RESPONSE TO REQUEST FOR PRODUCTION NO. 53:
a. Budget ID CHQB190012 is associated with a multi-year project that will upgrade
the bathrooms on each floor of the Corporate Headquarters ("CHQ") building. The
costs identified in the Company's Response to Request for Production No. 5 —
Confidential Attachment are specific to the remodel of the CHQ basement
bathrooms. There is no project plan document however the following provides
more information related to the project:
i. The costs associated with Budget ID CHQB190012 included in the Company's
request in this case are associated with the remodel of the CHQ basement
bathrooms due to a large water leak caused by excessive rain and the
overpowering of the city storm water system. This caused a 10" drain line to fail
in the CHQ basement above both bathrooms and locker rooms. This project
was scheduled and budgeted for 2026 but due to the extreme damage it was
moved forward and completed in 2024. While the CHQ basement bathroom
was not originally scheduled for a remodel until 2026, the original scope of
refurbishing the restrooms with new tile, plumbing fixtures, toilet partitions,
IDAHO POWER COMPANY'S RESPONSE TO THE SEVENTH PRODUCTION REQUEST OF THE
COMMISSION STAFF TO IDAHO POWER - 5

lighting and ceiling tile remained the same. The circulation core area of each
floor was to receive new lighting and floor covering.
ii. This was an unscheduled, unbudgeted project for the year it occurred. It was
scheduled for 2026 with a budget of $600,000 but needed to be accelerated
and completed earlier due to the extensive damage that was caused by the
failed drain piping. Once identified as needed in 2023, the project was bid out
to multiple contractors, and the lowest bid awarded the project.
iii. The initial schedule was to have the restrooms and core area completed by
February 2024.
iv. See the Company's Response to Request for Production No. 17(a)(iv) for an
explanation of the capital project budget approval processes. This project was
approved in Budget Update 4 during the fourth quarter of 2023 with a total
budget of $602,895 due to the failure of the drain piping.
b. There is no construction project plan document as construction plans have not
changed since the initial scope.
i. The project scope did not change following identification in the initial scope.
ii. There is no Microsoft Project Schedule WBS associated with this project. As
an alternative, the following is a summary of the actual project costs by year,
through July 31, 2024, and by detailed cost element, similar to the WBS
function in Microsoft Project Schedule. Please note, the chart below excludes
Allowance for Funds Used During Construction and overheads.

weeks. The second was related to the main drain line which was changed from
schedule 40 PVC to schedule 80 PVC for durability reasons.

IDAHO POWER COMPANY'S RESPONSE TO THE SEVENTH PRODUCTION REQUEST OF THE
COMMISSION STAFF TO IDAHO POWER - 8

REQUEST FOR PRODUCTION NO. 54: In its response to Production Request
No. 5, the Company identifies "Non-Criteria Based Equipment" with a cost of $287,746.
Please provide the business case for this expenditure, any other options that were
explored, their cost, and justification as to why this solution was chosen.
RESPONSE TO REQUEST FOR PRODUCTION NO. 54: The Non-Criteria Based
Equipment identification is associated with the purchase of equipment that is part of Idaho
Power's critical business function and used in day-to-day operations. The costs of
$287,746 closed to plant during the January 1, 2024 through June 30, 2024, as reflected
in the Response to Request for Production No. 5, are the result of two equipment
purchases: (1) the replacement of a trailer mounted four drum puller for $268,396, and
(2) the purchase of an additional zero-turn lawn mower for $19,350. In 2023, a member
of the public hit and totaled one of the 2,000 pound four-drum pullers utilized by the
Canyon and Payette operations centers. The four drum puller is a critical piece of line
equipment. A puller is used to pull wire through carriers so it can be placed on the cross
arms of a pole. The four drum puller allows for four power lines to be installed at one time.
Power is diffused from the engine to the reels over a hydraulic drive train.
The Company evaluated two four drum puller replacement options, one diesel-
powered with the same specifications as the totaled unit for approximately $175,000, and
an all-electric stringing equipment version for approximately $245,000. Due to the
immediate availability and its ability to charge on-board requiring fewer trips to the
operations center for fuel, diesel pullers had lead times of 10 to 12 months, the decision
was made to purchase the all-electric drum puller. The electric version includes safeguard
limits for the wire size and length that can be pulled, providing prevention of line breakage
IDAHO POWER COMPANY'S RESPONSE TO THE SEVENTH PRODUCTION REQUEST OF THE
COMMISSION STAFF TO IDAHO POWER - 9

and damage, while also operating at a quieter level than the diesel counterpart. In
addition, the Company received approximately $82,000 in insurance proceeds from
damage to the old drum puller, helping to offset the costs of the new drum puller. Note,
the insurance proceeds are recorded in Account 108 — Accumulated Provision for
Depreciation, offsetting the costs recorded in Account 101 — Electric Plant in Service.
Finally, the purchase also supports Idaho Power's movement towards electrification of its
fleet.
The second Non-Criteria Based Equipment purchase was a zero-turn lawn mower
for use at the CJ Strike parks complex. The CJ Strike parks complex includes over 100
campsites between the three parks, North Park and Scout Park, and Cottonwood Park,
consisting of over 60 acres of turf that needs mowed weekly. The complex is staffed with
three full time employees and one seasonal employee between the months of April and
September. The employees provide customer service, as well as grounds and facilities
maintenance seven days per week.
The turf was being managed with two zero-turn mowers, taking approximately 25
hours per week to mow the turf. With the addition of a third mower, that time will be cut
by approximately 30 percent, while also enabling an additional staff member to assist in
managing mowing when other work is complete. Also, the additional mower provides a
backup unit if one mower goes down and needs repair. Further, the Company purchased
an Exmark mower, the same manufacturer of the mowers used at CJ Strike and the
Oxbow parks currently because of familiarity with the units, interchangeable parts,
exceptional reliability, and excellent customer support from Horizon, the Exmark dealer.

IDAHO POWER COMPANY'S RESPONSE TO THE SEVENTH PRODUCTION REQUEST OF THE
COMMISSION STAFF TO IDAHO POWER - 11

REQUEST FOR PRODUCTION NO. 55: In its response to Production Request
No. 5, the Company identifies "AVTEC Consoles At Dispatch" project with a cost of
$171,995. The description provided did not provide clarity regarding the work that was
done. Please provide the following and if any of the information requested below cannot
be provided or is not available, please explain why it is not available or cannot be
provided:
a. Please provide a description and documentation on the other solutions that were
explored.
b. As the 5-year contract was expiring, it was known that either a contract renewal or
another solution was required to avoid a gap in support, please provide what steps
are being put in place to avoid a similar situation that would require an expenditure
of$150,000 in unbudgeted capital.
c. The Business Need provided indicates that an upgrade of dispatcher workstations
is planned for this year and that there are efficiencies in performing the work
simultaneously.
i. Please provide clarification if this was indeed completed as a single solution;
and
ii. Please provide the expected savings in the efficiencies mentioned on an
annual basis.
RESPONSE TO REQUEST FOR PRODUCTION NO. 55:
a. The Avtec console system was installed in 2018 as part of the project to replace
the Idaho Power two-way radio communication system. The purchase price of the
system at that time was $604,988. The Avtec consoles are comprised of hardware
IDAHO POWER COMPANY'S RESPONSE TO THE SEVENTH PRODUCTION REQUEST OF THE
COMMISSION STAFF TO IDAHO POWER - 12

peripherals connected to dispatcher workstations, with software installed on the
workstations that allows dispatchers to manage communications with field
employees. In 2017, an RFP was issued soliciting multiple console system
manufacturers. Avtec was the successful respondent due in part to technical
deficiencies of competitor solutions that were required to interface with the
Company's two-way radio system.
The $171,995 that closed to plant year to date June 2024 was due to the
replacement of a portion of the Avtec console system that had been discontinued.
Rather than replacing the entire system, which would include the replacement of
the hardware and software, the completion and testing of the required
communications systems integrations, and the training of dispatchers in the new
system, at a much higher cost, Idaho Power replaced only the part of the system
that was discontinued. Further, the upgrade extended the life of other components
that did not require replacement. Given the system initially cost $604,988 in 2017,
the partial replacement at $171,995 was a more cost-effective solution.
b. The contract was known and planned to expire at five years and both parties
anticipated a renewal to maintain support services although it was not planned that
the console hardware would need to be upgraded as the previous equipment
would no longer be supported. Avtec had communicated this to customers, but
Idaho Power inadvertently excluded the project costs in the 2024 budget. The
Company and Avtec have developed an annual process to review the published
end-of-life/end-of-support dates for communications systems to understand
IDAHO POWER COMPANY'S RESPONSE TO THE SEVENTH PRODUCTION REQUEST OF THE
COMMISSION STAFF TO IDAHO POWER - 13

manufacturer's technology roadmaps and inform Idaho Power's future strategy
and resulting budget.
C. (i). Yes, the hardware and software were changed simultaneously with the
upgrades of the dispatcher workstations.
(ii). The efficiencies referenced are in small part financial and in larger part due to
the reduced dispatcher operations impact of a single disruption versus multiple
disruptions. The update cadence of Avtec hardware and software products do
not always align with the cadence of workstation replacements. Idaho Power
was able to accomplish both tasks by coordinating the work.

Senior Manager, Idaho Power Company.
IDAHO POWER COMPANY'S RESPONSE TO THE SEVENTH PRODUCTION REQUEST OF THE
COMMISSION STAFF TO IDAHO POWER - 14

REQUEST FOR PRODUCTION NO. 56: In its response to Production Request
No. 5, the Company identifies "CHQ-6 Conference Room Furniture" project with a cost of
$153,419. The description provided did not provide clarity regarding the work that was
done. Please provide the following and if any of the information requested below cannot
be provided or is not available, please explain why it is not available or cannot be
provided:
a. Please explain what was done with existing furnishings. If the existing furnishings
were resold, please specify for what amount; and
b. Please explain why the conference room redecorating needs to be completed with
the "Bathroom/Core Upgrade Each Floor At CHQ" as stated in the Business Need
for this project. Please provide additional details of savings from completing this
work simultaneously.
RESPONSE TO REQUEST FOR PRODUCTION NO. 56:
a. The existing furniture was disposed of due to age and quality.
b. There were separate Budget ID's for the CHQ Restroom/Core upgrades and the
CHQ Conference Room Upgrades, BIDs CHQB190012 and CHQB190014,
respectively. The conference room upgrades were designed and bid along with the
restroom and core upgrades in order to reduce costs by combining scopes into a
larger project and providing better pricing on lighting orders. The consolidation also
caused less disruption on each floor as both projects could be completed at one
time.

Senior Manager, Idaho Power Company.
IDAHO POWER COMPANY'S RESPONSE TO THE SEVENTH PRODUCTION REQUEST OF THE
COMMISSION STAFF TO IDAHO POWER - 15

REQUEST FOR PRODUCTION NO. 57: IPC-E-24-07 response to Production
Request No. 5 identifies "Purchase 3 Destination Trlrs For Seasonal Wrkrs At HCC" with
a cost of $254,075. Please provide the following and if any of the information requested
below cannot be provided or is not available, please explain why it is not available or
cannot be provided:
a. Please provide the business case for this expenditure, any other options that were
explored, their cost, and justification as to why this solution was chosen;
b. Does the Company charge rent to the seasonal workers? If so, please provide the
total rent revenue;
c. Please explain what is done with the trailers in the off-season;
d. Please explain what "Park" the Company is referencing in the Business Need of
the project; and
e. Please explain the roles and responsibilities of each of the seasonal workers at
HCC referenced in the response.
RESPONSE TO REQUEST FOR PRODUCTION NO. 57:
a. There is no business case document specific to this project, the purchase of three
trailers for seasonal workers at the Hells Canyon Complex ("HCC"). Idaho Power
continually investigates lowest-cost housing options for employees working in
remote locations and explored RV hook up sites for the HCC seasonal workers.
However most seasonal workers do not have access to an RV. In the past, the
Company rotated seasonal employees through other field houses but was having
conflicts with other Idaho Power crews using the houses.
b. Idaho Power does not currently charge rent to the seasonal employees however
IDAHO POWER COMPANY'S RESPONSE TO THE SEVENTH PRODUCTION REQUEST OF THE
COMMISSION STAFF TO IDAHO POWER - 16

seasonal employees are responsible for replacing the propane they use and
providing upkeep on the unit they occupy.
c. The trailers will be winterized at this time however the Company anticipates they
will be used, year-round, post- HCC license issuance, because work will
intermittently continue into the fall and winter (e.g. fish weir monitoring, recreation
use surveys, and construction projects at our parks).
d. The trailers are used for seasonal employees who work at any of Idaho Power's
four major overnight parks: Hells Canyon Park, Copperfield Park, McCormick Park,
and Woodhead Park. In addition, they will be used at less-developed sites like
Carter's Landing, Copperfield Boat Launch and Oxbow Boat Launch.
e. Seasonal employees conduct maintenance including plumbing, irrigation, mowing,
pruning, weed control, light carpentry including painting, repairing park amenities,
and replacing signs. Employees also provide customer service, such as explaining
rules, access information, and liaising between law enforcement and the
Company. They also monitor systems, including sewer lift pump status, irrigation
timers, irrigation intakes, and public drinking water.

IDAHO POWER COMPANY'S RESPONSE TO THE SEVENTH PRODUCTION REQUEST OF THE
COMMISSION STAFF TO IDAHO POWER - 17

REQUEST FOR PRODUCTION NO. 58: Please provide the information
requested as it pertains to the "GridMod Single Vendor Platform" project discussed in
Company witness Colburn's Direct at 28. If any of the information requested below cannot
be provided or is not available, please explain why it is not available or cannot be
provided.
a. Please explain and reconcile the different in-service dates, and differences in the
projects, if any, for the first phase of this project from the following information
provided by the Company:
i. In response to Production Request No. 35 in the 2023 Rate Case, Confidential
Attachment 1 has an in-service date of 7/31/2020 for "IVVC GridMod Project
Phase 4";
ii. In response to Production Request No. 36 in the 2023 Rate Case, Confidential
Attachment 1 has an in-service date of 1/31/2023 for "GridMod Single Vendor
Platform"; and
iii. In this rate case, Colburn Direct at 30 identifies an in-service date of October
2024 for this project.
b. Please provide the annual expenses related to the software vendors providing
Energy Management Systems, Outage Management System and a Distribution
Management System / Integrated Volt/VAR Control services for the past three
years.
c. Please provide the total estimated capital expense and annual O&M expense for
the "GridMod Single Vendor Platform." Please provide supporting workpapers.
IDAHO POWER COMPANY'S RESPONSE TO THE SEVENTH PRODUCTION REQUEST OF THE
COMMISSION STAFF TO IDAHO POWER - 18

d. Please provide the status of any funding that has been applied for or awarded
through the Infrastructure Investment and Jobs Act or any other source to offset
the cost of this project.
e. Please provide any expected savings from this project. Please identify where the
Company applied any savings in this rate case.
f. Please explain how this new platform will integrate with the existing software
systems used for wildfire mitigation.
RESPONSE TO REQUEST FOR PRODUCTION NO. 58:
a. The two projects, while both the results of Idaho Power's grid modernization
efforts, are different. In the 2023 Rate Case, the test year included the replacement
of an Automated Capacitor Control ("ACC") system with the development of a new
integrated volt-var control ("IVVC") system. The IVVC system replaced a 22-year-
old DOS-based system that was nearing its end of life and was unable to provide
direct and coordinated voltage control offered by more modern systems such as
the IVVC system. Replacing the ACC with the IVVC provided the Company with
the ability to better control devices and gather data in real-time, allowing the
Company to improve power quality and voltage levels, optimize efficiency, and
provide visibility and control to engineers and operators to better manage the
distribution system. The IVVC was placed in service in July 2020.
The single vendor platform, also a project that is a part of Idaho Power's
grid modernization initiative, included the consolidation of three vendor solutions,
into one. The Company currently leverages three stand-alone grid control systems
for managing the bulk electric system, optimizing distribution assets, and
IDAHO POWER COMPANY'S RESPONSE TO THE SEVENTH PRODUCTION REQUEST OF THE
COMMISSION STAFF TO IDAHO POWER - 19

responding to customer outages. The systems are the (1) Energy Management
("EMS")/Supervisory Control and Data Acquisition ("SCADA") system, (2) Outage
Management System ("OMS"), and the (3) IVVC, a Distribution Management
System ("DMS").
Because these systems are independent, they require three sets of
hardware, three network models, three support organizations, and complex
integrations between the systems. Consolidating the disparate systems will reduce
total cost of ownership, lower cyber security threats, and improve user proficiency
and organizational support. The three systems will still exist but under one
platform. The common architecture will allow Idaho Power to optimize internal
support structures through shared resources and reduce the Company's total cost
of ownership through bundling support and licensing costs.
The single vendor platform project, assigned Budget ID BOBN220002, is
anticipated to be placed in service in October 2024 and, as evidenced by the Work
Breakdown Structure provided in the Company's Response to Request for
Production No. 32(b)—Attachment 1 work began in 2023. Specific tasks necessary
for the project are assigned work order numbers and once completed and the
product is used and useful, the work order is placed in service, which may be prior
to the entire project being completed. The costs identified in the 2023 Rate Case
in the Response to Production Request No. 36 — Confidential Attachment 1,
included as the Response to Production Request No. 58(a) — Confidential
Attachment in this proceeding, with an in-service date of January 2023 were
IDAHO POWER COMPANY'S RESPONSE TO THE SEVENTH PRODUCTION REQUEST OF THE
COMMISSION STAFF TO IDAHO POWER - 20

associated with three work orders under Budget ID BOBN220002 that had been
placed in service.
b. The following summarizes the annual O&M expenses specific to the software
related to the EMS, OMS and IVVC services for the past three years:
2021 2022 2023
EMS 243,816 258,552 271,478
OMS 222,157 237,469 236,740
IVVC 143,793 175,023 182,587
Grand Total 609,766 671,043 690,805
c. See the Company's Response to Request for Production No. 32(a) — Confidential
Attachment 2 for the business case for the project. The estimated capital costs are
presented in Table 19 — Estimated project costs on Page 33 of the business case
while the annual O&M expenses are presented in Table 20 — Estimated ongoing
annual costs. Option C details the costs specific to the vendor selected for the
single vendor platform project.
d. The Company received a $1.5 million grant from the State of Idaho under the
Energy Resiliency Grant Program for the foundation phase of the single vendor
platform project.
e. See the Company's Response to Request for Production No. 32(a) — Confidential
Attachment 2 for the business case for the project. As presented on page 19, the
financial analysis results indicate expected revenue requirement savings of
approximately $3 million on a net present value basis.
