9 II. ASSIGNMENT AND SUMMARY OF TESTIMONY AND RECOMMENDATIONS 0 Q. What is your assignment in this proceeding? A. I am supporting SPS s request to recover long-term PPA costs. There are two major components of purchased power costs: capacity costs and energy costs. Some of SPS s PPAs also include other components of cost such as variable operation and maintenance ( O&M ) costs, start costs, and dispatchability payments. For SPS s Texas retail jurisdiction, capacity and other non-fuel related costs are recovered in base rates. In my testimony, I support recovery of capacity and non-fuel related costs incurred under PPAs. Specifically in my testimony, I will address the following: SPS s long-term purchased power procurement activities and administration of long-term PPAs; and the specific capacity-related costs incurred under PPAs that SPS seeks to recover in base rates and the reasonableness of the costs. 0 Finally, I sponsor or co-sponsor the following Rate Filing Package ( RFP ) Schedules and the portions of the Executive Summary that contain information from these Schedules or regarding long-term PPAs: H-.a, H-.c, I-., I-, I-, I-, I-, I-0(V)(CD), I-, I-, I-, and Q-.. Q. Will your testimony be updated for actual costs incurred in the three months following the Test Year, October 0 through December 0? A. No. As discussed by SPS witness Evan D. Evans, SPS will file an update days after SPS filed this application. The update will include actual costs incurred to replace the estimates provided in the application for the period of October, 0 through December, 0, referred to as the Update Period. No estimates for Klein Direct Revenue Requirement Page RR - Page of 0 0

10 the Update Period are included in this testimony, therefore, it is not necessary to update expenses for this timeframe. The requested capacity-related PPA costs represent costs to be incurred in the Rate Year, which is the twelve months starting August, 0 ( Rate Year ), as determined by the costs incurred during October, 0 through September 0, 0 ( Test Year ) adjusted for known and measurable changes. Q. Please summarize the key points, recommendations, and conclusions in your testimony. A. Long-term Power Purchase Process and Practices 0 SPS purchases capacity and associated energy under long-term agreements, and administers those agreements to provide its customers with the lowest reasonable cost of power available. SPS uses a number of strategies to ensure that it obtains the lowest reasonable cost of power, and then implements a monthly invoice verification process to verify the accuracy of each invoice. SPS continually updates and improves its process and practices by conducting a review after each solicitation and negotiation. 0 0 Long-term Purchased Power Contracts and Costs All capacity-related costs that SPS incurred during the Test Year were incurred under contracts reviewed in previous base rate cases and fuel reconciliations. Given SPS s need for capacity in 0-0, it was reasonable to make these capacity purchases. SPS reasonably incurred $0,0, (total SPS before jurisdictional allocations, Total Company or total company ) in capacity-related PPA costs during the Test Year. Due to contractually authorized price increases, a PPA termination, changes in operational status, and a change in tested heat rate, pro forma adjustments need to be made to the Test Year data for these known and measurable changes. Capacity-related PPA costs will increase in 0 by $,,0 (total company). The total amount SPS seeks to recover through base rates for capacity-related costs incurred under PPAs is $,, (total company). Klein Direct Revenue Requirement Page 0 RR - Page of 0 0

11 Incurring these costs is reasonable and necessary to provide SPS s customers with reliable electric service. 0 0 Q. Please describe the information in the H-. series schedules that you sponsor or co-sponsor. A. I co-sponsor Schedules H-.a and c, which summarize Purchased Power Data. SPS witness Jennifer S. Pytlik co-sponsors these schedules. I sponsor the data within the schedules that report the companies with which SPS has long-term PPAs, and the Net MWh (H-.a) and Fixed Costs (H-.c) that resulted from each of the agreements during the Test Year. The data is given by month and totaled for the Test Year. Q. Please describe the information in the I series schedules that you sponsor or co-sponsor. A. I co-sponsor Schedule I-. which addresses non-recurring fuel and purchased power expenses. SPS witness H. Craig Romer also co-sponsors the schedule. I sponsor the schedule as it relates to long-term purchased power expenses. SPS had no such expenses during the Test Year. I co-sponsor Schedule I- which addresses fuel and purchased power procurement practices, and Schedule I- which describes the fuel and purchased power committees. Mr. Romer also co-sponsors these schedules. Mr. Evans and SPS witness Bennie F. Weeks also co-sponsor Schedule I-. Together, these schedules discuss the process for assessing, reviewing, and engaging in transactions regarding fuel and purchased power procurement. I sponsor these schedules as they relate to long-term purchased power expenses. Klein Direct Revenue Requirement Page RR - Page of 0 0

12 I co-sponsor Schedules I- and I- with Mr. Romer. Schedule I- pertains to fuel and fuel-related contracts and presents summaries of such contracts. The workpapers to this schedule contain the contracts. Schedule I- pertains to a list of fuel or purchased-power related contracts under which costs were incurred. SPS has not filed a fuel reconciliation with its current base rate case. Consequently, the schedules and workpapers present only the contracts 0 0 with variable O&M charges and other non-fuel PPA charges because those are the contracts that have costs that impact base rates. I sponsor the long-term purchased power portion of these schedules and workpapers. I co-sponsor Schedule I-, which presents employee organizational charts, and Schedule I-0(V)(CD), which presents employee ethics documents. Mr. Romer, Ms. Weeks, and Mr. Evans also co-sponsor these schedules. SPS witness Carol C. Bouw also co-sponsors Schedule I-0(V)(CD). I sponsor the purchased power portion of the organization chart and the employee ethics documents as they pertain to these employees. I co-sponsor Schedule I-, which pertains to the methods, assumptions, and sources of information used to determine reasonably predictable fuel and purchased power costs. Mr. Evans also co-sponsors this schedule. I sponsor the portion of the schedule that pertains to long-term purchased power. I co-sponsor Schedule I-, which discusses activities intended to reduce fuel, fuel-related or purchased power energy costs. SPS witness William A. Grant As discussed by Mr. Evans, SPS is not filing a fuel reconciliation with this base rate case in accordance with the Order in Project No. 0 and Tex. Admin. Code. as revised in that project.

14 III. LONG-TERM POWER PURCHASE PROCESS AND PRACTICES 0 Q. What is SPS s goal in entering into long-term PPAs? A. SPS is committed to purchasing power and energy under long-term agreements, and administering those agreements, to provide its customers with the lowest reasonable cost of power available consistent with predicted market conditions, power supply reliability, system reliability, and electric system constraints. Q. What strategy has SPS employed to accomplish this goal? A. SPS works to accomplish this goal through the selection of suppliers as well as the execution and administration of the PPAs. Ms. Weeks discusses the work done by Resource Planning to accomplish this goal. After Resource Planning has selected the preferred bid(s), the Purchased Power group works to achieve the lowest reasonable cost of power purchases for SPS s customers through the negotiation and administration of the final PPA(s). Important elements of this work include the following: 0 Develop Contracts in a Timely Manner. SPS has found that, in order to maintain the viability of power supply proposals through the contract development process, power supply proposals need to be evaluated and contracts developed and executed with the winning bidder(s) within a reasonable time. Include Pay-for-Performance Provisions in Contracts. SPS has attempted, where feasible in contract negotiations, to align the interests of its power suppliers with those of SPS and its customers by including pay-for-performance provisions, such as availability factor adjustments to capacity payments. Maintain Risk and Price as Proposed. SPS ensures that through the contract negotiation process, the level of risk and price proposed in the bid is maintained or improved for the benefit of SPS customers. Prudent Administration. SPS works to ensure that the contracts are prudently administered, including ensuring that the suppliers deliver Klein Direct Revenue Requirement Page RR - Page of 0 0

15 power based on the terms of the PPA throughout the contract period, and that each PPA invoice is accurate. Q. Please describe how SPS verifies the accuracy of each long-term PPA invoice. A. Through coordination between Purchased Power and Commercial Accounting Services personnel, SPS has implemented monthly invoice verification procedures to: 0 compare invoiced deliveries with the SPS revenue-meter readings or scheduled quantities, as applicable for each PPA; confirm that the invoice pricing complies with the applicable provisions of the contract; and check that the invoice calculations are mathematically correct. 0 Q. Does SPS periodically review its power purchase process and practices to improve their effectiveness? A. Yes. After each power purchase solicitation and negotiation is completed, SPS incorporates lessons learned from that process into the next power purchase solicitation and negotiation process to make it more effective. Typical improvements include changes to the forms that SPS requires bidders to submit so that proposals can be evaluated against each other on a comparable basis, adding new bid requirements to improve operations and performance, or changes to the model PPA included in the bid solicitation to incorporate additional protections for SPS and its customers against performance risks that should be the responsibility of the power supplier. In this way, SPS s power purchase process and practices are continually being updated and improved to enhance effectiveness. Klein Direct Revenue Requirement Page RR - Page 0 of 0 0

16 IV. LONG-TERM PURCHASED POWER CONTRACTS 0 0 Q. Have you provided attachments that summarize the PPAs under which SPS incurred capacity-related costs during the Test Year and identify the related costs? A. Yes. Attachment JCK-RR- provides a summary of the long-term PPAs under which SPS incurred costs during the Test Year. Attachment JCK-RR- provides the capacity-related costs incurred during the Test Year under each of the contracts. SPS is seeking to recover costs associated with several PPAs. Included in the Test Year costs are known and measurable adjustments to reflect costs that will begin or end before the start of the Rate Year. All of the PPAs under which capacity-related costs were incurred in the Test Year were reviewed by the Commission in previous SPS rate cases and their capacity-related costs were approved by the Commission in SPS s last litigated rate case, Docket No.. Attachment JCK-RR- identifies the start and end dates of the thermal PPAs for which SPS is requesting recovery of some costs through base rates. Q. What costs associated with these contracts does SPS propose to include in base rates in this proceeding? A. Attachment JCK-RR- lists the various charges incurred under PPAs in the Test Year and identifies the charges for which SPS is seeking recovery through base rates. SPS proposes to include in its cost of service the Test Year capacity-related charges with pro forma adjustments. In general, the capacity-related charges are those for capacity or demand and non-fuel items, such as O&M expenses or Application of Southwestern Public Service Company for Authority to Change Rates, Docket No. (Dec., 0). Klein Direct Revenue Requirement Page RR - Page of 0 0

17 turbine start/scheduling charges. The Test Year capacity-related costs for all contracts totaled $0,0, (total company), before considering pro forma adjustments. Q. Has SPS recovered capacity-related costs as defined above through base rates previously? A. Yes. I am not a regulatory expert, but my understanding is that some capacity-related costs have been recovered through base rates for many years. Variable O&M charges and other non-fuel PPA charges were first included in SPS s base rates adopted in Docket No. based on the Unanimous 0 Stipulation entered into by parties in Docket No.. The continuation of this practice was proposed in Docket Nos., 0, 00, and. This practice is consistent with TAC.(a)(), which prohibits the recovery of demand or capacity costs in fuel costs absent special circumstances. In Docket No., the Commission approved the capacity-related PPA costs proposed under this practice, which SPS proposes to continue in this rate case.

18 0 0 V. REASONABLENESS OF SPS S CAPACITY-RELATED COSTS Q. Were the PPA capacity-related costs SPS incurred in the Test Year reasonable? A. Yes. These costs were incurred under contracts reviewed in previous base rate cases and fuel reconciliations. The Lea Power Partners, LLC ( LPP ) PPA and the PPAs with Oneta Power, LLC (formerly Calpine Energy Services, L.P.) ( Oneta ) were the results of competitive solicitations. The Borger Energy Associates, L.P. ( BEA ) contract was certificated by the Commission in. The capacity cost under the contract with the City of Lubbock (Cooke Facility) is $. per kilowatt per month, which is a reasonable cost based on Resource Planning analysis. Given SPS s need for capacity in 0-0, it was reasonable and necessary to make these capacity purchases to provide SPS s customers with reliable electric service. Q. Have you made pro forma adjustments for known and measurable changes? A. Yes. I have made several adjustments. The pro forma adjustments are identified for each contract in the Pro Forma Adjustments column of Attachment JCK-RR-. First, there is a contract with Golden Spread Electric Cooperative, Inc. that expired before the end of the Test Year. Thus, a pro forma adjustment was made equal to the Test Year capacity-related costs incurred under this contract to remove those costs. Please refer to Attachment JCK-RR-, lines -. Application of Southwestern Public Service Company for Certification of Qualifying Facility Purchased Power Contract Under Section.0 of PURA, Docket No. (Oct. 0, ). Klein Direct Revenue Requirement Page RR - Page of 0 00

19 Second, PPA contract provisions for BEA, Oneta I and II, City of 0 0 Lubbock, LPP, and Sid Richardson specify price terms for capacity-related costs and variable O&M expense that change from the Test Year to the Rate Year, or that allow for capacity testing to change the contracted capacity. The pro forma adjustments for these contracts account for these contract provisions. Please refer to Attachment JCK-RR-, lines -, -, 0-, -, -, and -, respectively. Third, the PPA contract provisions for the City of Lubbock specify capacity payment refunds to SPS when units are not operational. During the Test Year, SPS received capacity payment refunds due to the non-operational status of three units, which are reflected in the Test Year cost. However, two of the units are scheduled to return to service before the start of the Rate Year. Accordingly, SPS does not expect to receive the same level of refunds in the Rate Year. The pro forma adjustment accounts for the change in operational status of the two units that will be online during the entire Rate Year. No adjustment has been made to remove the refunds received in the Test Year for the MW unit that is expected to return to service in the last quarter of the Rate Year. Please refer to Attachment JCK-RR-, line. Fourth, the PPA for LPP includes an adjustment to the monthly energy tolling payment (a variable O&M payment) if the actual net heat rate for the facility is less than % of the PPA s predicted net heat rate (increases variable O&M), or greater than the predicted heat rate (reduces variable O&M). In June of SPS has two PPAs with Oneta: Oneta I runs from January, 0 through December, 0; Oneta II runs from June, 0 through May, 0. Klein Direct Revenue Requirement Page RR - Page of 0 0

20 0 0, the heat rate test result showed a heat rate less than % of the predicted net heat rate, resulting in an increase to the variable O&M charge. The facility s actual net heat rate has improved due to a permanent plant upgrade that improved the efficiency of the plant. Due to the upgrade at the plant, the improved heat rate is expected to continue for the foreseeable future. Accordingly, the pro forma adjustment accounts for this change, applying to the entire Rate Year the increase to the monthly energy tolling payment that was in effect starting in July of 0. Please refer to Attachment JCK-RR-, line. SPS witness Arthur P. Freitas has reflected these pro forma adjustments in the cost of service study he presents. Q. What is the net change due to all these pro forma adjustments? A. The net change is a $,,0 (total company) increase, which brings the total of adjusted Test Year capacity-related costs to $,, (total company). Q. Does this conclude your pre-filed direct testimony? A. Yes. Klein Direct Revenue Requirement Page 0 RR - Page of 0 0
