Please explain the basis for this allowance. RESPONSE: Avista's provision to allow up to l0 percent of its conservation budget to be spent on projects and "programs whose savings impacts have not yet been measured if the overall conservation portfolio passes the applicable cost-effectiveness test"l, as stated in its 2020 and202l ACRs, is an internal Company policy intended to support new and emerging technologies and applications. In addition to funding new measures, Avista often elects to use this funding to devise methods to evaluate savings for new programs, measures, and technologies. Avista believes this practice is a critical tool for ensuring that the Company's efficiency portfolio continues to support customers' evolving energy needs. Avista also sees this exploration of evaluation plans for new measures as a necessary component of the Company's overall approach to evaluation, measurement, and verification. | 2020 ard202l ACRS at pg. 10. AVISTA CORPORATION RESPONSE TO REQITEST FOR INFORMA',TTON JURISDICTION: IDAHO CASE NO: AVU-E-22-13/AW-G-22-05 REQUESTER: IPUC StaffTYPE: Production Request REQUEST NO.: Staff- 19 DATE PREPARED: 1011712022WITNESS: N/A RESPONDER: Ryan Finesilver DEPARTMENT: Energy Efficiency TELEPHONE: (509) 495-4873 REQUEST: Please describe the Company's efforts to address the realization rates for the 2020 and 2021 Residential Fuel Efficiency and the202l Residential Appliances measures. RESPONSE: Avista recognizes that the realization rate for the Residential Fuel Efficiency program in 2021 was 83.50yo, resulting in savings being adjusted downward from702,026krnhto 586,226 kWh. The Company notes that as part of the impact analysis for Residential Fuel Efficiency for program year 2021, the evaluator attempted to conduct a billing analysis, but participation in such analysis was insufEcient to complete the verified savings using this methodology. As an alternative, the evaluator used 2020 billing analysis results instead. To avoid such adjustments in realization rates and provide for the most recent data available for savings verification in the future, Avista will continue to work with its evaluator to pursue higher participation in billing analyses and to obtain sufficient data to determine if an adjustment to the Unit Energy Savings (UES) value may be appropriate. The Residential Appliance progfttm is a newer oflering to Avista's portfolio but has already achieved its place in the market for customers that want to pursue energy efficient options for clothes washers and dryers. ln the 2021 prograrn year, Avista incented 152 customers with a total incentive expense of $5,590. This particular program received arealization rate of 78% due to two factors: first, one of the 13 sampled washers was found to have not qualified due to minimum volume requirements specified by the RTF, and second, the evaluator found that 3 of the washers were "top loading" machines, which have lower savings than "front loading" options. To address this, Avista has created a second washer UES value to account for both front loading and top loading washers. The top loading measure has less savings associated with it but will avoid realization rate adjustnents in the future. AVISTA CORPORATION RESPONSE TO REQUEST FOR TNFORMATION ruRISDICTION: CASE NO: REQUESTER: TYPE: REQUEST NO.: IDAHO AYU -E -22- l 3 /AVU- G -22 -0 5 IPUC Staff Production Request Staff - 20 DATE PREPARED: l0ll7 12022WITNESS: N/A RESPONDER: Ryan Finesilver DEPARTMENT: Energy Efficiency TELEPHONE: (509) 495-4873 REQUEST: Please describe the Company's efforts to address the cost effectiveness of the Low-Income Weatherization pro gram. RESPONSE: Avista continues to seek out measures that contribute to low-cost, cost-effective conservation, and make those offerings part of its Low-Income Weatherization program. However, most of these proposed additions do not produce a high level of savings as associated with water heat and space heat measures. Because the low-income program aims to fully fund measures for low-income families, achieving cost-effectiveness is-and historically has been-a challenge. With extemal market pressures such as inflation, supply chain issues, and labor shortages, the per-unit cost of installed equipment is expected to increase in the future which puts further pressure on the Utility Cost Test. Avista also monitors the claimed savings values associated with the low-income programs to determine if adjustments are needed. While this process can take into consideration the evaluated savings over several years, Avista continues to monitor each year's realization rates for any addressable concerns that would result in a UES value change. AVISTA CORPORATION RESPONSE TO REQUEST FOR INFORMATION ruRISDICTION: IDAHO CASE NO: AYU-E-22-13/AW-G-22-05 REQUESTER: TPUC StAffTYPE: Production Request REQUEST NO.: Staff- 2l DATE PREPARED: l0ll7 12022WITNESS: N/A RESPONDER: Ryan Finesilver DEPARTMENT: Energy Efficiency TELEPHONE: (s09) 495-4873 REQUEST: The Company indicates that the completion of significant Commercial and Industrial projects are expected to increase the cost-effectiveness of the natural gas program.202l Annual Conservation Report at 30. Please provide a list of these projects, including a brief description and expected completion date for each. RESPONSE: In noting in its 2021 ACR that "As significant projects are completed...future years could see a material shift in CE with avoided cost benefits far exceeding the costs of providing those benefits.", the Company was not referring to a specific or known project but rather recognizing that any level of increased participation in the natural gas progftlm would result in a significant increase to the cost efflectiveness. Commercial programs are tested for cost-effectiveness before they are added to the overall Energy Efficiency program to ensure they will contribute to a cost-effective portfolio. More activity flowing through the natural gas progftrms would result in a higher benefit value (Avoided Cost) in comparison to the costs (Incentives, Admin Costs).
