TRANSCRIPT
1 decontamination of contaminated systems, e.g., ,using aggressive chemical solvents
2 to dissolve corrosionfilms holding radionuclides, thereby reducing radiation levels.
3 While effective, the on-site decontamination processes are nof expected to
4 reduce residual, radioactivity to the levels necessary to release the material as clean
5 scrap. Therefore, all contaminated components will have to be removed for
6 controlled burial. However, decontamination will reduce personnel exposure and will
7 permit workers to operate in the immediate vicinity of most components, cutting and
8 removing them for controlled disposition at a low-level radioactive waste burial
9 facility.
10
Contaminated piping to and from major components will be cut and removed.
11
Selected major components such as the reactor coolant pumps, steam generators,
12
pressurizers, and other large 6omponents will then tie removed intact and sealed so
13
that they may be transported off-site. Smaller components, such as sampling
14
system pumps, filters, filter housings, strainers, etc., will be loaded into containers
15
and shipped for controlled disposal.
16
The reactor vessel and its internals will be segmented and remotely loaded
17
into,steel liners for transport to the burial facility in heavily shielded shipping casks.
18
The =reactor vessel and internals will have sufficiently high radiation levels to require
19
all cutting to be done underwater or behind heavy shields, using cutting tools
20
operated by remote control to reduce radiation exposure to the workers.
21
Concrete immediately surrounding the reactor vessel is expected to be
22
radioactive and will be removed by controlled blasting. This blasting process is well
23
developed, safe, and is the most cost effective way to remove the heavily-reinforced
24
concrete from the structure.
25 Some surfaces of sections of interior floors within areas of the Containment
26 and other buildings in the power block are expected to be contaminated from
21 DIRECT TESTIMONY OF FRANCIS W. SEYMORE
600
1 exposure to contaminated air/water as a result of plant operations. This
2 contamination will be removed by scarification (surface removal) so that the
3 remaining surfaces will be cleaned to release levels and will not require disposal as
4 Class A radioactive waste.
5 Contaminated process equipment, pipe hangers, supports, dnd el,ectrical
6 components will be removed and routed for controlled disposal.
7 Finally, an extensive radiation survey will be performed to ensure all
8 radioactive materials above the levels specified by the NRC have been removed
9 from the site. With NRC confirmation, the NRC license for Most of the site (excluding
10 the ISFSI) will be terminated.
11
12 C. Period 3 — Site Restoration
13, This period begins once license termination activities have concluded and
14 involves the demolition of all remaining structures, typically to a depth, of three feet
15 below grade. Clean concrete rubble would be used on-site for fill and additional soil
16 would be used to cover each subgrdde structure. Excess rubble is trucked, off-site
17 for disposal.,
18
19 D. Post Period 3 — Spent Fuel Storage
20 The ISFSI wilF pontinue to operate under a Part 50 license following the
21 transfer of the spent fuel inventory from the Fuel Building. Transfer of spent fuel to a
22 DOE or interim facility will be exclusively from the ISFSI once the fuel pools have
23 been emptied and the struciures 'released for decommissioning. Palo Verde will
24 continue shipping spent fuel canisters to DOE through the year 2098.
25 At the conclusion of the spent fuel transfer process, the ISFSI will be
26 decommissioned. TLG's estimate includes the cost to decommission the ISFSI. In
22 DIRECT TESTIMONY OF FRANCIS W. SEYMORE
601 ,
the ISFSI, the spent fuel assemblies are contained within stainless .steel canisters.
2 On the IŠFSI pad, these canisters are housed within reinforced concrete and steel
3 shield cylinders khown as gverpacks. The canisters are assumed to 'be removed,
4 shipped, and disposed of by the DOE. The steel overpack liners are assumed to
5 have some level of neutron-indUced, activation as a result of the long-term storage of
6 the fuel, i.e., to levels exceeding free-release limits. As an allowance, seven
7 overpacks per unit (site total of 21) are assumed to require remediation, equivalent to
8. the number of overpacks required to accommodate the final core- offloads at Palo,
9 Verde (241 assemblie5 per unit for a site total of 723 assernblies).. The cost of the
10 disposition of, this material, as well as the demolition of the ISFSI facility, is included
11 in. the estimate. The NRC will terminate the remaining license if it determines that
12 site remediation has been performed in accordance with a license .termination plan
13 and the terminal radiation survey and' associated documentation demonstrate that
14 the facility meets the release criteria. Once the requirements are satisfied, the NRC
15 can terminate the remaining license for the ISFSI.
16 The remaining reinforced concrete dry storage modules are then demolished,
17 the concrete storage pad,is removed, and the area graded and landscaped to 11.
18 conform to the surrounding environment.
19 '
20 Q. HOW DOES THE PRESENCE OF SPENT FUEL ON SITE AFTER PLANT
21 SHUTDOWN AFFECT THE DECOMMISSIONING PROCESSES?
22 A. Although the study does not address the transport or disposal of spent fuel from the
23 •Palo Verde site, it does consider the:constraint that the presence of spent fuel on the
24 site can impose on other decommissioning activities. •In particular, the
25 decommissioning scheduling developed in support of the last four cycles of cost
26 updates for• the Palo Verde estimates incorporates an APS request for a six-year
23 DIRECT TESTIMONY OF FRANCIS W. SEYMORE
• 602
1 rninimum cooling prerequisite for off-loading the fuel from the storage pools. As
2 such, these spent.fuel management activities will necessarily delay the final release
3 of the power blocks-for alternatiVe/unrestricted use. This delay is reflected in the
4 increased cost of the period-dependent activities. To the extent possible, the
5 decommissioning estimates were structured around the spent fuel areas of the units
6 and their availability for decontamination, such that delays in decommissioning other
7 portions of the facility could be minimized. Decommissioning would proceed on the
8 surrounding facilities and non-essential systems during the approximately six-year
9 pool off-load period. The operating licenses can then be amended with the.
10 remaining fuel placed in dry storage.
11 Some small portion of the existing.Palo Verde site will continue to be licensed
12 by the NRC under the existing Part 50 license for the ISFSI. The endpoint of this
13 storage period is estimated to be in 2098. Following this, the ISFSI will be
14 decommissioned, the license terminated, and the concrete storage casks and pads
15 crushed and removed.
16
17- Q. DOES THE PROCESS OF DECOMMISSIONING EXTEND BEYOND REMOVAL OF
18 CONTAMINATED AND ACTIVATED MATERIAL FROM THE SITE?
19 A. Yes. There are additional activities .beyonct the removal of contaminated' material
20 that will be undertaken in the process ofreleasing the šite for alternative use. This
21 work includes costs for the remaining dismantling and .grading operations and is
22 generally referred to assite restoration.
23
24 Q. PLEASE DESCRIBE THE SITERESTORATION ACTIVITIES.
25 A. These activities begin once license termination activities have concluded and involve
26 the demolition of all remaining structures, typically to a depth of three feet below

grade. Clean concrete rubble generated from the demolition of the Containment,
Auxiliary, Fuel, Radwaste, and Turbine Buildings, etc., would be used on-site for fill
and additional soil would be used to cover each subgrade structure. Excess rubble
is trucked off-site for disposal. Either any below grade structures will be removed, or
voids below grade, such as the 31-mile buried water line from Phoenix to the Water
Reclamation Facility, will belilled with sand or concrete. The object is to prevent any
future surface subsidence.
Once the below grade features of the site have been addresed, the surface
of the site will be graded to conform to the surrounding environs. The evaporation
and makeup water reservoir walls will be breached to prevent retaining water. At thie
point, the site is available for reuse, except for the footprint otthe ISFSI.
WHY WERE THE REMAINING STRUCTURES ON SITE ASSUMED TO BE .
DISMANTLED?
Efficient removal of the contaminated materials and verification that the radionuclide
concentrations are below the stringent NRC limits will require substantial damage to
many of the structures. Blasting, coring, drilling, scarification (surface removal), and
the other décontamination work will damage power block structures including the
Containrnent, Radwaste, Auxiliary, •and Fuel Buildings. Verifying that subsurface
radionuclide concentrations meet NRC site release requirements may require
removal, of grade slabs and lower floors, potentially weakening footings and
structural supports.
It is also important 4o remember that the Palo Verde-structures were custom
designed and built to supp'Ort a specific nutlear unit design that went into service in
the 1980s. They would most likely be an impediment rather than a benefit to any
potential future plant, if one were ever to be constructed at the site. Moreover, the
25 DIRECT TESTIMONY OF FRANCIS W. SEYMORE
604
1 facilitys infrastructure degrades without continual maintenance. Unless the site is
2 redeveloped shortly after release of its NRC license, the value in reusing plant
3 facilities quickly diminishes.
4 As demonstrated by U.S. experience, dismantling is clearly the most
5 appropriate and cost-effective option and should serve as the foundation for the
6 decommissioning cost estimates. It is unreasonable to anticipate that these
7 structures would be repaired and preserved after the radiological contamination is
8 removed.
9
10 Q. WHAT ASSURANCE IS THERE THAT THE ESTIMATED COST' FOR
11 DECOMMISSIONING WILL REFLECT FUTURE DEVELOPMENTS AND
12 INCREASES OR DECREASES IN COSTS?
13 A. The cost estimate prepared for Palo Verde is based on present technology, the
14 current information available on decornmissioning costs, and on existing federal
15 regulations. No provision is made to include future costs or savings due to the
16 uncertainties in improvements in technology, major regulatory changes, inflation
17 factors, etc. It should be noted that the contingency, as used in the estimates, only
18 covers uncertainties within the decommissioning schedule timeframe.
19 ,
20 VII. RECOMMENDATIONS
21 Q. IS IT NECESSARY TO SELECT A SPECIFIC DECOMMISSIONING METHOD• AT
22 THIS TIME?'
23 A. No. The .actual method or •combination of methods selected to decommission
24 Palo Verde should be based on a detailed. economic, engineering, and
25 environmental evaluation of the alternatives considering the site and surroundings at
26 the time of decommissioning and reflecting the latest experience in the
26• DIRECT TESTIMONY OF FRANCIS W. SEYMORE
605
1 decommissioning of similar nuclear power facilities. The owners of Palo Verde will
2 make such evaluations near the time of final.shutdown of the units.
3
4 Q. WHAT ARE YOUR RECOMMENDATIONS?
5 A. I recommend that, for planning purpose§, the decommissioning cost funding be
6 based upon reinoval of Palo Verde using- the DECON alternative. This alternative
7 provides the most reasonable mbans for amending/terminating the license for the
8 site in the shortest possible time. Furthermore, this alternative avoids the long-term
9 costs and commitments associated with the maintenance, surveillance and security
10 requirements of the conventional delayed dismantling alternatives. The Commission
11 has adopted the DECON alternative as a basis for ,funding nuclear plant
12 decommissioning in every case in which a TLG witness has testified.
13 The DECON alternative also allows use of the plants knowledgeable
14 operating staff, a valuable asset to a well-managed, efficient decommissioning
15 program. Equipment needed to support decommissioning operations such as
16 cranes, ventilation. systems, and radwaste processing equipment would be fully
17 operational. In addition, the site would be available for other use in the near term,
18 with the exception of the area immediately surrounding the plants fuel storage,
19 facility.
20
21 VIII. CONCLUSION
22 Q. PLEASE SUMMARIZE YOUR ;TESTIMONY.
23 A. In 2016, TLG performed site-specific cost estimates for the decommissioning of
24 Palo Verde. The total estimated cost for the decommissioning in 2016 dollars was
25 $2,739.1 million. The study shows an increase of approximately $330 million dollars,
26 or 13.7 percent, from the 2013 estimate. These amounts includes costs to remove
27 DIRECT TESTIMONY OF FRANCIS W. SEYMORE
1 all radioactive materials from the site which exceed the release criteria, terminate the
2 NRC operating licenses, remove all structures above the three foot below grade
3 elevation and backfill all below grade voids to the surface elevation, transfer all spent
4 fuel from all three Fuel Buildings to the on-site ISFSI, operate thisiSFSI until 2098
5 (excluding ISFSI security and operating staff and ISFSI operating expenses, which
6 •are assumed to be recovered from the DOE and therefore not included), and
7 decommissiOn the ISFSI following removal of all spent fuel and GTCC material by
8 the DOE, currently estimated to occur in the year 2099..
10 Q. DOES THIS CONCLUDE YOUR TESTIMONY?
11 A. Yes, it does.

EXECUTIVE SUMMARY
Cynthia S. Prieto, Director of Tax for El Paso Electric Company (the. "Company" or
"EPE"), presents the payroll -and tax schedules and amounts included in the cost of service
and deferred tax amounts considered 'in the determination of rate base for the Company for
the historical Test Year. In her testimony,..she specifically discusses:
• Federal and State Income taxes included in'.Cost of Service
• Tax and Payroll Schedules provided in the Rate Filing Package (RFP"),
• Taxes Other Than Income
Federal and state income tax expense included in EPE's cost of service. has been
calculated using • the "return" method for the historical Test Year, as required by the
Instructions and Schedules, to the RFP. This refurn, method calculation reflects a
"stand-alõne" approach that includes in cost of service only federal and state income taxes
that result from the provision of utility service to customers. Ms., Prieto demonstrates that it
is neither appropriate nor equitable to increase or reduce cost of service by tax costs or
benefits that are not related to the rendition of utility service to custorners.
'Use of the return method also .satisfies the provisions ,of PURA § 36.060. In -the
Companys filing, requested tax expense is based solely on the income and expenses used
in determining the Companys revenue requirement and rate base. The Companys
stand-alone method ensures that customers benefit from the tax deductions that are
generated by the expenses included in cost olservice. This approach is reasonable and fair
for all parties.
Ms. Prieto demonstrates that the federal and state income tax schedules that are
part of the CompanY's filing are in compliance -with the prescribed RFP and are in
accordance with the Substantive Rules of the Public Utility Commission of Texas (pucr).
Adjustments made to tax expense, cost of sei-vice, and to rate base are both reasonable
and appropriate:

Ms. Prieto also explains that the treatment of state deferred income taxes is iñ
compliance with the Final Order in PUCT Docket No. 44941.
In her discussion of "taxes other than income," Ms. Prieto discusses th.e Test Year
property tax amount and demonstrates that the remaining "revenue-related taxes,"
(e.g., local franchise fees, sales, ,use and gross receipts taxes and other miscellaneous
taxes plus state regulatory assessments) are reasonable and necessary.
in her discussion of payroll schedules Ms. Prieto describes the calculation of- the
salaries and wages and payroll taxes included in the revenue requirement including all
applicable proforma adjustments.

20 III. BACKGROUND OF INCOME TAX ACCOUNTING AND RATEMAKING
21 Q. CAN YOU PLEASE DESCRIBE THE ACCOUNTING" FOR INCOME TAXES
22 REQUIRED UNDER GENERALLY ACCEPTED ACCOUNTING PRINCOLES
23 ("GAAP")?
24 A. Yes. Accounting for income taxes under GAAP is contained in the Accounting
25 .Standards Codification ("ASC") in section ASC 740 (formerly SFAS No. 109,
26' Accounting for Income Taxes ("SFAS 109)). There are several components to the
3 DIRECT TESTIMONY OF CYNTHIA S. PRIETO
620
1 calculation: currently payable income taxes, deferred income taxes, and investment
2 tax credits.
3
4 Q. WHAT IS THE FIRST COMPONENT, CURRENTLY PAYABLE INCOME TAXES?
5 A. Currently, payable income tax expense represents the estimated amount of current
6 year income taxes payable based on current year taxable income. Taxable income
7 for -ihe year is determined in accordance with the Internal Revenue Code ("IRC").
8 For purposes of preparing an income tax return each year, the- IRC contains
9 procedures for determining if and when an item is "taxable-or "deductible."
10
11 Q. WHAT IS THE SECOND COMPONENT, DEFERRED INCOME TAXES?
12 A. The IRC rules for determining what is taxable or deductible rnay differ from what is
13 reportable as -"revenue" or "expense" under GAAP. For instance,. certain expenses
14 recorded on the financial statements under GAAP in.one year may be dedUctible on
15 the tax return in. a different period. There are also instances where the amounts
16 shown as deductions on the tax. return in one year are not reflected on the financial
17 statements until a later year. As a result; at the end of each reporting period, there
18 will likely be accumulated differences.of reported assets and liabilities resulting frorn,
19 different book and tax return treatment of revenues and expenses. These
20 differences are referred to as temporary differences.
21
22 Q. CAN YOU FURTHEI3 EXPLAIN WHAT IS MEANT BY THE TERM "TEMPORARY
23 DIFFERENCES" AND PROVIDE AN EXAMPLE?
24 A. Yes. One common temporary difference iš depreciation. For book purposes, GAAP
25 requires that the asset be depreciated over-its estimated useful life in a sSisternatic
26 and rational manner. As a result, straight-line depreciation. over the useful life- of
4 DIRECT TESTIMONY OF CYNTHIA'S. PRIETO
621
1 assets is used for book purposes. For income, tax purposes, the asset may be
2 depreciated using an accelerated depreciation method which is generally shorter
than the estimated useful life. Initially, tax depreciation will exceed book
4 depreciation. In the later years, the reverse will be true because given the same
5 capitalized asset cost, over the life of the asset total depreciation will be the same.
6
7 Q. WHAT IS THE ACCOUNTING FOR TEMPORARY DIFFERENCES UNDER
8 ASC 740?
9 A. Under GARP, because the financial statements reflect accrual and not cash basis
10 accounting, deferred income taxes are recorded on temporary. differences. As a
11 result, income tax expense under GAAP includes both a currentlji payable,
12 component (as previously described, based on the.tax return) as well as a "deferred"
13 income tax component (based on temporary differences). Such- deferred, income
14 taxes reflect the liability or asset forincome taxes payable or receivable in the future
15 stemming from transactions recorded in the financial statements currently. The
16 balance sheet liability or asset- for future taxes is referred to as Accumulated
17 i Deferred Income Tax ("ADIT'). In other words; to the extent that accelerated tax
18 depreciation iš claimed on the income tax return in an amount that exceeds book
19 depreciation reported on the financial statements, a liability for future taxes results.
20 This future tax liability is due to the fact that greater depreciation claimed in early
21 years will "use ur the tax basis of'assets and result in higher taxes in the future.
22 Under ASC 740, a calculation of required ADIT is performed at the end of
23 each reporting period. The required ADIT is measured by multiplying the temporary
24 differences by the currently applicable income tax rates. Comparing the ADIT at the
25 current balance sheet date to the ADIT at the previous balance sheet date results in
26 "deferred income tax expense." For regulated, entities, such as EPE, the process of
5 DIRECT TESTIMONY OF CYNTHIA S. PRIETO
622
1
recording deferred income taxes on temporary differences is referred to as
2
"normalization," "deferred tax accounting," or "comprehensive interperiod income tax
3
allocation."
4
5 Q. DOES CLAIMING DEDUCTIONS FOR INCOME TAX PURPOSES IN EXCESS OF
6 EXPENSES RECORDED FOR BOOK .PURPOSES PROVIDE INCENTIVES TO
7 THE COMPANY THAT BENEFIT CUSTOMERS?
8 A. Yes. By claiming tax deductions for such things as accelerated depreciation, the
Company reduces its current income tax payments. But, with respect to temporary
10 differences, tax payments will be higher in the future when the temporary differences
11 reverse. As a result, ADIT balances are "interest free loans" from the U.S. Treasury.
12 This was the objective Congress intended when it included accelerated depreciation
13 provisions in the IRC. Congress believed that allowing companies to increase their tax
14 depreciation deductions (and thereby reduce curreni income tax payments), would
15 lower the financing costs of their investment ih capital assets and thus they would be
16 incented to make such expenditures. For accounting purposes, using up the tax basis
17 of capital assets is both a cost to be recognized in the- financial statements when
18 claimed (i.e., deferred tax expense) and a liability for future taxes due when the
19 turnaround occurs and book depreciation exceeds tax depreciation (i.e., ADIT).
20
21 Q. ARE ALL BOOK/TAX DIFFERENCES "TEMPORARY DIFFERENCES" AND
22 SIMPLY A MATTER OF WHEN THE ITEM IS INCLUDED ON THE TAX RETURN
23 VERSUS WHEN THE ITEM IS SHOWN ON THE FINANCIAL STATEMENTS?
24 A. No. Most differences between their treatment on the books and ihcome tax return
25 are simply. "temporary" and over time, the same amount will be included on the
26 financial statements and tax returns. However, certain items of revenue and
6 DIRECT TESTIMONY OF CYNTHIA-S. PRIETO
623
1 expense are, over time, treated differently for financial reporting purposes than for
2 incorne tax purposes. These are referred to as permanent differences.
3
Deferred income taxes are not required on permanent differences. In the
4
period reported, current income taxes will be adjusted to reflect the jncreased
5 deduction or non-deductibility of these costs and there will be no deferred income
6 taxes since these amounts will "never" be included in the financial statements or
7 deducted on the tax retum thereby permanently decreasing or increasing current tax
8 expense.
9
10 Q. IS THE DISTINCTION BETWEEN PERMANENT AND TEMPORARY
11 DIFFERENCES IMPORTANT IN THE INCOME TAX CALCULATION?
12 A. Yes. Permanent differences need to bd separately identified and included in the
13 income tax. calculation because they 'do not require deferred income tax accounting,
14 and permanently increase or decrease total income tax expense that needs to be
15 recovered in revenue requirements in a rate case.
16
17. Q. IS THERE ANOTHER COMPONENT OF THE INCOME TAX CALCULATION?
18 A. Yes. In addition to current and deferred income taxes, a third element of the tax
19 computation is the Investment Tax Credit ("ITC").
20
21 Q. CAN YOU PLEASE SUMMARIZE WHAT THE ITC IS AND HOW IT IS TREATED
22 FOR ACCOUNTING/RATEMAKING PURPOSES?
23 A. The ITC, which has gone in and out of existence over.the years, lowers income tax
24 expense permanently, if ceqain qualifying investments are made. It, is intended as
25 an incentive for companies to invest in qualifying assets. To make. sure that its
7 DIRECT TESTIMONY OF CYNTHIA S. PRIETO
624
1 objectives are !net for regulated •utilities, the IRC prescribes methods of sharing the
2 benefit between customers and-shareholders.
3 The ITC is a direct reduction of incipme taxes payable in a given year. pnlike
4 accelerated depre9iation and other book/tax differences that will eventually reverse
5 or turn around, the ITC is comparable to a rebate. The ITC provides an incentive to
6 capital investment by granting a tax credit (a direct dollar-for-dollar• offset to current
7 taxes, payable) based on a percentage applied to investMent in tangible personal
property (most generation, transmission and distribution assets).
9 The accounting for the ITC is contained in ASC 740, codifying the accounting
10 for ITC -previously contained in Accounting Principles Board Opinions 2 and 4,
11 Accounting for the Investment Credit. Most utilities, like EPE, account for the ITC by
12 reducing current income taxes payable in the year the credit is earned for the full
13 amount of the credit but recognize an equal and offsetting amount of deferred tax
14 expense. The amount of the credit is then. amortized to reduce income tax expense
15 over the book life of the property giving rise to the ITC.
16 " In 1972, for ratemaking purposes, the IRS required utilities to elect how they
• 17 intended to share the ITC between customers and shareholders. Most utilities,
18 including EPE, elected to share the ITC as described in the preceding paragraph, by
19 including the annual amortization to income tax expense as a reduction to income tax
20 expense. In accordance with- this election, the unamortized ITC basis is not deducted
21 from rate base. Reduced income tax expense benefits customers when it is included in
22 . rates.
23
24 IV. NORMALIZATION REQUIREMENtS
25 .Q. WHAT IS THE FEDERAL ENERGY REGULATOIRY COMMISSION'S (FERC")
26 POSITION ON DEFERRED INCOME TAXES?
8 DIRECT TESTIMONY OF CYNTHIA S. PRIETO
625
-1 A. The FERC Uniform System of Accounts embraces "normalization" of deferred
income taxes by requiring comprehensive interperiod income tax allocation for all
3 book/tax timing/temporary differences. FERC Order Nos. 144 and 144A provide
4 guidance in this area. This has been the FERC methodology since the early 1980s.
5
6 Q. IS NORMALIZATION ACCOUNTING REQUIRED. FOR A UTILITY TO REFLECT
7 CERTAIN DEDUCTIONS AND CREDITS ON ITS FEDERAL TAX RETURN?
8 A. Yes. The IRC requires that regulated utilities rnust use the normalization method,
9 and not the flow-through method, to calculite the tax expense related to
10 depreciation-related temporary differences (IRC Section 168), Contributions In Aid of
11 Construction (IRS Notice 87-82), investment tax credits, excess deferred taxes, and
12 net operating losses (NOLus) created by accelerated depreciation in orderto avoid
13 certain penalties.
14
15 Q. IN THE PREVIOUS QUESTION, YOU MENTIONED THAT NOLS CREATED BY
16 ACCELERATED DEPRECIATION WERE REQUIRED TO BE NORMALIZED. IS
17 EPE IN A NOL CARRYFORWARD POSITION?
18 A. Yes. EPE is currently in a. NOL carlyforward position. EPE's NOL was created in
19 tax year 2015 and the Test Year from tax deductions which exceeded taxable
20 income. These deductions "arose from temporary differences related to accelerated
21 tax depreciation allowed by the extension of bonus depreciation in the Protecting
22 Americans from ,Tax Hikes Act of 2015 (PATH Acr), whiCh was signed into law
23 December 2015 and applicable retroactively to January 1, 2015.
24
25 Q. HAS EPE INCLUDED A NOL CARRYFORWARD ADIT ASSET IN RATE BASE IN
26 THE TEST YEAR?
9 DIRECT TESTIMONY OF CYNTHIA S. PRIÈTO
'626
1 A. Yes, it has,, consistent with IRS normalization requirements. When a company has
negative current taxable income, it cannot realize the cash benefit of all of its
3 deductions, because it cannot reduce its tax payments below zero. The NdLs must
4 be.deferred and carried forward to be used against taxable income in future periods,
5 subject to certain limitations. Only then will the taxpayer receive the cash tax benefit
6 of these NOLs. When carried forward, the NOL is'a temporary difference for which
7 an ADIT asset must be recorded. The net of the ADIT liability created by the bonus
8 •depreciation and the AD1T asset created by the NOL carryforward represents the
9 cash tax benefits that were actually received by the Company.
10
11- Q. WHAT IS THE PENALTY FOR VIOLATING THE IRS• NORMALIZATION
12 REQUIREMENT REGARDING NOLS?
13 A. The NOL normalization rules are a subset of the depreciation normalization rules,
14 therefore, a violation of the NOL normalization requirement would result in the loss of
15 the ability to ,u,se accelerated tax depreciation on all public utility property. held by the
16 utility.
17
18 V. FEDERAL INCOME TAXES
19 Q. 'HOW HAVE FEDERAL INCOME TAXES INCLUDED IN COST OF SERVICE BEEN
20 CALCULATED?
21, A. Federal income taxes have been calculated using the "return" method for the
22 historical year, as required by the Instructions and Schedules to the RFP.
23
24 Q. WHAT IS THE "RETURN" METHOD?
25 A. The calculation of federal income takes provided on Schedule G-7.8 is comrnonly
26 referred to as the "return" method because it calculates federal income taxes using
' 10 DIRECT TESTIMONY OF CYNTHIA S. PRIETO
627
after-tax return as the starting point. Under this method, equity retum, or total retum
2
less interest, is adjusted for items for which there is no tax deduction to offset
3
amounts recovered through revenues — such as book amortization of Allowance kr
4
Funds Used During Construction ("AFUDC") equity, "flow-through differences,"
5
permanent differences, ITC amortization, and the amortization of excess ADIT. The
6
"return" method calculates federal income tax expense in total, with no segregation
7
between current and deferred federal income taxes. The return method tax
8
calculation provided on Schedule G-7.8 reflects a stand-alone approach to
9
cglculating federal income taxes.
10
11 Q. WHAT IS THE BASIS FOR' THE PERMANENT DIFFERENCES INCLUDED IN THE
12. RETURN METHOD?
13 A. Permanent differences can arise when costs are reported as expenses in the
14 financial statements but will never be deductible on the income tax return. In
15 addition, permanent differences can also arise when deductions are allowed on the
16 income tax return that will never be reported as expenses in the financial statements.
17 Examples of permanent differences in EPE's tax Calculation are the cost of meals
18 and entertainnient and the domesti6 próduction'activities- deduction (DPAD"). The-
19 cost of meals and entertainment are reported as expenses in the financial
20 s-tatements but, under the IRC, are not completely deductible on the income tax
21 return and is therefore a permanent difference which increases current tax expense.
22 The ,DPAD is a deduction allowed by the IRC for domestic manufacturing activities
23 but is limited by several factors including taxable income. This deduction will never
24 be an expense in the GAAP financial statements and is therefore a perManent
25 difference which decreases current tax expense.
26
11 DIRECT TESTIMONY OF CYNTHIA S. PRIETO-
628
1 Q. WHAT IS MEANT BY A "STAND-ALONE" APPROACH?
2 A. The ."stand-alone" methodology calculates federal income taxes on utility revenues
3 and expenses that are included in the utility's revenue requirement. This approach
4 appropriately allocates federal income taxes between customers and shareholders
5 using the benefits/burdens criteria outlined by FERC Opinion No. 173. Under this
6 methodology, federal income tax expense relates to, and results from, the provision
7 of utility service to customers. Additionally, the "stand-alone federal income tax
8 calculation includes an adjustment -to synchronize interest. Synchronized interest
9 represents the portion of return that is deductible for -tax purposes and ie calculated
10 by multiplying'the weighted cost of debt by rate 'base. Use of synchronized interest
11 in the tax calculation effectively "synchronizes" the calculation of federal income tax
12 expense with rate base and' rate of return. Synchronized interest may be more or
13 less than the actual interest deducted on the tax return.
14
15 Q. WHY IS THE "STAND-ALONE" APPROACH THE PROPER METHODOLOGY TO USE
16 IN CALCULATING FEDERAL INCOMETAXES,FOR RATEMAKING PURPOSES?
17 A. The "stand-alone approach; required by Section 36.060 of the Public Utility
18 Regulatory Act ("PURA") as amended, in 2013, includes in cost of service only
19 federal income- taxes that result from the provision of utility service to customers.
20 Federal income taxes requested by the Company are based on revenues and
21 expenses included in the cost of service calculation. There are no additions to or
22 reductions from tax expense resulting from revenues or expenses notincluded in the
23 Company's request.' It is rieither appropriate nor equitable to increase or reduce cost
24 of service by tax costs or benefits that are not related to the rendition of utility service
25 to customers.
12 DIRECT TESTIMONY OF CYNTHIA S. PRIETO
629
1 Said another way, income taxes have no independentexistence of their own.
2 They are based on revenues and expenses. Once the Commission decides on the
3 appropriate reVenues and expenses that are necessary for the provision of electric
4 service, the related income taxes can be determined.
5
6 Q. WHAT IS THE AMOUNT OF FEDERAL INCOME TAX EXPENSE THE COMPANY
7 'IS REQUESTING TO BE INCLUDED IN RATES?
8 A. The Company is requesting the amount of federal income tax expense that is
9 included in cost of service reflected on Schedule G-7.8.
10
11 Q HAS THE COMPANY COMPUTED FEDERAL INCOME TAXES IN ACCORDANCE
12 WITH SECTIONS 36.059 AND 36.060 OF PURA?
13 A. Yes. PURA Sections 36.059 'and 36.060 address the treatment of certain tax
14 benefits; including ITC and consolidated tax savings. PURA Sections 36.059(b) and
15 36.060(c) specifically require a utility .that retains ITC to deduct it from the rate base
16 to which tlie credit applied, to the extent allowed by the IRC. The post-1970 portion
17 of unamortized ITC is not included as a r.eduction of rate base because. the Company.
18 is an "Option 2" company for ITC purposes. Under IRC Section 46(f), an "Option 2"
19 election requires that the post-1970 ITC be returned to customers as a reduction of
20 cost-of-service, rather than as a reduction of rate base.
21 Additionally, PURA Section 36.060(b) requires that income taxes related to
22 intercompany profits on affiliated purchases be applied tb reduce 'the cost of the
23 property or service purchased., The Comioany had no affiliates or subsidiaries for the
24 Test Year ended September 30, 2016, or during the Test Year. As a result, tax
25 expense included in this filing has been, calculated in accordance with PURA
26 Section 36.060(b).
13 DIRECT TESTIMONY OF CYNTHIA S. PRIETO
630
1
Further, PURA SeOtion 36.060(a) requires that income tax expense included
2
in cost of service reflect only expenses and investments- included in cost of service
3
and rate base. The Companys income tax amounts included in cost of service are
consistent with this provision.
5
6 VI. STATE INCOME TAXES
7 Q. WHAT IS THE AMOUNT OF STATE INCOME TAX EXPENSE THE COMPANY IS
8 REQUESTING TO BE INCLUDED IN RATES?
9 A. The Company is requesting the amount of state income tax expense that is included
10 in cost of service reflected on Schedule G-7.8.
11
12 Q. WHICH ACCOUNTING METHOD HAS EPE USED TO DETERMINE STATE
13 INCOME TAX EXPENSE IN THIS CASE?
14 A. Pursuant to the settlement agreement that was approved by the Commission Final
15 Order in the Company's last rate case, PUCT Docket No. 44941, the Company has
16 used the normalization method to determine the state income tax expense included
17 in cost of service.
18
19 Q. WHAt DID THE SETTLEMENT IN PUCT DOCKET NO. 44941 PROVIDE WITH
20 RESPECT TO STATE INCOME TAX EXPENSE?
21 A. Prior to, PUCT Docket No. 44941, the Company used the flow through method to
22 calculate state income tax' expense: However, in- PUCT Docket No. 44941, the
23 Company requested to switch to the normalization method. The settlement
24 approved in the case authorized the change in methodologies. Article I. Section F. of
25 the Settlement Agreement stated:
14 DIRECT TESTIMONY OF CYNTHIA S. PRIETO
631.
1
Beginning January 1, 2016, EPE should begin normalizing state income tax
2
expense. In other words, it should begin including both current and deferred
3
state income tax expenše in its revenue requirement (just as it- does for
4
federal incõme tax expense) instead of just the current portion of state
5
income tax expense. On that date, it should also begin amortizing the test
6
year-end balance of accumulated deferred state income tax expense that has
7
not yet been included in cost of service over a 15-year period.
8
This provision was. adopted in Findings of Fabt Nos. 40 and 60 in the Final Order
9 issued in PUCT Docket No. 44941.
10
11 Q. HAS THE COMPANY COMPLIED WITH THIS PROVISION?
12 A. Yes, it has. In August ,2016, after the Final Order was issued in PUCT Docket
13 No. 44941, the Company began normalizing state income tax expense and recorded
14 adjustments to make the change retroactive to January 1, 20161. In this filing it has
15 included both ci.Frent and deferred state income tax,expense in its state income tax
16 expense request. Further, the Company also began amortizing its balance of
1T accumulated deferred state income tax expense• that has not yet been included in
18 cost of service over a 15-year period.
19
20 Q. WHAT IS THE AMOUNT OF STATE INCOME TAX EXPENSE THE COMPANY IS
21 REQUESTING BE INCLUDED IN ITS COST OF SERVICE?
22 A. State income tax expense is shown on pages 3 to 5 of Schedule G-7.8. The annual
23 amortization of the January 1, 2016 balance of accumulated deferred state income
24 tax not yet included in cost of service is calculated on Schedule G-7.9(a), line 59,
Although the Final Order in PUCT DoCket No. 44941 was issued August 25, 2016, the Company's accounting treatment was"retroactive to January 1, 2016.

9 Q. DOES THIS SCHEDULE REFLECT THE IMPACTS OF BONUS DEPRECIATION?
10 A. Yes. The Company can and has claimed bonus depreciation as permitted by the
11 IRC. Depending on the year certain capital assets were placed in service, the
12 additions are eligible 'for 50 percent or 100 percent bonus depreciation. This
13 effectively means that for income tax purposes; in addition to tax depreciation
14 computed using the Modified Accelerated Cost Recovery System ("MACRS"), the
15 Company can claim an additional 50 percent or 100 percent of the eligible tax basis
16 as a tax depreciation deduction in the first year. As a result, EPEs Test Year end
17 ADIT related to these book/tax depreciation temporary differences has increased to
18 reflect the future tax liability associated with these accelerated deductions.

12 Q. PLEASE DESCRIBE SCHEDULE G-7.5; ANALYSIS OF ITCS.
13 A. This sthedule presents the analysis of the ITC adjustment for Deferred Investment
14 Tax Credit (DITC") to be included in cost of service. The Company's election under
15 Section 46(f)(2) of the IRC does not permit amortization of ITC to reduce income tax
16 expense in cost of service at a rate more rapidly than ratably — no faster than over
17 the book life-of the assets that generated the ITC. The "stripped" book depreciation
18 rate requested is derived from the book depreciation calculation reflecting , the life
19 extension of the Palo Verde Nuclear Generating Station ("PVNGS") unit where
20 applicable. This rate represents the life or investrnent portion of the book
21 depreciation rate without regard to amounts for cost of removal or salvage. The
22 stripped depreciation rate is multiplied by the ITC amortization base to calculate the
23 annual amount of DITC amortization included in cost of service. The stripped
24 depreciation rate is used in this computation to avoid a potential normalization
25 violation that could result if the ITCs were amortized in cost of service at a rate more
26' rapid than ratably. Workpaper G-7.5 shows the calculation of the Test Year ITC. For

21 DIRECT TESTIMONY OF CYNTHIA S. PRIETO
638
1 Q. DID THE COMPANY REFLECT AN ADJUSTMENT TO ITS TEST YEAR DPAD
2 AMOUNT ON SCHEDULE G-7.8?
3 A. Yes. Although the DPAD is generally a deduction for income tax purposes, the
4 federal income tax calculation for the Test Year has an adpition of $4 million related
5 to the DPAD on Schedule G-7.8, line 8, column (b). This situation arose due to the
6 enactment of the PATH Act in December 2015. In the third quarter of 2015, the
7 Company was projecting taxable income for 2015 and therefore was eligible- to
8 deduct the DPAD. Based on the projection of taxable income, the Company
9 recorded a deduction of $4 million for the DPAD in its tax accrual in the third quarter
10 of 2015. However, when the PATH Act was enacted in December 2015,. additional
11 tax depreciation. deductions for bonus depreciation resulted in a net operating loss
12 'for the Company for the tax year 2015. Because the Company did not have taxable
13 income, it was no longer eligible for the DPAD and reversed this 'deduction in the
14 December 2015 tax accrual. The tax accrual for the Test Year includes the fourth
15 quarter of 2015 and therefore includes the reversal of the DPAD in the amolint of
16 $4 million. The Companys requested income .tax calculation does not include a
17 reversal or deduction for the'DPAD because the requested dncome tax calculation
18 results in a net operating loss for the rate year and threfore the Company is not
19 eligible for the DPAD. As explained earlier, the net operating loss was due to tax
20 depreciation deductions from bonus depreciation.

2
further categorized as "protected" or "unprotected." Protected excess deferred taxes
3
refer to specific rate treatments in the IRC that dictate how these amounts of excess
4
deferred taxes should 'reverse. Violation of the rate treatment specified by the IRC is
5
a nórmalization violation which, as described previously, results in the loss of
6
favorable income tax treatment of certain tax deductions (such as accelerated
7
depreciation), requiring the payment of higher current federal income taxes than
8
would have been paid if the proper rate treatment were followed. Unprotected
9
excess deferred taxes have no such rate treatment required in the IRC.

18 property tax levied by as many as six or more jurisdictions.
19
20 Q. HOW ARE THE PROPERTY TAX AMOUNTS IMPOSED BY THE TAXING
21 JURISDICTIONS DETERMINED?
22 A. Property tax is typically assessed against the appraised or taxable valUe of the
23 Companys property located within the jurisdiction of a taxing authority. Generally,
24 the property tax appraisal process is a two-step process for a regulated utility. The
25 first step is to establish a market value for all of the utilitys property, collectively.
27 DIRECT TESTIMONY OF CYNTHIA S. PRIETO
644
1 This is referred to as a "unir valuation. The second step is to allocate that market
2 value of the unit to the taxing-jurisdictions in which the utility owns taXable proOerty.
3 Once the taxable value for a tax jUrisdiction is determined and final; the
4 jurisdiction calculates and sends a bill to the taxpayer. The billed amount' is
5 determ.ined by multiplying the' jurisdiction's tax rate by the taiable value of EPE's

18 REGULATORY AGENCY?
19 A. Yes. I have provided testimony before the Public Utility Commission of Texas (PUCT"
20 or "Commission") as well as the New Mexico Public Regulation Commission
21 (NMPRC").
22
23 II. PURPOSE OF 'TESTIMONY
24 Q. WHAT IS`THE PURPOSE OF YOUR TESTIMONY?
25 A. The purpose of my testimony i to present an overview of EPE's system operations
26 activities, such that EPE can meet its load serving responsibilities. I also describe
2 DIRECT TESTIMONY OF DAVID C. HAWKINS
656
1 the selecticin, regulatory approval; and the benefits of the two new generating units
2 added to EPE's fleet since EPE's rate case filed in 2015. Last, I also present EPE's
A

6 Q. WHAT EXHIBITS AND SCHEDULES DO YOU SPONSOR?
7 A. The exhibits that I sponsOr are identified in the Table of Contents of my testimony.
8 The schedüles that I sponsor or co7sponsor are identified in Exhibit DCH-1.
9
10 Q. - WERE THE SCHEDULES AND EXHIBITS THAT YOU SPONSOR 'OR
11 CO-SPONSOR PREPARED BY YOU OR UNDER YOUR SUPERVISION?
12 A. Yes, they were.
13
14 III. , SYSTEM OPERATIONS OVERVIEW
15 Q. PLEASE PROVIDE AN OVERVIEW OF EPE'S LOAD SERVING RESPONSIBILITIES.
16 A. From an operational standpoint, EPE monitors its resource and transmission system
17 to ensure that the system load obligations can be rnet on. a real time basis. This
18 means EPE's generation must prbvide dynamic response to system changes in load,
19 frequency, and voltage. In addition, EPE must have sufficient re'sources to meet
20 daily peak load and load profile requirements, as well as have sufficient reserves for
21 a resource or transmission contingency.
22 114.
23 Q. DOES EPE HAVE SIGNIFICANT LOAD SERVING RESPONSIBILITIES OUTSIDE
24 OF THE SUMMER PEAK PERIOD?
25 A. Yes. EPE is a summer peaking utility, so demand is "much higher in the sumrner
• 26 relative to .other times of the year. However the dynamic resrionse of resources to
3 DIRECT TESTIMONY OF DAVID C. HAWKINS
657
1 system reliability remains a 24 hour, year round obligation. As EPE witness
2 Andres R. Ramirez describes in his testimony, EPE's generation mix is composed of
3 base load, load following and peaking units which provide system operational
benefits during all seasons.
5
6 Q. HOW DO PEAKING GENERATION RESOURCES PROVIDE AN OPERATIONAL
7 BENEFIT OUTSIDE OF THE SUMMER MONTHS?
8 ' A. The term peak, or peak load, for long-term resource planning, typically refers to an
9 annual projected maximum hourly load usage. However, from an operational
10 perspective, every day has an hour in which there is a maximum daily energy usage,
11 which is the peak load of that day. Peaking resources can be used outside of the
12 summer months to meet each day's peak load requirements, particularly in the winter
13 months, as can be seen in the capacity factor characteristics in Schedule H-12.3a.
14
15 Q. WHY DO EPE'S PEAKING RESOURCES PROVIDE A PARTICULAR BENEFIT IN
16 THE WINTER MONTHS?
17 A. EPE'S peaking resources benefit EPE's system in the winter months and are
18 particularly useful during that season, in managing the impact of solar resources,
19 large scale and residential, on EPE's system. EPE's peak energy usage in the
20 winter months typically occurs in the evening. As the sun goes down, EPE loses
21 solar resource contributions to load and this loss is sequentially followed with an
22 increase in customer energy usage, which results in a relatively steep demand
23 increase. Peaking resources serve not only to replace the contribution from solar
24 generation, but to meet the additional energy usage of a typical winter evening. In
25 addition, in the pre-dawn morning hours prior to the solar resources contribution,
26 and as customer energy usage begins to climb, ,EPE has utilized peaking generation
4 DIRECT TESTIMONY OF DAVID C. HAWKINS
658
1 resources to meet increasing energy demand. As solar contribution increases as the
2 sun rises, EPE 'is Ale to reduce its peaking generation, primarily from its General
3 Electric LMS100 ("LMS100") generation units that EPE witness Ramirez describes,
4 due to their flexibility and dispatchability.
5
6 IN/. NEW EPE GENERATION FACILITIES
Q. WHAT IS THE PURPOSE OF THIS SECTION OF YOUR TESTIMONY?
• 8 A. The purpose of this section of my testirridny is to provide planning and regulatory
9 backgrCund information on the two new, natural gas-fired generation units for which
10 EPE seeks rate base treatment in thg case: the Montana Power Station ("MPS")
11 Units 3 and 4, which are nomin'ally rated at 89 MegaWatts ("MW") each. Specifically,
12 I presenta brief overview of the selection of the units and the proceedings in which
13 EPE obtained CCN approval. EPE witness Ramirez explains the technical
14 information about these new units and supports the prudence of their construction
15 costs.
16
17 Q. WERE MPS UNITS 3 AND 4 PART OF ONE SELECTION PkOCESS?
18 A. Yes, in fact MPS Units- 1 - 4 resulted from the same planning and selection process.
19 However, EPE deliyed requesting Certificate of Convenience and Necessity (CCN")
20 authorization for MPS Units 3 ahd 4 until a later date. Thus, they were subject to a
21 later proceedirt before the Commission than the CCN prbceeding for Units .1 and 2.
22 In simple terms, the process EPE followed to select the MPS Units began
23 with a determination that additional capacity resources were needed based on its
24 load forecasts and planning reserve margin criteria. Then EPE issued a request for
25 proposals ("RFP") to acquire those resources and was assisted by an independent
26 monitor or evaluator in analyzing the bid proposals. EPE then obtained CCN
5 DIRECT TESTIMONY OF DAVID C. HAWKINS
659'
1 approvals for the new generation projeds from both the Commission and the
2 NMPRC.
3
4 Q. HAVE EPE'S NEWEST GENERATION ADDITIONS SERVED TO BENEFIT THE _
5 OPERATION OF EPE'S SYSTEM?
6 A. Yes they have. As witness Ramirez addresses in his testimony, apart from Copper
7 Power Plaht, Rio Grande Power Plant Unit 9, and the MPS Units 1 through 4, EPE's
8 local generation fleet was originally designed for base-load generation. But now the
9 older local gas-fired generating units operate as intermediate or load following duty
10 units. These g6s-fired units were nOt meant for cycling during summer peak loads
11
and, therefore; that type of operation would ,increase wear and tear on the units,
12 shorten their lives, and have a negative impact on unit reliability. Gas turbines,
13 particularly Rio Grande Unit 9 and the MPS-Units which -are LMS100 units, can be.
14 cycled daily and have a faster response to system changes, and they have reduced '
15 the load following and Cycling impact on EPE's other gas-fired generation.
16 , Additionally, the LMS100 units are more efficient unifs as compared to EPE's -„
17 conventional stea' m turbines, as shown by comparison of their heat rates" in'
18 Schedule H-12.3a. As the LMS100 resources are dispatched, offsetting productiOn
19 from EPErs older and less efficient generators, fuel savings are incurred.
20 '
21 MPS Units 3 and 4
22 Q. DESCRIBE IN GENERAL THE PROCESS FOR SELECTING MPS UNITS 3 AND 4.
23 A. As I mentioned above, MPS Units 3 and 4 resulted from the same planning and RFP
24 process.
25 EPE's 2011 annual planning process indicated that EPE would need additional
26 peaking capacity beginning in 2014 and increasing thereafter. To meet this need for
6 , DIRECT TESTIMONY OF DAVID C. HAWKINS
660
1 additional resources, EPE issued an RFP ih June 2011, once again being assisted by
2 an independent evaluator to oversee the- process. After all the bid proposals were
3 analyzed, the optimal resource was a combination of two bids—a solar purchased
4 power agreement from a facility located in Luna County, New Mexico (Macho Springs),
and an EPE self-build proposal for four LMS100 units to be built in phases and located
6 east of the City of El Paso on a new power plant site—the MP."' These four neW
7 self-build units would be called MPS Units 1, 2, 3, and 4.
8
9 Q. YOU MENTIONED FOUR MPS GENERATION UNITS. WHICH OF THOSE FOUR
10 UNITS ARE WITHIN THE SCOPE OF THIS RATE CASE?
11 A. Only MPS Uriits 3•and 4 are within the scope' of this rate case. _These two units have
12 been conštructed and entered service within the Test Year, and as EPE' witness
13 ,Ramirez explains, those two. units are used and useful. MPS Units 1 and 2 had
14 already been construciad and were included in rates in EPE's last rate proceeding,
15 Docket No. 44941.
16
17 Q. DID EIDE Gb ON 21-0 SECURE THE SOLAR PURCHASER POWER PROPOSAL
18 FOR THE FACILITY IN LUNA COUNTY, NEW MEXICO?
19 A. Yes. This is the Macho Springs Solar Facility. EPE negotiated and signed a
20 long-term power purchase agreement. I discuss the cbnsideration of the capacity
21 value for planning purposes from that purchase in'the next section of my testimony.
22
23 Q. . AFTER THE BID PROPOSAL FOR THE MPS UNITS WAS SELECTED, DID EPE
24 SEEK CCN APPROVAL FOR MPS UNITS 3 AND 4?
25 A. Yes, but as I mentioned- above, approval for 'these two units was not sought
26 immediately after selection. The reason that the request for CCN authority for MPS
7 DIRECT TESTIMONY OF DAVID C. HAWKINS
661
Units 3 and 4 was delayed was that EPE.projected a need for MPS Units 1 and 2 in
2 the near future at the time, and the Company decided to limit its first request (Docket
3 No. 40301) to the first iwo units at the MPS site, in an effort to simplify the filing.
4 EPE did file for CCN approval of Units 1 and 2 in Texas in April 2012 in Docket
5 No. 40301. Ultimately, EPE and all the other parties to the case filed a settlement
6 recommending that the CCN'request be granted. In its December 2012 order, the,
7 PUCT amended EPE's CCN to include MPS Units 1 and 2.
8
9 Q. WHEN DID EPE SEEK AND OBTAIN CCN APPROVAL OF MPS UNITS 3 AND 4?
10 A. MPS Units 3 and 4 were presented in and received CCN approval in Docket
11 No. 41763, which was filed on September 6, 2013. The Final Order granting
12 approval was i'ssued July 11, 2014, and is attached as my Exhibit DCH-2. The case
13 itself was contested, but the. Commission found that the selection procesš (Finding of
14 Fact No. 24) and the sèlection itself were reasonable (Conclusions of Law Nos. 7
15 and 8).
16
17 Q. DID EPE RECEIVE CCN ApPROVAL FOR THE NEW GENERATION UNITS FROM
18 THE NEW MEXICO COMMISSION?
19 A. Yes, it did. EPE made CCN appro'val filings before both the Commission and the
20 NMPRC. Both Commissions issued the requested CCN approvals.
• 21
22 Q. ABOVE YOU MENTIONED THAT THE INTENDED BENEFITS OF THE NEW
23 GENERATION UNITS HAVE MATERIAEIZED. PLEASE SUMMARIZE THESE
24 BENEFITS TO EPE AND ITS CUSTOMERS.
25 A. EPE and its customers are benefitting from these neW generation projects in ways ,
26 the CCN proceedings intended.
8 DIRECT TESTINIONY OF DAVID C. HAWKINS
662
1 First, these units help EPE cóntinue to provide reliable service by, for
2 eiample, helping EPE h6e the resources to meet load growth, reserve margin
3 needs and provide local voltage support.
4 Second, these two new generation units-help to continue to modernize EPE's
5 aging local generation fleet. Table D6-1-1 below lists EPE's local generating units
6 based on in-service dáte from earliest to most recent. The,table illustrates that out of
7 1,444 MW of local genertion capability, EPE has seven generating units comprising
8 726 MW of net generating capacity With an average of 48 years in service. EPE's
9 most recent reserve margin, planning document. (the Loads & Resources' or L&R
10 document) shows that EPE does not anficipate retiring any .of the identified
11 generating assets until the end of 2022, (Rio Grande Unit 7, Newman Power Station
12 Units 1 and 2), at which times these generating •units will have 60+ years in service,
13 well beyond their original planned life of 50 years.

LMS100 uriits. operate as peaking and intermediate duty units. Moreover, unlike
2 EPE's older units, the LMS100 units can come on-line and be at, full load within ten
3 minutes and ,can be ramped up and down as needed: EPE's load 'can change
4 dramatically from day-to-day, and the LMS100 units will allow EPE to more efficiently
5 meet those fluctuations as well as help meet its daily peak demands. In contrast,
6 EPE's older generation unitS are not capable of performing this type of operation in
7 nearly as efficient a manner.
8
9 Q. ARE THE NEW MPS UNITS USED AND USEFUL?
10 A. Yes. Schedule H-12.3a shows during the t'ate year the extent at which MPS Units 1,
11 2, and 3 were relied on, as indicated by their respected capacity factors. In
12 particular, since their commercial operation dates, MPS Unit 3, which had an
13 average capacity factor of 44%, and MPS Unit 4 with a capacity factor of 46% have
14 both been used and useful. Although MPS 4 became commercial in September
15 2016, it is expected to be utilized in a similar manner as that of MI7S Units 1 through
16 3. The MPS Units are used.and useful.
17
18 V. IMPUTED CAPACITY
19 Q. IS EPE SEEKING TO INCLUDE PURCHASED POWER CAPACITY -COSTS IN
20 EPE'S COST OF ŠERVICE?
21 A. Yes. EPE is seeking to include capacity costs associated with two renewable energy
22 Purchased Power Agreements ("Solar PI5As") used to serve Texas customers. The •
23 first Solar PPA is * the Macho Springs 50 MW solar agreement which began
24 commercial operation in May 2014. The second Solar PPA is the Newmen 10 MW
25 solar agreement, whiCh began in December 2014. I develop the imputed capacity

1 costs associated with these contracts and EPE witness Jennifer I. Borden sponsors
2 the adjustment to reflect the revised costs ihcost of service.
3
4 Q. DO THE SOLAR PPAs INCLUDE SPECIFIED CAPACITY CHARGES?
5 A. No, they do not: However, in a past fuel reconciliation, PUCT Docket No. 41852,
6 which is the fuel reconciliation previous to the currently pending one, EPE imputed a
7 capacity charge associated with an energy-only PPA that served to meet EPE's
8 planning reserve criterion. Then, in bóth EPE's last rate case proceeding, Docket
9 No. 44941, and in the pending ,fuel, reconciliation, Docket No. 46308, EPE irnputed
10 capacity to both of these solar agreements I mention above. The Solar PPAs are
11 accounted for in EPE's Loads and Resources ("L&R") document, which s used to
12 calculate' EPE's planning reseeve margin.
13
14 Q. ARE THERE OTHER PPAs INCLUDED IN EPE'S CURRENT L&R WHICH
15 CONTRIBUTE TO EPE'S PLANNING RESERVE MARGIN?
16 A. Yes. Although these contracts are similar to the Solar PPAs in that they are included
17 in EPE's L&R, are renewablë, and are energy-only contracts, EPE is not seeking to
18 impute associated capacity charges to include in its Texas jurisdictional c9st of
19 service. EPE •included the full contract charges for these remaining PPAs without
20 dispute in PUCT Docket No. 41852 ahd are allocatetho the New Mexico judidiction,
21 as they were procured under the New Mexico Renewable Portfolio Standard. All of
22 the costs for these contracts are recoveredirom New Mexico customers through the
23 New Mexico fuel rebovery charge.
24
25 Q. WHAT IS THE IMPUTED CAPACITY AMOUNT FROM THE SOLAR ,PPAs EPE IS
26 SEEKING TO INCLUDE IN ITS COST OF,SERVICE?
12 DI'IRECT TESTIMONY OF DAVID C. HAWKINS
666 r
A. EPE is proposing the same methodology used in Docket No. 44941, however, EPE
2
is now using Test Year operational data, and EPE's current Federal Energy
3
Regulatory Cdmmission ("FERC") approved Open Access Transmission Tariff
4
("OATr) language td calculate the imputed capacity charge. The methodology to
5
calculatè the imputed capacity charge was previously based on the'projected energy
6
productiOn of the two solar projects 6ecause their Oommercial operation dates
7
occurred within the Test Year in Docket No. 44941. EPE is seeking to include a
8
capacity charge of $2.35/kW/Month for the Macho Springs PPA and a charge of
9
$2.33/kW/Month for the Newman PPA. These charges are based on the .WSPP
10 (formerly known aš Western Systems Power Pool) Agreement capacity rate of
11 $7.32/kW/Month, with adjustments made based on the intermittency of these two
12 resources.
13
14 Q. IS THIS THE SAME CAPACITY CHARGE THAT EPE USED FOR IMPUTED
15 CAPACITY FOR THESEIWO CONTRACT§ IN DOCKET NOS. 44941 AND 46308?
16 A. No. The imputed capacity charge is currently $2.05/kWMonth for the Macho Springs
17. PPA and $1.91/kW/Month for Newman PPA in Docket Nos. 44941 and 46308. If a
18 higher imputed capacity charge is approved in this case, the change will
19 proportionally reduce the associated energy thsts reflected in fuel and purchased
20 power expenses recovered through the Texas Fixed Fuel Factor once the new
21 imputed capacity charges go into effect. A
22
23 Q. HAS EPE RELIED ON A DIFFERENT METHODOLOGY THAN THAT USED IN
24 DOCKET NOS. 44941 AND 46308 TO CALCULATE THE IMPUTED CAPACITY
25 CHARGE?
13 DIRECT TESTIMONY OF DAVID C. HAWKINS
667
1 A. Only to the extent that actual energy production data was used-instead of projected
2 data., While Docket No. 46308, the fuel reconciliation, is still pending, in Docket
3 No. 4494'1, no party challenged the-imputed capacity or the calculation methodology
4 EPE presented in the rate proceeding. The case was settled, however, without a
5 finding expressly addressing the imputed 'capacity charge.
6
7 Q. DID EPE REFERENCE A DIFFERENT CAPACITY CHARGE WHEN IMPUTING A
8 CAPACITY CHARGE IN PUCT DOCKET NO. 41852?
9 A. Yes, EPE Lised .an imputed capacity rate cif $7.56/kW/Month in PUCT Docket
10 No. 41852 for'a then existing PPA with ŠPS. This rate was based on SPS's
11 FERC-accepted cost of service rates, as reflected in Service Schedule Q of the
12 WSPP Agreernent. The two-providers associated with the Solar PPAs do not have
13 FERC-accepted cost of service capacity rates. As such, after EPE reviewed the
14 WSPP Agreement Service Schedule C, which is the service schedule for firm
15 capacity and energy transactions, EPE capped the capacity charge at
16 $7.32/kW/Month, -which is the general tapped capacity chkge under" the WSPP
17- Agreement that pplies to suppliers who do not' have a specific FERC approved
18 capacity rate.
19
20 Q. WHY bOES EPE REFER TO THE WSPP AGREEMENT WHEN DETERMINING AN
21 IMPUTED CAPACITY CHARGE?
22 A. In EPE's fuel reconciliation in PUCT Docket No. 26194, the Commission imputed a
23 capacity charge to a PPA that * had no explicit. capacity charge. The Commission
24 determined the WSPP price cap is reasonable and should be used for that purpose.
25
14-, DIRECT TESTIMONY OF DAVID C. HAWKINS
668 •
1 Q. IF THE COMMIS'SION DEtERMINED THAT THE WSPP PRICE CAP IS
2 REi?kSONABLE, WHY IS EPE IMPUTING A CAPACITY CHAR6E AT A LESSER
3 RATE?
4 A. The rates used by EPE in previous PUCT Dockets were associated with PPAs
5 having firm energy. By the very nature of the Solar PPAs, the output from •these
6 resources is intermittent. I am not aWare of the Commission having addressed the
7 methodology, or even a requirement, to impute capacity to a resource that is _
8 intermittent in its output. As such, EPE is using a lower imputed capacity charge to
9 reflect the appropriate level of dependable output that EPE can' rely on to meet its
10 jurisdictional load requirements. Additionally, the providers for each PPA have no
11 obligation to produce energy to meet EPE's peak load requirements. The obligations
12 of the providers are limited to an annual minimum total energy output, so
13 consequently the capacity associated with these renewable PPAs is of much lower
14 value.
15
16 Q. WHY WOULD EPE NOT USE AN IMPUTED CAPACITY CHARGE THAT
17 CORRELATES TO THE E?(PECTED RESOURCE OUTPUT USED IN ITS L&R?
18 A. EPE used an expected capacity factor of 70 percent for solar resources in,its L&R.
19 This value is approximate to butpLit verified by EPE over its peak load hour.
20 However, this capacity factor is representative of a solar facilitys output at one
21 specific hour of the year. There are other periods of the year in which EPE's monthly
22 peak load occurs at night and the output from solar facilities produce 0 MW. The Se
23 Solar PPAs are long-term agreements,, and the capacity associated with these
24 agreements is not comparable to a summer-only PPA or any firm energy agreement.'
25 , Intermittent generation requires additional ancillary services to maintain a
26 stable electric grid. These ancillary services include regulation and operating and
15 DIRECT TESTIMONY C* DAVID C. HAWKINS
669
supplemental reserves that should be deducted from any imputed . capacity value.-
2 For these reasons, the imputed capacity charge does not correlate to the expected
3 capacity factor.
4
5 Q. HOW Dlp EPE CALCULATE THE IMPpTED CAPACITY RATES FOR THE SOLAR-
6 PPAs?
A. EPE adjusted the imputed capacity charges to reflect the additional ancillary services
8 attributable to an intermittent resource. This adjustment is based on the
9 FERC-accepted ancillary service rates within EPE's OATT. Additionally, EPE made
10 adjustments to reflect the Test Year energy output associated with the Solar PPAs.
11
12 Q. WHAT WAS THE IMPUTED CAPACITY CHARGE AFTER ADJUSTING FOR
13 ANCILLARY SERVICE REQUIREMENTS?
14 A. The imputed capacity Charge .w'es $7.20/kW/Month after adjusting for the associated -
15 ancillary service schedules found in EPE's OATT. The applicable schedules are
16 Schedule 3 (Regulation and Frequency Response), Schedule 5 (Operating
17, Reserve-Spinning Reserve Service), and Schedule 6 (Operating
18 Reserve-Supplemental Reserve Service). The rate for each of these schedules is
19 $3.10/kW/Month. Schedule 3 requires 0.87 -percent of rated MW obligation, and
20 'Schedules 5 and 6 each requires 1.5 percent of rated MW obligation. Adjusting the
21 WSPP rate of $7.32/kW/Month, by the Combined Schedules 3, 5, and 6 obligations of
22 3.87 percent (i.e., -0.87% .+ 1.50% + 1.50%), multiplied by the rate of
23 $3.10/kW/month, the "net capacity rate" is $7.20/kW/Month (i.e., $7.32/kW/Month —
24 (.0387 X 3.10/0WMonth)).
25
16 DIRECT TESTIMONY OF DAVID C. HAWKINS
670
1 Q. WHAT WERE THE FINAL IMPUTED CAPACITY CHARGES AFTER ADJUSTING
2 FOR THE ENERGY PRODUCTION OUTPUT?
3 A. EPE based the energy production.output component of the imputed 'capacity charge
4 on actual Test Year production. Macho Springs had a 32.6 percent energy
5 production output level, and Newman Solar had a 32.3 percent energy production
6 output. The final imputed capacity charges are the products of the "net capacity
7 rate".and the Test Year energy Output percentages. The resulting imputed capacity
8 charges are'$2.35/kW/Month for the Macho Springs PPA, and $2.33/kW/Month for
9 the Newman Solar PPA. EPE witness Borden adjusts the revenue requirements ,for
10 the total dollar amount in imputed capacity charges for each facility.
11
12 Q. DO YOU BELIEVE THIS IS A• PRUDENT VALUATION OF THE 'CAPACITY
13 COMPONENT OF THE SOLAR PPAs?
14 A. Yes, I do. Renewable resources such as those in the Solar PPAs require EPE's
15 local generation to resPond to the intermittency of such resources. Although energy
16 is expected from the Solar PPAs during the summer peak load hours, the output
17 from Solar PPAs is weather dependent and not guaranteed (for example, a storm in
. 18 Deming, New`Mexico, will -reduce the output of the Macho Springs facility, while
19 El Paso may be experiencing clear skies and a temperature of 100 degrees). The ,
20 primary value from the Solar PPAs is from the 'fuel that iS saved while these
21 resources are producing energy, not from capacity that can be utilized to respond to f
22 system contingencies. Therefore, I believe the imputed capacity charges as
23 determined recognize the Solar PPAs contribution to EPE's planning reserves, while
24 at the same time recognizing these resources are primarily energy resources given
25 their intermittency and contribution to serving loads throughout all hours Of the year.

e-l.Geir • APPLICATIoN OF EL PASO § PUBLIC UTILITY COMMISSION ELECTRIC COMPANY TO AMEND ITS § CERTIFICATE OF CONVENIENCE § OF TEXAS AND NECESSITY FOR TWCO ADDITIONAL GENERATING UNITS § AT THE MONTANA POWER STATION § IN EL PASO COUNTY
ORDER
This Order addresses the application of El Paso Electric Company to amenkl its certificate
of convenience and necessity for two additional generating units at the Montana power station in
El Paso County. On June 5, 2014, the administrative law itidge at the State Office of
Administrative Hearings issued a proposal for decision finding that EPE established a need for
additional "capacity and recommending that the Public Utility Commission of Texas approve the
appliCation. The CoMmission agrees that the utility met its burden ti) establish need and that the
application should be Oproved. The Commission adopts the following findings of fact ind
conclusions of law:
I. Finding; of Fact
Procedural History
1. El Paso Electric (EPE) is an investor-owned electric utility providing retail electric
service in Texas under certificate of convenience and necessity (CCN) No. 30050.
2. On September 6, 2013, EPE filed with the Commission an application for CCN
authorization to build and operate-two additional 88 megawatt (MW) natural gas-fired
generating units, Montana units 3 and 4. The site for the proposed units is the Montana
power.station, in EPE's service area in eastern El Paso County, just east of the city of El
Paso.
12. 675
Exhibit DCH-2 Page 2 of 13
MC Docket NO. 41763 Order Page 2 of 13 SOAR Docket No. 473-14-1419
3. EPE published notice of the application on September 13, 2013 in the El Paso Times, a
newspaper having general circulation in EPE's Texas jurisdictional service territory.
4. On September 6, 2013, EPE delivered direct notice of the application to the city 'of
El Paso and the county of El Paso and mailed notice of the filing to all parties in EPE's
most recent base rate case, Application of El Paso Electric Company to Change Rates
and to Reconcile Fuel Costs, Docket No. 40094 (May 23, 2012).
5. On September 6, 2013, EPE mailed a complete copy of the filing, including the
environmental assessment studies (minus some of ihe appendices of one of the studies) to
the Texas Parks and Wildlife Department (TPWD). On September 24, 2013, EPE mailed
a complete copy of all three environmental assessrnents (including all the appendices) to
TPWD.
6. On September 25, 2013, EPE filed proof that, notice of this proceeding had been
provided.
7. The city of El Paso, Texas Industrial Energy Consumers, Rockney Bacchus, the Far East
El Paso Citizens United, and the county of El Paso filed requests to intervene and were
granted intervener status in this matter.
8. The Far East El Paso Citizens United and the county of El Paso requested to withdraw
their interventions, and the requestSvere granted.
9. TPWD did not seek intervention in this docket. TPWD filed comments in this docket on
October 30, 2013, but the comments were not offered or admitted into evidence.
10. On December 17, 2013, the Commission referred this docket to the State Office of
Administrative Hearings (SOAH) for assignment of an administrative law judge to
conduct a hearing and issue a proposal for decision, if necessary.
11. On January 9, 2014, the Commission isaued the preliminary order in this matter. The
- preliminary order identified the issues to be addressed by SOAH.
12. The hearing on the merits was held on February 19, 20, and 21, 2014.
13. The record closed on April 15, 2014, with the filing of reply briefs.

BackEround on EPE
14. EPE serVes retail customers in Texas and New Mexico, where it is subject to the
jurisdiction of the New Mexico Public Regulation Commission.
15. Retail competition has not been implemented in EPE's service area., As a result, EPE
contiiiues to provide bundled, regulated service to its Texas customers.
16. EPE's 2011 annual planning process indicated that, based on its load forecasts, expected
generating unit retirements, and reserve margin criteria; EPE would need additional
peaking capacity beginning in 2014 and would be faced with an increasing need for
capacity thereafter.
17. To meet this need for additional resources, EPE issued a request for proposals (RFP) in
June 2011, seeking 80 to 100 MW in 2014., 80 to 100 MW in 2015, and 160 to 200 MW
in 2016.
18. EPE retained Wayne Oliver, of the Merrimack Energy Group, Inc., as independent
evaluator to oversee EPE's RFP process by monitoring the bid evaluation and selection
process.
19. In response to its RFO, EPE i-eceived 38 proposals from 23 different companies.
20. Of the 38 proposals, five were solar-powered, 19 were gas-fired, four were wind-N.' wered
and 10 were demand-side or used power-storage technology.
21. EPE's generation projects group submitted eight self-build options.
22. EPE, during the RFP process, treated the. generation projects group as a different entity
• and did not communicate with them.
23. EPE and Mr. OliVer evaluated the bids and detennined that the optimal resource was a
combination of two bids—a solar purchased power agreement and one of EPE's self-
build propoials.
24. The RFP process that EPE undertook was reasonable.
25. - The EPE self-build proposal consisted of four General Electric (GE) LMS100 units to be
built in phases alid located east of the city of El Paso. on a new power plant site, the
Montana power station.

26. EPE ieceived CCN authorization for the first twO of these four Montana units—Montana ,
units 1 and 2—in December 2612 in:Application of El Paso Electrie Company to Amend
'Its Certificate of Convenience and Necessity for Generating units Montana 1 and 2 at the
Montana Site in Texas, Docket No. 40301 (Dec. 13, 2012).
27. Montana units 3 and 4 are expected to be added in 2016 and 2017, respectively.
28. EPE's recent 2013 load forecast continues to confirm-the need for Montana units 3 and 4.
Description of Montana Units 3 and 4
29. Montana units 3 and 4 will each consist of a GE LMS100 simple-cycle, aern-derivative
combustion turbine that will be fueled by natural gas, with the capability to burn fu61 oil
as their secondary fiiel source.
30. Montana units 3 ande4 will be the same size as, use the same technology as, and will be
built at the same site as Montana units 1 and 2.
31. The relatively high elevation (approximately 4,020) and high temperatures in the area
will affect the performance of the units, compared to their Performance if located at sea
level and under other International Organization for Standardization (ISO) site reference
Cmiditions (which are sea level elevatidn, temperature of 59 degrees Fahrenheit and 60%
relative humidity). Thus, although it would have a nameplate rating of 103 MW at ISO
conditions, each unit will deliver 88 MW het to EPE under summer peak conditions.
32. The high elevation in the area also means that the units heat rate' will be higher than it
would be at'ISO conditions.
33. The units' guaranteed full load heat rate is 9,074 British thermal units per kilowatt-hour,
with a themial efficiency ranging from 44% to 50%.
34. The units' relatively low heat rate compared to -the average heat rate of EPE's other
gas-fired generating tinits will result in fuel savings for EPE's customers.
35. The units will be used for peaking service and also intermediate serviCe and are expected
to operate at approximately a 40% capacity factor.
36. The units will be quick start units because they can be brought on-line within three
minutes and reach full load within 10 minutes.
678
Exhibit DCH-2 Page 5 of 13
MC Docket No. 41763 Order Page 5 of 13 SOAH Docket No. 473-14-1419
37. There is no limit on the units number of starts or on its minimum off-line or on-line time.
38. 'The units can be ramped up and down as needed (for example, they can be shut down
during off-peak hours) without negatively impacting maintenance costs.
39. Evaporative coolers will be used to cool the combustion turbine—inlet air for maximum
operating efficiency.
40. No other existing EPE operating generation unit (except Rio 'Grande unit 9, an LMS100
generating unit) has this combination of features.
41. EPE's system will also benefit from4the Units by the additional voltage support, an
additional type of contingency reserves, and additional flexibility in scheduling
maintenance outages.
42. Montana units 3 and 4 are expected to be operational by the summer peaks of 2016 and
2017, respectively.
43. , No other utility is or will be directly served by or connected to the proposed facilities or
involved in their construction.
44. The total estimated cash capital cost of the units is $151.2 million.
45. The estimated amount of allowance for fimds used during construction is $17.9 million,
for an overall estimated total cost of $169.1 million.
Stanitorv CCN Factors Adequacy of F41stine Service/Need for Additional Service
46. For reliability reasons, EPE needs the additional 'resources that .Montana units 3 and 4
will provide, and EPE's system will benefit from the units' operational features.
47. Through its 2011 RFP process, EPE prOperly considered and rejected alternatives to
Montana units 3 and 4.
48. As a member of the Western Electricity Coordinating Council (WECC), EPE maintains a
15% annual reserve margin, an amount of firm supply-side resources in excess of its firm
demand.
49: Although WECC does not require utilities to maintain a specific annual margin level,
EPE's 15% annual reserve margin is reasonable considering EPE's location on the grid.
679
Exhibit DCH-2 Page 6 of 13
PUC Docket No. 41763 Order Page 6 of 13 SOAH Docket No. 473-14-1419
50. EPE will hal'ie a capacity deficit starting in 2016. In 2018, the' deficit will grow to an
amount greater than the 176' MW output from Montana units 3 and 4, which EPE
proposes to build in_this proceeding.
51. EPE's need for additional capacity cannot be. significantly addressed by delaying the
retirement of Four Corners units 4 and 5 and Rio Grande unit 6.
52. EPE's need for additional capacity - cannot be significantly resolved by importing
purchased power because EPE's remote transmission system is being used to the
maximum extent feasible.
53. EPE's need, for additional capacity is greater than the amount of interruptible capacity on
its system.
54. EPE cannot replace its need for capacity solely with renewable resources.
55. Expanded energy efficiency programs could not meet EPE's projected need for peaking
and intermediate capacity.
The Effect of Grantine the CCN on EPE and Any Electric Utility SerYinzthe ProxintoteArea
56. There will be a two-fold effect on EPE in granting the CCN authorization for Montana
units 3 and 4—financial and operational.
57. The financial impact on EPE of Montana units 3 and 4 will be minimal. The construction
costs will be financed with cash geherated from operations or debt or a combination of
the two.
58. The financing will not impair EPE's ability to attract additional capital on reasonable
terms and at reasonable prices.
59. Operationally, the effect on EPE of granting the CCN willbe positive.
60. Montana uniis 3 and 4 will enhance EPE's ability to provide reliable service, since the
generating units are needed to meet customers' demand and EPE's reserve margin
criteria.
680
Exhibit DCH-2 Page 7 of 13
PUC Docket No. 41763 Order Page 7 of 13 SOAH Docket No'. 473-14-1419
61. The effect will also be positive from a systeni and transmission perspective. With the
addition orlocal generation in Montana units 3 and 4,:EPE will receive flexibility in
scheduling maintenance outages and voltage support in the local system.
62. Montana units 3 and 4 will provide voltage support in EPE's local system, an additional
type of contingency reserves, and additional flexibility in scheduling maintenance
outages.
63. Montana units 3 and 4 will not be located in the certificated service area of any other
utility.
64. There will be no adverse effects on any other electric Utility.:
Community Values
65. When EPE selected the Montana power station site, it was undeveloped, open -desert
scrubland, which people have used as a dumping gound.
66. The Montana site is surrounded by a mixture of different developments: indukrial
(Magellan fuel farm), commercial (mostly automotive salvage yards), military
development (U.S. Anny—Fort Bliss), but with very little residential development.
67. The Montana site is bounded on the north by Fort Bliss. An indukrial facility, the
Magellan oil storage/transfer facility is located adjacent, to the south of the proposed
Montana units 1 and 2. The southernmost portion of the site' is bounded by Montana
Avenue (State Highway 62/180).
68. There are go ,Tesidents on-site, and no signifiCant populations are anticipated in the near
future.
69. There is some residential development near the western boundarY of the Montana site,
where residential areas are located approximately one quarter of a mile to the west of the
units.
70. By the time they are constructed, Möntana units 3 and 4 will be. located on an existing
Power plant site.
71. The location of the units iS approximately 1,200 feet from the nearest residential
structures.
•-;

Exhibit DCH-2 Page 8 of 13
PVC Docket No. 41763 Order Page 8 of 13 SOAR Docket No. 473-14-1419
72. Existing development in the area will be minimally affected by the addition of the units.
73. While the Montana units -3 and 4 will create an incremental amount of noise, they are not
likely to significantly impact the closest noise receiver.
74. The units and associated access route are located in a rural area of El Paso County.
Residences in the area are sparse and are located on large lots (gieater than 0.75 acres),
and the residential structures are some distance (1,200 feet or more) from the proposed
units.
75. During construction, noise levels may increase, but this activity will be only temporary.
Additionally, the new units are not expected to operate continuously.
76. The units employ newer technology, and the design incorporates sound reduction features
to protect workers. These aspects result in less noise at the site bnundaries.
77. To a large extent, the incremental noise produced by the construction and operation of the
units will likely 'not stand out given the existing background noise from the existing
development, including roads, in this area.
78. The effect on community values will be minimal.
Recreational and Park Areas
79. There are no parks or recreational areas within one-half mile of the units. -
80. Because there are no recreational or park areas in proximity to the proposed units, there
will be no adverse effect on any recreational or park areas.
Historical and Aesthetic Values
81. By the time they are constructed, Montana units 3 and 4 will be located on an existing
power plant site.
82. The site of the units is an undeveloped desert scrubland.
83. No areas listed on the National Register of Historic places in Texas are located in
proximity to the units.
84. Any effect -on historical or aesthetic values will be minimal.

Environmental Integrity
85. By the time they are constructed, Montana units 3 and 4 will be located on an existing
power plant site.
86. The Montana Units 3 and 4 fall under the jurisdiction of the Texas Commission on
Environmental Quality (TCEQ); and the U.S. Environmental .Protection Agency (EPA)
has authority over some of the permitting aspects.
87. Various types of environmental ilerrnits, including air quality permits, must be obtained
from the TCEQ or EPA.
88. The environmental permitting regime, to which the units are 'and will be subject, along
with EPE's compliance with those permits, will help ensure the environmental integrity
of the surrounding area.
89. The units design will reduce the area of influence of potential environmental impacts
from emissions. In addition, mandatory compliance with the environmental components
of •those permits issued by state and federal agencies will help ensure that the
environmental integrity of the surrounding area is retained.
90. Montana units 3 and 4 will be equipped with emissions technology that is considered best
available control technology.
91. The city *Of El Paso Water Utilities/Public Service Board has agreed to provide water for
the units.
92. Montana units 3 and 4 are expected to have at most a minimal impiact on the
environmental integrity of the area.
Probable Imarovement of Service or Lowerini of Cost to Consumers itt Area if CCN is Granted
93. The capacity that will be proVided by Montana units 3 and 4 will improve electric service
because of the reliability and operational flexibility they will add to EPEs system, their
relatively lower heat rate within EPE's system, and their contribution to meeting EPE's
reserve margin needs.

= 94. In addition, EPE's transinission system will benefit because the new units can be 'started
to provide voltage support for the eastern Tart of the EPE high-voltage system during
normal conditions or during transmission outages.
95. A PROMOD operating simulation tO calculate the impact of Montana units 3 and 4 on
annual fuel cbsts estimated that fuel ciists would decline approximately $2.3 million in
the first ftill year of Operation for both units.
96. EPE predicted that the cost irnpact of the new generation units, considering the
combination of both base rates and fuel, would be $1.77 or a 2.41% increase in rates for
an average Texas residential customer using 600 lcilowatt-hours per month, for the first
year of operation.
To Extent Applicable, Effect of Grantinz CCN on Abiliti of this State to Meet PURA Goal for Addinz Renewable Energy Resources in § 39.904(a)
97. This statutory factor is not directly applicable because this- application does nen include
renewable generating facilities. ,
98. Becausé of the ability of the GE LMS100 units to ramp up and down easily, however, the
addition of Montana units 3 and 4 to EPE's fleet will accommodate the addition of
renewable energy resources.
Whether CCN Is Neceisary fot Service, Accommodation, Convenience, or Safetv of the Public under PURA 37.056
99. Considering all the above factors, EPE's requested CCN authorization to construct, own
and oPerate Montana units 3 and 4 is necessary for the service, accommodation,
convenience or safety of the public.
Effect ofCCN on Implementation of Customer Choice
100. Cnstonier choice has bben delayed in EPE's Texas service area.
101. Under Public Utility Regulatory Act (PURA), Texas Utilities Code §§ 11.001-66617, and
• § 39.553 and P.U.C: SUBST: R. 25.421, the timeline for implementation of retail
compefition in EPE's service territory is dependent upon completion of a five-stage
process; the first of which is development, approval and operation of a regional
transmission organization (RTO) for _the EPE region.
Exhibit DCH-2 Page 11 of 13
PUC Docket No. 41763 Order Page 11 of 13 SOAH Docket No. 47344-1419
102. No plan is in place to Ron or request FERC approval of an RTO, and EPE cannot
unilaterally form an RTO.
103. Approval of a CCN for the proposed generating units will not affect the development of
an RTO in which EPE could participate.
104. The approval of this CCN will also not affect any subsequent stage toward full retail
competition in EPE's service area.
11. Contlusions of Law
1. EPE is an electric utility as defined in § 31.002 of PURA.
2. The Commission has jurisdiction over the application pursuant to PURA §§ 14.001,
14.002, 37.051, 37.053, and 37.056.

1 A. Yes, it does. Rio Grande Unit 6 entered inactive reserve status on November 17,
2 2015; -it is no longer considered available capacity for planning reserve rnargin
3 purposes. However, Rio Grande Unit 6 was temporarily reactivated during the 2016
4 summer peak period due to systern constraints.
5
6 Q. IS THE COMPANY SEEKING TO RECOVER ANY COSTS ASSOCIATED WITH
7 THE RIO GRANDE UNIT 6?
8 A. No. As EPE witness Jennifer I. Borden describes, EPE,is not seeking to include any
9 Rio Grande'Unit 6 costs in rate base or in cost of service.
10
11 Q. DID EPE ADD ANY NEW GENERATION UNITS FROM. MARCH 31, 2015 (THE
12 END 6F THE TEST YEAR IN EPE'S LAST BASE RATE CASE IN DOCKET
13 NO. 44941) THROUGH, SEPTEMBER 30,.2016 (THE END' OF THE TEST YEAR IN
14 THIS DOCKET)?
15 A. Yes, as I mentioned above, EPE added two new generation units at the- MPS. MPS,
16 Unit 3 entered service on May 4, 2016,. and MPS Unit' 4 entered service on
17 September 15, 2016. MPS Units 3 and 4 are:gas-fired, nominally rated 89 MW
18 General Electric LMS100 simple cycle aero derivative combustion turbines that
19 provide peaking and load following capability, just like MPS Units 1 and' 2. MPS
20 Units.3 and 4 are included in the generation Table ARR-1 above. .
21,
22 Q. DtD EPE DIVEST ITSELF OF ANY GENERATION UNITS SINCE ITS LAST BASE,
23 RATE CASE?
24 A. Yes, it did. For decades EPE had been a minority owner of Units 4 and 5 of the coal-
25 fired Four Corners Power Plant located in northwestern New Mexico. EPE's interest
26 equated to 108 MW. In July 2016, when the controlling project agreements Were
6 DIRECT TESTIMONY OF ANDRES R. RAMIREZ,
696
1 scheduled to expire, EPE sold all of its ownership interest in Units 4 and 5. and
2 common facilities. As a result, Four Corners is excluded from the generation
3 Table.ARR-1 above.
4
5 Q. IS THE COMPANY SEEKING TO INCLUDE FOUR CORNERS IN BASE RATES?
6 A. lt is my understanding that EPE is not seeking to include any Four Corners'
7 investment and operating expenses in base rates. EPE witnesses James Schichtl
8 and Russell G. Gibson explain EPE's Four Corners rate proposal in their testimony.
9
10. IV. EPE'S LOCAL GENERATION FLEET—CAPITAL ADDITIONS
11 Q. WHAT IS THE PURPOSE OF THIS SECTION OF YOUR TESTIMONY?
12 A. The'purpose of this section of my testimony is to describe and support cost recovery
13 •of the capital additions to EPE's local generation fleet that EPE requests in this case.
14 The scope , of thiš request is those capital additions placed in service from.April 1,
15 2015,• through the Test Year 6nding September 30, 2016. First; I will address the
16 two most significant additions, which are MPS Units 3 and 4. With the completion of
17 these two units, EPE no longer has any generating 'units under construction. Then I.
18 will address the other capital additions.
19
20 Q. IS THERE A LIST OF THE MAJOR PRODUCTION PLANT CAPITAL ADDITIONS
21 TO THE LOCAL GENERATION FLEET THAT EPE SEEKS TO INCLUDE IN RATE
22 BASE?
23 A. Yes, EPE witness Larry J. Hancock includes a list of all plant additions that EPE has
24 made from April 2015 through September 2016 for local generation. The local
25 generation capital additions fall under the "Stearn & Other Production" category in•his-
26 exhibit. I sponsor the reasonableness of the coristruction expenditures.

697
1
2 A. MPS Units 3 and 4
3 Q. DO MPS UNITS 3 AND 4 MARK THE COMPLETION OF RECENT SIGNIFICANT
4 ADDITIONS TO EPE'S LOCAL GENERATION FLEET?
5 A. Yes, they do. Beginning in 2009 and ,continuing through September 2016, EPE
6 added six new generation units to its local fleet. These new units are: Newman
7 Unit 5 (Phases I and II); Rio Grande Unit 9; and NIPS Units 1, 2, 3, and 4. Pie total
8 capacity of all these units is 720 MW. The addition of these new generation units is
9 consistent with the plans outlined in the.filings for and approval of CCNs for. all of
10 these units. No additional generating units are currently under construction or the
11 subject of a CCN request.
12 Newman Unit 5, Rio Grande Unit 9, and MPS Units 1 and 2 have already
13 been included in rate base. In this current rate proceeding,. EPE is requesting that
14 the last two new generation units (MPS Units 3- and 4) be included in rate base. I
15 support the reasonabléness and prudence of the costs of these two units and show
16 that they are used and useful in serving EPE's customers. EPE witness Hancock
17 addresses the Company's Allowance for Funds Used During Construction
18 ("AFUDC") practices, and his list of capital addition,s includes these two units.
19
20 Q. PLEASE BRIEFLY DESCRIBE MPS UNITS 3 AND 4.
21 A. The MPS site was a greenfield (i.e., undeveloped) site before the four rvIPS units
22 were built. MPS Units 3 and 4 weré built after Units 1 and 2, which entered service
23 in March 2015. MPS Units 3 and A; like Clnits 1 and 2, consist of General Electric
24 LMS100 simple cycle aero derivative combustion turbines fueled by natural gas, with
25 fuel oil as an emergency backup. Although each unit has a nameplate rating of
26 100 MW at Internationl Organization for Standardization ("ISO") condition, MPS
8 DIRECT TESTIMONY OF ANDRES R. RAMIREZ
698
1
Units 1 and 2 are rated at 88 MW under summer conditions and MPS Units 3 and 4
are rated at 89 MW under summer conditions, owing to the high summer
3
temperatures and the high elevation of the MPS. Compared to EPEs older local
4
units, MPS Units 3 and 4 can be started quickly and are designed to be ramped up
5, and down to meet load fluctuations. Their heat rates are also more efficient than
6
those of the older units. CCN authorization for Units 3 and 4 occurred in Docket
7
No. 41763, as EPE witness David C. Hawkins explains.
8
9 Q. DOES 'EPE HAVE ANY OTHER GENERAL ELECTRIC LMS100 SIMPLE CYCLE
10 AERO DERIVATIVE COMBUSTION TURBINES?
•11 A. Yes, Rio Grande Unit 9, which entered servith in 2013, iš also a General- Electric "
12 LMS100 simple-cycle aero-derivative combustion turbine.
13
14 Q. WHAT ARE THE COMMON FACILITIES AT THE MONTANA- POWER STATION?
15 A. The common. facilities at the MPS are those facilities that support all of the units at'
16 the plant. The common facilities fall .into several major categories or plant functions
1,7 including:
18 1. Land and security,
19 2. Water supply and treatment,
20 3. Gas deliyery and distribution,
21 4. Compressed air system,
22 5. Fire protection,
23 6. Power distribution, and
24 7. Administrative and support activities.
25 Land and security include's the cost of the land, fencing, and other security
26 facilities at the plant. These facilities are not distinguishable between units at the
