The IRP is a strategic planning tool that presents a framework for resource acquisitions to ensure the Company continues to provide reliable, low-cost service with manageable and reasonable risk to customers. The IRP builds on the Company's prior resource planning efforts and reflects significant advancements in portfolio modeling.and risk analysis. What is the main purpose of the IRP? The mandate for an IRP is to ensure that the Company has, on a long-term basis, an adequate and reliable electrcity supply at the lowest reasonable cost and to ensure that such supply is provided or fulfilled in a timely and planned maner consistent with the long-term public interest. The IRP serves as a strategic roadmap to assist the Company in determning and implementing its long-term resource strategy. In doing so, the IRP accounts for state specific IRP requirements, expected customer resource needs, the current planning environment, corporate business goals and certin commtments made by the Company as par of MEHC' s acquisition of PacifiCorp, including the acquisition of renewable resources. Tallman, Di - 3 Rocky Mountain Power 1 Q. 2 A. 3 4 5 6 7 Q. 8 A. 9 10 11 12 13 14 15 16 17 18 19 20 21 What is the outcome of the IRP process? The outcome of the IRP process is a preferred portfolio that represents a balance of resource additions that meet future customer needs, minimize cost, balance diverse stakeholder interests and address environmental concerns. The Company's IRP includes an action plan that is intended to inform and provide guidance for the Company's resource procurment activities. How do the most recent IRPs address renewable resources? The 2004 IRP was filed with the Idaho Public Utilties Commssion ("Commssion") on Januar 21, 2005, and the Commssion acknowledged the 2004 IRP on August 26,2005. The 2007 IRP was fied with the Commssion on May 30, 2007, and the Commssion acknowledged the 2007 IRP on October 15, 2007. The 2008 IRP was fied with the Commssion on May 29, 2009, and the Commssion acknowledged the 2008 IRP on September 15,2009. Each of these IRPs identifes a need to acquire 1,400 megawatts ("MW) . or more of cost-effective renewable resources.! Indeed, the acquisition of renewable resources is the first action item listed for each such IRP. For example, the 2007 IRP identifies over 2,000 MW of cost-effective renewable resources to be acquired by 2013 and the 2008 IR tagets to acquire an incremental 1,400 MW by 2018, which is consistent with the taget contained in the 2007 IR. By 2018, acquisition of renewable resources reaches 2,540 MW in the 2008 IRP, which includes over 1,400 MW of resources added from 2009 though 2018. 1 Wind-powered generation resources served as the proxy resource in each IRP. Tallman, Di - 4 Rocky Mountain Power 1 Q. 2 3 A. 4 5 6 7 8 9 10 11 12 13 14 Q. 15 16 A. 17 18 19 20 21 22 Do the referenced IRPs address the procurement process for renewable resources? Yes. Generally, each IRP outlines a resource procurement strtegy as par of the IRP action plan.2 The Company procures resources in accordance with the then- curent law, rules, and/or guidelines in each of the states in which PacifiCorp operates. Meaning that if a jursdiction has a requirement to issue a request for proposal ("RFP") then the Company would comply with the reuirement. Specifically, the Company has relied on periodic issuance of RFPs and pursuit of opportnities through bilateral negotiations, contracting with Qualifying Facilties defined by the Public Utilties Regulatory Policies Act of 1978and self- development for the addition of renewable resources to its portolio. Reliance on multiple procurement approaches enables the Company to achieve regulatory compliance and react effectively to market developments. Have other state commisions acknowledged the referenced IRPs and their associated action plan on renewable resource acquisition? Yes. The commssions in Washington, Oregon, and Utah have acknowledged the 2008 IRP. The Wyoming Public Service Commssion adopted Rule 253 in 2009, which requires the.Company to fie an IRP but does not include an acknowledgment proceeding. In California, the Company provides its IRP on an informational basis and is not required to seek acknowledgement. Each state commssion acknowledged the earlier IRPs referenced, with the exception of the Utah commssion for only the 2007 IRP. 2 See 2004 IRP chapter 9,2007 IRP chapter 8 and 2008 IRP chapter 9. Tallman, Di - 5 Rocky Mountain Power 1 Q.In its acknowledgement of the 2004, 2007 and 2008 IRPs, did the 2 Commission object to the acquisition of renewable resources? 3 A.No. In fact, the Commssion noted Staffs support for acquisition of cost- 4 effective renewable resources in the Commssion's 2007 IRP Acceptance of 5 Filng. 6 MEHC Transaction Commitments 7 Q.Please provide an overview of the MEHC transaction commitments related 8 to the acquiition of renewable resources. 9 A.As par of the regulatory approvals related to the acquisition of the Company, 10 MEHC and the Company commtted to: 11 . Bring at least 100 MW of cost-effective wind resources in service within one 12 year of the close of the transaction; 13 . Have 400 MW of cost-effective new renewable resources in the Company's 14 generation portfolio by December 31,2007; and 15 . Reaffir the Company's commtment to acquire 1,400 MW of cost-effective 16 new renewable generation resources. 17 Each of the Wind Resources was acquired consistent with these commtments 18 and, in paricular, in support of the commtment to have 1,400 MW of cost- 19 effective new renewable resources in the portfolio. 20 Wind Resource Acquisitions 21 Q.Please generally describe the Wind Resources. 22 A.Each Wind Resource is an individual project consisting of wind tubine 23 generators ("WTGs" or a "WTG"), an electrcal collector system, access roads, 24 and required communication and control facilties (e.g., meterig, hardware, 25 software, and associated communication circuits). In the case of Seven Mile Hil, Tallan, Di - 6 Rocky Mountain Power 1 2 3 4 5 6 7 8 Q. 9 A. 10 11 Q. 12 A. 13 14 15 16 17 Glenrock and High Plains, the project also included an operations/maintenance ("O&M") building, collector substation and interconnection facilties. While Rollng Hils required its own collector substation, Seven Mile Hil II, Glenrock III and McFadden Ridge I did not. Finally, Rollng Hils, Seven Mile Hil II, Glenrock III, High Plains and McFadden Ridge I did not require the construction of a new interconnection substation; respectively utilizing the Freezeout, Windstar or Foote Creek substations instead. What WTG do the Wind Resources utilze? The General Electric Company ("G.E.") 1.5 MW model SLE WTG. The number ofWTGs at each Wind Resource is shown in the table below. Wind Resource WTGs G.E. Wind 1.5MW Resource WTGs Seven Mile Hil 66 Glenrock 66 Rolling Hils 66 Seven Mile Hil II 13 Glenrock II 26 Hil!h Plains 66 McFadden Ridge I 19 Who owns the land where the Wind Resources reside? The Company is leasing land from private entities and the state of Wyoming for each Wind Resource with the exception of Glenrock, Rollng Hils and Glenrock III. Facilities associated with Glenrock, Rollng Hils and Glenrock III are primarly located on land owned by the Company that was previously used to support coal mining activities. Minor levels of facilties are located on state of Wyoming lands. Tallman, Di - 7 Rocky Mountain Power 1 Q. 2 A. 3 4 5 6 7 8 9 10 11 12 Q. 13 A. 14 15 16 17 18 Q. 19 20 A. 21 Please elaborate on the Company-owned land. The Glenrock, Rollng Hils and Glenrock III resources are all located on property owned by the Company that includes the location of the Company's now reclaimed Dave Johnston coal mine. Mining operations took place from approximately 1958 though September of 2000. After mining operations ceased, the Company reclaimed the land pursuant to its Wyoming administered Federal mining permt. The siting of these renewable resources at this location serves as a testimonial to environmental stewardship and continued asset utilzation for the benefit of customers. This is the only instance I am awar of in the western United States where wind projects have been located at the site of a reclaimed coal mine. What factors does the Company consider before acquiring new resources? The decision as to whether it is in the best interests of customers for the Company to acquire a resource is made after reviewing a detailed overview of the project including the contract support and counterpary guarantees, the risks, the need as established by the IRP, the financial assessment, and the justification of the project. Did the Company follow this general process in the acquisition of each Wind Resource? Yes. The Company followed this process in determning that each Wind Resource is prudent and in the public interest to pursue. Tallman, Di - 8 Rocky Mountain Power 1 Q. 2 3 4 A. 5 6 7 Q. 8 9 A. 10 11 12 Q. 13 14 A. 15 16 17 Q. 18 19 A. 20 21 Was the decision to acquire the Wind Resources consistent with the decision making process the Company has used in adding other renewable resources that have been before this Commission? Yes. Some of the renewable resources that have previously been before this Commssion include the Leaning Juniper I, Marengo, Goodnoe Hills and Marengo II wind-powered generation resources. Did the Company perform an evaluation of the wind potentialfor each Wind Resource? Yes. The Company commssioned a third-par to perform an evaluation of the wind potential for each Wind Resource. The Company's decision to acquire each Wind Resource took into account the technical wind study.3. What other factors did the Company take into consideration when making the decision to acquire each Wind Resource? The Company took into account both quantitative and qualitative factors. The quantitative factors included an economic analysis of the resource. See Confidential Exhibit Nos. 20 through 26. Were the economics of each Wind Resource in line with the alternative undifferentiated power market? Yes. Each Wind Resource compares favorably with the expected non- differentiated power market. See economic analysis results contained in Confidential Exhibit Nos. 20 though 26. 3 The decision to proceed with Seven Mile Hil II was informed by the wind study associated with Seven Mile Hil and the decision to proceed with Glenrock II was informed by the wind studies associated with Glenrock and Rollng Hils. Tallman, Di - 9 Rocky Mountain Power 1 Q. 2 3 A. 4 5 6 7 8 9 Q. 10 A. 11 12 13 14 15 Q. 16 A. 17 18 19 20 21 22 Q. 23 A. What qualitative factors did the Company take into account when making the decision to acquire each Wind Resource? The Company took the following qualtative factors into account: the specifications of the specific Wind Resource; the availabilty of major equipment (e.g., WTGs); the availabilty, or lack thereof, of alternative sites; applicable state and federal tax advantages; the availabilty of a constrction contractor; available infrastructure; termnal value; and the timing of net power cost benefits and renewable energy credits ("RECs"). What is terminal value? Termnal value is the value associated with the right to re-power a resource at cost when the asset reaches the end of its initial economic life. Termnal value includes all aspects of the resource, including its location, favorable land rights, the existence of or favorable location to infrastructure, and other beneficial attributes. Does terminal value apply to each Wind Resource? Yes. While the Company conservatively excluded termnal value in its quantitative analysis of Seven Mile Hil, Glenrock, Rollng Hils, Seven Mile Hil II and Glenrock III, an estimate of termnal value associated with the High Plains Wind Resource can be seen in Table 3 of Confidential Exhibit No. 25 and an estimate of termnal value associated with the McFadden Ridge I Wind Resource can be seen in Table 3 of Confidential Exhibit No. 26. Are there other qualitative factors associated with the Wind Resources? Yes. The Seven Mile Hil II resource is located adjacent to the Seven Mile Hil Tallman, Di - 10 Rocky Mountai Power 1 2 3 4 5 6 7 8 9 10 Q. 11 A. 12 13 14 15 16 17 Q. 18 19 A. 20 Q. 21 A. 22 23 resource and, as such, the Company is able to fuher utilze certin infrastructue that was necessary for the Seven Mile Hil resource. Likewise, similar synergies exist with the Rollng Hils and Glenrock III resources (being adjacent to the Glenrock resource) and the McFadden Ridge I resource being adjacent to the High Plains Wind Resource. This fuher utilzed infrastrcture includes transmission interconnection substations (Freezeout, Windsta and Foote Creek) as well as project transmission assets from High Plains to Foote Creek and from Glenrock to Windsta. In addition, O&M buildings, land rights and roads are furter utilized. What independent benefit will the Windstar substation have? In constrcting the Windstar substation, the Company was able to establish a key point of interconnection that can be used for numerous other third pary requests for interconnection (generation and other). In addition, theWindstar substation now represents the key staring point in Wyoming for the Company's multibilion dollar Energy Gateway transmission project that wil, among other things, facilitate further integration of renewable and non-renewable resources. Wil the Company receive production tax credits ("PTCs") and RECs from each Wind Resource? Yes. Did the Company benefit from any Wyoming specific tax benefits? Yes. The Company benefited from a Wyoming sales tax exemption for each Wind Resource. The benefit was in the form of an avoided cost. The Wyoming sales tax exemption sunsets December 31,2011. Tallman, Di - 11 Rocky Mountain Power 1 Q. 2 3 A. Has the Company obtained a Certificate of Public Convenience and Necessity ("CPCN") for each Wind Resurce? Yes. The Company obtained a CPCN for each Wind Resource from the 4 Wyoming Public Service Commssion. Because each Wind Resource is in 5 Wyoming, application for a lie certificate in Idaho was not required. 6 Update for Most Recent Capacity Factor Projections 7 Q. 8 9 10 A. 11 12 13 14 Q. 15 16 A. 17 18 19 20 21 22 In completing the construction process, did the Company obtain third-party technical studies updating the capacity factor estimates for each Wind Resource? Confidential Exhibit Nos. 27, 28, 29, 30 and 31 are the final build design energy projections for the Seven Mile Hil, Glenrock, Rollng Hils, Seven Mile Hil II and Glenrock III resources, respectively. A final build design energy projection has yet to be completed for the High Plains and McFadden Ridge I resources. Please summarize the final build design energy projections for these resources. The table below provides a summar of the final build design energy.projection estimate ("FBDE") for each Wind Resource as well as the projection at the time the decision was made to acquire the resource. The summar shows estimated annual capacity factor ("CF") at the probability fifty (P50) level and megawatt- hours ("MW"). Because actual CF is dependent on the weather and other factors, a P50 estimate means that the actual production in any given year can be expected to be higher or lower over the life of the resource.

No. As more information is acquired, it is not unusual for capacity factor estimates to be updated. Why were the estimated capacity factors of these resources updted? The update in.estimated capacity factor reflects normal changes that resulted in the final construction design of the resources, as well as additional information on wind climatology for the sites. Is the average capacity factor of the Wind Resources in line with the average capacity factor for the Company's Wyoming power purchase contracts with wind-powered generation resources? Yes. The average capacity factor for the Company's Wyoming power purchase contracts with wind-powered generation resources is approximately 32.0 percent. Tallman, Di - 13 Rocky Mountain Power 1 Q. 2 3 4 A. 5 6 7 8 Q. 9 10 A. 11 12 13 14 Q. 15 A. 16 17 18 19 Q. 20 A. 21 Is the average capacity factor predicted for the Wind Resources in line with the proxy capacity factor assumed for Wyoming wind resources in the Company's IRP? Yes. The Company's 2007 IRP and 2008 IRP used a 35 percenë capacity factor to model proxy wind projects for building the Company's portfolio of renewable energy resources. In reality, some renewable resources wil have capacity factors above 35 percent and others wil be lower than 35 percent. Does the Company currently have wind resurces or contracts with wind resources in its portfolio with capacity factors below 35 percent? Yes, excluding any of the Wind Resources, the Company curently has 21 such resources with projected annual capacity factors below 35 percent. These resources are located inside and outside of Wyoming. See Confidential Exhibit No. 32. Does the net power cost study in this case include the FBDE? Yes. The Company believes the most recent capacity factor projection is appropriate to use for setting rates and, as such, the Company included ~e FBDE updates in the net power cost study sponsored by Company witness Dr. Hui Shu in this case. Has the Company included the value of PTCs and RECs in its filing? Yes. The value of PTCs, RECs or other known tax-related benefits and burdens for each Wind Resourc are included in the Company's filng. 435% is in line with the proxy wind assumptions used in the 2004IRP. Tallman, Di - 14 Rocky Mountan Power 1 Q. 2 3 4 A. Did the Company acquire the Wind Resources for the purpose of complying with renewable portfolio standards in Oregon, Washington, Calornia or to meet the requirements of carbon reduction legislation in Utah? No, each Wind Resource was acquired on the basis of its economics, other 5 quantitative factors and qualitative factors. 6 Conclusion 7 Q. 8 A. 9 10 11 12 13 14 15 16 17 Q. 18 A. 19 20 21 22 23 What are the overall benefits of Wind Resources to Idaho customers? Customers benefit from the Wind Resources because they represent cost effective renewable resources. The 2004, 2007 and 2008 IRPs specify that cost effective renewable resources (using wind-powered generation resources as a proxy) should be steadily added to the system. The Wind Resources benefit customers as their acquisitions were both cost effective and consistent with th~ Company's robust long-term planning efforts though the IRP process. Customers furter benefit from these renewable resources because they provide a zero incremental cost fuel source, thus reducing exposure to potentially volatile commodity and/or fuel risks. Are there other benefits the Commission should consider? Yes. The Wind Resources are multi-shafted generation resources that diversify the impact of individual generator failures and provide the Company with continued ownership and operational experience with utility-scale wind projects. Each Wind Resource utilizes G .E. wind tubines, thus complementing the Company's operating experience with other G.E. based projects, spare optimization and procurement of O&M services. Tallman, Di - 15 Rocky Mountan Power 1 Q.Was each Wind Resource acquired consistent with the Company's then- 2 current IRP and does it represnt the least cost/rik option available for the 3 long-term benefit of customers? 4 A.Yes 5 Q.Was each Wind Resource prudently acquired, in the public interest and is 6 each Wind Resource used and useful? 7 A.Yes 8 Q.Does this conclude your direct testimony? 9 A.Yes.
