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.

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). 8 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: AVISTA'S ANNUAL ELECTRIC LINE EXTENSION FILING PAGE 3 1 Presd Proposed %Chaee $ s 2 3 4 5 6 7 8 9 OrrcrhcdPrinrv Cicuir Fhd e,ost Vdable Cost UrdercrmdEirrv Ctcrdt FhdCosts Viliabh Costs Urderer@d S€cmdtrv Circdt FkcdCosts Vari$h Costs OvcrbadSecmdrv Cicuit FhedCosts Orrcrtead S€rvi:€ Ciicuf Urdcrgroud Scrt'ice Ckmit OvtrteadTra$ormcr PadmmTrmtrorner t,732 $ 1,936 11.70/o $ $ $ $ 4.205 S 8_22 $ 1,934 $ 11.34 $ 428 $ 10.47 $ 3.74 $ 9.54 $ 2,A2 $ 3,546 $ 4,677 9.17 1,920 l0_01 394 8"60 4.27 8_43 2,345 1.417 Ll.2o/o ll-6c/o -0.7o/o -11-74/o -8.0olo -17-9/o 14.2o/o -11.601o 4.6Vo -1.9/o 10 S $ $ $ $ t1 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. I ThetransportationpoolcontainscostsforFleetServicestomaintainandoperateAvista'sequipment including labor, parts, ficensing, fuel, etc. 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. 10 Residential development costs, updated for the most current Constuction & 1 I Material Standards and average 2020 construction costs, are detailed below: r ^ Rcrldcuthl Dcvcloomcntstz 13 $ Prescut Prooorcd 1.938 | t.712 478 | 422 l4 15 t6 Total Cort pcr Lot Lceg: Scnicc Coet IDcvclopcr R*qronslblltty Dcvfucr Rcfimdablc Palmat Builds Non-Rcfimdabb Prymcot Allowsocc $ 1.,160 - $ 1.460s38 $ 1.900 $ r3s0 - $ 1.350t- $ 1,900 t7 V.
