 1 This expected generation represents the annual average of generation that SCE expects to make payments on over the contract term.

5 ADVICE 3360-E (U 338-E) February 9, 2016 Approximately 2% of the Site is anticipated to be used for the El Cabo Wind Project s infrastructure. The remaining land, approximately 98%, will continue to be used for traditional land uses, primarily ranching and grazing, during operation of the El Cabo Wind Project. E. General Deal Structure The El Cabo Contract is based on SCE s 2014 Pro Forma Renewable Power Purchase and Sale Agreement, which was accepted by the Commission in Decision ( D. ) on November 20, As described in Appendix D (Contract Summary), the El Cabo Contract includes modifications to the Pro 2 D at 124 (Ordering Paragraph 1).

6 ADVICE 3360-E (U 338-E) February 9, 2016 Forma to account for out-of-state, project-specific operational requirements such as dynamic scheduling and out-of-state transmission service. SCE is purchasing all electric energy produced by the El Cabo Wind Project throughout 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 El Cabo Wind Project. The delivery point is at the existing CAISO scheduling point at Four Corners, or if Four Corners ceases to be a CAISO scheduling point, the delivery point shall be the Willow Beach scheduling point, which is also a CAISO scheduling point. The El Cabo Wind Project has met all of the eligibility requirements and preferred project characteristics for SCE s 2014 Request for Proposals ( RFP ), which are described in further detail in Sections II.A.2 and II.A.3. The El Cabo Wind Project is expected to deliver a portfolio content category 1 ( Category 1") product. The generation from the El Cabo Wind Project is expected to qualify as Category 1 since Seller is obligated to dynamically schedule such generation into the CAISO, a California Balancing Authority, without substituting electricity from any other source. Additional information regarding the deal structure of the El Cabo Contract is provided in Appendix D. F. RPS Statutory Goals and Requirements By providing renewable energy from an eligible renewable energy resource ( ERR ) as defined in the RPS Legislation, the El Cabo Contract 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 El Cabo Wind 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 prior to executing 2014 RPS solicitation contracts, SCE projected a long-term renewable procurement need in the third compliance period and beyond. Consistent with that need, the El Cabo Contract is expected to provide long-term RPS Category 1 eligible energy over twenty-year terms starting in SCE s RNS calculations are included in Appendix G.

II. CONSISTENCY WITH COMMISSION DECISIONS A. SCE s 2014 RPS Procurement Plan 1. SCE s 2014 RPS Procurement Plan Was Approved by the Commission and SCE Adhered to Commission Guidelines for Filing and Revisions SCE filed its 2014 RPS Procurement Plan on June 4, On August 20, 2014, SCE filed an amended 2014 RPS Procurement Plan. In D , the Commission conditionally accepted SCE s 2014 RPS Procurement Plan, including the solicitation materials for SCE s 2014 RPS 3 D at 80 (Ordering Paragraphs 1 and 2). 4 Id., Appendix 1.

8 ADVICE 3360-E (U 338-E) February 9, 2016 solicitation. 5 The Commission also ordered SCE to make certain changes to its 2014 RPS Procurement Plan and to file a final plan by December 8, On December 8, 2014, SCE filed its final 2014 RPS Procurement Plan. Consistent with the schedule set forth in D , SCE issued its 2014 RFP on December 18, Summary of SCE s Assessment of Portfolio Needs and Preferred Project Characteristics As explained in SCE s 2014 RPS Procurement Plan, SCE had a long-term need for renewable energy in the third compliance period and beyond. Since the filing of its final 2014 RPS Procurement Plan, SCE updated its forecasted RNS with more current information to provide a more accurate depiction of need, and weigh that need against current market trends when formulating its approach for the 2014 RPS solicitation. In the 2014 RPS Procurement Plan, SCE received approval to conduct a targeted solicitation to meet its need for renewable resources. In its 2014 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 and long-term portfolio content category 3 ( Category 3 ) 6 unbundled renewable energy credit ( REC ) products. SCE stated that prior to the start of the term of the contract with SCE, sellers may, at their discretion, deliver energy, capacity or other attributes of the project: (1) through the CAISO market, (2) to a balancing authority, or (3) to a third-party off-taker. SCE also stated that it may, but is not obligated to, purchase any Resource Adequacy benefits attributed to a project while it is delivering energy prior to the commencement of the term of the contract with SCE. SCE required that projects have either a Phase II Interconnection Study or equivalent, a signed interconnection agreement, or an equivalent or better interconnection study, agreement, process, or exemption in order to submit a proposal. Additionally, if the California Environmental Quality Act ( CEQA ) or the National Environmental Policy Act ( NEPA ) applies to the project and a lead agency has been designated under the applicable law, then SCE considered proposals from such projects only if the project had achieved, at a minimum, an application deemed complete (or equivalent) status under the land use entitlement process by the agency designated by CEQA or NEPA as the lead agency. Projects with a contract capacity of 500 kw or greater were eligible to participate in SCE s 2014 RPS RFP. SCE indicated that it continued to solicit ERR 5 D at 124 (Ordering Paragraph 1). 6 As defined in Public Utilities Code Section (b)(3) and D

9 ADVICE 3360-E (U 338-E) February 9, 2016 generating facilities in the Western Los Angeles sub-area of the Los Angeles basin local reliability area to meet local capacity requirements and specifically, resources that are interconnected to SCE s distribution system in the Johanna and Santiago sub-station area to meet SCE s Preferred Resources Pilot goals. For in-state 7 generating facilities that are, or will be, interconnected to the CAISO, SCE required the delivery point to be the 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 the CAISO, SCE required the delivery point to be the intertie point where the seller s transmission provider ties to the CAISO. For out-of-state 8 generating facilities, sellers had to reasonably demonstrate to SCE that the output of the proposed generating facility can in fact be scheduled on an hourly or sub-hourly basis into a California Balancing Authority, without substituting electricity from another source, or dynamically transferred into a California Balancing Authority. SCE decided on the total projected contract energy it signed based on several factors, including projected long- and short-term needs, the impact of reducing federal tax credits, variation in the performance of SCE s existing portfolio, technology resource risk, risk of delay of new projects, risk of new projects not performing as expected, and variation in bundled retail sales, among other factors. 3. The El Cabo Contract Is Consistent with SCE s 2014 RPS Procurement Plan, Portfolio Needs, and Preferred Project Characteristics The El Cabo Contract aligns with the portfolio needs identified in SCE s 2014 RPS Procurement Plan. Specifically, the El Cabo Contract will provide up to the installed capacity of 298 MW of renewable energy from a new wind facility 7 A generating facility was considered in-state if such generating facility s first point of interconnection is, or will be, to the transmission or distribution system of a California Balancing Authority, and the generating facility delivers Category 1 or Category 3 product. 8 A generating facility was considered out-of-state if such generating facility s first point of interconnection is not, or will not be, to the transmission or distribution system of a California Balancing Authority but the generating facility is delivering Category 1 or Category 3 product. Sellers are required comply with all requirements pertaining to Out-of-State Facilities as set forth in the California Energy Commission ( CEC ) RPS Eligibility Guidebook.

10 ADVICE 3360-E (U 338-E) February 9, 2016 starting in 2017 for a twenty-year term, consistent with SCE s long-term renewable procurement need in the third compliance period and beyond. The El Cabo Wind Project also meets all of the eligibility requirements and preferred project and operational characteristics for SCE s 2014 RFP. The generation from the El Cabo Wind Project will be dynamically scheduled into a California Balancing Authority by Seller without substituting electricity from another source, and, thus, the El Cabo Contract is expected to provide a Category 1 product. Additionally, given that the El Cabo Wind Project will be located in New Mexico, its wind profile will be diverse from typical California wind profiles, providing integration benefits to the CAISO operated grid. Additional information is included in Appendix A. 4. The El Cabo Contract is Consistent with SCE s Portfolio Optimization Strategy As described in detail in SCE s 2014 RPS Procurement Plan, 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 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 El Cabo Contract meets the primary objectives of SCE s portfolio optimization strategy. The El Cabo Wind Project is expected to start delivery in December 2017, which will help meet SCE s renewable procurement need in the third compliance period and beyond. Additional information is included in Appendix A. 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

11 ADVICE 3360-E (U 338-E) February 9, 2016 Decisions ). 9 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. Although 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: (1) initial data gathering and validation, (2) a quantitative assessment of proposals, and (3) adjustments to selections based on proposals qualitative attributes. SCE applied these criteria to the proposals received in its 2014 RPS RFP in order to establish a shortlist of proposals from sellers with whom SCE would engage in contract negotiations. Prior to receiving proposals, SCE finalized the shortlist selection criteria with the Independent Evaluator ( IE ). SCE then finalized the major assumptions and methodologies that underlie SCE s valuation, including power price forecast, SCE s existing and forecast resource portfolio, capacity value forecast, renewable integration cost adder ( RICA ) methodology, and capacity limits at interties. 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 proposals for completeness and conformity with the solicitation protocol. The review included an initial screen for required submission criteria such as a Phase II interconnection study or equivalent, evidence of application deemed complete land use entitlement process status as required by the Commission, Geographic Information Systems files as required by the Commission, all SCE required attestations, and other items necessary to deem a proposal complete and conforming. 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. 9 The Commission has also made rulings on various evaluation criteria in its decisions on the IOUs RPS Procurement Plans.

12 ADVICE 3360-E (U 338-E) February 9, 2016 After these reviews, SCE calculated the Renewable Premium and the Net Market Value ( NMV ) 10 for each complete and conforming proposal and ranked the proposals based on this quantitative assessment of costs and benefits. Benefits were composed of separate capacity, energy, curtailment (if applicable), and congestion components (congestion reduction if applicable). Costs included the contract payments, debt equivalents, congestion cost, RICA, and transmission cost. SCE discounted the annual benefit and cost streams to a common base year. The result of the quantitative analysis was a merit order ranking of all complete and conforming proposals by NMV that helped define the shortlist. Following the quantitative analysis, SCE conducted an initial assessment of the qualitative attributes of the top proposals with a competitive NMV. This analysis utilized the Project Viability Calculator to assess certain factors, including the company/development team, technology, and development milestones. Additional attributes such as portfolio fit of commercial operation date, contract term, significant transmission network upgrade costs for projects outside of the CAISO but within California, seller concentration, and resource diversity were also considered in the qualitative analysis. These qualitative attributes were then considered to either eliminate proposals or add projects to the shortlist of proposals, or to break ties, if any. Following its analysis, SCE consulted with its Procurement Review Group ( PRG ) regarding SCE s proposed final shortlist and specific evaluation criteria. SCE then negotiated with the shortlisted sellers for a 90 day period. At the end of the contract negotiation period, SCE sought to execute contracts with the shortlisted sellers with which SCE successfully completed negotiations. SCE s 2014 RPS Shortlist Report was submitted to the Commission on April 23, 2015 in Advice 3209-E. SCE filed a supplement to Advice 3209-E to correct the locations of two projects on May 28, On July 14, 2015, the Commission issued Draft Resolution E-4726 approving SCE s 2014 RPS solicitation shortlist with modifications. On September 3, 2015, SCE filed a second supplemental advice filing to Advice 3209-E to correct its valuation analysis and results. On September 17, 2015, the Commission adopted Resolution E-4726 with no substantive changes to the earlier version. As ordered by Resolution E-4726, SCE filed a Tier 1 Advice Letter on September 28, 2015, re-evaluating proposals from its 2014 solicitation that were interconnected to the Imperial Irrigation District s electrical system such that the differences between the CAISO Tariff 10 Renewable Premium is calculated by subtracting benefits from costs. NMV is calculated by subtracting costs from benefits. The corresponding ranking results are identical, with numerical values only different by sign (positive or negative). SCE generally refers to the NMV throughout the remainder of this Advice Letter.

13 ADVICE 3360-E (U 338-E) February 9, 2016 and Imperial Irrigation District Open Access Transmission Tariff were considered. 11 Using SCE s LCBF methodology, the El Cabo Project compared favorably to other proposals received in the 2014 RPS RFP, as well as other procurement options available to SCE. Additional information is included in Appendix A. 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; (3) Eligibility; and (4) Applicable Law. 13 The remaining non-modifiable terms were converted to modifiable terms. 14 In D , as modified by D , the Commission added two new non-modifiable standard terms and conditions for both bundled contracts and REC-only contracts: (1) Transfer of Renewable Energy Credits; and (2) Tracking of RECs in WREGIS. 15 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. 16 In D , the Commission updated the non-modifiable RECs and Green Attributes term to a modifiable Bioenergy Transactions term. 17 The El Cabo Contract includes all non-modifiable standard terms and conditions for bundled contracts without change as indicated in the table below. NON-MODIFIABLE TERM STC 1: CPUC Approval CONTRACT SECTION NUMBER Exhibit A, definition #55 (See also Section 2.01(a)) CONTRACT PAGE NUMBER Exhibit A, page 5 (Section 2.01(a), page 6). 11 See Advice 3278-E. 12 D at 20 (Ordering Paragraph 1), Appendix A. 13 D at 33 (Ordering Paragraph 1.a). 14 Id. at 34 (Ordering Paragraph 1.b).

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 a 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 Another way is to show the generation from that facility is scheduled into a California balancing authority pursuant to a dynamic transfer agreement between the balancing authority where the generation facility is located and the California balancing authority into which the generation is scheduled. 21 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 requirements for procurement for compliance with the California renewables portfolio standard are met by the procurement D at (Ordering Paragraph 1). 19 Id. 20 Id. at 76 (Ordering Paragraph 1). 21 Id. 22 Id.

15 ADVICE 3360-E (U 338-E) February 9, 2016 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. 23 Pursuant to the provisions set forth in the El Cabo Contract, SCE will procure energy, capacity, and associated renewable energy attributes generated from an ERR that will be dynamically scheduled into a California balancing authority without substituting electricity from another source. In addition, per the El Cabo Contract, the El Cabo Wind Project must obtain and keep current California Energy Commission ( CEC ) certification as an ERR 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 El Cabo Wind 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 El Cabo Contract. Accordingly, this is a Category 1 transaction pursuant to the Public Utilities Code Section (b)(1) and D SCE has not identified a risk that the El Cabo Wind Project will fail to deliver Category 1 RECs. Forecast of Portfolio Balance Requirements 24 PCC 1 Balance Requirement Compliance Period 2 ( ) GWh CP 2 = 65% of RECs applied to procurement quantity requirement CP 3 = 75% of RECs applied to procurement quantity requirement Compliance Period 3 ( ) GWh Quantity of PCC 1 RECs 25 9,523 53, Id. at 80 (Ordering Paragraph 9). 24 SCE s forecast assumes a 100% success rate for projects in development that are not yet online. 25 The Quantity of PCC 1 RECs (under contract, not including proposed contract) represents the total forecasted energy deliveries for all executed RPS-eligible contracts, including seventeen contracts from SCE s 2014 RPS RFP Solicitation, minus the forecasted energy deliveries from the El Cabo Contract.

16 ADVICE 3360-E (U 338-E) February 9, 2016 (under contract, not including proposed contract) Quantity of PCC 1 RECs from proposed contract Quantity of PCC 2 RECs Quantity of PCC 2 RECs from proposed contract (under contract, not including proposed contract) 0 3, PCC 3 Balance Limitation CP 2 = 15% of RECs applied to procurement quantity requirement CP 3 = 10% of RECs applied to procurement quantity requirement Quantity of PCC 3 RECs (under contract, not including proposed contract) Quantity of PCC 3 RECs from proposed contract 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 its retail sales for the immediately prior compliance period. 26 Since there was not a compliance period prior to the D at 98 (Ordering Paragraph 15).

17 ADVICE 3360-E (U 338-E) February 9, 2016 compliance period, the requirement is 0.25 percent of 2010 retail sales for that compliance period. 27 The El Cabo Contract is a twenty-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 added 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 a load-serving entity.... 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 ( CO2 ). 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. 28 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 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 27 Id. at 98 (Ordering Paragraph 16). 28 D at 2-3.

18 ADVICE 3360-E (U 338-E) February 9, 2016 commitment when the LSE enters into a new or renewed contract with a term of five or more years. 29 Pursuant to D , wind generating facilities are deemed EPS-compliant. 30 The El Cabo Wind Project is a wind facility and therefore meets this requirement. 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, Sierra Club, and the California Department of Water Resources. SCE consulted with its PRG during each milestone of the 2014 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 11, 2015, SCE advised the PRG of its proposed shortlist of proposals for its 2014 RPS solicitation. On July 1, 2015, SCE briefed the PRG on the proposed execution of the El Cabo Contract. H. IE The IE for the 2014 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 El Cabo Contract, and other documents exchanged by the parties. The IE also participated in the PRG review. The IE Report is included as Appendix C. III.

21 ADVICE 3360-E (U 338-E) February 9, Quality of Renewable Resource SCE believes that the El Cabo Wind Project will be able to satisfy the terms of the El Cabo Contract. Twelve meteorological towers have been located on the project site for on-site wind resource and energy assessment since Extensive interpretation of years of meteorological data from each tower installed, coupled with national historic wind data and advanced meteorological analytical programs, allow for a thorough site analysis and confidence in generation of expected energy output. 3. Other Resources Required No additional fuel supply is required for the El Cabo Wind Project. C. Development Milestones 1. Site Control Iberdrola has secured 100% site control to support the El Cabo Wind Project, including full site, mitigation property, interconnection access, and authority to build the necessary access roads via direct ownership, as well as leases with public and private parties. 2. Equipment Procurement As of the filing date of this Advice Letter, Iberdrola has not identified any equipment procurement issues that will affect the El Cabo Wind Project s ability to meet the commercial operation date. Major equipment, such as transformers, circuit breakers, disconnect switches, and switchgear needed to construct the El Cabo Wind Project, will be procured after Iberdrola s electrical engineer consultant creates the project specifications for the major materials purchase. The procurement process for this major equipment is scheduled to start in early December The approximate lead times for major materials range from six months for underground medium voltage power cable to thirteen months for substation power transformers. Iberdrola is confident all materials can be procured in time to enable the El Cabo Wind Project to meet the expected commercial operation date under the El Cabo Contract. As the second largest wind developer in the U.S., Iberdrola s procurement department in Portland has extensive experience with sourcing, material procurement, and contract negotiations on wind projects. Iberdrola also

Additional information regarding wind turbine procurement is included in Appendix A. 3. Permitting/Certifications Status Given that the CEC s pre-certification process requires information pertaining to certain technical parameters of the electrical generation equipment (i.e., the wind turbines), Iberdrola will file for CEC pre-certification once it determines the specific turbine model for the El Cabo Wind Project. As discussed above, Iberdrola plans to conduct a solicitation seeking price and equipment proposals from turbine manufacturers. When that solicitation is complete, Iberdrola will file for CEC pre-certification. The El Cabo Wind Project has received all of the major permits that are required in order for the project to achieve the term commencement date. While there are some ministerial permits that are still outstanding, SCE does not anticipate any issues with the project receiving full certification.
