Southwestern Public Service Company Xcel Energy Operating Companies Joint Open Access Transmission Tariff Revisions to Wholesale Real Power Losses for Southwestern Public Service Company Docket No. ER19-____-000
Dear Secretary Bose:
Pursuant to Section 205 of the Federal Power Act (“FPA”),1 Part 35 of the regulations of the Federal Energy Regulatory Commission (“FERC” or “Commission”),2 and Order No. 714,3 Public Service Company of Colorado (“PSCo”),4 on behalf of Southwestern Public Service Company (“SPS”), hereby submits eTariff records revising Sections 15.7 and 28.5 of the Xcel Energy Operating Companies Open Access Transmission Tariff (“Xcel Energy Tariff” or “Tariff”).5 The revisions update the stated real power loss percentages (“loss factors”) for service on the SPS system so they (i) are based on the most recent study of SPS system losses, and (ii) are consistent with the loss factors approved for and reflected in SPS’s retail rates in Texas and New Mexico.
SPS respectfully requests that the Commission accept the proposed tariff revisions for filing effective April 1, 2019, sixty (60) days after filing, without suspension.

I. BACKGROUND
SPS is a New Mexico corporation and a wholly owned subsidiary of Xcel Energy Inc. (“Xcel Energy”). SPS is an operating utility engaged in, inter alia, the generation, purchase, transmission, distribution and sale of electricity to approximately 390,000 retail customers in portions of Texas and New Mexico. SPS also sells electric power and provides transmission service at wholesale to other utilities and electric cooperatives in Texas, New Mexico, Kansas, and Oklahoma.
SPS is a transmission-owning member of the Southwest Power Pool, Inc. (“SPP”), a FERC-approved Regional Transmission Organization (“RTO”). Transmission service over the SPS transmission system has been available under the SPP Open Access Transmission Tariff (“SPP Tariff”) since June 2000.
Xcel Energy Services Inc. (“XES”) is the centralized service company subsidiary of Xcel Energy and, as such, performs an array of administrative and general services on behalf of the Xcel Energy Operating Companies.6 Among other things, XES submits filings with and appears in proceedings before the Commission on behalf of SPS.
II. REASONS FOR THIS FILING
A. Updated Transmission and Distribution Loss Study.
The primary reason for this filing is to ensure that the transmission and distribution real power losses charged to SPS’s wholesale customers reflect the most recent analysis of the losses SPS experiences in providing such services and are consistent with the loss factors reflected in SPS’s retail rates in Texas and New Mexico. As discussed further by SPS Witness Mr. Wesley L. Berger, the existing Transmission and Distribution System – Primary Voltage real power loss factors set out in the Xcel Energy Tariff applicable to SPS were accepted effective May 1, 2016, Docket No. ER16-1030-000.7 The real power loss factors established in that docket were based on a loss study that analyzed data for the period from July 2012 through June 2013 (the “2013 Loss Study”).
The updated real power loss factors contained in this filing are based upon the most recent SPS loss study, completed in 2017 for the period of January 2016 through December 2016 (the “2016 Loss Study”). The 2016 Loss Study uses the same methodology as the 2013 Loss Study, with minor enhancements discussed by SPS Witness Mr. Duane J. Ripperger, and was accepted by the retail regulatory agencies with jurisdiction over SPS in 2018: the Public Utility Commission of Texas (“PUCT”) and the New Mexico Public Regulation Commission 6 The Xcel Energy Operating Companies are: SPS, PSCo, and Northern States Power Company, a Minnesota
corporation, and Northern States Power Company, a Wisconsin corporation (collectively, the “NSP Companies”). The instant filing does not affect the rates for transmission service on the PSCo or NSP Companies’ systems.

(“NMPRC”).8 SPS then began to prepare this filing to similarly update the loss factors used in calculating wholesale rates.
As discussed more fully by Mr. Ripperger, the 2016 Loss Study quantifies, through engineering analysis and calculations, the physical power and energy losses that occurred on the SPS transmission and distribution system during the study period. The 2016 Loss Study reflects the impacts of changes to the SPS system since the 2013 Loss Study, including initiation of the SPP Integrated Marketplace, installation of new 345 kV transmission facilities, and increased wind and solar generation, including generation connected to the SPS distribution system.9 Implementing the updated loss factors in the Xcel Energy Tariff will provide for consistent allocations of costs between the three SPS rate jurisdictions: FERC wholesale, Texas retail, and New Mexico retail.
B. Summary of Current and Proposed Real Power Loss Factors.
The real power demand and energy loss factors for service on the SPS transmission system (“Transmission Loss Factors”) are stated as percentage values in Sections 15.7 and 28.5 of the Xcel Energy Tariff and incorporated into Attachment M, Appendix 1 of the SPP Tariff. The real power demand and energy loss factors for service on the SPS distribution system (“Distribution Loss Factors”), applicable to those SPS wholesale customers taking service at primary distribution voltage, are also stated in Sections 15.7 and 28.5 of the Xcel Energy Tariff. As discussed by Mr. Berger, the transmission loss factors total two transmission level loss factors described in the 2016 Loss Study into a composite transmission loss factor for the Xcel Energy Tariff and the SPP Tariff.10
As noted, the currently effective Transmission Loss Factors and Distribution Loss Factors accepted in Docket No. ER16-1030-000 were based on the 2013 Loss Study.11 In this filing, SPS proposes to update the Transmission Loss Factors and Distribution Loss Factors with the values derived from the 2016 SPS Loss Study and accepted by the PUCT and NMPRC. The following table shows SPS’s currently effective and proposed loss demand and energy factors:

8.157751% 8.846390% 6.035731% 6.327826%
C. Impact of Proposed Tariff Revisions on Wholesale Customers.
The proposed updated Transmission and Distribution Loss Factors affect network transmission service customers in SPP Zone 11 who purchase transmission service under the SPP Tariff as well as wholesale production service customers who purchase power from SPS under wholesale requirements power sale agreements at the transmission and distribution level.12 The Tariff revisions will affect the calculations of billing demands for both network transmission service under the SPP Tariff and wholesale production services provided by SPS. Specifically, the updated loss factors affect these wholesale power supply services because the loss factors are included in the calculation of how much energy each wholesale customer is purchasing under its power supply agreement.13 Therefore, although this filing is not amending these power supply agreements, the updated real power loss factors will affect the calculation of charges pursuant to the power supply agreements’ existing terms.
Initially, SPS estimates the updated loss factors together will result in a net decrease in the overall annual costs to wholesale customers of approximately $230,700, or approximately 0.07 percent.14 The overall charges to network transmission service customers under the SPP Tariff in Zone 11 (the SPS zone) will be reduced due to the reduction in the transmission Demand Loss Factor. The impact of the revised real power loss factors on wholesale production customers is a small annual cost increase. Exhibit No. SPS-0003 calculates the estimated impact by SPS wholesale customer using the revised loss factors applied to 2018 billings.15
12 The affected wholesale transmission service customers in Zone 11 are: Golden Spread Electric
Cooperative, Inc. (for itself and Tri-County Electric Cooperative, Inc.); Farmers’ Electric Cooperative, Inc.; Lea County Electric Cooperative, Inc.; Central Valley Electric Cooperative, Inc.; Roosevelt County Electric Cooperative, Inc.; and West Texas Municipal Power Agency. All of these network transmission service customers also purchase power from SPS pursuant to Commission-approved cost-based wholesale requirements power supply sale agreements. Golden Spread purchases wholesale requirements power only for its Tri-County Electric Cooperative, Inc. member load.
13 For example, see the Replacement Power Sales Agreement between SPS and Central Valley Electric Cooperative dated January 15, 2010, SPS Electric Rate Schedule 114, Service Schedule A, Sections 3, 4, 5, and 6.
14 See Exhibit No. SPS-0003. 15 Berger Direct Testimony, Exhibit No. SPS-0001 at P. 14. The net impact to each wholesale customer is an
estimated cost reduction, with the exception of Central Valley Electric Cooperative, Inc. (“Central Valley”). Central Valley is estimated to see a small total cost increase – approximately $6800 compared to
Ms. Kimberly D. Bose January 30, 2019 Page 5
Notably, the proposed Tariff revisions will not affect the collection of energy losses for transmission services under the SPP Tariff. Under Section II.(b) of Attachment M to the SPP OATT, energy losses are determined by the SPP regional system dispatch and included in the locational marginal prices charged to market participants, including SPS and network customers on the SPS system. The revised Energy loss factors affect only the allocation of SPS system energy costs between SPS wholesale production and retail customers.
D. Stakeholder Communications
In addition to being stated in the Xcel Energy Tariff, the SPS Transmission Demand loss factor is included in Attachment M (Loss Compensation Procedure), Appendix 1, to the SPP Tariff. SPS will work with SPP to file to modify Attachment M, Appendix 1 to the SPP Tariff to reflect the updated SPS transmission demand loss factors for purposes of calculating monthly billing determinants for the wholesale loads taking network service in the SPS rate zone (Zone 11).16 SPS discussed the need for this revision to Attachment M, Appendix 1 with SPP, and SPP has indicated it expects to submit companion changes to the SPP Tariff shortly after SPS submits this filing, to be effective on the same effective date approved by the Commission in this proceeding.
Prior to submitting this filing, on January 18, 2019, SPS also provided information to its wholesale transmission and production customers to notify them of the proposed changes to the SPS real power losses factors and the anticipated financial impact to each affected wholesale customer, and offered to hold individual meetings with each wholesale customer.17
E. The Tariff Revisions Should be Accepted for Filing
For the reasons stated above, SPS requests that the Commission accept the proposed changes to Sections 15.7 and 28.5 of the Xcel Energy Tariff for filing, to be subsequently incorporated into Attachment M, Appendix 1 of the SPP Tariff. The proposed revisions are further explained in the attached Testimonies and Exhibits of Mr. Wesley L. Berger and Mr. Duane J. Ripperger in support of the instant filing, including the 2016 Loss Study included as Exhibit No. SPS-0005 to Mr. Ripperger’s testimony. As noted, the 2016 Loss Study uses the same basic methodology used in the 2013 Loss Study supporting SPS’s currently effective real power loss factors in Sections 15.7 and 28.5, with certain refinements discussed by Mr. Ripperger.
total transmission service and production service billings of $29.97 million – because of the high load factor at which Central Valley purchases energy from SPS. Id. at P. 15.
16 Berger Direct Testimony, Exhibit SPS-0001 at P. 6. Attachment M, Appendix 1 refers to a Delivery Loss Factor (“DLF”) and an Injection Loss Factor (“ILF”). The ILF equals the SPS Demand Loss factor stated in Section 15.7 and 28.5. The DLF is calculated as 1/(1-ILF)-1. So an SPS transmission demand real power loss factor (ILF) of 2.738606% would result in an SPP DLF of 2.8115717%. Id. at PP. 12-13.

III. ADDITIONAL INFORMATION SUBMITTED IN SUPPORT OF FILING
A. Information Required by Section 35.13 of the Commission’s Regulations, 18 C.F.R. § 35.13
1. Contents of Filing – Section 35.13(b)(1)
In addition to this transmittal letter, the filing consists of the following:
• Electronic marked and clean versions of Sections 15 and 28 of the Xcel Energy Tariff in eTariff format, including the revisions to Section 15.7 and 28.5;
• the testimony, exhibits and affidavit of Mr. Wesley L. Berger (Exhibit Nos. SPS-0001, SPS-0002, and SPS-0003); and
• the testimony, exhibit and affidavit of Mr. Duane J. Ripperger (Exhibit Nos. SPS-0004 and SPS-0005), including the 2016 Loss Study.
B. Requested Effective Date – Section 35.13(b)(2)
SPS respectfully requests that the Commission allow the proposed revised Tariff revisions to be effective April 1, 2019, sixty (60) days after filing, without suspension or condition for good cause shown. As noted, the transmission Demand Loss change will result in a small reduction in fixed charges to network transmission service customers (due to lower billing determinants after adjusting for transmission demand losses), and overall the proposed loss factors result in a net cost decrease to SPS wholesale customers of approximately $230,700 annually.18 The revised real power loss factors reflect the most current SPS system loss study available, and will provide for consistent cost allocations between the three SPS rate jurisdictions (FERC wholesale, Texas retail and New Mexico retail).
If the Commission nonetheless believes a suspension is warranted, SPS respectfully asks that the Commission allow the proposed revised tariff provisions to become effective April 1, 2019, subject to refund, after only a nominal suspension. In West Texas Utilities Co., the Commission explained that a minimal suspension period is justified in cases where no more than ten percent of the proposed increase appears to be excessive.19 The overall rate change proposed here is negligible (-0.072 percent), and no portion of the minimal change in charges is excessive.
SPS believes the materials submitted herewith comply with the Commission’s filing requirements and will permit the Commission to review the proposed revisions and determine them to be just and reasonable. SPS respectfully requests waiver of any applicable filing or notice requirements under the Commission's Rules and Regulations as may be necessary to accept the proposed revisions to the Xcel Energy Tariff on the date requested.

Part III, Section 28 Nature of Network Integration Transmission Service
Version 0.3.0 Proposed Effective Date: 4/1/2019 Page 1 of 2 28 Nature of Network Integration Transmission Service
28.1 Scope of Service: Network Integration Transmission Service is a transmission
service that allows Network Customers to efficiently and economically utilize their Network Resources (as well as other non-designated generation resources) to serve their Network Load located in the Transmission Provider's Control Area and any additional load that may be designated pursuant to Section 31.3 of the Tariff. The Network Customer taking Network Integration Transmission Service must obtain or provide Ancillary Services pursuant to Section 3.
28.2 Transmission Provider Responsibilities: The Transmission Provider will
plan, construct, operate and maintain its Transmission System in accordance with Good Utility Practice and its planning obligations in Attachment R in order to provide the Network Customer with Network Integration Transmission Service over the Transmission Provider's Transmission System. The Transmission Provider, on behalf of its Native Load Customers, shall be required to designate resources and loads in the same manner as any Network Customer under Part III of this Tariff. This information must be consistent with the information used by the Transmission Provider to calculate available transfer capability. The Transmission Provider shall include the Network Customer's Network Load in its Transmission System planning and shall, consistent with Good Utility Practice and Attachment R, endeavor to construct and place into service sufficient transfer capability to deliver the Network Customer's Network Resources to serve its Network Load on a basis comparable to the Transmission Provider's delivery of its own generating and purchased resources to its Native Load Customers.
28.3 Network Integration Transmission Service: The Transmission Provider will
provide firm transmission service over its Transmission System to the Network Customer for the delivery of capacity and energy from its designated Network Resources to service its Network Loads on a basis that is comparable to the Transmission Provider's use of the Transmission System to reliably serve its Native Load Customers.
28.4 Secondary Service: The Network Customer may use the Transmission
Provider's Transmission System to deliver energy to its Network Loads from resources that have not been designated as Network Resources. Such energy shall be transmitted, on an as-available basis, at no additional charge. Secondary service shall not require the filing of an Application for Network Integration Transmission Service under the Tariff. However, all other requirements of Part III of the Tariff (except for transmission rates) shall apply to secondary service. Deliveries from resources other than Network Resources will have a higher priority than any Non-Firm Point-To-Point Transmission Service under Part II of the Tariff.
28.5 Real Power Losses: Real Power Losses are associated with all transmission
service. The Transmission Provider is not obligated to provide Real Power

The loss factors for Direct Assignment Facilities shall be determined on a case by case basis.
28.6 Restrictions on Use of Service: The Network Customer shall not use
Network Integration Transmission Service for (i) sales of capacity and energy to non-designated loads, or (ii) direct or indirect provision of transmission service by the Network Customer to third parties. All Network Customers taking Network Integration Transmission Service shall use Point-To-Point Transmission Service under Part II of the Tariff for any Third-Party Sale which requires use of the Transmission Provider's Transmission System. The Transmission Provider shall specify any appropriate charges and penalties and all related terms and conditions applicable in the event that a Network Customer uses Network Integration Transmission Service or secondary service pursuant to Section 28.4 to facilitate a wholesale sale that does not serve a Network Load.

Part III, Section 28 Nature of Network Integration Transmission Service
Version 0.3.0 Page 1 of 2 Proposed Effective Date: 4/1/2019 Approved Effective Date: 28 Nature of Network Integration Transmission Service
28.1 Scope of Service: Network Integration Transmission Service is a transmission
service that allows Network Customers to efficiently and economically utilize their Network Resources (as well as other non-designated generation resources) to serve their Network Load located in the Transmission Provider's Control Area and any additional load that may be designated pursuant to Section 31.3 of the Tariff. The Network Customer taking Network Integration Transmission Service must obtain or provide Ancillary Services pursuant to Section 3.
28.2 Transmission Provider Responsibilities: The Transmission Provider will
plan, construct, operate and maintain its Transmission System in accordance with Good Utility Practice and its planning obligations in Attachment R in order to provide the Network Customer with Network Integration Transmission Service over the Transmission Provider's Transmission System. The Transmission Provider, on behalf of its Native Load Customers, shall be required to designate resources and loads in the same manner as any Network Customer under Part III of this Tariff. This information must be consistent with the information used by the Transmission Provider to calculate available transfer capability. The Transmission Provider shall include the Network Customer's Network Load in its Transmission System planning and shall, consistent with Good Utility Practice and Attachment R, endeavor to construct and place into service sufficient transfer capability to deliver the Network Customer's Network Resources to serve its Network Load on a basis comparable to the Transmission Provider's delivery of its own generating and purchased resources to its Native Load Customers.
28.3 Network Integration Transmission Service: The Transmission Provider will
provide firm transmission service over its Transmission System to the Network Customer for the delivery of capacity and energy from its designated Network Resources to service its Network Loads on a basis that is comparable to the Transmission Provider's use of the Transmission System to reliably serve its Native Load Customers.
28.4 Secondary Service: The Network Customer may use the Transmission
Provider's Transmission System to deliver energy to its Network Loads from resources that have not been designated as Network Resources. Such energy shall be transmitted, on an as-available basis, at no additional charge. Secondary service shall not require the filing of an Application for Network Integration Transmission Service under the Tariff. However, all other requirements of Part III of the Tariff (except for transmission rates) shall apply to secondary service. Deliveries from resources other than Network Resources will have a higher priority than any Non-Firm Point-To-Point Transmission Service under Part II of the Tariff.
28.5 Real Power Losses: Real Power Losses are associated with all transmission
service. The Transmission Provider is not obligated to provide Real Power

III. OVERVIEW OF SPS’S FILING
A. Overview of SPS
Q. PLEASE DESCRIBE SPS. 1
A. Headquartered in Amarillo, Texas, SPS is a vertically integrated generation, transmission, 2
and distribution electric utility that serves approximately 390,000 retail and wholesale 3
customers in a 52,000 square-mile area of the Panhandle and the South Plains of Texas, 4
and eastern and southern New Mexico. SPS’s service area extends approximately 400 5
miles from north to south and 200 miles from east to west. SPS also owns certain 6
transmission facilities in Kansas and Oklahoma. SPS provides regulated, cost-based 7
retail services subject to the jurisdiction of the PUCT and the NMPRC. SPS also 8
provides cost-based requirements wholesale service to cooperative and municipal power 9
customers, with rates determined under production formula rate templates that are part of 10
the individual wholesale power sales agreements. 11
SPS is a member of the SPP regional transmission organization (“RTO”) and is 12
synchronously connected to the Eastern Interconnection grid. With limited exceptions, 13
all transmission services on the SPS system are provided under the SPP Tariff. SPS is 14
also connected to the Western Interconnection grid through three high-voltage direct-15
current back-to-back converters. Although SPS operates adjacent to the Electric 16
Reliability Council of Texas (“ERCOT”) grid, it has no direct interconnections with 17
ERCOT transmission owners. 18
Q. PLEASE DESCRIBE SPS’S SERVICE AREA. 19
A. The Texas retail jurisdiction is SPS’s single largest regulatory jurisdiction. SPS also 20
serves retail customers in a large portion of eastern and southeastern New Mexico. SPS’s 21
Exhibit No. SPS-0001 Page 6 of 16
service territory in both Texas and New Mexico is primarily agricultural, with large areas 1
of oil and natural gas production. Additionally, wholesale power sales and transmission 2
services have historically been a significant business segment for SPS. SPS directly 3
serves six wholesale requirements power sales (production) customers, who in turn may 4
serve member customers, and provides wholesale Network Integration Transmission 5
Service (“NITS”) to various customers with loads on the SPS transmission system. The 6
SPS transmission system is included in Zone 11 of the SPP Tariff. In total, wholesale 7
production services currently account for approximately 22 percent of SPS’s total 8
production demand, and wholesale transmission services currently account for 9
approximately 36 percent of SPS’s total transmission network demand. 10
B. SPS’s Filing and the Associated Testimony
Q. PLEASE SUMMARIZE THE CHANGES TO THE XCEL ENERGY TARIFF SPS 11
PROPOSES IN THIS FILING. 12
A. SPS proposes to update its transmission and distribution real power loss factors stated in 13
Sections 15.7 and 28.5 of the Xcel Energy Tariff. Under the Xcel Energy Tariff and the 14
SPP Tariff, customers are responsible for replacing the real power losses associated with 15
transmission service. SPS has conducted a loss study to determine the amount of real 16
power losses on its system and, based on this analysis, has updated the real power loss 17
percentages for its transmission system and its distribution-primary voltage system. 18
Because transmission service over the SPS system is primarily provided under the SPP 19
Tariff, SPP will separately make a filing to update the SPS loss factors in Attachment M, 20
Appendix 1 of the SPP Tariff, to conform to the updated SPS loss factors in the Xcel 21
Exhibit No. SPS-0001 Page 7 of 16
Energy Tariff, to be effective on the same effective date approved by the Commission in 1
this proceeding. 2
Q. WHY IS SPS SEEKING TO UPDATE ITS TRANSMISSION AND 3
DISTRIBUTION PRIMARY REAL POWER LOSS FACTORS? 4
A. The current transmission and distribution primary real power loss factors do not 5
accurately reflect the most recent study of the transmission and distribution losses SPS 6
experiences in providing service to its customers, including wholesale customers. SPS’s 7
current transmission and distribution loss factors stated in the Xcel Energy Tariff were 8
accepted in Docket No. ER16-1030-000, using a loss study that included data from July 9
2012 through June 2013 (the “2013 Loss Study”). In 2017, SPS completed an updated 10
loss study based on data from January 2016 through December 2016 (the “2016 Loss 11
Study”) and calculated new loss factors. The new loss factors were then filed with the 12
PUCT and the NMPRC. The updated loss factors were accepted by the NMPRC in its 13
final order in NMPRC Case No. 17-00255-UT, issued on September 5, 2018, and 14
accepted by the PUCT in its final order in PUCT Docket No. 47527, issued on December 15
10, 2018. SPS proposes to use the 2016 Loss Study as the basis for the updated real 16
power loss factors stated in the Xcel Energy Tariff applicable to SPS to ensure 17
comparability and consistency among all three jurisdictions (New Mexico, Texas, and 18
FERC). 19
Q. WHY DOES SPS NEED TO FILE DISTRIBUTION LOSS FACTORS WITH THE 20
COMMISSION? 21
A. SPS has transmission and wholesale production service customers who have delivery 22
points at primary distribution voltage. These real power demand and energy loss factors 23
Exhibit No. SPS-0001 Page 8 of 16
need to be updated so that they are consistent with the primary distribution loss factors 1
applied to SPS’s retail customers. 2
Q. HOW DO THE PROPOSED LOSS FACTORS COMPARE TO THE CURRENT 3
LINE LOSS FACTORS? 4
A. The proposed transmission loss factor for demand is slightly lower than the current 5
transmission demand loss factor, while the proposed transmission loss factor for energy is 6
slightly higher than the current transmission energy loss factor. SPS’s proposed primary 7
distribution loss factors are higher than the current distribution loss factors. A 8
comparison of the current and proposed loss factors is shown in Table 1: 9

Distribution - 8.157751% 8.846390% 6.035731% 6.327826% Primary Voltage
Q. WHAT IS THE PROPOSED EFFECTIVE DATE FOR THE REVISED LOSS 11
FACTORS? 12
A. SPS is requesting an effective date of April 1, 2019 for the revisions to Sections 15.7 and 13
28.5 of the Xcel Energy Tariff to reflect new demand and energy loss factors. 14
Q. PLEASE INTRODUCE THE OTHER WITNESS PROVIDING TESTIMONY IN 15
SUPPORT OF SPS’S PROPOSED LOSS FACTORS. 16
A. SPS’s filing is also supported by the Direct Testimony of Mr. Duane J. Ripperger, 17
Manager, Regional Transmission Initiatives for XES, Exhibit Nos. SPS-0004 and SPS-18
0005 (the “Ripperger Testimony”). 19
Exhibit No. SPS-0001 Page 9 of 16
Q. WHAT DOES MR. RIPPERGER ADDRESS IN HIS TESTIMONY? 1
A. Mr. Ripperger discusses how a system loss study is performed, and the methodology used 2
by SPS for the 2016 Loss Study. Mr. Ripperger also discusses certain refinements to the 3
2016 Loss Study as compared to the 2013 Loss Study. 4
Q. HAVE YOU QUANTIFIED THE IMPACT OF THE CHANGE PROPOSED IN 5
THE REVISED TEMPLATE ON SPS’S WHOLESALE DISTRIBUTION 6
SERVICE CUSTOMERS? 7
A. Yes. In Exhibit No. SPS-0003, I present the annual customer impact of the new loss 8
factors. In Section V of my testimony, I discuss my calculations of the annual customer 9
impact presented in Exhibit No. SPS-0003. 10
IV. CALCULATION OF PROPOSED LOSS FACTORS
Q. WHAT IS THE BASIS FOR THE REAL POWER LOSS FACTORS SPS 11
PROPOSES IN THIS PROCEEDING? 12
A. SPS is using the 2016 Loss Study, its most recent system loss study, as presented by Mr. 13
Ripperger. As I mentioned, the loss factors resulting from this study have been accepted 14
by the PUCT and the NMPRC. 15
Q. WHAT MODIFICATIONS DID YOU MAKE TO THE 2016 LOSS STUDY 16
RESULTS TO DERIVE THE PROPOSED WHOLESALE LOSS FACTORS? 17
A. The primary distribution loss factors proposed by SPS come directly from Appendices O 18
and P to the 2016 Loss Study (attached as Exhibit No. SPS-0005 to Mr. Ripperger’s 19
testimony). 20
I also used the loss factors from the 2016 Loss Study as the basis for SPS’s 21
proposed transmission loss factors, but modified the loss factors to tailor them to 22
Exhibit No. SPS-0001 Page 10 of 16
wholesale service. Specifically, I began with the Energy and Demand loss factors shown 1
in Appendices O and P to the 2016 Loss Study, and made one modification: I combined 2
the two transmission level loss factors described in the 2016 Loss Study into the 3
composite transmission loss factor for the Xcel Energy Tariff and the SPP Tariff. 4
Q. PLEASE DESCRIBE YOUR MODIFICATION IN ORDER TO CREATE A 5
COMPOSITE CALCULATION. 6
A. Both the Xcel Energy Tariff and the SPP Tariff employ a single loss factor for all 7
transmission voltage facilities. The 2016 Loss Study, however, contains two 8
transmission loss factors. Specifically, the 2016 Loss Study calculates a loss factor for 9
transmission facilities with a voltage of 115 kV or higher and a separate loss factor for 10
transmission facilities at a voltage level of 69 kV. Therefore, it was necessary for me to 11
calculate a composite transmission loss factor applicable to all transmission voltages to 12
be set out in the Xcel Energy Tariff and SPP Tariff. The current SPS transmission loss 13
factors accepted in Docket No. ER16-1030-000 were also calculated as composite 14
factors. 15
The modification I made to the Appendix O and P loss factor calculations was to 16
sum the losses for the two transmission service levels (levels 2 and 3) into a single total 17
transmission losses number. The total is shown on line 21 in the kW Loss by Level 18
column (column E) on page 1 and on line 21 in the kWh Loss by Level column (column 19
E) on page 2 of Exhibit No. SPS-0002. The remaining mathematical calculations on line 20
21 on both pages are identical to the original loss factor calculations done by Mr. 21
Ripperger and accepted by the PUCT and NMPRC. 22
Exhibit No. SPS-0001 Page 11 of 16
Q. IS IT NECESSARY TO MAKE A MODIFICATION TO THE 2016 LOSS STUDY 1
TO REMOVE GENERATOR STEP-UP TRANSFORMER LOSSES? 2
A. No. As discussed in the 2016 Loss Study, SPS metered its generators at the high side of 3
the generator step-up transformers during the time period of the 2016 Loss Study. 4
Q. WHAT ARE SPS’ PROPOSED LOSS FACTORS AFTER THESE 5
CALCULATIONS? 6
A. SPS proposes a transmission demand loss factor of 2.738606%, as shown on page 1, line 7
21 (column C) of Exhibit No. SPS-0002, and a transmission energy loss factor of 8
3.203203%, as shown on page 2, line 21 (column C) of Exhibit No. SPS-0002. SPS 9
proposes a distribution demand loss factor of 8.846390%, as shown on page 1, line 25 10
(column C) of Exhibit No. SPS-0002, and a distribution energy loss factor of 6.327826%, 11
as shown on page 2, line 25 (column C) of Exhibit No. SPS-0002. Table 1, on page 8 12
above, compares the currently effective wholesale transmission and distribution loss 13
factors with the proposed factors. 14
V. APPLICATION OF REAL POWER LOSS FACTORS TO CALCULATE 15 RATES APPLICABLE TO WHOLESALE SERVICES 16
Q. WHAT CUSTOMERS ARE AFFECTED BY SPS’S PROPOSED CHANGE TO 17
ITS LOSS FACTORS? 18
A. The network transmission service customers that purchase transmission service under the 19
SPP Tariff for loads on the SPS system (SPP Zone 11), and production service customers 20
who purchase power from SPS under wholesale requirements power sale agreements, are 21
both affected by SPS’s proposal to update its real power loss values. The demand loss 22
change will affect the calculation of billing demands for both network and production 23
customers, and the energy loss change will affect charges to production customers. 24
Exhibit No. SPS-0001 Page 12 of 16
Q. HOW DOES SPS APPLY THE LOSS FACTORS TO DETERMINE THE 1
CHARGES APPLICABLE TO NETWORK TRANSMISSION CUSTOMERS? 2
A. The loss factors developed by Mr. Ripperger in the 2016 Loss Study are what are termed 3
injection loss factors. However, these loss factors are typically applied to metered usage 4
values of network transmission customers in calculating monthly network demands. 5
Therefore, it is necessary to use what are termed delivery loss factors. Mr. Ripperger 6
explains how the delivery loss factors in the 2016 Loss Study are calculated. 7
As shown on page 1, line 21 (column B) of Exhibit No. SPS-0002, the 8
transmission demand delivery loss factor to be applied to metered usage is 1.028157. 9
The metered usage is multiplied by the delivery loss factor to determine the monthly 10
network demand. For example, if a customer has a metered demand of 600,000 kW, the 11
monthly network demand for billing purposes is 600,000 *1.028157 = 616,894 kW. 12
Similar delivery loss factors are shown in Exhibit No. SPS-0002 for the transmission 13
energy, distribution demand, and distribution energy loss factors. 14
Alternatively, a delivery loss factor can be expressed as a percentage as is done in 15
Attachment M, Appendix 1 to the SPP Tariff. This is calculated by the following 16
equation: delivery loss factor = [(1/(1 – injection loss factor)) - 1] * 100. Using the 17
transmission demand injection loss factor in Exhibit No. SPS-0002 on page 1, line 21 18
(column C) of 2.738606%, we can calculate the delivery loss factor SPP will show in 19
Attachment M as [(1/(1-.02738606)) - 1] * 100 = 2.815717%. The metered usage is 20
added to the product of the metered usage and the delivery loss factor expressed as a 21
percentage to determine monthly network demand. For example, if a customer has a 22
Exhibit No. SPS-0001 Page 13 of 16
metered demand of 600,000 kW, the monthly network demand for billing purposes is 1
600,000 + (600,000 * 2.815717%) = 616,894 kW. 2
Note that although the arithmetic calculations are performed differently, both 3
methodologies result in the same billing demand. 4
Q. HOW DOES SPS APPLY THE LOSS FACTORS TO DETERMINE THE 5
CHANGES APPLICABLE TO WHOLESALE PRODUCTION REQUIREMENTS 6
SERVICE CUSTOMERS? 7
A. SPS applies the delivery loss factors calculated using the first method described above to 8
the wholesale customers’ metered monthly usage. For example, if a wholesale customer 9
has a monthly demand of 100,000 kW and monthly energy usage of 50,000,000 kWh, 10
SPS would calculate the monthly billing determinants using the delivery loss factors 11
shown in line 21, Column B of pages 1 and 2 of SPS Exhibit 2. Specifically, billing 12
demand equals 100,000 * 1.028157 = 102,816 kW and billing energy equals 50,000,000 13
* 1.033092 = 51,654,600 kWh. 14
Q. WILL THE PROPOSED LOSS FACTOR CHANGES AFFECT ENERGY 15
LOSSES BILLED TO NETWORK CUSTOMERS UNDER THE SPP TARIFF? 16
A. No. Under Attachment M to the SPP OATT, energy losses are determined by the SPP 17
regional system dispatch and included in the locational marginal prices charged in the 18
SPP Integrated Marketplace to market participants, including network transmission 19
customers on the SPS system. The SPS Tariff loss factors do not affect these 20
calculations. 21
Exhibit No. SPS-0001 Page 14 of 16
Q. IS IT NECESSARY TO UPDATE ANY SPS WHOLESALE PRODUCTION 1
SERVICE AGREEMENTS TO REFLECT THE REVISED LOSS FACTORS? 2
A. No. The SPS production service agreements refer to the loss values as stated in the 3
applicable Tariff. As such, while the revised loss values will affect the calculation of 4
bills for SPS’s production customers, Commission acceptance of the revised real power 5
loss factors will not require revisions to the underlying agreements. 6
VI. COST IMPACT OF THE PROPOSED LOSS FACTORS
Q. HAVE YOU ESTIMATED THE COST IMPACT TO WHOLESALE 7
CUSTOMERS OF THE PROPOSED TARIFF CHANGES? 8
A. Yes. I estimated the cost impact to individual network transmission service customers 9
and wholesale requirements customers on the SPS system by recalculating SPS bills to 10
wholesale customers for calendar year 2018 using the proposed loss factors in place of 11
the currently effective loss factors. 12
Q. WHAT IS THE ESTIMATED COST IMPACT OF THE PROPOSED TARIFF 13
CHANGES TO SPS’S NETWORK TRANSMISSION SERVICE AND 14
WHOLESALE REQUIREMENTS CUSTOMERS? 15
A. The overall cost impact to these customers of the changes to the current loss factors is 16
estimated to be a decrease of $230,728 annually or approximately -0.072%. Exhibit No. 17
SPS-0003 shows the estimated transmission bill impact, production bill impact and net 18
impact for each wholesale customer. As noted, this estimate reflects billing data for the 19
twelve months from January 2018 through December 2018 and compares the amounts 20
billed using the current loss factors to the amounts that would have been billed had the 21
proposed loss factors been in effect. 22
Exhibit No. SPS-0001 Page 15 of 16
Exhibit No. SPS-0003 shows that charges to network transmission service 1
customers would be reduced as a result of the lower demand loss factor by approximately 2
$419,000 per year, while charges to wholesale production customers would increase by 3
approximately $188,000 per year. With one exception, all of SPS’s wholesale customers 4
are expected to see a slight net reduction. Central Valley Electric Cooperative is 5
estimated to see a slight increase ($6,833) because Central Valley Electric Cooperative 6
has a relatively high load factor and the energy loss factor is increasing. 7
Q. HAS SPS CALCULATED THE COST IMPACT TO POINT-TO-POINT 8
TRANSMISSION SERVICE CUSTOMERS? 9
A. No. Point-to-point service is provided only by SPP under the SPP Tariff. SPS does not 10
have the information necessary to calculate the impact of the slight reduction of the 11
transmission demand loss factor on SPP point-to-point transmission service customers. 12
Further, similar to network transmission customers, point-to-point customers’ energy 13
charges will not be impacted by this change to the SPS transmission energy loss factor 14
because energy losses are determined by the SPP regional system dispatch and included 15
in the locational marginal prices charged in the SPP Integrated Marketplace. 16
Q. DID SPS SHARE THE PROPOSED LOSS FACTOR CHANGES AND THE 17
ESTIMATED COST IMPACT WITH ITS WHOLESALE CUSTOMERS PRIOR 18
TO SUBMITTING THIS FILING? 19
A. Yes. SPS provided the proposed loss factors and the estimated cost impact analysis to 20
each of its wholesale customers on January 18, 2019, and offered to hold pre-filing 21
conference calls with each of the customers to explain the calculations and why SPS was 22
Exhibit No. SPS-0001 Page 16 of 16
making this filing. SPS answered a few questions, but none of the customers requested a 1
pre-filing meeting. 2
VII. CONCLUSION
Q. PLEASE SUMMARIZE YOUR RECOMMENDATIONS. 3
A. I recommend that the Commission approve SPS’s proposed revisions to Sections 15.7 4
and 28.5 of the Xcel Energy Tariff to incorporate the new SPS loss factors discussed in 5
my testimony, effective on April 1, 2019. The Tariff changes are just and reasonable 6
because they incorporate information from SPS’s most recent system loss study, and that 7
same loss study has recently been approved by the NMPRC and PUCT for retail 8
ratemaking purposes. 9
Q. DOES THIS CONCLUDE YOUR PRE-FILED DIRECT TESTIMONY? 10
A. Yes. 11

II. PURPOSE OF TESTIMONY 1
Q. WHAT IS THE SCOPE OF YOUR DIRECT TESTIMONY? 2
A. I will discuss the results of SPS’s 2016 Transmission and Distribution System Loss 3
Evaluation Study (the “2016 Loss Study”) conducted for the period from January 1, 4
2016 through December 31, 2016 (“Study Period”) and completed in July 2017. The 5
2016 Loss Study is the basis for the updated wholesale loss factors proposed by SPS in 6
this proceeding. Exhibit No. SPS-0005 is a copy of the 2016 Loss Study, which consists 7
of a narrative explanation of the study results and numerous detailed work papers. 8
Q. WAS YOUR DIRECT TESTIMONY PREPARED BY YOU OR UNDER YOUR 9
DIRECT SUPERVISION? 10
A. Yes. 11
III. SPS’S 2016 LOSS STUDY 12
Q. WHAT IS A LOSS STUDY? 13
A. A loss study is an engineering evaluation of the transmission and distribution (“T&D”) 14
losses incurred on an electrical system for a specified period of time. The goal of such a 15
study is to determine where the losses have occurred, that is, on what T&D elements 16
(transmission lines and transformers, distribution lines and transformers, and Generator 17
Step Up transformers) the losses occur and to then properly allocate the losses to each 18
individual type of element of the system. The losses determined in an engineering 19
evaluation should reasonably match losses derived from accounting records comparing 20
energy deliveries and energy supplies into the T&D system. After the losses have been 21
determined, loss factors representing the T&D losses on specific voltage levels of the 22
system are developed for rate making purposes. 23
Exhibit No. SPS-0004 Page 4 of 18
Q. WHY DID SPS PREPARE THE 2016 LOSS STUDY? 1
A. The previous SPS loss study had been completed utilizing data from July 1, 2012 through 2
June 30, 2013 (“2013 Loss Study”), and loss factors based on this study were 3
incorporated in the Xcel Energy Open Access Transmission Tariff (“Xcel Energy Tariff”) 4
in Docket No. ER16-1030-000 effective May 1, 2016. The SPS system has experienced 5
several significant changes since 2013, including implementation of the SPP Integrated 6
Marketplace, installation of new 345 kV transmission facilities by SPS, and increased 7
wind and solar generation. SPS concluded it would be appropriate to perform a new Loss 8
Study. Additionally, SPS committed to perform a new loss study that would cover a 9
study period ending no later than December 31, 2016 in both NMPRC Case No. 14-10
00348-UT and in the Non-Unanimous Stipulation in PUCT Docket No. 42004. 11
Q. HOW DOES THE 2016 LOSS STUDY COMPARE TO THE 2013 LOSS STUDY? 12
A. During the Study Period, energy supplies (i.e., “Resources”) and energy deliveries 13
(“Sales”)1 were lower in absolute terms than in the 2013 Loss Study. As a percentage of 14
SPS’s total Resources, however, actual losses in the 2016 Loss Study were slightly higher 15
than in the 2013 Loss Study. The losses calculated in the 2016 Loss Study are 1,948,829 16
megawatt hours (“MWh”), which is only 1.79% more than the actual losses of 1,914,545 17
MWh, i.e., calculated losses equal 101.79% of actual losses. 18
1 The sum of energy SPS sold to customers and delivered to interconnections with other utilities at the points
the energy left the SPS transmission and distribution system, collectively “Sales.” “Sales” thus include deliveries of power produced by suppliers other than SPS to transmission-only customers.

spreadsheets frequently display rounded data, but use the unrounded data in the calculations.
Exhibit No. SPS-0004 Page 6 of 18
Q. HAS SPS SUBMITTED THE 2016 LOSS STUDY TO ITS STATE REGULATORY 1
AGENCIES? 2
A. Yes. As discussed in the Direct Testimony of Mr. Wesley L. Berger, SPS submitted the 3
2016 Loss Study to the PUCT and the NMPRC, and these commissions accepted the loss 4
factors derived from the 2016 Loss Study in orders issued in 2018. SPS proposes to 5
revise the wholesale real power loss percentages set out in the Xcel Energy Tariff to be 6
consistent with the 2016 Loss Study and the loss factors used to calculate retail rates to 7
provide consistency across SPS’s three jurisdictions (FERC, Texas and New Mexico). 8
Q. WHAT ARE ELECTRICAL “LINE LOSSES”? 9
A. As electrical current flows from a generation source to customers’ loads, it passes 10
through wires and transformers that have an inherent electrical resistance to the flow of 11
electricity. This electrical resistance causes some of the energy flowing in the system to 12
be converted to heat and is, thereby, “lost.” Total losses are the difference between the 13
electrical energy put onto the T&D system and the electrical energy that was either sold 14
to customers or delivered to exit points on the utility’s T&D system. For example, if a 15
utility generates 1,000 MWh and experiences overall losses of 6%, it will deliver only 16
940 of the 1,000 MWh generated. The 60 MWh difference between the amounts 17
generated and delivered to customers are the T&D losses. Such losses are an inherent 18
characteristic of a properly functioning electrical system and are unavoidable. 19
Q. IN YOUR EXAMPLE, WOULD EACH TYPE OF CUSTOMER CAUSE THE 20
UTILITY TO LOSE 6% OF THE ENERGY GENERATED? 21
A. No, not generally, and not on SPS’s system. In order for electricity to reach a typical 22
residential customer, it must flow from the generator through generation unit main 23
Exhibit No. SPS-0004 Page 7 of 18
transformers, then through bulk transmission lines and related autotransformers, then 1
through transformers at a distribution substation, then through primary distribution lines, 2
then through a pole top transformer, then through a secondary distribution line from the 3
pole top transformer to a pole behind the residence, and finally through a service line 4
from the pole to the meter on the side of the house. At each step, losses are incurred to 5
serve the residential customer. 6
By contrast, to reach a wholesale or industrial customer taking service at 230 7
kilovolts (“kV”), the electricity has to flow through only the generation unit main 8
transformer, some bulk transmission lines, and a 345/230 kV autotransformer. None of 9
the losses incurred at distribution substations, primary distribution lines, distribution 10
transformers, secondary lines, and service lines are experienced in serving an industrial 11
customer taking service at transmission voltage. Thus, in general, customers taking 12
service at higher voltages cause fewer losses to be incurred than do customers taking 13
service at lower voltages. 14
On the SPS system, customers take service at multiple voltages ranging from 230 15
kV to 120 volts. For example, on the SPS system, a wholesale customer may take service 16
at transmission voltages from 230, 115, or 69 kV. Wholesale customers may also take 17
service at various distribution voltages from 34 to 2.4 kV. A wholesale customer taking 18
service at a transmission voltage should only be required to pay for the losses incurred as 19
the power moves from the generators through the transmission system (or through the 20
distribution system for wholesale loads served at distribution voltage). 21
Exhibit No. SPS-0004 Page 8 of 18
Q. DO UTILITIES IN GENERAL, AND SPS IN PARTICULAR, HAVE METERS 1
INSTALLED AT EACH STEP IN THE ELECTRICAL FLOW DESCRIBED 2
ABOVE SO THAT LOSSES AT EACH STEP CAN BE MEASURED? 3
A. No. In general and on SPS’s system, meters exist at generators, at locations where SPS’s 4
transmission lines interconnect with transmission lines of other utilities, and at points of 5
delivery to customers. Thus, SPS can use meters to measure the total electrical energy 6
placed on its T&D system, whether from generators located within or outside its system, 7
and the total energy Sales. The difference between total Resources and total Sales is the 8
actual loss incurred. 9
Given that meters do not exist at each step at which losses are incurred, a loss 10
evaluation study is performed to quantify, through engineering analysis and calculations, 11
the power and energy losses that occurred at the different loss levels on the T&D system 12
during the study period. The calculated loss values for each loss level are used with the 13
undeterminable losses (discussed later) to assign the proper portion of actual losses to 14
Loss Level 2 through Loss Level 6 discussed below. 15
Q. WHAT CIRCUIT ELEMENTS OF SPS’S ELECTRICAL SYSTEM WERE 16
ANALYZED IN THE 2016 LOSS STUDY? 17
A. The circuit elements analyzed were: (1) the transmission lines, (2) the transmission 18
autotransformers, (3) the distribution substation transformers, (4) the distribution primary 19
feeder circuits, (5) the distribution line transformers, and (6) the distribution secondary 20
lines and service lines. 21
Exhibit No. SPS-0004 Page 9 of 18
Q. YOU STATED THAT THE 2016 LOSS STUDY CALCULATES LOSSES AT 1
SEVERAL LEVELS. PLEASE IDENTIFY THE LOSS LEVELS AND THE 2
CIRCUIT ELEMENTS CONTAINED IN EACH LOSS LEVEL. 3
A. Loss Level 1 is the generator and generator step-up transformer and no losses are 4
calculated at this level because the Backbone Transmission is considered the delivery 5
point of the electricity from the generator. Loss Levels 2 through 6 and the circuit 6
elements in each loss level are identified below. 7
Loss Level 2 – Backbone Transmission 8
• Bulk transmission lines (345 kV, 230 kV, and 115 kV); and 9
• Autotransformers (345/230 kV and 230/115 kV). 10
Loss Level 3 – Sub-Transmission 11
• 69 kV transmission lines; and 12
• Autotransformers (115/69 kV). 13
Loss Level 4 – Distribution Primary 14
• Transformers located at distribution substations; and 15
• Primary Distribution Lines (“feeders”) (34.5 kV – 2.4 kV). 16
Loss Level 5 – Distribution Secondary Transformers 17
• Transformers located on primary distribution lines. 18
Loss Level 6 – Distribution Secondary and Service Lines 19
• Secondary distribution lines running from Level 5 transformers to other poles or 20
service points and service lines running to the customers’ premises. 21
The losses at Levels 5 and 6 are combined to create a “Distribution Secondary” 22
classification. 23
Exhibit No. SPS-0004 Page 10 of 18
Q. YOU NOTED THAT THE 2016 LOSS STUDY COVERED A 12-MONTH 1
PERIOD. IS IT APPROPRIATE TO PERFORM A LOSS EVALUATION STUDY 2
OVER A PERIOD SHORTER THAN 12 MONTHS? 3
A. In general, no. The loss evaluation study must correlate energy generated and purchased 4
for customers with Sales to those customers. SPS bills some customers every normal 5
business day of each month. Customers are usually billed once per month; however, the 6
billing period start and end dates do not always respect the calendar month boundary. 7
The billing period may cover part of a previous calendar month or may only cover part of 8
the current month, with no overlap into a previous month. When all Sales are totaled and 9
compared to that billing month’s generation and power purchases, there will be a 10
difference, which may be a positive or a negative number. This difference does not 11
necessarily reflect the actual losses incurred on the T&D system during this billing 12
month. This precludes doing a loss evaluation study for a short period of time. 13
Q. HOW DOES A LONGER TIME PERIOD AID IN PREPARING A LOSS STUDY? 14
A. By using a longer time period, such as one year, the effects of the different customer 15
billing cycles are minimized. I would note that the previous 2009 and 2013 loss studies 16
used to update the SPS loss factors included in the Xcel Energy Tariff in 2012 (Docket 17
No. ER12-1682-000) and 2016 (Docket No. ER16-1030-000) also used historic one year 18
study periods. 19
Exhibit No. SPS-0004 Page 11 of 18
Q. DID THE 2016 LOSS STUDY CONSIDER LOSSES OF CUSTOMERS 1
OPERATING THEIR OWN TRANSMISSION AND/OR DISTRIBUTION 2
SYSTEMS? 3
A. No. SPS evaluated losses up to the customers’ meters but not beyond, because SPS does 4
not incur the losses that occur beyond the customers’ meters. 5
Q. PLEASE DESCRIBE THE METHODOLOGY USED TO DETERMINE THE 6
TRANSMISSION SYSTEM LOSSES. 7
A. For peak demand losses, the 2016 summer peak was modeled with powerflow studies and 8
the losses per circuit element were tabulated and grouped by voltage category. Any loss 9
contribution due to no-load losses was also calculated. For energy losses, the Study 10
Period was divided into four time segments consisting of whole months, and average 11
loads were computed for each time segment. Powerflow studies determined the losses 12
for each circuit element for the average load during each of the four segments. The 13
average loss per circuit element was determined and multiplied by the hours in the load 14
segment to determine the energy losses. The months included in each load segment are 15
identified in Appendix A of Exhibit No. SPS-0005. 16
Q. WHAT ARE “NO-LOAD LOSSES”? 17
A. Whenever a transformer is energized, a relatively small loss occurs even during hours 18
when no load current is passing through the transformer. These losses are referred to as 19
“no-load losses.” Since transformers are typically energized every hour of the year, no-20
load losses must be calculated for each transformer in order to accurately estimate losses 21
incurred at each transformer location. 22
Exhibit No. SPS-0004 Page 12 of 18
Q. WHERE ARE TRANSMISSION LEVEL LOSSES DISCUSSED IN THE 2016 1
LOSS STUDY? 2
A. The circuit elements (i.e., lines and transformers) of the transmission system are 3
identified in Section 1.1 of Exhibit No. SPS-0005, and the process for calculating 4
transmission level losses for each type of circuit element is discussed in Sections 4 5
through 5. 6
Appendix M of Exhibit No. SPS-0005 presents a summary of losses for each type 7
of circuit element at both transmission and distribution levels. 8
Energy losses by level are stated in Appendix O of Exhibit No. SPS-0005 in the 9
column labeled “kWh Loss by Level” and Levels 2 and 3 are the transmission voltage 10
levels. 11
Losses for individual transmission circuit elements are tabulated in Appendices E, 12
F, and G of Exhibit No. SPS-0005. 13
The summary results of the powerflow studies are in Appendix N of Exhibit No. 14
SPS-0005. 15
Q. PLEASE DESCRIBE THE METHODOLOGY USED TO DETERMINE THE 16
DISTRIBUTION SYSTEM LOSSES. 17
A. Peak demand and energy losses were calculated for the elements in the distribution 18
system and accumulated based on a typical representation of SPS’s distribution system. 19
Losses were calculated for the distribution substation transformer, the primary feeders, 20
the secondary system (including distribution transformers), and the service lines to the 21
customers. The annual energy loss was determined by calculating annual energy loss per 22
Exhibit No. SPS-0004 Page 13 of 18
distribution element and summing up the total energy loss. Similarly, demand losses 1
were determined on each component of the distribution system and aggregated. 2
Q. WHERE ARE DISTRIBUTION LEVEL LOSSES DISCUSSED IN THE 2016 3
LOSS STUDY? 4
A. The circuit elements (i.e., lines and transformers) of the distribution system are identified 5
in Section 1.1 of Exhibit No. SPS-0005, and the process for calculating losses for each 6
type of circuit element is discussed in Sections 6 through 10. 7
Appendix M of Exhibit No. SPS-0005 presents a summary of losses for each type 8
of circuit element at both transmission and distribution levels. 9
Energy losses by level are stated in Appendix O of Exhibit No. SPS-0005 in the 10
column labeled “kWh Loss by Level” and Levels 4, 5, and 6 are the distribution voltage 11
levels. 12
Losses for individual distribution circuit elements are tabulated in Appendices I, 13
J, K, and L of Exhibit No. SPS-0005. 14
Q. WHAT ARE THE RESULTS OF THE 2016 LOSS STUDY? 15
A. Total actual losses for the Study Period were 1,914,545 MWh, and the losses determined 16
through the 2016 Loss Study’s engineering analysis were 1,948,829 MWh. The 17
undetermined losses are the difference, -34,284 MWh, which is -1.79% of the actual 18
losses. See Appendix M of Exhibit No. SPS-0005, Line No. 44 for total actual losses, 19
Line No. 42 for total determined losses, and Line No. 43 for undeterminable losses. 20
Exhibit No. SPS-0004 Page 14 of 18
Q. CAN YOU DETERMINE THE REASON FOR THE -34,284 MWH DIFFERENCE 1
BETWEEN THE LOSSES CALCULATED IN THE 2016 LOSS STUDY AND THE 2
ACTUAL LOSSES INCURRED? 3
A. No. Undeterminable losses are equal to the Total Actual Losses minus the Total 4
Determined Losses (calculated losses). The -34,284 MWh of undeterminable losses 5
cannot be assigned to any particular cause. A loss evaluation study is an engineering 6
analysis of line losses attributable to average electrical loadings of particular components 7
of the T&D system. There is always a difference between the actual and calculated 8
losses, which can be positive or negative, between the results of a computer analysis 9
using average loads and the actual line losses experienced. The small 1.79 percent 10
difference between the actual losses and calculated losses indicates the 2016 Loss Study 11
reasonably represents the losses on the SPS T&D systems. 12
Q. ARE UNDETERMINABLE LOSSES TAKEN INTO ACCOUNT IN 13
DETERMINING LOSS FACTORS? 14
A. Yes. The loss factors must be based on actual losses to ensure correct fuel factors. Thus, 15
the undeterminable losses, whether positive or negative, are assigned to the circuit 16
elements for which losses have been calculated in the study based on the ratio of each 17
circuit element’s calculated loss to the total of all calculated losses. The results of this 18
assignment process appear in Appendix M of Exhibit No. SPS-0005 in the “Adjusted 19
Energy MWH” and “Factored KWH” columns. The totals for those columns tie to the 20
Total Losses on Line No. 66 of Appendix A of Exhibit No. SPS-0005. 21
Exhibit No. SPS-0004 Page 15 of 18
Q. DID ANY OF THE DATA OR METHODS USED TO CALCULATE LOSSES IN 1
THE APPENDICES OF THE 2016 LOSS STUDY CHANGE FROM THE DATA 2
USED IN THE 2013 LOSS STUDY? 3
A. Yes, there are always changes in data from one study to the next. Changing the Study 4
Period changes much of the data, e.g. generation amounts, power purchases, peak load, 5
powerflow case results, Sales data, miles of T&D lines, customer meter counts, etc. The 6
updated data are reflected in the appendices of the 2016 Loss Study. 7
The SPS T&D systems modelled in the 2016 Loss Study have experienced four 8
major changes since the 2013 Loss Study. 9
• First, there was significantly more wind and solar generation connected to 10 SPS’s transmission system in 2016 than in 2013. The effect of this additional 11 generation injecting power into the transmission system at different locations 12 than in the past has a significant effect on losses. 13
• Second, a significant amount of wind and solar generation has been connected 14 to the SPS distribution system since the 2013 Loss Study. This wind and solar 15 generation delivers energy directly to the distribution system in contrast to the 16 historical norm of nearly all the energy flowing through the transmission system 17 into the SPS distribution system. 18
• Third, three new 345 kV lines that significantly strengthen the SPS connection 19 to the rest of the SPP grid were placed in service in 2014. The installation of 20 these transmission lines has allowed SPS and other wholesale load serving 21 entities (“LSEs”) on the SPS system to purchase significant amounts of low-cost 22 energy from the SPP Integrated Marketplace and import that power into the SPS 23 system. These imports could significantly change the flows on the SPS 24 transmission system and therefore affect losses. 25
• Fourth, there have been changing patterns of power delivery on SPS’s system. 26 Recently, SPS has been transmitting more wholesale customer-procured power 27 than in the past. 28
Exhibit No. SPS-0004 Page 16 of 18
Q. DID ANY OF THE METHODOLOGIES USED TO CALCULATE LOSSES IN 1
THE APPENDICES OF THE 2016 LOSS STUDY CHANGE FROM THE 2
METHODOLOGIES USED IN THE 2013 LOSS STUDY? 3
A. Yes. While the majority of the fundamental methodologies did not change, the increase 4
in generation connected to the SPS distribution system from 2013 to the present Study 5
Period has required a change in study methodology to accurately account for losses. 6
In previous studies, nearly all the generation was connected to the transmission 7
system and the generated energy flowed through the transmission system to the 8
distribution system. This energy flow scenario is shown graphically in Figure DJR-1: 9
10 Figure DJR-1 Historical SPS Energy Flow 11
In Figure DJR-1, 100 MWh of energy flows through the transmission system to the 12
distribution system, resulting in transmission losses in proportion to the 100 MWh flow 13
of energy. 14
In the 2016 Loss Study, a significant amount of generation had been connected to 15
the SPS distribution system, delivering energy directly to the distribution system. In this 16
simplistic example, the energy delivered directly to the distribution system does not cause 17
losses in the transmission system, resulting in lower transmission losses than in the 18
scenario shown in Figure DJR-1. This new energy flow scenario is shown graphically in 19
Figure DJR-2 (next page): 20
Exhibit No. SPS-0004 Page 17 of 18
1 Figure DJR-2 2016 Loss Study Energy Flows2
In Figure DJR-2, only 95 MWh of energy flows through the transmission system to the 3
distribution system, while 5 MWh of energy is generated and delivered directly to the 4
distribution system. This scenario results in transmission losses from only 95 MWh of 5
energy flow instead of 100 MWh as in the first scenario. 6
In the 2016 Loss Study, the significant increase in generation connected directly 7
to the distribution system necessitated a change in the study methodology to account for 8
this change in the energy flows. The Loss Study now includes data in Appendix B of 9
Exhibit No. SPS-0005 that summarizes the energy and demand delivered directly to the 10
distribution system. Updates were made to the spreadsheets in the Excel workbook to 11
reflect this change in flows so that the resulting loss calculations are accurate. The 12
methodology used in the 2016 Loss Study shows the generation connected to the 13
distribution system flowing into the distribution system at the low voltage side of the 14
distribution substation transformer. 15
Exhibit No. SPS-0004 Page 18 of 18
Q. WAS THERE ANY CHANGE IN THE TREATMENT OF WHOLESALE 1
TRANSACTIONS WITH ENTITIES OUTSIDE OF SPS’S SERVICE AREA? 2
A. No. The same net metering approach was used in the 2016 Loss Study as was used in the 3
2013 Loss Study. 4
IV. CALCULATION OF LOSS FACTORS 5
Q. WHAT ARE “LOSS FACTORS”? 6
A. A loss factor is simply a number, which when multiplied by a given amount of Sales, 7
yields the amount of energy that must be generated to produce the Sales amount. If, for 8
example, losses at a specific service level are 10%, then 100 MWh have to be generated 9
to yield 90 MWh of Sales. Thus, the loss factor at that level is 1.1111 (90 MWh sold x 10
1.1111 loss factor = 100 MWh generated). 11
Q. DOES THE 2016 LOSS STUDY CONTAIN CALCULATED LOSS FACTORS? 12
A. Yes. The Energy Loss Factor and the Demand Loss Factor for each SPS loss level are 13
shown in Appendices O and P of Exhibit No. SPS-0005. Loss factor derivation is 14
discussed in Section 12.0 of Exhibit No. SPS-0005. These loss factors were calculated 15
using the same methodology as in previous loss studies. 16
In his Direct Testimony, Mr. Berger discusses the necessary adjustments to the 17
results of the 2016 Loss Study he made to arrive at the real power loss factors (stated on a 18
loss percentage basis) SPS is proposing in this filing to include in the Xcel Energy Tariff. 19

1.0 Overview This report discusses an evaluation of transmission and distribution system losses for
the 12 month period January – December 2016 (2016 Study Period). This evaluation
was designed to be as introspective as technically possible and provide a significant
level of confidence in determining the electrical losses on the Southwestern Public
Service (SPS) transmission and distribution systems. This evaluation determines
actual losses and then uses engineering principles to calculate both demand and
energy losses at specific voltage levels.
SPS operates an electrical system consisting of 345 kV, 230 kV, 115 kV and 69 kV
transmission lines and a distribution system with lines operating at 33 kV to 2.4 kV. The
system spans a large 52,000 square mile area from the Oklahoma panhandle through
the Texas panhandle and into eastern and southeastern New Mexico. SPS has
generation on both 230 kV and 115 kV busses throughout this area. Since 2009 SPS
and other power producers have installed significant wind and solar generation within
the SPS boundary. Most of this generation is connected at transmission voltage levels
and some at distribution primary voltage levels. The scope of this study was to
determine the demand and energy losses for the following components:
Transmission System Components:
Generation Unit Main Transformers
Transmission Lines
Autotransformers
Distribution System Components:
Distribution Substation Transformers
Distribution System, including Primary, Secondary and Service Lines
Transformers

The losses related to these elements of the power system are frequently seen in
accounting reports as "Unaccounted For Energy." The purpose of this study is to
determine actual losses and then specifically assign losses by the components
identified above for the 2016 Study Year.
The losses of customer-operated transformers, transmission systems and distribution
systems are not considered in this study. Any losses occurring in auxiliary busses at
power plants are not considered in this study.1 Also, losses related to the generator
step-up transformers are not included since net generation is recorded at the high
voltage side of these transformers.
The analysis of losses requires consideration of both demand, or power, losses and
energy losses. The demand losses are typically measured in megawatts (MW),
kilowatts (kW), or watts. The energy losses are measured in megawatt-hours (MWh),
kilowatt-hours (kWh), or watt-hours (Wh). Certain components of the energy losses are
present even though there is very low electrical load passing through the device. An
example of this is the magnetizing current and related losses of a transformer. After the
transformer is energized, these losses will occur. Power flow through the transformer
will increase the losses, but even in the absence of any power flow, the transformer will
experience “no-load losses” simply because it is energized.
To provide a basis for the calculations in this study, data was gathered for the
transmission and distribution systems. This data and associated calculations are
shown in the Appendices of Attachment DJR-RD-2. All references in this document to
a specific appendix are found in Attachment DJR-RD-2. Each Appendix corresponds to
a section of the total loss calculation or provides data used in other appendices. Actual
counts exist for the devices and miles of electric lines that cause losses at the
transmission level. The calculation of losses at the transmission level involves very little
engineering judgment. Actual counts of devices and line data exist for much of the
Exhibit No. SPS-0005 Page 4 of 95
Southwestern Public Service Company Loss Evaluation Study for 2016 Study Period
3
distribution system as well. In some cases, however, data does not exist for the
distribution system and engineering approximations or judgments must be and were
made to determine losses at specific voltage levels. These approximations are noted in
the discussion.
1.1 Loss Levels The energy losses for each physical category (lines, transformers, etc.) are grouped by
the six Loss Levels. These Loss Levels, which are shown in Appendix H, are:
Loss Level 1 - Generation
Loss Level 2 – Backbone Transmission
Loss Level 3 – Sub - Transmission
Loss Level 4 - Primary Distribution
Loss Level 5 - Secondary Distribution Transformers
Loss Level 6 - Secondary Distribution Lines
Losses are not calculated at Level 1. The other levels are composed of the following
physical loss categories:
Loss Level 2 – Backbone Transmission
345 kV, 230 kV and 115 kV Transmission Lines
345/230 kV, 230/115 kV Autotransformers
Loss Level 3 – Sub - Transmission
69 kV Lines
115/69 kV Autotransformers
Loss Level 4 - Primary Distribution
Distribution Substation Transformers
Distribution Primary Lines (33 kV to 2.4 kV lines)
Loss Level 5 - Secondary Distribution Transformer
Distribution Line Transformers
Loss Level 6 - Secondary Distribution Lines
1 Auxiliary busses are distribution busses which provide internal power plant distribution service for internal power
Exhibit No. SPS-0005 Page 5 of 95
Southwestern Public Service Company Loss Evaluation Study for 2016 Study Period
4
Distribution Secondary and Service Lines
Transmission losses are those at Levels 2 and 3. Losses attributable to distribution
facilities are those calculated for levels 4, 5 and 6. In setting loss factors for rate
classes, the losses calculated at levels 5 and 6 are combined and a composite loss
factor is determined.
The results of the 2016 Loss Evaluation Study are shown in Appendix M and the rate
class loss factors derived from the study are in Appendix Q.
1.2 Determination of Actual Losses Appendix A contains the determination of actual losses measured in MWh for the total
transmission and distribution system based on 2016 Study Period operating data. The
general definition of losses is the difference between the total resources and total
deliveries. Specifically, the Total Resources, shown in Appendix A, are:
Net Generation (line 6) – metered output of SPS’s generating plants
Net Metered SPP Interchange and WECC HVDC Interchange (lines 7 & 8) –
metered physical flows at all interchange tie points with the Southwest
Power Pool (SPP) and the Western Electric Coordinating Council
(WECC). Wherever SPS’s transmission system interconnects with
transmission systems of other utilities in the SPP or WECC, meters exist
and data are captured to determine the energy either flowing into or out of
SPS’s system. The net flows into or out of the SPS system at these
boundaries account for any purchases made from, or sales made to,
entities outside the SPS boundary. In addition, if third parties enter into a
sale and purchase transaction and SPS’s transmission system is used to
deliver power, the net metered flows at SPS’s boundaries will reflect the
plant equipment (i.e. water wells, internal plan equipment, plant controls, pumps, etc.).

use of the transmission system by recording the inflow and the
corresponding outflow. This process of calculating the net flows into or
out of SPS’s system is referred to as “net metering.”
Firm Purchased Power BEA, LPP (line 11) – SPS purchases energy pursuant to the contracts
with Borger Energy Associates and Lea Power Partners, LLC.
LPL Generation (line 12) – SPS has a full requirements sales contract
with West Texas Municipal Power Agency (WTMPA), an entity
established by the cities of Lubbock, Tulia, Brownfield, and Floydada.
SPS also contracts with the City of Lubbock to purchase the output of
three Lubbock generating plants that operate only when requested by
SPS. This generation is located within the Lubbock Power & Light (LPL)
network and no SPS loss is attributable to this power. Line 12 is the total
Lubbock generation during the 2016 Study Period.
Others (line 13) – SPS purchases relatively small amounts of energy from
a number of other entities located within its system boundary pursuant to
firm contracts. The collective purchases under these contracts are
reported on this line.
Renewable Energy Purchases (lines 14-21) – these are energy purchases
from renewable sources that have firm network transmission service.
Other Generation inside the SPS Boundary Golden Spread Electric Cooperative (GSEC) owns the Mustang Plant
near Denver City, Texas, and Antelope and Elk Stations located near
Abernathy, Texas. GSEC has also purchased the output of the
Panhandle Wind Ranch. Lines 23-27 show the GSEC resource outputs
Exhibit No. SPS-0005 Page 7 of 95
Southwestern Public Service Company Loss Evaluation Study for 2016 Study Period

for the 2016 Study Period. Since the GSEC generation is within SPS’s
boundary, its generation must be included in total area resources to
prevent an under-statement of resources due to the net metering process
described above.
Lea County Electric Cooperative (LCEC) Generation This is renewable and fossil generation output that is connected to
LCEC’s 115 kV transmission line from SPS Hobbs Plant to SPS Denver
City Substation. This is shown on lines 29-31.
Farmer’s Electric Cooperative (FEC) Generation This renewable generation is connected to FEC’s transmission system
and the value reported is the excess generation above FEC’s load that
flows back onto the SPS transmission system. This is shown on lines 33-
34.
Export Renewables The output of these renewable generators is scheduled or purchased by
other companies outside of the SPS boundary. These energy values are
shown on lines 36-42,
SPS Non-Firm Purchased Power Lines 44-50 represent the output of various generators that are being
purchased by SPS and flow onto the SPS transmission system.
Market Renewables Lines 52-56 represent generators located within SPS’s boundary sending
power over SPS’s transmission lines into the SPP Energy Market. Like
GSEC’s generation, this generation must be included in SPS’s total
Exhibit No. SPS-0005 Page 8 of 95
Southwestern Public Service Company Loss Evaluation Study for 2016 Study Period
7
resources to prevent an under-statement of resources due to the net
metering process described above.
The sum of these resources is the “Total Resources” (line 58) available on SPS’s
system for serving customer load within its system boundary.
Total Deliveries (line 64) consists of all retail sales, all full requirements wholesale sales
within the system boundary, and all deliveries to Golden Spread load points within the
system boundary.
Total Losses (line 66) are the actual losses experienced during the 2016 Study Period.
Total Losses are calculated by subtracting the Total Deliveries on line 64 from the Total
Resources on line 58. This value of Total Losses is the value that will be used to
generate the loss factors by voltage level.
SPS’s Total System Loss percentage during the 2016 Study Period is shown on line 67.
This value is derived by dividing Total Losses (line 66) by Total Resources (line 58).
The “Net Output to Lines by Load Segment” data (lines 77-89) are simply the sums of
monthly values for “Net Output to Lines” (line 74) for the months contained in each
segment. The determination of segments is discussed in Section 3.1 and the Net
Output to Lines by Load Segment data are used in determining transmission line losses
in Section 4.3.
1.3 Distribution Connected Generation Sources
Appendix B contains a list of distribution-connected resources that deliver power
directly onto the SPS distribution system at the primary level. These resource values
Exhibit No. SPS-0005 Page 9 of 95
Southwestern Public Service Company Loss Evaluation Study for 2016 Study Period

are used in the calculation of losses on the distribution system, specifically in Appendix
J – Distribution Primary Loss.
2.0 Generation Step-Up Transformer Losses Losses attributable to these transformers are included in station power and are not part
of this study.
3.0 System Load Analysis To determine the transmission line and autotransformer losses, it is necessary to
perform powerflow studies at different system load levels throughout the year. The
system loading levels must be determined before these studies can be done. For the
period under study, the system loads are obtained from the operations center. The
load represented in these studies is a composite of SPS retail load, GSEC and other
wholesale loads within the SPS system boundary.
Any other sale or purchase of energy that either started in or was received into the SPS
boundary, and including any through transactions from the east to west or west to east
across the SPS system between the eastern and western grids are included when the
powerflow models are developed to capture any transmission losses due to those
transactions.
SPS’s daily minimum and maximum load are summed to produce a daily average load.
Then the corresponding values for tie line flows are obtained and summed for the same
hour. This produces a daily minimum and daily maximum load to be analyzed. The
results of this procedure are shown in Appendix D – System Load Data 6, Daily
Maximum/Minimum Loads graph.
3.1 Segment Derivation
Exhibit No. SPS-0005 Page 10 of 95
Southwestern Public Service Company Loss Evaluation Study for 2016 Study Period

The daily maximum and minimum loads are still too detailed for the powerflow analysis,
since there are 366 minimum and 366 maximum values for each load (2016 is a leap
year). The next step is to produce a daily average load graph. The Average Value
Analysis graph is shown in Appendix D – System Load Data 6. The average load is
graphed for the study period. Then an average study value is fit to the graph. The goal
of this fit is to minimize the sum of the errors between the average load values to be
used in the study and the actual daily average load. Once this has been determined,
the year can be broken into load segments which will be modeled in the powerflow
program using the values of average load determined here. The load segments will
typically be a spring period, summer period, and a fall/winter period. It is required that
the segment boundary fall on whole calendar months because the all the data is based
on a calendar month, For the 2016 Study Period, the best fit to model the loads for the
12 months was a four segment model. The sum of the errors in the 2016 Study Period
is 0.28%. See Appendix D - System Load Data, line 8. The segment values used in
this analysis were:
Segment 1: January - February 3380 MW
Segment 2: March - May 3323 MW
Segment 3: June - August 4432 MW
Segment 4: September - December 3387 MW
The average loads per segment, number of days in each segment and other values
used in the analysis are shown on the chart in Appendix D - System Load Data.
3.2 Powerflow Loss Calculations
Once the segment loads have been determined, the powerflow analysis can be
performed. The average segment load values determined above are used for the loads
in the powerflow studies. Powerflow cases are run on each of the load segments under
study. The generation patterns are varied between the segments to better represent
Exhibit No. SPS-0005 Page 11 of 95
Southwestern Public Service Company Loss Evaluation Study for 2016 Study Period
10
the mix of generators actually on-line at that time of the year. There is also a peak
powerflow case prepared to analyze the system losses at the hour of the system peak.
The powerflow program used to perform studies is Power Technologies Inc.’s PSS/E
program. Once the powerflows have been completed, the losses are summarized for
the SPS system. The loss values for each transmission element and voltage class are
tabulated for the peak hour case and for each segment period. The summary
tabulations are shown in Appendix N. These losses represent the loss for that element
for the segment load used. These values are then used to determine the transmission
line and transformer losses.
Excluded from the loss tabulation are transmission systems that are not owned by SPS,
but reside inside SPS’s boundary and modelled in SPS’s powerflow program. These
systems are Lea County Electric, Lubbock Power and Light, and Tri-County Electric
Cooperative.
4.0 Transmission Line Losses The losses on transmission lines consist of several parts. Demand and energy losses
on the transmission system consist of corona losses, insulator losses, and losses due
to power flow through the transmission lines. These losses are tabulated by
transmission voltage level in Appendix E.
4.1 Transmission Line Corona and Insulator Losses
Transmission systems have losses due to corona and insulator leakage. Corona loss
occurs when the voltage gradient near the conductor surface exceeds the breakdown
strength of the surrounding air. Insulator leakage is the small current that flows across
the surface of the insulators attached to the electric conductor. The Transmission Line
Reference Book published by Electric Power Research Institute contains information on
determining the representative losses associated with corona and insulator leakage.
Exhibit No. SPS-0005 Page 12 of 95
Southwestern Public Service Company Loss Evaluation Study for 2016 Study Period
11
Using that reference, losses per mile for each transmission voltage level were
determined and entered in the “KW Loss/mile” column. Transmission line mileage was
taken from FERC Form 1 data. The demand loss due to corona and insulator leakage
(Appendix E, “Demand Losses” column) is calculated by multiplying the kW loss per
mile for a specific voltage level times the miles of transmission operating at that voltage
and then dividing that product by 1,000 to yield a MW loss result. The energy loss is
simply the demand loss times the number of hours per year. For 345 kV transmission
lines, for example, the corona and insulator demand loss of 2.121 MW in Appendix E is
the rounded value of this equation: (2.343 kW loss/mile x 905.42 miles) ÷ 1,000. The
annual energy loss (18,634 MWH) for these same elements is the product of 2.121 MW
(the unrounded value from the previous equation) x 8,784 hours/year.
4.2 Transmission Line Demand Losses The losses calculated for transmission lines are shown in Appendix E, labeled
Transmission Line Demand Loss. The peak demand losses were determined by
tabulating the megawatt losses per transmission line as shown in the 2016 Study
Period peak powerflow study in Appendix N. These losses are tabulated by voltage
class.
4.3 Transmission Line Energy Losses The energy loss for the transmission lines at each voltage level is determined by using
the losses developed in the powerflows for each load segment. The segment loads are
listed in Appendix E along with the net output of power to the transmission system
during the segment. This value was determined in Appendix A and labeled “Net Output
to Lines By Load Segment.” The Net Output to Lines by Load Segment is the amount
of generated and purchased energy put onto the transmission system to serve load.
The determination of the energy losses for transmission lines of a specific voltage in a
specific segment is calculated using the following equations.
Exhibit No. SPS-0005 Page 13 of 95
Southwestern Public Service Company Loss Evaluation Study for 2016 Study Period
12
Segment Loss Factor = MW Load, Segment
MW Element, onTransmissi for Loss Segment (4.3.1)
Segment Losses = MWH Lines, to Output Segment Factor Loss Segment × (4.3.2)
Thus, the powerflows provide a determination of the energy loss as a single value for
each segment. Dividing the segment loss by the segment load produces a per MW
energy loss factor. Multiplying this per MW energy loss factor by the Segment Output
to Lines produces the energy loss for that element in that load segment. The energy
loss values for the year are simply the sum of the energy loss values for each element
in each load segment and appear in Appendix E on lines 37-43 under the column
heading “Total Segment Losses, MWH.”
5.0 Autotransformer Demand Losses SPS’s transmission system autotransformers reduce voltage from one transmission
voltage to a lower transmission voltage. The high side and low side autotransformer
voltages are typically written as “345/230,” “230/115” and “115/69.” See, e.g., Appendix
G, column heading “Voltage”, lines 2, 11 and 41. Each autotransformer in SPS’s
transmission system is identified in Appendix G. The load losses related to
autotransformers can be separated into demand and energy components.
The demand component was determined in two steps. The first step was to determine
the total demand loss for each voltage level of autotransformers from the summer peak
powerflow study, summarized in Appendix N. This provided the MW loss due to loading
at the peak time of the year. These losses are shown for each of three voltage classes
of autotransformers at lines 3, 5 and 7 of Appendix F.
The second component of the autotransformer demand loss was provided by summing
the individual transformer no-load demand losses for the different voltage classes of
Exhibit No. SPS-0005 Page 14 of 95
Southwestern Public Service Company Loss Evaluation Study for 2016 Study Period
13
individual transformers in Appendix G in the three columns under column heading
“Demand Losses, KW.” This component represents the demand loss incurred by
simply energizing the transformer, as described below.
5.1 Autotransformer Energy Losses The energy losses related to autotransformers can also be separated into two parts.
The first part is the energy loss associated with no-load operation. This is the energy
loss due to the magnetizing currents that exist when a transformer is energized. These
losses were determined by multiplying the no-load loss in Watts as shown under
column heading “No Load Loss, Watts” in Appendix G by the number of hours in the
2016 Study Period because these autotransformers are assumed to be energized
throughout the study period.
The energy losses related to loading were determined using the same methodology as
for transmission lines. For each powerflow study, a tabulation of the autotransformer
demand losses by voltage level was calculated. A segment loss factor for each
segment was calculated by dividing the MW Loss by the Segment Load in Appendix F.
The autotransformer energy losses for each segment were calculated by multiplying the
segment loss factor by the Segment Output to the Lines for that segment. This
produces the average energy losses for each voltage level for each segment. The data
needed to make these calculations and the results are shown in Appendix F. The
equations used to obtain the energy losses for the autotransformers are the same as
Equations 4.3.1 and 4.3.2.
All losses discussed to this point are transmission level losses. The losses discussed in
the following sections 6 through 10 are losses at the distribution level.
Exhibit No. SPS-0005 Page 15 of 95
Southwestern Public Service Company Loss Evaluation Study for 2016 Study Period
14
6.0 Distribution Substation Transformer Losses Distribution substation transformers are those transformers that reduce the
transmission voltage, e.g., 69 kV, to a distribution voltage, such as 33 kV, 22 kV or 12.5
kV. The data for each distribution substation transformer are in Appendix I.
Manufacturers’ data were used to determine losses. If manufacturers’ data were not
available for a specific transformer, data for a similar transformer manufactured by
another company were used.
Column 9 has a code for verification of data. The codes used in this field mean:
R - ratings were verified from manufacturer’s data
L - loss values were verified from manufacturer’s data
E - loss values are an estimate
There are many transformers on SPS’s system that are either owned by a specific
customer or have metering or other arrangements to reflect the billing on the high side
of the transformer, i.e., before losses are incurred. These transformers are excluded
from the loss calculations in Appendix I, and excluded from Appendix I’s list of
transformers, because SPS does not incur the losses associated with these
transformers (the losses are borne by the customer leasing the transformer). In some
situations, only a portion of a transformer’s capacity is leased, and thus, only a portion
of the losses associated with that transformer should be excluded. These transformers
are identified by the letter “E” in column 10 of Appendix I, and the percentage of losses
to be excluded is stated in column 15. The letter “I” in column 10 means that all of the
transformer’s losses are included in the loss calculations.
6.1 Distribution Substation Transformer Demand Losses The demand losses associated with these transformers have two components. The
first component is the magnetizing current losses that are present anytime the
transformer is energized. The second component is the full load loss value for the
transformer. Manufacturers’ test report data was used to determine the no-load loss
Exhibit No. SPS-0005 Page 16 of 95
Southwestern Public Service Company Loss Evaluation Study for 2016 Study Period
15
and the loss when the distribution transformers were loaded to their nominal MVA
ratings (Appendix I, column 4). Loading of transformers at their nominal MVA rating is
referred to in Appendix I as “full load” but this label does not mean that the transformers
have no additional capacity. The maximum MVA loading for each transformer is listed
in Appendix I, column 5. As evidenced by the differences between the values in
columns 4 and 5 of Appendix I, many transformers can handle loads in excess of their
nominal “full load.” The no-load losses and nominal “full load” losses for each
transformer are tabulated in Appendix I, columns 6 and 7, and totaled for the entire
system near the bottom of Columns 6, 7, and 8 on line 302.
It was assumed for the purposes of this study that the distribution transformers were
operating at “full load” (their nominal MVA ratings) at the time of the system peak. This
assumption was reasonable, conservative, and necessary. The transmission and
distribution system is designed to handle the system’s peak load and have additional
capacity available in case peak load is greater than forecasted. And, of course,
system load has grown since most of these transformers were originally sized and
installed. Thus, at the time of system peak, it is likely that many transformers operated
somewhere between their nominal and maximum MVA ratings. Thus, basing losses
upon only the nominal MVA loading, as SPS has done, is conservative. Using this
assumption was necessary since manufacturers typically provide test data only for
losses at the nominal MVA rating.
6.2 Distribution Substation Transformer Energy Losses The energy loss has two components. The first is the no-load loss, which occurs during
every hour of the Study Period. Referring to Appendix I, this value was calculated by
multiplying the no-load losses derived from manufacturers’ test data, column 6, by the
number of hours in the Study Period, which results in the energy loss during the Study
Period, as shown in column 12.
Exhibit No. SPS-0005 Page 17 of 95
Southwestern Public Service Company Loss Evaluation Study for 2016 Study Period
16
The full load loss required the determination of the load characteristic of the load being
served by a particular transformer. The load factor assigned to each transformer is
shown in Appendix I, column 11.
The load factor for a study period is defined as:
Load Factor = Period Study in Hours Demand Max.
Delivered Energy Period Study Total ×
(6.2.1)
For the purpose of determining the study period energy losses, the following equation
was used:
Losses = Full Load Loss Hours in Period Load Factor × × (6.2.2)
The results of this calculation are shown in Appendix I, column 13.
The “Sum of demands adjusted for Primary Generation” is the estimated load at
primary and shown on line 305. The 47.291 MW adjustment shown on line 304 is the
coincident wind and solar primary generation from Attachment B at system peak hour
and it thus reduces the total flow on the primary feeders. This generation connected to
the primary voltage level may all flow into the primary voltage level and never get
transformed to the transmission voltage level.
6.3 Calculation of Load at Each Feeder Voltage Level The load at each feeder voltage level is calculated at lines 312-319 of Appendix I. The
loading on 33 kV feeders, for example, is calculated by determining the ratio of the
nominal MVA of transformers connected to 33 kV feeders (153.30 MVA on line 314) to
the adjusted nominal MVA of all distribution substation transformers (3,026.08 on line
314) and then multiplying that ratio by total loading on all distribution feeders (line 305).
Thus, for 33 kV feeders, the calculated loading is: (153.30/3,026.08) x 2,206.35 MW =
Exhibit No. SPS-0005 Page 18 of 95
Southwestern Public Service Company Loss Evaluation Study for 2016 Study Period
17
111.77 MW. This value appears at line 315, column 2 of Appendix I. From this value,
the load on transformers with no feeders (line 316) is subtracted to yield the load on 33
kV feeders, which appears on line 319. Line 317 shows data on total numbers of
feeders at each voltage level and line 318 shows the number of feeders after excluding
the portions of transformers that are shared with customers.
7.0 Load Factor Derivation The load factor used to calculate the study period full-load energy losses reflected in
Appendix I, column 11, provides a representative load factor for substation loads.
However, the load factor is not a pure load factor, such as might be found for a rate
class. Rather it represents the composite mix of customer load which occurs on the
power system. This load factor is calculated in Appendix H.
The data used in Appendix H comes from rate analysis of each customer class on
SPS’s system for the Study Period. Using this data, monthly demand peaks and
monthly energy deliveries, a composite load is developed which represents the desired
substation class load. With the summed energy and demands, a load factor can be
calculated. The annual load factor for primary distribution, Loss Level 4 is shown in
Appendix H, line 78 under table column heading “Total Loss Level 4.”
8.0 Distribution Primary Feeder Losses The primary distribution system (Level 4 in the loss study) includes the distribution lines
(feeders) that transport power from the distribution substation to the distribution line
transformers near each customer. The losses associated with these primary
distribution feeders are calculated on Appendix J. At the top of Appendix J, the
distribution loads and energy are summarized for the Study Period. They are broken
into loss levels and they represent the demand and energy for each level of the
distribution system. These values shown are derived from Appendix H and they will be
Exhibit No. SPS-0005 Page 19 of 95
Southwestern Public Service Company Loss Evaluation Study for 2016 Study Period
18
used throughout the distribution loss calculations. On lines 2 and 9, the demand and
energy values are offset by the distribution connected generation, obtained from
Appendix B.
Losses are calculated for 552.10 feeders operating at 6 nominal voltage levels (33 kV,
22 kV, 13.2 kV, 12.5 kV, 4.16 kV and 2.4 kV). There are 573 feeders connected to the
transformers (Appendix I, line 317), but some feeders are connected to transformers
whose capacity is shared with customers. Thus, the number of feeders at each voltage
level has been reduced in proportion to the nominal MVA of substation transformers at
each voltage level leased by customers. The percentage of each transformer’s
capacity leased to a customer is shown in column 15 of Appendix I. This process
produces fractional feeders that are used to calculate primary distribution feeder losses.
8.1 Distribution Primary Feeder Demand Losses The number of feeders and load at each distribution voltage level are derived from lines
318 and 319, respectively, of Appendix I.
The Feeder Current, in amps, is:
Feeder Current = Feeder Load3 Feeder Voltage( ) ×
(8.1.1)
The Feeder Loss, in watts, for a given voltage level is:
Feeder Loss = Length Average Resistance x Current) (Feeder 3 2 ×× (8.1.2)
The length of each feeder varies considerably as do the wire sizes (conductors) used in
the construction, which affects resistance. The distribution system database consists of
552 feeders ranging in length from zero to 48.6 miles and many different wire sizes and
materials. The typical conductor size was determined by summing the feeder lengths
Exhibit No. SPS-0005 Page 20 of 95
Southwestern Public Service Company Loss Evaluation Study for 2016 Study Period
19
by voltage and by conductor type and size, selecting the most common conductor
based on length and conductor material and size. The results of this investigation
appear under the column heading “Typical Conductor” in Appendix J.
The average feeder length was determined by sorting the feeders by voltage and
dividing the sum of the lengths by the number of feeders in each voltage range. A
feeder was counted if the length was greater than 0.05 miles. There were 552 feeders
that fit this criterion. The results of this investigation appear under the column heading
“Avg. Feeder Length, Miles” in Appendix J.
The total loss for a given voltage level is obtained by multiplying the loss determined
above by the number of feeders in the given voltage level.
8.2 Distribution Primary Energy Losses
These losses were calculated by multiplying the demand energy loss for the entire load
served via primary distribution line by the hours in the study year and by the loss factor
for the entire distribution load. The load factor is determined in Appendix J from the
Total Primary Demand and the Total Energy. Note that the Total Primary Demand and
Energy have been offset by the distribution primary connected generation from
Appendix B. The Loss Factor is determined by the following equation:2
Loss Factor = ( 0.3 x Load Factor) + ( 0.7 x (Load Factor)2) (8.2.1)
Thus, the losses over the year are determined by the following equation:
Loss = Factor Loss hours 8784 Loss Demand ×× (8.2.2)

20
Appendix K contains the loss calculations for distribution line transformers, which
corresponds to Loss Level 5. The number of meters and transformers are actual
counts derived from SPS’s records. The meters per transformer data is derived by
dividing the adjusted meter count by the number of transformers, e.g., 331,812 single
phase meters/97,184 transformers equals 3.41427 meters/transformer.
In calculating losses, it is necessary to distinguish between single phase transformers,
which serve primarily residential customers, and three phase transformers, which serve
primarily commercial customers. The “Adjusted Meters” column on Appendix K
performs this function by assigning the single phase commercial meters to the
“Residential” category, i.e., Residential Adjusted Meters equals actual residential
meters (301,809) plus the difference between all commercial meters and three phase
commercial meters (30,003).
It was assumed that one residential customer took service directly from each
distribution line transformer and that all other residential customers were served from
secondary distribution lines. Secondary lines are the lines that typically run from a pole
top transformer to another pole that has no transformer. From that second pole, a
service line runs to the customer’s premises. Losses on secondary lines and drops are
addressed in Appendix L. For three phase commercial customers, the number of
transformers essentially equals the number of meters, and thus, each such customer is
assumed to be served directly from the transformer.
9.1 Distribution Line Transformer Demand Losses Based on consultation with distribution system engineers, typical transformer sizes were
chosen as 25 KVA (residential) and 100 KVA (commercial). The transformer loss data
at no load and “full load” for each size are listed in Appendix K at lines 26 and 27. The
average load per customer is developed by taking the demand served and dividing by
the number of customers. Then the loss per transformer is developed by taking the
load per customer and calculating the losses proportionally to the load served by the
Exhibit No. SPS-0005 Page 22 of 95
Southwestern Public Service Company Loss Evaluation Study for 2016 Study Period
21
transformer and its full load rating. The total demand loss is determined by multiplying
the number of transformers by each no-load and full load loss component. The no-load
and loaded losses are shown at Appendix K, lines 35 and 37, and totaled at lines 39
and 41.
9.2 Distribution Line Transformer Energy Losses These losses were calculated by using the demand energy loss for the distribution line
transformers and multiplying by the loss factor of the load served through the
distribution transformers and by the number of hours in the Study Period. The load
factor is determined from data in Appendix K using the Total Secondary Distribution
Transformer Demand and the Total Secondary Distribution Transformer Energy. The
Loss Factor is determined from equation 8.2.1. Thus, the losses over the year are
determined by the following equation.
Loss = Factor Loss hours 8784 Loss Demand ×× (9.2.1)
10.0 Distribution Secondary Losses The distribution secondary losses are determined in Appendix L. To determine the
secondary losses, it was estimated that the secondary conductor was 1/0 MCM ACSR
conductor and that there was 60 feet of conductor serving each residential meter not
served directly from the transformer. The resistance of this secondary was 0.0127
ohms. The typical residential load and current and the commercial load and current
were determined in Appendix K. There is no consideration of commercial load on
secondary lines, as these customers are usually served directly from transformers.
10.1 Distribution Secondary Demand Losses There was assumed to be 2 meters per 60 foot of secondary line. The loss, in watts, on
the secondary was determined by the following equation:
Exhibit No. SPS-0005 Page 23 of 95
Southwestern Public Service Company Loss Evaluation Study for 2016 Study Period
22
Loss = ( )2 I2 R × × (10.1.1)
Multiplying by the number of meters (Appendix K) produces the total loss for the
distribution secondary.
10.2 Distribution Service Line Demand Losses It was estimated that residential service line consisted of 65 feet of #2 Triplex and
commercial service line consisted of 30 feet of #1/0 Quadraplex service wire. The
resistances for these service lines are 0.02028 ohms and 0.00636 ohms, respectively.
The current for each type of customer is calculated and the losses are calculated by the
following equations:
Loss = 2 I R 2× × , for residential customers and (10.2.1)
Loss = 3 I R 2× × , for commercial customers (10.2.2)
The total loss for each group was determined by multiplying the loss per meter by the
number of meters, which are found on Appendix K.
10.3 Distribution Secondary and Service Lines Energy Losses These losses were calculated by adding the demand loss of both the Secondary and
Services and multiplying by the number of hours in the test year and also multiplying by
the loss factor of the load that is served by Secondary and Services. The load factor is
determined from data in Appendix L using the Total Secondary Distribution Transformer
Demand and Total Secondary Distribution Lines demand and their associated energy.
The Loss Factor is determined from equation 8.2.1. Thus, the losses over the year are
determined by the following equation.
Loss = Factor Loss hours 8784 Loss Demand ×× (10.3.1)
Exhibit No. SPS-0005 Page 24 of 95

The results of this calculation are shown in Appendix L.
11.0 Summary of Transmission Loss Study Appendix M contains the results of all of the calculations discussed previously. The
power system elements for which losses are determined are:
Transmission Lines
Autotransformers
Distribution Substation Transformers
Distribution Primary Lines
Distribution Line Transformers
Distribution Secondary and Service Lines
Line 42 shows the total of the loss values obtained by the study, labeled as “Total
Determined Losses” or calculated losses. Line 44, labeled “Total Losses,” is the actual
energy losses determined in Section 1.2 of this report. The difference between the
results of this study and the actual losses is shown on line 43 as “Undeterminable
Losses”. Typically, the results from a loss study will be within a few percent, plus or
minus, of the actual losses. For the 2016 Study Period, the Total Determined Losses
are over estimated by 1.79% of actual losses. It should be noted that nowhere in
this study is the actual loss value used to force the loss study to produce a final
answer equal to the actual loss value.
The results of this study are used to determine loss factors for the different rate
classes. To do this, the calculated losses must be adjusted to total to the actual losses,
and thus, the Undeterminable Losses (Appendix M, line 43) have to be allocated to
Loss Levels 2 through 6. Each category of energy losses is allocated a portion of the
Undeterminable Losses equal to the ratio of that category’s calculated losses to Total
Determined Losses in MWh. For example, the “Adjusted Energy MWh” value for
Transmission Lines – 345 kV (line 14), which is 80,473 MWh, is determined by: 81,914
Exhibit No. SPS-0005 Page 25 of 95
Southwestern Public Service Company Loss Evaluation Study for 2016 Study Period
24
MWh (line 14 determined energy loss) x (1,914,545 MWH Total Losses /1,948,829
MWH Total Determined Losses).
The values in Appendix M under the column headings “Demand Total Loss, KW” and
“Energy Total Loss, kWh” are used in the development of the rate class loss factors.
12.0 Loss Factor Derivation Appendices O and P contain the derivation of the rate class loss factors from summary
data derived in various sections of the report. The rate class loss factors are
determined for the loss levels shown in Appendix O and P.
The method to determine the loss factors is based on starting with the total resource
input to the system at Generation Level, Level 1. This value is the starting point for the
worksheet. Using Appendix O as an example, from this value, the deliveries for that
level and the losses for that level are subtracted, leaving the ‘Net KWH into each Loss
Level’. This calculation is done for each loss level, with the result that all losses and
deliveries have been subtracted from the Total Resources, with a result of zero. This
means that all deliveries and losses have been assigned to a loss level and there is no
error. Loss factors are calculated at each level as the subtraction progresses to the
right through the loss levels. The calculation is shown in the appendices along with the
loss factors by rate classification.
The process of calculating the Demand Loss Factor in Appendix O is the same as
described for the energy factor calculation. However, rather than redistributing the
energy “Undeterminable Losses” among the different loss levels, the Demand MW from
line 42 Appendix M is used.

summarized form, without their respective derivations. The composite loss factors are
shown for rate classes in loss levels 5 and 6.
