INTRODUCTION 2 Avista Corporation, doing business as Avista Utilities (hereinafter Avista or 3 Company), at 1411 East Mission Avenue, Spokane, Washington, respectfully proposes 4 revisions to Schedule 190, "Natural Gas Efficiency Programs." The purpose of this tariff 5 revision is to suspend the Company's natural gas demand-side management (DSM) programs 6 due to new natural gas avoided costs that have been released as part of Avista's Integrated 7 Resource Plan (IRP) process. 8 The Company requests that this filing be processed under the Commission's Modified 9 Procedure rules. 10 Communications in reference to this Application should be addressed to: 11 12 13 14 15 16 17 18 19 20 David J.

Mission Avenue, MSC-29 Spokane, WA 99220-3727 Phone: (509) 495-4975 linda.gervais@avistacorp.com 21 II. BACKGROUND 22 The changing natural gas supply picture and resultant lower prices have resulted in 23 the decline of natural gas avoided costs. While this is good news for consumers of natural 24 gas, these lower avoided costs add new challenges to offering a comprehensive natural gas 25 DSM portfolio. 26 Avista identified last fall, as part of its annual DSM Business Planning process, the 27 need to monitor natural gas avoided costs to optimize, and maintain the cost-effectiveness of 28 its natural gas DSM portfolio. This optimization was further analyzed and discussed in a Application of Avista Corporation Page 1 Case No. AVU-G-12 1 report entitled "Review of Prospects and Strategies for the 2012 Avista Regular Income 2 Natural Gas DSM Portfolio," dated February 2012. The analysis was based on a natural gas 3 avoided cost that was expected to be 25% lower than the existing avoided costs. Further, this 4 analysis concluded that a smaller menu of natural gas programs could and would be fielded 5 later in 2012. This however, changed with the release of avoided natural gas costs that are 6 now approximately 50% lower than the existing avoided costs. The effect of these lower 7 avoided costs is to render the natural gas energy efficiency portfolio programs to not be cost- 8 effective going forward. Avista's natural gas IRP is scheduled for release on August 31, 9 2012; standard practice is to re-file avoided costs thereafter. However, given that the 10 Company is aware of the lower avoided costs, we are opting to immediately begin the phase- 11 out of these programs, subject to existing contractual and outstanding offers of service. 12 II. COST TEST ANALYSIS 13 Avista has scrutinized several scenarios in an attempt to ascertain if any reasonable 14 calculation of the DSM portfolio or modifications to the avoided cost would yield a portfolio 15 that is cost-effective under the Total Resource Cost (TRC) test. The major scenarios 16 included: 17 18 • The addition of a carbon cost adder for 2013-2019 (in addition to the carbon cost that 19 is incorporated into the avoided cost itself for 2020 and beyond); 20 • The inclusion of a natural gas distribution capacity cost value; 21 • The use of an interpretation of the TRC test on a gross (including all program 22 participants) rather than a net (based upon those participants who adopted the 23 measure due utility intervention) basis; 24 • Various alternative categorizations of net-to-gross ratios and realization rates by 25 program; and 26 • Different means of allocating non-incentive utility costs across programs. 27 Application of Avista Corporation Page 2 Case No. AVU-G-12 1 None of the scenarios tested above resulted in a portfolio that was projected to be 2 cost-effective under the TRC. Generally, the most optimistic scenarios led to benefit-to-cost 3 ratios in the low 0.70 range. 4 The Company remains committed to a continual re-evaluation of the prospects for the 5 natural gas DSM portfolio. Should natural gas costs, technologies or delivery methods 6 change in such a manner to allow for cost-effective opportunities in the future, the Company 7 will move to return all or portions of the natural gas DSM portfolio to the Company's overall 8 energy-efficiency strategy. 9 III. PROPOSED TRANSITION OF PROGRAMS 10 Regarding the procedure for suspending these programs, Avista has outstanding 11 contractual obligations and existing rebate offers in the marketplace. The accompanying 12 proposed tariff revision addresses the three natural gas DSM portfolios as follows: 13 Site Specific Programs: 14 Avista will honor all terms and conditions of contracts and agreements that are fully 15 executed prior to September 1, 2012. Natural gas energy efficiency projects, known 16 to Avista prior to September 1, 2012, but without fully executed contracts, will be 17 honored if Avista has already conducted an analysis of a proposed natural gas energy 18 efficiency measure. If the Company has not already conducted an analysis of a 19 proposed natural gas energy efficiency measure, customers seeking incentive funding 20 must submit an overview of the proposed natural gas energy efficiency project to the 21 Company in writing or via email by September 1, 2012. Projects must have material 22 documentation by October 15, 2012 and an energy efficiency agreement must be 23 signed by January 15, 2013. 24 25 Residential and Non-Residential Prescriptive Rebate Programs: 26 Qualifying customers in the Company's Residential and Non-Residential Prescriptive 27 Rebate Programs must send to Avista all required rebate forms and other required 28 documentation postmarked by November 1, 2012 to be eligible for payment. Any 29 requests postmarked after November 1, 2012 will be denied payment. 30 31 Limited Income Programs: 32 All existing 2012 Community Action Partnership contracts with natural gas 33 incentives will be honored. No additional natural gas measures will be funded 34 effective January 1, 2013. 35 Application of Avista Corporation Page 3 Case No. AVU-G-12 1 IV. CUSTOMER NOTIFICATION 2 Notice to the public of the proposed revisions, pursuant to IDAPA 31.21.02.102, will 3 be given simultaneously with the filing of this Application by posting a notice to the 4 Company's Website. 11 'AI Cox, 1tSti[s1X1 6 While low natural gas avoided costs causes natural gas DSM programs to no longer 7 be cost-effective, lower natural gas avoided costs causes the direct use of natural gas to be 8 more cost-effective. Thus, Avista will propose, in a future electric efficiency filing, that 9 incentives for conversion of end-use equipment from electricity to natural gas be increased. 10 This would have multiple customer benefits, including efficiency of fuel use, support of the 11 trade ally network, and keeping the efficiency message in the marketplace. 12 The Company requests a revision to Schedule 190 to suspend natural gas demand- 13 side management (DSM) programs due to new natural gas avoided costs that have been 14 released as part of Avista's Integrated Resource Plan (IRP) process. 15 WHEREFORE Applicant respectfully requests the Commission approve the 16 proposed revisions to Schedule 190 attached to this Application, and effective for service 17 rendered on and after September 1, 2012, with this application being processed under 18 Modified Procedure. 19 20 21 22 23 24 Application of Avista Corporation Page 4 Case No. AVU-G-12 DATED at Spokane, Washington, this 28th day of June, 2012. 2 3 AVISTA CORPORATION 4 5 6 By 14 'A4 7 David J.
