Also included in Exhibit "A" is a copy of Seventeenth Revision Sheet 150 with the changes underlined and a copy of Substitute Sixteenth Revision Sheet 150 with the proposed changes shown by lining over the current language or amounts. V. The existing rates and charges for natural gas serce on fie with the Commission and designated as Applicant's Tarff IPUC No. 27, which wil be superseded by the rates and charges fied herewith, are' incorporated herein as though fully attached hereto. VI. In accordance with IDAPA 31.01.01, Rule 125, Avista wil provide notice of the decrease to its customers after Commission approval via a message on customer bils. Notice to the Public of Applicant's proposed tariffs is to be given simultaneously with the fiing of this Application by posting, at each of the Company's distrct offices in Idaho, a Notice of Tarff Change, a copy attached hereto as Exhibit "B". The Company wil also issue a press release which wil be distributed to various informational agencies on Monday, Februar 13,2012. A copy of the final Press Release wil be filed with the Commission. '-~(¡ VIII. The circumstances and conditions relied on for approval of Applicant's revised rates are as follows: Applicant purchases natual gas for customer usage and transports it over Wiliams Pipeline West (d.b.a. Nortwest Pipeline Corporation), Gas Transmission Northwest (GTN, TransCanada (Albera), TransCanada (BC) and Spectra Pipeline systems and defers the effect of timing differences due to implementation of rate changes and differences between Applicant's actual weighted average cost of ga~ (WACOG) purchased and the W ACOG embedded in rates. Applicant also defers varous pipeline refu~s. or charges and miscellaneous revenue received from natual gas related transactions including pipelin~ capacity releases. IX. 'i,. This filing reflects the Company's proposed out of period Purchased Gas Cost Adjustment (PGA) to pass through to customers changes in the estimated cost of natual gas (Schedule 150) for dip fortcoming eight months of March 2012 through October 2012. Below is a table summarizing tp(eproposed changes reflected in this filing. . Commodity Demand Total Total Rate OveraU Sch.Change Change Sch.150 Change Percent Service No.pertherm perthm Change perther Change General 101 ($0.05581)$0.00000 ($0.05581)($0.05581)(5.68%) Lg. General 111 ($0.05581)$0.00000 ($0.05581)($0.05581)(7.30%),) Interrptible 131 ($0.05581)$0.00000 ($0.05581)($0.05581)(9.74%) e e X. Commodity Costs - Background As shown in the table above, the estimated commodity cost (WACOG) change is a decrease of 5.6 cents per thermo The proposed W ACOG is 36.2 cents per ther compared to the present W ACOG of 41.8 cents per therm included in rates. In its PGA filing in 2011, the Company used a 30-day historical average of forward prices ending August 22, 2011 by supply basin to develop an estimated cost associated with index/spot purchases. The estimated monthly volumes to be purchased by basin are multiplied by the (3D-day) average price for the corresponding month and basin. These index/spot volumes represented approximately 30% of estimated anual load requirements for the PGA year. XI. Commodity Cost - Change On average, daily wholesale prices of natual gas have declined substantially over the past several months. While a majority of the W ACOG is fixed either through fixed price hedges or storage injections, the one varable that is not fixed is the approximately 30% of estimated index/spot volumes. While we are now five months in to the present thirteen month PGA year (October 2011 through October 2012), the Company believes that it is in the best interest of customers to update the pricing of the remaining estimated index/spot volumes and pass those lower index prices to customers now though a lower overall rate. The Company also believes that this is in compliance with Order 32370 which, when approving tle Company's 2011 PGA, the Commission stated that "Avista promptly fie an application to amend. its WACOG should gas prices materially deviate from the presently approved $0.41797 per ther" rate. ' XII. Demand Costs and Amortization Rate Change 'I. The Company is not proposing to make any changes to the other components of Schedule 150 (demai4 costs, varable transportation, etc.) nor is it requesting any changes regarding the current amortization ratës (Schedule 155). Changes in those items wil occur with the normal anual PGA filing which wil be fied in September 2012. XIII. The average residential or small commercial customer using 62 therms per month wil see an decreaseqf $3.46 per month, or approximately 5.68%. The present bil for 62 therms is $60.96 while the proposed ~il1is $57.50. ' XIV. Exhibit "C" attached hereto contains support for the rates proposed by Applicant contained'ihExhibit "A".: XV. Applicant is requesting that Applicant's rates be approved to become effective on March 1, 2012 with less than statutory notice. The Applicant therefore, pursuant to Rule 135 (IDAPA 31.01.01),ia;) ~,--, e e requesting that the Commission by order approves the earlier effective date for good cause shown (lower natural gas rates for customers). XVI. WHEREFORE, Applicant requests the Commission issue its Order finding Applicant's proposed rates to be just, reasonable, and nondiscriminatory and to become effective for all natural gas serice on and after March 1,2012.

Seventeenth Revision Sheet 150 canceling Substitute Sixteenth Revision Sheet 150 Seventeenth Revision Sheet 150 updates the forward-looking cost of natural gas purchased for customer usage. These tarffs request an annual revenue decrease of approximately $4.1 milion, or about 6.00%. This request is a Purchased Gas Cost Adjustment (PGA) that is typically fied annually to reflect changes in the cost of gas purchased to sere customers. Any increases or decreases resulting from these PGA filings directly result from the cost of gas purchased in the marketplace; A vista makes no additional profits from these rate changes. If approved as filed a residential or small business customer served under Schedule 101 using an average of 62 therms per month can expect to see an average decrease of approximately $3.46 per month, or about 5.68%. Larger commercial customers served under Schedules 111 can expect to see an average decrease of about 7.30%, with the higher percentages due to lower base rates. However, actual customer decreases wil vary based on therms consumed. This fiing requests an effective date of March 1,2012.
