PAC-07- DIRECT TESTIMONY OF TERRI CARLOCK IDAHO PUBLIC UTILITIES COMMISSION SEPTEMBER 28, 2007 please state your name and address for the record. My name is Terri Carlock.My business address is 472 West Washington Street, Boise, Idaho. By whom are you employed and in what capacity? I am employed by the Idaho Public Utilities Commission as the Deputy Administrator of the Utilities Division responsible for the Accounting/Audit Section. Please outline your educational background and experience. I graduated from Boise State University in 1980, with B. B.A. Degrees in Accounting and Finance. have attended various regulatory, accounting, rate of return, economics, finance and ratings programs. chaired the National Association of Regulatory Utilities Commissioners (NARUC) Staff Subcommittee on Economics and Finance for more than 3 years.Under this subcommittee, I also chaired the Ad Hoc Committee on Diversification. I am currently the Vice-Chair of the NARUC Staff Subcommittee on Accounting and Finance.I have been a presenter for the Institute of Public Utilities at Michigan State University and for many other conferences. Since joining the Commission Staff in May 1980, I have participated in audits, performed financial analysis on various companies, and have presented testimony before CASE NO. PAC-07- 09/28/07 CARLOCK, T (Di) STAFF this Commission on numerous occasions. What is the purpose of your testimony in this proceeding? The purpose of my testimony is to discuss policy positions, the Multi-State Process, Renewable Energy Credits and present the Staff I s recommendation related to the overall cost of capital for Rocky Mountain Power to be used in the revenue requirement in this case. I will address the appropriate capital structure, cost rates and the overall rate of return. Please summarize your testimony. Portions of my testimony are policy related and do not have specific recommendations directly impacting the revenue requirement.I discuss Renewable Energy Credits (RECs) in my testimony, and I recommend recognizing additional REC revenues of $4,270,923 (system) that reduce the Idaho revenue requirement by $269,344.In my testimony on the overall rate of return, I am recommending a return on common equity in the range of 9.5% - 10.5% with a point estimate of 10.25%.The recommended overall weighted cost of capital is in the range of 7.889% - 8.393% with a point estimate of 8.267% to be applied to the rate base for the test year. Are you sponsoring any exhibits to accompany your testimony? CASE NO. PAC-E- 07-09/28/07 CARLOCK, T (Di) 2 STAFF Yes, I am sponsoring Staff Exhibit No. 120 and Staff Exhibit No. 121 consisting of 3 schedules. Please identify the REC or green tag adj ustments made by Staff in this case. Staff has made two adj ustments to properly reflect REC or green tag revenues.The first imputes revenue for RECs associated with maj or new wind proj ects. The second is a proforma adjustment to better reflect REC revenue credits from sales during the adj usted test period. Please explain the adj ustment to impute revenues associated with maj or new wind proj ects. PacifiCorp assumes that there will be RECs with the energy generated by the Wolverine Creek , Leaning Juniper , Marengo and Goodnoe Hills proj ects.In the Integrated Resource Plans, the Company s economic analysis uses the sale of RECs to show the economic feasibili ty of the wind proj ects for inclusion in the system resource portfolio.Staff utilized and accepted use of these REC revenues to fully accept the inclusion of these plants in rate base and all associated costs in the revenue requirement.The associated REC revenues shown on Staff Exhibit No. 120 are required to make these specific wind proj ects cost effective.To compute the total REC value, Staff multiplied the Company s assumed CASE NO. PAC-E- 07- 09/28/07 CARLOCK , T (Di) 3 STAFF value of RECs by the generation for each proj ect for the time period reflected during the proformed 2007 period. These revenues need to be imputed to properly reflect all the components to justify inclusion of these plants in customer rates.The total REC values for these proj ects are $3,445,533 (system). Please explain the proforma adjustment to better reflect REC revenue credits from sales during the adj usted test period. The proforma test year adj ustment reflects a known and measurable adjustment.The 2007 REC revenues through May amounts to $1,837,075 (system) while the amount booked in 2006 was $1 011,684 (system).The difference of $825 390 (system) is the conservative proforma adjustment recommended by Staff.The adj ustment is conservative since REC sales in prior years were also made in the last two quarters of the year but the 2007 comparison does not include these quarters. What is the total adjustment made by Staff for REC revenue credits? The total of these two adj ustments $4,270,923 (system).Both adjustments would be allocated using the system generation factor of 6.306%, resulting in a reduction of $269,344 in the Idaho revenue requirement. CASE NO. PAC-07- 09/28/07 CARLOCK, T (Di) 4 STAFF Have you reviewed the testimony and exhibits of Rocky Mountain Power witnesses Hadaway and williams associated with the return components? Much of the theoretical approach used byYes. witnesses Hadaway and Williams in their testimonies and exhibits is generally the same as I have used. judgment in some areas of application results in different outcomes. What legal standards have been established for determining a fair and reasonable rate of return? The legal test of a fair rate of return for a utility company was established in the Bluefield Water Works decision of the United States Supreme Court and is repeated specifically in Hope Natural Gas. In Bluefield Water Works and Improvement Co. v. West Virginia Public Service Commission, 262 U. S. 679, 692, 43 S.Ct. 675, 67 L.Ed. 1176 (1923), the Supreme Court stated: A public utility is entitled to such rates as will permit it to earn a return on the value of the property which it employs for the convenience of the public equal to that generally being made at the same time and in the same general part of the country on investments in other business undertakings which are attended by corresponding risks and uncertainties but it has no constitutional right to profits such as are realized or anticipated in highly profitable enterprisesor speculative ventures. The return should be reasonably sufficient to assure confidence CASE NO. PAC-07-09/28/07 CARLOCK, T (Di) 5 STAFF in the financial soundness of the utility and should be adequate, under efficient and economical management, to maintain and support its credit and enable it to raise the money necessary for the proper discharge ofits public duties. A rate of return may be reasonable at one time and become too high or too low by changes affecting opportunities for investment , the money market and businessconditions generally. The Court stated in FPC v. Hope Natural Gas Company, 320 S. 591, 603, 64 S.Ct. 281, 88 L.Ed. 333 (1944) : From the investor or company point of view it is important that there be enough revenue not only for operating expenses but also for thecapital costs of the business. These include service on the debt and dividends on thestock. . .. By that standard the return to the equity owner should be commensurate with returns on investments in other enterprises having corresponding risks. That return , moreover, should be sufficient to assure confidence in the financial integrity of the enterprise, so as to maintain its credit and to attractcapital. (Citations omitted. The Supreme Court decisions in Bluefield Water Works and Hope Natural Gas have been affirmed in In re Permian Basin Area Rate Case, 390 U.S. 747 , 88 S.Ct 1344, 20 L.Ed 2d 312 (1968), and Duquesne Light Co. v. Barasch, 488 U. S. 299, 109 S.Ct. 609, 102 L.Ed.2d. 646 (1989) . The Idaho Supreme Court has also adopted the principles established in BluefLeld Water Works and Hope Natural Gas.See In re Mountain States Tel. Tel. Co. 76 Idaho 474 , 284 P.2d 681 (1955) i General Telephone Co. v. IPUC, CASE NO. PAC-07-09/28/07 CARLOCK, T (Di) 6 STAFF 109 Idaho 942, 712 P.2d 643 1986); Hayden Pines Water Company v. IPUC, 122 ID 356, 834 P.2d 873 (1992). As a result of these United States and Idaho Supreme Court decisions, three standards have evolved for determining a fair and reasonable rate of return: (1) The Financial Integrity or Credit Maintenance Standard;(2) the Capital Attraction Standard; and, (3) The Comparable Earnings Standard.If the Comparable Earnings Standard is met, the Financial Integrity or Credit Maintenance Standard and the Capital Attraction Standard will also be met, as they are an integral part of the Comparable Earnings Standard. Have you considered these standards in your recommendation? These criteria have been seriouslyYes. considered in the analysis upon which my recommendations are based.It is also important to recognize that the fair rate of return that allows the utility company to maintain its financial integrity and to attract capital is established assuming efficient and economic management, as specified by the Supreme Court in Bluefield Water Works. Please summarize the parent/subsidiary relationships for Rocky Mountain Power. Rocky Mountain Power I s common stock is not CASE NO. PAC-07-09/28/07 CARLOCK, T (Di) 7 STAFF traded.Rocky Mountain Power is a division of PacifiCorp and PacifiCorp is a wholly owned subsidiary of MidAmerican Energy Holdings Company (MEHC).Due to thi parent/subsidiary relationship there is no direct equity market data available for utility operations at Rocky Mountain Power or PacifiCorp. What approach have you used to determine the cost of equity for Rocky Mountain Power? I have primarily evaluated two methods:the Discounted Cash Flow (DCF) method and the Comparable Earnings method. Please explain the Comparable Earnings method and how the cost of equity is determined using this approach. The Comparable Earnings method for determining the cost of equity is based upon the premise that a given investment should earn its opportunity costs. competitive markets, if the return earned by a firm is not equal to the return being earned on other investments of similar risk, the flow of funds will be toward those investments earning the higher returns.Therefore , for a utility to be competitive in the financial markets, it should be allowed to earn a return on equity equal to the average return earned by other firms of similar risk. The Comparable Earnings approach is supported by the CASE NO. PAC-07- 09/28/07 CARLOCK , T (Di) 8 STAFF Bluefield Water Works and Hope Natural Gas decisions as a basis for determining those average returns. Industrial returns tend to fluctuate with business cycles, increasing as the economy improves and decreasing as the economy declines.Utility returns are not as sensi ti ve to fluctuations in the business cycle because the demand for utility services generally tends to be more stable and predictable.However, returns have fluctuated since 2000 when prices in the electricity markets dramatically increased.Electrici ty prices have not seen the dramatic spikes lately so earnings are more stabile. Please evaluate interest rate trends. The prime interest rate has increased since the last PacifiCorp rate case but has decreased from 8.25% to the current rate of 7.75%.The federal funds rate and other rates have also decreased this year. Please provide the current index levels for the Dow Jones Industrial Average and the Dow Jones Utility Average. The Dow Jones Industrial Average (DJIA) closed 13,878 on September 26 2007.The DJIA all-time high 14,000.was reached on July 19,2007.The Dow J one s Utility Average closed at 512 September 26,2007. Please explain the risk differentials between CASE NO. PAC-07-09/28/07 CARLOCK, T (Di) 9 STAFF industrials and utilities. Risk is a degree of uncertainty relative to a company.The lower risk level associated with utilities is attributable to many factors even though the difference is not as great as it used to be.Utili ties continue to have limited competition for distribution of utility services within the certificated area.With limited competition for regulated services , there is less chance of losses related to pricing practices, marketing strategy and advertising policies.The competitive risks for electric utilities have changed with increasing non- utili ty generation, deregulation in some states, open transmission access, and changes in electricity markets. However , competitive risks are limited for Rocky Mountain utili ty operations.The demand for utility services is relatively stable and certain or increasing compared to that of unregulated firms and even other utility industries. Competitive risks continue to be lower for Rocky Mountain Power and PacifiCorp than for many other electric companies primarily because of the low-cost source of power and the low retail rates compared to national averages.The risk differential between Rocky Mountain Power and PacifiCorp and other electric utilities is based on the resource mix and the cost of CASE NO. PAC-E- 07 - 5 09/28/07 CARLOCK, T (Di) 10 STAFF those resources.All resource mixes have risks specific to resources chosen.The demand for electric utility services of Rocky Mountain Power and PacifiCorp is increasing at predictable rates.This low demand risk is partially due to the low-cost power and the customer mix of the power users. Under regulation , utilities are generally allowed to recover through rates, reasonable, prudent and justifiable cost expenditures related to regulated services.Unregulated firms have no such assurance. Utilities in general are sheltered by regulation for reasonable cost recovery risks, making the average utility less risky than the average unregulated industrial firm. Considering all of these comparisons, I believe a reasonable return on equity attributed to Rocky Mountain Power and PacifiCorp is 10.0% - 11.0% under the Comparable Earnings method. You indicated that the Discounted Cash Flow method is utilized in your analysis.Please explain this method. The Discounted Cash Flow (DCF) method is based upon the theory that (1) stocks are bought for the income they provide (i. e., both dividends and/or gains from the sale of the stock), and (2) the market price of stocks CASE NO. PAC-07-09/28/07 CARLOCK, T (Di) 11 STAFF equals the discounted value of all future incomes.The discount rate, or cost of equity, equates the present value of the stream of income to the current market price of the stock.The formula to accomplish this goal is: -------------- (l+ks ) 1 ( 1 + ks ) 2 +...+ ------ + ------ (l+ks ) N (l+ks ) N Po =Current Price Di vidend ks =Capitalization Rate, Discount Rate, or Required Rate of Return Latest Year Considered The pattern of the future income stream is the key factor that must be estimated in this approach.Some simplifying assumptions for ratemaking purposes can be made without sacrificing the validity of the results. Two such assumptions are:(1) dividends per share grow at a constant rate in perpetuity and (2) prices track earnings.These assumptions lead to the simplified DCF formula , where the required return is the dividend yield plus the growth rate (g): ks = - - - + g Have you factored flotation costs in with your cost of capital analysis? Yes, I have considered direct flotation costs CASE NO. PAC-07-09/28/07 CARLOCK , T (Di) 12 STAFF in my analysis by increasing the dividend yield component of the DCF analysis.Because only direct costs should be considered, I have used a flotation factor of 4% with 2% assigned to the utility operations.This practice continues to be reasonable because all subsidiaries of MEHC should be responsible for some of the actual flotation costs.I have therefore adj usted the DCF formula to include the direct flotation costs as "df" ks = (- - - (1 + df) J + g What is your estimate of the current cost of capital for Rocky Mountain Power and PacifiCorp using the Discounted Cash Flow method? The current cost of equity capital for Rocky Mountain Power and PacifiCorp, using the Discounted Cash Flow method with comparable companies is between 7.7% - 11.7%.Due to ongoing capital requirements, I believe a dividend yield of 4.2% with an average growth rate of 2% is reasonable and representative resulting in a DCF return on equity of 9.4%. How is the growth rate (g) determined? The growth rate is the factor that requires the most extensive analysis in the DCF method.It is important that the growth rate used in the model be consistent with the dividend yield so that investor CASE NO. PAC-E- 07 - 5 09/28/07 CARLOCK, T (Di) 13 STAFF expectations are accurately reflected and the growth rate is not too large or too small. I have used an expected growth rate of 4% - 6%. This expected growth rate was derived from an analysis of various historical and proj ected growth indicators, including growth in earnings per share, growth in cash di vidends per share, growth in book value per share, growth in cash flow and the sustainable growth. What is the capital structure you have used for Rocky Mountain Power and PacifiCorp to determine the overall cost of capital? I have utilized the embedded capital structure at December 31 , 2007 consisting of 49.1% debt, 0. preferred stock and 50.4% common equity as shown on Schedule 3 of Staff Exhibit No. 120.Rocky Mountain Power witness Williams reflects this capital structure in his testimony on page I have accepted the proforma capital structure recommended by Rocky Mountain Power in this case because the proforma changes are adequately known to be included as a known and measurable adj ustment in this case and it represents a capital structure consistent with the rate base investment included in the Staff revenue requirement. What are the costs related to the capital structure for debt and preferred stock? CASE NO. PAC-07- 09/28/07 CARLOCK, T (Di) 14 STAFF I have evaluated and accepted the embedded cost rates used in williams Exhibit Nos. 7 - 10.The cost of debt is 6.26% (Staff Exhibit No. 120, Schedule 1) and the cost of preferred stock is 5.41% (Staff Exhibit No. 120, Schedule 2) . You indicated the cost of common equity range for Rocky Mountain Power and PacifiCorp is 10.0% - 11. under the Comparable Earnings method and 7.7% - 11. under the Discounted Cash Flow method.What is the cost of common equity capital you are recommending? The fair and reasonable cost of common equity capi tal I am recommending for Rocky Mountain Power and PacifiCorp is in the range of 9.5% - 10.5%.Although any point within this range is reasonable, the return on equity granted would not normally be at either extreme of the fair and reasonable range.I utilized a point estimate of 10.25% in calculating the overall rate of return for the revenue requirement. What is the basis for your point estimate being 10.25% when your range is 9.5% - 10. 5%? The 10.25% return on equity point estimate utilized is based on a review of market data and comparables, average risk characteristics for Rocky Mountain Power and PacifiCorp, including past and current impacts in state jurisdictions, operations and the CASE NO. PAC-07- 09/28/07 CARLOCK, T (Di) 15 STAFF capital structure. What is the overall weighted cost of capital you are recommending for Rocky Mountain Power and PacifiCorp? I am recommending an overall weighted cost of capital in the range of 7.889% - 8.393%.For use in calculating the revenue requirement, a point estimate consisting of a return on equity of 10.25% and a resulting overall rate of return of 8.267% was utilized as shown on Schedule 3, Staff Exhibit No. 120. Have you reviewed all of the Staff recommendations in this case to evaluate if they are consistent with Revised Protocol? Yes, I have and I believe all of the recommended Staff adjustments are consistent with Revised Protocol. Are there Multi - State Process (MSP) or Revised Protocol items that have influenced Staff recommendations in this case? All Staff recommendations took intoYes. consideration, and were therefore influenced by, Revised Protocol to ensure they were consistent.There are items where absent the MSP process and Revised Protocol, Staff may have made different or additional adjustments. CASE NO. PAC-07-09/28/07 CARLOCK, T (Di) 16 STAFF Please explain the first area where you believe differences would have likely occurred. Absent the Revised Protocol, the treatment of Monsanto by Staff would have likely been different. Staff would have likely continued to treat Monsanto completely as a system customer.Staff treatment for all ancillary services where Monsanto and irrigators were given credits would have likely been treated the same as Staff proposes in this case, i. e. as system resources. Revised Protocol allows the costs to serve these customer contracts to be completely allocated to Idaho using dynamic system allocation factors.The bill credi t provisions for Monsanto are treated similar to ancillary power supply contacts where they are allocated among states on the same basis as system resources. Staff witness Lanspery proposes the Irrigation Credits be allocated the same as ancillary power supply contacts. The credits to Monsanto and Irrigation customers are given for various ancillary services as set out in the contacts.These ancillary services provide system benefits that are dispatchable by the Company or predetermined by contract thus avoiding the need for additional resources or duplicative services if these contracts were not in place. CASE NO. PAC-07-09/28/07 CARLOCK , T (Di) 17 STAFF I am pointing out these differences to help explain the thought process as I evaluated the consistency and reasonableness of Staff I s positions under Revised Protocol.The Company and all customers continue to receive system benefits from these ancillary services set forth in the contracts.A reasonable price is paid for these services based on market evaluations that are utilized throughout the PacifiCorp models and system operations.The Revised Protocol treatment allows Idaho Commissioners to establish reasonable rates for Idaho customers and it also avoids having Idaho customers pay for any incentive or economic development rates that may be established in other states.To summarize, the Revised Protocol allocation retains the benefits, assures only reasonable costs are being allocated and most of all leaves the rate decisions for Idaho customers with the Idaho Commission without negatively impacting other states. Are there additional adjustments or issues Staff would have discussed absent the Revised Protocol? Yes, there are areas where Staff would have likely proposed specific regulatory treatment or adjustments absent the MSP process and Revised Protocol. These areas include the regulatory treatment and cost allocation for hydro decommissioning and abandonment; the CASE NO. PAC-07-09/28/07 CARLOCK, T (Di) 18 STAFF cost prudence of resource choices in general and under Resource Portfolio Standards (RPS); and green tag revenues in addition to the adjustment discussed previously.These additional issues would not have a material revenue requirement impact if they were proposed in this case.In fact I believe the revenue requirement could have been offset by the increasing and decreasing impacts since the rate impacts from these issues are just beg inning.Future rate cases and the resulting impacts are where the regulatory treatment will become more important to customers. The MSP Standing Committee and workgroup participants are evaluating these issues.I f recommended clarifications, modifications or additions to the Revised Protocol are developed; they will be presented to the various Commissions for approval.If agreement between the states is not achieved, a different process will be followed to bring issues before the Commission.Each state could have different proposals for regulatory treatment presented.Disjointed treatment in different states may have a negative impact on system planning and/or operations and would need to be evaluated at that time. If additional adjustments are not being proposed in this case, why discuss these items? CASE NO. PAC-07-09/28/07 CARLOCK , T (Di) 19 STAFF These items are discussed for identification purposes.It allows parties in this case that haven I been participating in the MSP workgroup process to be aware of these current and future issues to evaluate future participation levels. Please generally describe the issue associated with hydro decommissioning and abandonment. The Regional Resources category in the Revised Protocol includes the Hydro-Endowment for owned hydro resources and Mid-Columbia contracts.The allocation methodology utilizes an Embedded Cost Differential (ECD) adjustment to attribute hydro benefits and costs to the region, West or East, where hydro resources originated. The calculation of the ECD when hydro proj ects are decommissioned or abandoned is the issue.For example, the Powerdale Hydroelectric Facility was decommissioned for economic reasons following a flood.One reason it was more economic to decommission the facility than to repair it was timing.This facility was part of a settlement agreement to decommission so there was insufficient time before the settlement date for decommissioning to allow repairs to be economic.These circumstances were discussed in Case No. PAC-07-4 and Order No. 30344.The discussion topic for MSP evaluation needs to focus on the intent behind the continuation of CASE NO. PAC-07-09/28/07 CARLOCK , T (Di) 20 STAFF the hydro-endowment concept in Revised Protocol.The West (the original Pacific Power system) wanted to continue to receive the benefits of the low cost hydro system in the West and was willing to pay costs associated with the hydro system including relicensing costs if they were more expensive , above embedded costs. Settlements to decommission are part of the relicensing process.The intent behind the hydro-endowment along with the ECD formula needs to be evaluated to assure they remain consistent when hydro facilities are decommissioned or abandoned.This includes evaluating costs above the embedded cost.The embedded cost should be calculated for ECD comparison purposes in the hydro- endowment without marginal new resources, including wind, being added to the embedded costs.This will allow the higher costs for relicensing to follow hydro benefits. Please generally describe issues related to resource choices in general and under Resource Portfolio Standards (RPS). Resource choices in general and under RPS requirements are topics being explored in the MSP Resource Choice workgroup.The workgroup is evaluating issues that may impact cost allocations.Areas of concern with workgroup participants range from no concern, to concern when different resource preferences CASE NO. PAC-07- 09/28/07 CARLOCK, T (Di) 21 STAFF emerge among states.Workgroup participants note that the Revised Protocol does address divergent resource portfolio standards in the event that a state chooses a higher cost resource than contained in the IRP.Some workgroup participants note that the resulting operational effects could remain a problem.In addition the Revised Protocol language may not cover scenarios where a state did not choose a different resource but rej ected a resource in the Integrated Resource Plan or Request for Proposal.The workgroup is ongoing. What Renewable Energy Credit or Green Tag issues are being discussed within MSP? As Renewable Portfolio Standards are established in numerous states, the availability of renewable resources and/or Renewable Energy Credits, RECs, to meet those requirements becomes an issue.RECs or Green Tags are tradable commodities even though the market isn't very liquid.Most terms and conditions associated with REC transactions are established in bilateral contracts.RECs represent the environmental green" attributes associated with the generation of one megawatt-hour of renewable energy from an eligible renewable resource.Since the state RPS requirements differ , the need and regulatory treatment may not be consistent even between states with RPS requirements. CASE NO. PAC-07- 09/28/07 CARLOCK, T (Di) 22 STAFF In states where RPS requirements have not been established, such as Idaho, the issue is slightly different.Meeting RPS requirements means that RECs will not be sold in the same manner as they were previously sold and the associated revenue credit dollars to Idaho will most likely decline.Available RECs will only be sold when they are not needed to meet RPS requirements. An allocation methodology is needed to provide revenue credits to states that have available RECs allocated to it and charge states for the transfer of needed RECs. This is one way to maintain or enhance the revenue stream associated with RECs in states where RPS requirements haven t been established and provide a win-win scenario for all customers. Another issue deals with the actual revenue credits from the sale of RECs.Unless the allocation of REC sales revenue is changed to be more closely aligned with the states that have RECs available for sale, the revenue credits will go to all customers in the system rather than customers in states with available RECs. These are issues also being discussed wi thin the ongoing MSP and workgroup meetings. Does this conclude your direct testimony in this proceeding? Yes, it does. CASE NO.
