3 1 I. INTRODUCTION Q. PLEASE STATE YOUR NAME AND OCCUPATION. A. My name is Charles R. Burdick. I am Manager of Revenue Analysis in the Revenue Requirements North department for Xcel Energy Services Inc Q. HAVE YOU PREVIOUSLY PROVIDED TESTIMONY IN THIS PROCEEDING? A. Yes. I filed Direct Testimony on behalf of Northern States Power Company (Xcel Energy or the Company) presenting the Company s three-year multiyear rate plan (MYRP) proposal in this proceeding. I also filed Rebuttal Testimony supporting the Stipulation of Settlement (Settlement) entered into by the Company and eight other parties in this rate case (the Settling Parties), and responding to portions of the Direct Testimony of Office of the Attorney General (OAG) witness Mr. John Lindell. Q. WHAT IS THE PURPOSE OF YOUR SURREBUTTAL TESTIMONY? A. I provide information on compliance procedures under the Settlement including the capital and property tax true-ups and illustrative schedules quantifying the Settlement s impact for ratemaking. I also respond to assertions and correct portions of the information in OAG witness Mr. Lindell s Rebuttal Testimony comparing the results of the Company s prior rate cases to the Settlement revenue requirements II. SUPPORT FOR THE SETTLEMENT Q. WHAT COMPLIANCE STEPS WILL BE NECESSARY TO IMPLEMENT THE SETTLEMENT? 1 Burdick Surrebuttal

4 A. While the Settlement describes the Settling Parties agreement on revenue outcomes, it does not articulate all of the compliance procedures needed for implementation. These additional compliance steps are implementation of capital and property tax true-ups and development of illustrative schedules that quantify the Settlement s impact for ratemaking. I provide details on these matters below. Q. PLEASE DESCRIBE THE CAPITAL AND PROPERTY TAX TRUE-UPS THAT WILL BE IMPLEMENTED UNDER THE SETTLEMENT. A. As part of its ongoing compliance requirements, the Company will implement capital and property tax true-ups based on my Direct Testimony and modified for the Settlement as described in our response to Information Request MPUC-502 from Commission Staff. Our October 5, 2016 response provides details on the capital and property tax true-up compliance steps and is provided as Exhibit (CRB-3), Schedule 1. Q. PLEASE DESCRIBE THE ILLUSTRATIVE SCHEDULES MENTIONED ABOVE. A. Illustrative schedules are provided as Exhibit (CRB-3), Schedules 2 through 7. These provide the following information: Schedule 2 Summary Schedule Rate Base and Income Statement Bridge Schedule Schedule Rate Base and Income Statement Bridge Schedule Schedule Rate Base and Income Statement Bridge Schedule Schedule Rate Base and Income Statement Bridge Schedule Schedule 7 Summary of Revenue Requirements 2 Burdick Surrebuttal

5 Q. HOW IS THE RATE CASE REVENUE REQUIREMENT ADJUSTED TO ARRIVE AT THE SETTLEMENT RESULT? A. The illustrative schedules start with the Company s as-filed request for 2016, 2017, and 2018, plus the Company s forecast for The schedules then summarize the Department s recommended adjustments from their Direct Testimony. First, the schedules itemize adjustments that are due to legislative changes or Commission orders. These adjustments are quantified in the Direct Testimony of Department witness Ms. Nancy Campbell and Company witness Ms. Anne Heuer: Bonus Tax Remaining Life Study NSPM Service Company Allocations Next, the schedules show amortization of expenses matched to the four-year term of the Settlement. The amortizations expense the same totals as indicated in the Department s Direct Testimony, but over four years instead of five. These adjustments are quantified in the Direct Testimony of Department witnesses Mr. Dale Lusti and Ms. Campbell, and Company witness Ms. Heuer, with four-year detail provided in Exhibit (CRB-3), Schedule 8: 4-Year Amortization of rate case expenses Transco 2015 Amortization Then, the schedules provide two bulk adjustments to represent the balance of the Department s recommendations: Rate Base 3 Burdick Surrebuttal

6 Income Statement The schedules show a subtotal to tie to the Department s position in Direct Testimony. Q. PLEASE DESCRIBE THE RATE BASE ADJUSTMENT. A. The Rate Base adjustment ties to the total remaining rate base adjustments from the Department s Direct position. Q. PLEASE DESCRIBE THE INCOME STATEMENT ADJUSTMENT. A. The Income Statement adjustment represents the balance of the Department s adjustments. Rather than showing an adjustment to each expense category, the Income Statement adjustment provides a revenue offset to arrive at the same revenue deficiency in the Department s Direct Testimony. Q. WHAT ADJUSTMENTS ARE MADE SUBSEQUENT TO THE DEPARTMENT S POSITION? A. To illustrate the difference between the Department s position in Direct Testimony and the Settlement outcome, we show the following adjustments: CIP Commission Order CapX2020 Fargo and Brookings remain in the TCR Rider LED Street Lighting Settlement Rate Shape 2016 Sales True-Up Cash Working Capital Net Operating Loss 4 Burdick Surrebuttal

7 Q. DO THE CIP AND TCR-RELATED ADJUSTMENT NOTED ABOVE IMPACT BASE RATE REVENUE REQUIREMENTS? A. No. As discussed in Ms. Heuer s Direct Testimony, the CIP and TCR-related adjustments set the rate base, revenues, and expenses in the base rate cost of service to reflect that certain costs will be recovered in riders. We adjust costs and offsetting revenues simultaneously so that the net revenue requirement impact on base rates is near zero. Q. PLEASE DESCRIBE THE CIP COMMISSION ORDER ADJUSTMENT. A. As discussed in Ms. Heuer s Direct Testimony, this adjustment sets CIPrelated revenues and expenses to match the Commission s Order in Docket No. E,G002/CIP issued October 12, As noted above, this adjustment has no revenue requirement impact for base rates. Q. PLEASE DESCRIBE THE ADJUSTMENT FOR CAPX2020 FARGO AND BROOKINGS PROJECT TO REMAIN IN THE TCR RIDER. A. This adjustment removes the capital costs and offsetting revenues related to the CapX2020 Fargo and Brookings lines from the cost of service so that the projects will continue to be recovered in the TCR per the Settlement. This Settlement term and adjustment remove the need to shift recovery of these costs to base rates at the conclusion of the rate case as was originally proposed by the Company in Ms. Heuer s Direct Testimony. Please see Exhibit (CRB-3), Schedule 9 for supporting detail. Q. PLEASE DESCRIBE THE LED STREET LIGHTING ADJUSTMENT. 5 Burdick Surrebuttal

8 A. Pages 9-11 of the Settlement address the issue of LED Street Lighting and its proposed treatment. Exhibit (CRB-3), Schedule 10, attached, provides supporting detail that informed the Settlement. Q. PLEASE DESCRIBE THE SALES TRUE-UP ADJUSTMENT. A. This adjustment is a placeholder for implementing the 2016 sales true-up according to the compliance filing proposed for February of Q. PLEASE DESCRIBE THE SETTLEMENT RATE SHAPE ADJUSTMENT. A. This adjustment affects the settlement rate shape and ties to the overall revenue requirement outcome in the Settlement. Q. PLEASE DESCRIBE THE SECONDARY CALCULATION ADJUSTMENTS. A. s to Cash Working Capital and Net Operating Loss are secondary calculations that are quantified once all other adjustments are determined. As generally accomplished in a rate case, these adjustments are calculated in the cost of service to determine the final revenue requirement based on all other adjustments. Q. WILL SOME ADJUSTMENTS NEED TO BE RECALCULATED AFTER THE 2016 SALES TRUE-UP? A. Yes. The Cash Working Capital (CWC) and Net Operating Loss (NOL) secondary calculations will need to be updated. For example, if the 2016 Sales True-Up has lower sales worth $10 million in revenues, we would include an adjustment to reduce retail revenues by $10 million. This would increase the revenue requirement by $10 million before 6 Burdick Surrebuttal

9 secondary calculations, and secondary calculations would recalculate accordingly. The total revenue result would be $85 million ($75 million + $10 million), plus the impact of incremental CWC and NOL secondary calculations. Similarly, if the 2016 Sales True-Up has higher sales worth $10 million in revenues, we would include an adjustment to increase retail revenues by $10 million. This would decrease the revenue requirement by $10 million before secondary calculations, and secondary calculations would recalculate accordingly. The revenue result would be $65 million ($75 million - $10 million), plus the impact of incremental CWC and NOL secondary calculations. The two examples above describe what would be included in the final Settlement illustrative schedules for Q. DO THE ILLUSTRATIVE SCHEDULES MEAN THAT THE COMPANY AGREES WITH THE SPECIFIC ADJUSTMENTS REFLECTED IN THEM? A. No. These schedules are being presented to illustrate a way of viewing the revenue outcome of the Settlement, but they do not represent Parties positions on each issue. As discussed by Company witness Mr. Chandarana in his Rebuttal Testimony, the Settlement allows the Settling Parties to recognize their respective positions on issues along with an overall revenue outcome. Additionally, the illustrative schedules demonstrate that the Settlement revenues are consistent with past Commission orders. 7 Burdick Surrebuttal

10 Q. DO YOU PROVIDE ANY OTHER INFORMATION RELATED TO IMPLEMENTATION OF THE SETTLEMENT? A. Yes. Provided as Exhibit (CRB-3), Schedule 11 is our response to Information Request MPUC-13 related to use of existing riders during the term of the MYRP. Schedule 11 also includes our responses to Information Requests OAG and OAG-175, which are referenced in MPUC-13. Mr. Chandarana discusses the use of riders further in his Surrebuttal Testimony. III. RESPONSE TO OAG Q. WHAT IS THE PURPOSE OF THIS SECTION OF YOUR TESTIMONY? A. I respond to assertions of OAG witness Mr. Lindell based on his comparison of the Settlement revenue requirements to the results of the Company s prior rate cases. Q. WHAT ARE YOUR CONCERNS WITH MR. LINDELL S ASSERTIONS? A. First, Mr. Lindell s Tables 1 and 2 did not provide an accurate comparison of the Settlement revenue requirements to the Company s initial request in this case. In Table 1, Mr. Lindell presented the Company s initial three-year request compared to the four-year Settlement. Due to the different time periods represented, these amounts are not comparable. As a result, Mr. Lindell s Table 2 provides an incorrect percentage of the Settlement revenue requirement compared to the Company s initial request. Q. WHAT CORRECTIONS TO MR. LINDELL S TABLE 1 ARE NECESSARY? A. To provide an accurate comparison for the four-year MYRP term, Table 1 should reflect an amount that is this representative of what the Company s 8 Burdick Surrebuttal

11 three year MYRP plus a 2019 revenue increase based on the Company s forecasts presented in our initial filing. In other words, and as noted in Mr. Chandarana s Rebuttal Testimony and in my Rebuttal Testimony, an appropriate comparison of the four-year Settlement revenue requirement to our initial request would include the amounts in our initial three-year plan ( ) plus the Company s forecasted revenue requirement increase necessary for Table 1 below includes the forecasted amount for 2019 to ensure an accurate comparison of the Company s initial request to the four- year Settlement. Table 1 Incremental Revenue Requirements Q. GIVEN THE INFORMATION IN TABLE 1 ABOVE, HOW DOES THE SETTLEMENT REVENUE COMPARE TO THE COMPANY S INITIAL REQUEST. A. The Settlement revenue is approximately half of the Company s initial request (three-year plan + forecast). Mr. Lindell s calculation of 62 percent of the Company s initial request is not accurate Total Request/Forecast $195 $52 $50 $82* $380 Settlement $75 $60 $0 $50 $185 Cumulative Revenue Requirements Request/Forecast $195 $247 $297 $380* Settlement $75 $135 $135 $185 * Company forecast included in initial application. 9 Burdick Surrebuttal

12 Q. DO YOU HAVE OTHER CONCERNS WITH MR. LINDELL S COMPARISON OF THE COMMISSION-APPROVED AMOUNTS COMPARED TO THE COMPANY S REQUESTED AMOUNTS IN PRIOR RATE CASES? A. Yes. Looking only at percentages that compare Commission-approved amounts to requested amounts in the Company s prior rate cases is not particularly meaningful. These percentages do not consider any of the policy decisions, underlying context, operational objectives, or facts specific to those cases that were considered by the Commission during those proceedings. Rates are not set in a vacuum, nor are they based on how approved rates compare to a company s initial requests in past cases. Rather, the Commission makes rate case decisions based on the facts and record in a current case. IV. CONCLUSION Q. DOES THIS CONCLUDE YOUR REBUTTAL TESTIMONY? A. Yes, it does. 10 Burdick Surrebuttal

Is Xcel s annual capital projects true-up proposal included as part of the August 16, 2016 settlement? 2. If so, please provide the base line amount to be used for each of the four years, and, 3. Please explain if there are any changes in the true-up calculation methodology proposed by Xcel in its initial filing? Please file a copy of your response in the edocket system. Please forward a copy of your response to the Administrative Law Judge. Response: The Settlement describes the Settling Parties agreement on the revenue outcomes but does not articulate all of the compliance procedures needed for implementation. The Settling Parties recommend the following compliance steps to implement the Settlement: Capital True-Up The Company will implement the capital true-up set forth in Company witness Mr. Burdick s Direct Testimony on pages and on the timeline set forth on pages and Schedule 15, attached to this response. Given the Settlement, the base line amount to be used for each of the four years will be the total annual capital related 1

14 Northern States Power Company Exhibit (CRB-3), Schedule 1 Page 2 of 2 revenue requirements set forth in Department witness Mr. Lusti s second errata to Schedule DVL-9. Property Tax True-up The Company will implement the property tax true-up set forth in Mr. Burdick s Direct Testimony on pages and on the timeline set forth on pages and Schedule 15. Given the Settlement and the property tax deferral in 2016, there will be no true-up in 2016 and the Company will use the property tax expense amount for 2016 established by Department witness Mr. Lusti in his Direct Testimony as the baseline for the property tax true-up for 2017, 2018 and 2019 property tax expense.
