BACKGROUND The Company's present Schedule 51 electic line extension tariff incorporates flre principle of average costing for electrical facilities commonly used in extending service. The tariff sets forth 'oBasic Costs", which are costs based on recent average actual cosb for facilities such as tansformers and conduit which are used consistently for electic line extensions. The Basic Costs have a fixed and variable component, with the variable component stated on a cost-per-footbasis. The average costingprinciple incorporabd in the Company's tariff has worked well and the Company is notproposingto change the conceptual structure of 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 proposed changes. AVISTA'S ANNUAL ELECTRIC LINE EXTENSION FILING PAGE 2 1 III. CONSTRIICTION 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 after the 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 9 IV. AVERAGE COSTS 10 The Distribution Engineering Departrnent at Avista is primarily tasked with the 11 development and maintenance of the Company's Construction & Material Standards. 12 Periodically, Distribution Engineeringwill update the Construction & Material Standards l3 in orderto comply with the National Electric Safety Code ("NESC"). These Construction 14 & Material Standards were lastupdatedin 2017 to reflectthe NESC's coderevisions. The 15 standard designs in this filing have not changed and are consistent with those reflected in 16 this filing. 17 As detailed on proposed tariff sheets 5 1H and 5 1I, the Company is proposing to 18 update the primary, secondary, service and tansformer average costs. Below is a 19 summary of the cost changes: AVISTA'S ANNUAL ELECTRIC LINE EXTENSION FILING PAGE 3 I kes€d Prooosod % Chaee $ s $ s $ s 2 3 4 5 6 7 8 9 Orrc*cadHinarv Ciodt FkedCost Vari&le Cost Urdercrffud Eimilt' Cir€uit Fhed Costs Vaiable Costs Urderermd S€cmdrv Ckcnit Fhcd Costs Vsiable Costs orrstcadSccmdrv Cfuuf FhedCosts Orrcrted Servhe Cjisult Undcrgroud Scrvbe Cislit Ovutcad Trasformcr PafumtTraodormer 4J05 8_22 1,934 11.34 $ $ $ $ 4,677 9.17 1,920 10.01 4_27 8_43 2,345 1.477 ll.2o/o ll.6c/a -0.7o/o -ll.7o/o $ $ $ $ s tJ32 $ 1.936 11.70/o 428 $ 10.47 $ 3.74 $ 9.54 $ 2.242 $ 3,546 $ 394 -8.0o/o 8.60 -L7.9/o 14.2o/o -ll.6o/t 10 4-6o/o -1.9/o 11 12 The primary driver of the increase in overhead rates as shown above, is due to a 13 decreaseinvehicleusage during2020. Asanexample,theCompanyusesatandemdiggsr 14 in most overhead electrical work. The cost of using this piece of equipment is estimated 15 as part of an overhead crew's cost to perform such work (this is done in what's called a 1 6 transportation pool l). The tandem digger had a decrease of 3 ,457 miles used over the l7 prioryear, al7 .5o/oreduction. Giventhatthere are both fixed andvariable costs associabd 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, licensing, 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 based on their defined rate 4 and assigned it to a job. For example, a Ditch Witch with tailer would have been charypd 5 to a job at a rate of $225. The Company redefined how costs are allocated such that we 6 more accurately define the time and effort that the equipment would be used for on the 7 job and therefore are able to allocate a lower cost to underground work. [n the Company's 8 view, this methodolory more closely aligns with how vehicles are actually being utilized 9 in the field. l0 Residential development costs, updated for the most current Construction & 11 t2 13 t4 l5 l6 t7 18 19 2t Material Standards and average 2020 constructioncosts, are detailed below: Rcddcutlel Dcvclooucntr Total Cort pcr Lot Lcss: Scnicc Coct Dcrreloper Rrponslblllty Dardopcr Rcfiodabh Palmot Builda Non-Rcfindablc Paymcnt Prcscnt s 1.938 $ 478 $ 1.'t60 $ r.460 $38 Propored $ t.772 I 422 s 1,350 $ 1.350 $- 20 Allowaocc $ 1.900$ 1,900 V.

Duringthe week of April 5,2021, the Company will send a letter to those developers and builders that may be affected by the proposed changos to inform them of the Company's request.

The Company filed its proposed changes with the Commission on March 29,2021, and if the requested changes are approved, they would go into effect on May 15,2021. The changes include updating the standard or basic development costs and allowance to reflect actual 2020 material and labor costs.
