AVU-E-09~01 CASE NO. AVU-G-09-01 DIRECT TESTIMONY OF BRUCE W. FOLSOM (ELECTRIC AND NATURAL GAS) 1 2 I.INTRODUCTION Q.Please state your name, employer and business 3 address. 4 A.My name is Bruce Folsom. I am employed by Avista 5 as the Senior Manager of Demand Side Management (DSM). My 6 business address is East 1411 Mission Avenue, Spokane, 7 Washington. 8 Q.Would you please describe your education and 9 business experience? 10 A.I graduated from the University of Washington in 11 1979 with Bachelor of Arts and Bachelor of Science degrees. 12 i received a Masters in Business Administration degree from 13 Seattle University in 1984. 14 15 I joined the Company in 1993 in the State and Federal Regulation Department.My duties included work 16 associated with tariff revisions and regulatory aspects of 17 18 integrated resource planning,demand side management, competi ti ve bidding, and emerging issues.In 2002, I was 19 named the Manager of Regulatory Compliance which added 20 responsibilities such as implementing the Federal Energy 21 Regulatory Commission's maj or changes to its Standards of 22 23 24 Conduct rule.I began my current position in September of 2006.Prior to joining Avista, I was employed by the Washington Utilities and Transportation Commission 25 beginning in 1984, and then served as the Electric Program Folsom, Di 1 Avista Corporation 1 Manager from 1990 to February, 1993. From 1979 to 1983, I 2 was the Pacific Northwest Regional Director of the 3 Environmental Careers Organization, a national, private, 4 not-for-profit organization. 5 Q.What is the scope of your testimony in this 6 proceeding? 7 8 A.I provide an overview of the Company's DSM programs and recent results.I also provide documentation 9 showing that Avista' s expenditures for electric and natural 10 gas energy efficiency programs have been prudently 11 incurred. 12 Q.Are you sponsoring any exhibits to be introduced 13 in this proceeding? 14 A.Yes.I am sponsoring Exhibit No. 13 prepared 15 under direction. Exhibit No. 13 documents the results and 16 cost~effectiveness of Avista' s DSM programs. 17 18 19 II. DSM PROGRAS AN CURNT PERIOD RESULTS Q.Would you please provide a brief overview of 20 Avista' s DSM programs? 21 22 A.Yes. Avista has historically had a significant and consistent commitment to energy efficiency.In the 23 mid-1990s, while the electric industry was pulling back 24 from offering energy efficiency services, Avista pioneered 25 the Energy Efficiency Tariff Rider. Now in its fourteenth Folsom, Di 2 Avista Corporation 1 year, the tariff rider was the country's first distribution 2 charge to fund DSM and is now replicated in many other 3 states.Schedule 91 currently has a commodity rate of 4 1.58% for electric service and the Schedule 191 rate is 5 1.46% for natural gas. 6 The Company's approach to energy efficiency is based 7 on two key principles.The first is to pursue all cost- 8 effective kilowatt hours and therms by offering financial 9 incentives for energy saving measures with a simple 10 financial payback of over one year.The second key 11 principle is to use the most effective "mechanism" to 12 deliver energy efficiency services to customers.These 13 mechanisms are varied and include 1) prescriptive programs 14 (or "standard offers" such as high efficiency appliance 15 rebates), 2) site-specific or "customized" analyses at 16 customer premises,3 )"market transformational" ,or 17 regional, efforts with other utilities, 4) low-income 18 weatherization services through local Community Action 19 Agencies, and 5) low-cost/no-cost advice through a multi- 20 channel communication effort.These will be described 21 later in my testimony. 22 The Company's offerings include over 300 measures that 23 are packaged into over 30 programs for customer 24 convenience. As part of Avista' s planning efforts, over 25 3000 measures are considered and then examined for cost- Folsom, Di 3 Avista Corporation 1 effectiveness.The Company's comprehens i ve energy 2 efficiency outreach, the "Every Little Bit" communications 3 campaign, received several national honors in 2008.This 4 comprehens i ve communication approach helps customers 5 reorient their thinking about energy efficiency. 6 The Company's programs are delivered across a full 7 customer spectrum.Virtually all customers have had the 8 opportunity to participate and a great many have directly 9 benefited from the program offerings. As will be described 10 later in my testimony, all customers have indirectly 11 benefi ted through enhanced cost-efficiencies as a result of 12 this portfolio approach. 13 Avista offers the following residential programs: Folsom, Di 4 Avista Corporation 1 Illustration No.1: 2 RESIDENTIAL 3 High Efficiency Furnace/Boiler 4 High Efficiency Heat Pump 5 High Efficiency Variable Speed Motor 6 High Efficiency Tank Water Heater 7 High Efficiency Tankless Water Heater 8 High Efficiency Ground Source Heat Pump 9 High Efficiency Replacement Air Conditioning 10 Space Heat Conversion (Direct Use of Natural Gas) 11 Water Heat Conversion (Direct Use of Natural Gas) 12 Heat Pump Conversion (Direct Use of Natural Gas)13 Ceiling, Attic, Floor, Wall Insulation 14 High Efficiency Windows 15 Fireplace Damper 16 Multifamily (UCONS) 17 BuiltGreenā„¢ (New Construction Energy Star~) 18 Something for Everyone 19 Energy Star~ Appliances 20 CFL (and CFL Recycling) Promotions 21 Warm Homes, Warm Hearts 22 "Second" Refrigerator Recycling Program 23 "Geographic Saturation" 24 Communi ty Events and Workshops25 Low-cost/no-cost information26 Direct Use of Nat Gas: Multi-Family Housing Conversion 27 Regional Market Transformation (NEEA) 28 On-line Home Audits 29 30 LIMITED INCOME RESIDENTIAL 31 Limited Income Weatherization with Community Action 32 Programs33 (Note: All residential programs above are also34 available) 35 36 37 The residential programs shown above are standard 38 offerings or what we call "prescriptive programs."These 39 invol ve a menu of rebates on selected measures (e. g. , 40 lighting, weatherization, appliances, etc.). Folsom, Di 5 Avista Corporation 1 For commercial customers, in addition to prescriptive 2 programs, Avista offers "site-specific" programs. Site- 3 4 specific programs are customized to the cus tomer's premises.The site-specific offering provides incentives 5 on any cost-effective commercial and industrial energy 6 efficiency measure. This is implemented through site 7 analyses, customized diagnoses, and incentives determined 8 for savings generated specific to the customer's premises 9 or process. The following illustration shows the programs 10 available to Avista' s commercial and industrial customers. 11 Illustration 2: 12 NON-RESIDENTIAL (COMMRCIAL &: INDUSTRIAL)13 Site-Specific14 (Note: Incentives offered for any measure wi th ~ 1 15 year payback) 16 Air Care Plus (Rooftop HVAC Maintenance) 17 EnergySmart Commercial Refrigeration18 LEED Certification Incentives 19 Power Management for PC Networks 20 Premium Efficiency Motors 21 Food Service22 LED Traffic Signals 23 Refrigerated Warehouse 24 Commercial HVAC variable Frequency Drives 25 Retro-Commissioning 26 Clothes Washers 27 Side Steam and Demand Filtration 28 Vending Machine Controllers29 Lighting and Controls 30 31 32 These programs are supported by twenty-one full-time 33 equivalents (FTE) spread over 34 staff.(This does not 34 include Company support from the Contact Center, Corporate Folsom, Di 6 Avista corporation 1 Communications, Accounting and other direct and indirect 2 support. )The 2008 DSM budget (system) was over $18 3 million, representing an increase of $6 million over 2007. 4 Of the Company's revenues collected under Schedules 91 5 (electric tariff rider) and 191 (natural gas tariff rider) 6 in 2008, 70.9% was paid out to customers in direct 7 incentives pursuant to the cost-effecti veness tests 8 described below. This does not include additional benefits 9 such as technical analyses provided to cus tomers by the 10 Company's DSM engineering staff. 11 Q.What were the Company's energy efficiency targets 12 and results for 2008? 13 A.The Company's energy efficiency targets are 14 established in the process of developing the Electric and 15 Natural Gas Integrated Resource Plans (IRPs).These 16 targets are revisited and adjusted to take into account new 17 programs as part of our ongoing business planning process. 18 The results of Avista' s energy efficiency programs 19 continue to exceed the targets established as part of the 20 IRP process.The current estimate of local energy 21 efficiency savings for January through November 2008 is 22 62.1 million kWhs (approximately 7 amW) or 117% of the 23 Company's annual target. These preliminary results will be 24 revised based upon ongoing verification of the data by the 25 Company. Folsom, Di 7 Avista Corporation 1 These are preliminary, unaudited results that will 2 be updated. Over 137 aMW of cumulative savings have been 3 achieved through Avista' s energy efficiency efforts in the 4 past thirty years; over 110 aM of DSM is currently in 5 place on the Company's system. By comparison Avista's 2008 6 total electric retail load was 1098 aMW. The 2008 natural 7 gas savings targets for Washington and Idaho is 1.425 8 million therms.Over 1.75 million therms have been saved 9 through November of 2008, which is 123% of the 2008 annual 10 target. 11 Q.Do the 2008 results reflect Avista's 12 participation in regional energy efficiency efforts? 13 A.No.In addition to Avista's prescriptive and 14 site-specific programs, the Company funds and participates 15 in the activities of the Northwest Energy Efficiency 16 Alliance (NEEA). NEEA focuses on using a regional approach 17 to obtain electric efficiency through the transformation of 18 markets for efficiency measures and services.An example 19 of NEEA-sponsored programs that benefit Avista customers 20 are efforts to decrease the cost of compact fluorescent 21 light bulbs (CFLS)and high-efficiency appliances by 22 working through manufacturers. For some measures, a large- 23 scale, cross-utility approach is the most cost-effective 24 means to achieve energy efficiency savings. This approach 25 seems particularly effective for markets composed of large Folsom, Di 8 Avista Corporation 1 numbers of smaller usage consumers, such as the residential 2 and small commercial markets. 3 The results from NEEA programs for 2008 have not been 4 reported as of the date of the submittal of this testimony. 5 Historically, however, Avista has received approximately 6 1.5 aMW of savings in its service terri tory from NEEA 7 programs. 8 Q.Please explain Avista · s relationship to the 9 Northwest Energy Efficiency Alliance (NEEA). 10 A.Avista has been a member of the NEEA since the 11 creation of that organization in 1996. As stated above, the 12 mission of NEEA is to acquire cost-effective electric 13 efficiency resources through regional market 14 transformation. Avista is supportive of the use of a 15 coordinated regional market transformation effort to the 16 extent that the effort is a cost-effective enhancement of, 17 or alternative to, local utility efforts at acquiring those 18 resources for our customers. 19 In 2007, the last year for which data is available, 20 NEEA acquired 2.0 aMW applicable to Avista' s service area 21 at a cost of 0.07 cents/kWh. Avista' s Total Resource Cost 22 avoided cost for a comparable time period is 0.4 cents/kWh 23 (using Avista' s weighted average measure life and discount 24 rate). Historically, NEEA' s TRC acquisition cost has always Folsom, Di 9 Avista Corporation 1 been well below Avista' s comparable electric avoided cost. 2 The value of the NEEA portfolio has been realized by 3 Avista' s customers both directly as participants in markets 4 that have been cost-effectively transformed by NEEA 5 ventures, as well as indirectly as a result of reduced 6 demand and consequently lower energy costs through 7 wholesale markets. 8 Avista has been actively involved in the governance of 9 NEEA since the creation of the organization. The governance 10 contains numerous safeguards to promote broad regional 11 representation (including representation of the interests 12 of customers east of the Cascades and investor-owned 13 utility customers), prudent oversight of organizational 14 expenditures by the board of directors and appropriate 15 opportunities for the cessation of Avista funding in the 16 event of changes in organizational mission or 17 effectiveness. 18 Q.How do you increase customer participation in 19 your DSM programs? 20 A.Our focus on the residential side is to increase 21 customer understanding of our programs and how our programs 22 can help customers reduce their bills. We do this through 23 bill inserts and communications to drive customers to our 24 website with a "call-to-action" to use our financial 25 rebates. The following depicts a recent enhancement to our Folsom, Di 10 Avista Corporation 1 This is an interactivewebs i te, ww.EveryLitteBit.com . 2 tool to engage customers and allows customers to quickly 3 by "clicking on"view programs that they can use, 4 particular features of the dwelling: 5 Illustration No.3: 6 7 8 9 10 11 12 13 14 15 16 17 18 19 Q.Have you reviewed the Staff's comments on Energy Avista's response theirisAffordability and what 20 recommendations? 21 22 GNR-U-08-01,"EnergyA.Yes.In Case No. Affordabili ty Issues and Workshops, "the Commission 23 ini tiated workshops to provide a forum for the exploration 24 of issues related to the affordabili ty of energy in Idaho. 25 Staff provided their comments November 26, 2008.In the Folsom, Di 11 Avista Corporation 1 Company's reply comments filed December 19, 2008, we agreed 2 with Staff's recommendations concerning DSM and noted that: 3 . The Company historically has addressed 4 weatherization funding levels in our rate cases; 5 . Avista has been an advocate for energy conservation6 education; 7 . Avista continues to review our incentive programs 8 and the level of incentive amounts on an ongoing9 basis; 10 . Regarding low- or no-interest loans, we are11 examining expansion of current customer options,12 preferring to work with the existing financial13 institution infrastructure that has this function14 as their primary service; 15 . Avista strongly supports ini tiati ve (s), including16 those by the Northwest Energy Efficiency Alliance, 17 to include multi-family and manufactured homes in 18 the Energy Star~ Home Program; and 19 . Avista supports improved appliance and building20 standards and codes as the most cost-effective21 means for energy efficiency delivery. 22 23 Q. What is the status of the tariff rider balance? 24 25 A.The tariff rider balance both Idaho and washington, electric and natural gas is a negative 26 $9,982,000 (i.e. dollars expended exceed dollars collected 27 28 through the Tariff Rider).By jurisdiction and fuel, the negative rider balances are,as of November 2008: 29 ($1,149,000) - Idaho electric; ($858,000) - Idaho natural 30 gas; ($5,499,000) - Washington electric; and ($2,476,000) - 31 Washington natural gas. 32 Q. What are the causes of these increasing negative 33 balances? Folsom, Di 12 Avista Corporation 1 A.The Company has leveraged the high level of 2 public interest in 'green' technologies to enhance the 3 acquisition of cost-effective energy-efficiency measures. 4 These leveraging opportunities and the customer response to 5 the Company's efficiency programs have exceeded our 6 expectations. 7 Q.What is the Company's plan to address these 8 balances? 9 A.The largest negative balances, or over 78%, are 10 in Washington. On December 31, 2008, we filed tariff rider 11 revisions in Washington to reduce the Washington tariff 12 rider balances to zero. By means of a separate filing, to 13 follow soon after the filing of this case, we will submit 14 revised tariff riders in idaho to do the same.We are 15 filing the tariff rider revisions separate from this 16 general rate case so that the revisions can go into effect 17 ear ly in 2009 , if approved, and thereby, preven t an 18 increasing negative balance. 19 Q.What plans does the Company have in the future to 20 address these tariff rider balances? 21 A.Schedules 91 and 191 should be the equivalent of 22 a "true-up mechanism" that is revised annually to reflect 23 expenditures to fund energy efficiency programs.In the 24 past few years, customer demand for energy efficiency 25 programs has been greater than available funding, which has Folsom, Di 13 Avista Corporation 1 resulted in the need for increased energy efficiency 2 funding.Avista remains committed to expeditiously 3 responding to customer requests for funding where the cost- 4 effectiveness tests are satisfied. 5 Q.What kind of external oversight does the Company 6 have regarding DSM? 7 A.The Company established a non-binding oversight 8 group, the External Energy-Efficiency (Triple-E) board in 9 1999 to provide for improved opportuni ties for 10 communication,input and oversight of Avista' s DSM 11 portfolios.Avista currently facilitates meetings of the 12 board twice per year, provides a full analysis of the 13 results of DSM operations on an annual or more frequent 14 basis, discloses (with appropriate concern for customer 15 confidentiality) large projects and projects benefiting 16 Avista facilities, and provides the Triple-E with a 17 quarterly update of DSM activities.Additionally, the 18 Triple-E board can initiate additional meetings of the 19 board at their own request. Board membership has included 20 representatives from regulatory, governmental, 21 environmental, nationally recognized energy-efficiency 22 experts,cus tomer advoca tes for 1 imi ted income and 23 industrial segments as well as end-use customer 24 participants. Folsom, Di 14 Avista Corporation 1 Q.Does the Company propose to increase its low- 2 income weatherization funding as part of this filing? 3 A.Yes.The Company proposes to increase its low- 4 income weatherization funding for electric and natural gas 5 service by a percentage amount equal to the percentage rate 6 increase granted in this case for residential customers 7 (net of the PCA surcharge reduction for electric service). 8 The additional funding would be provided through the DSM 9 tariff riders, Schedules 91 and 191. 10 11 12 III. PRUDENCE OF INCURRD DSM COSTS Q.Would you please explain the Company's request 13 for a finding of prudence in this case? 14 A.Yes. When the Commission approved the Company's 15 energy efficiency programs in 1995 (in Case Uos. WWP-E-94- 16 12 and WWP-G-94-6), Avista committed to demonstrating the 17 prudence of program expenditures in future general rate 18 cases.In the Company's last general electric and natural 19 gas rate cases (Case Nos. AVU-E-08-01 and AVU-G-08-01), the 20 Commission issued a finding in Order No. 30647 that 21 electric and natural gas expenditures through December 31, 22 2007 were prudently incurred.At this time, the Company 23 requests that the Commission issue a finding that electric 24 and natural gas energy efficiency expenditures from January 25 1, 2008 through November 30, 2008 were prudently incurred. Folsom, Di 15 Avista Corporation 1 Would you please sumrize the Company's energyQ. 2 efficiency-related savings for this time period? 3 Yes. The Company's tariff riders under SchedulesA. 4 91 (electric) and 191 (natural gas) are system benefit 5 charges to fund energy efficiency. 6 As shown in Exhibit No. 13, from January 1, 2008 7 through November 30, 2008, 62.1 million kWh and 1.75 8 million therms of energy savings were obtained.Page 1 of 9 Exhibit No. 13 details the energy savings by regular and 10 low-income portfolios for both electric and natural gas DSM 11 programs. 12 Has there been ongoing review of the Company'sQ. 13 programs? 14 Yes, as previously discussed, the Company hasA. 15 regularly convened a stakeholders forum known as the 16 External Energy Efficiency Board.These meetings have 17 18 19 included representatives,Commission staffcustomer members,and indi viduals from the environmen tal communities.These stakeholder meetings review the 20 Company's program offerings as well as the underlying cost- 21 22 23 24 25 effecti veness tests and resul ts . Q.Have the Company's DSM programs been cost- effective? A.Yes.The electric programs have been cost- effective from both a Total Resource Cos t (TRC)and Utility Folsom, Di 16 Avista Corporation 1 Cost Test (UCT) perspective.Page 2 of Exhibit No. 13 2 shows that the TRC benefit-to-cost ratio of 1.94 for the 3 overall electric DSM program portfolio is cost-effective, 4 with a net TRC benefit to customers of over $23 million. 5 The UCT benefit-to-cost ratio is cost-effective with a net 6 UCT benefit of over $32 million. The levelized TRC and UCT 7 cost is 4.8 cents and 2.3 cents per kWh, respectively. The 8 overall portfolio of measures has a weighted average 9 measure life of 13 years. The comparable levelized electric 10 avoided cost for a measure of this life is 8.7 cents per 11 kWh.The electric DSM programs were also cost-effective 12 under the Participant Test. 13 Page 3 of Exhibit No. 13 illustrates the natural gas 14 DSM program portfolio cost-effectiveness under both the TRC 15 and UCT tes ts .But for one customer, the Company's TRC 16 would be 1.16, with any number above 1.00 being cost 17 effective.This customer, based on their own initiatives, 18 spent $4.2 million on energy efficiency projects of which 19 Avista contributed $247,000.Avista's contribution of 20 $247,000 divided by the 104,000 therms of savings from 21 these projects results in a $2.36 per first year therm 22 utility incentive investment, in comparison to an avoided 23 cost value of àpproximately $10 for a therm of the measure 24 life associated with those projects.Apart from this 25 customer, the TRC and UCT benefit cost ratios are 1.16 and Folsom, Di 17 Avista Corporation 1 2.64 respectively. Therefore, except for the one customer, 2 the natural gas DSM portfolio passes both the TRC and UCT 3 tests. 4 Q.Please sumarize the Company's conclusions. 5 6 A.The Company's expenditure of tariff rider revenue has been reasonable and prudent.A portfolio of programs 7 covering all customer classes has been offered with a total 8 savings of over 62.1 million annual kWhs and 1. 7 million 9 therms during January 1, 2008 through November 30, 2008. A 10 13-year levelized utility cost per saved kilowatt hour of 11 2.3 cents per kWh has been achieved. The levelized avoided 12 costs during this similar period has been 8.7 cents per 13 kWh.The 15 year levelized utility cost per saved therm 14 has averaged 37.1 cents per thermo 15 The Tariff Rider and programs have been very 16 successful. Participating customers have benefited through 17 lower bills. Non-participating customers have benefited 18 from the Company having acquired lower cost resources as 19 well as maintaining the energy efficiency message and 20 infrastructure for the benefit of our service territory. 21 In closing, Avista respectfully requests that the 22 Commission issue a finding of prudence for energy 23 efficiency expenditures from January 1,2008 through 24 November 30, 2008.
