II. BACKGROUND
The Company's present Schedule 51 electic line extension tariffincorporates tre
principle of average costing for electrical facilities commonly used in extending service.
The tariff sets forth "Basic Costs", which are costs based on recent average actual cosb
for facilities such as transformers and conduit which are used consistently for electric line
extensions. The Basic Costs have a fixed and variable component, with the variable
component stated on a cost-per-footbasis. The average costingprinciple incorporafed in
the Company's tariff has worked well and the Company is notproposingto change the
conceptual structureof the tariff.
Detailed below are the Company's proposed changes to Schedule 5l and included
with this filing are workpapers which provide support for the proposod changes.

III. CONSTRIICTI ON ALLOWANCES
2 The Company is not proposing to update the allowances in this filing. It is the
3 Company's practice to update the allowances afterthe conclusion of a general rate case.
4 The allowances were last updated in May 2020 based on the Cost of Service study from is
5 most recently concluded general rate case filing (AVU-E-19-04). The Company will
6 update the allowances in next year's filing, reflecting the final results of the Company's
7 pending general rate case (AVU-E-21-01).

IV. A COSTS
l0 The Disfibution Engineering Deparhnent at Avista is primarily tasked with the
l1 development and maintenance of the Company's Construction & Material Standards.
12 Periodically, Distibution Engineeringwill update the Constuction & Material Standards
13 in orderto comply with the National Electric Safety Code ("NESC"). These Construction
14 & Material Standards were last updated in 2017 to reflect the NESC's code revisions. The
15 standard designs in this filing have not changed and are consistent with those reflected in
16 this filing.
l7 As detailed on proposed tariff sheets 5l H and 5 I I, the Company is proposing tc
18 update the primary, secondary, service and transforrner average costs. Below is a
19 summary of the cost changes:

12 The primary driverofthe increasein overheadrates as shown above, isdueto a
13 decreaseinvehicleusage during2020. As anexample,theCompanyusesatandemdiggpr
14 in most overhead electrical work. The cost of using this piece of equipment is estima@d
1 5 as part of an overhead crew's cost to perform such work (this is done in what's called a
16 tansportation pooll). The tandem digger had a decrease of 3,457 miles used over the
17 prioryear, al7.SYoreduction Giventhattherearebothfixedandvariablecostsassociabd
l8 with vehicle maintenancg the overall costs for maintaining this type of equipment also
19 went down. However, the fixed costs held the balance in the pool high enough that the
20 rate had to be changed in order to spread the costs across fewer miles, resulting in an
2l increase in the amount of overhead vehicle costs assigned to these jobs.

AVISTA'S ANNUAL ELECTRIC LINE EXTENSION FILING PAGE 4
1 The primary driver of the decrease in underground rates is due to a business
2 process improvement in the way vehicle rates are applied in the Company's workorder
3 system. Historically, the Company has assigned vehicle costs basedon theirdefined rab
4 and assigned it to a job. For example, a Ditch Witch with tailer would have been charggd
5 to ajobat arate of $225. TheCompanyredefinedhowcostsareallocatedsuchthatwe
6 more accurately define the time and effortthatthe equipmentwould be used foron the
7 job and therefore are able to allocate a lowercost to underground work. Inthe Company's
8 view, this methodology more closely aligns with how vehicles are actually being utilized
9 in the field.

"Share of Previous Extension" applies only to Primary Circuits
less than five years old. lf part of a previous line extension is
used to serve a new Customer, the new Customer must pay a
share of the previous Primary Circuit cost and Transformer
cost, if shared, to the Company before the start of
construction. The amount paid by the new Customer will be
refunded to existing Customers in relation to their share of the
Primary Circuit and Transformer, if shared. The Company will
refund appropriate shares to the bearers of Extension
Certificates when the Certificates are presented for payment
and the connection of the subsequent Customer has been
verified. The Company will make a reasonable attempt to
inform the bearer of the Certificate when a refund is due.
Bearers of Extension Certificates must apply for refunds
before the origina! line extension becomes six years old.
Unclaimed refunds wil! be returned to the contributor.
D(AMPLE:
1. First Customer pays $10,010 for 1 ,000 feet of
primary underground circuit ($10.01 per foot).
2. Second Customer takes service within five years
using 600 feet of the original extension.
3. Both Customers share the first 600 feet equally:
600 ft x $10.01/ft xYz= $3,003.4. The Second Customer's payment of $3,003, will be
refunded to the First Customer to reduce his
investment in the 600 feet to $3,003. The First
Customer's investment in the remaining 400 feet
remains at $4,004. ($1 0,01 0-$3,003-$3,003=$4,004)
EXCEPTION: lf the refund to an existing Customer is
less than $100 each, the new Customer will not be
required to pay that share and the existing Customer

"Share of Previous Extension" applies only to Primary Circuits
less than five years old. lf part of a previous line extension is
used to serve a new Customer, the new Customer must pay a
share of the previous Primary Circuit costand Transformer
cost, if shared, to the Company before the start of
construction. The amount paid by the new Customer will be
refunded to existing Customers in relation to their share of the
Primary Circuit and Transformer, if shared. The Company will
refund appropriate shares to the bearers of Extension
Certificates when the Certificates are presented for payment
and the connection of the subsequent Customer has been
verified. The Company will make a reasonable attempt to
inform the bearer of the Certificate when a refund is due.
Bearers of Extension Certificates must apply for refunds
before the original Iine extension becomes six years old.
Unclaimed refunds will be returned to the contributor.
D(AMPLE:
1. First Customer pays $10.010 for 1,000 feet of
primary underground circuit ($l_0.01 per foot).
2. Second Customer takes service within five years
using 600 feet of the original extension.
3. Both Customers share the first 600 feet equally:
600 ftx$l!.1QL/ft xTz= $9.003.4. The Second Customer's payment of $3,003, wil! be
refunded to the First Customer to reduce his
investment in the 600 feet to $3.003. The First
Cuslomer's investment in the remaining 400 feet
remains at $4004. ($1 0.01 0-$3.003-$3.003=$a.00a)
EXCEPTION: lf the refund to an existing Customer is
less than $100 each, the new Customer will not be

4. RULES AND CHARGES FOR UNDEVELOPED RESIDENTIAL LOTS
a.A development is a group of neighboring undeveloped lots separated
by no more than streets and under the ownership or legal control of a
single pafi as determined by the Company. Both the General Rules
and the following rules apply to line extensions within
residential developments.
Before Company facilities will be installed, the developer must submit
a written application for service, a copy of the plat as approved by the
governing agency depicting dedicated utility easements approved by
the serving utilities and must pay an extension cost to the Company
which is computed as follows:
Basic Cost
Custom er-Requested Costs
Cost Reductions
(one) Design Fee of $150 (if paid)
extension cost within development
cost of extension to development
Share of Previous Extension
extension cost
1)"Basic Cost" willbe computed from the following rate per lot
when the Development serves single phase loads, has at least
six lots and the average frontage is no more than 175 feet per
Iot. The Basic Cost includes the cost of the Primary Circuit, the
Transformer and the Secondary Circuit in the utility easement
or public right-of-way, but does not include the Service Circuit
from the point of connection with the Secondary Circuit to the
Point of Delivery.

annually as new customers are connected within the Development. The
Developer will provide ditching within the Development.
There will be no charge to the builder forthe installation of the Service
Circuit to serve a duplex or multiplex dwelling.
A Developer who pays the extension cost described in 4.b.1) may apply

lndividual Customers will be used to establish the extension cost of
the Primary Circuit and that cost must be paid in advance by the
Developer.
The permanent Customer on each lot must meet the Rules for
lndividual Residential Customers forthe extension into the lot, except
