Re: Tariff Advice No. IPC-E-TAE-23-02
Annual Compliance Filing to Update Charges, Credits, and General Overheads
under Rule H, New Service Attachments and Distribution Line Installations or
Alterations

Dear Commission Secretary:
Pursuant to Commission Rule of Procedure1 134 (IDAPA 31.01.01.134.01), Idaho
Power Company (“Idaho Power” or “Company”) hereby submits proposed cost updates
to the charges, credits, and general overhead rate outlined in Rule H, New Service
Attachments and Distribution Line Installations or Alterations (“Rule H”). This is the annual
compliance filing to update Rule H charges and credits as required by Idaho Public
Utilities Commission (“Commission”) Order Nos. 30853 and 30955. The Company also
requests to update its general overhead rate pursuant to Order No. 32472. The following
tariff sheets identify the proposed cost updates, allowances, and change to the general
overhead rate:

The cost estimation methodology used to update the charges and credits in this
tariff advice is the same methodology the Company utilized in previous annual filings. All
proposed cost updates are summarized in the attachments to this advice filing; the
charges are presented comparatively to the prior year’s filing and are also broken out by
the cost of Company vehicles/equipment, labor, materials, and trench, where applicable.
Overall, the proposed Rule H charges generally increased primarily due to
increases in labor costs, in addition to increased costs for certain materials as well as
the slight increase to the general overhead rate. However, the decrease in vehicle costs,
as described below, helped offset a portion of these increased costs. Single phase and
three phase allowances, provided to customers as an offset to their upfront cost
responsibility, increased by 13 percent and 14 percent, respectively.
More details on the inputs driving the proposed cost updates are provided below:
Labor Costs
The construction labor rate (the labor rate used to develop the charges and
credits) increased from $81 to $88. Additionally, the Engineering Charge increased by
approximately 7 percent, which results in the proposed Engineering Charge increasing
from $87 to $93 per hour.
Material Costs
The cost of materials included within the Underground Service Attachment
Distance Charge for Company Installed 1/0 and 4/0 underground cable decreased by 16
percent and 7 percent, respectively, while the overall cost of materials for Company
Installed 350 cable increased by less than one percent. The cost of materials included in
that same category of charges for Customer Provided Trench and Conduit saw an 11
percent reduction for 1/0 conductor, while the cost of 4/0 and 350 conductor increased
by 6 percent and 13 percent, respectively. However, these cost increases for 4/0 and
350 conductor were predominantly offset by the approximate 20 percent and 10 percent
decreases in two- and three-inch Schedule 40 conduit, respectively, which is included as
part of the applicable Company installation type.
The Company’s stores loading rate, which captures the cost of supervision, labor
and expenses incurred for the purchasing, storage, handling and distribution of materials
and supplies, decreased from 8.75 percent to 6.5 percent.
Vehicle Costs
A line truck and bucket truck are the primary vehicles utilized to perform Rule H
type work and the hourly rate for both vehicles decreased by 6 percent, or from $57.99
to $54.51. The decreased hourly rate for these vehicles is due to the Company incurring

lower fuel and maintenance expenses. Because vehicle costs make up approximately
10 percent, on average, of the total costs associated with the proposed Rule H charges
and credits, the decreased vehicle rate results in a moderate decrease to each of the
proposed Rule H charges and credits.

Single Phase and Three Phase Allowances

Allowances are provided as a credit to offset a portion of the upfront cost of
terminal facilities paid for by customers pursuant to Rule H. The proposed updates to the
Company-funded allowance amounts increased for both the single phase and three
phase allowances, primarily due to the increased cost of transformers, which was
partially offset by the decrease in vehicle costs and stores loading rate, as noted above.
The Company proposes to update the single phase allowance from $3,360 to $3,813,
and the three phase allowance from $6,890 to $7,863.
Idaho Power respectfully requests that the proposed updates are approved by
March 1, 2024, and become effective March 15, 2024. This 14-day implementation
period is necessary to update computer systems, prepare new communication materials,
and train personnel.
If you have any questions regarding this tariff advice, please contact Regulatory
Analyst Ashley Herrera at 208-388-2656 or [e-mail].

1. Definitions (Continued)

Unusual Conditions are construction conditions not normally encountered, but which the
Company may encounter during construction which impose additional, project-specific costs.
These conditions may include, but are not limited to: frost, landscape replacement, road
compaction, pavement replacement, chip-sealing, rock digging/trenching, boring, nonstandard
facilities or construction practices, and other than available voltage requirements.

Costs associated with unusual conditions are separately stated and are subject to refund if not
encountered. If unusual conditions are not encountered, the Company will issue the appropriate
refund within 30 days of completion of the project’s reconciliation of costs.

Upgrade is a request by a customer to increase capacity and/or size of Company-owned
distribution facilities. Upgrades are eligible for Vested Interest Refunds.

Vested Interest is the right to a refund that an Applicant or Additional Applicant holds in a specific
section of distribution facilities when Additional Applicants attach to that section of distribution
facilities.

Vested Interest Charge is an amount collected from an Additional Applicant for refund to a Vested
Interest Holder.

Vested Interest Holder is an entity that has paid a refundable Line Installation Charge to the
Company for a Line Installation. A Vested Interest Holder may also be an entity that has paid a
refundable charge to the Company under the provisions of a prior rule or schedule.

Vested Interest Refund is a refund payment to an existing Vested Interest Holder resulting from
a Vested Interest Charge to an Additional Applicant.

Vested Interest Portion is that part of the Company’s distribution system in which a Vested Interest
is held.

Work Order Cost is a cost estimate performed by the Company for a specific request for service
by an Applicant or Additional Applicant. The Work Order Cost will include general overheads of
10.69 percent.

5. Vested Interest Charges

Additional Applicants connecting to a vested portion of a Line Installation will pay a Vested Interest
Charge to be refunded to the Vested Interest Holder. Additional applicants will have two payment
options:

Option One - An Additional Applicant may choose to pay an amount determined by this
equation:

Vested Interest Charge = A x B x C where;

A = Load Ratio: Additional Applicant’s Connected Load divided by the sum of
Additional Applicant’s Connected Load and Vested Interest Holder's load.
B = Distance Ratio: Additional Applicant’s distance divided by original distance.
C = Vested Interest Holder’s unrefunded contribution.

Option Two - An Additional Applicant may choose to pay the current Vested Interest, in
which case the Additional Applicant will become the Vested Interest Holder and, as such,
will become eligible to receive Vested Interest Refunds in accordance with Section 8.a.

If Option One is selected, the Additional Applicant has no Vested Interest and the previous Vested
Interest Holder remains the Vested Interest Holder. The Vested Interest Holder's Vested Interest
will be reduced by the newest Additional Applicant's payment.
The Vested Interest Charge will not exceed the sum of the Vested Interests in the Line Installation.
If an Additional Applicant connects to a portion of a vested Line Installation which was established
under a prior rule or schedule, the Vested Interest Charges of the previous rule or schedule apply
to the Additional Applicant.

6. Other Charges

a. Alteration Charges. If an Applicant or Additional Applicant requests a Relocation, Upgrade,
Conversion or removal of Company facilities, the Applicant or Additional Applicant will pay
a non-refundable charge equal to the Cost Quote.

b. Engineering Charge. Applicants or Additional Applicants will be required to prepay all
engineering costs for Line Installations and/or Alterations greater than 16 estimated hours.
Estimates equal to or less than 16 hours will be billed to the Applicant or Additional
Applicant as part of the construction costs, or after the engineering is completed in
instances where construction is not requested. Engineering charges will be calculated at
$93.00 per hour.

c. Engineering Charges for Agencies and Taxing Districts of the State of Idaho. Under the
authority of Idaho Code § 67-2302, an agency or taxing district of the State of Idaho may
invoke its right to decline to pay engineering charges until the engineering services have
been performed and billed to the agency or taxing district. Any state agency or taxing
district that claims it falls within the provisions of Idaho Code § 67-2302 must notify Idaho
Power of such claim at the time Idaho Power requests prepayment of the engineering
charges. Idaho Power may require that the state agency or taxing district’s claim be in
writing. If the state agency or taxing district that has invoked the provisions of Idaho Code
§ 67-2302 does not pay the engineering charges within the 60-day period as provided in
that statute, all the provisions of that statute will apply.

d. Joint Trench Charge. Applicants, Additional Applicants, and subdividers will pay the
Company for trench and backfill costs included in the Cost Quote. In the event the
Company is able to defray any of the trench and backfill costs by sharing a trench with
other utilities, the cost reduction will be included in the Cost Quote.

e. Rights-of-Way and Easement Charge. Applicants or Additional Applicants will be
responsible for any costs associated with the acquisition of rights-of-way or easements.

f. Temporary Line Installation Charge. Applicants or Additional Applicants will pay the
installation and removal costs of providing Temporary Line Installations.

g. Temporary Service Attachment Charge. Applicants or Additional Applicants will pay for
Temporary Service Attachments as follows:

i. Underground - $74.00

The customer-provided meter post must be set within two linear feet of the
Company's existing transformer or junction box.

1. Definitions (Continued)

Unusual Conditions are construction conditions not normally encountered, but which the
Company may encounter during construction which impose additional, project-specific costs.
These conditions may include, but are not limited to: frost, landscape replacement, road
compaction, pavement replacement, chip-sealing, rock digging/trenching, boring, nonstandard
facilities or construction practices, and other than available voltage requirements.

Costs associated with unusual conditions are separately stated and are subject to refund if not
encountered. If unusual conditions are not encountered, the Company will issue the appropriate
refund within 30 days of completion of the project’s reconciliation of costs.

Upgrade is a request by a customer to increase capacity and/or size of Company-owned
distribution facilities. Upgrades are eligible for Vested Interest Refunds.

Vested Interest is the right to a refund that an Applicant or Additional Applicant holds in a specific
section of distribution facilities when Additional Applicants attach to that section of distribution
facilities.

Vested Interest Charge is an amount collected from an Additional Applicant for refund to a Vested
Interest Holder.

Vested Interest Holder is an entity that has paid a refundable Line Installation Charge to the
Company for a Line Installation. A Vested Interest Holder may also be an entity that has paid a
refundable charge to the Company under the provisions of a prior rule or schedule.

Vested Interest Refund is a refund payment to an existing Vested Interest Holder resulting from
a Vested Interest Charge to an Additional Applicant.

Vested Interest Portion is that part of the Company’s distribution system in which a Vested Interest
is held.

Work Order Cost is a cost estimate performed by the Company for a specific request for service
by an Applicant or Additional Applicant. The Work Order Cost will include general overheads of

5. Vested Interest Charges

Additional Applicants connecting to a vested portion of a Line Installation will pay a Vested Interest
Charge to be refunded to the Vested Interest Holder. Additional applicants will have two payment
options:

Option One - An Additional Applicant may choose to pay an amount determined by this
equation:

Vested Interest Charge = A x B x C where;

A = Load Ratio: Additional Applicant’s Connected Load divided by the sum of
Additional Applicant’s Connected Load and Vested Interest Holder's load.
B = Distance Ratio: Additional Applicant’s distance divided by original distance.
C = Vested Interest Holder’s unrefunded contribution.

Option Two - An Additional Applicant may choose to pay the current Vested Interest, in
which case the Additional Applicant will become the Vested Interest Holder and, as such,
will become eligible to receive Vested Interest Refunds in accordance with Section 8.a.

If Option One is selected, the Additional Applicant has no Vested Interest and the previous Vested
Interest Holder remains the Vested Interest Holder. The Vested Interest Holder's Vested Interest
will be reduced by the newest Additional Applicant's payment.
The Vested Interest Charge will not exceed the sum of the Vested Interests in the Line Installation.
If an Additional Applicant connects to a portion of a vested Line Installation which was established
under a prior rule or schedule, the Vested Interest Charges of the previous rule or schedule apply
to the Additional Applicant.

6. Other Charges

a. Alteration Charges. If an Applicant or Additional Applicant requests a Relocation, Upgrade,
Conversion or removal of Company facilities, the Applicant or Additional Applicant will pay
a non-refundable charge equal to the Cost Quote.

b. Engineering Charge. Applicants or Additional Applicants will be required to prepay all
engineering costs for Line Installations and/or Alterations greater than 16 estimated hours.
Estimates equal to or less than 16 hours will be billed to the Applicant or Additional
Applicant as part of the construction costs, or after the engineering is completed in
instances where construction is not requested. Engineering charges will be calculated at
$8793.00 per hour.
