The Company has updated line extension costs based on updates to the Company’s Construction & Material Standards as well as an updated actual average costs of all material and labor used in line extensions during 2013. Further, as explained below, the Company has updated its line extension allowances. Construction & Material Standards – The Distribution Engineering department at Avista is primarily tasked with the development and maintenance of the Company’s Construction & Material Standards. On occasion, Distribution Engineering will update the Construction & Material Standards in order to comply with the National Electric Safety Code (“NESC”). These Construction & Material Standards were recently updated to reflect the NESC’s 2012 code revision which included 377 individual changes, with the vast majority of these changes impacting the overhead distribution system. Significant changes include higher strength requirements for guy supported wood poles, and guy wire insulation upgrades to prevent transmission of voltage from the utility supply space to the communication worker space. Changes to the codes require that the Company review our standard designs and adapt them as necessary. Those standard design changes provide RECEIVED 2014 March 14 PM 3:09 IDAHO PUBLIC UTILITIES COMMISSION Avista Advice No. ADV 14-02-E Schedule 51 Revisions March 14, 2014 Page 2 of 3 Service Schedule Current Allowance Proposed Allowance Schedule 1 Individual Customer (per unit)$1,000 $1,600 Schedule 1 Duplex (per unit)$800 $1,275 Schedule 1 Multiplex (per unit)$600 $975 Schedule 11/12 (per kWh)$0.10703 $0.13766 Schedule 21/22 (per kWh)$0.06000 $0.11657 Schedule 31/32 (per kWh)$0.06000 $0.19689 for an accurate and fair representation of the distribution facilities installed by the Company and therefore are reflected in the proposed Schedule 51 costs in this filing. Transformer Cost Trends – One of the more significant cost increases included in this filing are related to the cost of distribution transformers. The primary reasons for the increase in transformer costs are twofold. The first relates to the increased cost of the transformer itself. The U.S. Department of Energy publishes standards related to the overall power transfer efficiency of transformers. Over the last several decades, transformer manufacturers have steadily progressed towards lower electrical loss units in order to meet conservation energy targets. In turn, the magnetic core grade steel of transformers has improved, albeit at an increased cost. Secondly, when the Company updated its Construction & Material Standards some of the materials that were previously included with “Primary” and/or “Service” related costs were shifted to transformer costs. In the Company’s current Schedule 51 rates, the cost for the transformer is only the cost of the transformer itself. It does not include other materials that are required for installing the transformer, as those costs were included in the Primary or Service components. The updated Construction and Materials Standards now shift transformer related costs to the transformer, resulting in increased transformer costs and an offsetting reduction to Primary and Service costs. Allowances – In this filing, the Company has updated the allowances applicable to new residential, commercial and industrial customer’s services. The current level of allowances were last updated in February 2001 in case No. AVU-E-00-01 (Order No. 28562). For purposes of calculating the revised allowances, the Company utilized an embedded cost methodology approach that is designed to ensure that investment in distribution/terminal facilities for each new customer will be equal to the embedded costs of the same facilities used to calculate base rates. Any costs in excess of the allowance would be paid by the new customer as a Contribution in Aid of Construction. The Company utilized the Cost of Service study from its most recent general rate case filing (AVU-E-12- 01), updated for the approved Settlement Agreement as the basis of the embedded cost calculation. Below is a summary of the proposed allowance changes: The Company has provided workpapers that provide the inputs and calculation of the allowances. Avista is supportive of this methodology, and we believe it is consistent with Commission Staff’s preferred allowance calculation methodology.

Enclosed as Attachment 1 is a copy of the workpapers supporting the line extension cost revisions contained in the proposed tariff sheets. In addition, during the week of March 17, 2014, the Company will send a letter to those developers and builders that may be affected by the proposed changes.

Allowances shall be granted only against the Basic Cost and Exceptional Costs of the current project and not against any part of an earlier or future extension. The Allowance will be the sum of the Basic Cost and any Exceptional Costs, or the applicable amount listed below, whichever is less: MAXIMUM ALLOWANCE Schedule 1 individual Customer $1000 per unit Schedule 1 duplex $ 800 per unit Schedule 1 multiplex $ 600 per unit EXCEPTION: The Company will not grant an immediate Allowance if the Company, in its sole judgement, determines that the load: a) is less than 2500 kWh per year, or b) will be in service less than five years. A mobile home will not qualify for an Allowance until it has permanent connections to both water service and either a sewer or septic system. If such connections are made within five years after the completion of the line extension, the Company will, at that time, refund the Basic Cost plus any Exceptional Costs, or the amount of the Allowance in effect at the time of the line construction, whichever is less. The Customer must apply for the refund before the line extension becomes six years old. Fifteenth Revision Sheet 51D Canceling I.P.U.C.

The Basic Cost is calculated from the charges in section 7. a. $4,814 + ($5.61 per ft x 2310 ft.) = $17,773. b. The average Basic Cost is $17,773/2310 ft = $7.69 per ft. 2. Exceptional Cost: a. If the cost estimate from the extension drawing is $18,000, the average estimated primary cost is $18,000/2310 ft = $7.79 per ft. b. The Exceptional Cost for a long extension is the difference between the estimated cost and the tariffed cost for the length greater than 1500 ft: EC = ($7.79 - $7.69) x (2310 ft - 1500 ft) = $81. 3. Total Primary Cost a. The Customer’s primary extension cost is $17,773+ $81 = $17,845. b. The total extension cost is calculated by combining all Basic Costs, Exceptional Costs, Allowance, Cost Reductions and Share of Previous Extension for the extension. 5) “Customer-Requested Cost” is the cost of unusual labor and/or materials which is requested by the Customer but which is not necessary to construct the Line Extension based on the Company’s minimum design, construction, and operating practices. All Customer-Requested Costs must be paid in full by the Customer. Customer-Requested Costs may include, but are not limited to, the following: a) facilities to provide three-phase service where single- phase service is adequate b) construction which is not for electric service c) facilities longer, deeper, or larger than deemed appropriate by the Company d) underground facilities in overhead areas e) soil compaction on private property Sixteenth Revision Sheet 51E Canceling I.P.U.C.

If 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 original line extension becomes six years old. Unclaimed refunds will be returned to the contributor. EXAMPLE: 1. First Customer pays $9,020 for 1,000 feet of primary underground circuit ($9.02 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 $9.02/ft x ½ = $2,706. 4. The Second Customer's payment of $2,706 will be refunded to the First Customer to reduce his investment in the 600 feet to $2,706. The First Customer's investment in the remaining 400 feet remains at $3,608. ($9,020-$2,706-$2,706=$3,608) EXCEPTION: If the refund to an existing Customer is less than $50 each, the new Customer will not be required to pay that share and the existing Customer will not receive a refund.
