Please provide a list of all regulatory authorizations required for the project.
Please identify the authorizations,if not obtained,that would cause the Company
to cancel or modify the project,and explain why it would affect the project and
specifically what action the Company would take.
Response to IPUC Data Request 7
The Company objects to this request as requiring speculation.Without waiving
this objection,the Company responds as follows:
The followingis a list of regulatory dockets seeking review of the repowering
projects and associated ratemaking treatment:
Case No.PAC-E-17-06-Applicationfor binding ratemaking treatment
for wind repowering before the Idaho Public Utilities Commission.
Docket 20000-519-EA-17-Applicationfor an order approving
nontraditional ratemaking related to wind repowering before the Wyoming
Public Service Commission.
Docket 17-035-39-Voluntaryrequest for approval of a resource decision
to repower wind facilities before the Public Service Commission of Utah.
The Company's decision to continue pursuing the opportunity without
authorization would depend,at least in part,on the findings and conclusions in
any applicable commission order,the opportunityto pursue traditional ratemaking
treatment for the projects,and the treatment of the mismatch of the costs and
benefits through any existing ratemaking mechanisms.

IPUC Data Request 9
Please detail all IRS requirements the Company has completed to date by project
site in order to qualify for 100%of the PTC's referenced by PAC-E-17-06.
Response to IPUC Data Request 9
Internal Revenue Code (IRC)section 45(a)provides for a current production tax
credit (PTC)for 2017 in the inflation adjusted amount of 2.4 cents per kilowatt-
hour (¢/kWh)of wind electricity produced for wind facilities for which
construction begins before January 1,2017.This is known as the 100-percent
PTC amount.IRS Notice 2013-29 Section 5 and 2016-31 Section 6 provide that
if five percent or more of the total cost of a repowered wind facility is incurred
before January 1,2017,then the wind facility will be deemed to be under physical
construction before January 1,2017,and will therefore qualify for the 100 percent
PTC.In December 2016,the Company procured wind turbine generator (WTG)
equipment of sufficientvalue to meet the five-percent safe-harbor requirement for
each repowering project.Please refer to Confidential Attachment IPUC 9,which
provides calculations of the five-percent safe-harbor requirement for each
repowered wind project.
Confidential informationis provided subject to the protective agreement in this

Please detail all remaining IRS requirements by project site which the Company
has yet to complete in order to qualify for 100%of the PTC's referenced by
PAC-E-17-06.
Response to IPUC Data Request 10
Internal Revenue Service (IRS)Notice 2016-31 provides that the continuity
requirement of continuous physical construction must be met.Section 3 of the
Notice provides that the continuityrequirement will be met if the wind facilities
are placed in service no later than the end of the fourth calendar year following
the calendar year that physical construction began.Accordingly,all project sites
are using the five-percent safe harbor to establish that physical construction began
before January 1,2017.Therefore,to qualify for 100 percent of the production
tax credit (PTC)value underthe four-year safe harbor,the repowered wind
facilities must achieve commercial operations by December 31,2020.

Response to IPUC Data Request 12
The Company's proposed repoweredwind projects will meet the start-of-
physical-construction requirement through the use of the five-percent safe harbor
as set out in InternalRevenue Service (IRS)Notice 2013-29 Section 5 and IRS
Notice 2016-31 Section 6.
As described in the Company's response to IPUC Data Request 10,the Company

If the Company does not meet the December 2020 completion project date,please
describe in detail the Company's contingency plans to obtain 100%eligibilityof
PTCs.
Response to IPUC Data Request 13
The Company expects the repowering projects to meet the December 2020
completion date,and has plannedthe repowering project construction schedule so
that more than 87 percent of the wind turbines that will be repowered (all projects
except Dunlap)are placed into service more than a year ahead of the deadline.
The Company has not developed specific contingency plans to obtain 100-percent
production tax credit (PTC)eligibilityif repowered wind turbines are not placed
in commercial operation by December 31,2020.
Internal Revenue Service (IRS)guidance provides certain provisions for wind
projects to demonstrate PTC eligibilityvia certain "start of construction"and
"continuous construction"parameters,which would be assessed by the IRS on a
case-by-case basis,but may also allow 100-percent PTC eligibilityto be
maintained with an in-service date beyond December 31,2020,as a contingency

follows:
The Company has identified the contribution of 100 percent of the production tax
credits (PTC)from the assumed repowering of 999 megawatts (MW)of wind
resources in its economic analysis.Please refer to the rows "PTCs"in Link
Exhibit No.10,which shows that 100 percent of the PTCs contribute $822
million in present-value benefits in each price-policy scenario.The effect of
reduced PTC benefits can be estimated by applying a percentage adjustment to the
PTC benefits included in the Company's economic analysis.

The Company has not quantified the likelihood of not receiving 100 percent of the
production tax credits (PTC),but such a result is highly unlikely.The Company
intends to receive 100 percent of the PTCs by ensuring that the safe-harbor and

In order for customers to realize the full net benefits of the project as proposed by
the Company,the Company will need to execute its plan on schedule and under
proposed cost estimates.Below are three potential conditions that would put
ratepayer net benefits at risk.For each circumstance below,please describe how
the Company would ensure customers are compensated for lost benefits or
increased costs that are the Company's responsibility:
(a)Reduction in PTC Benefits related to non-attainment of IRS Safe Harbor
requirements (not meeting requirements necessary for 100%of PTC).
(b)Reduction in PTC,NPC,and wholesale wheeling revenue benefits related to
late schedule completion.
(c)Cost overruns due to construction,capital infrastructure cost,permitting,etc.
Response to IPUC Data Request 16
The Company objects to this request as vague,ambiguous,and speculative.
Without waiving these objections,the Company responds as follows:
(a)The Company fully expects it will successfully meet the requirements
necessary to ensure eligibilityof the 100 percent of the production tax credits
(PTC)and receive net power costs (NPC)benefits available through the
repoweredwind projects.The Company anticipates passing on to customers
all of the realized benefits.The Company is not proposing to provide
customers benefits greater than or less than those received by the Company.
(b)Please refer to the Company's response to subpart (a)above.Wholesale
wheeling revenue is not expected to be affected by wind repowering.
(c)The Company believesthat its projection of costs and benefits of wind
repowering are reasonable and achievable and,as stated beginning on page
two in the Direct Testimony of Company witness,Rick T.Link,"...net
benefits,which include federal PTC benefits,net power cost ("NPC")
benefits,other system variable-cost benefits,and system fixed-cost benefits,
more than outweigh net project costs."The Idaho Public Utilities
Commission will have the opportunityto review the construction costs and
implementation of the repoweredprojects and make a determination on the
prudence of the actual costs incurred.

Please list and quantifythe potential for schedule delay related to:
(a)Jurisdictional approval;
(b)Permitting;
(c)Procurement;
(d)Construction.
Response to IPUC Data Request 19
(a)The current procedural schedules that have been set by each commission
anticipate final orders in line with the Company's proposed timelines and
project implementation schedule.Additionally,the Wyoming Public Service
Commission (WPSC)determined in June 2017 that a Certificate of Public
Convenience and Necessity (CPCN)is not required for the repowering
projects to be implemented in Wyoming.
(b)Permitting requirements related to the repowering projects are minimal,
requiring no new siting,environmental or other permits.While county
conditional use permits and local buildingpermits will be necessary for some
projects,the Company does not anticipate any schedule delays associated with
permitting of the repowering projects.
(c)The Company's project schedule provides sufficienttime for the procurement
of the wind turbine generator equipment consistent with contractual
requirements,while also providing ample time for the Company to procure
turbine installation contracts where necessary.Assuming jurisdictional
approvals are obtained consistent with the procedural schedules set by the
commissions,the Company does not anticipate procurement issues delaying
the project schedule.
(d)The Company's construction schedule results in more than 87 percent of the
wind turbines being repoweredin 2019,more than a year before the
December 31,2020 deadline.In addition,the Company's proposed
construction schedule results in repowering activities taking place during the
spring,summer and early fall periods when weather and wind conditions are
most favorable for construction activities.The Company is unable to quantify
the potential for construction-related delays,which can be heavilyinfluenced
by weather conditions.

Has the Company considered and quantified other locations for siting wind that
would qualify for the PTC and not require retirement of existing capital?If so,
please provide the analysis and the results.If not,why not?
Response to IPUC Data Request 20
The Company has considered other locations for siting wind resources that would
qualify for the production tax credit (PTC)but not require retirement of existing
capital.In 2016,the Company issued a request for proposals for renewable
resources (2016R RFP).In response,the Company received 19 wind project
proposals,all of which were evaluatedand determined to have higher costs for
customers than other alternatives.
Wind resources in Wyoming are expected to have superior generation
performance compared to the wind resources evaluatedin the 2016R RFP.The
2017 IntegratedResource Plan (IRP)identified new Wyoming wind resources as
part of PacifiCorp's least-cost,least-risk plan,and all of the resource portfolios
produced during the initial stages of the portfolio developmentphase of the 2017
IRP contained new Wyoming wind resources in 2021,which for modeling
purposes was used as a proxy on-line date for PTC-eligible wind resources in
commercial operation by the end of 2020.The Company is currentlysoliciting
proposals for those additional wind resources through the 2017 Renewable
Request for Proposals.PacifiCorp also filed an application with the Idaho Public
Utilities Commission (IPUC)on June 30,2017,seeking approval for the new
transmission and new wind resources identified in the 2017 IRP (Case PAC-E-17-

untenable?
Response to IPUC Data Request 26
The Company objects to this request as vague,ambiguous,and requiring
development of a special study or information not maintained in the ordinary
course of business.Without waiving these objections,the Company responds as
follows:
PacifiCorp has not developed the requested break-evenanalysis;however,the
Idaho Public Utilities Commission (IPUC)can estimate the level of production
tax credits (PTCs)that would cause the repowering projects to achieve break-even
economics using data contained in the Direct Testimony of Company witness,
Rick T.Link,specifically Link Exhibit No.10.This exhibit includes a line item
"PTCs"under Project Net Costs for each price-policy scenario.The present value
of revenue requirements differential (PVRR(d))for this line item can be
multipliedby a percentage that offsets the PVRR(d)for the "Net (Benefit)/Cost"
line item for any given price-policy scenario.
For instance,in the medium natural gas and medium carbon dioxide (CO2)price-
policy scenario,the PVRR(d)for wind repowering "PTCs"is $822 million,which
reflects the full value of PTCs.The PVRR(d)for the "Net (Benefit)/Cost"line
item is $359 million.If the PVRR(d)for the "PTCs"line item is multipliedby
approximately 56 percent,the "New Wind PTCs"line item would drop by
approximately $359 million,thereby causing the PVRR(d)for the "Net
(Benefit)/Cost"line item to be zero (i.e.,break-eveneconomics).

Construction or Continuous Efforts Tests can be supported.The five-percent is a
safe harbor and the deliveryof a significant amount of wind turbine components
for a wind project in 2016 could still qualify the project as being under
construction in 2016.Please refer to the Company's response to IPUC Data
Request 12 regarding the continuitysafe-harbor requirements of Internal Revenue
Service (IRS)Notice 2016-31 and IRS Notice 2017-4 Section 3.The Company

IPUC Data Request 32
Please provide the ongoing depreciation expense calculation,and all other costs
currentlyin rates,by project,by year,for the recovery of the plant equipment that
is replaced due to the wind powering project.Does the Company anticipate that
these costs will continue to be recovered in the next general rate case?Does the
Company anticipate there is any salvage value in the replaced plant equipment?
If so,please quantify.
Response to IPUC Data Request 32
Please refer to Confidential Attachment IPUC 32,which details by wind project
the asset balances as of the project repowering date and projected annual
depreciation for the plant equipment that is to be replaced in wind repowering.
The Company proposes that the replaced investment be included in the next
depreciation filing and that depreciation rates be set to recover the undepreciated
wind investment in any subsequent general rate case.
The Company acknowledges that the potential for salvage value benefit may be
available for the replaced equipment.However,the Company has not quantified
the amount of salvage.To the extent that any salvage value is realized,the
Company would credit the accumulated depreciation reserve by that amount,thus
making that benefit available to customers.
Confidential information is provided subject to the terms and conditions of the
protective agreement in this proceeding.

Please provide and explain the costs associated with modifyingthe current
interconnection agreements.
Response to IPUC Data Request 34
To modify the existing large generator interconnection agreement (LGIA)limits,
system impact and facility studies are required to evaluate the effects of the
additional power output on the transmission system.The Company filed
generation interconnection applications for the additional generationat the
existing points of interconnection (POI)for the planned repowering projects
described in the application,except for Leaning Juniper and Goodnoe Hills.
PacifiCorp's transmission function is currentlyreviewing the applications and
preparing the required studies under PacifiCorp's Open Access Transmission
Tariff (OATT).These studies are currentlyon-going and will determine the final
system modification costs once completed.System impact studies are expected to
be completed in December 2017.The completed studies will provide information
on the transmission upgrades,if any,needed to accommodate the interconnection
request.
The Company expects to file generationinterconnection requests for Leaning
Juniper and Goodnoe Hills with the transmission provider (BonnevillePower
Administration)by October 27,2017.
